On November 02, 2022, Skyward Finance experienced a vulnerability exploit and lost over 1.08 million $NEAR tokens worth approximately $3.2 million.
Skyward Finance is an on-chain asset issuance IDO platform that facilitates price discovery and equitable token distribution on the NEAR protocol.
The vulnerability was caused by a lack of check and parameter validation in one of the smart contract's functions.
In the exploit transaction , the hacker effectively withdrew wrap.near tokens multiple times within one transaction.
The exploiter purchased a large quantity of $SKYWARD tokens on Ref Finance before redeeming them on Skyward Finance via Treasury.
The vulnerability existed in the contract's redeem_skyward function, which is used to redeem the treasury from the protocol.
This function did not validate whether the passed in values of token_account_ids are duplicate entries.
The team informed that the Skyward Treasury was drained due to this attack, effectively rendering the Treasury and the $SKYWARD token worthless. They added that the contracts are fully locked, meaning that no one can pause or prevent future issues with the $SKYWARD token.
The lack of a recovery plan during hacks or exploits is typically indicative of an exit scam. A few of these activities leading to rug-pull in this industry are premeditated and self-made by the team in order to avoid prosecution or gain media attention before planning for their next venture.
This exploit could have been avoided if proper validation techniques had been used to ensure that no duplicate token_account_ids were passed during the functional call. It is also recommended that such values are not passed as parameters, because they can be easily manipulated.
