BitDefender Free Ransomware Decryption Tool

81
Found 2nd Mar
Just noticed this tool, very useful for anyone caught by the ‘GrabdCrab’ ransomware and lost access to files.

Please note, this does not remove the ransomware, it simply decrypts your files, you should still take the usual measures to remove the threat.

Useful but the best defence against ransomware (ALL ransomware) is to take regular backups, and detach your backup drive between backups. I recommend the free version of EaseUS ToDo Backup for most people. It may be worth paying for the full version if they offer you a good deal - it has a number of benefits including emails to advise of backup status. ToDo will image your drives as well as take data backups I much prefer it to Acronis True Image which I used for many years although do wish it could be told to take a full backup every nn increments automatically, as True Image can.

Proof of concept is not the same thing as in the wild...This is …Proof of concept is not the same thing as in the wild...This is HotUKdeals, however the track record for the MacOS should be evidence enough of what a proper OS can do to mitigate attacks.I still have factory sealed copies of MacOS X & 10.4, the test is with 2 identical laptops - I install MacOS on one (I use the raw OS - I don't bother with any updates or drivers) and the latest Windows 10 build on the other, connect both to the internet. Guess what the MacOS doesn't get sniffed, the Windows 10 machine -even with the latest updates- gets hit every time!The way system files are accessed on a Mac or any *nix flavour is what keeps them more secure than the Windows platform.Windows 7 has several "hidden" OSes within it. For compatibility it runs a version of XP, it still uses DOS, there's Powershell in there and Media centre - so that adds 5 attack surfaces. Windows 10 has backward compatibility as well along with DOS & Powershell, so it too has many attack surfaces. *nix OSes by contrast only have 1 attack surface.As I have stated this is HotUKdeals so I'll bother going in to any further detail...


The reason Mac OS has a better track record is not because it’s any better at defending against threats. The main reason for this is Mac OS users equate to around only 9% of the market, compared to Windows at around 88%.

Why an earth would anyone put any effort into designing a threat which only targets 9% when they could put the same amount of effort into targeting 88%?

Only GrandCrab, but it’s a start.
Do you download it now or if you get hit?

You download it if you’ve been hit by the Ransomware and it will allow you to retrieve your files, something which was not previously possible without paying the ransom.

Interesting.
For more tools go here: nomoreransom.org/en/…tml
"The “No More Ransom” website is an initiative by the National High Tech Crime Unit of the Netherlands’ police, Europol’s European Cybercrime Centre and two cyber security companies – Kaspersky Lab and McAfee – with the goal to help victims of ransomware retrieve their encrypted data without having to pay the criminals."
Worth a try if you've been infected. However there are many ransomware variants. The main methods of infection are opening attachments/links in emails and visiting compromised websites. One way to open infected emails/websites without getting infected is to open them sandboxed, this way the real system remains untouched.I use a program called sandboxie, which has a free version. Prevention is better than cure Sandboxie
Here is a demo video, about 3 years old now, the thing about Sandboxie is while malware gets more sophisticated the containment element remains solid Sandboxie v ransomware

not that i know for a fact but doesn't the ransomware actuall prevent you from using the computer, beyond the flashing ransom notice and a phone number (homelands - new series ep2)? how on earth would you download it if you can't use your machine?
also, the conspriacy theorist in me can't help but think this would be the perfect way to infect with ransomware... hahaaaaa!

oh... erm...

With regards to storage location of backup, Would a separate partition on the same disk suffice or does it need to be a separate hard disk all together?
Is there any chance that the backup drive would also get infected?
Separate partition would be no better, a separate drive that is disconnected would be ideal. And DONT re-connect the drive till the main computer is free of detritus/virus/malware/ransomware. You only value a backup when you really really need it.

It depends on the type of Ransomware, you’re right some do, but this particular variant only encrypts files/folders rather than the entire OS or drive.

I’ve had some fun with sandbox’s in the past, interesting to see how some threats spread and watch what they do in a confined environment.

Agreed, someone give that man a medal..!

Regular backups are key, they protect your files from so much more than Ransomware too, system crashes, hardware faults, accidental deletion, theft of the device... you name it.. the list goes on!

So nothing to do with usage share of operating systems? macOS makes up a tiny minority of web clients, therefore far less likely to be attacked.

Because Apple’s overwhelming success has created a swathe of jealous saddos who hate them. Secondly, hackers love a challenge. Thirdly, many Apple users are personal rather than corporate targets, so won’t have heavy duty security policies.

OSX should be a soft target, but it really isn’t.
Would you not be better creating a user account for day to day Internet ect. If you get trouble that user account will be locked but the other account like administrator will be fine. Get your files off and nuke and pave drive. You have to trust all these 3rd party software don't have vulnerabilities or backdoors. Backup. Run security updates. Use common sense. I'm not convinced installing these types of protection software do anything of benefit except empty your wallet

I can't believe what I am reading! This is the biggest pile of crap I have read on this site! Windows 10 does not add extra layers or hidden OSes. It runs on an NT Kernel as does Windows 7. The NT kernel is the engine of the Operating System and there is only one kernel per Windows OS. There are no hidden OSes - good grief! The attack occurs because the malware file has made itself on the computer and executed. Once on the computer, the files are accessible and it doesn't matter if the computer is Windows based or Mac based - the files are accessible when the malware has executed with the correct access rights. A user who executes malevolent attachments would have their system attacked on a computer of any OS - don't tell me that it is safe to open email attachments on a Mac!

What did you mean "the MacOS doesn't get sniffed"? You can't sniff the OS! It's network traffic that can be sniffed and any computer's network traffic can be sniffed. In actual fact, many businesses use hardware firewall, DMZ and other forms of network protection against malware. If the malware has breached the network security and made its way onto a Windows or a Mac computer, then the issue is a potential vulnerability in network security.

The reason why malware affects Windows machines more than Linux, Mac and others is due to the vastly higher amounts of Windows machines in operation compared to others. The comments about Macs being invulnerable to malware is very much akin to "The BBC Micro or Sinclair Spectrum don't seem to be affected".

MacOS is just as vulnerable as Windows. The amount of vulnerabilities has risen over the years for MacOS, look at the CVE website here:

cvedetails.com/pro…=49

There is no hidden OS, but i can see why people may make the mistake of thinking Powershell is another operating system. To keep it simple, its a scripting language based off the .NET framework.

Ransomware is very common nowadays, most ransomware makes it into systems because people

- are Unware of malicious attachments in emails.IE PDF's, Office docs with macros.
- Dont set strong enough passwords.
- Dont patch their systems regularly.

I agree that most businesses use firewalls.. but thats only for stateful traffic. The technology used in most now are UTM's such as Palo alto. Host intrusion detection systems are somewhat effective too, like Carbon black or Cylance.

I wouldnt buy this product at all.

Like I said this is HotUKdeals - you obviously have never run anything in compatibility mode - guess how Microsoft achieve that?
I started with the comment proof of concept is not the same as in the wild.
Stop spouting nonsense and try the experiment yourself...
"The reason why malware affects Windows machines more than Linux, Mac and others is due to the vastly higher amounts of Windows machines in operation compared to others" - what so that's safety by obscurity? That is just nonsense - you could argue that virii were invented on the Mac, the first were inert - and spawned a game called bunny killer...
There are hidden OSes on Windows - what do you think DOS is? What do you think Powershell is?
You know when you boot into recovery mode that's not Windows, that actually DOS...
Come back when you read up and have some knowledge to back up your statements...
