A new variant of MegaCortex ransomware making its way across the U.S. and Europe has been recast as a self-executing menace that doesn’t require a password and is aimed at enterprises, according to a technical analysis released by researchers at Accenture iDefense.

“The disadvantage of the first version was that actors had to run the ransomware manually or risk of leaking the password. This prevented global distribution of the ransomware,” Accenture said. “The MegaCortex Version 2 author has updated the ransomware to remove these disadvantages and redesigned the ransomware to self-execute.”

“It seems this threat actor has done its homework regarding which business model works best,” said Mounir Hahad, who heads Juniper Networks Threat Labs. “It has learned from the infamous SamSam group that also delivers ransomware manually after infiltrating an organization.”
