You know, when we talk about cyber stuff, there's a lot of jargon. But one thing that keeps popping up is 'payload staging techniques.' It sounds complicated, right? Basically, it's how bad actors get their malicious code onto a system and get it ready to do its dirty work. Think of it like setting up a base camp before climbing a mountain – you need to get your gear and supplies in place first. This article is going to break down what that really means, how it's done, and why it matters for keeping our digital stuff safe. We'll look at the different ways this happens, from sneaky tricks to using everyday tools against us. Key Takeaways Payload staging is the process of getting malicious code ready to execute on a target system, often involving multiple steps to avoid detection. Attackers use various methods for staging, including exploiting compromised systems, cloud services, or even legitimate infrastructure. Initial access for staging often comes through phishing, exploiting software flaws, or stealing login details. Once staged, payloads are used to establish persistence, move around a network, and evade security measures. Defending against payload staging requires a layered approach, including endpoint security, network analysis, and behavioral monitoring. Understanding Payload Staging Techniques Payload staging is a method used by attackers to break down their malicious software, or payload, into smaller, more manageable pieces. Instead of trying to send the entire malicious package at once, which might be detected or fail, attackers use staging to deliver it in stages. Think of it like sending a large item in multiple boxes; each box is easier to handle and less suspicious on its own. Definition of Payload Staging Payload staging involves dividing a malicious payload into multiple components. The initial component, often called a stager, is small and designed to be easily delivered and executed. Once active, the stager's job is to download and assemble the remaining parts of the payload from a remote location. This approach helps bypass security measures that might flag larger, more complex files. The Role of Staging in Attack Lifecycles Staging plays a significant role throughout the attack lifecycle. After gaining initial access, attackers often use staging to deploy their main payload without directly transferring it. This is especially useful when the initial access vector is limited in size or capability. The stager can then establish persistence, download additional tools, or prepare the system for further actions like privilege escalation or lateral movement. It's a way to maintain a foothold and gradually build up the attacker's presence. Key Objectives of Payload Staging There are several reasons why attackers opt for staging: Evasion: Smaller, less complex initial payloads are less likely to be detected by antivirus software or intrusion detection systems. Flexibility: Attackers can change or update the main payload remotely without needing to re-exploit the initial access point. Resourcefulness: It allows attackers to operate in environments with limited bandwidth or strict network controls. Stealth: By downloading components from seemingly legitimate sources or using multiple hops, the staging process can be harder to trace back to the attacker. The effectiveness of staging relies heavily on the attacker's ability to control the remote server hosting the payload components and to ensure the stager can reliably connect to it. If the staging server is taken down or becomes inaccessible, the attack can be halted before the full payload is deployed. Common Payload Staging Methodologies Payload staging is all about setting up the next phase of an attack. It's not just about getting the initial foothold; it's about making sure the rest of the operation can run smoothly and effectively. Attackers use various methods to stage their payloads, often choosing techniques that blend in or exploit existing trust. Leveraging Compromised Systems One common approach is to use systems that have already been taken over. Think of it like using a captured base to launch further operations. An attacker might gain access to a server or even a user's workstation and then use that system as a launchpad. This is particularly effective because the malicious activity originates from a seemingly legitimate, albeit compromised, internal source. This can make detection harder, as the traffic might look like normal internal network activity. It also bypasses many perimeter defenses that are focused on external threats. The attacker can then host their next-stage payload on this compromised system, ready to be downloaded or executed by another compromised machine or a newly exploited vulnerability. Utilizing Cloud Services for Staging Cloud platforms offer a flexible and often cost-effective way for attackers to stage payloads. Services like cloud storage (e.g., S3 buckets), file-sharing platforms, or even compromised web hosting accounts can be used. The advantage here is scalability and accessibility. Attackers can spin up resources quickly and access them from anywhere. They might set up a seemingly innocuous website or a public cloud storage bucket to host their malicious files. These resources can be configured to look legitimate, making them harder to flag. The use of cloud services also allows attackers to distribute their staging infrastructure across multiple providers, making it more resilient to takedowns. This method is often seen in campaigns that require a broad reach or a distributed infrastructure. Exploiting Legitimate Infrastructure This is where things get really