Less than 48 hours after Polygon's Discord was hacked, the official Discord servers of the L1 network Avalanche and the L2 chain ZKsync were also attacked. The Avalanche team has "discovered" the issue and fixed it, and is working to get the server back to normal. Only an hour after the Avalanche vulnerability was exploited, the official ZkSync Discord was also hacked. The hacker once again shared the malicious link of the fake "second round airdrop" scheme, promising free ZK tokens to users. Some ZkSync team members have noticed the vulnerability. (Cointelegraph) Previously, Polygon Chief Information Security Officer Mudit Gupta said on the X platform that he has regained access to the Polygon community Discord and is cleaning up all changes made by the hackers to ensure that the intrusion cannot be repeated.
