“We identified the issue and resolved it. In the process, we had to remove suspicious channels and roles […]. We will work diligently to restore everything to normal. Thank you for your patience,” wrote community head Ben Well.
Just an hour after the attack on Avalanche, users reported a breach of the official ZKsync Discord channel.

The incidents involving Avalanche and ZKsync channels occurred a day after the Discord server of the Polygon blockchain platform was compromised.
Chief Information Security Officer Mudit Gupta urged users not to click on the posted links “until further notice.”
PSA: Do not click on any links in the @0xPolygon community discord until further notice.
It has been compromised and we’re trying to get back ownership.

“The channel is compromised, and we are trying to regain ownership,” he clarified.
One user reported losing $150,000 in Ethereum “through an official Polygon announcement in Discord.”
@0xPolygon I lost $150,000 of my Ethereum pool in one go through Polygon’s official Discord announcement. Why haven’t you officially posted the Discord hacking issue on X? How are you going to take responsibility for this?

“Why haven’t you officially reported the hack on X? How are you going to take responsibility for this?” he asked the team.
In 2023, experts uncovered a phishing scheme involving the distribution of messages with malicious links via Discord.
