EDIT: This is not what the group has done upon further scrutiny of the article. It's just their very first sentence makes it sound like they were intentionally introducing vulnerabilities in existing codebases to achieve a result.
I definitely can see that it should have been worded a bit better to make the reader aware that they had not contributed bad code but were finding existing vulnerabilities in software which is much better than where I went initially.
