Wassenaar rules require export licenses for anything that could be considered “intrusion software”—but not in US, yet.

If your work involves exploiting vulnerabilities in software, congratulations—you’re potentially an arms merchant in the eyes of many governments. Your knowledge about how to hack could be classified as a munition.

A United States delegation yesterday failed to convince all of the members of the Wassenaar Arrangement—a 41-country compact that sets guidelines for restricting exports of conventional weapons and “dual use goods”—to modify rules that would place export restrictions on technologies and data related to computer system exploits.
