How to remove Spora 2.0 ransomware virus

Spora 2.0 strikes with destructive power

The first signs of Spora 2.0 virus, the heir of Spora ransomware, were detected in February, 2017. At that time, it was still under development, so it only sparked speculations about the possible capacity of the threat. The authors of the virus left a hint about possible Spora 2.0 ransomware attacks, which will target “other devices,” which means that the virus will be developed for other operating systems (currently the virus targets Windows OS).  While the majority of viruses release first virus’ versions with a few bugs in it and improve them over time, the crooks manifested their mastery – Spora ransomware^[1] emerged as flawless^[2]. However, the fraudsters were not satisfied with their achievement. Updated version – Spora 2.0 – is now online. Nonetheless, how perilous this virus might look, there are still ways to counter it. Remove Spora 2.0 virus by launching FortectIntego or MalwarebytesMalwarebytes.

Brief overview of the initial Spora version

The entire Spora project is created precisely, and it is clear that virus’ authors thought about every single detail^[3]. What makes this virus stand out from other viruses and surpass even such successful viruses like Cerber or Locky is that it provides a very user-friendly interface. Spora malware is capable of encrypting victim’s files without having access to the Internet, and it does that precisely. There are no flaws in the encryption routine and in the entire virus’ code, and therefore malware analysts cannot help victims to restore their data for free. Although, lately, computer experts spotted that “The HoeflerText wasn’t found” ads are distributing this ransomware. EITest malicious script, planted in infected websites, transforms a web page into an unreadable collection of characters and numbers. Then, the message pops up stating that a specific Chrome Font Pack is outdated and needs to be renewed. When a user enables the extension, he downloads the most troublesome threat – ransomware. The main Spora infection method relies on malicious .ZIP archives which contain .HTA files^[4]. These files have double extensions, for instance, .doc.HTA. The real extension is hidden; therefore the victim notices the fake .doc extension only. These malicious files are distributed via email, and as soon as the victim executes the .HTA file, the malware roots into the computer system and encodes all data on it. The HTA file also launches a DOCX file and displays an error saying that the document cannot be opened. Spora then uses CMD to delete Volume Shadow Copies and disable Windows Startup Repair. Finally, it modifies BootStatusPolicy.

The virus then creates a ransom note called [Victim’s ID].HTML. Once executed, it will point the victim to an individual copy of spora.bz site, which is actually an impressive and very well-put-together website, which asks to synchronize the compromised PC with the website by uploading .KEY file that is saved on victim’s PC. The victim then can choose one of the provided services – Full restore, Immunity, Removal, and File Restore. This is the first case when we see a ransomware offering different paid services to the victims. The most interesting thing is that there is a chat box^[5] in spora.bz site, which is like a group chat between victims from around the world and the cyber criminals. Cyber criminals never agree to make discounts, but they do “help” the victims by disabling the deadlines and giving more time to pay the ransom.

The updated version continues relying on the “HoeflerText wasn’t found” campaign. Interestingly, that Spora 2.0 version does not append any file extensions to the affected files. Likewise, it puzzles users identifying the scale of the damage. Spora 2.0 malware spreads in the form of a trojan. Depending on the type of your anti-virus utility Ransom_Spora.R00XC0DD617, Ransom_Spora.R08NC0RD617, and Ransom_SPORA.F117D6. Interestingly, that the malware uses the technical information and accurately pinpoints the geographical location. Then, it generates a the ransom message with a unique identification: XXOOO-AAAAA-BBBBB-CCCCC-DDDDD.html where the first two letters indicate the country code^[6]. RSA-1024 algorithm is employed for encoding victims’ files. Specific RSAPrivKey2 is incorporated in the ransom message. In other words, it reduces data decryption duration if victims decide to transmit the payment. As we remind continuously, it might be futile to rely on cyber villains’ sense of conscience. Instead, proceed to Spora 2.0 removal.

Peculiar transmission technique of the malware

Unlike other ransomware threats, the distribution campaign of this specific file-encrypting threat certainly sparks interest. Such vile and insidious technique of disguising the malware in a fake Chrome Font pack may boost the rate of infected users. However, in general, the virtual community should inspect every new browser extension before enabling it. The surplus of them might instead slow down the browser’s efficiency rather than assist you in daily browsing activities. Since Spora 2.0 ransomware is still fortifying its position in the market, it might also shift to other distribution techniques. Spam emails remain of the most profitable methods spreading crypto-malware. Watch for spam emails with “tax report” and “invoice” attachments. Verify the user before reviewing the contents. Spora 2.0 hijack might be performed with the help of other exploit kits, such as RIG, in the future. That is why make sure you protect your device and data properly.

Eliminating Spora 2.0 malware

Dealing with ransomware is never a pleasant experience. What is more, Spora 2.0 removal might not be successful enough if you meddle with it manually. Since it entangles your PC system and initiates registry modifications, it is of utmost importance to eliminate it completely. Remove Spora 2.0 virus properly with the assistance of malware elimination utility. It must be updated as well to detect all files of the virtual menace. It is likely that this new derivate version of Spora might prevent you from getting rid of it. In that case, use the below-indicated instructions. Either rebooting the device into Safe Mode or System Restore should restore the access. Since the malware is still quite new, there is no Spora 2.0 Decrypter released. Virus experts still need to investigate it more in order to come up with effective decryption.
