Writer: How My Mom Got Hacked
HughPickens.com writes Alina Simone writes in the NYT that her mother received a ransom note on the Tuesday before Thanksgiving.."Your files are encrypted," it announced. "To get the key to decrypt files you have to pay 500 USD." If she failed to pay within a week, the price would go up to $1,000. After that, her decryption key would be destroyed and any chance of accessing the 5,726 files on her PC — all of her data would be lost forever. "By the time my mom called to ask for my help, it was already Day 6 and the clock was ticking," writes Simone. "My father had already spent all week trying to convince her that losing six months of files wasn't the end of the world (she had last backed up her computer in May). It was pointless to argue with her. She had thought through all of her options; she wanted to pay." Simone found that it appears to be technologically impossible for anyone to decrypt your files once CryptoWall 2.0 has locked them and so she eventually helped her mother through the process of making a cash deposit to the Bitcoin "wallet" provided by her ransomers and she was able to decrypt her files. "From what we can tell, they almost always honor what they say because they want word to get around that they're trustworthy criminals who'll give you your files back," says Chester Wisniewski.
The peddlers of ransomware are clearly businesspeople who have skillfully tested the market with prices as low as $100 and as high as $800,000, which the city of Detroit refused to pay. They are appropriating all the tools of e-commerce and their operations are part of "a very mature, well-oiled capitalist machine" says Wisniewski. "I think they like the idea they don't have to pretend they're not criminals. By using the fact that they're criminals to scare you, it's just a lot easier on them."

You should have lied. You should have written that they just stole the $500. Now, see, everybody who gets hit by them and saw your article will also feel compelled to pay them.
Your Mom's system was wide open. Every hacker I know has been in there.
And yes, the first thing it does it does is purge all VSS (shadow copies) and encrypt data from local and mapped drives PRIOR to notifying you've been had. That malware is the only thing that stands between you and your now encrypted data. Purge the malware or slave the drive to another host, and you won't get your data base.
Let me put it to you this way. Crytowall is very well engineered ransomware. It doesn't fuck around.
Be sure to keep a set of backups not connected to your PC/Network using the Grandfather-father-son backup scheme. Rotate media according (weekly, monthly, and yearly).
Life is not for the lazy.
Context, man!
The "Don't blame the victim" notion comes in response to this kind of (boiled down) common claim:
"It was her fault that we exploited her! It was impossible for us to choose to not exploit her. We take no responsibility for our own actions!"
Which is the way psychopaths operate. They're always blameless or their actions are 100% forgivable in their eyes.
Her ignorance and subsequent choices were on her; she could have protected herself better, but the crime is not her fault and the perps should get zero slack because of it.
Take your average computer worm, add this profitable payload, and this makes the bad guys rich. How does this work? What exploit are they using to install the payload?
First she probably used WindowsXP which has dozens of unpatched vulnerabilities which will never be patched since it is EOL. XP has no concept of user priveldges outside of programs so all services run as admin for everything. Drivers too can run as hardware and it has no ASLR or ram scrambling to prevent overflow attacks or stack smashing.
Secibd flash with ads and java is how these infections get in. Websites these days have over 20 ads for each tab. Hack a not stellar non Google Ad network and put a flash ad with a buffer overflow. Boom page loads and you are 0wned.
Best AV advise today is to run Adware. Even IE has support for this now! It may screw small websites but these webmasters do not respect a users security at all PERIOD. I use Java for Android and Teamviewer so I disabled the browser plug in. I also use NortonDNS which will filter out bad domains too and it is free to setup for any pc or router.
Do these and you eliminate 90% of infections. Oh and of course I use a standard user account. I have that and an admin account which is occasionally annoying with UAC but this helps and puts in another layer of security as now the payload will need to bypass this.

