Ssisab-004.7z [ EXCLUSIVE 2024 ]

: Mentions of C:\windows\system32\kerne132.dll (note the "1" replacing the "l"), which is a common DLL hijacking technique.

: Upon execution, the malware typically copies itself to the system32 folder under a masked name to ensure it runs every time the computer boots.

: The file frequently imports CreateProcess and Sleep , indicating it likely spawns a persistent background process. 3. Dynamic Analysis (Execution) SSIsab-004.7z

The file is an encrypted archive typically used in educational malware analysis labs and cybersecurity competitions (such as CTFs). It contains a known malicious sample (often a Windows executable) designed to teach students how to perform basic static and dynamic analysis. Laboratory Analysis Write-up: SSIsab-004 1. File Identification and Integrity

The sample in SSIsab-004.7z serves as a textbook example of a . It establishes persistence on the host and waits for instructions from a remote server. : Mentions of C:\windows\system32\kerne132

Modification of registry keys (e.g., HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run ). 4. Conclusion and Mitigation

: The malware attempts to beacon out to a hardcoded domain. If the domain is unreachable, it may enter a "sleep" state to avoid detection. Host-Based Indicators : Creation of a new service. Laboratory Analysis Write-up: SSIsab-004 1

Static analysis is performed without executing the code to observe its structure and potential capabilities.
