The bot that became infamous for targeting decentralized finance (DeFi) protocols under the name of Jaredfromsubway.eth is back with totally new and more evolved techniques.
A Missing and Reappearance of the Bot, Jared
Until recently, Jared’s bot was very active, trading with the help of contract address 0x6b75...9a80. However, no trading activity was noticed after August 7 and completely ceased by August 14. This resulted in concerns about the possibility of the bot's shutdown. From August 1 to 14, the bot paid out 851 Ether (approximately $2.2 million) in grants to people who enable these trades.
The New and Enhanced Bot
Jared didn’t leave for long. An improved bot associated with the same account as the prior one has appeared with further techniques. Unlike the previous bot, this new bot has been relatively very active; it performed around forty thousand transactions in two weeks under a new contract address. Such trades have produced 765 ETH in rewards, and as expected, Beaverbuild and Titan are among the biggest beneficiaries.
What is New in these attacks?
The new bot has more elaborate courses of action in its aggressive tactics. While traditional sandwich attacks use high and low prices to place trades before and after the transaction, the new bot includes additional actions like adding and removing liquidity from Uniswap pools on the same block with the targeted transaction. This makes the bot's activity difficult to discover and stop. However, as the bot becomes more intelligent and selective, it constantly searches for new ways to take advantage of these protocols and therefore remains a threat.
The return of the bot Jaredfromsubway.eth with new methods poses significant challenges for the DeFi community in terms of detection and prevention. Despite efforts to create stable protocols, attacks are becoming more sophisticated, requiring new protective measures.
