How to attribute blacklisted IPs to RIRs with IP WHOIS data

Analyzing IP addresses is a strategic battlefield in the fight against cybercrime. For instance, there are a number of blacklists and blocklists available, collected with various methodologies and updated dynamically to assist the implementation of IP-based threat risk mitigation measures. Such blacklists are also interesting from a research point of view as they facilitate the study of trends, structure, and dynamics of malicious IPs. 

Given a suspicious IP address or netblock, the ownership information is also of paramount importance as it contributes significantly to the knowledge of the infrastructure of potential opponents. This information can be obtained from direct WHOIS lookups. However, WHOIS services normally pose limitations on the amount and frequency of available queries. Alternatively, one can use WhoisXML APIs services. These range from a simple web form for IP WHOIS lookup through a RESTFul API through the possibility to download a comprehensive IPv4 Netblocks WHOIS database along with incremental updates. These facilitate IP WHOIS database queries, highly customized ones without limitations, and also enabling to search in historic data. 

In what follows we use an IP WHOIS database set up in MySQL to analyze an actual blocklist of IPs. Our focus is on studying the share of those networks which are administered by APNIC in the blacklist, in comparison to the other RIRs, and to gain an understanding of certain behaviors.

A Cyber Threat Intelligence Recap for COVID-19 in 2020

Much has been said about the COVID-19 pandemic. In many ways, it has changed the way we live, work, or simply interact with our relatives and friends. From the standpoint of cybersecurity, the pandemic also had a strong influence on how threat actors and cybercriminals created and executed all types of cyberattacks and phishing campaigns.

To illustrate, this post features a timeline of COVID-19-related cyber threats and some cyber threat intelligence found for each month of 2020.

Social Media Phishing: Expanding the List of IoCs for Recent Facebook Page Impersonation Attacks

A few months back, security researchers noticed a spike in the volume of social media phishing attacks. Cybercriminals had been impersonating the Facebook pages of various influential personalities proactively in hopes of luring their followers into parting with their account credentials. The social media campaign focused on the Facebook pages of influencers with tons of followers.

A researcher from security firm Trend Micro believed an average of three pages were being spoofed per day. The personalities targeted were from Taiwan, India, Australia, Canada, and the Philippines.

The attackers began by stealing the target pages’ administrative account credentials. Once done, they sent a malicious link to all of the page’s followers for the potential victims to give out their own account credentials. As a common practice among phishers, the cybercriminals mimicked the pages down to their profile photos. As of August last year, 120–180 fake Facebook pages believed to be part of the campaign were seen.

Website Categorization Explained - Complete Guide For Your Business

Great attention has been directed lately towards website categorization; a cybersecurity practice which has been around for a while, but it wasn’t until recent times that it started to be increasingly used in marketing and business.

Website categorization is, in essence, the act of putting websites related by their content and function into similar categories. With that in mind, sites like Amazon and Ebay are grouped as Ecommerce sites; CNN, BBC and the likes are classified as news sites; Twitter and Facebook are tagged as social media sites, while Reddit and Quora are Forums (Message Boards) and so on.

However, what some people might not realize is that website categorization is a totally different ball game from Search Engine Optimization and Alexa rankings. Each is different and should be approached in that light - and not be confused.

Company Marketing Intelligence from Subdomain DNS Records

Marketing intelligence refers to any information about a company’s market base. It not only reflects industry trends but also refers to any information about the organization’s target market, existing customers, and even competitors. In particular, 94% of companies invest in competitive intelligence, a significant part of marketing intelligence.

While there are several marketing intelligence sources in existence, one less tapped source is the Domain Name System (DNS). DNS records, such as mail exchange (MX) and TXT entries and subdomains, can help companies answer these questions:

• What external services do competitors or key industry players use?
• Are other industry players set to launch new products? What are these?
• Are there potential mergers and acquisitions (M&A’s)?

In this post, we demonstrated how Subdomain DNS Record lookup tools that glean data from a DNS database could help enrich marketing intelligence.

WHOIS running the Internet from May 25, 2018 onwards?

The virtual space of the Internet is a relevant scene of our everyday life. And the elements of reality and their virtual counterparts – friends with social media contacts, shops and web shops, companies and websites, etc. – are becoming more and more confusable. Albeit this must have been in principle already expected by the founding fathers and mothers of the Internet, in many respects the Internet has been developing not quite as they had envisaged.

For instance, it had been clear from the very beginning that there should be a link between Internet domains and the real-life people and entities responsible for them. In the beginning, the motivation was mainly technical, of course: if something went wrong on the network, the operators needed to know whom to contact. This demand gave birth to the WHOIS protocol, a standard way to learn who is responsible for a high-level Internet domain.
