In the previous post, we’ve discussed how passive OS identification can be done based on different network protocols. We’ve also used the OSI model to categorize the different indicators and prioritize them based on reliability and granularity. In this post, we will focus on the network and transport layers and introduce a machine learning OS identification model based on TCP/IP header values.

A WordPress plugin used on over 300,000 websites has been found to contain vulnerabilities that could allow hackers to seize control. Security researchers at Wordfence found two critical flaws in the POST SMTP Mailer plugin. The first flaw made it possible for attackers to reset the plugin's authentication API key and view sensitive logs (including password reset emails) on the affected website. A malicious hacker exploiting the flaw could access the key after triggering a password reset.
