German cryptographer Karsten Nohl said he will reveal new findings on July 31 that indicate SIM cards contain encryption and software flaws, Forbes reported.
Nohl said he uncovered a two-part flaw after three years of research, and that it could allow hackers to infect SIM cards with a virus that sends premium text messages. If successfully carried out, the media outlet said, the flaw could cause payment system fraud in parts of the world where SIM cards play a vital role in this industry.
Nohl will present the research at the Black Hat security conference in Las Vegas, Nevada. For more on his statements regarding his research, read the full report here.