sneaky. Instead of setting up their own infrastructure or using compromised systems, attackers might abuse legitimate services that are already in place. This could involve using services like pastebin sites, code repositories, or even legitimate file-sharing services in ways they weren't intended. For example, a malicious script could be hidden within a public code repository, or a payload could be disguised as a legitimate file shared via a cloud storage link. The key here is that the infrastructure itself is trusted, making the malicious content hosted on it less likely to be immediately suspicious. This technique relies heavily on the inherent trust placed in these platforms and can be quite effective at bypassing security controls that might block known malicious domains or IP addresses. It's a way to blend in with normal internet traffic and activity, making detection a significant challenge. Understanding attack lifecycles is key to spotting these methods. Techniques for Initial Access and Staging Getting into a system is just the first step for an attacker. After that, they need to get their actual malicious code, the payload, onto the target system in a way that works and doesn't get caught right away. This is where initial access and staging techniques come into play. It's not just about breaking in; it's about setting up shop for whatever comes next. Phishing and Social Engineering Vectors Phishing is still a big one. Attackers send emails, messages, or create fake websites that look legitimate to trick people into clicking malicious links or opening infected attachments. Think of those emails that look like they're from your bank or a popular online store, asking you to 'verify your account' or 'claim a prize'. When you click the link, you might download malware, or it could take you to a fake login page to steal your credentials. Social engineering is broader, using psychological manipulation to get people to divulge information or perform actions they shouldn't. This could be a phone call pretending to be IT support, asking for your password to 'fix an issue'. Spear Phishing: Highly targeted phishing attacks aimed at specific individuals or organizations. Whaling: A type of spear phishing specifically targeting senior executives. Vishing: Voice phishing, using phone calls to trick victims. Smishing: SMS phishing, using text messages. Exploiting Software Vulnerabilities Software, no matter how well-tested, can have flaws. Attackers actively look for these weaknesses, known as vulnerabilities, in operating systems, web browsers, applications, or even network devices. If a vulnerability is known and a patch hasn't been applied, it's like leaving a door unlocked. Attackers can use 'exploit kits' or custom code to take advantage of these flaws, allowing them to run commands on the target system without any user interaction. This is a common way to get initial access, especially in environments where systems aren't kept up-to-date. Vulnerability Type Example Attack Vector Unpatched OS Remote code execution via a known Windows flaw Browser Exploit Drive-by download from a compromised website Web Application Flaw SQL injection to gain database access Outdated Plugin/Extension Exploiting a vulnerable Flash Player or Java applet Credential Harvesting and Reuse Sometimes, the easiest way in isn't through complex technical exploits but by getting hold of valid login details. Attackers might harvest credentials through phishing, by using keyloggers, or by finding them in leaked databases. Once they have a username and password, they can try to use it on other systems, a technique called credential stuffing. If an organization reuses passwords or uses weak ones, this can be a very effective way to gain access. They might also try to capture authentication tokens or use techniques like pass-the-hash to move around the network using stolen credentials without needing the actual password. Gaining access through stolen or weak credentials bypasses many technical defenses. It highlights the importance of strong authentication methods and user education about password security. Establishing Persistence with Staged Payloads Once an attacker has gained initial access and staged their payload, the next logical step is to ensure they can maintain access even if the system reboots or the initial exploit is discovered. This is where persistence mechanisms come into play. Attackers aim to make their presence difficult to remove, allowing them to return to the compromised system at their convenience. Registry Run Keys and Scheduled Tasks One of the most common ways to achieve persistence is by modifying the Windows Registry or creating scheduled tasks. Attackers can add entries to specific registry keys, such as Run or RunOnce, which are executed automatically when a user logs in. Similarly, they can create scheduled tasks that run at specific intervals or upon system startup. Registry Run Keys: Entries in HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun or HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun execute programs upon user login. Scheduled Tasks: The Task Scheduler can be configured to launch executables, scripts, or commands at predefined times or system events. User Account Control (UAC) Bypass: Some methods might involve techniques to bypass UAC prompts, allowing malicious code to run with elevated privileges without user interaction. Service Creation and Manipulation Attackers can also create new services or manipulate existing ones to ensure their payload runs. Creating a new service allows the payload to start automatically with the operating system, often