Gold Ulrick Hackers Still in Action Despite Massive Conti Ransomware Leak

The notorious ransomware team acknowledged as Conti has continued its onslaught towards entities inspite of struggling a significant info leak of its possess earlier this year, in accordance to new research.

But following the cybercriminal cartel came out in assist of Russia more than its invasion of Ukraine in February, an nameless Ukrainian security researcher below the Twitter take care of ContiLeaks began leaking the source code as well as private discussions involving its customers, giving an unparalleled perception into the group’s workings.

The groups include Gold Blackburn (TrickBot and Diavol), Gold Crestwood (Emotet), Gold Mystic (LockBit), and Gold Swathmore (IcedID).

In fact, Intel 471’s technological checking of Emotet campaigns among December 25, 2021, and March 25, 2022, recognized that about a dozen Conti ransomware targets have been, in truth, victims of Emotet malspam attacks, highlighting how the two operations are intertwined.
