Chinese Hackers Breach US Internet Firms via Startup, Lumen Says

The state-sponsored Chinese hacking campaign known as Volt Typhoon is exploiting a bug in a California-based startup to hack American and Indian internet companies, according to security researchers. From a report: Volt Typhoon has breached four US firms, including internet service providers, and another in India through a vulnerability in a Versa Networks server product, according to Lumen's unit Black Lotus Labs. Their assessment, much of which was published in a blog post on Tuesday, found with "moderate confidence" that Volt Typhoon was behind the breaches of unpatched Versa systems and said exploitation was likely ongoing. Versa, which makes software that manages network configurations and has attracted investment from Blackrock and Sequoia Capital, announced the bug last week and offered a patch and other mitigations. The revelation will add to concerns over the susceptibility of US critical infrastructure to cyberattacks. The US this year accused Volt Typhoon of infiltrating networks that operate critical US services, including some of the country's water facilities, power grid and communications sectors, in order to cause disruptions during a future crisis, such as an invasion of Taiwan.
