"Angelov's group built a network of compromised computers (a 'botnet') through distribution of malware-infected files attached to spam emails. Angelov and his co-manager then monetized this botnet by selling access to individual compromised computers ('bots')."
"Between August 2018 and December 2019, TA551 provided the BitPaymer ransomware group with access to its botnet, allowing the e-crime gang to infect 72 U.S. corporations. This resulted in more than $14.17 million in extortion payments."
"The operators of the IcedID malware also paid Angelov's group over a million dollars to acquire access to the botnet in late 2019 or early 2020 and distribute ransomware, although the extent of the damage is currently not known."
Ilya Angelov, a 40-year-old Russian, was sentenced to two years in prison and fined $100,000 for managing a botnet used in ransomware attacks. He co-managed the cybercriminal group TA551 from 2017 to 2021, which built a network of compromised computers through malware-infected spam emails. The group sold access to these bots to other criminal organizations, facilitating ransomware extortion schemes that resulted in over $14 million in payments from U.S. corporations. Angelov's group also collaborated with other malware operators, further extending their criminal activities.
