Also Worth Your Attention
New SynkLoader malware pushed in Microsoft Teams phishing campaign
Expel says the campaign uses Microsoft Teams messages to push a fake “PowerShell Cleaner” MSI from Azure, then drops a multi-language toolkit that installs persistence, opens a remote PowerShell shell, and displays a fake Windows 11 lock screen to capture credentials.
Why it matters: The attack abuses a collaboration channel users often trust more than email. When Teams chat delivers the payload and a fake lock screen harvests credentials, identity and endpoint controls have to catch it together.

Defending Against an Active Threat to Siemens S7 Series PLCs
CISA, NSA, FBI, DOE, and EPA say actors are actively targeting Siemens S7 PLCs by scanning for internet-exposed devices and using AI-assisted scripts with snap7 tooling to read or modify controller memory and ladder logic.
Why it matters: This is an OT intrusion-preparation warning, not routine patch guidance. It names real PLC families used across manufacturing, energy, water, chemical, food, and commercial facilities.

UAT-10147: Chinese-speaking adversary integrates agentic AI into post-compromise operations
Cisco Talos discovered a Chinese-speaking cybercrime group, tracked as UAT-10147, that targets many kinds of vulnerable web servers. This overview covers the countries affected, what BadIIS infections can do, the attack chain, and post-compromise tactics.
Why it matters: The useful shift is not the word "AI" alone. Offensive operators are using AI to speed up exploit refinement, troubleshooting, and persistence, which cuts the human effort needed for complex post-compromise work.
