Have intelligence agencies such as the NSA and GCHQ recovered the encryption keys of SIM cards produced by the group Gemalto, one of the world's leading suppliers, allowing them to easily and discreetly listen to conversations?
An article by The Intercept claims this after analysis of documents provided by Edward Snowden, again challenging the notion of information security passing through communications networks and highlighting listening methods which go beyond the protections in place without even having to break them.
The situation is embarrassing for Gemalto, a specialist in digital security solutions, who admitted to knowing nothing about the case and opened an internal investigation after the article was published, not formally refuting the information.
The Gemalto share price logically cashed the shock of these revelations last Friday and the action is again oriented downward at the opening of the stock market on Monday. In a new press release, the group announces that it will give a press conference this Wednesday February 25 to expose the results of its own investigations.
However, she points out that "the first conclusions already indicate that the SIM products (as well as bank cards, passports and other products and platforms) of Gemalto are safe and the Company does not expect to suffer significant financial damage".
