Earlier, the protocol disclosed it was the victim of a token approval exploit when moving to a new router, and it would reimburse any stolen funds.
We experienced a token approval exploit from our new router and have paused our router to contain the issue.

Any funds lost due to the bug on our new router will be compensated. Your keys and wallets are safe.
We will release a detailed response after investigations conclude.
Tornado Cash is often at the nexus of high-profile hacks and exploits in the crypto world. In August, some of its development team were charged with helping hackers launder over $1 billion, including from entities tied to North Korea. Volume on the privacy protocol is down 90% after the arrests and subsequent sanctions.
The price of the Unibot token is down nearly 25% to just over $42. The price of the token peaked in mid-August at almost $220. The protocol, at its peak, generated a significant amount of revenue, thus attracting the interest of investors.
This is the latest exploit in the crypto world. Last week, LastPass users lost $4.4 million worth of crypto.
According to data spotted by Lookonchain, the attacker’s wallet now has just over $630,000 in crypto assets, with the majority being in ether (ETH) followed by USDC.
UPDATE (Oct. 31, 08:20 UTC): Adds details from Peckshield, updates headline.
