First the good news: there are now free utilities for decrypting your data after a ransomware attack. Now the bad news: the tools only work for specific ransomware, not all variants. Cisco Systems' Talos team today released a free tool for victims of the TeslaCrypt ransomware attack that decrypts the locked-down files.
TeslaCrypt, which Cisco says may be related to the now mostly defunct CryptoLocker, uses symmetric AES encryption, which allowed Cisco to build a tool using the decryption key. Interestingly, TeslaCrypt warns that it uses strong asymmetric AES-2048 encryption to lock victims out of their files, but that's not the case. TeslaScript goes after various victims, including PC gamers, whose games and coveted and valuable Steam activation keys get locked down in its attack. 'We reverse engineered the way the TeslaCrypt worked and were able to develop the tool based on that,' says Earl Carter, threat researcher with Talos. 'In the past, we have also reverse engineered other ransomware, like Cryptowall, but in that case, the ransomware was using asymmetric encryption, so creating a tool was not possible.'
Hit by ransomware? Don’t pay the ransom! Our free ransomware decryption tools can help you get your files back right now. Free download! Tool decrypts, unlocks files hit by TeslaCrypt ransomware attacks. First the good news: there are now free utilities for decrypting your data after a ransomware. We worked collaboratively with another security vendor and global law enforcement to extract the decryption keys for the Shade ransomware.
Kaspersky Lab, meanwhile, offers a tool for victims of the CoinVault ransomware. Kaspersky, which teamed up with Dutch law enforcement authorities in the CoinVault attacks, obtained access to the private keys from the attackers and offers CoinVault victims who are locked out of their data access to their confiscated key. 'The Kaspersky instance is similar to the original CryptoLocker decryption tool that was developed after the police takedown of CryptoLocker. Both of those tools consists of a list of private keys obtained by law enforcement -- not necessarily all of the private keys generated by the ransomware. If one of these private keys corresponds to the key used to encrypt your system -- the keys are unique per system -- then you can recover your files,' Cisco's Carter says. Is different in that it can recover the files on any system infected by TeslaCrypt 'as long as the master key is still on the system and we developed the tool without having to access one of the threat actor's servers,' he says.
Dave Lewis, global security advocate for Akamai, says ransomware decryption tools are more of a stopgap measure. These ransomware decryption tools help, he says, but it's a temporary fix.
Lewis says he's noticed how ransomware attackers have gradually upped the ante in their blackmail. 'I've noticed it's been slightly going up incrementally,' says Lewis,. The key to defending against ransomware attacks are basic security hygiene: layered defenses and good security awareness programs for end users, according to Lewis. Cisco's Carter says the tool is aimed at all levels of victims, technical or nontechnical.
'This tool is only a single instance of ransomware. There are many variants of ransomware currently attacking user systems,' he notes. 'The best defense is a strong multi-layered defense strategy including an industry standard backup and restore policy. A good backup will circumvent almost all of these ransomware variants.'

Well I started using Impedio Security a while ago and I must say that I'm suprised I didn't find it earlier. It's great way to keep your data safe and don't have to worry about your files being corrupted iny any way. It's helpful because last time my friend acidentally deleted folder where I had important stuff for school and now I just put these folders in read-only volumes so no one can delete them, even malicious softwares. I was ransomware victim once but thank God now it's all over and I encouraged all of you to get Impedio and don't worry about malware anymore (y). Something about this reminds me of how the first skeleton key must have come about, followed by a long and distinguished array of lock pickers. Not only that, but the large keyring of both original and skeleton keys that we've come to associate with the locksmith who you call when you get locked out. More on that later.
First, I think this is a brilliant piece of work on the part of all parties who have provided decryption tools to victims. Not just because that is what they should do, but because it makes good business sense and it sets the tone for other companies and their customer relationships.and we're back. What I see here is an opportunity, too. Imagine developing a decryption tool that is the equivalent of that keyring your handy locksmith sports about. You'd keep it on a USB or similar device, and it would have hundreds of thousands of modules based upon reverse-engineered ransomware (or other sources of encryption) and their key stores.
It would be bootable and based on GNU/Linux, BSD or a similar UNIX flavor. No, you wouldn't be handing this out to folks, and no, only a 'locksmith' (or in this case an InfoSec professional) would carry it. There are similar USB-geared projects out there but there is so much more you could do with the architecture. Thinking out loud.
