I am looking for a reliable source to download RE tools such as:
but it seems all the links in google are not safe, where can I buy or download it from a reliable not malwared source. Can I trust http://www.woodmann.com/ ?
Tools archived on http://www.woodmann.com/ should be safe.
I've personally met and trust most of the people who run the site (Woodmann, dELTA, etc.), and can vouch for their integrity.
There is also the option of tuts4you. They have an extensive download page there.
There is also http://www.openrce.org/downloads/ Though it does not have specific tools you are looking for, it has lots of plugins for IDA and OllyDbg. It is trustworthy source as well.
