What is Sqpc ransomware?

Sqpc file-locking virus that belongs to the infamous STOP/Djvu ransomware family

Sqpc ransomwareSqpc ransomware belongs to the infamous Djvu gang, which locks files and demands for a ransom payment

Sqpc ransomware is yet a very fresh detection that started its activities at the beginning of May 2020. People on Reddit reported[1] a never-seen-before .sqpc file extension appended to non-system files stored on the affected machine. Although the analysis of this malware is still in progress, researches have already attributed it to the STOP/Djvu ransomware family as they are built on similar malicious code and have the template features of the mentioned crypto locker. Despite some minimal differences, such as .sqpc file extension and _readme.txt, the virus spreads via spam, locks files using AES encryption, and then demands to pay either $490 or $980 ransom depending on the reaction time.

Although there some of the Djvu ransomware variants can be decrypted with a free Emsisoft's decryption software[2], the versions including Sqpc cannot be decrypted, at least not yet. The versions released after August 2019 are only decryptable if an offline key was used.

Summary of the ransomware
Name Sqpc
Lineage The ransomware belongs to the infamous STOP/Djvu family
Classification File-encrypting malware/ransomware

Contacts helpmanager@mail.ch or restoremanager@firemail.cc
Distribution The criminals behind this malicious piece of malware are usually using social engineering techniques allowing them to spread it via spam. Alternatively, its payload may be launched via unprotected remote desktop tools, brute force attacks or launched as a secondary payload of a trojan
Decryption First of all, copy the encrypted files to a USB flash drive or alternative storage and then remove sqpc ransomware from the system. After that, you can try STOPdecrypter. If it uses offline keys, then there is a high chance that the software retrieves your files. Otherwise, file decryption is possible by paying the ransom, which is not recommended
Elimination Get rid of the ransomware using a professional anti-virus program. According to victims, the ransomware is usually detected alongside other cyber infections, including trojans, adware, malware, and spyware.
TIP Dangerous cyber infections not only seek to extort money from people but also affect their PCs by compromising system files and increasing vulnerability. To fix any system damage, use FortectIntego tool.

Sqpc virus belongs to the group of cyber infections that are extremely dangerous. Ransomware in its nature is programmed in a way to perform multiple activities to decrease the system's performance, increase its vulnerability, and induce its user into paying the ransom.

Schematically every cryptovirus works in a more or less similar manner. Sqpc ransomware unravels in stages. As soon as it gets to the system, it installs into Windows Startup and injected obfuscated entries into Windows Registry. After that, it downloads additional files known as 1.exe, 2.exe, 3.exe, and pdatewin.exe. The purpose of these files is diverse, i.e. while one is responsible for terminating security tools, the others modify host files, connect to the C2 server, and, in general, have to heat the engines for sqpc cipher.

The successful launch ends up in a complete file lock. The virus appends .sqpc suffix to each file positioned on the infected computer. The victim is also presented with a ransom note _readme.txt, which contains instructions for the victim explaining what has happened and how to pay the ransom. Criminals expect the victim to return to them within 72 hours. In this case, extortionists will charge the decryptor for $490, whereas later the price doubles and becomes $980.

However, the presence of the ransomware may not be manifested by encrypted files. As pointed out by a victim on Reddit, the first sign of a virus present on the system was suspicious IPlogger websites popping up on the screen randomly. Besides, the system turned slow and exhibited extremely high CPU consumption.

If any signs of a virus occur, do not postpone a full system scan with the anti-virus program. The longer you wait, the more damage the malicious software can cause. This ransomware typically affects poorly protected PCs and may find a backdoor to it because of already existing trojan or spyware infection. To remove Sqpc virus from the system, use a really professional anti-virus program, which features a high detection rate and powerful removal engine. We recommend using SpyHunter 5Combo Cleaner or Malwarebytes tools.

Sqpc ransom noteSqpc file-encrypting malware demands its victims to pay the ransom within 72 hours in Bitcoins

Paying the ransom is not the right solution. Lucky those who have data backups. In this case, there are no worries as all you have to do is to remove Sqpc ransomware while the system is rebooted in the Safe Mode and then retrieve your files from backups.

Another way to decrypt files encrypted by .SQPC file extension is to run a scan with STOPdecrypter by Emsisoft. This tool is free to use, so it's worth giving a try. It has already saved thousands of people from paying for the extortionists. Besides, there are several third-party data recovery tools that can be helpful.

Treat spam emails with carefulness to avoid ransomware attacks

As explained by security experts from novirus.en[3], this ransomware has more than one dissemination strategy. In general, all methods are extremely stealthy and designed in a way to make less IT-savvy people hook on the bite. The following ways to spread ransomware are the most common:

  • Spam email attachments. Criminals craft malspam campaigns, which are implemented with the help of bots. Tens of thousands of infected emails are sent to random (or sometimes targeted) email accounts with an expectation that some of the attachments will be opened. The messages are usually created in an accurate manner to look as reliable as possible. In the disguise of governmental institutions, courier companies, or organizations, criminals push potential victims to click on .zip, .exe, .pdf, or other attachments carrying ransomware payload.
  • Another medium for ransomware to spread is game cracks and keygens[4]. Such pirated software allows the community to play games for free by cracking license keys. However, illegal software is frequently bundled with ransomware payload, which is executed as soon as the crack is opened.
  • Phishing websites may spread ransomware via infected software updates. Landing on a hacked website may be extremely dangerous. In most of the cases, people get redirected to dangerous websites unintentionally by clicking on suspicious links positioned on pornographic websites. Another reason may be an infection of an aggressive browser hijacker.

Although there are methods that criminals may use, the above mentioned are the most frequently used. There is no one-method protection to avoid ransomware attacks. First of all, ensure a comprehensive system's security so that it won't have easily exploitable vulnerabilities. Besides, be very cautious when browsing the web and checking email attachments even if they come from a seemingly reliable sender.

Sqpc attackSqpc virus can gain administrative privileges and affect the system's performance severely The elimination process of Sqpc ransomware

SQPC ransowmare can result in huge losses of personal files and money. File encrypting malware does not filter its victims. It attacks poorly protected systems and makes them even more compromised. Windows registry, startup, processes, and other components can be seriously affected by turning Windows sluggish, unresponsive, and full of errors.

However, the biggest problem is the encrypted personal files. Extortionists seek the one thing – receive the payment. However, it's not advisable due to the disclosure of personal details and possible identity theft. Instead, it's advisable to remove Sqpc ransomware with SpyHunter 5Combo Cleaner, Malwarebytes, or another professional anti-virus program and then try alternative data recovery methods. As we have pointed out, there is an official STOPdecryptor, which is can decrypt some of the Djvu ransomware variants.

Last, but not least, do not forget to restore the system's performance. Windows registries and other components can be recovered with the help of FortectIntego tool.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
