On November 21st #ESETResearch detected and alerted @_CERT_UA of a wave of ransomware we named #RansomBoggs, deployed in multiple organizations in Ukraine🇺🇦. While the malware written in .NET is new, its deployment is similar to previous attacks attributed to #Sandworm. 1/9 
@_CERT_UA Its authors make multiple references to Monsters, Inc., the 2001 movie by Pixar. The ransom note (SullivanDecryptsYourFiles.txt) shows the authors impersonate James P. Sullivan, the main character of the movie, whose job is to scare kids. 2/9

We have become aware of a large #ICS/#SCADA malware project apparently conducted under a state contract on behalf of the Russian General Staff Main Intelligence Directorate (#GRU), Main Centre for Special Technologies (#GTsST), military unit 74455.
This military unit also known as #Sandworm is located at the GRU Ulitsa Kirova facility in the Khimki suburb of Moscow. In the past Sandworm has targeted ICS/SCADA, one of the most renowned being the #INDUSTROYER2 hacking attempt of a Ukrainian electrical substation in April 22.
The ongoing project is to cost more than 100 million rubles across three phases and undertaken by several technical defense contractors.
