CryptoLocker Gang Earns $30 Million In Just 100 Days 202

DavidGilbert99 writes "A report from Dell Secureworks earlier this week reported that up to 250,000 systems have been infected with the pernicious ransomware known as CryptoLocker. Digging a little deeper, David Gilbert at IBTimes UK found that the average ransom being paid was $300, and than on a very conservative basis just 0.4% of people paid the ransom. What does this all add up to? $30 million for the gang controlling CryptoLocker — and this could be 'many times bigger.'"

      And so is the $30 million figure. 0.4% * 250,000 * $300 = $300,000.

        You can't expect journalists to have a grasp of basic math. Or the general public for that matter. Otherwise the headline "Company X settles 'largest lawsuit in history' at Y billion dollars" wouldn't have the impact it does after realizing Company X's revenue was Z trillion dollars. And who knows -- with the instability of bitcoin pricing, it might well be worth $30 million next week... -_-

    Does CryptoLocker actually do what it says when a person pays? That's better than a lot of commercial software I've used. The gaming, media, and high-level engineering software industries are particularly bad on this point.

    • We got hit by CryptoLocker twice back in November (in one case, it wreaked havoc on network shares because the user had way more permissions than necessary due to office politics). We didn't pay the ransom, but we worked with a vendor who was very familiar with CryptoLocker. According to them, every time people paid, they got the key as promised.

        We knew someone at a sister company that was infected with CryptoLocker. He had no backups (they have no IT infrastructure) so he paid the ransom to recover his files. It appeared to start decryption, but the machine was old and we had to let it run over the weekend to complete. Windows Security Essentials had to be disabled in order for the decryption to work, but it re-enabled itself and blocked the decryption. By the time Monday rolled around, the decryption sever had been shut down or his ransom window had expired and so he ended up losing his data anyway.

      I'm aware of several consulting clients who were hit by CryptoLocker to various degrees. Most restored their data from a previous backup. Two paid the ransom. Several waited too late to get us involved and were left without a backup and unable to pay the past due ransom.

    Just look at those guys: they don't need to take our freedoms with draconian DRMs and bought legislation. Their programs can be freely copied, in fact, their whole business model depends on the software being copied at no cost!

    What do they earn their money with, you ask? With high-quality cryptographic security service! Truly, a business model of the future.

    They are not blaming pesky pirates for their losses, they don't whine that someone uses their work without permission. They work harder, are creative and produce high-quality product. And that is their key to success!

      That's what makes it even sadder. True but oh so sad...

    • I would say this malware IS DRM. Because what it does is it encrypts the content, and then demands money to have it decrypted. Sounds very much like your average DRM scheme.

      A key difference appears to be that this one actually works - at least there is no mention in the article of it having been broken yet.

          DRM = Digital Rights Management. If I download videos or audiobooks with DRM, I have rights to use them, and the DRM controls these rights. My rights, not the rights of the movie or book company. So does this software. It controls _my_ rights to access the data. The only difference is that one makes sure I don't exceed my rights, while the other makes sure I can't execute my rights without paying ransom.

            Both DRM and cryptolocker encrypt your data with a key you don't know.

            The difference is that DRM attempts to let you use that key (to decrypt your data under the conditions that the DRM-imposer "allows") while simultaneously hiding the key from you (so that you can't decrypt your data under other conditions).

Now, that doesn't mean they have common sense -- plenty of people have all the sense of a turnip, but to suggest they put a car in the same category as a toaster is absurd.

      Unfortunately, an external drive backup using your scheme is of little to no use against this threat. It will encrypt all attached drives, network, USB or otherwise, so long as the user has permissions. It will start with commonly needed file extensions first.

      Unless your backup is not visible to the virus, you are toast. This is a situation where unattached, or off-site backups and cloud solutions win. A simple user with an always attached USB drive will still be toast.

      • Can it encrypt files on a different type of system? If you backup from a PC to a linux server, if the PC is infected can it corrupt the files on the linux machine. (sorry if this is an ignorant question)

        I generally have one addition layer of protection - the linux server has a backup that only has root write permissions, so the windows machines can't write to the backup disks (though I assume this can be hacked as well). Then I have offsite backups, but they are only updated monthly.

          File system and location matter not. If it is seen as a drive letter or sub folder in windows on the infected machine, and it has write/modify access, you are done.
        • For small business Linux storage servers, I personally use rsync to maintain a mirror of a Linux server's shared folder repository and copy out mirrored files that change to a rolling backup snapshot structure which is also shared out as read-only. If something encrypts all their documents, they have 60 days worth of backup snapshots and one of those will be massive from the huge number of files changing out when cron fires off rsync. Recovery is so simple, too.

        This may be archaic, but this is one application where tape backups can come in handy. Once data is stashed on a tape and the tape dismounted, it is out of reach to malware looking for anything online to disrupt. WORM tapes even more so, since once the session is closed, it is there for good, so malware can't erase the data that is previously written.

    Microsoft's brain-dead default of "hide file extensions" is cited in the article as part of the social engineering aspect that gets users to click on the files. It's the gift that keeps on giving... to black hats.

    Hiding the file extension does NOTHING to make things easier on the user or make the UI any cleaner. It's not like we have 40 column displays where the file extension is "too long" and going to take away "screen real estate".

    This has been going on literally for DECADES NOW. How can Microsoft be so blind? Whenever I get a new Windows box, it's the first thing I disable because if I don't, I'll just end up creating files with names like, "DailyLog.txt.txt".

    Whoever is at MS, insisting that this remain the default needs to be hauled out, shot, drawn, quartered, and the pieces sent to be displayed in the lobbies of their 4 largest offices.

    I believe I got hit by this about a week ago when I clicked on an advert linked on Chicago Tribune's website.

    A fullscreen message appeared saying my computer had been encrypted and I had to pay $300 to decrypt it. I pulled my network cable out and had to power off my PC because the keyboard would not work. I was able to boot back up, but when I logged in both regularly and in Safe-Mode, a full white screen saying "please connect to the Internet" appeared and I couldn't use the keyboard again.

    I pressed F8 on boot and booted into Safe-Mode Command line only. Once I logged in and saw the command line, I typed rstrui.exe (windows System Recovery) and using the Restore Wizard, restored to a checkpoint from a day earlier. I restarted my PC again and let it boot normally and once I was able to log in without seeing the message, reconnected my network cable.

    My PC was never encrypted. The message only said it was. The clincher was before I booted Windows in Safe-Mode, I used a Knoppix DVD to mount the Windows partition and copy off my personal data before I started the recovery process. The data was perfectly readable and not encrypted.
