PyLock ransomware removal instructions

What is PyLock?

Discovered by GrujaRS, PyLock is a high-risk ransomware infection that stealthily infiltrates computers and encrypts most of stored data rendering it unusable. While compromising data, PyLock appends each filename with ".locked" extension (e.g., "sample.jpg" would be renamed to "sample.jpg.locked" and so on so forth). Once data is encrypted, users are presented with a pop-up window containing a ransom-demanding message.

The opened pop-up window delivers a message informing victims that data is encrypted using the AES-256 cryptography. For this reason, victims have to purchase a decryption key if they want to restore it. Unfortunately, the fact that decryption requires a unique key is true. AES is a symmetric encryption algorithm that uses the exact same key for both encryption and decryption algorithms. A unique key is generated individually for each victim. Yet the problem is that victims cannot access their keys as all of them are stored in a remote server controlled by PyLock's developers. For this reason, cyber criminals can easily blackmail victims by offering a paid recovery. According to the pop-up window, each key costs 5 Bitcoins, which is currently worth of approximately $51000. Now it is obvious that no one will pay such amount of money to get their photos, music, and other similar files back. Therefore, there are two possible reasons why the size of ransom is so huge: 1) cyber criminals are still testing this ransomware and the price will eventually change, or; 2) these persons are using source code that is old, since Bitcoin's price has risen significantly during last few years (e.g., in early 2016, a single Bitcoin was worth of around $400, while at this current moment the price is just above $10000). Nevertheless, no matter how low or high the price is, it should never be paid. Ransomware developers in general are notorious for ignoring victims once payments are submitted. For this reason, there's a high credibility that paying will give no positive result. You'll simply support cyber criminals' malicious business and get nothing in return. For this reason, all encouragements to submit payments should be ignored. Unluckily, PyLock is an undecryptable ransomware, meaning that there are no tools capable of cracking its encryption and restoring data for free. The only possible solution is to restore everything from a backup, if there is one created.

Internet is full of ransomware-type infections that share many similarities in-between. Erenahen, b00m, Kokoklock - these are only few examples from a long list. Notice that even though the developers are different, all of these infections behave virtually the same: they encrypt data and make ransom demands. There typically are only two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Unfortunately, most of encryptions are performed using AES, RSA, and other high-end cryptographies that generate unique decryption keys. Therefore, if data was encrypted by a flawlessly developed ransomware, restoring it without developers' interference is impossible. Ransomware presents a strong case for maintaining regular data backups. However, be sure to store them in a remote server (e.g., Cloud) or either unplugged storage device (e.g., flash drive, external hard drive, or similar). That's because locally stored backups will be compromised alongside with the regular data. In fact, you should have multiple backup copies stored in different locations, due to the fact that there's always a chance that used server/storage device will be damaged.

How did ransomware infect my computer?

The exact way developers proliferate PyLock is currently unknown. However, users should know that vast majority of ransomware infections are proliferated using third party software download sources (freeware download websites, free file hosting sites, Peer-to-Peer [P2P] networks, etc.), spam emails, trojans, and fake software updaters/cracks. Unofficial download sources are used to present malicious executables as legitimate software. By doing so, crooks trick users into manual download/installation of malware. Email spam campaigns are used to send hundreds of thousands of deceptive emails consisting of malicious attachments (links/files) and messages encouraging recipients to open them. In order to create the impression of legitimacy, crooks present attachments as various "important" documents, such as invoices, bills, receipts, and so forth. Next go trojans, which are basically malicious lightweight applications designed to infiltrate systems and inject them with additional malware. Fake updaters usually infect systems by exploiting outdated software's bugs/flaws or merely downloading and installing malware instead of the actual updates, while fake cracking tools simply inject malware rather than providing users with access to software's paid features.

How to protect yourself from ransomware infections?

Firstly, every user should know that the main reasons for computer infections are poor knowledge and reckless behavior. The key to its safety is caution and, therefore, paying attention when browsing the Internet, as well as downloading/installing/updating software is a must. Always be sure to handle all email attachments with care. Files/links received from suspicious/unrecognizable email addresses should never be opened. Same goes for attachments that are irrelevant and do not concern you. Moreover, be sure to download programs only from official sources and, if possible, use direct download links. Similar rules apply to software updates. Keeping installed applications up-to-date is extremely important. However, this should be achieved only through implemented functions or tools provided by the official developer. Third party downloaders, installers and updaters often include rogue applications, which is why such tools should never be used. Every user should know that cracking installed applications is illegal (software piracy is a cyber crime). Moreover, the risk of infections is extremely high, since most of these tools are fake. For this reason, using third party/illegal tools to activate installed apps should never be considered. Ultimately, be sure to always have a reputable Internet security suite installed and running, because it will detect and eliminate most of computer infections before any harm is done. If your computer is already infected with PyLock, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
