Lightbulb Ransomware for Android v2

Hi fellas.

I just joined the site after reading vic.laurie's article about the android ransomware scare. It was important for me bacause my dad's phone got hijacked by this malware, but I found out there were a lot of ways to deal with it. The comments section seemed too small for what I wanted to share, so I ended up creating this thread.

Naked Security recommended this:
  • Install a reputable anti-virus program to vet all new apps automatically before they run for the first time.
  • Be cautious of apps you are offered in ads and pop-ups.
  • Stick to Android's default setting of allowing installs from the Google Play store only.
  • Keep off-device backups of your important data.
  • Read our article about using "Safe Mode", just in case you ever need it in a hurry.
The first 4 are pretty obvious tips, but it is the last one who saved my dad's phone. Time is crucial and Safe Mode is the quickest and safest method to stop the ransomware, especially if you cannot connect to a network or if the ransomware managed to affect the PlayStore. Every single phone has Safe Mode options, and there are 3 methods you can use. Try them until you know which one works on your phone. Then, follow the directions provided below the described methods and you'll get rid of that scum very fast.

One thing that called my attention was that my dad's phone did have an antivirus installed, but the definitions were 3 days old and the malware got installed without my dad having the slightest idea (or so he says). Apparently, having an antivirus works only if the latest definitions are installed, otherwise is useless.

It is to be noted that there are many variants of the ransom that you can get, but the base code is the same. Just follow the method above and you will succeed. After that it is up to you to install and antivirus or not, although disabling the 'unknown sources' is a good way to prevent this from happening again.

1. See, that's that "secure Linux" everyone is talking about.

2. No, virus scanners on Android are as pointless as on every other platform (except Linux, probably). Just don't install applications from not trustworthy sources. If you install a software from "somewhere in the internet" without having any clue about who uploaded it for what purpose, no software will ever be able to help you out.

3. Yes, keep backups. I recommend Titanium Backup for that.

The main issue I see almost everywhere is people confusing the terms. Malware is the general name given to any malicious code, program, file, and so on, that can get into a computer. Viruses, trojans, exploits, and such are malware. Malware is a family, not an specific virus.

Android is not as vulnerable as, let's say windoze, but is far from being an unassailable system. Almost every APK you find in the wild is likely to be malicious or manipulated in some way, so yes, antivirus programs are useless in those cases. At least Android is open-source, unlike MacOS or Windoze, so an skilled programer can build new version from scratch and remove any code it considers unfriendly.

The main issue with propietary systems is everything being closed source. The vendor makes you think you are safe, but the ugly truth is you'll never know what kind of code or file library is hidden there.

As long as users are careless or don't have the slightest idea about security, even on a basic level, there will always be a security breach and a huge group of malicious programs ready to sneak in. This ransomware is just the beggining of much worse things to come in the near future.

"Windoze"? Really? Also, welcome to the 21st century.

Open Source makes you think you are safe because anyone can see the source code. Then you'll end up with OpenSSL. Now what exactly is your problem with Windows?

Guys, please refrain from childish behavior. I created this thread for an specific android problem. Don't clog it up. If you have something to say about ransomware or other security-related things, go ahead. Otherwise, don't comment at all.

I don't think this forum's goal is to promote fights or rants about personal preferences.

Couldn't agree more! Nicely said.

UserError, thanks for the info.

I think every android user should know about safemode as different phones have different triggers for entering in safemode, to be on the safe side.

These nasty ransomwares can hit anyone, no one can predict when something like this will happen to them, so taking precautions like what is suggested by Naked-security is very essential, although most people don't take these things seriously until they at-least for once ended up loosing their data.
