Spora ransomware virus. How to remove? (Uninstall guide)

Traits that make Spora ransomware one of the most dangerous ransomware today

Spora virus is a destructive, file-encrypting cyber infection which has spread across the web in an astonishingly short period of time. This new “big player,” which has derived from CryLocker, does not only cause a headache for the virtual community but seeds riddles for virus researchers as well. So far, malware analysts call it “the most sophisticated ransomware of all time.” First discovered on January 10th, Spora ransomware appears to be a data-encrypting Trojan[1] which started communicating with its victims only in the Russian language. However, after several weeks of operation, it has started traveling the whole world wide web. It gets executed with the help of close.js file. JavaScript files are popular tools among hackers. Surprisingly, the malicious program uses an entirely different, and very complicated data encryption algorithm which seems to be immune. Apparently, the virus creates contents of .KEY file by creating RSA key, encrypting it with a newly generated AES key. In addition, it encrypts the AES key with a public key inserted into the virus’ executable file, and finally saves them to .KEY. Data encryption routine of this malware is slightly less complicated: they are encrypted using an AES key encrypted with RSA cipher (unfortunately, we cannot say so about Spora ransomware removal). Recently, the gearheads introduced a more insidious distribution campaign – “The HoeflerText font wasn’t found” ads. According to the analysis, the virus currently targets only 23 file extensions:

.backup, .xlsx, .docx, .rtf, .dwg, .cdr, .cd, .mdb, .1cd, .odt, .pdf, .psd, .dbf, .doc, .sqlite, .accdb, .jpg, .jpeg, .tiff, .zip, .rar, .7z, .xls.

Spora virus

Files that have these extensions are secured using a long encryption key (the public key); meanwhile, the private key is sent to criminals remote servers and is kept there until the victim agrees to pay a ransom. Instructions on how to transfer the payment are provided in the ransom note which is usually saved on the desktop. Typically, these instructions point the victim to a place that contains even more instructions – the official Spora ransom payment site. Surprisingly, authors of this ransomware demonstrate excellent programming skills in their payment websites. Besides, their user support has surprised even the most experienced security experts. The number of payment sites has been increasing rapidly and now you can find 10 sites that are used for collecting illegal ransoms, including spora[.]bz, spora[.]one, spora[.]hk, and others.

The payment site[2] differs from websites that typical ransomware viruses normally point to because it provides a variety of options for the victim – one can remove Spora virus for $20, restore files for $30 and even pay $50 for ostensible immunity to ransomware attacks. However, if the victim wants to get a full restore package, has to pay $79. Keep in mind that the virus might ask higher or lower ransoms from different victims. In fact, such wide range of options elevates the “freemium” model to a new level. You probably have already heard that the traditional ransomware, including Cerber ransomware, offer to decrypt one or couple of files just to prove the decryption tool exists, and it is on crooks’ secret server. This new virus, on the other hand, breaks the full ransom price into pieces, offering the victim to purchase separate services. Authors of the virus accept the payment in BitCoin currency[3] only. On January 16th, the payment website was improved, and a “Help” page was added. The site also has a public communication window, a table of transactions already made, and other little details that all make a very user-friendly interface[4]. No matter what, the malware is definitely not user-friendly as it wants to extort money[5] from the victim. In order to get the decryption key, victims are asked to pay the ransom and send the .KEY file to crooks via the payment site. If you have been hit by this virus, make sure you delete it immediately. It is highly advisable to use tools like Reimage or Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus for successful Spora removal.

Spora and its follow-up versions

Spora 2.0 ransomware virus. Soon after the original version of the virtual threat got unleashed, cyber villains introduced an updated variant of the malware. The authors of this virtual menace launched a more crafty campaign to multiply their global infection rate[6]. EITest malicious code would redirect users to the website infected with an exploit kit. Shortly afterward, the web page would turn into a mosaic of miscellaneous source codes. Consequently, the notification “The HoeflerText font wasn’t found” emerges. In order to solve this inconvenience, the crooks offer to enable a special Chrome Font Pack. However, what users would download is not some fishy browser extension but a real virtual menace – Spora 2.0. Interestingly, that the folder carrying infection are double-zipped. Now the crooks demand approximately 2000 USD in exchange for the files[7]. Despite the elaborate payment site, there are no reports whether the felons returned all files to their victims.

Ransomware spreads via spam and exploits HTA files to infiltrate computers

Spora ransomware is currently disseminated via malicious email campaigns filled with infectious HTA files. These hideous files have double extensions, for example, PDF.HTA and the real extension is hidden so that the victim would think that .DOC is the real extension. Let us remind you that HTA file is HTML executable file format, and so when the victim opens it, it downloads close.js JavaScript file to the system folder called %Temp%. Here, the infection activates itself by extracting an executable file and opening it. This executable file is the main file which is responsible for the data encryption procedure. At the same time, HTA file opens a DOCX file, which shows an error message that says file cannot be opened. While the victim stares at this suspicious error, the ransomware encrypts all files one the system.

Malspam is currently the main technique used to distribute Spora. In the beginning, when this threat was using Russian language only, misleading emails used such subject: Скан-копия _ 10 января 2017г. Составлено и подписано главным бухгалтером. Экспорт из 1С.a01e743_рdf.hta. (In English that would be: “The copy of scan _ 10 Jan 2017. Written and signed by the chief accountant”). However, now you should bear in mind that this ransomware keeps changing and it will definitely use different subject lines. Of course, different malware dissemination tricks, for instance, via exploit kits, Trojans, phishing websites and so on, can also be expected. We advise you to be very careful while browsing the Internet and assess unknown Internet sites with suspicion. If you do not want to be tricked into installing questionable software or malicious software updates, you better not install anything from the websites that you have never visited before.
