If you are a tech savvy person – you probably know how phishing works. However, this time attackers tried to use optical illusion to trap people into a new phishing scam targeting the GMail users. Here’s how it looks like:
Scammers attach an image which looks like it is an attachment. When you click on it – it takes you to the scammers destination – to the phishing link. And if you ignore the login URL – you are DONE!!
The phishing login page has been tricked as well to look like it is from Google. So even the most savviest person may fall for the trick. Here is how the phishing page URL will look like:

YOU WANT TO KNOW THE WINDOWS SERIAL KEY – WHICH WAS USED TO ACTIVATE YOUR WINDOWS.
- You may be planning to re-install the windows. You may have lost the key.
- You may be selling your computer and buying a new one – but want to retain your copy of windows.
No Worries. You can retrieve your key from the computer. In this case you’ll need a running windows to get the key.
Copy and paste the following into a Notepad, save the text file and rename the file to “productkey.vbs”:
Set WshShell = CreateObject("WScript.Shell")
MsgBox ConvertToKey(WshShell.RegRead("HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId"))
Const KeyOffset = 52
i = 28
Chars = "BCDFGHJKMPQRTVWXY2346789"
Cur = 0
x = 14
Cur = Cur * 256
Cur = Key(x + KeyOffset) + Cur
Key(x + KeyOffset) = (Cur \ 24) And 255
Cur = Cur Mod 24
x = x -1
Loop While x >= 0
i = i -1
KeyOutput = Mid(Chars, Cur + 1, 1) & KeyOutput
If (((29 - i) Mod 6) = 0) And (i <> -1) Then
i = i -1
KeyOutput = "-" & KeyOutput
Loop While i >= 0
ConvertToKey = KeyOutput
Now run the file “productkey.vbs”. You should see something like this:
Note it down and save it somewhere. Good luck.

Internet connected Linux servers are always vulnerable to exploitation by the hackers/intruders. One of their common attack is through SSH. By default SSH servers are configured to listen to port 22 for SSH connection. Changing the port to something else will definitely add an additional measure in securing the server.
How to Change Default SSH port 22 to something else:
- Connect to your server via SSH (your ssh port is still 22) as the root user.
- Run this command: # vi /etc/ssh/sshd_config
- Find out this line: # port 22
- Delete the hash “#” sign from the beginning of the line and change the port to something else. Note down this new port very carefully. You’ll need to use this port for the SSH connection from the next login.
- Save the file and exit.
- Restart the SSH service by executing this command: # service sshd restart
Now disconnect and try reconnecting with the new SSH port. Make sure you memorize the new port number or note it down somewhere.
