New Android “ransomware” insists you must pay a $300 fine because you watched awful porn

"Ransomware" is one of the mobile malware sub-genres in circulation. It eats up your screen real estate with a warning that you somehow engaged in horrible crime activity and therefore must pay a ransom. The latest contender to emerge in this rare niche is Android-Trojan.Koler, and boy, is it a nasty one! As its name not-so-subtly suggests, it creeps up on Android devices and is as smart as to use geolocation to properly "locate" its alarm bells to the user's actual country and relative crime burreay. It accuses you of watching banned pornography and demands a $300 ransom, which should be paid off through covert payment mechanisms like Paysafecard and uKash. Thankfully, real-life offenders rarely get away this easy.


The ransomware works by preventing users from accessing their phones' home-screens and making it impossible to browse menus and use apps as normally. BitDefender e-threat analyst Bogdan Botezatu explained that Koler.A opens a browser view that stays on top of other apps. Users can press Home and return to the home-screen, but a 5-second timer brings back the spam on top.


Luckily, this trashy piece of code isn't being distributed via the Google Play Store, which saw its share of malware-related mishaps lately. The way it reaches your Android device is by installing itself when browsing certain porn sites. These sites claim that the malware's download is actually an APK for a video player used for premium access. We don't have a list of websites to serve, but as an Android user, you should be aware that downloading APK's from sketchy websites is a sure way to get infected.

Well... people downloading APK files from shady websites AND having the Unknown Sources setting checked! for this to be able to happen, almost deserve it...

Most people don't even know how to manually install APKs... the ones that knows should also use Google Installer which scan the APK before installing... and finally who the hell install APKs getting download from porn websites?

BTW, PHONEARENA.COM has intended to download Mobogenie.APK apps to my phone in the past... just so people know...

It's actually a common trick used for Microsoft computers as well.

small price (only some dumb people pay) in exchange for the best and most versatile mobile OS.

btw iOS is no king in security... specially on V. 7

Best and most versatile is subjective and to think otherwise is pure ignorance. Has iOS had security issues? Yes but Apple is super quick to patch any vulnerabilities up.

Well if you jailbreak IOS to make it usuable this is possible. Basically use the protected jail OS or take small chances with Freedom OS. It's like the war on terror, terrorism almost never happens, but people are ready to get rid of their freedoms for it.

"Freedom OS"? That's rich. Bloatware that you have to root to get rid of, Google apps that run in the background without ever getting opened, constant reminders about security software, Google Hangouts being jammed in your face through notifications, even if you set an alternate messaging app, and constant reminders to select which keyboard you want to use after you install and select another keyboard from Play. Sounds like freedom to me.

Add into that data mining on a scale that makes the NSA look like two-bit chumps, and I would say you need to take a trip to Dictionary.com for some definition help. The Google world is not, and never will be, about your "freedom." It's about your DATA, which you use to pay for your device a second time.

How could Google patch the stupidity of users who download APKs from sketchy websites?

What is subjective is personal needs and taste... But versatility can be measured. Features and functions can be measured. And popularity can be measured...

Subjectively it is the best for me and the majority of smartphone users... Objectively it is the most versatile, customizable, fullest of features. That is a fact

Have ever used a Windows computer? They are the king of Trojans, malware, spyware...etc. Luckily, I know how to avoid that stuff and when I do see it I remove it. I like an OS that is open and mod friendly and I do realize that it cones with a risk. Look at iPhones...closed OS and they still have security issues...

never once had a virus on windows or android. If you are stupid you will get a virus on IOS. Don't install anything you don't trust and you won't have a virus. Common sense.

I suppose its pointless to mention safe-mode, since the person affected would be too stupid to know about it and probably too embarrassed to show it to someone who does.

Pr0n on a phone is almost as pathetic as whacking it to scrambled cable channels. And even if your phone is your only method to invest in your spank bank, there's plenty of safe ways to make a deposit/withdrawl. You've got to be pretty dumb/naive/desperate to just go anywhere and download anything.

This sort of ransomware should be classified as "terrorism" so there is a military solution.
