Millions of devices are exposed to potential attacks exploiting the vulnerabilities used in the tools that threat actors recently stole from FireEye, security and compliance solutions provider Qualys reported on Tuesday.
Qualys said it identified more than 7.5 million instances related to vulnerabilities associated with the stolen FireEye tools and compromised versions of the SolarWinds Orion product. The vulnerable instances were discovered across nearly 5.3 million unique assets belonging to Qualys’ more than 15,000 customers.
As FireEye pointed out when it announced that threat actors breached its systems and stole some of its Red Team assessment tools, no zero-day vulnerabilities are exploited by these tools, which means patches and mitigations are available for each of the security holes. Now it’s up to impacted organizations to ensure that the vulnerabilities have been patched.
The stolen FireEye tools exploit 16 known vulnerabilities affecting products from Pulse Secure, Microsoft, Fortinet, Atlassian, Citrix, Zoho, and Adobe.
However, Qualys pointed out that a vast majority of the vulnerable instances (99.84%) are exposed to attacks due to eight critical and high-severity flaws affecting Microsoft products. Patching these issues can significantly reduce the attack surface.
Vulnerability remediation orchestration firm Vulcan Cyber has also shared a brief analysis of the FireEye tool vulnerabilities. Both Qualys and Vulcan Cyber have made available free tools and other resources that can help organizations address the security holes.
FireEye announced on December 8 that a highly sophisticated threat actor, which some believe is linked to Russia, had breached its corporate network and stole some of its Red Team hacking tools.
A few days later, it turned out that the attack on FireEye was related to a major cyber-espionage campaign targeting Texas-based IT management and monitoring solutions provider SolarWinds and its customers. SolarWinds has 300,000 customers worldwide, including many high-profile companies and government organizations.
The company says up to 18,000 may have been impacted as the attackers apparently only targeted customers of the Orion monitoring platform, by delivering trojanized updates for this product.
Several major companies have confirmed being affected, but they claim impact has been limited. It’s possible that U.S. government organizations may have been hit harder.
