leak allegations According to documents leaked by Edward Snowden, NSA's and GCHQ's Mobile Handset Exploitation Team infiltrated Gemalto's infrastructure to steal SIM authentication keys, allowing them to secretly monitor mobile communications. GCHQ codenamed the program "DAPINO GAMMA". The secret GCHQ document leaked by Snowden also claimed the ability to manipulate billing records to conceal their own activity and having access to authentication servers to decrypt voice calls and text messages. Snowden stated that "When the NSA and GCHQ compromised the security of potentially billions of phones (3g/4g encryption relies on the shared secret resident on the sim), they not only screwed the manufacturer, they screwed all of us, because the only way to address the security compromise is to recall and replace every SIM sold by Gemalto." The breach subsequently refueled suspicions against Gemalto chairman Alex J. Mandl, given his role in the CIA venture capital firm In-Q-Tel. GCHQ and NSA declined to comment on the matter. Gemalto issued a press release on February 25, 2015 saying there were "reasonable grounds to believe that an operation by NSA and GCHQ probably happened", but denying that the government agencies gained access to any authentication keys. Smart card weak key vulnerability In October 2017, it was reported that Gemalto's IDPrime.NET smart cards, which are used internally by Microsoft and many other companies, were affected by the Infineon weak key vulnerability, leaving their private keys deducible to attackers. Partnerships Key partners of Gemalto include Wipro, Prodapt, Maya, Sendum, Unique Computing Solutions, Symphony Teleca, Bing, Kore, West, etc. In 2017, OnKöl, a home care hub device started using Gemalto's M2M Module.
