Prevents Supply Chain Attack
The SolarWinds hack, also known as the SolarWinds supply chain attack, when the attackers inserted malicious code into SolarWinds' software platform, which was distributed to approximately 18,000 customers through routine updates. The malicious code, known as SUNBURST, created a backdoor in the infected systems.
This allowed the attackers to install additional malware and exfiltrate data without being detected for an extended period of time. The attackers used obfuscation, legitimate network tools and credentials to exfiltrate data through DNS requests, making it harder to detect the malicious activity among normal network traffic.
