Found this little gem on the net just waiting to be data mined:
Welcome to the Directory of Open Access Journals. This service covers free, full text, quality controlled scientific and scholarly journals. We aim to cover all subjects and languages. There are now 2420 journals in the directory. Currently 709 journals are searchable at article level. As of today 118172 articles are included in the DOAJ service.
There are several papers on computer science as well as engineering, all of which could contain information valuable to a hacker (depending on what you are looking for).
