We found hundreds of the fake apps on iOS App Store and Google Play, with descriptions that are inconsistent with their content. While the apps’ descriptions varied, they share the same suspicious behavior: They could transform into gambling apps that may get banned for violating local government regulations and app store policies.Read More

The 2018 mobile threat landscape had banking trojans that diversified their tactics and techniques to evade detection and further monetize their malware — and in the case of the Anubis Android malware, retooled for other malicious activities. Anubis underwent several changes since it first emerged, from being used for cyberespionage to being retooled as a banking malware, combining information theft and ransomware-like routines. In mid-January of 2019, we saw Anubis use a plethora of techniques, including the use of motion-based sensors to elude sandbox analysis and overlays to steal personally identifiable information.
The latest samples of Anubis (detected by Trend Micro as AndroidOS_AnubisDropper) we recently came across are no different. While tracking Anubis’ activities, we saw two related servers containing 17,490 samples.Read More
We uncovered a cyberespionage campaign targeting Middle Eastern countries. We named this campaign “Bouncing Golf” based on the malware’s code in the package named “golf.” The malware involved, which Trend Micro detects as AndroidOS_GolfSpy.HRX, is notable for its wide range of cyberespionage capabilities. Malicious codes are embedded in apps that the operators repackaged from legitimate applications. Monitoring the command and control (C&C) servers used by Bouncing Golf, we’ve so far observed more than 660 Android devices infected with GolfSpy. Much of the information being stolen appear to be military-related.
The campaign’s attack vector is also interesting. These repackaged, malware-laden apps are neither on Google Play nor popular third-party app marketplaces, and we only saw the website hosting the malicious apps being promoted on social media when we followed GolfSpy’s trail. We were also able to analyze some GolfSpy samples sourced from the Trend Micro mobile app reputation service.Read More
We discovered a malware family called Maikspy — a multi-platform spyware that can steal users’ private data. The spyware targets Windows and Android users, and first posed as an adult game named after a popular U.S.-based adult film actress. Maikspy, which is an alias that combines the name of the adult film actress and spyware, has been around since 2016.
Multiple Twitter handles were found promoting the Maikspy-carrying adult games and sharing the malicious domain via short links.Read More
Trend Micro detected a new variant of Android Remote Access Tool (AndroRAT) (identified as ANDROIDOS_ANDRORAT.HRXC) that has the ability to inject root exploits to perform malicious tasks such as silent installation, shell command execution, WiFi password collection, and screen capture. This AndroRAT targets CVE-2015-1805, a publicly disclosed vulnerability in 2016 that allows attackers to penetrate a number of older Android devices to perform its privilege escalation.Read More
