New research revealed that the SamSam ransomware had extorted nearly $6 million from its victims since December 2015, when the cyber gang behind the ransomware started distributing the malware in the wild.
Researchers at Sophos have tracked Bitcoin addresses owned by the attackers mentioned on ransom notes of each SamSam version and found the attackers have received more than $5.9 million from just 233 victims, and their profits are still on the rise, netting around $300,000 per month.
Attackers first compromise the RDP on a targeted system—either by conducting brute force attack or using stolen credentials purchased from the dark web—and then attempt to strategically deploy SamSam ransomware throughout the network by exploiting vulnerabilities in other systems.
