Cryptolocker Like Ransomware Spreads to Android Devices
Quick, pay this fine or the FBI will arrest you! That's how a new type of Android ransomware is tricking people into paying up. Once installed, the malware, dubbed "Koler.A," locks up the phone, preventing users from accessing the home screen and effectively holding the phones ransom until users pay $300. "Koler.A," first detected Sunday (May 4) by the pseudonymous French security blogger Kafeine, is one of the first discovered examples of Android ransomware, and the first known "police Trojan" for Android. Fortunately, its bark is worse than its bite.
Koler.A spreads using malicious traffic-distribution systems (TDS) — short pieces of software placed on websites, often through ads, that redirect visitors to other sites. Malicious TDS's detect visitors' browsers, operating systems and countries of residence, and redirect them to malicious Web pages with embedded browser exploit kits tailored to each victim. In the case of Android devices, the visitor's browser will be redirected to a fake pornography website that will try to trigger a drive-by download (which won't work if the device is set to reject any app from outside the Google Play store).
However, even if the download succeeds, the Android user will have to manually approve the app's installation. The malware creators have to trick users into thinking the malicious app is harmless. How do the ransomware creators trick these discerning porn site visitors? By promising more porn, of course! Kolar.A presents itself as BaDoink, a video player app that often needs to be installed to view streaming porn on mobile devices.

So if I get this right, in order to get "infected" with this ransomware you have to:
1: Somehow ended up in a fake pornography website from your phone. Okay not that hard.
2: Initiate a download or if its initiating automatically let it continue. If its not blocked by the OS if "Unknown Sources" option in "Security" inside the android "Settings" its checked that is.
3: Manually install this fake app whatever its name is to get "infected".
I can't think what to write as a conclusion to the above without being offense or sound like a prick. I think most will get what I'm saying.
I must admit sometimes it happened to myself that some "crapware" app manage to bypass me and get downloaded but was either immediately cancelled or deleted if it managed to be downloaded.
It's not only that. By reading this article, I understood that if you have other non-Play-Store sources enabled, they might use some exploit in case you have unpatched browser, which is not that unlikely.
Phone software is frequently insecure, so we might have reached a point in time, where installing antivirus software becomes a good practice.

Believe me, you wouldn't be laughing even if something similar didn't happened to you...
About 10 days ago we had a (middle age female) client, she brought us her Acer Aspire One 752 netbook with Windows 7 Home Premium 64bit she was using for years without any kind of protection: no anti-virus (some idiot who did maintenance of that netbook earlier even disabled Windows Defender), no anti-spyware... nothing!
Few days before she had noticed that wallpaper has changed: black screen with message that her computer is infected with BitCrypt v2.0 (bug fixed) malware, all files (pictures, documents...) are cripted blah, blah... and if she wants to have them back she has to follow procedure in some *.txt file, install Tor browser, go to some link and insert ID of her computer...blah...blah...
At the end the only solution for geting back thousands of her pictures and documents is to pay 230$ ransom and then she will receive program and password on her e-mail with procedure how to unlock all her personal files on HDD of that Acer netbook. There is no other solution at this moment, BitCrypt v2.0 (bug fixed) encription is currently impenetrable...
She was so depressed because of thousands of pictures/memories she can't see anymore and I had shared her pain because she wasn't able to pay a 230$ ransom, but... But when I asked her: "...do you know you aren't using any kind of protection software on that netbook, and you are using that netbook for years!?" ...she answered me: "..yes, I know that...". "... WTF is wrong with you lady, there is dozens of free anti-virus and anti-spyware software out there for personal use!?..." went through mi mind after her stupid answer.
How come anyone be so stupid to use something for years without any kind of protection or backup solution (e.g. external USB HDD), store all kinds of memories and personal files on that thing and expect nothing will happen, ever?!
At the same time I felt sorry and I was mad at her because of her stupidity...
Just to add one more thing: she was blonde....

I think the below quoted text from the article is pretty clear. Its just an app to be downloaded and you need to install it in order to get "infected".

That's crossing the line, what kind of horrible person puts up a bad link to pornography!

