Top Malware Reported in the Last 24 Hours

PirateMatryoshka malware
Researchers have detected a new strain of malware named PirateMatryoshka. The malware is distributed via The Pirate Bay (TPB) torrent tracker site. The trojan comes laden with hidden spyware packages. Once installed, the malware downloads a swathe of Potentially Unwanted Programs (PUP), spyware and adware. This slows down the PCs while wasting the system resources and spying on victims. 

PINCHY SPIDER distributes GandCrab ransomware
PINCHY SPIDER threat actor group has been found deploying GandCrab ransomware to target enterprises in a new attack campaign named ‘Big Game Hunting’. Researchers discovered that the group is also behind the development of GandCrab, which has been active since January 2018. The group sells access to use the ransomware under a partnership program with a limited number of accounts. 

New CryptoMix Clop ransomware variant
A new variant of CryptoMix Clop ransomware has been detected by researchers recently. The malware variant has been designed to target the entire network instead of individual computers. It is distributed via executables that have been code-signed with a digital signature. Once executed, the ransomware begins its infection process by terminating various Windows services and processes.   

Three prolific trojans
Researchers have reported that Emotet, LokiBot and TrickBot are the three trojans that wreaked havoc last year. During November and December, 2018, the researchers saw a surge in attack campaigns that leveraged Emotet. The malware was used in 45.9% of the attacks that occurred during the second half of the year. LokiBot represented 11.6% of observed samples in the last quarter of 2018. TrickBot represented 10.4% of observed attacks during the second half of 2018.  

Top Vulnerabilities Reported in the Last 24 Hours

Vulnerable UPnP-enabled devices

The San Francisco Division of the Federal Bureau of Investigation (FBI) is warning users about a SIM swapping fraud. The alert has come following the increase in such crimes. Cybercriminals are increasingly using the SIM swapping fraud to target victims with cryptocurrency and other digital currency accounts.
