Cryptolocker: new malware encrypts your files, demands ransom within 96 hours

What if it sits in stasis for awhile, waiting for me to back up my (already infected) files and fuck up my backup?

You'll know if your files are encrypted as you won't be able to open them. They'll just be noise. Currently it doesn't wait around, and as long as you regularly maintain an offline/disconnected backup you'll be able to restore if the worst happens.

Reading through the reddit through and someone linked something called cryptoprevent, anyone try it?

Seriously? You're going to trust a random app by someone called FoolishTech? smh lol. There are plenty of good recommendations in the thread.


Although it's fairly clear from reading it, it might be handy to have a little summary FAQ in the OP.
 
Yea, I need to make sure my parents work computers have java updated and that backup drives disconnected when not in use.

Thanks OP
 

Some [most?] of those reasons are pretty... subjective, not to mention stupid.

1: If anything, that's a sign of the writer's stupidity.

That is not something that should take two weeks to learn how to use.

2: You can turn notifications off.
3: Happens once a year, at most. And only when they update the UI.
5: You CAN completely disable features.
9: Why would he need an advanced mode if it apparently took him took weeks to work out the "children mode"?

I have McAfee (got a four year sub with my laptop). I'm not saying it's perfect in any means (I have a problem with auto scans that are resource heavy), but most of the reasons in that blog are laughable.
 
Wow, this is insane. I have never really bothered getting a paid antivirus thing (Windows defender and Firefox + noscript have done me well) but this is legitimately frightening. Good thing I backed up everything important to me on a hdd a month ago.

I've had people tell me they had the scareware software on their computer, and It's kind of funny since it's not really legitimate, but this shit is the real deal.
 
For me is the other way around. Avast is too fucking nosy and intrusive. My combo is MSE + MB Pro. Plus other tools i use on demand.

Luckily Avast!'s more annoying features can be disabled, but yeah it's a shame MSE has fallen behind in actually catching stuff. It's one of the least intrusive antiviruses I've ever used.
 
i'm running with MSE as avast felt like early vista level nagware. it was supposed to be a decent option when i switched, am i behind on all this?
 
We were hit by this at work. It actually managed to encrypt a large portion of one of our more important network shares. Luckily it's very easy to track down the origin and remove it, but if we didn't have a good backup solution we would've been screwed.
 
But there's a genius who opened the attachment and spread the virus, right?

To be fair, one of the examples given in the reddit thread has a spoofed address from services@citibank, with the only hints to authenticity being the use of the receiver's email address ("Dear, crnaccravens" rather than "Dear John Smith"), some other aberrations in the body, and the attachment named as a .pdf with a pdf icon while it's actually an .exe.

It's certainly carelessness, but it's not exactly flagrant.
 
fuck, this is scary. I always try to be really careful when surfing the net, hopefully I don't catch this thing - because I'd be FUCKED. I don't live in the US and I've never even tried to mine a bitcoin in my life.
 
I'd say I'm pretty tech-savvy, but this is my rude awakening that I need to have some av software installed asap. Following the thread for the best recommendations.


I also host a shared dropbox folder with my grad class of 25. If one of them were to get this on their system, could it then spread to everyone else that syncs up with that particular folder?


Edit - Not that I have any disposable income at the moment, but I'd say this wouldn't be a bad time to invest in bitcoin....
 
I've been hit with ransomware on my laptop before. I managed to clean it out myself though. That wasn't fun. This looks more serious than the one I had though.
 
I use Antivir + Zone Alarm, I have Trojan Remover (paid) and Malware Bytes.
 
Shit is making me paranoid as fuck.

Don't be paranoid. It seems to be targeting network systems mainly. As long as you're using an up-to-date antivirus, keep your software up to date, being careful how you browse, and don't do silly stuff, you should be fine.

In theory yes, but we don't know for sure. You may wish to install avast and/or Malwarebytes Pro and recommend your students to use it too, if the option is available.

Yeah, this is way more serious than that. I can clean out the average ransonware no problem, but this is something one can't do anything about. You either have to reformat or restore from a backup. :(
 
Oh shit. Can this get through DLNA networks?

My computer currently hosts a media server. One other Windows system is (probably) aware of that media server (though the user isn't). If that system got infected what could happen (the user still uses vanilla IE for God sakes).

Yup. Malwarebytes works together with most AV software.

Even MSE?
 
All digital future is going to suck

What's good about this ( us moving further into the digital age) is that we will be forced to take things like this way more seriously. The United States alone is really behind in this. Hence the rather rapid growth of jobs in that sector.
 
