In the context of an internationally coordinated operation against a ransomware group, the Zurich Public Prosecutor’s Office is leading criminal proceedings against an accused person. At the same time, cyber investigators of the Zurich Cantonal Police have been intensively analysing the data storage devices seized from that person in the past months. This analysis has revealed numerous private keys. They enable the aggrieved companies to recover their encrypted data.

Webworm: Espionage Attackers Testing and Using Older Modified RATs
The attackers are working on a number of malware threats, some of which have been used in attacks while others are in pre-deployment or testing stages. Symantec, by Broadcom Software, has gained insight into the current activities of a group we call Webworm. The group has developed customized versions of three older remote access Trojans (RATs), including Trochilus, Gh0st RAT, and 9002 RAT. At least one of the indicators of compromise (IOCs) observed by Symantec was used in an attack against an IT service provider operating in multiple Asian countries, while others appear to be in pre-deployment or testing stages.

RedLine spreads through ads for cheats and cracks on YouTube
An unusual malicious bundle (a collection of malicious programs distributed in the form of a single installation file, self-extracting archive or other file with installer-type functionality) recently caught our eye. Its main payload is the widespread RedLine stealer. Discovered in March 2020, RedLine is currently one of the most common Trojans used to steal passwords and credentials from browsers, FTP clients and desktop messengers. It is openly available on underground hacker forums for just a few hundred dollars, a relatively small price tag for malware.
