F5 Labs published its March 2026 CASI Leaderboard update, which is now dominated by OpenAI and Anthropic. Z.ai's GLM-5 performs well on price and capability but has a weak security posture (CASI 37.56 vs 96.61 for Claude Opus 4.6 and 92.58 for GPT-5.2). The report also spotlights Sugar-Coated Poison (SCP), a multi-turn technique that grad…

ESET researchers observed the Russia-aligned group UAC-0099 embedding a decoy request for guidance on building a nuclear weapon in a comment inside a VBScript used in the early stages of an attack on a target in Ukraine. The comment was meant to trigger the safety guardrails of an LLM-powered code scanner so that it stops inspecting the f…

The backdoor has replaced SparrowDoor as the group's main implant. From mid-2025 into 2026, about 90% of the group's targets in ESET telemetry were in Latin America, mostly governmental e…
ESET analysis describes how modern phishing and social engineering have shed the classic tells (poor grammar, suspicious URLs, crude login pages) and increasingly target live sessions and authentication tokens rather than passwords. Cybercrime-as-a-service phishing kits and AI tooling lower the cost of tailored, rapport-building lures. Ac…
A modular phishing campaign targets YouTube creators with personalized sponsorship offers from fake brand representatives.

TrustedSec analyzed a multi-stage malware loader that starts as obfuscated Python bytecode (.pyc, CPython 3.13) and ends in an encrypted .NET payload. The chain layers Kramer Python obfuscation, two Donut shellcode layers and a laZzzy shellcode-loader PE, so a signature for any single format misses the others. The author unpacked it with …
