According to EmberCN, during last year's Euler Finance hack, some stolen ETH was transferred into Tornado Cash. When the assets were returned, Euler Finance refused to accept the portion that had gone through Tornado Cash, considering it tainted.

According to @lookonchain, the Euler Finance exploiter, who stole $197M in March 2023 and later returned it, sent a 'Good job' message to the Penpiexyz exploiter. The Penpiexyz exploiter, however, did not return the $27.3M they stole and deposited the funds elsewhere.

According to PeckShieldAlert, the exploiter involved with Euler Finance has sent a message to the exploiter associated with Penpiexyz. This communication could signify a potential collaboration or information exchange between the two exploiters, which might impact the security and trading dynamics of both platforms.

According to EmberCN, the Penpie hacker transferred 5,600 ETH ($13.44 million) through Tornado Cash five hours ago, ignoring the Penpie project's request to return the assets. Additionally, the hacker who stole $197 million from Euler Finance in March last year praised the Penpie hacker in an on-chain message.
