It correctly reflects events as detailed by the post. The post clearly assumes that "the FBI" originated the exploit code and has been using it to harvest visitor IP addresses. I believe "infiltrated" is a fine summarization for that.

I suppose it's possible that the founder had a change of heart two days prior to his arrest and started collecting everyone's IP and sending it to the FBI based on nothing but a sense of personal moral obligation, but it doesn't seem too likely, and it's irrelevant either way because again, the proposed title is an accurate description of the posted article, even if the posted article is an inaccurate depiction of Real Life(tm).
