Researchers have identified a new spyware campaign targeting Iranian users of Android VPN applications, specifically a revamped version of DCHSpy, which disguises itself as legitimate VPN services like Starlink. This campaign began shortly after the Israel-Iran conflict and coincided with increased VPN usage among Iranians facing internet restrictions. DCHSpy can collect sensitive user data, including WhatsApp messages, contacts, SMS, files, location information, call logs, and has the ability to record audio and capture images. The spyware is maintained by the hacking group MuddyWater, linked to Iran's Ministry of Intelligence and Security, and has been enhanced with new functionalities. Malicious VPN services EarthVPN and ComodoVPN are being used to spread the malware, following the previous use of HideVPN. Experts warn that hackers are distributing malicious APKs through trusted platforms like Telegram, increasing risks for Iranian citizens. Security analyst Azam Jangrevi advises caution when downloading apps, recommending verified app stores and mobile security solutions to detect threats like DCHSpy. For high-risk professionals, she suggests using hardware-based security keys and vetted encrypted messaging applications.

A new strain of malware called Octo2 is spreading across Europe, targeting Android phone users. Discovered by ThreatFabric, Octo2 disguises itself as popular applications like Google Chrome and NordVPN. Once installed, it allows hackers to control the device, capture on-screen activity, intercept messages, and log keystrokes, facilitating identity theft and phishing schemes. The malware is primarily distributed through unofficial app stores and currently affects users in Italy, Poland, Moldova, and Hungary, with potential for global spread. Octo2 is believed to be a successor to the original Octo trojan, which had a wide reach before its source code was leaked, prompting the development of Octo2. Users are advised to download apps only from the Google Play Store and remain vigilant about app permissions and developer credentials. Google Play Protect automatically protects Android users from known versions of this malware.
