Web3 is Going Just Great

The attacker was successfully able to transfer around 13.8 million STX (~$2 million) on the Stack BTC layer-2 chain. However, their attempts to steal assets notionally worth around $4.3 million from the project's BNB Chain implementation failed when they upgraded the project contract to a malicious version, but failed to prevent other people from calling the withdraw function. The attacker's first transactions to withdraw the funds themself failed, and an apparent whitehat hacker was able to step in and complete the withdrawal ahead of the exploiter. They later negotiated a deal for the funds' return, after offering a 10% "bounty".

The exploiter had also tried, and failed, to steal assets notionally worth around $5 million on the Ethereum blockchain, but failed to do so. ALEX Lab later announced they were able to recover or secure around $4.5 million of those assets. ALEX also later announced that they believed the attackers were part of the North Korean Lazarus Group.

After being alerted to the theft by several security companies, Sonne announced they had paused the contract on the Optimism Ethereum layer-2 chain.

In the past, Robinhood has removed cryptocurrencies from trading after they were alleged to be securities by the SEC, such as Solana (SOL), Cardano (ADA), and Polygon (MATIC) in the wake of the lawsuits against Binance and Coinbase. However, given the SEC's stance that most cryptocurrencies are securities, it seems likely that the SEC believes one or more of the 14 non-bitcoin cryptocurrencies Robinhood offers may also be a security.

Robinhood's Chief Legal Officer issued a statement that "We firmly believe that the assets listed on our platform are not securities and we look forward to engaging with the SEC to make clear just how weak any case against Robinhood Crypto would be."

Cred had claimed to customers that they engaged in only "collateralized or guaranteed lending", hedged their investments, and "comprehensive insurance", but hid that "virtually all the assets to pay the yield were generated by a single company whose business was to make unsecured micro-loans to Chinese gamers." Furthermore, they did engage in uncollateralized lending, did not hedge their investments, and did not hold insurance as they had claimed.

Around $150 million in customer funds were lost in the collapse based on prices at the time, though those crypto assets would have been priced substantially higher at various times since.

The first attack, on April 26, was enabled by a flaw in the security measures related to transfers of the USDC stablecoin. An attacker was able to change the recipient address and amount, ultimately making off with almost $300,000 in the stablecoin. Pike released a postmortem two days later, acknowledging that the bug had been identified by a third-party auditor but had not been rectified by their team.

When the Pike team went to patch the smart contracts to thwart this attack, they introduced new, even worse vulnerabilities. As a result, on April 30, an attacker was able to upgrade the project's smart contracts to malicious ones, then withdraw $1.68 million in ETH, ARB, and OP tokens.

Pike Finance has offered a 20% reward for the return of the funds or information pertaining to the attacker, and has promised "a plan to make users whole". Pike, which launched in early 2024, is backed by Circle and Wormhole.
