Hello and welcome to the Tuesday, May 5, 2026 edition of the sans Internet Stormcenters Stormcast. My name is Johannes Ulrich, recording today from Jacksonville, Florida, and this episode is brought to you by the Sans Edu Graduate Certificate Program in Penetration Testing and Ethical Hacking. Well, in diaries today I gave a little update on the D shield honeypot I released today, a VERS that will actually allow you to run it on the latest version of Ubuntu 2604. There was only one minor adjustment I have to make and it only affected the minimum install of Ubuntu. So if you have one of the normal server installs, well, it should just work out of the box before you Upgrade to Ubuntu 2604. Realize that some of the base utilities of Linux, like Move, RM and the like, they were rewritten in Rust in that version and apparently it had actually led to some other vulnerabilities, like some time of check, time of use vulnerabilities. So not necessarily recommending that you're upgrading to 2604. And for now we definitely will still support 2404 in particular since they are so similar. But if you have a new 26.04 system, well, the honeypot should just work nicely on it. Also making some adjustments to Kauri that'll take a little bit longer. There was one odd sort of encoding issue where some of the API keys weren't used correctly. So if you do observe that your SSH and Telnet reports are not being reported to us, well, let me know and I can walk you through how to fix it. But that'll probably come in the next couple days as an official update to the Honeypot, including sort of a little bit of revamp of Kauri itself. Kauri, if you're not familiar with it, that's the Python script we're to simulate Telnet and ssh. Great little honeypot, and definitely a very useful tool for us. And Progress, the maker of the file management software Moovit, has released their April update fixing two different vulnerabilities. One is rated high, one is rated critical. Well, the end result is that you have authentication bypass issues through the service backend command port interfaces. I don't think they need to be exposed. So that's something to look at to further maybe protect those interfaces, those IP addresses from external access. But please refer to the details here. From Progress on how to properly configure MoveIt. I'm not that familiar with this particular piece of software. Either way, no real sort of additional items here from progress as to what else you could do but patch. So go ahead and patch. The reason I cover this software is that in the past it has been used to deploy ransomware. So it's certainly on the radar of the bad guys and they may already be working on an exploit. And then we have an update for the Apache HTTP server. This update isn't so far significant that it fixes, yes, a number of vulnerabilities, but one in particular could possibly lead to remote code execution. It's part of the HTTP 2 module, so something that's often enabled. However, and that's a big sort of constraint here is only one specific version is affected 2466 that's the version prior to today's version, version 2467. So only if you downloaded this very specific version, which you probably then downloaded from the Apache itself and compiled from source only, then your vulnerable. Most distributions fix themselves sort of on, you know, a particular version and then just sort of apply some bug fixes, security fixes, so they don't appear to be vulnerable. Of course, obviously a little bit hard to tell what's being backported or not. Double check that there are no Apache updates for your particular Linux distribution, but so far I haven't really seen that affect any particular Linux distribution. Well, and that's it for today, so thanks for listening and specifically thanks for anybody who is like sending information about what you would like to hear more about or less about for that matter. It's always a little bit hard to tell what actually is actionable for you in these podcasts. So any feedback to that effect is highly welcome and talk to you again tomorrow. Bye.
