Quick Sync Exploited in Targeted Attack, Token Falls By 99% In 7 Days

Quick Sync has suffered a major exploit, resulting in the loss of a significant amount of its native $QS token. The price for $QS has fallen by over 99% in the past 7 days.

The team disclosed the incident in a statement, attributing the attack to a targeted social engineering scheme involving compromised wallets.

What is weird to see is that the X post by the team saw only positive comments from KOLs and community members which is very difficult to see once the price falls so much (even with recovery plans).

Wallets Drained After Browser-Based Breach

According to Quick Sync, the attack began with a meeting request from a VC posing as a legitimate investor. The attackers requested communication via WeChat and shared a malicious meeting link. That link allegedly delivered a script that harvested browser data and wallet session information.

When the team later accessed their wallets—used for salaries and token claims—via browser, the attackers were able to drain funds. Both the deployer and tax wallets were compromised, as well as a revenue wallet.

Quick Sync confirmed that the hackers gained full control of the deployer wallet. All remaining unlocked QS tokens were claimed and sold across multiple wallets.

Liquidity Pulled to Preserve Treasury

In response, the team immediately emptied the project’s liquidity pool to prevent additional losses. Remaining treasury assets are now earmarked for recovery and relaunch efforts.

The affected hacker wallet addresses have been disclosed:

• 0x1a8a36382086738d33fd561de8bfad4ad59eded1
• 0x04824e8389f22cb073625b2ad7009ba344277fab

Operations Unaffected, Token Relaunch Planned

Quick Sync emphasized that the incident was limited to wallet security and token control. Its main applications—QS Share and StageX—remain fully operational and unaffected.

The team is preparing to relaunch the $QS token and has announced a 1:1 airdrop for existing holders. Users are instructed to send their current QS tokens to the following address to receive the new token:

• 0x138d034F8f78BaB2a43b1C691Ea3371DAF99CD16

A snapshot and recovery plan for stakers is currently in development, with more information to follow.

Quick Sync acknowledged operational missteps and has pledged to overhaul internal security. Future operations will rely on hardware wallets, multi-signature protection, and improved operational security protocols.

Despite the breach, the team reiterated its commitment to continuing development. “We’re not starting over, we’re stepping forward,” the statement reads.

A detailed relaunch announcement is expected soon.
