The Donut Leaks Ransomware Gang Attacks GGW Group

The Donut Leaks ransomware gang has attacked GGW Group. GGW Group is a group of insurance brokers headquartered in Hamburg, Germany. Donut Leaks posted GGW Group to its data leak site on September 14th but provided no further details.

Researchers first identified the Donut Leaks extortion group when an employee of one of the victims revealed that the corporate network had been breached by threat actors seeking to steal data. After successfully pilfering the data, the threat actors proceeded to email the victims' business partners and employees with URLs to their Tor extortion sites.

Tor Extortion Sites

These Tor sites consist of two components: a shaming blog and a data storage site. Visitors to these sites can freely browse and download all the stolen and leaked data. The stolen data storage server operates using the File Browser application, enabling visitors to navigate through the stolen data categorized by victim.

Method of Operation

It remains unclear whether the threat actors deploy ransomware during their network breaches or if they solely operate as a data extortion group. However, Sheppard Robson, a victim, did disclose that their recent attack involved ransomware. Researchers also believe that Donut Leaks could be an offshoot of the Ragnar Locker and Hive ransomware gangs.
