October is Cybersecurity Awareness Month, and it’s a good time to think about how much the world has changed for chief information security officers (CISOs) in the last 12 months. A year ago, we thought we were already in the thick of AI and starting to understand it. Since then, agents have spread across the enterprise faster than most organizations anticipated. According to our Work Trend Index Annual Report, the number of active agents in the Microsoft 365 ecosystem grew 15-fold year over…

Agents are rapidly becoming part of how work gets done. They can support a range of activities from writing code and researching products to analyzing revenue, processing expenses, and acting across the systems that run the business. To be most useful, they often need access to company data, applications, tools, and other agents. That access is what makes agents more capable. With that capability can come insider risk. This does not mean agents are inherently malicious. It means they are…

[This is a Guest Diary by Zachary Norwood, an ISC intern as part of the SANS.edu BACS program] Crypto mining malware has been active and spreading across the internet for quite some time now. Moreover, the DShield honeypot picked up a worm that self-propagates through a plethora of means. One of them is stealing SSH keys after it gains access to a system. Furthermore, it also leverages a rootkit to maintain access to infected systems. One would hope that threat actors would have moved on past…

As these interactions become more common, securing agent-to-agent communication without blocking adoption will require…

You receive an invitation to a password-protected meeting, a secure chatroom, or a shared document. To get access, it says, you need to enter a short code on a sign-in page for one of your accounts. The message claims the code will let you open the document or join the meeting. In fact, it approves a sign-in the scammer started. The page is real and the code works, which is why this type of attack—known as device code phishing—is so dangerous. Device code phishing abuses a legitimate sign-in…

If your scan engine already holds credentials for a host, it can ask that host which ports are open instead of probing for them.Every scan begins with the same question: which ports on this host are open? Everything after it, from identifying services to checking for vulnerabilities to evaluating policy, depends on the answer being right. The traditional answer comes from the outside: the scan engine sends traffic to a range of ports and infers each port's state from how the host responds. That…
