WARNING — Malware Found in CamScanner Android App With 100+ Million Users

Beware! Attackers can remotely hijack your Android device and steal data stored on it, if you are using free version of  CamScanner , a highly-popular Phone PDF creator app with more than 100 million downloads on Google Play Store. So, to be safe, just uninstall the CamScanner app from your Android device now, as Google has already removed the app from its official Play Store. Unfortunately, CamScanner has recently gone rogue as researchers found a hidden Trojan Dropper module within the app that could allow remote attackers to secretly download and install malicious program on users' Android devices without their knowledge. However, the malicious module doesn't actually reside in the code of CamScanner Android app itself; instead, it is part of a 3rd-party advertising library that recently was introduced in the PDF creator app. Discovered by Kaspersky security researchers, the issue came to light after many CamScanner users spotted suspicious behavior and posted neg

Do you believe that just because you have downloaded an app from the official app store, you're safe from malware? Think twice before believing it. A team of security researchers from several security firms have uncovered a new, widespread botnet that consists of tens of thousands of hacked Android smartphones. Dubbed WireX, detected as "Android Clicker," the botnet network primarily includes infected Android devices running one of the hundreds of malicious apps installed from Google Play Store and is designed to conduct massive application layer DDoS attacks. Researchers from different Internet technology and security companies—which includes Akamai, CloudFlare , Flashpoint, Google, Oracle Dyn, RiskIQ, Team Cymru—spotted a series of cyber attacks earlier this month, and they collaborated to combat it. Although Android malware campaigns are quite common these days and this newly discovered campaign is also not that much sophisticated, I am quite impressed wit

A new Android-rooting malware with an ability to disable device' security settings in an effort to perform malicious tasks in the background has been detected on the official Play Store. What's interesting? The app was smart enough to fool Google security mechanism by first pretending itself to be a clean app and then temporarily replacing it with a malicious version. Security researchers at Kaspersky Lab discovered a new piece of Android rooting malware that was being distributed as gaming apps on the Google Play Store, hiding behind puzzle game " colourblock ," which was being downloaded at least 50,000 times prior to its removal. Dubbed Dvmap , the Android rooting malware disables device's security settings to install another malicious app from a third-party source and also injects malicious code into the device system runtime libraries to gain root access and stay persistent. "To bypass Google Play Store security checks, the malware creators used

Do you like watching funny videos online? I am not kind of a funny person, but I love watching funny videos clips online, and this is one of the best things that people can do in their spare time. But, beware if you have installed a funny video app from Google Play Store. A security researcher has discovered a new variant of the infamous Android banking Trojan hiding in apps under different names, such as Funny Videos 2017 , on Google Play Store. Niels Croese, the security researcher at Securify B.V firm, analyzed the Funny Videos app that has 1,000 to 5,000 installs and found that the app acts like any of the regular video applications on Play Store, but in the background, it targets victims from banks around the world. This newly discovered banking Trojan works like any other banking malware, but two things that makes it different from others are — its capability to target victims and use of DexProtector tool to obfuscate the app's code. Dubbed BankBot , the banking

Bought a brand new Android Smartphone? Do not expect it to be a clean slate. At least 36 high-end smartphone models belonging to popular manufacturing companies such as Samsung, LG, Xiaomi, Asus, Nexus, Oppo, and Lenovo, which are being distributed by two unidentified companies have been found pre-loaded with malware programs. These malware infected devices were identified after a Check Point malware scan was performed on Android devices. Two malware families were detected on the infected devices: Loki and SLocker. According to a blog post published Friday by Check Point researchers, these malicious software apps were not part of the official ROM firmware supplied by the smartphone manufacturers but were installed later somewhere along the supply chain, before the handsets arrived at the two companies from the manufacturer's factory. First seen in February 2016, Loki Trojan inject devices right inside core Android operating system processes to gain powerful root privi

Here's some bad news for Android users again. Certain low-cost Android smartphones and tablets are shipped with malicious firmware, which covertly gathers data about the infected devices, displays advertisements on top of running applications and downloads unwanted APK files on the victim's devices. Security researchers from Russian antivirus vendor Dr.Web have discovered two types of downloader Trojans that have been incorporated in the firmware of a large number of popular Android devices operating on the MediaTek platform, which are mostly marketed in Russia. The Trojans, detected as Android.DownLoader.473.origin and Android.Sprovider.7 , are capable of collecting data about the infected devices, contacting their command-and-control servers, automatically updating themselves, covertly downloading and installing other apps based on the instructions it receives from their server, and running each time the device is restarted or turned on. The list of Android devic

While some payment card companies like Mastercard have switched to selfies as an alternative to passwords when verifying IDs for online payments, hackers have already started taking advantage of this new security verification methods. Researchers have discovered a new Android banking Trojan that masquerades primarily as a video plugin, like Adobe Flash Player, pornographic app, or video codec, and asks victims to send a selfie holding their ID card, according to a blog post published by McAfee. The Trojan is the most recent version of Acecard that has been labeled as one of the most dangerous Android banking Trojans known today, according to Kaspersky Lab Anti-malware Research Team. Once successfully installed, the trojan asks users for a number of device's permissions to execute the malicious code and then waits for victims to open apps, specifically those where it would make sense to request payment card information.
