Key Points:
- Layer 2 Connext has released an autopsy analysis of the airdrop claims issue.
- After DoS ends, claims return to normal. Over 20,000 users have requested 28,884,594 NEXT across 4 chains.
- Sybil attacked the Connext airdrop causing 274,956 tokens to be claimed and sold (0.26% of the tokens airdropped) for about 40k USDT.
Layer 2 Connext has released a post-mortem analysis of the airdrop claim issue on the X platform following yesterday’s Sybil airdrop attack.
Connext Network, a cross-chain interoperability protocol, is attracting attention after the community discovered a cryptocurrency wallet that appeared to have attacked Sybil to profit from the protocol’s airdrop.
Specifically, address 0x44Af had just received a large number of NEXT tokens through 230 different wallets, then quickly sold them into ETH, USDT, and USDC, raising nearly 39,000 USD. It is worth noting that this crypto wallet was created just 4 hours before the NEXT token distribution started.
After further investigation of on-chain data, the platform found that the majority of addresses did not appear to have transaction patterns indicative of Sybil’s activity. Instead, the wallets in question appear to have been compromised previously (not related to the platform).
But Connext is not compromised in any way. After the DOS attack ended, the airdrop application was back to normal. As of press time, over 20,000 users have requested 28,884,594 NEXT across 4 chains.
According to the report, although there was some concern in the community that this was an abuse of airdrop contracts, we were quick to rule out the possibility.
A Sybil attack in this case is a person or organization that creates hundreds or thousands of wallets and airdrops to make big profits. The purpose of this is to create a link between the wallets, thereby fooling the anti-Sybil system that all the wallets belong to an individual or organization. This will make it impossible for hacked wallets to receive the airdrop.
