"Nation-state snoops broke into Ribbon Communications - an outfit that provides software and networking gear to Verizon, CenturyLink, and the US Defense Department - last December, remained hidden for about nine months, and stole files belonging to three customers, according to the US telecommunications firm. "Ribbon prides itself on our long-standing partnerships with our customers and we know that security is a paramount concern within their networks," a spokesperson told The Register."
""Several customer files saved outside of the main network on two laptops do appear to have been accessed by the threat actor and those customers have been notified by the Company," according to the SEC filing. The company spokesperson confirmed the incident impacted three "smaller customers" but declined to name them or identify the sectors in which they operate. "A total of four older files were accessed" is all we've been told."
Ribbon Communications suffered a digital intrusion by actors reportedly associated with a nation-state. The attackers gained access to the company's IT network in December and remained undetected for about nine months until discovery in early September. Threat actors accessed four older files belonging to three smaller customers that were stored outside the main network on two laptops. The affected customers have been notified, but their names and sectors were not disclosed. Multiple third-party cybersecurity firms and federal law enforcement are assisting the investigation. Ribbon has implemented network security improvements and continues forensic efforts to confirm the extent of the compromise.
