![]() ![]() The traffic to the malicious domains is disguised as SolarWinds API data.įrom there, they had access to software which inherently provides them access to network communications of SolarWinds clients. Essentially, they used the host names of valid services. The DNS then responds with a CNAME record aimed at a Command and Control server. After a couple weeks, the trojan tries to resolve a avsvmcloudcom subdomain. #TEAMCITY HACK UPDATE#Once SolarWinds downloaded the update to their Orion software, the (normal) BusinessLayerHost.exe would load the trojanized DLL file. They proceeded to post these corrupted updates to the SolarWinds site with a legitimate signature. #TEAMCITY HACK PATCH#The actors created a Windows Installer Patch file including a backdoored version of a standard solarwinds update file. In that respect, I think it’s valuable to review how it happened. They win points for detecting the breach when no one else did, but if they couldn’t prevent it, what chance do average teams have? With hardware access, bad actors can do things like interfere with energy infrastructure, for example.īut perhaps the greatest takeaway is that even a top cybersecurity firm was breached. Specifically, hardware data follows employee data which follows company data. Unless you’re in cybersecurity ops (and if you are… you have our condolences), the primary concerns are: interference with the government, theft of intellectual property, and disruption of operations. It was not limited to the United States Europe, Asia, and the middle east were also affected. In total, potentially thousands of organizations have been penetrated by the malware. In the private sector, Cisco, Intel, VMware, Microsoft, and Nvidia, among others, were also breached. FireEye, a large cybersecurity firm, was also compromised. Several departments of the government were compromised, including the treasury, homeland security, commerce, defense, energy, state, and health departments. And yet, Solarwinds was the catalyst for a string of network breaches the likes of which hasn’t been seen in a long time, if ever. With revenues just under a billion dollars, this is not a behemoth of industry like IBM or Microsoft. Solarwinds is one of many seemingly innocuous network monitoring softwares. ![]()
