UPDATE SonicWall said a zero-day in its SMA 100 series 10.x code was targeted by “highly-sophisticated” attackers. The security company initially said it is currently investigating its Secure Mobile Access (SMA) 100 series hardware for potential vulnerabilities linked to a reported cyberattack. SMA 100 is a gateway for small- and medium-sized businesses that lets authorized users access resources remotely. SMA 100 also gives system administrators visibility into remote devices that are connecting to the corporate network – and grants endpoints access based on corporate policies. “On Sunday, January 31, 2021, the NCC Group alerted the SonicWall Product Security Incident Response Team (PSIRT) about a potential zero-day vulnerability in the SMA 100 series. Our engineering team confirmed their submission as a critical zero-day in the SMA 100 series 10.x code,” said SonicWall in an updated statement.
