What is Clop Ransomware?

Jakub Kroustek discovered Clop, a ransomware-like virus. This malware is programmed to encrypt data and rename files with the ". Clop" extension. It is a part of the wellknown Cryptomix ransomware family.

  • It uses the AES cipher to encrypt images, movies, music, databases, papers, and attachments.

  • The CLOP or ".CIOP" file extension stops victims from accessing their personal information.

  • Clop ransomware is regarded as extremely severe malware because it can infect most operating system versions, including Windows XP, Windows 7, Windows 8, Windows 8.1, and Windows 10.

  • Clop virus gets its name from the Russian word "klop," which means "bed bug" - a Cimex insect that feeds on human blood at night.

Clop ransomware is one of the most dangerous computer dangers because it creates entries in the Windows Registry. It can start or stop processes in a Windows domain, keeping it hidden from anti-virus software and users.

How Does Clop Ransomware Work?

It is commonly known that the Clop ransomware mostly targets organizations/institutions around the world rather than individual individuals, which could indicate that malware attackers are concentrating their efforts on corporations due to their cash potential.

Clop ransomware attackers have recently stolen and encrypted confidential data from multiple firms, including backups, financial records, thousands of emails, and coupons.

Clop ransomware has recently been linked to attackers using the CVE-2021-27101, CVE-2021-27102, CVE-2021-27103, and CVE-2021-27104 vulnerabilities in the Accellion File Transfer Appliance (FTA). Starting in February, these loopholes were exploited, resulting in the vulnerability of high-profile organizations. Additionally, there has been evidence of an affiliate stealing data from Accellion FTA devices via a webshell called DEWMODE.

Unfortunately, after some businesses failed to pay the ransom, the stolen information was made public on their dark web data leak site, 'CL0P – LEAKS.'

  • Clop ransomware is designed to change predetermined browser settings and perform a variety of functions in order to activate a built-in encryption section and corrupt all important files on your system, rendering them worthless.

  • When the victim tries to open the corrupted file, a ransom note appears, informing them of the encryption and providing instructions on how to pay the ransom, whether in Bitcoin or other cryptocurrencies.

Experts advise victims against paying the ransom, regardless of the amount demanded. According to studies, victims are utterly disregarded once ransomware hackers have received their money, with no way to restore their encrypted data.

The best way to avoid this is to plan ahead and purchase some backup. Maintain regular backups and store them on a remote server, such as the Cloud, or on unconnected storage devices, such as a flash drive or external hard drive.

How Can Clop Ransomware Infect My Device?

Clop ransomware can be spread by spam email attachments, trojans, URLs, cracks, unprotected Remote Desktop Protocol (RDP) connections, compromised websites, and other methods.

Much harmful malware can infect your computer via trash attachments and download links in the email body. Unsolicited emails from well-known organizations, such as banks and insurance companies, are common. Ransomware outbreaks are frequently spread through pornographic websites.

How can you avoid being infected with ransomware?

The key to computer security is to exercise caution. The main causes of computer infections are a lack of information and negligent activity. As a result, be cautious when using the internet and downloading, installing, and upgrading software. Before you open an attachment in an email, think twice.

Do not open anything if the file/link does not affect you and the sender's email address appears suspicious/unrecognizable. Furthermore, only use direct download links from official sources when downloading software. Because dangerous software frequently spreads through third-party downloaders/installers, these techniques should not be used. The same is true when it comes to software upgrades.

It is critical to maintaining installed apps (and operating systems) up to date; however, this should only be accomplished via the official developer's established features or tools.

For two reasons, you should never employ software cracking tools −

  • Using pirated software is considered a cybercrime because you are physically stealing from software providers, and

  • There is a substantial danger of infection because these tools are frequently used to spread malware.

Finally, install and run a reliable anti-virus/anti-spyware package, as these tools may detect and remove malware before it causes any harm. If Clop has already infected your machine, we recommend conducting a scan using Combo Cleaner Antivirus for Windows to remove the ransomware automatically.

Conclusion

Cybercriminals have figured out how to develop malware more adaptable, powerful, and dangerous than ever before. Clop ransomware, an invasive ransomware family that has infected companies all over the world, is one of this malware. SD Bot, which is used by TA505, should be informed of how it can contribute to the propagation of Clop ransomware.

We must act and enhance our cyber defensive systems, as well as be cautious when using the Internet and downloading, installing, and upgrading our software systems.
