X100 Exploit Continues: Third Attack Drains Half Million Tokens from Uniswap

A third major exploitation of the X100 token drained over 549,000 tokens from a Uniswap liquidity pool, marking an ongoing pattern. The recurring attacks suggest systemic vulnerabilities in the token contract itself rather than issues with the underlying AMM infrastructure.

The X100 vulnerability has claimed another victim. A fresh transaction routed approximately 549,916 X tokens along with 1,909 USDT to a new address, marking the third documented instance of this recurring exploit. What makes this latest attack particularly revealing is the disparity between the value extracted and the liquidity theoretically available—the targeted pool contained less than 200 USDT in reserves at the time of the transaction. This suggests attackers are exploiting a fundamental disconnect between actual pool reserves and the contract's recorded state, a pattern consistent with reentrancy vulnerabilities or improper balance tracking mechanisms.

The repeated nature of these attacks indicates a systemic flaw rather than an isolated incident. X100, despite its trading activity on Uniswap, appears to contain a recurring vulnerability that skilled actors can reliably weaponize. Each successive drain represents a significant capital loss, though the shift between beneficiary addresses suggests either sophisticated money laundering infrastructure or multiple independent threat actors discovering and exploiting the same weakness. The fact that these transactions continue to execute successfully against Uniswap pools—one of the most audited and mature automated market makers in DeFi—underscores how vulnerabilities often persist not at the infrastructure layer but within individual token contracts themselves.

This scenario reflects a broader challenge in crypto markets: the responsibility for contract security falls squarely on token developers, yet many lack the resources or expertise to conduct rigorous security audits before launch. Uniswap itself functions precisely as designed, faithfully executing trades based on submitted parameters. The vulnerability exists upstream, in how X100 handles token transfers, balance updates, or state management during interactions with external protocols. Liquidity providers who've supplied capital to affected X100 pairs face direct losses, compounded by the reputational damage that successive exploits inflict on the token itself.

As these attacks continue, the crypto community faces renewed pressure to develop better mechanisms for identifying vulnerable token contracts before significant liquidity pools form around them. Whether through improved static analysis tools, mandatory disclosure requirements, or post-deployment monitoring systems, the ecosystem must find ways to surface these patterns faster—or see increasingly sophisticated attackers repeatedly extract value from the same architectural flaws.
