DownloadUND-v1.0.0-Setup.exe(758kb,nullinstallation package, decompress to 2 files, undmaker.exeand undviewer.exe. Use undmaker.exe to open a 1.doc (26KB) file saved in Word97-Word2003-compatible format with the content of test, set some encryption, the password is 123, only three times. Click confirm to create a 1.und( 12 K), open it with UndViewer.exe, and display the Word content, which is a very white window. Right-click and suddenly disappear because it is blocked. Use the IE tool included with Spy4win to check out the source code.

After carefully studying the principle of encryption and decryption of the X-File lock, convert the Office file *. the mht format is encrypted and saved as the und format. The viewer is an exe embedded with a WEBBROWSER used to open the und format. Then we can find the cache location of mht on the disk.
Open FileMon and find the location where the file is saved: C: Windowsundat. Directly using the resource manager terminal will block the file undview.exe and cause the explorer to crash. The solution is to use iceswordto kill undviewer.exe and then slowly open this file *. mht appreciation ......
Okay, we completely cracked the poor X-File lock.
Ps, I didn't mean it ......
