Inform the Certifying Authority (CA) Immediately

• The first step is to notify the Certifying Authority that issued the Digital Signature Certificate (DSC).
  
• Provide a written complaint including the certificate holder’s name, certificate number, and misuse details.
  
• Request for immediate suspension or revocation of the DSC to prevent further fraudulent use.
  
• The CA may ask for additional identification and supporting documents.
  
• Prompt reporting ensures the certificate is disabled quickly and misuse is contained.
  

File a Complaint with the Cybercrime Cell

• Lodge a formal complaint with the local cybercrime police station or designated IT cell.
  
• Clearly describe the misuse, such as unauthorized access, forgery, or impersonation.
  
• Attach all relevant evidence such as emails, signed documents, logs, or screenshots.
  
• The complaint should include personal and DSC details of both the victim and the suspected offender.
  
• Law enforcement may initiate investigations and legal proceedings under applicable laws.
  

Notify the Concerned Organization or Platform

• If the misuse occurred on a government or private portal, report the issue to the platform’s compliance or grievance cell.
  
• Provide reference numbers, screenshots, or document IDs where the fraudulent signature was used.
  
• The platform may temporarily block access and coordinate with authorities.
  
• Reporting at the platform level helps stop further unauthorized actions.
  
• Keep a record of all correspondence for future reference.
  

Document and Preserve All Evidence

• Retain copies of the DSC, usage logs, communication, and any impacted files.
  
• This documentation is essential for legal, forensic, and administrative follow-ups.
  
• Save system logs or audit trails that show unauthorized access or actions.
  
• Secure the original digital documents involved in the misuse.
  
• All this evidence will support any formal inquiry or litigation.
  

Follow Up on Complaint Status

• Track the status of your complaint with the Certifying Authority and the cybercrime unit.
  
• If needed, escalate the matter to higher officials or digital grievance redressal forums.
  
• Request written confirmation of certificate revocation and inquiry initiation.
  
• Maintain regular communication to ensure the matter is progressing.
  
• Cooperate with investigators and provide any further inputs when requested.
