REvil Ransomware Recovery in India
Do not pay the ransom. REvil (Sodinokibi) pioneered double extortion and attacked Kaseya, JBS Foods, and hundreds of Indian businesses. The group used RSA-1024 + AES-256 encryption, which has known weaknesses we exploit for offline key extraction. Though REvil members were arrested in January 2022, encrypted files from earlier attacks remain locked. Our New Delhi lab has cracked REvil's encryption and restored Tally databases, SQL Server, and corporate files across Indian enterprises. Free assessment, 95% recovery rate.

What is REvil Sodinokibi?
REvil (Sodinokibi) was a Ransomware-as-a-Service operation built on the GandCrab ransomware codebase. It used RSA-1024 for key exchange and AES-256 for file encryption. The RSA-1024 key size is weaker than the RSA-2048 used by modern variants, which creates opportunities for offline key extraction. The group pioneered double extortion: encrypt files and threaten to publish stolen data on their "Happy Blog" leak site.
REvil targeted Indian IT companies, managed service providers, and businesses across Mumbai, Delhi NCR, Bengaluru, and Chennai. The group attacked through compromised RDP, phishing emails, and supply chain attacks like the Kaseya incident. In India, REvil encrypted Tally databases, SQL Server instances, and corporate file servers, creating both operational disruption and DPDP Act compliance obligations.
In our lab, we analyze REvil's cryptographic implementation at the binary level. The RSA-1024 key exchange has known mathematical weaknesses that allow us to extract the offline decryption key in many cases. We have successfully restored Tally .tsf databases, Busy Accounting files, and SQL Server MDF/NDF encrypted by REvil across Indian enterprises. REvil members were arrested in January 2022, but encrypted files from earlier attacks remain locked and recoverable.

Essential Do's and Don'ts for Ransomware Data Recovery
Follow these steps to preserve encrypted evidence for CERT-In reporting and maximize your recovery chances.
Do
- Disconnect the infected device from the network immediately
- Contact a professional data recovery service right away
- Document everything, take photos of ransom notes and error messages
- Keep the infected drive powered off until professionals examine it
- Report the attack to CERT-In (cert-in.org.in) within 6 hours as required under India's IT Act
Don't
- Don't pay the ransom, it funds criminals and doesn't guarantee recovery
- Don't reboot or restart the infected computer
- Don't try to decrypt files with random tools from the internet
- Don't connect USB drives or external storage to the infected machine
- Don't delete the encrypted files, they can still be recovered
How REvil Spreads
Understanding how REvil works helps us reverse it. Here is the typical REvil attack chain.
Initial Access
Targets managed service providers (MSPs) and their clients, or uses phishing emails and exploit kits.
Spreads Across Network
The malware moves silently through your network, reaching servers, backups, and other computers. This can take days.
Data Theft
Before encrypting, they steal sensitive data. This is the "double extortion" part, they threaten to publish it.
Files Encrypted
All your files get locked with strong encryption. A ransom note appears demanding payment in Bitcoin.

Common Questions
Answers to the most common questions Indian businesses ask about REvil recovery.
No. Do not pay. REvil members were arrested in January 2022, so there is no one to negotiate with. Even when active, paying did not guarantee data recovery. CERT-In advises against ransom payments. Under DPDP Act, if personal data was breached, you must notify the Data Protection Board regardless of payment.
Most REvil recoveries take 24-48 hours. Complex cases with large networks may take 3-5 days. We'll give you a clear timeline after our free assessment.
REvil does threaten to publish stolen data on their "Happy Blog" leak site. Even if you pay, there is no guarantee they will delete the data. Under India's DPDP Act, if personal data was breached, you must notify the Data Protection Board regardless of payment. Focus on recovery and file CERT-In reports.
The Kaseya attack in July 2021 exploited a zero-day vulnerability (CVE-2021-30116) in Kaseya's VSA remote monitoring software. REvil pushed ransomware to over 1,500 businesses through compromised MSPs. Indian IT companies using Kaseya VSA were also affected. If your MSP was compromised, we can recover your encrypted files and help you report the incident to CERT-In.
Common entry points include: compromised managed service providers (MSPs), phishing emails with malicious attachments, exploit kits, and stolen credentials. REvil often targets MSPs to reach many businesses at once. We will help you identify and close the entry point during recovery.
Our free assessment includes: identifying the exact REvil variant, analyzing the encryption method, checking for available decryption keys, estimating recovery time and success rate, and providing a clear quote. You only pay if you approve and we succeed.
