Ransomware in Chennai: what gets hit

Chennai's automobile and component plants along the Sriperumbudur–Oragadam corridor, IT parks on OMR, hospitals, logistics firms at the port and thousands of traders and distributors all run on databases: SQL Server behind ERP and hospital systems, Tally, Busy and Marg for accounts and billing, and VMware or Hyper-V servers with backups on the same network. Ransomware usually hits all of them in one night. Large database and virtual disk files are often only partly encrypted, which is where recovery comes from.

How a case from Chennai works

1. Remote assessment

Send us the ransom note and a few encrypted files. We identify the ransomware and measure how the files were encrypted — often within hours.

2. Files or media to our lab

Copies of the encrypted databases, virtual disks or backups — or the drives themselves — come to our lab in Dharmapuri. Originals are only ever read.

3. Recovery and validation

We recover what the encryption left intact and check it before handing it back, reporting plainly what could not be recovered.

Getting to our lab from Chennai

Chennai is in our own state. Media can be brought to Dharmapuri by road on NH48 via Vellore and Krishnagiri, about 300 km or around five to six hours, or sent by courier, usually arriving the next day. Most cases do not need the hardware at all: copies of the encrypted files are enough to start. Visits and drop-offs are by appointment.

Address and directions

Why encrypted does not always mean lost

To finish quickly, most modern ransomware encrypts only parts of large files — the start, or chunks at intervals. Databases, virtual disks and backup files therefore often keep most of their real content. Some of our measured cases:

96 million rows from a 27 GB encrypted SQL Server databaseEvery other page in the first and last 2.5 MB was encrypted; 222 tables recovered, 179 of them complete.466 GB server disk rebuilt from an Akira-encrypted Veeam backupThe header and first metadata of the 43 GB backup were encrypted; 98% of its data blocks were verified intact and the disk was rebuilt.LockBit 3.0: only 3.76% of a 1.1 GB file encryptedMeasured byte by byte against an unencrypted copy — the rest of the file was untouched.

We have solved 656+ ransomware and data recovery cases. Results depend on how each file was encrypted, and we tell you exactly what is recoverable after a free assessment, before you pay anything.

Reporting rules in India

CERT-In's April 2022 directions require organisations to report cyber incidents, including ransomware, to CERT-In within six hours of noticing them. If personal data is affected, the Digital Personal Data Protection Act, 2023 also requires the breach to be reported to the Data Protection Board and to the people affected. This is general information, not legal advice — check your obligations early, because the clock starts when the incident is noticed.

Frequently asked questions

Do you have an office in Chennai?

Our lab is in Dharmapuri, Tamil Nadu, about five to six hours from Chennai by road. Ransomware recovery works from copies of the encrypted files, so we start remotely the same day, and media can be couriered overnight.

Our Tally and Busy data were encrypted. Can you recover them?

Yes, we have recovered many encrypted and damaged Tally, Busy and Marg ERP data sets. We check each company's data files and tell you exactly what is recoverable after a free assessment.

What if nothing can be recovered?

Then you do not pay for the recovery. The assessment is free, and we tell you what is recoverable before any work is charged.
