Network intrusion happens often enough that they almost certainly weren't after you personally. It's like email spam -- attackers probe thousands of systems hoping to find one easy catch. Did you ask your ISP how many other modems were under attack? For an ISP to even admit that their modems are being attacked hints at a large problem.

When did you lose your LastPass passwords? LastPass has cleared and deactivated accounts by the million to deal with their own intrusion attempts. Once again, probably not personal.

Had HexChat needed to install any updates after not using it for months? Had you installed it from scratch after the big computer-bleach? Once again, probably not personal, just a default setting.

In short, I don't think you're crazy -- I think you have an unclear idea how computer software and computer networking works. These events have very little in common, unclear motivation (why would a hacker want to rename your IRC networks?), and very different methods(random issues in your local computer, vs malicious hacking of a well-known password service, vs intrusion on your ISP's WAN, etc...), too many for me to assume they're all from the same person or have you in particular in mind. Reformatting your computer because someone attacked your modem is akin to burning down your house because someone looked in your window, anyway.

NAME

       dialups - list of terminal devices requiring a dial-up password

SYNOPSIS

       /etc/dialups

DESCRIPTION

       dialups	is  an	ASCII file which contains a list of terminal devices  that require a dial-up password. A dial-up password is an additional
       password required of users who access the computer through a modem or dial-up port.  The correct password must be entered before  the  user
       is granted access to the computer. The set of ports that require a dial-up password are	listed in the dialups file.

       Each entry in the dialups file is a single line of the form:

	      terminal-device

       where

       terminal-device	       The  full  path	name  of the terminal device that will require a dial-up password for users accessing the computer
			       through a modem or dial-up port.

       The dialups file should be owned by the root user and the root group.  The file should have read and write permissions for the owner (root)
       only.

EXAMPLES

       Example 1: A sample dialups file.

       Here is a sample dialups file:

       /dev/term/a
       /dev/term/b
       /dev/term/c

FILES

       /etc/d_passwd	       dial-up password file

       /etc/dialups	       list of dial-up ports requiring dial-up passwords
