Cybersecurity researchers have flagged a new macOS information stealer called PamStealer that employs a series of clever tricks to infect systems and siphon sensitive data. The stealer, discovered by Jamf Threat Labs, is distributed as a compiled AppleScript (.scpt) file impersonating Maccy, a legitimate open-source clipboard manager. It has been codenamed PamStealer owing to its ability to

A now-patched guardrail bypass in ChatGPT that could be exploited through a Local File Inclusion (LFI) vulnerability via its file download mechanism. This incident underscores how logic flaws in large language model (LLM) workflows, particularly concerning temporary file handling and access controls, can create exploitable weaknesses, even in sandboxed environments. ChatGPT Guardrail Bypass Vulnerability The […]

Hackers are using compromised websites and a deceptive transcript.pdf.js lure to deliver PureLog Stealer through a layered, fileless infection chain that leans heavily on PowerShell, trusted cloud infrastructure, and in-memory execution. The campaign, described in the attached research, shows how modern stealers increasingly rely on social engineering and living-off-the-land techniques rather than noisy malware binaries. […]

SharkLoader, used by an intrusion cluster tracked as StrikeShark to deliver Cobalt Strike Beacon entirely in memory across a wide international footprint. The campaign combines opportunistic exploitation of exposed internet-facing infrastructure with custom droppers disguised as trusted installers to establish initial access, then relies on layered, memory-only execution techniques and “Perfect DLL Hijacking” to minimize […]
