Statistics Of High-Profile SIM Swap Attacks Targeting Cryptocurrency Holders

SIM swap attacks have become a growing concern in the world of cryptocurrency, with numerous high-profile incidents shedding light on the severity of this threat. Understanding the real-life examples of these attacks can help crypto holders grasp the relevance and urgency of taking necessary precautions.

  • The incident of SIM swap attack targeting NFT collectors is the Gutter Cat Gang hack came to light on July 7, 2023, when Gutter Mitch, co-founder of the Gutter Cat Gang NFT collection, issued a warning, asking followers not to interact with any links posted on the project’s official X account since they had been compromised.The hackers used the compromised account to share phony links for limited edition Gutter Cat NFT sneaker airdrops, which resulted in the draining of users’ hot wallets upon clicking. The scammers reportedly made the fake links look authentic by incorporating recent Gutter Cat Gang branding and images from a sneaker collaboration with sportswear manufacturer Puma and NBA star LaMelo Ball. ZachXBT confirmed that in the attack, one Gutter Cat user lost a Bored Ape Yacht Club (BAYC) NFT valued at more than $65,000, while another lost several NFTs from various collections worth an eye-watering $700,000.
  • On Aug. 16, 2023, Blockchain Capital co-founder Bart Stephens lodged a legal complaint alleging a SIM swap hack that led to the theft of at least $6.3 million in various cryptocurrencies from his virtual wallets. In the lawsuit, Stephens asserted that the hacker, only identified as Jane Doe, exploited personal information found online and on the dark web to manipulate security procedures with his mobile service provider, allowing them to alter his account passwords. The hacker then secured Stephens’ mobile phone account, procured a new device, and transferred Blockchain Capital’s managing partner’s private number to a SIM on the new device. According to Stephens, his attackers then transferred millions of dollars worth of Bitcoin (BTC), Ethereum, Uniswap (UNI), Compound (COMP), and Maker (MKR) from his hot wallet. They also tried to steal another $14 million in ETH and BTC from Stephens’ cold wallet, but a vigilant Blockchain Capital employee thwarted the attempt. Stephens’ mobile service provider allegedly notified him of the SIM swap incident a day after the theft occurred. The hackers reportedly moved at least half of the stolen funds to a crypto tumbler, making tracing them more difficult.
  • The Sim-Swap attacks on Friend.tech’s users, as reported by CoinDesk and CoinTelegraph, brought the platform’s rapid rise to an abrupt halt. Sim-Swap attacks involve malicious actors gaining access to a user’s phone number and convincing the mobile carrier to transfer the number to a different SIM card under the attacker’s control. Once the attacker has control of the victim’s phone number, they can initiate unauthorized transactions and gain access to various online accounts linked to that number, including cryptocurrency wallets. Several Friend.tech users fell victim to these attacks, resulting in the unauthorized draining of their Ethereum holdings. The attacks served as a stark reminder that even the most promising blockchain projects are not immune to security vulnerabilities.
  • Bad actors took control of Vitalik Buterin’s X account on Sept. 9 to post a malicious link promising a free commemorative NFT from software giant Consensys. Users who fell for the ruse clicked the link and connected their wallets in anticipation of getting the Consensys NFT but instead had their accounts drained. Blockchain detective ZachXBT revealed that the scammers managed to siphon approximately $691,000 worth of crypto assets from hapless victims.
  • LayerZero CEO Bryan Pellegrino was another victim of a SIM swap attack. However, in his case, Pellegrino acted quickly enough to avert any losses from occurring due to the hack. According to him, the attacker probably retrieved his details from a badge he’d thrown in the trash upon leaving Collision 2023 in Toronto, Canada. Pellegrino first realized something was amiss when he checked his email and saw notifications from X informing him of changes to his account password. Upon learning it was a SIM swap, he used his company, LayerZero’s social media account, to warn users against engaging with any posts from his account. He also set about retrieving the account with the help of X staff, who also deleted all posts made by the hacker.
  • Well-known crypto enthusiast and NFT creator Cole (@ColeTherium) also lost his X account after a SIM swap attack on June 5, 2023. Cole’s Twitter account has been hacked. His phone number was compromised during the breach, leading to the hacker controlling all posts and direct messages (DMs) from his X account. Cole described the experience as a barrage of text messages leading to the disappearance of cell service and eventually a hostile takeover of his X account. The attacker impersonated Cole convincingly enough to persuade the NFT artist’s cell service provider, AT&T, to transfer his phone number to their device, allowing them to bypass 2FA security measures and access Cole’s X account. During the period of unauthorized access, the hacker initiated a scam involving a nonexistent IGLOO token, which they claimed was the official token for Cole’s former NFT project, Pudgy Penguins. ZachXBT linked the attack on Cole to a group he alleged had hacked more than eight social media accounts belonging to prominent crypto community members, stealing nearly $1 million worth of digital assets over several weeks.
