Srinivasan Krishnappa

Srinivasan Krishnappa is the ransomware and database recovery engineer behind AS. He has handled and resolved more than 656 ransomware recovery cases across a wide range of industries and technology environments, working with ransomware families and variants including LockBit, LockBit 3.0, Locky, Makop, Akira, Everest, Play, Medusa, among many others.

His work spans complex enterprise environments — VMware ESXi and virtual-machine recovery, Veeam Backup and VBK recovery, Microsoft SQL Server, SAP and SAP HANA, Microsoft Dynamics NAV, Focus ERP, hospital information systems (HMIS) and other large-scale database and ERP applications — for hospitals, universities, export companies, manufacturers and other enterprises running mission-critical systems.

His specialization goes beyond conventional file recovery: he works at the database and backend-structure level, analysing and reconstructing database structures, tables and relationships, indexes, metadata, database pages, headers and allocation structures, along with corrupted database objects, damaged records, virtual-machine storage and backup structures. Because enterprise applications ultimately depend on their underlying databases, understanding those internal structures and relationships is what makes advanced recovery possible.

He builds each recovery approach from the actual condition of the underlying data — from complex database corruption and ransomware damage to backup and virtual-machine failures. AS is deliberately a one-person practice: the engineer who assesses your case is the one who does the recovery, and every case begins with an honest assessment of what is realistically recoverable. Where data cannot be brought back, he says so — there are no guaranteed-recovery claims here, because no one can honestly make them.

The technical posts published here come from that casework: what to do in the first hour, what makes a situation worse, and what an assessment can realistically establish.
