The digital revolution and rise of cryptocurrencies have created unprecedented opportunities for innovation, economic growth, and social improvement. However, they have also opened a Pandora's box of cyber threats, with scammers deploying increasingly sophisticated tactics to prey on the unwary. A classic example is a previously undetected cryptocurrency scam that has been using over 1,000 fraudulent websites to lure users into a bogus rewards scheme since early 2021.
The Deceptive Cryptocurrency Scam
Reported by Trend Micro, this sophisticated scam is linked to a Russian-speaking threat actor named "Impulse Team." Users are led to believe they've won a substantial amount of cryptocurrency. However, to access their 'reward,' they need to pay a small activation fee. In essence, this is a classic case of an advanced fee fraud, redesigned for the digital age.
The scam starts with a direct message via Twitter, urging recipients to sign up for an account on a decoy website and apply a promo code to win a reward. However, once an account is created on the fraudulent platform, users are requested to make a deposit to confirm their identity. This scam has yielded the actors over $5 million between late 2022 and early 2023.
Building a Web of Deception
The fraudsters have meticulously built hundreds of domains related to this fraud, some dating as far back as 2016. The fraudulent sites belong to an affiliate "scam crypto project" called Impulse, advertised on Russian cybercrime forums since February 2021.
Similar to ransomware-as-a-service (RaaS) operations, the scam requires affiliate actors to pay a fee to join the program and share a percentage of earnings with the original authors. To give this operation an air of legitimacy, the scammers created a lookalike version of a known anti-scam tool known as ScamDoc, which assigns trust scores to different websites.
Key Terms
Advanced Fee Fraud: This type of fraud convinces victims to pay a fee upfront on the promise of receiving a larger amount of money or reward later, which never materializes.
Ransomware-as-a-Service (RaaS): A cybercrime model where the original ransomware creators sell or lease ransomware to other criminals, often for a percentage of the eventual profits.
ScamDoc: An online tool that estimates the trustworthiness of websites based on several factors, including domain age, owner identity, and security certificates.
Computer Security Operations Center (CSOC): A central unit that oversees cybersecurity incidents, equipped with a team of security analysts who actively monitor and defend against cyber threats.
In Summary
Cryptocurrency scams, such as the one perpetrated by the "Impulse Team," exploit the growing interest in digital currencies and demonstrate the importance of vigilant cybersecurity measures. CSOCs play a pivotal role in defending against these and other cyber threats by detecting, analyzing, and responding to incidents in real time. Awareness training for users, robust incident response strategies, and advanced threat intelligence tools form the cornerstone of a comprehensive cybersecurity strategy.
The internet, and in particular the world of cryptocurrencies, offer immense potential for growth and innovation, but they also come with risks. With scams becoming more sophisticated, it is more important than ever to stay informed and take preventative measures to protect ourselves in the digital world.
