The cellphone can allegedly be hacked in order to facilitate unlawful on-line banking transfers, in line with the Dutch firm Ultrascan Superior International Investigations.

Often, the final cellphone that used the community would be the one which receives inbound messages, he mentioned.

“So if this specific Nokia 1100 will be modified to spoof the victims cellphone quantity, it needs to be attainable to develop into the first handset — a minimum of lengthy sufficient to obtain the TAN,” Smith mentioned.

Technical particulars on how the 1100 is being modified are nonetheless unknown, mentioned Frank Engelsman of Ultrascan. Nevertheless, a girl in Finland contacted his firm on Monday after seeing a information story and supplied to ship her Bochum-made Nokia 1100. When it arrives, the cellphone might be examined and examined to see if the TAN interception will be replicated, Engelsman mentioned.

In the meantime, a Dutch know-how web site, portablegear.nl, wrote that it positioned a faux commercial for the actual Nokia 1100 on a web based market. Folks supplied as a lot as €500, providing to right away come decide up the machine.