This is exactly the sort of crime that the government should be able to solve, there are so many fingerprints left, double that with the bitcoins (which aren't actually anonymous).
Granted, the $500 itself might not be worth much attention, but over and over and it adds up to a lot.
Plus this is the sort of nonsense that your government is supposed to do something about. If not stopped now, the problem just grows.
These criminals do this because there is low risk of getting caught and if caught, the punishment isn't likely to be high.
If I were in charge, I'd task the NSA with catching them, then publicly execute them on TV. While some people will say, "oh, that is overkill and not fair", I'd say, "yea, but it sure will give these criminals pause in the future, won't it?"
Our company also got hacked. Management sent everyone home, restored from backups. Then we spent a bunch of time figuring out what files were modified in the last 36 hours, and redoing that work over. Note that the hackers target only certain file types, eg. .doc, and .pdf, but not .xls, so were talking mostly about documentation. Unfortunately, our PC's are now limping along because the virus scanner is running all the time now, and so chews up resources.
Our company is Windows-centric for everything except code development (which is Linux using a VM under Windows), and this is a clear example of why Linux is more secure than Windows. Not necessarily inherently, but because Windows desktops are the "mainstream". And hackers target the mainstream!
To wit, I switched to Windows for a year, but subsequently, every search I did to fix Windows problems required putting "Windows" in the search box. This inevitably led to ever more heinously cunning hacker/virus/spyware results which had to be waded through. Try as you might to avoid them, eventually one of them ends up getting you. It ends up being about as much fun as a potato-sack race through a mine-field.
The victim is to blame for ignorance; the criminals are to blame for maliciousness. There's enough blame for everyone.
But that's just a sentiment.
Once you're in their jaws, I suspect that your feelings may vary - and not as if any of us are going to reward her for towing the unified line
Actually, that's maybe the solution - you cough up your own cash to reward those that "say no to extortion" - It's not a massive leap, the majority of our governments already do this with our taxes already. Sure, it costs more in the long run (those SAS/SEAL raids where everybody ends up dead and poorer) - but it's nice to take a principled stand in the abstract (when your loved one isn't going to die as a hostage, nor as a soldier sent to rescue them).
The French - they mainly just seem to pay up, and walk away with their hostages unharmed.
Now I'm sure there may be some objections to this (I've got some myself) - but our governments seem to have managed to overlook their scruples and the urge to teach lessons when a few banks asked for a bit of cash (or we'd have all descended into anarchy, seemingly).
My point, I'm not sure. It's vaguely around the point that we don't 'pay when extorted' - and yet we all pretty much do. What's interesting is the type of extortion your government buckles and pays for.
I would really hate to have all my files encrypted and inaccessible. I'd probably just pay the $500 with much begrudge.
That being said, as soon as I would get the encryption key and get my files back, I would post everywhere that the hackers did NOT give me the key after I paid the $500.
It's kind of like game theory. If enough people do the same, then fewer people would actually pay up, or the price would drop lower, thus proving an advantage for the victims.
Posting in the damn NYT that the hackers are true to their word assures that they have credibility, and just torpedoes the strategy above. In the same way that it's valuable for them to get the word out that they are (kinda) honest, it would be valuable for the victims to get the word out that they are crooked. Being the marketing and pricing geniuses they seem to be, they would surely lower the price if they had bad publicity. So in the name of future victims, I would like to sarcastically thank you Alina for giving those fuckers ammo. They'll probably raise their price now.
next up is them rebating her some money back for their "Victim get a Victim" refferal program.
You could easily imagine something like this being the next step, having them say "We'll decrypt your files for $500, but if you send this attachment to ten friends you can decrypt for $250".
You could easily see that working really, really well... and creating a massive increase in infection.

I feel bad for the victims of these vile bastards, but at the same time I think that if that doesn't get them into the habit of regularly backing up their files, then NOTHING will. Also a good motivator to get the hell off Windows.
I'd rather pay $800 to a “criminal” than $5000 to a lawyer
False dilemma. In no meaningful way whatsoever is the money paid to these criminals an alternative to legal fees paid to a lawyer for a completely unrelated matter. Implying that the two payments are alternatives is idiotic.

Best advice is GET THE HELL OFF WINDOWS!! I have a thriving little business upgrading people who are still on XP over to either XUbuntu or Mint. I've gotten calls after an upgrade with the user saying "I got this weird error when I open this email", and it turned out that the user had an email with the Cryptolocker vector, and the odd error was the malware *trying* (and failing) to encrypt files on an ext4 filesystem... At this point in time, THAT aint happening....
THANK YOU, Edward Snowden!! Americans owe you a debt of gratitude (whether they know it or not..)
So, the only thing between Cryptolocker and your user's files was the FILESYSTEM? And you think the problem was the OS?
Seriously, this thing was actually running on your Linux distribution (as you yourself admit) and the only thing that saved you was that it wasn't (yet) adapted to the filesystem. So, pray tell, how is Linux the magical mystery sauce which saves the day?
Oh wait I forgot - you can't blame the victim ever no matter how much of a stupid fucking idiot they are!
I blame our industry for being as you put it "stupid fucking idiots". The most common attack vector for this particular malware and many like it is email attachments.
It's 2015 anyone in the world can still send an email with file attachments to anyone using whatever FROM address they'd like without any prior trust relationship, vetting or authorization by receiver. Most mail clients let users execute it in the same security context as the user without so much as a peep.
It isn't the users fault they don't fully understand the depths to which the technology they are using is completely broken and wholly unsuitable for purposes for which it is used by countless millions on a daily basis.
It is *our* fault for installing AV software and going back to picking our noses. *MILLIONS* of people are being exploited using the same attack vectors with malware and spyware... this business of calling everyone "fucking idiots" is getting old.
you say that as if the other major operating systems didn't have that feature for years
Come on, I am not saying that in any way. I'm saying that Time Machine is a system that really is so easy to enable that real, nontechnical people ACTUALLY USE IT, and that the features it has makes malware like this a non-starter.
Yes, all of us technical folk have been using various things to backup stuff forever. But Time Machine brings versioned backup to the everyday user (an important aspect of the protection is keeping older versions since a simpler mirroring backup means a users files could still easily all be lost on next backup that overwrites the mirror).
The reason why this is possible is again a combination of hardware and software - Time Machine as software alone is not nearly so powerful as it is combined with a unit that doubles as a WiFi router and backup disk, which is recognized as such by the system. Literally my mom can set it up and actually use it. I cannot imagine the countless disasters this has averted for people without technical family members to help them with issues.

