Unibot just announced on Telegram that yesterday's vulnerability has been completely resolved and has been restored to the old router. Unibot is completely safe and functional. It just takes a little more time to return these tokens and ETH to everyone. We are currently in the final rounds of running the simulation: several additional steps are being taken to ensure that the distribution is thorough and complete. For reference, there were over 100 different coins affected by the vulnerability, which is why it took a little longer than expected. The number of tokens of varying size and liquidity means there are more unique scenarios for refunds. As for refunds, they will be in the form of a mix of tokens and ETH.
According to previous news, Unibot was suspected of being attacked on October 31, resulting in a loss of nearly 200 ETH.
