Background for this topic.
Malware is software intentionally created or modified to perform unauthorized or harmful actions on a computer, device, or network. The term covers distinct families and functions, including viruses, worms, trojans, spyware, botnet clients, and ransomware; a single sample may combine several capabilities. Its behavior—not its label—determines the security concern: it may execute code, persist, alter or encrypt data, steal credentials, or provide unauthorized remote access.
For practitioners, malware reporting is most useful when it identifies the family or tool conservatively and provides evidence such as affected platforms, samples, infrastructure, or observed behavior. Defenses include promptly patching vulnerable software, restricting execution and privileges, monitoring endpoints and networks, maintaining tested backups, and isolating suspected systems for analysis. Detection should use behavior and verified indicators rather than names alone, since variants change. If malware processes personal or regulated data, investigations should also address privacy, evidence preservation, and applicable reporting obligations.
Researchers Say PromptSpy Automates Persistence on Infected DevicesA newly discovered Android malware strain, "PromptSpy," is using Google's Gemini generative artificial intelligence model to automate part of its persistence mechanism, marking what researchers describe as the second known case of AI-driven mobile malware.
$20M Stolen Last Year in Malware-Driven Jackpotting Attacks, Warns FBIMalware-wielding criminals "jackpotted" ATMs across the United States last year to walk away with $20 million thanks to "cash-out" attacks. Tracking that collective haul, the FBI said such attacks are on the rise, and urged operators to implement a range of physical and hardware-level defenses.
New Trojan May Soon Be Offered for Sale to Criminal UndergroundSecurity researchers warn of "Massiv," an Android Trojan - disguised as an IPTV app - targeting users who sideload streaming apps. The malware enables screen capture, overlays and credential theft - and may soon be marketed on criminal underground forums as malware as a service.
Malware Campaign Uses Lures With Positive Portrayal of Anti-Tehran ProtestsA new malware campaign is using a positive-sounding report into the recent protests in Iran, accompanied by real photos and videos, as lures in an apparent cyberespionage operation designed to conduct surveillance of dissident researchers and global communities, warn security researchers.
