Ethereum Whale Hacked for $27 Million Due to Private Key: Which Tokens Were Lost?

Ethereum Whale Hacked for $27 Million Due to Private Key: Which Tokens Were Lost?

According to PeckShield, an Ethereum whale’s multisig was drained for about $27.3 million after a private key compromise, and the attacker has already funneled about $12.6 million, around 4,100 ETH, through Tornado Cash, while keeping about $2 million in liquid assets on hand.

Etherscan-linked traces shown in the screenshots point to address "0x1fCf1" repeatedly sending out 100 ETH chunks to Tornado Cash, the kind of pattern that looks less like one "panic move" and more like a planned laundering schedule, and the same set of screens also ties the drainer to control over the victim’s multisig.

#PeckShield A whale's Multisig was drained of ~$27.3M due to a private key compromise.

The drainer has laundered $12.6M (4,100 $ETH) via #TornadoCash and retains ~$2M in liquid assets.

The drainer also controls the victim's multisig, which maintains a leveraged long…

That control matters because, per the Aave interface capture, the victim's multisig still sits on a leveraged ETH long: about $25 million in Ethereum supplied against about $12.3M DAI borrowed, with a health factor displayed around 1.68, meaning the wallet is alive, but not "sleep easy" alive, if ETH slides.

So, which tokens were involved? 

The Etherscan wallet overview in the images shows 100.3184 ETH worth about $284,640 plus holdings around $1.37 million across 201 tokens, with the most visible major lines being 303.44 WETH, equal to around $860,973; 2,216.36 OKB for another $234,802); 4,928.74 LEO at $36,374) and 151,990.97 FET, which made $30,870 more.

The near-term risk is not just what was taken but what gets forced: if ETH drops hard enough to pressure that Aave health factor, liquidations can turn collateral into automatic selling, and the attacker does not need to "dump everything" to create this ugly selling wave.

The Biggest Winner in the AI Fundraising Frenzy: Goldman Sachs Remains the King of Wall Street

In a single day, three AI mega financing deals totaling over $210 billion took place, and Goldman Sachs’ name appeared in each one: co-leading Meta’s $95 billion stock offering, exclusively overseeing the $40 billion chip financing structure for SpaceX, and serving as the lead bookrunner for Anthropic’s IPO. The AI financing supercycle is reshaping the competitive landscape on Wall Street, with Goldman Sachs taking the lead in turning relationship advantages into real money.

Anthropic may secure the "largest IPO in the stock market," but may not achieve "investment grade in the bond market"

The prospectus reveals that the company is already burdened with $6.2 billion in current liabilities, and its uninitiated lease commitments have soared from $50 billion to $321 billion, with an additional $77 billion in hidden borrowing options. The off-balance-sheet "chip financing" structure it has built in partnership with Broadcom is considered a potential counterparty risk due to circular trading. In comparison, SpaceX made a clear commitment to an investment-grade credit rating and successfully completed a $25 billion bond issuance. Anthropic, however, has barely mentioned an investment-grade credit rating, making it difficult for bond market buyers to price its offerings.
