Recently, I had to extract embedded files from a set of OneNote files (extension .one). My onedump.py tool can extract individual files, so I would have to run this many times. To avoid this, I added a new feature to my onedump.py tool: producing JSON data. Several of my tools already have such a feature: they produce JSON data with the content of their analysis results. onedump's option --jsonoutput produces JSON output with the content of each embedded file found inside the OneNote file. And…

A modern organization protects its information systems with a whole suite of technologies that generate thousands of security alerts every day. Looking at these alerts in bulk, you’ll see that a significant share are false positives. Ideally, these alerts would be filtered out automatically so that analysts could focus on the ones that may point to a real incident. However, writing filters is a time-consuming task in itself. To create a correct filter, an analyst needs to: Review the logs…

Building your malware analysis lab is a key point before playing with malware. Today, thanks to virtualization, it's convenient to play with snapshots in your lab. Start a new investigation from a clean snapshot and take some more when you reached a critical step. But, if you need to revert to a previous snapshot, all changes applied to the VM are... lost! Therefore, it's important to store important data outside the VM. If you do malware analysis with Ghidra[1], your work lives in "projects".…

Executive Summary Node.js has fixed CVE-2026-111497, a Brotli decoder flaw that can permit remote code execution, in 22.23.4, 24.22.1, and 26.12.1, but upgrading at scale is slow. In Qualys telemetry, only 42,000 of roughly 3 million Node.js installations have been patched, and 1.7 million run end-of-life lines that will never receive a fix. In the meantime, interim mitigations from the Qualys Threat Research Unit narrow the Brotli, DNS, TLS, and keep-alive attack paths, and WAF, IPS, and EDR…
Elections give scammers plenty to work with: urgent deadlines, familiar faces, passionate supporters, and messages asking people to take action. Some want you to “fix” your voter registration. Others want a donation, an answer to a survey, or payment for merchandise supposedly endorsed by your favorite politician. The details change, but the objective stays the same: get your money, your personal information, or both. Here are five election-themed scams to watch out for. Scam 1. “We’ll help you…

You recognize the website. You’ve visited it before. You may even have it bookmarked. Then it asks you to do something unusual: install an update, allow notifications, or run a command to prove you’re human. Stop and check first. A website you trust can still display instructions you shouldn’t follow. Our researchers have documented attacks in which criminals hacked legitimate websites and used them to deliver fake verification pages that trick visitors into installing malware. Within the same…

Introduction AI agents and associated tooling are becoming increasingly common in corporate infrastructure. Agents can perform a range of actions with the user’s privileges, such as accessing data, running commands, and interacting with external services. This creates new security risks, especially when these tools are used without the security team’s oversight or well-designed policies. Detecting, tracking, and controlling AI agents is becoming one of the most pressing tasks for security teams…
[This is a Guest Diary by Jeffray Spence, an ISC intern as part of the SANS.edu BACS program] Around Here, we start our day with coffee, but our day does not begin until we have our data...So much data. Where to even begin? When approaching a massive dataset, such as those from a DShield SIEM Honeypot, the first step is to actually find something to analyze. As for myself, I usually go looking for something that makes me go; "Huh." Today we will be walking through a starting approach with…
