Breach & Malware Remediation
Remediation must address both the immediate threat and the conditions that allowed it. Cleaning without understanding leaves the environment vulnerable to recurrence.
When this service is needed
- —Confirmed malware infection on servers or endpoints
- —Compromised web applications serving malicious content
- —Web shells or backdoors discovered on infrastructure
- —Post-investigation remediation following a breach
- —Persistent threat requiring thorough environment cleanup
- —Cloud environment compromise requiring secure restoration
What we investigate
- —Malicious files, scripts, and executables
- —Persistence mechanisms across systems
- —Modified configurations and unauthorized accounts
- —Compromised credentials requiring rotation
- —Network-level indicators of compromise
- —Related systems that may share the same compromise
Methodology
Identify
Locate all malicious components and persistence mechanisms.
Contain
Isolate affected systems to prevent further spread.
Remove
Eliminate malicious code, accounts, and configurations.
Verify
Confirm remediation completeness through technical validation.
Strengthen
Address weaknesses that enabled the compromise.
Typical deliverables
- —Remediation plan and execution guidance
- —Verification of malicious component removal
- —Credential rotation recommendations
- —Hardening recommendations
- —Post-remediation validation report
Frequently asked questions
Should we reinstall affected systems?
Reinstallation may be appropriate after evidence preservation. The decision depends on incident scope, system criticality, and whether sufficient evidence has been collected.
How do we know remediation is complete?
Complete remediation requires verifying that all identified malicious components are removed, persistence mechanisms are eliminated, and related systems have been assessed.

Why Reinstalling a Compromised Server Can Destroy Evidence
Reinstalling feels like the fastest path to recovery. It also removes the artefacts investigators need to determine entry points, persistence mechanisms and scope.
