            Dark Crawler, a Useful Tool to Assess Child Exploitation from Online Communities

            Child sexual offenders have always been quick to adapt technological advances, such as photography and film for the purposes of exploiting children. The move of child exploitation material (CEM) to the Internet has enabled them to form online communities which allow easier access to CEM, recruiting co offenders and business partners, as well as validating their deviant behavior amongst other offenders.

            Despite the established harm inherent within child exploitation imagery and distribution online, current attempts to limit such content have been largely unsuccessful.

            Dark Crawler is a tool used by search-engines to automatically navigate the Internet and collect information about each website and webpage which can be used to seek out specific content, such as child exploitation material ...

            Whois Data Opening up a New Avenue
            for the Measurement of Entrepreneurship

            Entrepreneurship is the central process through which economic growth and performance is fostered in a regional economy. Its evaluation is thus of paramount importance for policymakers and economists. However, the quantification of entrepreneurship, that is, introduction of measures to describe the attempts to start growth-oriented business, the likelihood of their success, the ability to raise venture capital, etc. is a challenging task due to the lack of globally available and accurate input data on e.g. business registration.

            In a recent working paper a new approach is proposed to overcome this issue by using WHOIS registration data. The approach is applied to companies in Oxford and Cambridge, UK as a demonstration, by using data purchased from WhoisXML API.

            Malicious URL Detection via Machine Learning

            Protection against malicious websites is an important task in cybersecurity. A common way of identifying such sites is the use of blacklists which contain a large set of URLs considered dangerous. There are various techniques for compiling such lists, and there is obviously a need for methods to verify if a suspicious site is really dangerous...

            Is a HTTPS Webpage as Secure as Expected?

            Encrypted communication on the Internet is most commonly realized by Secure Sockets Layer (SSL) and Transport Layer Security (TLS). Webpages communicating sensitive content, including Internet banking, webshops, etc. use the HTTPS protocol which is based on this. E-mail servers, when communicating with clients in a secure manner, use the relevant e-mail transfer protocols such as SMTP, IMAP or POP3 over SSL/TLS.

            In current practice web pages are often hosted at least in part by third-party hosting providers or content-delivery networks. Thus the hardware systems we communicate with belong to these third parties, which may host many other pages of completely different entities. And, in order to establish desired secure communications, these parties have to get hold of private keys of these entities. Currently, many providers overtake even the management of keys from their clients which gives rise to profound and possibly severe security implications...

            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...
