DonutLeaks Ransomware Gang Attacks Sidock

The DonutLeaks ransomware gang has attacked Sidock. Sidock is a full-service multi discipline firm that focuses on engineering and civil planning. It is headquartered in Michigan, USA. DonutLeaks posted Sidock to its data leak site on October 21st, claiming to have stolen credit card details, bills, and SSNs.

Identification of DonutLeaks

Researchers first identified the DonutLeaks 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.

The 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.

Operational Tactics

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 DonutLeaks could be an offshoot of the RagnarLocker and Hive ransomware gangs.

Recent Ransomware Attacks

The Recent Ransomware Attacks (RRA) site acts as a watchtower, providing you with near real-time ransomware tracking of attacks, groups and their victims. Given threat actors’ overarching, lucrative success so far, ransomware attacks have become the most ubiquitous, and financially and informationally impactful cyber threat to businesses and organizations today.

The site’s data is generated based on hosting choices of real-world threat actors, and a handful of other trackers. While sanitization efforts have been taken, we cannot guarantee 100% accuracy of the data. Attack updates will be made as source data is reported by reputable sources. By viewing, accessing, or using RRA you acknowledge you are doing so at your own risk.
