The GhostBat RAT campaign employs sophisticated malware distribution techniques, utilizing infection vectors such as WhatsApp, SMS with shortened URLs, GitHub-hosted APKs, and compromised websites to deliver malicious Android droppers. These droppers utilize multi-stage workflows, ZIP header manipulation, and string obfuscation to evade detection. The malware includes tools for stealing banking credentials and cryptocurrency miners, directing victims to phishing pages resembling the mParivahan app to collect sensitive information. SMS messages with banking keywords are exfiltrated to command and control servers, while incoming messages may be forwarded for OTP harvesting. Device registration occurs through a Telegram bot named GhostBatRat_bot. In July 2024, Android malware impersonating Regional Transport Office applications was documented, designed to steal contacts and SMS messages. Observations from September 2025 revealed over forty samples propagating through WhatsApp and SMS, ultimately delivering a malicious version of the mParivahan app. The malware initiates phishing activities by requesting SMS permissions and harvesting banking credentials. VirusTotal detections for the malware remain low due to its multi-layered dropper mechanisms and obfuscation techniques. The architecture of GhostBat RAT features multi-stage dropper workflows, native binary packing, and heavy string obfuscation. The first-stage dropper verifies device architecture and manufacturer, while subsequent stages decrypt and execute payloads, including a cryptominer library and a malicious APK for data theft. Victims encounter a counterfeit Google Play update page, leading to the installation of the malicious APK, which requests SMS permissions and presents a phishing interface. Users are prompted to enter their UPI PIN into a fake payment flow, which forwards the PIN to a Firebase endpoint. The campaign highlights the need for careful SMS permission management and vigilance against shortened URLs to combat emerging Android malware threats.

Macs have become increasingly attractive targets for cybercriminals due to their rise in popularity, now ranking as the fourth most popular personal computer brand. A comprehensive test conducted by Macworld evaluated macOS's built-in security against over 130 known malware samples. The findings indicated that while macOS can be vulnerable if users ignore warnings, its built-in protections are generally effective. Testers were able to install malware by bypassing security prompts, but the overall conclusion was that vigilant users who heed macOS warnings can effectively protect themselves from most malware threats. Users who primarily download from the Mac App Store and pay attention to security prompts are generally safe.
