Forensic narrative

Tender.fi is suspected of being attacked by white hat hackers and lost $1.59 million. Hackers used Tender.fi’s misconfigured oracles to borrow $1.59 million worth of crypto assets with just $70 worth of GMX tokens as collateral. On March 8, on-chain data showed that the hackers who attacked the Arbitrum ecological lending protocol Tender.fi had returned their funds, and the Tender.fi team agreed to pay the hackers 62 ETH ($96,500) as a bounty. Attack method (per SlowMist): Oracle Attack. Reported loss: $ 1,590,000.
