NSA’s use of software flaws to hack foreign targets posed risks to cybersecurity

To penetrate the computers of foreign targets, the National Security Agency relies on software flaws that have gone undetected in the pipes of the Internet. For years, security experts have pressed the agency to disclose these bugs so they can be fixed, but the agency hackers have often been reluctant. Now with the mysterious release of a cache of NSA hacking tools over the weekend, the agency has lost an offensive advantage, experts say, and potentially placed at risk the security of countless large companies and government agencies worldwide. Several of the tools exploited flaws in commercial firewalls that remain unpatched, and they are out on the Internet for all to see. Anyone from a basement hacker to a sophisticated foreign spy agency has access to them now, and until the flaws are fixed, many computer systems may be in jeopardy.
