What is Php ransomware?

Discovered by Jakub Kroustek, Php is a ransomware-type infection from Dharma malware family. After successful infiltration, Php encrypts most of stored files, thereby making them unusable. While encrypting, Php appends filenames with victim's unique ID, developers' email address, and ".php" extension (e.g., "sample.jpg" would be renamed to something like "sample.jpg.id-1E857D00.[back_me@foxmail.com].php"). Once the encryption is over, Php generates a text file ("RETURN FILES.txt") and drops it on victim's desktop. In addition, Php opens a pop-up window.

The "RETURN FILES.txt" text file contains a rather short message which merely states that files are encrypted and encourages victims to contact Php's developers. Pop-up window, on the other hand, provides way more details. It is said that files are encrypted using RSA-1024 encryption algorithm and that victims have to purchase a decryption key/tool in order to restore it. Unfortunately, the fact that cyber criminals are the only ones that can restore data is true. RSA is an asymmetric encryption algorithm which uses two keys - public (encryption) and private (decryption). Restoring files without the private key is impossible. For this reason, cyber criminals hide all keys in a remote server and offer victims to ransom their keys. The price isn't specified - all details are provided via email. However, research results show that cyber criminals typically ask for $500-$1500. The message only notes that ransom must be paid using Bitcoin cryptocurrency. Additionally, victims are allowed to attach one file (up to 1Mb, non-archived). The file will then be decrypted and sent back as a proof that decryption is actually possible and that these persons can be trusted. However, you should never trust these persons. Cyber criminals are notorious for ignoring victims, once payments are submitted. For this reason, paying usually gives no positive result and users merely scammed. Unluckily, Php is an undecryptable ransomware - there are no tools capable of cracking its RSA algorithm and restoring data for free. Hence, the only thing victims can do is restore everything from a backup, if there is one created.

Php decrypt instructions

There are dozens of ransomware infections that share many similarities in-between. The list of examples includes (but it is not limited to) Cezor, Isolated, Guesswho, and Basilisque Locker. Just like Php, listed examples also encrypt data so that developers could blackmail victims by offering a paid recovery. The problem is that most of these infections are performed using encryptions like RSA, AES, and other that generate unique decryption tools. Hence, if the virus is fully developed and has no bugs/flaws, restoring data manually (without developers interference) is impossible. We highly recommend to maintain regular data backups and store them in remote servers or unplugged storage devices (locally stored backups will be compromised together with regular data). Moreover, there's always a chance that used server/storage device will be damaged. Hence, it is advised to have multiple backup copies stored in different locations.

How did ransomware infect my computer?

Infections like Php are usually distributed using fake software cracks/updaters, trojans, unofficial software download sources, and email spam campaigns. Cracking tools are meant to activate paid software for free. Yet most of them are fake and they simply infect computers rather than providing access to paid features. Same goes for fake updaters which infect computers by exploiting outdated software's bugs/flaws or simply downloading and installing malware rather than actual updates. Trojans are designed to cause so-called "chain infections". They stealthily infiltrate computers with the intention to inject additional malware. Third party download sources like peer-to-peer (P2P) networks, freeware download websites, free file hosting sites, and similar are used to present malicious executables as legitimate software. By doing so, crooks merely trick users into downloading and installing malware rather than actual updates. Last but not least are email spam campaigns. Cyber criminals use them to send hundreds of thousands of deceptive emails that contain malicious attachments (links and/or files), as well as messages encouraging recipients to open these attachments. In many cases attachments are presented as invoices, bills, receipts, or other similar documents just to trick recipients into opening.

How to protect yourself from ransomware infections?

It is extremely important to pay close attention when browsing the Internet, as well as downloading/installing/updating software. Every single email attachment should be analyzed with care. Files/links received from suspicious/unrecognizable email addresses and those that are irrelevant/do not concern you should never be opened. Moreover, it is advised to download software only from official sources, preferably using direct download links. Keeping installed applications/operating system up-to-date is also extremely important. Yet this should be achieved by using implemented functions or tools provided by the official developer only. Every user should know that cracking installed applications is illegal (software piracy is a cyber crime). Moreover, the risk of infections is extremely high. For this reason, you should never attempt to do so. Moreover, having a reputable anti-virus/anti-spyware suite installed and running is also extremely important, because such tools usually detect and eliminate infections before they mange to harm the system. The main reasons for computer infections are poor knowledge and reckless behavior - the key to its safety is caution. If your computer is already infected with Php, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
