Betreff: [suse-security] cracked system?
Hi!
I am "Newbie", using SuSE 9.1.
DSL from T-Online. Xmain Evolution 1.4.6.
Last weeks, I am experiencing mails from unknown people to my email-adresses. Sometimes two or three mails within a few seconds. These are accounts with T-Online, Ginko, Web.de. I looks as "they" knew all may emailadresses.
I'm asking myself, if there is a general(?) procedure how to get rid off these potential parasites?
These scheme should follow these steps:
- analyse
- evaluation
- proof of solution
QUESTIONS:
1.) Is there a (simple?) way to deciffer...
1.a) who is doing what on my system,
1.b) how do they come there
2.) Does anybody know, how I can "clean" my system, in ideal case without changing Email-Adresses (printed an business cards).
Thereby, I mean: how can I reject unwanted mail?
A simple "How-To", Tutorial or so preferable.
3.) For future, I like to prevent from re-establishing those trash-mails
again: how can I prevent unknown people from using "my adresse"?
3.a) My fear is, that my emails addresses "travel" uncontrolled. Is there a way to control? (I know, this seems to be naiv)
3.b) How can I reject unwanted mail?
3.c) Do I need to create positive liste following the thought: who may send me an email (filtering)?
A simple "How-To", Tutorial or so preferable for the above mentioned questions.
Thank you for all useful hints!
(P.S.: as I said: I am newbie)