with system privileges. Alternatively, they might modify the properties of legitimate services to point to their malicious executable, effectively hijacking the service's execution. Manipulating services is a powerful technique because services are designed to run in the background and start automatically, making them ideal for maintaining stealthy persistence. WMI Event Subscriptions Windows Management Instrumentation (WMI) provides a robust framework for system management, and attackers can abuse it for persistence. By creating WMI event subscriptions, attackers can trigger malicious scripts or executables based on specific system events, such as system startup, user login, or even specific process activity. This method is often more stealthy than registry modifications or service creation, as WMI events can be harder to detect. The goal is to make the payload's execution as automatic and as difficult to trace as possible. Evasion and Stealth in Payload Staging Attackers want their staged payloads to stay hidden as long as possible. Getting detected early ruins their plans. Because of this, evasion and stealth are top priorities in most payload staging strategies. Here are some of the main ways attackers keep things secretive during each phase of staging. Obfuscation and Encryption Techniques Attackers will often use obfuscation and encryption to hide the real nature of their payloads. Obfuscation makes code harder to read or reverse-engineer, while encryption ensures that even if the payload is intercepted, its contents won't be immediately visible. Key tactics include: Packing or compressing executables with tools that change how code looks to scanners Encrypting payloads with custom algorithms so static detection fails Using code morphing: frequently changing the code structure with each deployment so it rarely looks the same When attackers encrypt or scramble their payloads, they’re betting that traditional security tools won’t dig deep enough to identify the real threat. Living Off The Land Binaries Instead of bringing their own malware, adversaries frequently use system-native tools to perform tasks, which is called "living off the land." This makes their activities look more like routine admin work. A few examples: Running PowerShell scripts for file downloads or command execution Using certutil or mshta to decode and launch payloads Leveraging built-in Windows commands (e.g., wmic, schtasks) to move or execute files This approach lowers the attacker’s profile and reduces the chance they’ll trip security alerts. Process Injection and Hollowing Process injection lets attackers run their malicious code inside a legitimate process. Process hollowing is a twist: attackers start a valid process, strip out its legitimate code, and replace it with their payload. This tricks monitoring tools that rely on process names or known binaries. Some common methods: DLL injection into trusted processes Replacing running process memory with malicious code (process hollowing) Using thread injection to execute small routines under the radar Technique Typical Goal Tool Examples DLL Injection Code execution Metasploit, Cobalt Strike Process Hollowing Stealth execution Donut, Cuckoo Thread Injection Small payload launch Meterpreter, Empire If defenders only look at process names or basic activity, these tricks work far too well. Attackers know most teams don’t look inside every running program. Staging for Lateral Movement Once an attacker has a foothold on one system, the next logical step is often to move around the network. This is where payload staging really comes into play for lateral movement. It's all about expanding their reach, finding valuable data, and maybe even grabbing more powerful access. Credential Dumping and Pass-the-Hash Attackers frequently try to steal credentials from the initial system. This can be done through various methods, like dumping password hashes from memory or the SAM database. Once they have these hashes, they can use techniques like Pass-the-Hash (PtH) or Pass-the-Ticket (PtT) to authenticate to other systems on the network without needing the actual passwords. It's like having a master key that works on multiple doors. Mimikatz is a well-known tool for extracting credentials and hashes from Windows systems. Techniques often involve accessing LSASS (Local Security Authority Subsystem Service) memory. Staged payloads might be used to execute these credential dumping tools remotely. Remote Service Exploitation Many systems have services running that can be exploited for remote access. Think about things like Windows Management Instrumentation (WMI), Server Message Block (SMB), or Remote Desktop Protocol (RDP). If these services are misconfigured or have known vulnerabilities, an attacker can use a staged payload to exploit them and gain access to another machine. This often requires knowing the network layout and which services are exposed. Commonly exploited services include: SMB (for file sharing and remote command execution) WMI (for remote administration and execution) RDP (for direct desktop access) WinRM (Windows Remote Management) Abuse of Trust Relationships Networks often have trust relationships between systems, users, and groups. Attackers look for ways to abuse these. For example, if a service account has administrative rights on multiple machines, compromising that account allows movement across all those systems. Similarly, exploiting trust between domain controllers or between different organizational units can open up new pathways. Understanding and mapping these trust relationships is key for attackers to move effectively. Attackers