StablR said a security vulnerability affected its EURR and USDR stablecoins and confirmed that an attacker profited about $2.8 million. The company stated on X that it is containing the issue and will disclose further details and follow-up measures after verification. This adds an official response to earlier reporting that linked the incident to weak Ethereum multisig protections, a reported private key compromise, depegging of roughly 20% or more, and conflicting estimates ranging from about $2.8 million in attacker profit to roughly $10.4 million swapped into 1,115 ETH after unauthorized minting of 8.35 million USDR and 4.5 million EURR.
