A mismatch within the reported cost of underlying assets on synthetic assets DeFi platform Mirror Protocol is responsible for a continuing exploit that can drain all its funds.
The exploit was observed on May 29 by governance participant ‘Mirroruser’ around the protocol’s forum. As of times of writing, the mBTC, mDOT, mETH, and mGLXY synthetic asset pools around the protocol have forfeit the majority of their assets worth over $two million.
A prices error for Luna Classic (LUNC) made the exploit possible. The rest of the validators on Terra Classic reported the cost of LUNC ($.000122) was identical to the recently launched LUNA ($9.32) despite the fact that their real market prices vary extremely based on CoinGecko.
Chainlink community ambassador ‘ChainLinkGod’ described on May 31 the “Terra Classic validators were running an outdated form of the oracle software.”
.@mirror_protocol just been exploited again because of Terra Classic validators reporting the cost from the new Terra 2. $LUNA gold coin (~$9.80) rather from the original Terra Classic $LUNC gold coin (~$.0001)

Venus Protocol and Blizz Finance each endured from the similar exploit in May when cost oracle Chainlink’s reported LUNA cost continued to be at $.10 as the market cost ran far below that. Blizz Finance was entirely drained while Venus lost $11.two million.
Terra community whistleblower on Twitter, pseudonymous ‘FatMan’, cautioned the Mirror exploit will modify the other ‘m’ asset pools by 8:00am UTC on May 31. However, the account also claims that the majority of the pools could be saved when the developers intervene to repair the bug.
By 12:55am UTC, it made an appearance the prices error have been fixed for LUNC, because the cost being verified through the oracle has came back to the real market price.
This is actually the second time Mirror has endured from the major vulnerability. The prior bug in Mirror’s code was exploited “hundreds of times” since 2021 based on FatMan inside a May 27 tweet. The very first exploit permitted a person to unlock other users’ collateral around the protocol and pull it themselves. In most, the very first exploiter got away with “well over $30 million” and it was not observed until May 2022, he added.
On May 28, the Terra ecosystem was relaunched when Terra 2. went online according to founder Do Kwon’s plans. Terra 2. is really a fork from the now-named Terra Classic blockchain. LUNA tokens are now being airdropped to investors who held the prior form of LUNA and also the TerraUSD (UST) stablecoin throughout the catastrophic collapse from the Terra ecosystem earlier this year.
Mirror Protocol (MIR) tokens are presently lower 2% previously 24 hrs and therefore are buying and selling at $.31 based on CoinGecko.
