Forensic analysis of macOS Wi-Fi networks – reconstructing a Mac’s network connections
macOS manages information about known and currently connected Wi-Fi networks. Among other things, Apple allows users to view known networks, edit their settings and forget networks. Depending on the version of macOS and the system’s state, the relevant configuration and log records may be of interest for a forensic investigation.
However, a network saved as ‘known’ does not prove that the Mac was in a specific location at a specific time. Knowledge of a network, an actual connection and physical location are separate matters.
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 analyse available Wi-Fi configurations and network-related system artefacts. Known networks, technical identifiers, configuration references and time-stamped events are – where available – correlated with unified logs, DHCP/network traces, location services and other data sources.
No password or key material is required; the analysis focuses exclusively on the information that is actually accessible on the data source, which has been recorded in a manner that ensures the integrity of the evidence.
Typical areas of application
This is how the forensic investigation is carried out
Once the data has been securely backed up, existing Wi-Fi and network configurations are inventoried. Relevant SSIDs and technical network details are documented and cross-checked against available system logs.
Additional time-stamped records are required to draw specific conclusions about a connection. A known SSID on its own is not interpreted as evidence of a connection or as reliable proof of location.
Why is this area of investigation relevant to forensics?
Wi-Fi artefacts can be very helpful when reconstructing network and location contexts. For example, they can show that a network was known to the system or that further traces point to a connection.
However, the scope of such statements must remain limited. SSIDs are not globally unique; networks can be renamed or replicated, and saved configurations may remain in place long after they were last used.
