default passwords
About this tag
Default passwords are factory-set credentials shipped with embedded systems, appliances, and devices. The content on this tag covers the security risks of leaving default passwords unchanged, particularly for internet-connected systems. Discussions include vulnerabilities in medical devices like the Medtronic MyCareLink Patient Monitor and industrial recorders from Yokogawa, as well as the role of default passwords in botnets such as Mirai, which exploit IoT devices to launch DDoS attacks. A dedicated advisory (TA13-175A) explains how attackers easily identify systems using shared default passwords and emphasizes the importance of changing them. A user thread also addresses a Windows 7 password lockout, questioning whether a default password exists. Overall, the tag highlights the critical need to replace default passwords to protect systems from unauthorized access and cyber threats.
