Over $765K worth of NFTs stolen after SIM swap attack on Gutter Cat Gang

The bad actors utilized a fake Gutter Cat Gang airdrop scam to drain people’s wallets, with at least $700,000 worth of NFTs being stolen from a single address.

More than $765,000 worth of nonfungible tokens has been stolen as part of a reported SIM swap attack on the Gutter Cat Gang NFT project.

The security breach was highlighted by several NFT community members at around 8 pm UTC on July 7, with Gutter Cat Gang co-founder @GutterMitch tweeting out a warning that: “Our Twitter has been compromised please do not interact with any links.”

Alongside the official Gutter Cat Gang account, co-founder @gutterric was also hacked.

The hacker, or hackers used the accounts to share links to fake “limited edition” Gutter Cat Gang NFT sneaker airdrops that essentially drained people’s hot wallets when they clicked on them.

In an effort to make the fictitious links look more legitimate, the tweets included recent Gutter Cat Gang branding and imagery from the project’s phygital sneaker drop in partnership with Puma and NBA/Charlotte Hornets star LaMelo Ball.

Responding to Gutter Mitch’s thread, prominent blockchain sleuth ZachXBT asserted that the team was hacked via a SIM swap attack, as he questioned the team’s cyber security practices.

“Your team better look at a compensation plan for victims as it is gross negligence to have used SMS 2FA on your socials after all of the recent SIM swaps,” ZachXBT said.

In a separate thread, ZachXBT highlighted two victims of the attack, with one losing a Bored Ape Yacht Club NFT worth $65,913 at current floor prices, and another losing a whopping $700,000 worth of NFTs from a host of blue chip collections.

At the time of writing, it appears that the accounts are still compromised.