In this post (updated June 2015), we list our current top free tools for data encryption, including whole disk encryption, file level encryption, shredding, steganography, email, and network transport. After feedback, the list has actually grown to 28 free tools for data encryption, and if you have any other suggestions, we would be more than happy to try them out and include them in future updates. Whole disk encryption 1.
Is still my favorite in the whole disk encryption category, and is available for Windows users running the Pro and Enterprise versions of Windows 8. Pc Optimizer Pro Serial Keygen Download Crack. 1 or the Ultimate or Enterprise version of Windows 7. It’s also available in Server 2012 R2 and Windows 10, though which versions the latest desktop operating system will have it at release is yet to be seen. Bitlocker can encrypt full volumes using AES-256, and can leverage boot PINs, TPM modules, two-factor authentication, and so on, to secure access to the data on the volume. Bitlocker can be applied to the operating system volume, other volumes individually, or to all volumes on a machine, and can be managed enterprise-wide through GPO. Recovery keys can be stored in Active Directory, making this a very good choice for the enterprise that wants to ensure the company never loses access to encrypted data. And for those who are concerned that the government has a backdoor into Windows products,, and, and I think you should feel better about things. Now, that off-brand USB keyboard running that’s something to worry about!
Is an open source solution that can encrypt entire volumes using AES 256, Twofish, and Serpent. It can use AES, Twofish, or Serpent, taking advantage of AES offloading in newer CPU models, works with Linux and Windows, and can be used with external USB drives and optical media as well. Is Mac users’ answer to Bitlocker and is available in all currently supported versions of OS X. It uses 128 bit AES and requires you to set up a recovery key, just in case. Comes with Ubuntu Linux (and other distros based on Ubuntu) to provide full disk encryption, so those who prefer the Tux are able to get out of the box whole disk encryption in their operating system too.
It’s a selectable option during install and uses AES128 to secure your data. Shredding Because sometimes you want to give away or donate a drive, and you want to be sure there’s nothing on there that might come back to bite you later. Comes from Heidi Software in Ireland, and provides secure deletion of data from storage.
6., or DBAN to its friends, is a bootable image that can securely wipe drives from the boot up. It has a simple command-line interface with menu, but autonuke always works for me when hardware reaches end of lease. Note that DBAN cannot do SSDs, so take a look at File encryption 7. Is open source file encryption software that uses AES-256, can run on Windows, Linux, Macs, and even iOS and Android devices.
There are even Java and C# modules available for developers to integrate into their software. Can encrypt files and folders on local storage and is available at no charge for personal use, but also with enterprise class features including more options for key length, and the ability to encrypt remote data on network drives. It does not require administrator rights to use. Steganography 9. Runs on Linux, Windows, and OS X and can be used to securely hide data inside of other files. Steg’s best feature may be that you can evaluate the changes that will be made to the host file so you can determine if they will be obvious to anyone who views the file that something else is going on. Is another steganography tool that enables you to encrypt and hide files inside of other files.
Is a great program for securely encrypting and hiding files inside of other files. Email encryption 12. Offers a freeware version that users can use to both sign and encrypt email and attachments. Is a service, but a very useful one when you need to send an encrypted email and/or attachments.
There are both free and premium versions of the service available. Can be used for one-off needs, where all you have to do to send an encrypted mail is use your browser. The recipient needs a valid email address and the password to decrypt the message. Portable drive encryption 15.
Enables you to encrypt and password protect USB drives and local directories using AES-256 and includes portable versions of the software for when you won’t have administrative access. The free version can encrypt up to an 8GB partition, but you can purchase a license for larger disks. Is available for Windows users running the Pro and Enterprise versions of Windows 8.1 or the Ultimate or Enteprise version of Windows 7. This can encrypt portable media using AES-256, and can be managed using GPO. Is another portable media encryption tool that used AES-256 to secure all the data stored on USB drives and removable media.
One great feature about SecurStick is that you do not have to be an administrator on your workstation to use it. Another plus is that it works in Windows, Linux, and Mac operating systems.
The website is in German, but there is a link to a Google translation page right at the top. The program itself supports English, German, and Italian. Data in transit encryption 18. Offers SSL and TLS encryption for data in transit. Typically a Linux tool, for Windows and Solaris as well.
Can be used to provide an SSL transport for any TCP connection that does not support that itself. It is a free, open-source way to secure any TCP protocol. Remote management encryption 20. Is a secure command-line administrative service and client for administering Linux systems. It uses SSHD on the server and OpenSSH on the client to ensure a secure command-line session between systems. Is a secure command-line client for Windows (and other operating systems) that enables users to connect to SSH services securely.
