Windows 10: TeslaCrypt ransomware now impossible to crack, researchers say

Ramsomware has become a large presence on the net. The Locky virus is another example of the new ransomware that has no way to circumvent the encryption. If you want to effectively defend against this, your best defense is to have a back up of your OS & files. Your Anti Virus might stop the ransomware, but there's also a chance it won't.

Windows has a built in program to make a system image. Or you can use another program of your choice. But not having a back up when this strikes means either loosing your files or paying up & hoping that you do receive the decryption key. Be smart & make a back up before it happens to your PC/Laptop.

Please note that for your back up to have the best protection, it should be kept on an external HDD that is not normally connected to the computer at all times. The newer variants of this ransomware will seek out any/all disks, back ups & corrupt them.

Files encrypted by TeslaCrypt (.aaa extension) ransomware

TeslaCrypt includes several known versions and extension variants...unfortunately
there is no way to decrypt the newer .aaa, .abc, .ccc variants
without Tesla's private key. Earlier variants stored the private key as data files on the local disk which enabled victims to decrypt their files with the locally stored private key. These newer variants no longer store any data files
on the local disk and information stored in the registry as binary data only contains public keys and each shared secret. The only other alternative is to save your data as is and wait for a possible breakthrough...meaning, what seems like an impossibility
at the moment (decryption of your data), there is always hope someday there may be a possible solution so save the encrypted data and wait until that time.

QUOTE from
TeslaCrypt 2.0 disguised as CryptoWall

"TeslaCrypt 2.0. This version is different from previous ones in that it uses a significantly improved encryption scheme, which means that it is currently impossible to decrypt files affected by TeslaCrypt. It also uses an HTML page instead
of a GUI. Incidentally, the HTML page was copied from another Trojan – Cryptowall."

QUOTE from
TeslaCrypt 2.0 ransomware: stronger and more dangerous

"First, they’ve adopted the sophisticated elliptic curve encryption algorithm from creators of the famous and very troublesome CTB-Locker ransomware. Secondly,
they’ve changed the method of key storaging: now they are

using the system registry instead of a file on disk. Thirdly, TeslaCrypt creators have stolen the web page which victims see after their files have been encrypted from another ransomware family, CryptoWall."

 

TeslaCrypt V2 ransomware infection

I'm not 100 % sure but I think you might be infected by TeslaCrypt.

Well I'm done telling people to backup their data. No matter what you say they are not going to do it. I just read a story on some news page about a German town that actually paid the ransom to unlock the data on their network because they had no backup *Roflmao2

 

Excellent post Dr. Borg. Now, if we could just get people to do the backups, *before* they get hit...instead of learning a hard lesson.

 

I read that too....I couldn't believe it. It was a hospital or some gov office. Unbelievable, that places like that don't take proper actions to guard/back up their data *Rolleyes

And no matter how long it takes to make an image, it's well worth the time it took.

Yepperz, that's the trick, getting them to do it BEFORE disaster strikes.

 

The new ransomware encrypts connected storage places like an external HDD as well as cloud backups.
Anyway, since ransomware is so easy to avoid, I do not even consider it as a threat, just as a scareware.

 

Only if you leave your External drive ON !!! Which you should not.....make your image backup to external drive, turn off....nothing can access that external drive then *Smile

 

Exactly. As I mentioned above, keep your backups on a drive that you only use for that purpose. Anytime it's not being used to make a back up, disconnect it.

BTW, something I've been noticing, it's getting harder to find a drive with an off/on switch. I have a couple that have that feature, but the last couple I found didn't have that option, they were on all the time. I fixed that on one of them by putting my own off/on switch in the middle of the power cord. I'll get to the other one soon enough. But still, kind of surprised they went that way. Of course the newer ones don't need an external power cord, they run straight off the USB connect.

 

Hi Borg, I just use my external "toaster" it is 3.0 USB, has its on power button, can take Spinner or SSD Here's a pic .

 

In fact it does not really take a lot of time. Ok, you have to setup the backup software once. But after that you just connect your backup drive(s), start the backup, go to bed and in the morning everything is done. There is absolutely no excuse for not backing up. Well at least apart from laziness, ignorance and plain stupidity *Wink

Today's backup programs even allow system backups while the pc is in use. I'm backing up my system right now and at the same I'm writing this post. It's really a piece of cake. Ransomware? It does scare me as much as I'm afraid of hell... not at all!

Did you mean to make "Free tools for making backups of your system. " a Link ?
Your 1st Post above

Thanks Rick

 

The link is working for me if this is what you are asking.

 

The link for those words is just below it,





Which does work as COMPUTIAC pointed out.

 

Unfortunately it does Not show up as a link for me
