How do I know if Clop ransomware has infected my system?

If you are unable to access your files, and see a notice on your desktop that your files are encrypted and demanding payment, you may be infected with Clop ransomware.

Clop ransomware started to appear in phishing emails some time in 2019. When it encrypts files, it usually changes the name of the files by adding a .clop extension. Clop uses RSA encryption standard, and we know of no functional free decryptor tools for Clop.

More recently Clop ransomware has been known to shift to data exfiltration only and not encrypt systems.

Why You Shouldn’t Attempt to Fix It Alone

If Clop ransomware has hit your business, taking the wrong steps can cause permanent data
loss or legal risks. Like a crime scene, a ransomware attack must be preserved—tampering
with encrypted files, attempting self-recovery, or engaging with attackers can destroy
critical evidence and reduce your chances of recovery.

The right response in the first moments after a Clop attack can make the difference
between full recovery and permanent data loss. Follow these critical steps to protect your
data and maximize your chances of restoring operations.

CLOP RANSOMWARE FACTS & FIGURES

RANSOM AMOUNTS

Clop started out with relatively small average ransom amounts, but the gangs using Clop have now moved towards targeting larger organizations. As such, the average ransom amount has increased.

The average Clop ransom amount is currently around $40,000. Clop gangs demand payment almost exclusively in Bitcoin. It’s better not to pay the ransom, as this encourages the hackers, but if you are in a situation where that it your only option, keep in mind that quick-buy methods of purchasing Bitcoin like PayPal or credit card carry an additional fee of up to 10% and sometimes require verifications which can take days. We keep a reserve cryptocurrency on hand for instant payment with no additional purchase fees.

AVERAGE LENGTH

Downtime resulting from Clop ransomware is often longer than with normal ransomware attacks. The manual process of communicating with the attackers can further delay response time.

For many organizations, downtime is the most expensive part of a ransomware incident. Another negative side effect of a data breach can be damage to your reputation.

Your goal should be to get your systems back to a productive state as soon as possible. The best way to do this is to call in experts who know the ins and outs of Clop ransomware to complete the removal and restoration process immediately.

Frequently asked questions

How Does Ransomware Encrypt Files?

Ransomware encrypts files using advanced cryptographic algorithms, typically AES (Advanced Encryption Standard) or RSA (Rivest-Shamir-Adleman). Once executed, the malware scans the system for specific file types and encrypts them, making them inaccessible to the user. Some variants use symmetric encryption (AES), while others combine it with asymmetric encryption (RSA) to lock files with a unique key pair.

Can You Decrypt My Ransomware Encrypted Files?

Decryption depends on the ransomware variant. In some cases, publicly available decryption tools exist, but not all attacks have a known solution. You can submit a free ransomware recovery request, and we will check for possible decryption methods.
