In the rapidly evolving world of cryptocurrency, security remains a paramount concern. Recently, a startling incident underscored this reality when a crypto trader lost a staggering $35 million in just a few minutes. This unfortunate event was brought to light by the blockchain security platform, Scam Sniffer, and serves as a stark reminder of the persistent threat posed by social-engineered crypto scams.
Unraveling the $35 Million Crypto Loss
The alarming loss involved 15,079 fwDETH, equivalent to $35 million, and was the result of a phishing attack that exploited a feature known as “Permit” signatures. Upon signing a phishing signature, the trader inadvertently authorized scammers to seize control of their funds. The attackers wasted no time in selling off the assets, leading to a precipitous drop in the value of dETH. This incident also had cascading effects, compromising protocols such as PAC Finance and Orbit Finance.
The “Permit” function, introduced through Ethereum Improvement Proposal (EIP) 2612, was designed to simplify transactions by allowing traders to approve transactions off-chain. This gasless transaction capability, however, comes with vulnerabilities. Unlike on-chain approvals, which provide visible warnings, “Permit” signatures lack such safeguards, making them a prime target for social-engineered scams.

Phishing Scams: A Persistent Threat in the Crypto Arena
Phishing scams have solidified their position as one of the most pervasive threats in the cryptocurrency landscape. Scam Sniffer has been pivotal in spotlighting these issues, recently drawing attention to the KOR Protocol’s compromised X account, which became a vector for phishing tweets. Such incidents underscore the effectiveness of social engineering in authorizing malicious applications and compromising user accounts.
The scale of this problem is highlighted in Scam Sniffer’s September Phishing Report. It was revealed that approximately 10,000 victims suffered losses nearing $46 million due to phishing scams. In the third quarter alone, phishing-related losses soared to $127 million, affecting an average of 11,000 individuals each month. Notably, two victims accounted for a significant portion of these losses, with one losing $32 million through a similar permit signature scam.
The total market capitalization of cryptocurrencies currently stands at $2.1 trillion, reflecting the immense value at stake. This emphasizes the need for vigilance and robust security measures to safeguard assets.
Common Vectors for Crypto Phishing Attacks
A critical examination of phishing vectors reveals that many attacks originate from deceptive platforms and advertisements. Scam Sniffer identified that a significant number of phishing incidents were triggered by users clicking on misleading links from fake accounts on platforms like X and via Google phishing ads. These ads often masquerade as legitimate resources, luring users into compromising their wallets.
One illustrative example provided by Scam Sniffer involved a Google phishing ad masquerading as a ‘Chainlist’ ad. Unsuspecting traders were enticed to connect their wallets, only to have their funds drained following the signing of a phishing signature.
As the crypto industry continues to grow, the sophistication of scams evolves in parallel. Traders and investors must remain informed and cautious, employing best practices in security to protect their digital assets. By understanding the methods and tactics employed by scammers, individuals can better guard against these pervasive threats.