often map out the network topology and identify high-value targets or systems with broad access. They might look for domain administrator accounts, service accounts with excessive privileges, or systems that act as central hubs for other machines. The goal is to find the path of least resistance to the most valuable data or control. Technique Description Pass-the-Hash (PtH) Authenticating to a remote system using NTLM hashes instead of plaintext passwords. WMI Exploitation Using WMI to execute commands or transfer files on remote systems. Scheduled Task Creation Creating a scheduled task on a remote system to execute a payload. Service Creation/Control Creating or controlling Windows services on remote machines for execution. Tools and Technologies for Payload Staging Payload staging isn't just about dropping files onto a computer. Behind the scenes, there's a mix of tools and tech that let attackers move code securely, quietly, and reliably from one stage to the next. Let's break down the main tools used for this process and see how they end up playing a key role in both simple and advanced attacks. Custom Stagers and Frameworks Custom stagers are handmade tools or scripts designed to get a small bit of code (the "stager") running on a target system. Once there, the stager fetches the real payload—the more complex piece of malware or remote access tool. Offensive security frameworks like Metasploit, Cobalt Strike, and Sliver offer built-in stagers supporting various protocols and formats. The main benefits of custom stagers include: Flexibility for different environments (Windows, Linux, macOS) Support for multiple communication channels (HTTP/S, DNS, SMB) Ability to avoid standard antivirus detection Attackers may even tweak or obfuscate these stagers to beat signature-based security tools. Any custom stager has to be extremely small and simple—it can't do much except pull in the next stage without triggering alarms. Commercial Off-The-Shelf (COTS) Tools Not every payload staging step needs handmade code. Sometimes, attackers pick up legitimate, widely used software and turn it toward their own ends. Common examples of COTS tools used for staging include: Remote administration utilities (like PsExec, TeamViewer, or AnyDesk) File transfer solutions (WinSCP, Rclone) Cloud syncing apps (Dropbox client, Google Drive for desktop) Why do these tools work so well for attackers? Because organizations already depend on them for daily operations, making it less likely anyone will notice unusual use. Tool Original Purpose Attacker Use PsExec Remote command execution Deploy or execute payloads remotely WinSCP File transfer Move staged payloads between compromised hosts TeamViewer Remote desktop access Unnoticed payload delivery via live sessions Dropbox client Cloud file syncing Encrypted payload staging/distribution Open-Source Intelligence (OSINT) for Targeting OSINT doesn't install the malware for you, but it's a huge part of modern staging success. Attackers use freely available information to pick the best targets and choose the most effective tools for the job. This stage can be shockingly thorough: Collecting lists of software, services, and versions an organization uses (via job postings, support forums, company reports) Pinpointing which cloud services or remote management tools are exposed externally Harvesting leaked credentials or email addresses from data breaches Attackers armed with good OSINT know exactly where to drop their stagers—and which ones are least likely to get flagged. If your network includes containerized workloads or cloud-native tools, attackers will factor that into their staging choices, as keeping containers up to date and properly configured is discussed on Securing container environments. Summary: Modern payload staging combines custom malware, trusted software, and deep public reconnaissance. The most successful attackers mix all three, switching techniques as needed to stay below the radar. If defenders want a shot at stopping them, they need good visibility—not just on strange programs, but also on how normal tools are being used. Defensive Strategies Against Payload Staging When it comes to stopping attackers from staging their payloads, it’s not just about one magic bullet. You really need a layered approach, kind of like building a fortress with multiple walls and watchtowers. The goal is to make it as difficult as possible for them to get their malicious code into your systems and then move around. Endpoint Detection and Response (EDR) Think of EDR as your digital security guard on every computer and server. It's constantly watching for suspicious activity. This isn't just about spotting known viruses; EDR tools look for unusual behaviors. For example, if a program suddenly starts trying to access sensitive system files it normally wouldn't, or if it's making weird network connections, EDR can flag it. This kind of behavioral analysis is key to catching staged payloads before they can do real damage. It's about detecting the actions of the malware, not just its signature. Real-time monitoring of endpoint activities. Behavioral analysis to detect novel threats. Automated response capabilities, like isolating a compromised machine. EDR solutions are becoming increasingly important because attackers are getting smarter. They're not always using old, well-known malware. Instead, they're using custom tools or 'living off the land' techniques, which means they use legitimate system tools to carry out their attacks. EDR is designed to spot these kinds of evasive maneuvers. Network Traffic Analysis Your network is like the highway system