Penn possibly hacked? Too soon to know the details, we'll have to see what their incident response team discovers. I have a few friends that received the referenced email, they are pretty bad.

Could be caused by a number of things, from a simple forgery to a complete compromise of their systems.
Dear Penn Community,
Fraudulent emails are currently being circulated that appear to come from a Penn Graduate School of Education account with the subject “We got hacked (Action Required)” or similar.

New: Videos show ICE/CBP agents are scanning peoples' faces on the street to verify citizenship. ICE has tool to instantly look up unprecedented number of databases with just a photo

“I’m an American citizen so leave me alone”

“Alright, we just got to verify that”

ICE and CBP Agents Are Scanning Peoples’ Faces on the Street To Verify Citizenship
Videos on social media show officers from ICE and CBP using facial recognition technology on people in the field. One expert described the practice as “pure dystopian creep.”

This is unbelievable - it would be a fireable offense at many companies. Intentionally bypassing national security protections and ensuring your communications cannot be monitored and logged?

Hegseth is a massive threat to national security. How the hell does he still have a job?!
Hegseth had an unsecured internet line set up in his office to connect to Signal, AP sources say
Defense Secretary Pete Hegseth had an internet connection that bypassed the Pentagon’s security protocols set up in his office to use the Signal messaging app on a personal computer.

Apparently we aren't going to talk about LockBit as a threat anymore. https://www.theguardian.com/us-news/2025/feb/28/trump-russia-hacking-cyber-security

Good going "cybersecurity isn't political" chucklenuts. You're cooked. We're cooked.
