YOUR_LAST_CHANCE ransomware removal instructions


YOUR_LAST_CHANCE is an updated variant of a high-risk ransomware called Nemesis. It was firstly discovered by a malware researcher who goes by the name of GrujaRS. As with its predecessor, YOUR_LAST_CHANCE encrypts most of stored files and renames them. This variant appends filenames with victim's unique ID and ".YOUR_LAST_CHANCE" extension (therefore, ransomware's name). I.e., encrypted "sample.jpg" would be renamed to something like "sample.jpg.id_3057868259_.YOUR_LAST_CHANCE". Additionally, YOUR_LAST_CHANCE automatically opens a temporary text file named "temp000000.txt", as well as generates another text file named "_RESTORE FILES_.txt" and drops a copy in every existing folder.

As a rule, created text file delivers a ransom-demanding message. It basically states that files are encrypted and that victims must purchase a decryption tool in order to restore them. It is unfortunately true that developers of YOUR_LAST_CHANCE are the only ones capable of restoring data. It is currently unknown whether YOUR_LAST_CHANCE uses symmetric or asymmetric cryptography. Nevertheless, it is sure that each victim gets a unique decryption tool which is necessary to restore data. Now the problem is that all keys are stored in a remote server controlled by cyber criminals. For this reason, these persons can easily blackmail victims by offering a paid recovery. The price for YOUR_LAST_CHANCE's decryption is currently unknown. Nevertheless, cyber criminals typically ask for $500-$1500 in Bitcoins, Monero, Dash, or another cryptocurrency. Now no matter how low or high the price is, it should never be paid. Ransomware developers are notorious for ignoring victims after they submit payments. Hence, paying is very likely to give no positive result and users simply get scammed. We highly recommend to ignore all encouragements to contact these persons and, especially, pay ransoms.

YOUR_LAST_CHANCE is virtually identical to dozens of other ransomware infections, such as Lokas, Boooam, CAGO, and many others. Notice that all of them are designed to encrypt data so that developers could make ransom demands. Users should also know that encryptions are often performed using algorithms that generate unique decryption keys (e.g., RSA, AES, and similar). Therefore, if the malware is flawlessly developed, restoring data manually (without developers interference) is impossible. Just keep in mind that locally stored backups will be compromised alongside with regular data. For this reason, we highly recommend to store them in a remote server or either an unplugged storage device or remove servers. There's also a chance that used server/storage device will be damaged. For this reason, having multiple backup copies stored in different locations is strongly advised.

How did ransomware infect my computer?

In most cases ransomware infections are distributed using fake software updaters and cracks, trojans, unofficial software download sources, and email spam campaigns. Fake updaters typically infect computers in two ways: by exploiting outdated software's bugs/flaws or simply downloading and installing malware rather than actual updates. Same goes for software cracks which infect computers instead of activating paid software for free. Trojans are basically malicious applications that stealthily infiltrate computers to cause so-called "chain infections" - to inject additional malware into the system. Cyber criminals use various third party download sources like freeware download websites, free file hosting sites, Peer-to-Peer (P2P) networks, and other to proliferate malware by simply presenting it as legitimate software. By doing so, crooks merely trick users to download and install malware manually, without knowing. Email spam campaigns are also used in a similar manner. Crooks send hundreds of thousands of emails that contain deceptive messages encouraging recipients to open malicious attachments (links/files), which are typically presented as important documents. In summary, the main reasons for computer infections are poor knowledge and reckless behavior.

How to protect yourself from ransomware infections?

First of all, users must realize that the key to computer safety is caution. For this reason, paying attention when browsing the Internet, as well as downloading/installing/updating software is paramount. All received email attachments should be handled with care. Attachments that are irrelevant and those received from suspicious/unrecognizable email addresses should never be opened. We recommend to download software only from official sources, preferably using direct download links. Always remember that third party downloaders/installers usually include rogue apps, which is why such tools should never be used. Proper software maintenance is also extremely important. Always keep installed applications/operating system up-to-date. To achieve this, however, use only implemented functions or tools provided by the official developer. Software piracy is considered a cyber crime and since most of cracking tools are fake, the risk of infections is very high. Therefore, you should never attempt to activate software using third party tools. Lastly, we highly recommend to always have a legitimate anti-virus software installed and running, because such programs will help you protect the system from malware, as they're capable of detecting and eliminating infections before the system is harmed. If your computer is already infected with YOUR_LAST_CHANCE, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining YOUR_LAST_CHANCE ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of YOUR_LAST_CHANCE are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by YOUR_LAST_CHANCE, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.
