- The hacker is a self-described Argentine and a "Peronist," according to cryptic messages after the return of $200 million in stolen crypto.
- In March, the hacker took advantage of a vulnerability in Euler code to steal roughly $200 million worth of crypto from the lending protocol.
Two months after returning $200 million in stolen crypto, the Euler hacker on Saturday sent a pair of cryptic messages — the self-proclaimed Argentine and a “Peronist” urged beginner hackers to pursue bounties rather than stolen riches.
The messages were encoded in transactions the hacker made Saturday evening London time. The first message read “Bùen Áyre,” meaning Buenos Aires. The hacker dedicated the second “to those beautiful people … who are all Argentines.”

“If there is an Argentine hacker, and a Peronist, it’s me, no one else!,” the message, written in Spanish, reads. “For hackers who are just starting out: don’t be stupid, don’t steal, do bounties, etc.”
In March, the hacker took advantage of a vulnerability in Euler code to steal roughly $200 million worth of crypto from the lending protocol. Due to Euler’s widespread integration with other DeFi protocols, the hack had a cascading effect on the ecosystem, causing losses for users of other protocols and causing one stablecoin to lose its peg.

After three weeks of negotiations, however, Euler recovered all of the “recoverable funds.” Because the hacker converted most of the stolen crypto to Ether, and because the price of Ether rose during the negotiations, Euler effectively recovered all of the stolen crypto and then some.
At the time, the hacker self-identified as a person named “Jacob,” and apologised for the exploit.
“I don’t think what I say will help me in any way but I still want to say it. I fucked up,” the hacker wrote at the time. “The rest of the money will be returned ASAP. I only look after my safety, and that is the reason for the delay.”

The hacker’s ties to Argentina are unclear. DL News previously reported the hacker had sent 100 Ether — worth over $130,000 at the time — to an Argentine Solidity developer shortly after the hack.
The developer had pleaded with the hacker to return the 78 wrapped, staked Ether he had lost. The hacker returned the crypto and then some. When contacted by DL News, the developer promised to return the excess crypto, and denied he was involved in the hack.
The hacker’s most recent message included a cryptic warning: “Choose well in October, we are going with everything.”
It also included a shout out to a seemingly nonexistent social media handle, @federicojaimeok.
Euler declined to comment on the hacker’s latest message.
