Delivery Approaches of .srpx File Virus

Cyber threats like .srpx crypto virus can be spread with the help of various vicious techniques. In most of the cases, spam emails remain the preferred one as it allows a variety of ways to trick users into installing the ransomware on their PCs. On the one hand, hackers can create crafted messages posing as legitimate service providers, on the other hand, they can attach infected files or present corrupted web links. Any interaction with that elements causes an automatic download of ransomware payload. Once it is on the computer, it can either infect the system immediately or request permission for particular additional action. Another delivery technique that may be used is malvertising. It involves the injection of malicious advertisements into legitimate online advertising networks and web pages.

Infection Flow of .srpx File Virus a.k.a Serpent Ransomware

The .srpx file virus is a new strain of Serpent ransomware which previously renamed corrupted files with .serpent file extension. The infection is triggered by a single executable file called Serpent.exe. However, .srpx file virus creates additional malicious files on the system in order to complete the attack. Files associated with the ransomware may be situated in the following folders:

  • %Temp%
  • %Roaming%
  • %UserProfile%
  • %AppData%

It may hide the presence of some malicious files by injecting them into any currently running system process.

The threat is also likely to modify Windows registry keys and set its payload to start automatically each time the Windows OS is powered on. Creating new values in keys like Run and RunOnce may support the displaying of its ransom note. The ransom note files are dropped in two different file types but both contain the same text:

After the 7th day, it rises to 0.75 BTC which equals to $1762.

Encryption Process of Serpent Ransomware

The new variant of Serpent ransomware could be called .srpx file virus because of the file extension of the same name it appends to each encrypted file. As its predecessor .srpx file virus is believed to be configured to encrypt more than 150 file extensions:

→.2011, .2012, .2013, .2014, .2015, .2016, .2017, .3dm, .7zip, .accd, .accdb, .accde, .accdr, .accdt, .aepx, .agdl, .aiff, .aspx, .back, .backup, .backupdb, .bank, .blend, .btif, .cdr3, .cdr4, .cdr5, .cdr6, .cdrw, .cfdi, .clas, .class, .cntk, .config, .craw, .db-journal, .db_journal, .ddoc, .ddrw, .defx, .design, .djvu, .docb, .docm, .docx, .dotm, .dotx, .dtau, .efsl, .erbsql, .fcpa, .fcpr, .flac, .flvv, .gray, .grey, .groups, .html, .iban, .ibank, .idml, .incpas, .indb, .indd, .indl, .indt, .int?, .intu, .java, .jpeg, .jsda, .kdbx, .kpdx, .laccdb, .lay6, .m2ts, .m3u8, .mbsb, .meta, .mhtm, .mone, .moneywell, .mpeg, .ms11, .myox, .nvram, .pages, .pcif, .php5, .phtml, .plus_muhd, .potm, .potx, .ppam, .ppsm, .ppsx, .pptm, .pptx, .prel, .prpr, .psafe3, .pspimage, .ptdb, .qb20, .qbmb, .qbmd, .qcow, .qcow2, .qdfx, .qmtf, .quic, .qwmo, .resx, .s3db, .safe, .sas7bdat, .save, .seam, .sldm, .sldx, .sqli, .sqlite, .sqlitedb, .tax0, .tax1, .tax2, .text, .tiff, .tt10, .tt11, .tt12, .tt13, .tt14, .tt15, .tt20, .vbox, .vbpf, .vhdx, .vmdk, .vmsd, .vmxf, .wallet, .xhtm, .xlam, .xlsb, .xlsm, .xlsx, .xltm, .xltx, .ycbcra, .zipx

The encryption is performed via combination of two strong cipher algorithms AES-256 and RSA-2048 which makes the decryption process almost impossible. All corrupted files remain unusable until the unique decryption key is applied to Serpent Decrypter. They are all marked with the malicious file extension .srpx.
