Actionable Threat Intelligence Available for Sunburst Cyber Attacks on SolarWinds

<p>On Dec. 13, FireEye published a <a href="" target="_blank">detailed analysis</a> about the attack carried out against SolarWinds, which appears to have compromised its Orion IT monitoring and management platform to spread the Sunburst Backdoor malware. As part of the attack, which started in March, the Orion platform started sending out the digitally-signed trojanized malware via regular updates. According to SolarWinds, <a href="" target="_blank">the compromised update may have been installed by fewer than 18,000 of its customers</a>, including many U.S. federal agencies and Fortune 500 firms that use Orion to monitor the health of their IT networks. In a related blog post, <a href="" target="_blank">FireEye also announced</a> that a highly sophisticated state-sponsored adversary penetrated its network and stole FireEye Red Team tools used to test customers’ security.</p> <p>In response to the attacks, Anomali has collected, curated, and distributed clear and concise open-source intelligence (OSINT) to help organizations determine if they have been impacted. Two key resources released include a <a href="" target="_blank">SolarWinds Breach Threat Bulletin</a> and a <a href="" target="_blank">FireEye Red Team Tools Breach Threat Bulletin</a>. These continually updated resources, for use inside Anomali ThreatStream, include threat analysis, signature threat models, and over 2,000 operationalized indicators of compromise (IOCs) for automated distribution to security controls. Both are available now to Anomali’s 1,500 customers.</p> <h2>What Can I Do with This Threat Intelligence?...and How to Do It</h2> <p>Our intent in aggregating and curating this threat intelligence is to provide organizations with high-fidelity IOCs that can immediately be pushed into their security stacks for rapid, proactive blocking and alerting. Security products that can take advantage of this actionable threat intelligence include security information and event management (SIEM), endpoint detection and response platforms, firewalls, domain name system (DNS) servers, security orchestration, automation, and response (SOAR) platforms, and other operational security products.</p> <p>These Anomali threat bulletins are designed to be used in conjunction with Anomali ThreatStream, a threat intelligence platform that allows organizations to aggregate, curate, analyze, and distribute multiple sources of threat intelligence to their operational security systems. Inside of the SolarWinds Breach Threat Bulletin, all of these IOCs have been tagged with “solarwinds”, “sunburst backdoor”, “unc2452”, or “” This enables ThreatStream users to create a simple rule to automatically push IOCs to their security systems, enabling real-time defense against both attacks. For example, if a compromised server inside the organization attempts to connect to a command and control (C2) server outside of the organization, Anomali customers that have activated this research will automatically block the C2 URL, avoiding risk of further compromise and data exfiltration.</p> <h2>How Can I Get This Intelligence?</h2> <p>The Anomali SolarWinds and FireEye Threat Bulletins are automatically available to Anomali’s ThreatStream customers, and all organizations participating in Anomali-powered threat intelligence sharing communities (ISACs).</p> <p>Anomali Threat Research also created a <a href="{page_5173}">custom dashboard within ThreatStream</a> which empowers customers to immediately detect IOCs present in their environments, quickly produce bulletins to operationalize threat intelligence across their security infrastructures, and communicate to all impacted stakeholders.</p> <h2>Curated OSINT Available to All Organizations</h2> <p>For organizations that aren’t Anomali customers, we have made <a href="{page_5171}">static versions of the open source threat intelligence available here</a>. While these downloads won’t be dynamically updated, they do provide valuable, actionable intelligence that can be leveraged to improve defenses.</p> <p>At Anomali, our goal is to help organizations be more secure by leveraging threat intelligence, which is now more important than ever. Only through massive intelligence collection and sharing can we stay ahead of real-world and cyber threats. So, let’s get to work!</p> <div class="text-center" style="-webkit-border-radius: 10px;-moz-border-radius: 10px;border-radius: 10px;margin-bottom:30px;padding:25px;background-image: url(/images/uploads/backgrounds/bg-sunburstv2.jpg);background-size: cover;background-position: center;"> <h3 class="text-white">Get Actionable Sunburst Threat Intelligence Today!</h3> <a class="btn btn-anomali btn-sm" href="{page_5171}" target="_blank">Download Now</a></div>
