Six Ransomware Gangs Claim 290+ New Victims in 2021, Potentially Reaping $45 Million for the Hackers

Colonial Pipeline, Quanta Computer and the City of Baltimore are all victims of very public ransomware attacks. With so many ransomware attack incidents being reported, it’s tempting to think you’re fully aware of just how pervasive this cyber threat has become. Think again. The ransomware attack victims we hear about publicly are a mere drop in the bucket compared to the actual number of successful cybercrime incidents. To illustrate this, eSentire’s research team, the Threat Response Unit (TRU), teamed up with Dark Web researcher Mike Mayes to track the current activity of the Ryuk/Conti, Sodin/REvil, CLOP, DoppelPaymer, DarkSide and Avaddon ransomware attack groups.

Ransomware Attack Report Findings 

TRU and Mayes found that these nefarious gangs have collectively compromised 292 new victim organizations between January 1 and April 31, 2021, according to the groups’ blog/leak sites and have potentially reaped just over $45 million in the past four months. TRU and Mayes also found that these cybercriminals have expanded their hit list to include manufacturers, transportation/logistics companies and construction firms in the U.S., Canada, South America, France and the U.K. Read this ransomware attack report to learn about the types and number of purported victim organizations and how to protect your company from a business-disrupting ransomware attack.
