Android Malware Can Steal Private Keys From Screenshots and Images

As an analyst with over two decades of experience in cybersecurity, I’ve seen my fair share of threats targeting digital assets and personal information. The latest scheme using SpyAgent malware to steal crypto credentials is yet another reminder that no one is immune to these attacks, whether you’re in South Korea, the UK, or any other part of the world.

A scam aimed at Android users in South Korea and the United Kingdom is attempting to obtain their cryptocurrency login details.

According to a report by McAfee, there’s been an increase in malicious software designed to pilfer cryptocurrency login information from Android users. This malware specifically focuses on capturing the mnemonic phrases that represent the private keys, often by taking screenshots or images of them.

The malware known as SpyAgent employs Optical Character Recognition (OCR) to scan data stored on Android devices, specifically media files. This technology, widely used across various devices, enables these devices to extract text from such files. However, it’s not just images that SpyAgent targets; it can also gather information from text messages and chats. Moreover, this malware’s purpose is to steal sensitive data, which could potentially enable its creators to seize crypto users’ funds.

McAfee’s investigation uncovered the methods used by the criminals responsible for SpyAgent malware infections on mobile devices. They are utilizing phishing schemes distributed through social media platforms and sending fraudulent links via SMS messages. These posts and texts frequently promote reliable applications such as banking, government services, streaming TV, and utility providers. The sites linked from these deceptive connections appear to be authentic, making it simple for users who click on the links to download the applications. However, the APK files (Android application packages) downloaded from these websites install SpyAgent malware instead. Once installed, the malware takes control of the phones to search for text messages, images, device details, and contacts.

SpyAgent Targeting Android Users in South Korea and the UK

McAfee discovered that 280 deceptive apps were used for spreading malware, mainly focusing on South Koreans through phishing attacks. Yet, further investigation uncovered that the perpetrators behind SpyAgent have been launching campaigns in the United Kingdom as well. This discovery highlights the fact that these threat actors are broadening their interests not only demographically but geographically too. The shift towards the UK suggests a strategic effort by the attackers to widen their operations, targeting potential new user groups with tailored versions of the malware in the local market.

In August, two different types of malicious software threats were exposed – one specifically aimed at Mac systems and another designed to attack Windows-based devices.
