We recently discovered several malicious optimizer, booster, and utility apps (detected by Trend Micro as AndroidOS_BadBooster.HRX) on Google Play that are capable of accessing remote ad configuration servers that can be used for malicious purposes, perform mobile ad fraud, and download as many as 3,000 malware variants or malicious payloads on affected devices.Read More

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
We have been detecting a new wave of network attacks since early March, which, for now, are targeting Japan, Korea, China, Taiwan, and Hong Kong. The attacks use Domain Name System (DNS) cache poisoning/DNS spoofing, possibly through infringement techniques such as brute-force or dictionary attacks, to distribute and install malicious Android apps. Trend Micro detects these as ANDROIDOS_XLOADER.HRX.
These malware pose as legitimate Facebook or Chrome applications. They are distributed from polluted DNS domains that send a notification to an unknowing victim’s device. The malicious apps can steal personally identifiable and financial data and install additional apps. XLoader can also hijack the infected device (i.e., send SMSs) and sports self-protection/persistence mechanisms through device administrator privileges.Read More

This Monero-mining Android app’s self-protection and persistence mechanisms include hiding itself from the unwitting user and abusing the Device Administrator feature (a technique typically seen in SLocker Android ransomware).Read More