for your data. You need to watch the traffic to see if anything out of the ordinary is happening. Network traffic analysis tools monitor the data flowing in and out of your network. They can spot unusual communication patterns, like a server trying to connect to a known malicious IP address or a sudden surge in data being sent to an unknown destination. This can indicate that a staged payload is trying to communicate with its command-and-control server or exfiltrate data. It’s about seeing the bigger picture of what’s happening across your entire network, not just on one machine. This is especially important for detecting Advanced Persistent Threats that often use subtle communication channels. Traffic Type Detection Focus Command & Control Unusual DNS queries, C2 server communication patterns Data Exfiltration Large outbound transfers, encrypted traffic anomalies Lateral Movement Internal scanning, unusual RDP/SMB activity Behavioral Monitoring and Anomaly Detection This is where you set a baseline for what 'normal' looks like in your environment and then watch for anything that deviates from that. Behavioral monitoring looks at user actions, system processes, and network connections over time. If a user account suddenly starts logging in at odd hours from a new location, or if a server process begins consuming excessive resources, these anomalies can be red flags. It's not about predefined rules as much as it is about spotting deviations that suggest something is wrong. This approach is particularly effective against zero-day threats or custom malware that hasn't been seen before. It helps catch those staged payloads that are designed to fly under the radar of traditional signature-based defenses. Advanced Payload Staging Considerations Supply Chain Compromise for Staging Attackers are getting pretty clever, and one way they're making things harder for defenders is by messing with the supply chain. This isn't just about software anymore; it's about anything that goes into building or running systems. Think about it: if an attacker can sneak something malicious into a piece of hardware before it even gets to you, or compromise a software update from a vendor you trust, that's a huge win for them. They can then use that compromised component or update to stage their payloads. It's like planting a bomb in the foundation of a building before it's even constructed. This makes detection incredibly difficult because the initial compromise happens way before the payload is ever deployed on your network. Defenders have to look way beyond their own network perimeters now. AI-Driven Payload Delivery Artificial intelligence is changing the game in a lot of fields, and unfortunately, cybersecurity is no exception. Attackers are starting to use AI to make their payload delivery smarter and more effective. This could mean using AI to figure out the best time to strike, or even to tailor the payload to a specific target based on gathered intelligence. Imagine an AI that can analyze network traffic patterns and then deploy a payload when defenses are weakest, or when a specific user is most likely to click on a malicious link. It's about making attacks more precise and harder to predict. The goal is to automate and optimize the entire staging and delivery process. Staging in Cloud-Native Environments Cloud-native environments, with their dynamic nature and reliance on APIs and microservices, present a whole new set of challenges and opportunities for payload staging. Attackers can exploit misconfigurations in cloud services, abuse identity and access management systems, or target the APIs that connect different parts of an application. Because these environments are designed to be flexible and scalable, it can be tough to keep track of everything. A payload staged within a container or a serverless function might be harder to spot than one on a traditional server. Plus, the sheer volume of data and the interconnectedness of services mean that a small compromise can quickly spread. Here's a quick look at how cloud environments can be exploited for staging: Misconfigured Cloud Storage: Attackers might use unsecured S3 buckets or similar services to host staging files. Compromised CI/CD Pipelines: Injecting malicious code or artifacts into the build and deployment process. Abuse of Serverless Functions: Using functions like AWS Lambda or Azure Functions as a temporary staging area. Container Escapes: Exploiting vulnerabilities in container orchestration platforms to gain access to the underlying host or other containers. The complexity and rapid evolution of cloud-native architectures mean that traditional security approaches often fall short. Defenders need to adopt cloud-specific security tools and strategies, focusing on continuous monitoring, automated policy enforcement, and a deep understanding of how cloud services interact. Legal and Compliance Implications Ensuring your organization is handling payload staging threats properly isn't just about technology—it's also about staying on the right side of the law. With constantly shifting regulations and a growing patchwork of standards worldwide, ignoring compliance can cause serious headaches. Compliance is more than a checklist; it's about reducing legal risk and maintaining operational trust. Let's break down the key compliance issues you need to consider. Regulatory Frameworks and Reporting Most sectors face strict regulatory requirements when it comes to data protection and incident response. These rules might look a little different depending on your industry, but some key standards include: GDPR (Europe) HIPAA (US healthcare) PCI