Is the de facto remote management tool for Windows at the command line. It can use HTTPS to provide session-based encryption, but even connections over HTTP are encrypted using HTTP-Kerberos-session. Is a Windows tool from Microsoft that lets you manage multiple remote connections use RDP to your various Windows servers.
RDP connections use encryption and you can also securely store credentials to your servers in encrypted connection files so you can easily and securely remote into your systems. Multitaskers 24. Is normally considered a compression program, but what I consider the best compression program can also encrypt files using AES-256. It also integrates into the Windows Explorer menu, can compress-encrypt-email as an attachment in one click, and makes working with all formats of compressed files easy. This a good multipurpose tool with an often overlooked encryption angle. Is often just considered the free version of PGP, but it is oh so much more than just that. With command line tools, integration into dozens of other security products, and the ability to encrypt files, directories, volumes, emails, attachments, and to run on Windows, Linux, and Macs and to interoperate with the commercially successful PGP, it’s probably the de facto King of Encryption.
Can be used to encrypt files or directories and can also be used to send encrypted attachments to emails. You won’t find much on their website about this tool, but you can download it using the provided link.
Is a useful tool for providing file level encryption for cloud storage services like Dropbox, Box, OneDrive, etc. While its main focus is on protecting files stored in someone else’ cloud, it can also be used to encrypt files only stored locally, or stored to portable media, ensuring encryption of all your data.
From Axantum is a favorite for its ability to integrate into the Windows Explorer menu so you can right-click to encrypt a file, and also to send as an encrypted attachment to an email. Self-decrypting files can be created so the recipient of an email or USB key doesn’t need the software, only the correct password, in order to decrypt sensitive files. AxCrypt uses AES-128, with AES-256 being considered for a future release. Did we leave out one of your favorites? Leave a comment then and let us know!
Dave August 6, 2014 at 2:46 am Re:number 24. AxCrypt I cannot believe you included this program in your list of encryption software. To start with did you even download and install it before adding it to your list?
Because if you did, I’d suggest you scan your computer with Malwarebytes to remove files that are not removed by uninstaller. The bundled Adware, which is extremely intrusive and adds all sorts of third party files to a system isn’t the only problem. There are no prompts to exclude the Adware unlike what is written on the authors website, which is extremely misleading to the novice computer user. Casper Manes August 6, 2014 at 7:16 pm Readers, please take note of Dave’s comment above. YMMV, but better to be safe than sorry, so pay close attention to your download and install if you want to try AxCrypt. I cannot repro the issue Dave experienced, but that is not enough to be 100% sure all is well.
Hi Dave, I did download and install it. And there was a prompt for add-on software that, if you click ‘I do not accept,’ prevents the add-on software from being installed. The download link on Axcrypt’s site even calls that out below the downloads. “The downloads may include advertisement offers for additional software to finance further development of AxCrypt via the OpenCandy network, or via Softonic Universal Downloader. You may decline OpenCandy offers by selecting the ‘I do not accept’ radio buttton at the offer screen, and Softonic offers by unchecking the checkbox. You must still accept license agreement in the first dialog.
Please read more here. ” I just uninstalled, rebooted, and then reinstalled the software, was prompted as expected, declined, and then completed the install. Once I confirmed the software was working, I scanned my PC with Malwarebytes as you suggested.
It comes back clean. I’m really sorry you had a bad experience with an app that I have had good results with, but I cannot repro it. Thanks for letting us and other readers know. Tilgaz August 17, 2015 at 5:42 pm Dave seems to be a clicker. If you install Axcrypt and READ the instructions BEFORE clicking Continue you have the option to bypass everything. If you wind up with malware you installed it yourself. Also, agree with Kuzma, Cloudfogger is pretty well dead.
No updates or FB/Twitter posts since 2012, no response to tickets you submit, no email address and no phone number and a number of reported incompatibility issues reported. Searching the German white/yellow pages get you zero results. Express Tv Card E860 Driver Download here.
Kuzma Bruk November 18, 2014 at 7:58 pm Not sure why you mentioned CloudFogger as a favorite since it hasn’t been updated since 2012 and does not properly work with the listed cloud storage services due to API and OATH updates. Products like this seem to be superseded by newer more robust products like OneBigDrive. And for CF, TrueCrypt ceased development in May this year and posts the following on their website “WARNING: Using TrueCrypt is not secure as it may contain unfixed security issues”.
Just my 2 bits.