All this could be avoided if the companies running the adds would spend the money and effort to check their adds for malware before releasing them to the public. They should be held responsible for this. That said, you have to be incredibly stupid to fall for this one in particular (other PC based malware does not require the user to confirm things though).

Bro,u dont need antivirus i tested some of them. Thoose free avast software does more harm than help... Ofc. Why would you so desperate to watch porn on your tablet or phone? 2nd still if you think that only anti-virus deffend yourself from viruses than you are wrong. Dont click on suspicius links. Dont download something if you are not so sure about it. Instead go and Check the file/site with https://www.virustotal.com/ Even some of those free antiv-virus programs cant clean up most of things will come back always.
Does anybody remember the Microsoft update which was draw-back from update? Becouse it wouldnt let the windows startup,it would get bluescreen or something. There was similiar update for one of this antiviruses,which wouldnt let user go to internet,user was forced to download from other pc the update fix,or to delete the software. around 8-10years ago i bought a pc(i mean my parents) but the point is,i installed there a NOD32(which every one talked how good antivirus was),2day later i was downloading some crack for game. 1st thing he stops the download,2nd he needs restart to clean the trojan. When it restarted it keep poped up that he needs a restart to clean the virus. You couldnt enter to registry neather to my computer. Ok,it was fresh pc no neccesery problem to reinstall,and to remember to dont install **** antivirus programs which cant do nothing. My personal favorit is kaspersky,but for live protections you have to pay license. But the virus remowal tool is free for using.

Ha. While malware hunting I've found that very same "scary pointing Obama" image verbatim on a separate website which locks the web browser till you pay a fine. I saved them though, they're great.
Here guys, enjoy.

Crypting services. See: https://krebsonsecurity.com/2014/05/antivirus-is-dead-long-live-antivirus/
Meaning, even if she had an anti-virus it doesn't mean she would of been protected. I'm far from saying AVs are worthless, I'm just saying it might not have protected her anyway. A more solid protection is backing **** up on Blu-ray disks.

Also, I think it's all related to this: http://www.bleepingcomputer.com/virus-removal/remove-mandiant-usa-cyber-security-ransomware
So they've just moved from browser ransomware to android.

Unfortunately some don't have much of choice. Obviously among the top 3 OSes(Android, WPhone, iOS) personally I "need" to choose android.
Why? I always liked big phones. Since my first "smartphone" HTC TyTn back then, I only bought big phones since. I just love the screen estate. I currently own a Galaxy Mega 6.3 i9200(wanted the GN3 but was low on cash at that time so hopefully I will get the GN4 with the possible waterproof body).
So, iPhones are too "small" for me and WPhone's aren't so "advanced" yet imo although I like their whole design/OS but I already got way too familiar with Android.
Also I really don't want to start a argument on the next phrase, but if Apple had a well priced iPhone with a 5-5.5" screen in the last 2 years I would probably had gone with them.

It's fine man, no worries. A linux or OS X guy would probably lol @ me for using windows.

While the "malware" targeted to Android is growing, and there is a lot of stuff out there- Android isn't insecure. You have SElinux support combined with most apps requiring permissions be set. There are plenty of decent AVs available for Android too.
If anyone wants some ideas of security software/setups for Android, give this a look over: http://www.wilderssecurity.com/threads/what-is-your-android-security-setup-these-days.359465/

Sure no biggie. Just having a chat.
I briefly used Linux in the past and much more extensively Backtrack.
And in all fairness as a veteran windows user for the last 20yrs almost, when I talk with a friend or someone and I hear they use Linux or OSX I give them a weird "look" for a split second and then I remember that there isn't a wrong OS to use.
Each uses what they like/prefer/need.

So if I get this right, in order to get "infected" with this ransomware you have to:
1: Somehow ended up in a fake pornography website from your phone. Okay not that hard.
2: Initiate a download or if its initiating automatically let it continue. If its not blocked by the OS if "Unknown Sources" option in "Security" inside the android "Settings" its checked that is.
3: Manually install this fake app whatever its name is to get "infected".
I can't think what to write as a conclusion to the above without being offense or sound like a prick. I think most will get what I'm saying.
I must admit sometimes it happened to myself that some "crapware" app manage to bypass me and get downloaded but was either immediately cancelled or deleted if it managed to be downloaded.
