Today, Talos is publishing a glimpse into the most prevalent threats we've observed between Sept. 23 and Sept. 30. As with previous roundups, this post isn't meant to be an in-depth analysis. Instead, this post will summarize the threats we've observed by highlighting key behavioral characteristics, indicators of compromise, and discussing how our customers are automatically protected from these threats. As a reminder, the information provided for the following threats in this post is non-exhaustive and current as of the date of publication. Additionally, please keep in mind that IOC searching is only one part of threat hunting. Spotting a single IOC does not necessarily indicate maliciousness. Detection and coverage for the following threats is subject to updates, pending additional threat or vulnerability analysis. For the most current information, please refer to your Firepower Management Center, Snort.org, or ClamAV.net. For each threat described below, this blog post only lists...

Gridea version 0.9.3 allows an external attacker to execute arbitrary code remotely on any client attempting to view a malicious markdown file through Gridea. This is possible because the application has the 'nodeIntegration' option enabled.
