The University of Illinois Chicago (UIC) said it recently found a ransomware attack on its College of Medicine, The Record reported on 5 October. Ransomware locks files until victims pay. A UIC spokesperson told Recorded Future News that hackers also stole some information from the college's servers. The university said all affected systems are restored and its main network was not affected. It said patient care at UI Health was not affected. It told law enforcement and will notify anyone whose information was stolen.
UIC has not said what was taken. It is still checking whether personal, research or academic information was compromised. The report gives no attack date. A gang called Booba claimed the attack last week and said it took 344 gigabytes. SentinelOne's Brett Williams said Booba appears to be a rebrand of Frag ransomware.
UIC says systems are back, yet it also says data was stolen. As general context, not a claim about UIC: some attackers copy files first, then lock them. Backups fix the outage, but cannot recall copies already taken. Ask whether your tools would flag large data leaving your network. Ask whether you know what each server holds. Without both, you cannot say what was exposed.
