What is Conti Ransomware and how does it infect my files?

RYUK, first discovered in August of 2018, has already wreaked havoc for multiple large corporations and medium companies. Conti surfaced in July 2020 with behavior and ransom notes eerily similar to RYUK, such as AES 256 bit military grade encryption combined with RSA 4096.

Similar to Ryuk, Conti ransomware is particularly threatening for corporations and organizations that operate large and complex network infrastructure. While it has similarities to Ryuk’s source code and modus operandi, Conti is smarter, quicker and faster in encrypting data while shutting down entire networks. The connection between Ryuk and Conti is further supported by the fact that Conti attacks are increasing as Ryuk attacks decline.

The AES 256/RSA 4096 encryption alongside 32 simultaneous encryption threads used to encrypt files at unsurpassed speeds is what makes this an extremely dangerous malware for medium to large sized organizations. This means that the Conti ransomware can encrypt an entire network much faster than most other existing strains of ransomware, making it more difficult to catch and stop before it disrupts operations.

CONTI ransomware statistics & facts

RANSOM AMOUNTS

Conti targets corporations and enterprises with a large IT infrastructure. As such, ransom payments are often much higher than other variants, often in line with Ryuk.

The average Conti ransom amount is somewhere between $100,000–$350,000. However, some attackers have even demanded as high as $800,000 to over $1 Million. When purchasing Bitcoin to pay a ransom, quick-buy methods include a fee of as much as 10%.

AVERAGE RANSOM, USD $

AVERAGE LENGTH

Since Conti attacks corporations, the average length of incident is longer than other ransomware. This is because of the manual communication with attackers through email, which adds a considerable delay in the response time and data recovery process.

Since this is an enterprise-level attack, the longer your systems and files are held hostage, the costlier it will be in terms of PR damage. Your goal should be to get your systems back to productive state as soon as possible. The best way to do this is to call in experts like BeforeCrypt, who have a vast knowledge of this ransomware. We can help you in getting your network back up running.

CASE OUTCOMES

There is a high chance to get a working Conti decryptor after paying the attackers. But there’s never a guarantee to get a working decryption key at all. Since this is a new variant surfacing in June 2020, we still need more data to confirm whether or not a working decryptor is provided by attackers.

COMMON ATTACK VECTORS

It is in most cases either Remote Desktop Protocol or email Phishing are the 2 leading attack vectors. Unfortunately, even enterprises fail to secure their open RDP ports.

Due to an increase in remote working, a lot of employees now work from home using remote desktop control, leaving the company’s network exposed to hackers and all sorts of cyber criminals. But it isn’t limited to Remote Desktop Protocol.

In fact, the most common methods of this ransomware distribution is email phishing.

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.
