StablR stablecoin was compromised after an attack, and the attackers have profited approximately $2.8 million.

According to Mars Finance, stablecoin issuer StablR suffered a sustained attack, causing its Euro stablecoin EURR to de-peg to its US dollar stablecoin USDR. Blockchain security company Blockaid stated that the attackers allegedly gained control of the private key of one owner in the minting multi-signature account, replacing other administrators under a mechanism requiring only 1/3 signatures, and minting an additional 8.35 million USDR and 4.5 million EURR. Subsequently, the attackers exchanged approximately $10.4 million worth of tokens for approximately 1,115 ETH on a DEX, actually profiting approximately $2.8 million. Affected by the incident, EURR briefly fell to around $0.88, and USDR fell to around $0.7. Blockaid pointed out that this incident was not due to a smart contract vulnerability, but rather a failure of the key management and governance mechanisms.
