Scorpion says: “Recover from right here!” Be careful for emails from the crypto trade CoinPayments. Hackers are operating a brand new “Mortal Kombat” ransomware marketing campaign. The attackers disguise the phishing electronic mail attachment to appear to be cost transactions. Nevertheless, when opened, the payload routinely downloads both ransomware or a crypto-wallet skimmer. So it is a bit like a one-two uppercut. TOASTY!

Safety researchers from Cisco’s Talos cybersecurity crew have tracked a brand new ransomware marketing campaign that makes use of photos from Mortal Kombat in its ransom notes. The assaults began showing in December and indiscriminately goal people, small companies, and enormous firms.

As soon as contaminated, the affected laptop shows a Mortal Kombat 11 wallpaper connected to a notice instructing the sufferer to contact the attackers by way of an prompt messaging app referred to as qTox that anybody can download from GitHub. The attackers will then negotiate a worth to be paid in Bitcoin.

The assault vector is phishing emails made to appear to be they’re from the crypto buying and selling platform CoinPayments.
