Microsoft on Tuesday disclosed that the latest string of attacks targeting SolarWinds Serv-U managed file transfer support with a now-patched remote code execution (RCE) exploit is the handiwork of a Chinese threat actor dubbed “DEV-0322.”
The revelation arrives days just after the Texas-based mostly IT monitoring software package maker issued fixes for the flaw that could help adversaries to remotely operate arbitrary code with privileges, letting them to complete actions like put in and run malicious payloads or look at and alter sensitive data.
Tracked as CVE-2021-35211, the RCE flaw resides in Serv-U’s implementation of the Secure Shell (SSH) protocol. Although it was earlier unveiled that the attacks ended up constrained in scope, SolarWinds said it can be “unaware of the identification of the perhaps impacted buyers.”

Attributing the intrusions with high assurance to DEV-0322 (small for “Enhancement Team 0322”) based on noticed victimology, practices, and treatments, Microsoft Menace Intelligence Centre (MSTIC) reported the adversary singled out entities in the U.S. Defense Industrial Base Sector and computer software firms.
“This action team is based in China and has been observed using commercial VPN methods and compromised customer routers in their attacker infrastructure,” in accordance to MSTIC, which discovered the zero-day right after it detected as many as 6 anomalous destructive processes currently being spawned from the main Serv-U method, suggesting a compromise.
The progress also marks the second time a China-based hacking group has exploited vulnerabilities in SolarWinds application as a fertile area for specific attacks in opposition to corporate networks.
Back in December 2020, Microsoft disclosed that a next espionage group could have been using gain of the IT infrastructure provider’s Orion computer software to drop a persistent backdoor known as Supernova on infected systems. The intrusions have considering that been attributed to a China-linked danger actor named Spiral.
Further indicators of compromise associated with the attack can be accessed from SolarWinds’ revised advisory in this article.
