Building Privilege Escalation Chains

So, you want to talk about how attackers chain together different steps to get more power on a system? It’s a bit like building with LEGOs, but instead of colorful bricks, they’re using security weaknesses. We’re going to break down how they do it, the common tricks they pull, and what you can do to stop them. It’s all about understanding the whole process, not just one single hack. This article is going to look at the whole picture of privilege escalation chain building.

Key Takeaways

Privilege escalation is when an attacker gets more control than they should, moving from basic access to admin-level power.
Attackers build these chains by exploiting software bugs, bad settings, weak passwords, and other security holes.
Getting a foothold and then moving around the network are key steps before they can really escalate privileges.
Stopping these attacks means using the least amount of privilege needed, keeping software updated, and watching for weird activity.
The methods attackers use are always changing, with new targets like cloud services and containers becoming more common.

Understanding Privilege Escalation Chains

Defining Privilege Escalation

Privilege escalation is essentially a way for an attacker to get more power on a system than they were initially given. Think of it like getting a key to a single room, and then figuring out how to use that key to get keys to the whole building. It’s a core technique in many cyberattacks, allowing someone who’s already managed to get a small foothold to expand their access and control. This isn’t just about getting administrative rights; it’s about moving from a limited user account to one that can manage the entire system, access sensitive data, or even disable security measures. The goal is to gain deeper control, which is why it’s so important for attackers to achieve.

The Role of Privilege Escalation in Cyberattacks

Once an attacker gets into a network, often through a less secure entry point like a phishing email or a vulnerable web application, they rarely stop there. Privilege escalation is the next logical step. It’s how they turn a minor intrusion into a major compromise. Without it, an attacker might be stuck with limited access, unable to do much damage. But with elevated privileges, they can achieve a variety of objectives:

Persistence: Ensuring they can maintain access even if the initial entry point is closed.
Lateral Movement: Moving from the initially compromised system to other machines on the network.
Data Exfiltration: Accessing and stealing sensitive information.
System Disruption: Causing damage or disabling services.
Camouflage: Hiding their activities by using legitimate administrative tools.

Essentially, privilege escalation is the bridge between initial access and achieving the attacker’s ultimate goals. It’s a critical phase in the intrusion lifecycle.

Impact on Business Operations

The consequences of successful privilege escalation can be severe for any business. When an attacker gains administrative control, they can potentially access and steal customer data, financial records, or intellectual property. This can lead to significant financial losses, regulatory fines, and damage to the company’s reputation. Beyond data theft, attackers can disrupt operations by shutting down critical systems, encrypting data for ransom, or deploying destructive malware. The ability to move freely and control systems means that a single successful escalation can cascade into a widespread incident, impacting everything from daily operations to long-term business viability. Organizations with excessive user permissions are at a higher risk, as this expands the potential attack surface [811b].

Common Attack Vectors for Privilege Escalation

So, how do attackers actually get that extra power they need? It’s not usually a single magic trick. Instead, they look for weak spots, and there are a few common places they tend to find them. Think of it like finding a loose window or an unlocked back door instead of trying to break down the front.

Exploiting Software Vulnerabilities

Software, no matter how well-made, can have bugs. Attackers are really good at finding these bugs, especially in older or unpatched programs. When a program has a flaw, it might let someone run commands they shouldn’t be able to, or access files that are off-limits. It’s like finding a shortcut in a maze that leads straight to the center.

Unpatched Systems: This is a big one. If a company doesn’t update its software regularly, known security holes remain open. Attackers scan for these known issues. You can find more about how attackers deliver these exploits here.
Zero-Day Exploits: These are bugs that are so new, even the software maker doesn’t know about them yet. Attackers who find these have a significant advantage because there’s no defense ready.
Vulnerable Drivers and Plugins: Sometimes, it’s not the main software that’s the problem, but smaller pieces that add functionality. These can be just as risky if they aren’t kept up-to-date.

Leveraging Insecure Configurations

Sometimes, the software itself is fine, but how it’s set up creates problems. Think about leaving your house keys under the doormat – the lock is good, but the setup is weak. Attackers look for these kinds of misconfigurations.

Default Settings: Many systems come with default usernames and passwords (like ‘admin’/’password’). If these aren’t changed, it’s an easy win for an attacker.
Unnecessary Services: Running services that aren’t needed can open up extra ways for attackers to get in or move around.
Weak Permissions: Files and folders might be set to be accessible by too many people, allowing unauthorized access or modification.

