What is SUMMON ransomware?

SUMMON ransomware – a cryptovirus developed for Bitcoin extortion

SUMMON ransomwareSUMMON ransomware - cryptovirus that demands Bitcoins from victims.

SUMMON ransomware is a file-locking virus that encrypts all personal victim data and generates ransom notes which demand to forward Bitcoins to the assailants for a decryption tool. Also, encrypted files are renamed in a complex manner. Original filenames are prepended with one of the attackers' email addresses summonunlock@gmail.com along with an appointed victim ID (both in brackets) and then appended with a .SUMMON extension.

If a victim had a file named a.pdf, it would now look like [SummonunLock@gmail.com][id=XXXXXXXX]a.pdf.SUMMON (Xs' stand for user ID). Two ransom notes appear when that's finished, one as a text file #ReadThis.TXT, and one as an HTML document, #ReadThis.HTA.

If you see any symptoms that your device might be infected with SUMMON ransomware virus, please don't panic and make rash decisions. It's not the end of the world. We have searched into the activity of the ransomware and other cybersecurity specialists' research shows that it is possible to remove the threat.

Ransomware has been lurking in the shadows of the internet for a long time now, and it won't stop spreading any time soon. There are ransomware families and rogue ransomware. It can target regular people as well as big corporations. New versions are developed daily. Here are a few examples of the latest ones:

All of them might use different encryption techniques,[1] distinct ransom notes, various appending methods, and extensions. Still, all of their goals are the same – frightening their victims into submitting to the assailants' demands. That's done by using various scare tactics in the ransom notes.

Here's what message developers of SUMMON ransomware send to their victims:

King Of Ransom
SUMMON Ran$omW4rE

Usually, a few files' free decryption is guaranteed to prove that a necessary decryption tool exists (including SUMMON ransomware virus). Sometimes a video of the decryptor in action is added. Victims are urged not to use any third-party software to unlock the files, as the only way to do that rests in the cybercriminals' hands.

SUMMON ransomware virusSUMMON ransomware is a threat that can be removed using professional anti-malware tools.

In many cases, that might be true, but agreeing with the assailants' demands is the worse thing any SUMMON ransomware victim can do. The send money motives the cybercriminals to expand their whole illegal operation and funds their research and development. The only way to stop ransomware from spreading is if victims stop paying the ransom.

Therefore, remove SUMMON ransomware from your devices. If you don't have the required tools, we recommend using either SpyHunter 5Combo Cleaner or Malwarebytes to automatically finish this task. Please remember to keep the virus databases of either of these apps updated, and they might prevent such mishaps in the future.

Ransomware-type viruses tend to mess with system files and settings, that could lead to various abnormal system behavior. So to finish SUMMON ransomware removal, users will have to use another tool. IT experts from Virusai.lt[2] recommend entrusting this task to the powerful ReimageIntego system repair tool.

Watch out for unsolicited attachments, and hyperlinks in emails

threat actors behind ransomware have many spreading options, including Remote Desktop Protocol attacks, deceptive ads, file-sharing platforms, and so on. Although, our research suggests that one of the most popular ransomware distribution options is spam emails.

Ransomware payload files can be hidden in either infected email attachments or hyperlinks. Cryptoviruses might be hidden as practically any file type, including .zip, .rar, .xlsm, .exe, .docx, .pdf, etc. As soon as either of the two options are clicked and opened, a virus might find its way onto the device and start encryption.

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
