DotW: URL Wildcard Pattern

As the world continues dealing with a pandemic involving the coronavirus disease COVIDmalicious campaigns are well underway. Attacks are more likely to be successful today due to the added risk of widespread work-from-home policies. This blog post will explore how you can use domain classification to identify young domains and how you can flip the advantage to defenders by using the Palo Alto Networks and the LogRhythm NextGen SIEM Platform integration. Attackers that use Domain Generating Algorithms DGA have an advantage in creating campaigns that prey on novel news stories. This is especially true in the current environment because these news stories are global. Others incorporate a seed value as well to make predicting future domains more difficult for defenders. You can easily use them to not only obtain insight into suspicious domains but also actively block them. If Palo Alto Networks is configured to alert on young domains, rather than block, it may be that you are correlating with other log sources to perform broader analytics that results in an AI Engine alert indicating a malicious young domain with a high degree of certainty. In this case, you may wish to proactively block that domain on the Palo Alto Networks device. LogRhythm has a great discussion on Community discussing how to use dynamic block lists in Palo Alto Networks here. Detecting malicious, nefarious, and otherwise unwanted URLs poses a big challenge with newly created domains. How would you rank the maturity of your security operations?
