Description:
For nine months, the group lurked, exfiltrating sensitive data and
potentially moving to other networks, as well.

FULL STORY

A Chinese state-sponsored threat actor known as Salt Typhoon was lurking in
the network of the US Army National Guard for nine months, the US Government has confirmed.

TheDepartment of Homeland Security (DHS) said the attackers were present in
the networks between March and December 2024.

During this time, the group stole sensitive data from its victims, including administrator credentials, network traffic diagrams, geographical maps, and personally identifiable information (PII) of service members. Furthermore,
the attackers accessed data traffic between the states network and every
other US state, and at least four additional territories. This means that
they could have pivoted to other networks as well, compromising even more government and military targets.

Typhoon over America

It was not discussed how the breach happened, but DHS did say the group was known for exploiting existing vulnerabilities (CVEs) in Ciscos routers and similar hardware.

Salt Typhoon is a known Chinese state-sponsored threat actor, part of the
wider typhoon organization that includes groups such as Brass Typhoon, Volt Typhoon, and others.

These organizations were tasked with infiltrating different core
organizations within the US, such as critical infrastructure organizations, communications firms, government, military, and defense organizations, and similar.

The goal of the campaign was to be present inside the networks should
tensions between the US and China over Taiwan escalate into a full-blown war, giving it the ability to disrupt networks, and steal key intelligence.

Salt Typhoon is often in the media - with recent attacks against the likes of AT&T, Verizon, Lumen, Charter, Windstream, and Viasat, to name a few, often abusing unpatched Cisco routers to gain access, before deploying custom
malware such as JumblePath and GhostSpider.
