Cisco warns of critical remote execution flaws in small business VPN routers from ZDNet

This poses some big risks for small businesses using a number of routers, especially since some are considered end-of-life for support and won’t get patches. Flaws are in the web management interface. Cisco released 3 security advisories yesterday. Over the past couple years, nation state adversaries have been hunting unpatched routers and using them in weaponized botnets. So check yours and patch 😇

Darkside Ransomware hits Electric Utility in Brazil, uses CyberArk from Bleeping Computer

I am seeing more utilities and major manufacturing as targets in the big game hunting of extortionist ransomware attacks. Two Brazilian state-owned electric companies just got hit. One of those, Copel, was hit by Darkside ransomware operators who stole 1000 GB of data, with critical and private info on networks, backups etc.

Of note is they got in by accessing Copel’s CyberArk privileged access management solution where they – sit down – “exfiltrated plaintext passwords across Copel’s local and internet infrastructure.” Wait, there’s more. Darkside says they exfiltrated AD data too. So much could go wrong 😱
