Distributing malware through legitimate-looking fake apps and software has always been a go-to attack vector for threat actors. In the past 24 hours, security experts came across two cybersecurity incidents that involved the distribution of a spyware and an information-stealing trojan. While the spyware called CallerSpy was disseminated through apps like ‘Chatrious’ and ‘Apex App,’ the information-stealing trojan used a fake PDF editing program dubbed ‘PDFreader’ for propagation.

Apart from malware attacks, the past 24 hours also saw a new vulnerability affecting 36 Android apps. Dubbed StrandHogg, the flaw is being actively abused in the wild. Once exploited, it can allow malicious apps to camouflage legitimate apps to trick users into handing over sensitive information such as banking or login credentials via screen overlays. The pilfered data can include users’ private photos, GPS locations, contact lists, phone conversations, SMS messages, and phone logs.
