Shocking Sybil Attack Uncovered: Individual Controls Over 21,000 Wallets on zkSync Network According to a recent X thread,
it has recently come to light that an individual has orchestrated an incredibly sophisticated Sybil attack on zkSync, a layer-2 scaling solution for Ethereum.
This Sybil attack has given this individual control over a staggering 21,877 wallets within the network.
The individual's strategy involved
a meticulously designed bot, which they utilized to execute
various transactions within the zkSync network. Notably, these transactions
were not manually conducted but automated by the bot. This level of automation allowed
for a high degree of precision in the attack.
One key aspect of this attack was the individual's ability
to manipulate liquidity within the network. By adding liquidity themselves,
this actor was able to evade issues related to slippage that might have otherwise occurred. Consequently, they could execute a series of transactions
on the zkSync Era network with remarkable efficiency and
cost-effectiveness.
Furthermore, the individual behind this attack
demonstrated a keen understanding of how to minimize costs. Despite accumulating an impressive
volume of transactions across the 21,877 wallets, they managed to do so with minimal fees.
