Coinbase, along with employees of the Federal Communications Commission (FCC) and other leading cryptocurrency firms such as Binance, Gemini, Kraken, ShakePay, and Trezor, has become the primary target of a sophisticated phishing campaign. This campaign, employing a newly uncovered toolkit known as CryptoChameleon, presents a considerable threat to both individuals and organizations alike.
Cybersecurity analysts at Lookout have uncovered the intricacies of the attack, revealing that the perpetrators are creating convincing single sign-on pages for Okta, a widely-used cloud service provider for authentication. These fraudulent pages closely mimic authentic ones, making it difficult for unsuspecting victims to discern the scam.
“This phishing kit first asks the victim to complete a captcha using hCaptcha. This is a novel tactic that prevents automated analysis tools from crawling and identifying the phishing site.”

The attack employs a multi-stage social engineering approach, utilizing emails, SMS, and voice phishing techniques to deceive targets into divulging sensitive information such as usernames, passwords, password reset URLs, and even photo IDs. Primarily targeting individuals in the United States, the campaign has successfully compromised over 100 victims, with ongoing phishing activities detected.
Coinbase And Real-Time Phishing Interaction
One of the notable features of the phishing kit is its ability to engage in real-time interaction with victims, allowing for dynamic customization of pages to include specific details such as phone number digits, thereby enhancing the illusion of legitimacy. Analysis conducted by Lookout has identified the majority of phishing activities being hosted on servers by Hostwinds, Hostinger, and a Russia-based entity known as RetnNet.
At present, neither Coinbase, Binance, Kraken, nor Gemini has issued public statements addressing the situation. Moreover, it remains uncertain whether the hackers have managed to gain unauthorized access to private data.
This incident underscores the persistent threat posed by cybercriminals, particularly in the realm of cryptocurrency. In January, blockchain security firm SlowMist revealed that over 80% of comments on publications of prominent projects on X were linked to phishing activities. Scammers have been actively targeting cryptocurrency projects on platforms like Telegram, exploiting vulnerabilities to perpetrate fraudulent schemes.
Given the evolving sophistication of cyberattacks, it is crucial for both individuals and organizations, including Coinbase, to maintain constant vigilance and implement robust security measures to defend against such threats. Increased awareness, alongside proactive security protocols, plays a pivotal role in minimizing the dangers presented by malicious actors in the digital realm.