Well I jumped from MSE to Avast. What's people's beef with Avast? There do seem to be a lot of features. Not sure which ones to turn off.

I know man, but damn some folks are evil. Thank god my family mostly go online with their phones or a tablet.
 
Finally, something that justifies my weekly hard drive reformats.

I've used Norton, McAfee, AVG, MSE and Avast. Avast is by far the best AV I've used.

I don't really get the beef either. It has enough options for you to finely tune each aspect of it.
 
Even MSE?

MSE + Malwarebytes was my preferred combo for quite some time. It's fine. Arguably would be fantastic even if Microsoft kept up on day one exploits.

Ignorance and paranoia do not help anyone. Take the proper security measures and you need not be worried at all.

Avast's default settings are annoying. No I don't need it to use sounds, nor do I need it to check for updates to programs for me, and I definitely don't need a spinning icon in the taskbar every time I load any program. Luckily, this can all be adjusted, so it's a non-issue.

Finally, something that justifies my weekly hard drive reformats.

I imagine you're not serious, but lol...
 
Yep, I've decided to create a Linux server and script backup/demount. So if something like this or more robust happens, I'll have a demounted HDD volume with my files.
 
How long until these things can infect via cute cat .gifs


I'm running a full malwarebytes scan, the quick scan only found 2 things that were harmless

This thing is one step away from being the 1918 flu of computer data.
 
Should I be worried? I mean, I've never had a virus compromise my computer, but this thing sounds scary.

I'm not worried about me but my parents, uggggggggh.

lol, just thought about my parents.

But all they do is watch YouTube and check email. I should probably call them and tell them not to open any more attachments.
 
Tangential, but right now I actually can't find much evidence of Java being installed on my computer at all. I can't remember the last time I've had to update it, or installing it on this system at all come to think of it.
 
Gotta keep that FRESH COMPUTER feeling going strong

Probably up to... 4 or 5 this month. I have problems.

Do you at least use symantec system recovery or clonezilla? Or are you seriously formatting and installing Windows that often.
 
On a side note, I find the subject of cyber security really fascinating. Almost went to school for it.

When I was younger I was crazy about everything cyber security.
How anti virus worked fascinated me as much as the malware itself, I was part of several beta testing programs (NOD32, Online Armor, Prevx, System Safety Monitor, Sandboxie>this was a novelty back then), and even got mentioned on the credits Kaspersky Internet Security 7 release by my username (the one I used then), I was a Kaspersky fanboy :), for which they gave me a two year license as gratitude.
I was part of the Castlecops community (now defunct) where I got access to some nasty zero day malware, I used to put to the test several security programs on an old rig I had, from HIPS (Host Intrusion Prevention Sytems), these are the only software that provide 100% true zero day protection if you know how to use them, firewalls, to sandboxes, I used to write reports about which software detected what and message the developers about it.
I reported about a thousand new malware to virus analysts, most of those sent emails still lie on my gmail account...
Also I used to crawl the net on some particularly shady places and forums back then, most of them don't exist anymore.
I learned that making 100% undetectable malware was quite simple, and that the future of software security had to rely on heuristic detection and/or emulation of malicious software in a closed environment (sandboxes and HIPS do this), as purely relying on a petty list of definitions was stupid, now most AV and Firewall software have an heuristics engine and a HIPS-like protection module.
Eventually I lost the interest and it stopped being a hobby for me, nowadays I just use Windows Defender and common sense and never my PC has been infected, at least unintentionally. :)
 
Well, I've been meaning to nab the Pro version of Malwarebytes for a while so I went ahead and did that.

Likely don't need it, but I've also been using the free version for forever and don't mind tossing them some coin.

Assuming it's not a solid state drive, you realize you are harming the life (however minor it may be) of your drive by doing this? :p
 
safe mode and malwarebytes.

Not sure what you mean. The malware encrypts your files, there's literally nothing anyone can do to reverse the process as the private (master) decryption key is held on remote servers until the ransom is paid.

SSDs can take something like 300k+ writes per bit. That's not the problem.

It's that installing Win7 from DVD is like 15 minutes, then all updates takes like 2 hours. because of .NET.

I said assuming it's not an SSDs, lol.

If he's really paranoid that much, he should invest in drive cloning software. >_>;
 
Dude...

If you're going to be paranoid, at least use disk imaging/cloning tools.
Ill look into them.

I had a feeling that I was, but I never looked up any information about it. I usually don't reformat this often in a month (only reached this many because I had some Windows 8 install issues and eventually went back to 7) but I do reformat entirely too often.
 
People that make crap like this can burn in a fire. I am very secure with my data. However, I know I will be making a trip to my parents to back up all their data.
