An "Aggressive" advanced persistent threat group known as SideWinder has been linked to over 1,000 new attacks since April 2020. "Some of the main characteristics of this threat actor that make it stand out among the others, are the sheer number, high frequency and persistence of their attacks and the large collection of encrypted and obfuscated malicious components used in their operations," cybersecurity firm Kaspersky said in a report that was presented at Black Hat Asia this month.
The gathered credentials are then exfiltrated and sold on Russian cybercrime forums for prices ranging from a few to thousands of U.S. dollars.
