Fake apps have become a popular channel for cybercriminals to drop malware and conduct malicious activities. Recently, researchers have found that there are more than 60 fake apps masquerading as the popular multiplayer game ‘Among Us’. Though the ultimate purpose of these fake apps is unknown, it is suspected that cybercriminals can use these apps to distribute malware to unsuspecting users.
Meanwhile, Windows 7 and Windows Server 2008 R2 operating systems have been detected to be affected by a zero-day vulnerability that can allow threat actors to gain a foothold on vulnerable systems. The vulnerability resides in two misconfigured registry keys for the RPC Endpoint Mapper and DNSCache services that are part of all Windows installations.
