Researchers at Avast Threat Labs say that more than 100 different low-cost Android devices from manufacturers like ZTE, Archos, and myPhone come with malware pre-installed. Users in more than 90 countries, including the US, are said to be infected. The good news is there’s a fix.
According to the report, this adware variant has been in the wild for three years. It’s called “Cosiloon” and was first noticed by Dr. Web in 2016. Because it’s located in the device’s firmware, it’s extremely difficult to remove. Avast has detected its presence on 18,000 of its users’ devices, so far.Read more
An advanced type of malware can spy on nearly every Android smartphone function and steal passwords, photos, video, screenshots and data from WhatsApp, Telegram and other apps. "ZooPark" targets subjects in the Middle East and was likely developed by a state actor, according to Kaspersky Lab, which first spotted and identified it.
ZooPark has evolved over four generations, having started as simple malware that could "only" steal device account details and address book contacts. The last generation, however, can monitor and exfiltrate keylogs, clipboard data, browser data.Read more
Google has long struggled with how best to get dozens of Android smartphone manufacturers—and hundreds of carriers—to regularly push out security-focused software updates.
But when one German security firm looked under the hood of hundreds of Android phones, it found a troubling new wrinkle: Not only do many Android phone vendors fail to make patches available to their users, or delay their release for months; they sometimes also tell users their phone's firmware is fully up to date, even while they've secretly skipped patches.Read more
Security researchers have discovered a massive continuously growing malware campaign that has already infected nearly 5 million mobile devices worldwide.
Dubbed RottenSys, the malware that disguised as a 'System Wi-Fi service' app came pre-installed on millions of brand new smartphones manufactured by Honor, Huawei, Xiaomi, OPPO, Vivo, Samsung and GIONEE—added somewhere along the supply chain. All these affected devices were shipped through Tian Pai, a Hangzhou-based mobile phone distributor, but researchers are not sure if the company has direct involvement in this campaign.Read more
Smartphone users are just as vulnerable to cryptocurrency mining hijacks as their PC counterparts, and sometimes on a dramatic scale.
Malwarebytes has detailed a "drive-by" mining campaign that redirected millions of Android users to a website that hijacked their phone processors for mining Monero. While the exact trigger wasn't clear, researchers believed that infected apps with malicious ads would steer people toward the pages. And it wasn't subtle -- the site would claim that you were showing "suspicious" web activity and tell you that it was mining until you entered a captcha code to make it stop.Read more
A new botnet that distributes malware for mining Monero cryptocurrency has emerged, infecting Android devices through a port linked with a debugging tool for the OS, according to researchers at Qihoo 360 Netlab.
Dubbed ADB.Miner by 360 Netlab, the botnet is gaining entry to Android devices–mostly smartphones and TV boxes–through port 5555, which is associated with Android Debug Bridge, a command-line tool that is used for debugging, installing apps and other purposes. ADB typically communicates with devices via USB, but it’s also possible for it to use wifi with some setup, according to Android documentation.Read more
Sega has said it is looking into claims that a trio of its Sonic games for Android are leaking personal data.
Security company Pradeo said late last week that it had discovered the Android games -- Sonic Dash, Sonic the Hedgehog Classic, and Sonic Dash 2: Sonic Boom -- were leaking user location data and device info. Based on the download ranges offered by the Play Store, collectively the leaks could impact between 120 million and 600 million users. Among the tracking and advertising issues, the security firm also said it found two issues that could result in man-in-the-middle attacks, and a bagful of others that could potentially lead to encryption weakness and denial of service.Read more
Malware which aims to steal Facebook login credentials and also aggressively displays pop-up adverts has been uncovered targeting Android users via the Google Play store -- and may have been downloaded by hundreds of thousands of unwitting victims.
Dubbed GhostTeam after strings in the code by the analysts at security company Trend Micro which uncovered it, the malware was first published in April 2017 and was disguised in the official Android marketplace as utility apps, performance boosters, and social media video downloaders.Read more
Researchers have identified a powerful new Android malware strain called Skygofree capable of eavesdropping on WhatsApp messages, siphoning private data off phones and allowing adversaries to open reverse shell modules on targeted devices, giving attackers ultimate remote control.
Researchers said the malware was developed three years ago and has evolved significantly since then to include 48 unique commands in it most recent iteration. Several of those features have never been seen before in Android malware, according to researchers at Kaspersky Lab who discovered the Skygofree strain last year and disclosed its findings Tuesday.Read more
If you happen to have an old Android device lying around and a reason to worry about people messing with your business, Edward Snowden has an app for that.
Haven is an open-source project that Snowden developed in conjunction with Freedom of the Press Foundation and Guardian Project. You can find directions and links for downloading and installing it on the latter organization's Github page. This isn't your typical security app. Haven doesn't lock down a single device or prevent tampering; instead, it repurposes an Android device — an old, unused one, preferably — and, using an assortment of built-in sensors, turns it into a multi-functional security gadget.Read more
