[4 minuty čtení] Útoky typu SIM swap jsou často velmi propracované a vždy nepříjemné pro majitele telefonního čísla. Přitom běžný uživatel nemůže uhlídat všechny cesty k útoku vedoucí. T-Mobile má na krku další takový. Telekomunikační obr T-Mobile zveřejnil před pár týdny informace o datovém průlomu do svých systému, který vedl k tomu, že někteří jeho uživatelé se stali obětí útoku typu SIM swap. Mechanismus toho, jak se lze dopracovat k tomu, aby útočníkovi operátor zpřístupnil SIM třetí osoby, je popsán třeba na Wikipedii. Dodat tak lze hlavně to, že s rostoucím významem mobilních telefonů v komunikaci, kdy je SIM / číslo párováno uživatelem s přístupem ke stále rostoucímu počtu služeb, nebezpečnost tohoto typu útoku rozhodně neklesá, spíše naopak.