Attackers often look for systems that have been set up quickly without much thought given to security. These "quick and dirty" setups can leave doors wide open.

Abusing Weak Access Controls

This is all about who is allowed to do what. If the rules for access aren’t strict enough, people (or attackers pretending to be people) can do more than they should.

Over-Privileged Accounts: Giving users more permissions than they actually need for their job is a common mistake. If that account gets compromised, the attacker gets all those extra permissions too.
Lack of Multi-Factor Authentication (MFA): Relying on just a password is risky. MFA adds an extra layer, like a code from your phone, making it much harder for someone to get in with just stolen credentials.
Poor Session Management: If a system doesn’t properly end a user’s session after they log out or after a period of inactivity, an attacker might be able to reuse an old session.

Credential Weaknesses and Reuse

Passwords are often the weakest link. Attackers know this and have several ways to exploit them.

Password Reuse: This is huge. People tend to use the same password across many different websites and services. If one site gets breached and passwords are leaked, attackers try those same passwords everywhere else. It’s a simple but effective tactic used in many attacks.
Weak Passwords: Passwords that are easy to guess (like ‘123456’ or ‘password’) are a prime target for brute-force attacks.
Credential Dumping: Attackers might try to steal password hashes directly from a system’s memory or storage, then try to crack them offline.

These vectors often work together. An attacker might find an unpatched piece of software, use it to get a foothold, then look for weak passwords or misconfigurations to gain higher privileges.

Building the Foundation for Privilege Escalation Chain Building

Before you can even think about chaining together privilege escalation techniques, you need a solid understanding of where you are and how you got there. It’s like planning a heist; you wouldn’t just walk in blind. You need to know the layout, the security measures, and who’s on duty.

Initial Access and Footholds

This is where it all begins. How did the attacker first get into the system? This initial access is the first domino. It could be anything from a phishing email that tricked an employee into clicking a bad link, to exploiting a known vulnerability in a public-facing web server. Sometimes, it’s as simple as using weak or reused credentials that were found in a data breach elsewhere. The key here is that the attacker gains a foothold, a starting point from which they can begin their work. Without this initial entry, there’s no chain to build.

Understanding the Intrusion Lifecycle

Attackers don’t just magically get administrator rights. They follow a path, often referred to as the intrusion lifecycle. Recognizing these stages helps you anticipate the attacker’s next move. It typically starts with reconnaissance, then initial access, followed by establishing persistence, escalating privileges, moving laterally across the network, and finally, achieving their objective, which might be data exfiltration or system disruption.

Understanding the typical stages of an intrusion lifecycle is vital for defenders. It allows for the placement of detection and prevention controls at critical junctures, disrupting the attacker’s progress before they reach their ultimate goal.

Mapping Attack Surface and Exposure

What are the potential entry points into your environment? This is your attack surface. It includes everything from your network interfaces and web applications to user accounts and even third-party services you rely on. The bigger and more complex your attack surface, the more opportunities an attacker has. Reducing this surface area by closing unnecessary ports, disabling unused services, and properly configuring security controls is a major step in making your environment harder to compromise. It’s about knowing what’s exposed and minimizing that exposure. You can’t protect what you don’t know exists, so mapping it out is step one. This involves looking at things like exposed services and understanding how they might be targeted.

Techniques for Gaining Elevated Access

Once an attacker has a foothold in a system, the next logical step is to try and get more control. This is where privilege escalation comes into play. It’s all about moving from a regular user’s permissions to something more powerful, like administrator or even root access. This allows them to do a lot more damage, like installing malware, stealing sensitive data, or moving deeper into the network.

Exploiting Kernel Vulnerabilities

The operating system’s kernel is the core of the system, managing everything. If there’s a flaw in the kernel, it can be a goldmine for attackers. These vulnerabilities, often discovered through security research or sometimes by accident, can allow an attacker to execute code with the highest level of privilege. Think of it like finding a master key that opens every door in a building. Exploiting these often requires specific knowledge of the OS version and the exact vulnerability. It’s a high-risk, high-reward technique for attackers, and keeping systems patched is the best defense against it.

Abusing System Services and Processes

Many systems run background services and processes that have elevated privileges to do their jobs. Sometimes, these services are misconfigured, or they might have their own vulnerabilities. An attacker could potentially interact with these services in a way that tricks them into performing actions on behalf of the attacker, but with the service’s higher privileges. This is a bit like tricking a security guard into letting you into a restricted area. It often involves understanding how specific services work and finding ways to manipulate their normal operations. Some attackers might even try to replace a legitimate service with a malicious one if they can.

