  1. Python Backdoor Threat Analysis Following an AI Deepfake Impersonation Campaign

    A sophisticated campaign linked to APT37 delivers Python-based backdoors through spear-phishing emails containing malicious LNK files disguised as legitimate documents. Attackers use themes including airline e-tickets, North Korea research invitations, and impersonation of defense and police officials to induce execution. The LNK files employ environment variable-based obfuscation techniques to download additional BAT files, which establish a Python runtime environment and execute compiled Python bytecode disguised with .cat extensions. The malware functions as a remote command execution backdoor, communicating with C2 servers to receive commands and exfiltrate results. Persistence is maintained through scheduled tasks executing at one-minute intervals. The campaign shows strong tactical similarities to previous APT37 operations, including infrastructure patterns, script obfuscation methods, and the abuse of legitimate tools.

  7. Throwback Thursday to back when I had a boardwalk on one of my beaches with festive carnival style booths all along it.

    I wonder if I should recreate something like this down in my shopping district again.

    Hmm.
