In two words: don't worry. Unless you are being specifically targetted (in which case anyone who cares is likely to have your IP address already, or not need it, depending on the mode of attack), someone having seen an IP address is a curiosity at most. More to the point, the vast majority of "bad stuff" on the Internet is non-targetted; automated software ...
Is this a hacking attempt? Yes. And if so, how does the hacker (human or bot) immediately know where my server is and when it came online? You've hit the nail on the head, you're online. Just the act of being online exposes you to being scanned for vulnerabilities. They don't know you or that you put up a server. They do know the address ranges being ...

In short, the "35 passes" assumed older encoding techniques and lower data densities. It also assumed you had no idea how the drive was encoded. Each pass used a method specific to a drive ...
This feature, which switches to Protected View when handling older file formats, is called File Block. According to Microsoft: The code used to open and save the older formats have vulnerabilities that hackers can exploit. So they are security risks that should be avoided, if possible. See ...
The password isn't sent in plain text, but the old-style password scheme you're using has known issues that make it relatively easy to crack. See http://dev.mysql.com/doc/internals/en/authentication-method.html, and the related question http://stackoverflow.com/questions/11192689/how-secure-is-authentication-in-mysql-protocol.
If you are interested in a system which you believe might be compromised, run "Rootkit" and use "Tripwire" to check the integrity of the filesystem. Also would advise you to harden sudo privileges, like you don't need all users to have access all root commands rather give access to specific commands through SUDO.
There is no real protection. Password protected access to sudo harks back to an era before complex shell environments with commands executed by shims. Once the password has been submitted, there's a window of opportunity in which a shim can execute commands via sudo, without any notification, and with full system control. If I was intent on access, I'd ...
