Overview
- The University of Pennsylvania said it has referred the incident to the FBI and is working with law enforcement and external technical experts.
 - School officials described the messages as fraudulent and highly offensive, and BleepingComputer traced their origin to Penn’s connect.upenn.edu on Salesforce Marketing Cloud.
 - An anonymous actor told BleepingComputer they used a compromised PennKey SSO to access VPN, Salesforce, Qlik, SAP, and SharePoint, and claimed they stole data on about 1.2 million people, a claim not independently verified.
 - The actor said they sent the mass email to roughly 700,000 recipients through Salesforce Marketing Cloud after other access was cut off.
 - The hacker published a 1.7‑GB archive allegedly taken from SharePoint and Box, while the FBI’s Philadelphia office declined public comment during the government shutdown.
