Vodafone's online sales of "Callya" prepaid cards were impacted by the purported ransomware attack on the IT service company Materna.
The Vodafone website stopped selling the SIM cards, just after Materna had given the business permission to launch a "professionally elaborated cyber attack.
Both businesses emphasise that there hasn't been any determination of a consumer data leak. "Restrictions on online sales and online registration of Callya products" should be lifted soon, according to Vodafone. Until then, there would be other ways to make the reservation.
Many clients' systems were also impacted by the Materna security breach. There were Materna-operated check-in machine outages at several German airports.
Workers were "equipped with newly installed or completely newly configured systems," which had never been linked to the impacted infrastructure.
