MultiversX mainnet suddenly paused. The official said someone tried to exploit an atomicity vulnerability in the virtual machine layer, causing abnormal changes to on-chain state. The team has already tested a fix in a shadow fork environment, but the estimated time to resume hasn’t been announced yet.

Almost at the same time, an Ethereum contract associated with $FET was also attacked, with losses of about $2 million. The attacker obtained a legitimate conversion signature from TokenConversionManagerV3 and drained the remaining tokens directly. Blockaid said the attack is still ongoing.

One Layer1 has been forced to go offline to protect itself, while an AI concept coin’s contract was precisely breached. Both involve non-BTC/ETH smaller-cap coins. During this cycle, security incidents have been more damaging than market volatility, yet many holders of $EGLD still haven’t realized that trading on the mainnet is no longer possible. What’s even more worth pondering is that the methods behind both attacks are not simple—whether they are connected is still unclear.
