A hacker, who on Monday stole $8.3 million from the personal pockets of Nexus Mutual CEO Hugh Karp, has despatched a ransom demand for $2.66 million in Ether (ETH) embedded within the enter information of an Ethereum transaction.

Within the poorly-worded Dec. 16 message, the attacker addresses Karp immediately, and appears to counsel that they are going to stop promoting off the stolen NXM till the worth recovers or Karp sends 4,500 ETH.

“Howdy Hugh. I cannot promote wNXM any extra till wNXM recovers his worth otherwise you ship me 4.5k ETH. Should you want any negotiation with me, ship msg to my eth tackle. Following are your addresses. You’re wealthy, Hugh […]”

It’s unclear if the hacker supplied to return the rest of the stolen NXM within the latter state of affairs, although this could doubtless be a prerequisite situation for Karp if he decides to ship the ransom.

Any negotiation is requested to be directed through the attacker’s Ethereum tackle, and the message concludes by itemizing three pockets addresses claimed to belong to Karp, together with the assertion that he’s “wealthy.”

As Cointelegraph reported, the hacker supposedly managed to put in a compromised model of Metamask that tricked Karp into signing a transaction transferring all his 370,000 NXM to the attacker’s pockets.

In a tweet, Karp complemented the attacker on some “subsequent degree stuff,” whereas noting that it will be troublesome to money out a lot NXM, and providing a $300,000 bounty if the tokens have been returned in full.

Nevertheless, undeterred, the attacker has reportedly already laundered as much as $2.7 million price of the stolen NXM, and is now demanding an identical quantity to not dump the remaining.
