Forensic analysis of Linux ransomware – reconstructing encryption attacks on Linux systems
Linux systems, in particular Server and virtualisation infrastructures, are also increasingly becoming the target of targeted ransomware attacks, in which attackers carry out large-scale data encryption once they have compromised the system.
The forensic investigation of such an incident focuses both on reconstructing the initial attack vector and on documenting the extent of the damage for further business and legal assessment.
Why LanCologne?
Since its foundation, LanCologne has specialised in professional IT forensics. Our staff have decades of experience in the field of information technology and assist companies, solicitors, private individuals and, on a regular basis, the courts in the technical investigation of complex digital matters.
The examination is, as a matter of principle, carried out exclusively on a forensic copy, a forensic image or a data source captured in a technically equivalent manner that preserves the integrity of the evidence. The original evidence remains unchanged and is stored in a manner that preserves its integrity.
Our services
We reconstruct the sequence of events in a ransomware attack, from the initial compromise through to the actual encryption, identify the tools used, and document the extent of the damage in a manner admissible in court.
Typical areas of application
How a ransomware investigation is carried out
Once the affected systems have been secured, the initial method of compromise is first reconstructed using available logs and system artefacts. The tools used and the timeline of the encryption are then analysed, and any potential prior data exfiltration is investigated.
Why is the investigation into ransomware relevant from a forensic perspective?
A reliable reconstruction of the attack vector is essential for closing the exploited vulnerability and preventing further compromise, and is often a prerequisite for insurance payouts.
As many ransomware attacks also steal data prior to the actual encryption, checking for a previous data breach is an essential, separate investigative step with significant legal implications.
