As ransomware gangs attempt to boost their illicit profits, the RagnarLocker ransomware gang has brought a new tactic to bear: installing a full virtual machine on victims' systems to hide their crypto-locking malware while it forcibly encrypts files, security firm Sophos warns.
Microsoft is warning Windows users about an ongoing "massive" COVID-19-themed phishing campaign that is attempting to install the NetSupport Manager on devices. Attackers can turn NetSupport into a remote access Trojan, or RAT.
A recent phishing campaign bypassed multifactor authentication protections within Microsoft Office 365 to steal users' credentials stored in the cloud or launch other attacks, according to the security firm Cofense.

More ransomware-wielding gangs are not just crypto-locking victims' systems, but also stealing and threatening to leak data unless they get their demanded bitcoin ransom payoff. A growing number of security experts believe the strategy is leading more victims to pay.
A sophisticated hacking group associated with the North Korean government that's been tied to a number of high-profile attacks, including WannaCry, is using three new malware variants, according to the U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency.
A recently discovered cyber-espionage toolkit called Ramsay is designed to infiltrate air-gapped networks to steal documents, take screenshots and compromise other devices, according to the security firm ESET.
