New MassJacker malware targets piracy users, steals crypto
CyberArk found nearly 780,000 wallets linked to the theft, though only 423 held any crypto at the time of the analysis.
A previously unknown type of cryptojacking malware called MassJacker is targeting piracy users and hijacking crypto transactions by replacing stored addresses, according to a March 10 report from CyberArk.
The cryptojacking malware originates from the website pesktop[dot]com, where users seeking to download pirated software may unknowingly infect their devices with the MassJacker malware. After the malware is installed, the infection swaps out crypto addresses stored on the clipboard application for addresses controlled by the attacker.
According to CyberArk, there are 778,531 unique wallets linked to the theft. However, only 423 wallets held crypto assets at any point. The total amount of crypto that had either been stored or transferred out of the wallets amounted to $336,700 as of August. However, the company noted that the true extent of the theft could be higher or lower.