Stealing Administrative Credentials

This is a pretty straightforward, though often effective, method. If an attacker can get their hands on the login details for an administrator account, they can simply log in as that administrator. This can happen in a few ways: phishing attacks, finding passwords stored insecurely on the system, or using tools to dump credentials from memory. Sometimes, attackers will try to guess common administrator passwords or use passwords that have been leaked from other breaches. It highlights why strong password policies and multi-factor authentication are so important. Getting these credentials can bypass many other security measures because the attacker is acting as a legitimate, high-privilege user. This is a common way to move from initial access to deeper control, especially in environments where internal network trust is high.

Leveraging Legacy System Weaknesses

Older systems, especially those that are no longer actively supported or patched by the vendor, can be a treasure trove of vulnerabilities. These systems might have known flaws that have been fixed in newer versions but remain unaddressed in the legacy environment. Attackers can exploit these known weaknesses to gain elevated access. It’s like finding an old, unlocked back door to a building because the lock hasn’t been updated in years. These systems are often kept around for compatibility reasons, but they represent a significant risk. Dealing with them usually involves isolating them from the rest of the network or finding compensating controls if they can’t be updated or replaced. Sometimes, attackers will specifically look for these older systems to exploit, knowing that defenses might be weaker there. This can be a way to bypass more modern security measures that are in place on newer systems, as seen in some dropper malware techniques that exploit system vulnerabilities.

Lateral Movement and Chain Expansion

Once an attacker has a foothold in a network, the next logical step is to expand their reach. This is where lateral movement comes into play. It’s essentially the process of an attacker moving from one compromised system to others within the same network. Think of it like a burglar who, after getting into one room of a house, starts trying to open doors to other rooms, looking for more valuables or a way to get to the main safe.

Post-Compromise Network Navigation

After gaining initial access, attackers don’t usually stop at the first machine. They need to explore the network to find valuable targets, like domain controllers, sensitive data repositories, or systems with higher privileges. This exploration involves understanding the network layout, identifying key systems, and finding pathways to move around. Attackers might use tools to scan the network, map out connected devices, and identify potential next steps. This phase is critical for them to understand the environment they’ve landed in and plan their next moves.

Utilizing Stolen Credentials for Movement

One of the most common and effective ways attackers move laterally is by using stolen credentials. If they manage to get their hands on valid usernames and passwords, or even session tokens, they can often log into other systems as if they were legitimate users. This bypasses many perimeter defenses because the traffic looks normal. Techniques like pass-the-hash or pass-the-ticket are often employed here, allowing attackers to authenticate to new systems without needing the actual password. It’s a direct way to impersonate trusted users and gain access to more resources. This is why strong credential management and monitoring for unusual login activity are so important for preventing unauthorized access.

Exploiting Trusted Connections and Services

Attackers also look for ways to exploit trust relationships between systems or services. If one system is trusted by another, an attacker might be able to use that trust to move across. For example, if a server trusts a particular client for authentication, an attacker might impersonate that client. They might also abuse services that allow remote connections or administrative access, especially if those services are misconfigured or have weak authentication. This can include things like exploiting Remote Desktop Protocol (RDP) if it’s exposed internally, or using administrative tools that are accessible from compromised machines. Building a strong Identity and Access Management strategy is key to limiting these kinds of movements.

Here’s a look at common methods attackers use for lateral movement:

Credential Dumping: Extracting credentials from memory or files on a compromised system.
Pass-the-Hash/Ticket: Reusing authentication hashes or tickets to access other systems.
Exploiting Remote Services: Abusing protocols like RDP, SSH, or WinRM.
Scheduled Tasks/Services: Creating or modifying scheduled tasks or services to run malicious code on other machines.
Shared Folders and Drives: Accessing and executing files from network shares.

The goal of lateral movement is to expand the attacker’s control and access across the network, moving from an initial, often low-privilege, foothold to more critical systems and data. This expansion is what allows an attack to scale from a single compromised endpoint to a widespread breach.

This phase is where an attacker really starts to build out their access, turning a small intrusion into a significant compromise. It’s a critical part of the attack chain that defenders need to actively monitor and disrupt.

