Stop Building a 2003 SOC with AI: Local Context, Failure Modes and Your Path (Part 3)
In Part 1 of this series, we dumped a pile of uncomfortable questions on you and promised answers. In Part 2 of the series, we talked about why 1990s-2000s alert triage must die. The core thesis, if you recall: if you add AI agents into a legacy, swivel-chair SOC structure, you are essentially building a robotic…

CISA Red Team Compromised Two Critical Infrastructure Orgs, One Detected Nothing
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has published the results of two red team assessments it conducted simultaneously against two critical infrastructure organizations, using what it described as similar tradecraft while recording sharply different defensive outcomes.Both organizations were fully compromised at the domain level, and in both, the red team also First seen…

CISA Red Team Achieves Full Domain Compromise Across Critical Infrastructure Networks
CISA’s latest red team assessment shows how common failures in Active Directory, cloud identity, and SOC processes can turn a phishing foothold into an enterprise-wide compromise. The August 25 advisory contrasts two critical-infrastructure organizations: one missed the intrusion entirely, while the other contained initial access quickly but still exposed major identity and cloud security weaknesses.…

7-Zip Default Setting Lets Extracted Files Bypass Windows SmartScreen
7-Zip’s default configuration allows files extracted from internet-delivered archives to shed the Mark of the Web (MotW), meaning Windows SmartScreen never runs its reputation check and unsigned payloads can execute without a “Windows protected your PC” warning. That behavior, long treated as a red-team trick, is now formally recognized and tracked in multiple 7-Zip vulnerabilities,…

OpenSSL Fixes HollowByte Memory Exhaustion Bug
Okta disclosed HollowByte, an 11-byte OpenSSL flaw that lets remote attackers exhaust server memory and trigger denial-of-service attacks. Okta’s Red Team disclosed a denial-of-service vulnerability in OpenSSL they named HollowByte, and the attack payload is exactly 11 bytes. A remote, unauthenticated attacker sends that payload and the server allocates up to 131 KB of memory…
