WHOIS Data for Vulnerability Notifications

One of the cornerstones of cybersecurity is threat intelligence sharing. Maintenance of our IT systems' security and their protection against malicious activity require up-to-date knowledge of the entire field. There are significant efforts to assist experts in this activity, including those of market leaders such as IBM X-Force Exchange.

Due to the decentralized architecture of the Internet, however, the collaboration of the actors as well as voluntary campaigns in order to detect vulnerabilities are also of utmost importance. If, however, the owners of the affected systems cannot be notified, these efforts can hardly achieve their positive goal. And in this notification process, WHOIS data have their use...

The WPAD Name Collision Vulnerability in the New gTLD Era: a Threat Crying for Urgent Solution

Sometimes certain comfortable and seemingly innocent protocols can introduce significant security risks, especially when the system's environment changes.

The WPAD (Web Proxy Autodiscovery) protocol is prevalently used to configure the web proxy settings of end systems such as desktops and other devices belonging to an administrative domain, e.g. a corporate network. The benefit of this solution is that system administrators can deploy local web proxy settings essentially without any user interaction. Due to a very progressive change in the domain registration policies, the otherwise very useful WPAD protocol has introduced the possibility of a new and very dangerous man-in-the-middle attack...