Advanced Privilege Escalation Tactics

Beyond the common methods, attackers often employ more sophisticated techniques to achieve elevated privileges. These advanced tactics can be harder to detect and exploit deeper weaknesses within systems and applications.

Exploiting Insecure APIs

Application Programming Interfaces (APIs) are the connective tissue for many modern applications and services. When APIs aren’t properly secured, they can become a direct pathway for attackers. This often involves bypassing authentication or authorization checks, or exploiting flaws in how the API handles data. For instance, an API might incorrectly trust client-side validation, allowing an attacker to send malformed requests that grant unintended access. Think of it like finding a back door to a building that was supposed to be locked, but the lock was faulty. Properly securing APIs means implementing strong authentication, granular authorization, and rigorous input validation for every request. It’s about treating every API endpoint as a potential entry point that needs strict controls, much like securing network boundaries.

Hardcoded Credentials and Secrets Management

Sometimes, developers embed sensitive information like passwords, API keys, or encryption keys directly into application code or configuration files. This is known as hardcoding credentials. If an attacker gains even limited access to the source code or configuration files, these hardcoded secrets can be immediately used to access other systems or services with high privileges. It’s like leaving a master key under the doormat. Effective secrets management is key here. This involves using dedicated systems to store and manage sensitive information, rotating credentials regularly, and ensuring that no secrets are ever embedded directly in code. This practice is a core part of secure development and application architecture.

Supply Chain Dependency Confusion

This tactic involves exploiting trust relationships within the software supply chain. Attackers might compromise a legitimate software component, library, or update from a trusted vendor. When an organization uses this compromised component, the attacker’s malicious code or access is effectively delivered through a trusted channel. It’s a bit like ordering a product from a reputable store, only to find out the product itself has been tampered with before it even reached the warehouse. This can lead to widespread compromise because many organizations might be using the same vulnerable dependency. Staying vigilant about the security of third-party components and conducting regular security assurance testing are vital steps to prevent this kind of attack.

Here’s a quick look at how these advanced tactics can be chained:

Initial Foothold: Gaining basic access through a less sophisticated method.
Discover Hardcoded Secrets: Finding embedded credentials in code or configurations.
Exploit Insecure API: Using discovered credentials to access an API with elevated permissions.
Compromise Dependency: Injecting malicious code into a software library used by the target.
Chain Completion: The compromised API or application now runs with higher privileges due to the exploited dependency.

Attackers are constantly looking for shortcuts. When they find hardcoded credentials or poorly secured APIs, it’s often a much easier path than trying to break through strong defenses directly. The supply chain adds another layer of complexity, as it leverages existing trust to deliver malicious payloads.

Defensive Strategies Against Privilege Escalation

Preventing privilege escalation isn’t about one magic bullet; it’s more like building a strong house with multiple layers of security. You can’t just rely on a good lock on the front door if the windows are wide open. So, what can we actually do to make it harder for attackers to climb the ladder?

Implementing Least Privilege Principles

This is a big one. The idea is simple: give people and systems only the access they absolutely need to do their jobs, and nothing more. Think of it like giving a contractor a key to your house, but only to the rooms they’re working in, and only for the time they need it. It drastically cuts down the potential damage if an account gets compromised. We need to regularly check who has what access and trim it back if it’s no longer necessary. This is a core part of managing insider risk, whether that’s accidental or intentional. Effective account provisioning is key here, making sure we’re not handing out too much power from the start.

Robust Patch Management and Vulnerability Remediation

Attackers love to exploit known weaknesses in software. If you’re not patching your systems regularly, you’re basically leaving the back door unlocked. It sounds obvious, but keeping everything updated is a constant battle. This means not just your operating systems, but all the applications, plugins, and libraries you use. Prioritizing which patches to apply can be tricky, but focusing on critical vulnerabilities that could lead to privilege escalation should be top of the list. It’s about closing those obvious holes before someone else finds them.

Enforcing Strong Access Controls

This goes hand-in-hand with least privilege. We need clear rules about who can access what, and we need to enforce them. This includes things like strong passwords, multi-factor authentication (MFA) everywhere possible, and role-based access control (RBAC). RBAC helps group users by their job functions, making it easier to manage permissions consistently. We also need to pay attention to how accounts are provisioned and deprovisioned. When someone leaves the company or changes roles, their access needs to be updated immediately. It’s a continuous process, not a one-time setup. Managing insider risk relies heavily on these controls.

