Clop Ransomware: Immediate Steps to Take & How to Recover Quickly
With rapid encryption and relentless extortion methods, Clop Ransomware targets companies big and small. Learn how this ransomware works, explore real-world attacks, and get expert support to restore your files and get back on track.
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.
Disables Backups
Actively seeks and deletes backups to prevent easy recovery after encryption.Exfiltration Before Encryption
Extracts sensitive data first to increase pressure during ransom negotiations.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.
What should I do when I realize my data is encrypted by Clop ransomware?
If you’ve fallen victim to ransomware, follow these crucial steps:
Request 24/7 Ransomware Recovery Help
Get expert guidance to assess, contain, and recover safely.
Isolate Infected Systems
Disconnect infected devices to stop the spread. Avoid self-recovery.
Preserve Evidence Immediately
Keep ransom notes & logs. Do not restart or modify anything.
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.
CASE OUTCOMES
Our outcomes with Clop ransomware are consistently good. Most gangs using Clop ransomware consistently provide working decryption tools. However, we keep a database of data on scammers to protect our clients.
COMMON ATTACK VECTORS
Phishing is the most common attack vector for Clop ransomware.

Frequently asked questions
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.
In most cases involving personal data, which applies to nearly every ransomware incident, reporting is legally required. In the EU, GDPR requires notification to the relevant data protection authority within 72 hours of becoming aware of a personal data breach. The UK ICO requires the same 72-hour window. In the US, HIPAA-covered entities have 60 days to notify affected individuals (and immediately for breaches affecting 500+ people). The clock starts from awareness of the incident, not from a full technical understanding.
In most jurisdictions, paying a ransom is not illegal in itself — but it can become illegal if the payment ends up going to a sanctioned entity or country (OFAC-designated groups in the US, EU sanctions lists, UK Treasury lists). Before any payment, sanctions screening is essential. BeforeCrypt handles this compliance layer as a standard part of every engagement.
Most established ransomware groups do provide working decryption tools when paid — the business model depends on their reputation for delivery. However, decryptors are often slow, incomplete, or corrupt a percentage of files during recovery. This is where working with a specialist matters: BeforeCrypt tracks the delivery reliability of specific groups, negotiates sample-file decryption as proof of capability where the group allows it, and plans realistic recovery timelines based on our own engagement history with each group.
Most modern ransomware groups follow through on publication threats — stolen data appears on the group's leak site, is often mirrored to Telegram and dark web forums, and may be sold to third parties. Recovery becomes limited to whatever you can rebuild from backups.
Backups protect against file loss but not against data theft. Most modern ransomware groups exfiltrate sensitive data BEFORE encryption and threaten to publish it regardless of your recovery capability. This is why leak-site publication and negotiation still matter even for organisations with clean, offline backups — and why "we can just restore from backup" rarely tells the full story.
In most jurisdictions, yes — reporting is a standard part of a ransomware incident and, in some cases, legally required. In the US, that means the FBI (via IC3 or a local field office) and CISA. In the EU, national CERT and cybercrime units. Reporting does not obligate you to any specific recovery path but does open access to threat intelligence and, occasionally, decryption tools recovered by law enforcement.
Yes. We’ve handled 1,700+ incidents across ransomware, BEC and data-leak extortion. We identify the variant, decide decrypt vs. clean verified restore, and guide a controlled return to operations. When needed, we support negotiation & compliance—always legally and with a clear audit trail.
Yes. We produce insurer-ready incident reports with a defensible timeline, scope, likely entry path, exfiltration assessment, actions taken, and chain-of-custody. We can join the adjuster call, map our findings to your carrier’s forms, and provide GDPR/NIS2 notifications where required. Final acceptance always depends on the policy and carrier, but our packages are designed to speed up approvals and reduce back-and-forth.
MSPs keep IT running; they’re not built for evidence handling and incident triage. Insurer panels optimize claims, not necessarily speed & clarity for your business. We work alongside both: kick off in ≤2h, run forensic triage with chain-of-custody, coordinate safe containment, and deliver executive- and insurer-ready findings—without taking your environment hostage.
Because it turns chaos into fast, safe recovery. We cut downtime and limit damage while preserving evidence. Within ≤48h you get a forensic triage pack (timeline, likely entry path, scope, decrypt-vs-clean-restore decision, go-live criteria) so leadership can act with confidence. Result: controlled, verified restart—not guesswork.