DSS (payment card industry) NIST and ISO 27001 (across many others) Failing to report or mishandling a payload-related breach usually results in steep fines and regulatory action. Here’s a quick comparison: Framework Data Breach Reporting Penalties for Noncompliance GDPR 72 hours Up to 4% of annual global turnover HIPAA Without delay $100–$50,000 per violation PCI DSS ASAP Loss of merchant rights, heavy fines NIST/ISO Varies (best practice) Certifications, contract risk But it's not just about avoiding fines. Proper reporting builds trust with customers and stakeholders. Even the best technical controls can’t prevent the fallout from a compliance misstep—proactive documentation and openness are key to avoiding chaos. Evidence Preservation for Forensics When a security incident hits, it’s tempting to react immediately, but hasty actions can destroy vital evidence. Preserving evidence is a legal requirement in many places and supports forensic analysis and investigations. Here’s what organizations should have in place: Detailed logging and retention policies Chain-of-custody documentation for digital evidence Clear rules for system containment and eradication activities Without these, your organization could face legal trouble, compromised investigations, or loss of insurance coverage. Impact on Incident Response Planning A solid incident response plan isn't just about wiping out attackers—compliance shapes every step: Notification timelines must match legal requirements. Response decisions (such as paying a ransom or engaging third parties) often require legal review. All communications, especially with external bodies, must be documented and controlled. Incident response plans should be reviewed and tested regularly to account for: New laws or regulations Lessons learned from real or simulated breaches Changes in business operations Proper planning keeps you organized and less likely to make legal missteps during stressful events. To wrap up, compliance and legal awareness don’t guarantee attacks won’t happen, but ignoring them can turn a manageable breach into a business disaster. Preparation, documentation, and clear communication make all the difference. Wrapping Up Payload StagingSo, we've gone over a few ways attackers get their payloads where they need them to be. It's not always super fancy, sometimes it's just about finding an open door or tricking someone. Keeping systems updated, watching what's happening on the network, and making sure only the right people have access are big parts of stopping this. It’s a constant game of cat and mouse, and staying on top of these staging techniques helps us build better defenses. Remember, a lot of these attacks rely on simple mistakes or overlooked systems, so good basic security hygiene really does go a long way. Frequently Asked Questions What is payload staging?Payload staging is like setting up a hidden base camp before a big climb. In computer security, it means an attacker first gets a small piece of code onto a target system. This small piece, called a stager, then downloads the main, bigger malicious program (the payload) from a safe place the attacker controls. It's a way to deliver the main attack without directly sending the whole thing at once, making it sneakier. Why do attackers use staging?Attackers use staging for a few good reasons. It helps them hide their main attack, bypass security systems that might block large files, and allows them to update the main attack later without having to break in again. Think of it as a way to be more flexible and less obvious when they're trying to cause trouble. How do attackers get the first piece (the stager) onto a computer?They use different tricks! Sometimes they send emails with bad links or attachments (phishing). Other times, they find weak spots in software that haven't been fixed yet. They might also trick people into giving them passwords or use passwords they've already stolen from other places. What happens after the stager downloads the main payload?Once the main payload is on the computer, the attacker can do many things. They might try to stay hidden on the system for a long time (persistence), move to other computers on the same network (lateral movement), steal information, or even lock up the computer and demand money (ransomware). How do attackers try to avoid being detected?They use clever tricks like scrambling their code (obfuscation) so it's hard to read, using normal computer programs to do bad things (living off the land), or hiding their malicious code inside other running programs. The goal is to blend in and not look suspicious. Can attackers use cloud services for staging?Yes, they absolutely can! Attackers might use cloud storage or websites to host their payloads. This is because cloud services are common and often trusted, making it harder for security systems to block them. Plus, they can easily access and manage their hidden files from anywhere. What are some ways to defend against payload staging?Defending against this involves a few layers. Keeping software updated is super important to fix the weak spots attackers use. Using security software that watches for strange behavior on computers and networks helps catch them. Also, teaching people to be careful about suspicious emails and links is a big help. Does staging make attacks more dangerous?Staging can make attacks more dangerous because it often means the attacker has already found a way in and is setting up for a more significant action. By breaking the attack into steps, they can bypass initial defenses and make it harder to track what they're really trying to achieve.