The goal is to create a security environment where even if one part fails, the whole system doesn’t collapse. It’s about building resilience through layered defenses and constant vigilance, making the attacker’s job as difficult and time-consuming as possible.

Detection and Monitoring for Escalation Attempts

Keeping an eye on what’s happening within your systems is super important, especially when it comes to spotting privilege escalation. It’s not always obvious when someone is trying to get more access than they should. You need to have good systems in place to catch these activities before they cause real damage. Think of it like having security cameras and motion detectors all over your building – you want to know if someone is trying to break into a restricted area.

Monitoring Privilege Changes and Anomalous Activity

One of the most direct ways to detect privilege escalation is by watching for changes in user or system privileges. Anytime a user’s access rights are increased, or a system service starts acting with higher permissions, it should raise a flag. This isn’t just about looking at who got promoted; it’s about tracking every change. We’re talking about logging when permissions are granted, modified, or revoked. The goal is to establish a baseline of normal activity and then flag anything that deviates significantly. This could include things like a regular user account suddenly trying to access administrative tools or a service account performing actions outside its usual scope. Tools that track these changes can help identify suspicious patterns that might otherwise go unnoticed. Keeping a close watch on these events is key to preventing attackers from moving deeper into your network. You can find more on how to do this by analyzing access patterns.

Leveraging User Behavior Analytics

Beyond just tracking direct privilege changes, looking at user behavior can reveal a lot. User Behavior Analytics (UBA) tools help by building a profile of what normal user activity looks like. This includes things like login times, locations, the types of files accessed, and the applications used. When a user suddenly starts logging in at odd hours, accessing sensitive data they’ve never touched before, or attempting to run unusual commands, UBA can flag this as anomalous. These deviations might indicate that an account has been compromised and is being used for privilege escalation. It’s about spotting the subtle signs that something isn’t right, even if no direct privilege change has occurred yet. This approach is particularly useful for detecting insider threats or compromised accounts that are being used carefully.

Security Telemetry and Event Correlation

Pulling together information from various sources, known as security telemetry, is vital. This means collecting logs from servers, network devices, applications, and endpoints. Then, you need to correlate these events. For example, a failed login attempt on one server, followed by a successful login from a different location on another system shortly after, might be a sign of credential stuffing or an attempt to move laterally after gaining some level of access. By correlating events across different parts of your infrastructure, you can build a clearer picture of an attack in progress. This helps connect the dots between seemingly unrelated activities, making it easier to spot a coordinated effort to escalate privileges. A good Security Information and Event Management (SIEM) system is often used for this purpose, helping to sift through the noise and highlight significant security events. This kind of detailed monitoring is a core part of enforcing least privilege effectively.

Incident Response and Recovery from Escalation

When privilege escalation happens, it’s not the end of the world, but you definitely need to act fast. The first thing is to figure out what happened and stop it from spreading. This means isolating any systems that seem compromised. You don’t want the attacker to jump from one machine to another, right? So, think about cutting off network access for those specific systems or disabling any accounts that look suspicious. It’s about limiting the damage before it gets worse.

Containment and Isolation of Compromised Systems

When you suspect privilege escalation, the immediate goal is to contain the breach. This involves identifying which systems are affected and then separating them from the rest of your network. It’s like putting up a barrier to stop a fire from spreading. You might disable network interfaces on the affected machines or block specific IP addresses that seem to be involved. The idea is to prevent the attacker from using that foothold to move further or access more sensitive data. This initial step is critical for limiting the scope of the incident.

Eradication of Malicious Access

After you’ve contained the problem, you need to get rid of whatever the attacker used to gain that extra access. This could mean removing malware, patching the software vulnerability they exploited, or resetting any compromised credentials. If they used a weak configuration, you’ll need to fix that too. The key here is to make sure the attacker can’t just hop back in using the same method. It’s a thorough cleanup to remove the threat completely.

Auditing Permissions and System Hardening

Once the immediate threat is gone, it’s time to look at why this happened in the first place. You’ll want to audit all user and system permissions. Are there accounts with way more access than they actually need? This is where the principle of least privilege comes in – making sure everyone and everything only has the access required for its job. You should also harden your systems. This means reviewing configurations, disabling unnecessary services, and making sure all software is up-to-date. It’s about making your systems tougher targets for future attacks. This review process is a key part of lessons learned and improving your security posture.

