ProPrivacy Open Data Project: Mapping Malicious Coronavirus Domains Using WHOIS Data

The COVID-19 pandemic has driven many people to do almost everything within the confines of their homes. Nearly exclusive reliance on digital means to work, study, shop, and communicate amid uncertainty opened many avenues for cybercrime to take place—notably through the use of coronavirus-related domain names.

To demonstrate this trend, ProPrivacy has partnered with WhoisXML API and VirusTotal to investigate the extent to which cybercriminals are weaponizing the Domain Name System (DNS) in an open data project called “COVID-19 Malicious Domain Research Hub.”

NormShield Success Story: Leveling Up Third-Party Risk Assessment with Domain & IP Intelligence

WhoisXML API is proud to announce its partnership with cybersecurity solution provider NormShield. NormShield enables enterprises to evaluate their external cyber risk posture by letting them conduct non-intrusive third-party risk assessments. NormShield’s growing client base operates in various industries, among which are financial services, healthcare, manufacturing, retail, and tech in general.

The results of third-party risk assessments powered by NormShield come in the form of intuitive scorecards that immediately tell enterprise users what their most salient cyber risks are. The scorecards also contain recommendations on how to deal with each risk based on its priority level.

NormShield relies on comprehensive and accurate domain, subdomain, and IP address data to conduct thorough risk evaluation of its clients’ suppliers, subsidiaries, and other stakeholders. The company has partnered with us to integrate the IP Neblocks WHOIS Database Feed and Whois Database Feed into its processes — now monitoring more than 1.2 billion domains, 7 billion WHOIS records across 2,864 top-level domains (TLDs), and 9.1 million IP netblocks.

Here is more about the challenges our products have helped to deal with and the exciting details of this fruitful collaboration.

Cybercrime After the Sunrise: are the new gTLDs nests of abuse?

ICANN's new gTLD program, initiated in 2007 and started in 2013, resulted in the appearance of more than a thousand generic top-level domains, confirming the significant business demand for these. Some are related to regions or locations (like .amsterdam), some to communities (e.g. .pharmacy) or brands, and many of them are just words having a marketing value. But apart from the opportunities for customers, unfortunately they also pave new ways for cybercriminals for abusing the domain name system. Even though ICANN has built safeguards into the process to mitigate this risk, it has become a widely accepted surmise that new gTLDs are frequently the base camps of spamming, phishing, botnets and other forms of abuse. Is it really the case?

DNS Forensics Using the Big Data Extension
of IBM’s QRadar Security Intelligence Platform

The basis of IBM’s key security solutions is the QRadar Security Intelligence Platform, a security information and event management system (SIEM). It is a unified platform covering many security-related tasks and incorporating a broad spectrum of solutions including the use of X-Force Threat Intelligence, IBM’s cloud-based threat intelligence platform.

The big data extension of QRadar can be used to do DNS forensics in order to identify risky domains, risky users, and risky IP addresses, and feed this information back to QRadar in order to define new protection rules...

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...

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...

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...

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...

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...

Christine Bejerasco
Senior Analyst at F-Secure Labs
We found certain nameservers that were always used for a phishing campaign, having those in our rules enabled us to catch phishing sites before they affected our user base. WhoisXML API is a responsive and reliable provider of domain intelligence. Whenever there are issues, they are quick to respond and resolve them. Working with them is smooth and straightforward.
Rich Sutton
VP of Engineering at Proofpoint
The Proofpoint Digital Risk team uses Whois data as an input to heuristic detection of suspicious and/or malicious domains. At Proofpoint, we're in the business of protecting our customers from threats across web, mobile, email and social. WhoisXML API’s domain intelligence allows us to quickly integrate Whois lookups into our security heuristics and algorithms without having to worry about hosting services, staging and merging data, and the complicated task of normalization.
