Analyzing the Sybil Exploit in the Starknet Airdrop Attack, Resulting in a $5.4 Million Loss

Starknet experienced a major setback during its highly anticipated airdrop event on February 20th. What was supposed to be a joyous token distribution event turned into a scene of attack as a malicious actor exploited the system and carried out one of the most significant Sybil attacks in cryptocurrency history.

Unveiling the Sybil attack
The attacker cleverly manipulated the system during the airdrop by using multiple 1,361 wallets to claim the distributed tokens. According to data provided by the on-chain investigator, lookonchain, the attacker aggregated the tokens from these multiple wallets into a single address, managing to steal 1,432,800 STRK tokens, which were valued at approximately $3 million at the time of the attack.

All the stolen funds were transferred to a single wallet address, “0x027c…9078.” Surprisingly, just a few minutes ago, another airdrop participant received 1.22 million STRK tokens valued at $2.4 million through 1,800 wallets, bringing the total amount stolen in the attack to $5.4 million.

Impact on token price and market volatility
A Sybil attack is a type of cybersecurity attack that involves creating multiple accounts and pretending to be many people at once. The aftermath of these Sybil attacks affects the entire market, leading to significant volatility in Starknet’s token price. As of now, the token is valued at $1.89, experiencing a sharp decline of 57.2%.

Despite the project’s recent listing on Binance, which initially generated optimism and increased trading activity, the market sentiment quickly turned negative following the news of the airdrop’s key details. This trend is common in such airdrops and usually recovers after significant pumps.

Moving forward with the lessons learned
The importance of robust security protocols and risk management practices in the cryptocurrency space continues to grow. Airdrop events often reward community members and encourage active participation. However, they also attract malicious actors who seek to exploit vulnerabilities for personal gain. Illegitimate gains through unfair trading practices are unlawful, and crypto platforms should strengthen their security measures to prevent such pitiful attacks.
