Responsible Disclosure

“The National Cyber Security Centre under the Ministry of National Defence (NCSC) applauds the actions of UAB Critical Security experts after discovering the bug. Responsible disclosure practices are still in the process, and this example demonstrates how the public and the private sector are able to cooperate in practice on cyber security. Submission of the information has given us the time to carry out additional investigation and inform the affected entities who then took action ahead of making the information public. We hope that making the issue of factory passwords in Wi-Fi networks public will help users to take a better care of their security” Director of the NCSC Dr. Rytis Rainys said.
