Hard to believe that. If you can grok the logs you probably know how and why the hack works. Plus they're not too informative, for example, few of them show the version of an application under attack, and a good chunk of the time you will see a line like:

  ~ $./domagic
  ~ #

Where `domagic` is published script.

There are good texts to read for security, and imo, lamer logs are not exactly at the top of that list. Read the public disclosures, advisories, PoC code; not the private gloating of hackers :-)
