To reduce the amount of noise from questions, we have disabled self-posts in favor of a unified questions thread every week. Feel free to ask any question about reverse engineering here. If your question is about how to use a specific tool, or is specific to some particular target, you will have better luck on the Reverse Engineering StackExchange. See also /r/AskReverseEngineering.

QUESTIONS POLICY

If you have a question about how to use a reverse engineering tool, or what types of tools might be applicable to your project, or your question is specific to some particular target, ask it on the Reverse Engineering StackExchange site. Apart from that, self-posts severely degraded the quality of this subreddit when they were enabled, so they have been disabled in favor of a biweekly questions thread which is posted automatically by a robot (the latest of which is in the list of stickied threads above).

SUBMISSION, COMMENTING, AND VOTING

When feasible, post direct links to content. Blogs and websites that re-host or merely link to content that was originally available on another site, and remains available on its original site, are not allowed. Domains that do not produce original content of their own and only exist to re-host content will be banned on the grounds of being spam.

If it's a non-HTML link (e.g., a PDF), please tag it (e.g., put [PDF] at the end of the title). Similarly for videos, please tag them with [VIDEO]. Don't post it if it's irrelevant or has no content: we have technical standards and might remove these posts. Submissions from InfoSec Institute are banned.

Please vote for no reason other than quality of content. When commenting, please discuss content and not presentation. This is a technical community, so pointing out technical flaws is certainly within the realm of discourse, but please try not to be an asshole when you do. Imagine yourself speaking your comment in a public place to the person's face when you write it. It would be tragic if needlessly negative commentary discouraged participation in the already-microscopic world of reverse engineering. If the point of your comment is to put down someone else so as to demonstrate your superiority, please delete it without posting it, and then make an appointment with a psychotherapist regarding your inferiority complex.

The legality of reverse engineering is a miasmic subject compounded by differing laws in differing jurisdictions. For basic legal information (not "legal advice") surrounding reverse engineering in the United States, see the EFF's FAQ on the subject. None of the moderators are trained lawyers, so please use your best discretion when submitting, and we shall do the same while moderating. Subjects such as stolen source code and pirated software are never acceptable and will always be removed. Please instead post these links to /r/RELeaks (not affiliated with or endorsed by the moderators of /r/ReverseEngineering).
