This week started off big with the Panama Papers, the largest leak in history. The still-unfolding story uncovered a complex web of global tax evasion perpetuated by world leaders and their friends. Breaking the Panama Papers news required massive coordination: Over 100 journalists used a constellation of encryption tools and methods to help the whistleblower behind the leaks safely deliver 2.6 terabytes of documents.

Turkey had its own data spill this week as well, when an unnamed hacker posted the personal information of 50 million Turkish citizens extracted from poorly secured government servers. In other news, Kate Moussouris, the strategist behind the Department of Defense's and Microsoft's bug bounty programs, is branching out as an independent consultant.
