The bottom line is you can never be certain if your Android device is infected or not, so the best way to stay safe is to install high-profile apps and avoid the questionable ones. What's even worse is that malware developers find new ways to pass Google Play Store's security protections more often than ever before. Usually spyware apps are extensions that are installed by adware programs that have been downloaded from the internet. ExpensiveWall is a very tricky malware that's hardly detectable by standard (read free) security solutions available in the Google Play Store. The ExpensiveWall malware was packed inside wallpaper apps, which allowed it to escape Google Plays built-in anti-malware protections. ![]() Well, there's really no way to stay protected as long as you don't pay attention to what permissions an app requests before being installed. Unfortunately, the malware infected at least 50 apps on Google Play, which were downloaded between 1 million and 4.2 million times before they were removed. Unfortunately, many Android users grant these permissions without thinking, which is probably one of the reasons it propagated so fast in the first place. If granted, the malware will start sending premium SMS messages and register users for other paid services that don't exist without the user's knowledge.Īlthough these permissions are pretty common for certain types of apps, there's absolutely no reason for a wallpaper app to request SMS permission or even internet access for that matter. “Monokle is a great example of the larger trend of enterprises and nation-states developing sophisticated mobile malware that we have observed over the years,” the researchers noted in a blog post.Since ExpensiveWall is “packed” inside an Android app, it will ask the user for several common permissions, such as SMS and internet access. The spyware can harvest and exfiltrate data from many popular applications record users’ device screens to capture their PINs, patterns and passwords steal contacts, call histories, browser histories and calendar information record calls and local audio capture user passwords of websites retrieve emails, take screenshots, track the location of a device and more. That’s a unique feature, according to the researchers.Īfter that, Monokle’s features read like a shopping list of just about every known form of surveillance. In its first stage, the spyware enables so-called man-in-the-middle attacks by allowing those behind it to install their own malicious certificates on the infected device. Once a user installs the fake but functional app, Monokle gets to work. Some of the fake apps found included those for Skype, Signal and Pornhub. Many of the apps discovered by the researchers primarily targeted users in the Caucasus region and well as users in and around Syria, but some apps popular in the west were found copied and trojanized as well. ![]() That means the victims are not aware that they have malicious apps and because the apps work, they’re far less unlikely to uninstall them. Following a recent trend in malware, the trojanized apps operate as intended, with the spyware operating in the background. The infection path for Monokle is trojanized versions of what are designed to look like legitimate apps. ![]() The spyware toolset, which is believed to have been developed as far back as 2015, was first observed in the wild in 2016, with infections peaking in 2018, but until recently it had not been identified. The efforts were directed against individuals in Iran and 12 other countries, including the UK and US, Check Point said. Iran is running two surveillance operations in cyber-space, targeting more than 1,000 dissidents, according to a leading cyber-security company. government in connection to alleged interference in the 2016 presidential elections. Iran 'hides spyware in wallpaper, restaurant and games apps'. and dubbed “Monokle,” the spyware is said to have been developed by Russia-based company Special Technology Centre Ltd., which was sanctioned by the U.S. In September, the assortment of trojans detected in Google Play. Spyware is software that is installed on a computing device without the end users knowledge. A new form of Android spyware embedded in functional fake apps is one of the most sophisticated ever seen, according to a new report today.ĭiscovered by cybersecurity researchers at Lookout Inc. Despite Googles efforts to keep its Android store risk free, malicious apps continue to make it past the verification process.
