Telephone Surveillance | Tapped Telephones | Telephone Tapping

It is the proverbial crackling in the line that prompts many of our clients to commission bugging countermeasures. Even today, long-term surveillance measures are still predominantly carried out via wired connections. Telephone lines are of course ideally suited for this purpose. However, it is not only lines that can be tapped: the telephone handset itself is particularly suitable as a container for placing a bug.

Mobile Phone Check | Mobile Phone Bugging Countermeasures

Mobile telephones, particularly in the form of smartphones, are becoming an increasingly popular target for bugging attacks. Unlike conventional telephone devices, this involves software that can be influenced through software programmes and hacking attacks. Physical bugging attacks – that is, through hardware modification – practically do not occur with smartphones and therefore are not a core field of our Bugging Countermeasures and Eavesdropping Protection department.

 

However, we also offer competent solutions for this and refer you regarding the topics of smartphone forensics and smartphone security to the IT Forensics and IT Security department of the Kurtz Detective Agency:

Intercepted Faxes | Manipulated Fax Machines

Naturally, not only telephone systems are affected by surveillance measures, but also printers, scanners, copiers, and fax machines connected to networks, which often run via the same lines. The surveillance technology is installed within the devices themselves or at distribution boxes or directly on the cables. Bugging countermeasures on fax machines are just as much a core field of our Eavesdropping Protection and Bugging Countermeasures department as the detection of all other physical bugging measures.

 

Wireless networks are naturally generally susceptible to eavesdropping attacks. Responsible bugging countermeasures in this area must be software-based and implemented by professional IT forensic experts.
