In order to recover .php files, the victim need the decryption key! The decryption process is a challenging task without this private key. Apart from it, the developers ask for large amount of ransom to enable the decryption key. Hence, the victim users are left with no other choice than paying the ransom.

Distribution Technique

The seeds of a malware are carefully planted on questionable websites to frame the honey trap for the users! The moment a connection is established followed by a wrong click on the website, these dangerous codes come in the existence with a silent switch and without the knowledge of the users, and they spread in the system.

Apart from the malicious websites, Trojans are another deceptive method used to distribute php file virus. Trojans are destructive programs designed to cause ‘chain-infections’. They gradually attack your system with the intention to further installation of nasty software.

Once in, php ransomware shows the qualities of a true master of disguise! It has its own set of rules to ensure it presences on a connecting network as well! It could be a data transfer request, the contact list of email client or even your favourite social networking list, php file virus is fined tuned to evade security protocols and journey to their selective destinations.

The moment this variant of dharma malware family establishes its identity in an affected system, it hunts for popular extensions that majorly represent user specific information.

 

Threat Behavior

To show its unethical presence and set the fear in the mind of users, it encrypts the file content with strong algorithm and makes the content unreadable. It appends a unique extension – .php to the file names. For example – ‘sample.jpg’ would be renames to ‘sample.jpg.php’.

Alike its siblings, it uses a powerful cryptography algorithm to encrypt the data. RSA – 1024 encryption algorithm is used to fulfil the evil idea of the developers of php virus. Once, the files are successfully encrypted by php malware, it generates a unique decryption key on the remote server. Keep in mind, obtaining the key is not a piece of cake! However, it offers a solution to the victim users. It asks for hefty ransom from the users to decrypt their sensitive information. The ransom amount may vary from $500 – $1500. Of course, in the form of bitcoins! In addition, these cyber crooks allow you to attach one .php file of around 1MB, which they decrypt for free as a proof. It is the trick to get the trust of victim users. After the encryption of the files/ documents, the ransom note ‘RETURN FILES.txt’ will be created in the victim’s system.

Ransom Note

Many of the users fall in the trap set by this expert marksman and end up paying to the demands. Unfortunately, there is no guarantee to the cure offered and the information may never be restored in many cases.
