North Korean Spyware Disguised as Android Apps Found on Google Play

Researchers found North Korean spyware disguised as Android apps on Google Play, secretly collecting sensitive data.

 

Researchers have discovered at least five Android apps on Google Play that secretly function as spyware for the North Korean government. Despite passing Google Play’s security checks, these apps collect personal data from users without their knowledge. The malware, dubbed KoSpy by security firm Lookout, is embedded in utility apps that claim to assist with file management, software updates, and even device security. 

However, instead of providing real benefits, these apps function as surveillance tools, gathering a range of sensitive information. KoSpy-infected apps can collect SMS messages, call logs, location data, files, nearby audio, keystrokes, Wi-Fi details, and installed apps. Additionally, they can take screenshots and record users’ screens, potentially exposing private conversations, banking credentials, and other confidential data. All collected information is sent to servers controlled by North Korean intelligence operatives, raising serious cybersecurity concerns. 

Lookout researchers believe with “medium confidence” that two well-known North Korean advanced persistent threat (APT) groups, APT37 (ScarCruft) and APT43 (Kimsuki), are behind these spyware apps. These groups are known for conducting cyber espionage and targeting individuals in South Korea, the United States, and other countries. The malicious apps have been found in at least two app stores, including Google Play and Apkpure. The affected apps include 휴대폰 관리자 (Phone Manager), File Manager, 스마트 관리자 (Smart Manager), 카카오 보안 (Kakao Security), and Software Update Utility. 

On the surface, these apps appear legitimate, making it difficult for users to identify them as threats. According to Ars Technica, the developer email addresses are standard Gmail accounts, and the privacy policies are hosted on Blogspot, which does not raise immediate suspicions. However, a deeper analysis of the IP addresses linked to these apps reveals connections to North Korean intelligence operations dating back to 2019. These command-and-control servers have been used for previous cyberespionage campaigns. 

Google responded to the findings by stating that the “most recent app sample” was removed from Google Play before any users could download it. While this is reassuring, it highlights the ongoing risk of malicious apps bypassing security measures. Google also emphasized that its Play Protect service can detect certain malicious apps when installed, regardless of the source.  

This case serves as another reminder of the risks associated with installing apps, even from official sources like Google Play. Users should always scrutinize app permissions and avoid installing unnecessary applications. A file manager, for example, should not require access to location data. By staying cautious and using reputable security tools, Android users can better protect their personal information from spyware threats.