Future Trends in Privilege Escalation

The landscape of privilege escalation is constantly shifting, driven by new technologies and evolving attacker methods. As organizations adopt more sophisticated infrastructures, attackers are finding new avenues to exploit.

Cloud-Native Service Exploitation

Cloud environments, while offering flexibility, introduce unique challenges. Attackers are increasingly targeting misconfigurations in cloud services, such as improperly secured storage buckets or overly permissive IAM roles. Exploiting these weaknesses can grant unauthorized access to sensitive data or allow for the execution of malicious code within the cloud infrastructure. The dynamic nature of cloud resources means that security configurations can change rapidly, creating windows of opportunity for attackers. Understanding cloud security models and implementing robust access governance is key here. For instance, ensuring that services only have the permissions they absolutely need, following the least privilege principle, can significantly reduce the attack surface.

Container and Identity-Based System Targets

Containers, like Docker, have become a staple for application deployment. However, vulnerabilities within container runtimes or misconfigurations in orchestration platforms (like Kubernetes) can be exploited. Attackers might escape a container to gain access to the host system or other containers. Similarly, identity-based systems, which are central to modern authentication and authorization, are becoming prime targets. Compromising identity providers or exploiting weaknesses in single sign-on (SSO) solutions can give attackers broad access across an organization’s digital assets. This often involves sophisticated credential stuffing or token manipulation techniques.

AI-Driven Attack Sophistication

Artificial intelligence is not just a tool for defenders; attackers are also integrating AI into their operations. This can manifest in several ways. AI can be used to automate the discovery of vulnerabilities at scale, analyze vast amounts of data to identify optimal targets, or even generate highly convincing phishing campaigns. For privilege escalation, AI could potentially be used to predict the most likely paths to elevated access within a network based on observed patterns. This makes detecting and responding to these advanced threats more challenging, requiring equally sophisticated, AI-powered defense mechanisms. The ability to perform data segmentation effectively becomes even more important when dealing with AI-driven threats that can rapidly identify and target valuable information.

Wrapping Up

So, we’ve walked through how attackers can climb the ladder of system access, starting small and ending up with a lot of control. It’s not just about finding one weak spot; it’s about putting pieces together, like a puzzle, to get where they want to go. Keeping systems secure means staying on top of updates, making sure permissions are tight, and watching for weird activity. The bad guys are always looking for new ways in, especially with cloud stuff and how we manage who gets to do what. Staying ahead means constantly learning and adapting our defenses, because if we don’t, we’re just making it easier for them.

Frequently Asked Questions

What is privilege escalation?

Imagine you have a key to your house, but not to the safe inside. Privilege escalation is like a hacker finding a way to get the safe key too, even though they weren’t supposed to. It means they get more powerful access than they started with, letting them control more of a computer system or network.

How do hackers do privilege escalation?

Hackers look for weak spots. They might find a bug in a program that lets them sneak in, or maybe a system is set up with easy-to-guess passwords. Sometimes, they trick people into clicking bad links or opening infected files. It’s all about finding shortcuts to get more control.

Why is privilege escalation dangerous for businesses?

If a hacker gets high-level access, they can steal important company secrets, mess up computer systems, or even shut down operations. This can cost a lot of money, damage the company’s reputation, and lead to legal trouble.

What’s the difference between initial access and privilege escalation?

Think of it like breaking into a building. Initial access is like getting through the front door, maybe by picking the lock. Privilege escalation is what happens *after* you’re inside, where you find a way to get into the manager’s office or a secure vault, which requires more effort and higher-level access.

How can companies stop hackers from escalating privileges?

Companies can make it harder for hackers by giving employees only the access they absolutely need for their jobs (this is called ‘least privilege’). They also need to keep software updated to fix security holes and use strong passwords and security measures.

What is ‘lateral movement’ in hacking?

Once a hacker has escalated their privileges on one computer, they might use that power to jump to other computers on the same network. This is called lateral movement, like moving from room to room in a building after getting into the main office.

Are cloud services safe from privilege escalation?

Cloud services can also be targets. Hackers can look for weak settings in cloud accounts or find flaws in how different cloud services talk to each other. It’s important to secure cloud environments just as carefully as regular computer systems.

What should a company do if they think privilege escalation has happened?

If a company suspects this, they need to act fast. They should try to stop the hacker from accessing more systems, figure out how the hack happened, fix the security problem, and then get everything back to normal. It’s like putting out a fire and then repairing the damage.
