Crypto Individual Manipulates 21,877 zkSync Wallets In Complex Sybil Attack

September 11, 2023 - Around 2 mins mins to read

Key Points:

  • One person controls 21,877 zkSync wallets.
  • The attacker whitelisted wallets, created a private token, and deployed a private DEX.
  • Matter Labs is actively addressing the situation, highlighting the need for vigilance in crypto.
In a shocking revelation, it has come to light that a single individual has orchestrated an elaborate Sybil attack on zkSync, controlling a staggering 21,877 wallets within the network. This alarming discovery exposes the intricacies of the individual’s tactics.
Crypto Individual Manipulates 21,877 zkSync Wallets In Complex Sybil Attack

The perpetrator initiated their scheme by funding each wallet with small amounts of Ether and subsequently deploying a proprietary token named Gemstone (GEM), which was not open source. They then proceeded to whitelist all their wallets, claiming all self-deployed tokens in the process.

To facilitate transactions between these wallets, the individual even went as far as creating a non-open source decentralized exchange (DEX), allowing indirect transfers of assets.

To boost the value of GEM tokens, the attacker added liquidity with over 80 ETH to their own DEX contract. This strategic move was followed by testing the market by trading GEM tokens. Subsequently, they swapped GEM tokens claimed from the 21,877 wallets for a profit ranging from 0.6 to 0.7 Ether.

All of these transactions were automated, and executed by a bot meticulously programmed by the attacker. This approach allowed them to maintain control and avoid manual intervention.

Remarkably, the attacker adjusted liquidity as needed, achieving a $10,000 volume and 10 transactions per wallet while only incurring fees ranging from $1.5 to $2 in Ether. They carefully timed transactions across different months, weeks, and days to resemble other Layer-2 projects’ activities.

While the extent of the attacker’s reach was limited to 10,000 wallets due to zkScan Explorer’s history constraints, Matter Labs, the team behind zkSync, is actively working to identify and mitigate the Sybil attack through GEM token claim contract detection.
