New Android malware poses as popular game, but enlists phones into botnet

The malware has evaded Google Play’s malware scans for weeks.

At least five instances of the app have so far been able to evade Google Play’s malware scans for almost a month, since it was first submitted to the app store.

When the user installs the app, it will automatically join a botnet — a network of devices controlled by an attacker — which disguise ad clicks to generate money


Marshmallow Security

How to find your patch level.

The Security Patch Level can only be found on devices running Android Marshmallow.

The good news for Android Marshmallow (6.0) users is that the release includes very important improvements that go a long way to protect your device. One addition allows you to quickly find out the security patch level on your smartphone or tablet.  It all started with the Stagefright vulnerability. Once the dust settled from that disaster, Google (and Samsung) made a promise to start rolling out monthly security updates. To that end, they decided to include a field in the device settings that would list for users to see when the last security patch was applied to the operating system.

Sure signs you’re hacked . . . .

CSO logo

“The hope of an anti-malware program that can perfectly detect malware and malicious hacking is pure folly. Keep an eye out for the common signs and symptoms of your computer being hacked as outlined above. And if you are risk-adverse, as I am, always perform a complete computer restore with the event of a breach. Because once your computer has been compromised, the bad guys can do anything and hide anywhere.”

Avoid The Pileup

Sad AndroidJack Wallen introduces you to a must-have application to protect your Android devices from the new pileup flaw.

Those who can create malware, will create malware — no matter how sneaky they have to be to do so. The latest craze is called pileup malware. The gist of this is a seemingly innocent and harmless piece of software is installed on your device (even with the stamp of approval from your malware scanner). The initial install requires little to no permissions, so it looks perfectly safe. The problem comes when it’s time to update that software. Without needing your approval, the software will upgrade its own permissions, giving it much more access than it originally had — there’s the pileup (and the rub). You now have an official piece of harmful malware on your machine.
