Listen "Old malware returns in a new way."
Episode Synopsis
Jeremy Kennelly and Sulian Lebegue from Mandiant sit down with Dave to discuss their research "From RM3 to LDR4: URSNIF Leaves Banking Fraud Behind? One of the oldest and most successful banking fraud malwares, URSNIF, which caused an estimated “tens of millions of dollars in losses”, has been discovered by researchers to have been re-tooled into a generic backdoor, dubbed “LDR4”.
This new variant was first observed in June 2022. Mandiant researchers believe that the same threat actors who operated the RM3 variant of URSNIF are likely behind LDR4. They say "given the success and sophistication RM3 previously had, LDR4 could be a significantly dangerous variant—capable of distributing ransomware—that should be watched closely."
