How do I know if BlackCat Ransomware has infected my system?

BlackCat Ransomware are Trojans that encrypt your entire network or specific machines of value. Upon notice of an attack, you are then given instructions of paying a specific amount in ransom to decrypt your files. BlackCat has been called “2021’s most sophisticated ransomware”.

First identified circa Dezmeber, 2021, the gang behind this virus is allegedly the ALPHV group, which deploys Ransomware-as-service model to distribute exploit kits, attack unprotected RDP servers, and install backdoor payloads. According to current intelligence, this is a rebranding of the ransomware group BlackMatter, which has ceased operations due to intense pressure from law enforcement.

BlackCat ransomware statistics & facts

RANSOM AMOUNTS

Compared to other ransomware variants, the ransom amounts demanded by BlackCat attackers can vary largely. The cyber criminals use a dark web browser known as TOR to automate their operations and manage affiliates.

But that doesn’t mean that these hackers do not have the gumption to demand a hefty extortion amount based on organizational size. The average BlackCat ransom amount is somewhere between $15,500–$120,000, with some victims reporting demands well into the millions of dollars. But it isn’t limited to the ransom demand.

Victims are faced with unexpected costs in buying and transferring bitcoins, mostly the 10% exchange fees applying to the quick buy methods of Paypal and/or Credit Cards. Along with potential threats to have their personal and business information leaked or sold on the internet if demands are not met.

AVERAGE RANSOM, USD $

AVERAGE LENGTH

The BlackCat ransomware downtime is a relatively shorter than normal ransomware attacks, since most attackers use automated TOR sites for accepting payments and expediting the process.

Depending on your company size and how often you use IT-systems in your daily business, this is the most expensive part of this incident. Additional to the unavailability of your IT-systems, this is damaging your company reputation.

You need to get your systems back up and hit the ground running as soon as possible. We’ll ensure minimum downtime once you let experts like BeforeCrypt to manage your situation and recover data.

CASE OUTCOMES

There is a high chance to get a working BlackCat decryptor after paying the attackers. This is because they use an automated process to accept payments and deliver the decryption tool. But there’s never a guarantee to get a working decryption key at all.

Most of the victims have reported getting a decryption key successfully on getting their data in original form.

COMMON ATTACK VECTORS

Security vulnerabilities, unsecured Remote Desktop Protocols and spear phishing emails. These are the primary reasons of how BlackCat infects and encrypts your system.

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.

Do I have to report a ransomware attack to regulators, and when?

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.

Is it legal to pay a ransom?

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.

Will paying the ransom actually get my files back?

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.

What happens if we don't pay the ransom?

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.

Are our files still at risk if we have working 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.

Should we contact law enforcement after a ransomware attack?

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.

Do you have deep experience with ransomware incidents?

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.

Will insurers accept your findings and reports?

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.

How is this different from my MSP or the insurer’s hotline?

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.

Why Should I Use A Cyber Incident Service?

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.
