![]() ![]() Customers with PAN-OS 10.0 or later are able to benefit from this new detection. Customers can then allow, block, or alert these detections based on their policy for handling Grayware. Strategically Aged Domain detection results are released in real time under the DNS Grayware category which is part of the Pan-OS 10.0 release. When will Strategically Aged Domain Detection be available in DNS Security? Subdomain DGA Detection to recognize any significant amount of emerging DGA sub-domain that could be used to exfiltrate the data out.ML-powered Domain Analysis to monitor domain statistics, activity during dormant state and traffic profile.Traffic Pattern Classifiers to identify abnormal burst of traffic.Our advanced cloud-based DNS security service leverages below filters to identify potential attacks using strategically aged domains: How Strategically Aged Domain Detection works? TheSolarWinds supply chain attack with SUNBURST trojan in December of 2020 utilized strategically aged domains along with domain generation algorithms (DGA) to bypass security controls and exfiltrate identities of the compromised hosts. Thereby, attackers gain an advantage from using these strategically aged domains for their attacks.įor example, Advanced Persistent Threat (APT) malware can stay dormant for years so they are deemed as benign, but then suddenly activate and produce a large amount of exploiting traffic through their command and control (C2) domains. Sometimes, it will take longer to detect when malicious activity begins as these domains have developed a benign reputation over time. The d omains are reserved and left dormant for months or even years before using them for attacking campaigns to bypass security vendor reputation checks. Strategically Aged Domains are domains that are registered in advance. However, it’s not enough to focus on threats behind NRD only as threat actors are coming up with advanced ways to evade existing protections. At Palo Alto Networks, we have mechanisms in place like monitoring DNS zone files and passive DNS data to detect these emerging malicious domains before a patient zero web threat appears. It’s well known that Newly Registered Domains (NRD) are widely used for various malicious activities. Palo Alto Networks’ DNS security service proactively identifies strategically aged domains based on traffic distribution, domain analysis and characteristics of the subdomain. Our latest protection identifies domains that have been intentionally aged to bypass security vendors reputation checks. This is why with Palo Alto Networks’ cloud-delivered DNS security service, we are constantly identifying new threats to secure your DNS traffic. ![]() Doctor 24By7s s Elite 2.0 is a local portable server that can work without the Internet.
