Attackers are able to circumvent the entrance system and enter the building that utilises it thanks to a flaw in the intercom products made by Aiphone. One of the biggest manufacturers of intercom systems, including audio and video entrance systems for homes and businesses, is Aiphone.
A vulnerability found in numerous Aiphone products that might make it simple for an attacker to compromise the entry system using an NFC tag was reported last week by researchers from the Norwegian application security firm Promon.
