Cybersecurity researchers have discovered a new hacking technique that exploits weaknesses in the eSIM technology used in modern smartphones, exposing users to severe risks.
The issues impact the Kigen eUICC card. According to the Irish company’s website, more than two billion SIMs in IoT devices have been enabled as of December 2020.
The findings come from Security Explorations, a research lab

NVIDIA is urging customers to enable System-level Error Correction Codes (ECC) as a defense against a variant of a RowHammer attack demonstrated against its graphics processing units (GPUs).
“Risk of successful exploitation from RowHammer attacks varies based on DRAM device, platform, design specification, and system settings,” the GPU maker said in an advisory released this week.

An Iranian-backed ransomware-as-a-service (RaaS) named Pay2Key has resurfaced in the wake of the Israel-Iran-U.S. conflict last month, offering bigger payouts to cybercriminals who launch attacks against Israel and the U.S.
The financially motivated scheme, now operating under the moniker Pay2Key.I2P, is assessed to be linked to a hacking group tracked as Fox Kitten (aka Lemon Sandstorm).
