We discovered a cyberespionage campaign we have named Project Spy infecting Android and iOS devices with spyware by using the coronavirus disease (Covid-19) as a lure.

A recently discovered watering hole attack has been targeting iOS users in Hong Kong. The campaign uses links posted on multiple forums that supposedly lead to various news stories. While these links lead users to the actual news sites, they also use a hidden iframe to load and execute malicious code. The malicious code contains exploits that target vulnerabilities present in iOS 12.1 and 12.2. Users that click on these links with at-risk devices will download a new iOS malware variant, which we have called lightSpy.

Our findings homed in on known vulnerabilities, IoT botnets with top vulnerability detections, and devices that are affected.
From April 1 to May 15, we observed that 30 percent of home networks had at least one vulnerability detection. A detection would mean that we found at least one connected device being accessed through a vulnerability in the network. Our scanning covered different operating systems (OSs), including Linux, Mac, Windows, Android, iOS, and other software development kit (SDK) platforms.
We covered iXintpwn/YJSNPI in a previous blog post and looked into how it renders an iOS device unresponsive by overflowing it with icons. This threat comes in the form of an unsigned profile that crashes the standard application that manages the iOS home screen when installed. The malicious profile also exploits certain features to make iXintpwn/YJSNPI more difficult to uninstall.
We recently discovered a new variant of iXintpwn/YJSNPI (detected by Trend Micro as IOS_YJSNPI.A) that uses a signed profile to conduct different attacks compared to its predecessor. IOS_YJSNPI.A is extracted from either of the two app stores—hxxp://m[.]3454[.]com and hxxp://m[.]973[.]com. Based on our analysis, this new variant’s main purpose is not to damage users’ operating systems, but to lure users into downloading repackaged apps.