That was true 4-6 years ago, but not today. Now we're seeing most of this stuff getting installed via zero-day exploits in browsers and plugins like Java and Flash, and distributed via third-party advertising networks. It's a lot harder to blame someone for getting compromised via a browser plugin they didn't even know they had.
The best protection these days is still to block all advertising, run with limited permissions, and have automated external backups with versioning. If the user is capable, blocking all third-party scripting is also incredibly effective.

You just listed some of the best features of email.

Now this is true. Antivirus software has been a joke for a decade.
"What do you despise? By this are you truly known." --Princess Irulan, Manual of Muad'Dib

Just wait 10-20 years and commercial quantum-computers will be common enough that the key can be re-created and the data recovered. So if you have been hit by "ransomware," clone the disk and put both copies in a closet somewhere. Every year or two, copy the disk again.
In 5-10 years police agencies will admit to having such technology and people who committed serious crimes since the "Five Eyes" started sucking down as much of the Internet as they can and who have successfully evaded detection due to strong encryption may find themselves getting that "knock on the door."
Criminals who are very high-profile targets (think: Terrorism, top drug lords, etc.), they national police agencies either already have the ability to go back and decrypt all past recorded traffic and previously-seized computers or they will have it within a year or two, assuming the encryption is the kind that is in common use today (e.g. https: or PGP-like encryption with reasonable, not super-long key lengths). As to whether the police will admit to having this capability before the decade is out is an open question. If they don't, they'll either have to delay arresting people or cook up some form of parallel construction to make their case.
By the way, watch your national governments - if they haven't done so already they will try to eliminate or greatly extend statutes of limitation for the kinds of crimes associated with encryption, starting with those that are most scary to the public such as anything related to terrorism, high-level drug trafficking, and human trafficking. Or, instead of trying to generally extend/eliminate the statute of limitations, they may change the law to suspend the clock when encryption is used, so the time it takes from the day the evidence is seized or sniffed to the day it is decrypted doesn't "count."

Everyone is stupid.
I'm stupid. You're stupid. We're all ignorant of something.
Malice gets 100% of the blame.
To use knowledge of something to abuse and transgress against another who does not, is a crime. The only crime. And all of the blame
Analogy: if you leave a $100 bill on your front porch, yeah, that's fucking stupid.
But someone has to go on property they have no permission to, and take something that is not there's. That's 100% of the blame. The moral person will not steal that $100 bill. In fact, they'll ring the doorbell and educate the stupid person, that they should be careful and not leave money on their front porch.
You don't punish stupid, you educate it. You punish malice.
Unfortunately, we punish stupidity too much in this world, our anger is always in full rage and pointed at the dumb. And we let the truly malicious off, because our hate goes towards the stupid, and in the meantime, the malicious gets away. Or we have no more anger left for them.
It's some sort of fundamental weakness with human nature, that we do this: punish the stupid and ignore the malicious. When we should be educating the stupid and punishing the malicious.
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
Turns out, when Microsoft tried this, they really annoyed a lot of their customers and took an awful lot of stick for it. Even from people who would consider themselves fairly technical. Users don't want you to put hoops between them and what they (think they) want to do.
Typical user scenario:
Clicks malware.exe email attachment.
Email client: Email attachments of this type this type are dangerous. Are you sure you want to run it?
*yes*
MSE/Windows defender: Virus detected. Quarantine file?
*nah... seems legit*
Windows: Filez from teh internetz can be dangerous. Continue?
*Yes. How dare you question me Bill Gates!?!*
UAC: File malware.exe from some dude on the internet wants admin access to your computer. Allow?
*Stop getting in my way stupid computer*
Windows: Install unsigned drivers? Guidance: Basically no unless your plugging in exotic or old hardware.
*Get the **** out of my way piece of *** I bet that *** Bill Gates thinks he knows better than me*
MSE/Windows defender: ***DEFCON1DEFCON1***
*whatevs. I need those novelty smileys and cool web search*
Malware: Mwhahahaha installs pop ups, steals bank details, encrypts files emails child pr0ns to the police etc. etc.
*Wah.... f***cking stupid Bill Gates your software's **** I hate Microsoft. Plus whenever I want to do something it asks me questions like I'm stupid and it knows better*
They hate the dialogues etc. and just click through them. Don't get me wrong I'm all for warning dialogues, but they exist already and they don't help a large proportion of "average users".
And, before some smartypants points it out, I know MS have since said that UAC was designed to annoy users to encourage developers to write apps that don't require admin privileges. A good warning system *should* be annoying though, and hopefully fairly infrequently triggered by innocent actions (as it is now that UAC has been around for a while and developers have fixed their apps (and MS have tweaked it a little)).
