Phishing Email Decoding Tools

PowerShell Script for Azure AD Synchronization Management

This PowerShell script performs the following actions:

1. It retrieves the Windows identity and security principal of the current user account.
2. It then retrieves the security principal for the Administrator role.
3. It checks if the current user is running as an administrator. If the user is not running as an administrator, the script relaunches itself as an elevated process.
4. If the user is running as an administrator, the script displays a menu with three options: “Delta Sync”, “Full Sync”, and “Exit”. The user is prompted to select an option by entering the corresponding number.
5. Based on the user’s selection, the script runs the appropriate command using the Start-ADSyncSyncCycle cmdlet with either the Delta or Initial policy type. If the user selects “Exit”, the script exits.
6. Finally, the script displays a message indicating that it is running and to check the “miisclient” to confirm. It then pauses for 10 seconds using the Start-Sleep cmdlet.

$myWindowsID = [System.Security.Principal.WindowsIdentity]::GetCurrent()
$myWindowsPrincipal = New-Object System.Security.Principal.WindowsPrincipal($myWindowsID)

UVa Online Judge Challenge "10110"

“There is man named ”mabu” for switching on-off light in our University. He switches on-off the lights in a corridor. Every bulb has its own toggle switch. That is, if it is pressed then the bulb turns on. Another press will turn it off. To save power consumption (or may be he is mad or something else) he does a peculiar thing. If in a corridor there is n bulbs, he walks along the corridor back and forth n times and in i-th walk he toggles only the switches whose serial is divisable by i. He does not press any switch when coming back to his initial position. A i-th walk is defined as going down the corridor (while doing the peculiar thing) and coming back again. Now you have to determine what is the final condition of the last bulb. Is it on or off?”

Given two numerical values your job is just to find out the relationship between them that is (i) First one is greater than the second (ii) First one is less than the second or (iii) First and second one is equal.”

Kattis Challenge "Line Them Up"

“An eccentric coach asks players on the team to line up alphabetically at the start of practice. The coach does not tell the players whether they need to line up in increasing or decreasing order, so they guess. If they guess wrong, the coach makes them run laps before practice. Given a list of names, you are to determine if the list is in increasing alphabetical order, decreasing alphabetical order or neither.”

Kattis Challenge "Server"
