Cryptocurrency has become a popular form of digital currency, allowing users to engage in secure and decentralized transactions. However, with its increasing popularity comes an increased risk of cyber attacks and theft. Experts have recently warned of a new threat that allows hackers to steal people’s cryptocurrency wallet seed phrases, even when they are stored as an image file.
When a user sets up a new crypto wallet, they receive a seed phrase, which is a set of 12 or 24 random words. This seed phrase serves as the key to restore the wallet in a new app or device in case of loss or theft. It is crucial to keep this seed phrase secure and private to prevent unauthorized access to the wallet.
Typically, users are advised to write down their seed phrase and store it in a secure location. However, some users opt to save the seed phrase as an image file, such as a screenshot, for convenience. This practice may seem harmless, but it can make the job of the criminals that much easier.
A recent threat known as Rhadamanthys version 0.7.0 has emerged, equipped with new and advanced capabilities. Recorded Future’s Insikt Group conducted an analysis of this new version and found that it includes Artificial Intelligence (AI) capabilities and optical character recognition (OCR). These tools combined are referred to as “Seed Phrase Image Recognition,” enabling the malware to extract seed phrases from image files.
“This allows Rhadamanthys to extract cryptocurrency wallet seed phrases from images, making it a highly potent threat for anyone dealing in cryptocurrencies,” stated Recorded Future’s Insikt Group in its analysis. “The malware can recognize seed phrase images on the client side and send them back to the command-and-control (C2) server for further exploitation.”
Rhadamanthys, even before the introduction of these new features, was already a formidable infostealer. It was first discovered back in 2022 and has since become one of the most popular and powerful pieces of malware. Hackers can subscribe to the service, paying a monthly fee of $250 or $550 for 90 days.
The latest version of Rhadamanthys, released in June 2024, is considered a complete rewrite of both client-side and server-side frameworks, improving the program’s execution stability. This suggests that the developers of this malware are continuously updating and refining it to enhance its effectiveness and evade detection.
The implications of this new threat are significant for individuals and businesses alike. Cryptocurrency wallets can store substantial amounts of digital currency, and the loss of a seed phrase can result in devastating financial consequences. Therefore, it is crucial for users to understand the risks involved and take appropriate measures to protect their seed phrases.
First and foremost, users should avoid saving their seed phrases as image files, as this makes them vulnerable to attacks like Rhadamanthys. Instead, it is recommended to follow best practices and write down the seed phrase on a piece of paper or store it securely using offline methods.
Additionally, it is important to stay updated on the latest cybersecurity news and threats. By staying informed, users can take proactive measures to protect their cryptocurrency assets. They can implement strong security measures, such as using reputable antivirus software, enabling two-factor authentication, and regularly updating their software and wallets.
Furthermore, users should exercise caution when interacting with unknown or suspicious sources. Phishing attacks, where hackers try to trick users into revealing their seed phrases or login credentials, are common in the cryptocurrency space. Users should be vigilant and verify the authenticity of any requests or messages they receive regarding their cryptocurrency wallet.
In conclusion, the emergence of Rhadamanthys version 0.7.0 highlights the evolving and sophisticated nature of cyber threats targeting cryptocurrency users. The ability of this malware to extract seed phrases from image files is a concerning development that puts users at significant risk. It is essential for individuals and businesses to take proactive measures to secure their cryptocurrency wallets and remain vigilant in the face of emerging cyber threats. By following best practices and staying informed, users can minimize the risk of falling victim to these malicious activities.
