Show ▼
A credential-themed ZIP/LNK delivery campaign is using obfuscated PowerShell to fetch DLL payloads, creating a stealthy foothold risk for management users. The lures promise passport scans and payment records to encourage clicks. The chain then executes the payload through rundll32.exe and shifts files when it detects antivirus processes.

BlackPoint advisory on credential-themed ZIP/LNK PowerShell delivery campaign
Initial DisclosureBlackPoint describes a campaign using credential-themed ZIP archives with malicious .lnk files that quietly launch obfuscated PowerShell, download DLL payloads disguised as .ppt files, and execute them with rundll32.exe while targeting management vertical users. The advisory notes that the dropper checks for common antivirus processes, switches payload files for stealth, and recommends blocking or detonating LNK files in archives, enforcing Mark of the Web, restricting rundll32 usage, and instrumenting PowerShell with script block logging, transcription, AMSI, and TLS inspection.
