In August 2025, the City of St. Paul suffered a significant cyberattack that disrupted municipal services and triggered a state of emergency. In a televised interview with KSTP News, Michael Cobb, Director of Engineering and Chief Information Security Officer at DriveSavers, shares expert commentary on the scope of the attack and the challenges of data recovery.
Cobb discusses the growing number of municipal ransomware incidents, the difficulty of recovering from encrypted or deleted data, and the technical complexity of restoring entire city networks.
Watch the full segment to hear Cobb’s expert perspective on the cyberattack’s impact and why recovery is never simple.
Michael Cobb, Director of Engineering and CISO at DriveSavers (Cobb):
We are absolutely seeing a very huge uptick of cities being hit with these type of attacks.
Richard Reef, KSTP News:
Michael Cobb’s company, DriveSavers, recovers data after cyber attacks. He says the hardest task is to not only make sure servers are secure, but also to recover data from hundreds of city computers.
Cobb:
That’s a, a very difficult thing, especially if the threat actor was able to either delete the data that’s necessary to run the function or encrypt it.

macOS Sequoia’s Macintosh screen saver is one of the strongest hits of nostalgia Apple has ever produced. If for some reason you haven’t seen it, Mr. Macintosh has you covered:
When this showed up last year, a little birdie told me that it was dynamically generated based on the user’s preferences, which explained why I couldn’t find it as a movie anywhere in the filesystem.
I’ve used it as my screen saver since then — set to Dark Gray — but I never made it around to digging into what makes it tick.
When looking for macOS Tahoe’s wallpapers, I was reminded of this project. I went digging through the SSD on my MacBook Pro, and my journey through Finder has yielded great fruit.
The screen saver is actually an Extension, residing at /System / Library / ExtensionKit / Extensions / WallpaperMacintoshExtension.appex
(spaces added for legibility).
Right-clicking to “Show Package Contents” unveils a treasure trove:
I’m not really a programmer, but I know enough to see how this works. There is code telling those images how to move and interact with each other through a set of .program files. If the user has Macintosh set as their wallpaper, the screen saver slides to a stop once they return to the Desktop.
Here you can see IconGarden.program, resaved as plain text. Here is its corresponding image:
Here we have System6ControlPanel.program as plain text, and its image:
Interestingly, a bunch of the .program files include the string “Macintosh 40th Anniversary,” which helps explain how this project came to be.
For preservation purposes, I figured I should export the Macintosh images at a larger resolution for easy sharing. You can snag a .zip of them here.
