SIM Card Hack Fixed Remotely by Carriers

We reported a few weeks ago about the vulnerability found in a possible 750M phone SIM cards, leaving the cards prone to a hack. Carriers found a reverse exploit and pushed it out in an update effectively patching the vulnerability.

Physically replacing millions of SIM cards would’ve been an expensive and painstaking task by carriers, but instead, they took advantage of the same Java vulnerability that Nohl found and used it to hack into their own SIM cards and patch the exploit.
