New ransomware groups have sprung into action to wreak havoc across multiple organizations. One of these is tracked as Black Basta that infiltrated at least a dozen companies in a matter of weeks. Another newly found Onyx ransomware also managed to hit six organizations by destroying their large files instead of encrypting them. In another threat, RedLine Stealer resurfaced in a fresh RIG exploit kit campaign targeting a vulnerability in Internet Explorer.   

Scammers are always on the lookout for trending events to catch unsuspecting users in their trap. One such cunning attempt that redirected users to fake cryptocurrency giveaway sites was observed recently as Elon Musk struck deal with Twitter.
