Command-and-Control Server: OSINT-based detection – forensic documentation of publicly visible control servers

Malware frequently communicates with so-called command-and-control servers, the technical characteristics of which can, in certain cases, be traced via publicly available sources and scan data.

Enquire without obligation

As part of existing incident response cases, we conduct structured investigations to identify publicly visible indications of such control servers.

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.

Our OSINT investigations are always carried out as a complementary component to existing IT forensic, legal or internal corporate enquiries. Every step of the investigation and every piece of digital evidence found is documented and, where technically possible, archived to ensure traceability even if the original online content is subsequently altered or deleted.

Our services

We investigate publicly available technical indicators relating to a relevant command-and-control Server and document the findings in a manner that is forensically verifiable.

Typical areas of application

•Identification of publicly visible control servers following a malware incident

•Supplementing incident response investigations

•Support in assessing the severity of an attack

•Comparison with known threat databases

•Judicial and non-judicial expert reports

•Collaboration with IT security teams

This is how a Command-and-Control-Server investigation works

Based on technical indicators from the system analysis, Shodan is used to carry out a targeted search for publicly visible, relevant Servern instances, and the findings are cross-referenced with other publicly available threat intelligence.

Why is the Command-and-Control Server investigation relevant from a forensic perspective?

Identifying a command-and-control server can provide important clues as to how an attack works and its scope.

The documented findings also support coordination with IT security service providers to further secure the affected systems.

Frequently Asked Questions

Can every Command-and-Control Server be publicly identified?+

No, many Server cases cannot be found via publicly available sources; we communicate the existing limitations of our investigations transparently.

Is the technical analysis of the malware carried out in-house?+

This is carried out as part of the forensic system investigation; our OSINT research supplements this with publicly available infrastructure information.

Are any Server units found reported?+

The forensic documentation may serve as the basis for a report by the client to the relevant authorities.
