Suspender.dll

Filed under: My Software — Didier Stevens @ 16:12

When the suspender DLL is loaded inside a process, it will wait for 60 seconds and then suspend all the threads of the host process. If you want another delay, just change the name of the file by appending the number of seconds to sleep. For example, suspender10.dll will wait for 10 seconds before suspending the process.

To resume the process, you can use Process Explorer.

I’ve used this DLL to analyze malware and to disable some unwanted programs without killing them.

And from now on, I’ll try to release 32-bit and 64-bit versions of my tools.

Signed Spreadsheet with cmd.dll & regedit.dll

Filed under: Hacking,My Software — Didier Stevens @ 14:05

Remember my Excel with cmd.dll & regedit.dll?

Paul Craig has a signed version of my spreadsheet on his iKAT site. Download ikat3.zip and look for officekat.xls.

These signed macros are handy when you’re working in a restricted environment that requires Office macros to be signed.

LockIfNotHot

Filed under: Hardware — Didier Stevens @ 8:34

When Phidget came out with this new IR temperature sensor, a lightbulb went off. This sensor measures temperature without contact. Point it to the chair in front of your computer, and it will measure your body temperature. Or the temperature of your chair, if you’re not sitting in front of your computer.

And that’s the idea: I wrote a program that locks your Windows workstation when you leave your chair (e.g. when the temperature drops).

In this screenshot, LockIfNotHot is configured to lock the workstation when the temperature drops below 25°C during 3 seconds and there is no user input during 2 seconds.

Once the workstation is locked, you need to provide your Windows account password to unlock it.
