This new XLoader variant poses as a security app for Android devices, and uses a malicious iOS profile to affect iPhone and iPad devices. Aside from a change in its deployment techniques, a few changes in its code set it apart from its previous versions.Read More
We discovered several beauty camera apps (detected as AndroidOS_BadCamera.HRX) on Google Play that are capable of accessing remote ad configuration servers that can be used for malicious purposes. Some of these have already been downloaded millions of times, which is unsurprising given the popularity of these kinds of apps.Read More
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.Read More
The mobile threat landscape isn’t just rife with information stealers and rooting malware. There’s also mobile ransomware. While it seems they’re not as mature as their desktop counterparts, what with the likes of WannaCry and Petya, the increasing usage of mobile devices, particularly by businesses, will naturally draw more cybercriminal attention to this type of threat.
Take for instance mobile ransomware on the Android platform. The variants we detected and analyzed during the fourth quarter of last year were thrice as many compared to the same period in 2015. And indeed, the surge is staggering. We already had over 235,000 detections for Android mobile ransomware in the first half of 2017 alone—that’s 181% of detections for all of 2016.Read More
