“We stole 7TB of data, including confidential student and staff personal information, research data, medical data, police reports, drug test results, databases, HR documents, financial documents, etc. and more.”

The University of Manchester first revealed the attack on June 9, warning that data was likely stolen. No further details were provided about the attack, but BleepingComputer later learned it was ransomware.

During ransomware attacks, it is common for hackers to steal data before attempting to encrypt devices. This data is then used in a double extortion scheme, where threat actors threaten to release the data if a ransom is not paid.

No ransomware gang claimed responsibility for the attack on the University of Manchester, but if they stick to their threats, we’ll know more if any data is published on a data leak site.

BleepingComputer contacted the University of Manchester about these emails but received no response.
