New Philadelphia Ransomware – More Information
As soon as the new variant of Philadelphia has infected a computer, it may immediately drop it’s files under different names in one of the commonly targeted Windows folders by malware where it can act in a privileged and obfuscated mode:
After the files are dropped on the user PC, the Philadelphia virus may begin to modify it’s settings. To begin with, the virus may target the Windows Update registry key to run a successful encryption via the update process:
→HKCU\Software\Microsoft\Windows\CurrentVersion\Run\Windows Update
After having done this, the Philadelphia malware may also immediately begin to encrypt files. Similar to the first version of Philadelphia, this one may target some or all and more of the following file extensions:
.7z;.asp;.avi;.bmp;.cad;.cdr;.doc;.docm;.docx;.gif;.html;.jpeg;.jpg;.mdb;.mov;.mp3;.mp4;.pdf;.php;.ppt;.pptx;.rar;.rtf;.sql;.str;.tiff;.txt;.wallet;.wma;.wmv;.xls;.xlsx;.zip
For encryption, Philadelphia may employ a cipher that generates a decryption key which is sent to the cyber-criminals’ server. The server may be located somewhere in South America, since the previous version of Philadelphia targeted primarily Brazillian users.
Files that were encrypted by the Philadelphia virus may or may not have their names changed and may appear as the following:
The affected users are convinced that their only way out is if they follow the ransom instructions of Philadelphia ransomware:
→“All your documents (databases, texts, images, videos, musics, source code, etc.) have been encrypted.
What can I do?

How?
You can use LocalBitcoins.com to buy bitcoins, or any other preferred method.
