What SIEM Data Sources Should You Integrate into Your Platform?

What SIEM Data Sources Should You Integrate into Your Platform?

In a perfect world, there would not be any need to mull over what data sources to integrate into an organization’s security information and event management (SIEM) solution. All kinds of data that can be used and abused by threat actors should be added. After all, attacks can hide behind seemingly innocuous logs.

But in reality, each data source comes at an additional cost since most SIEM solution providers typically charge per gigabyte. Thus, organizations have to strike a balance between budget constraints and security. However, one should not necessarily suffer for the sake of the other. But that requires careful strategizing in terms of what data sources to integrate into SIEM solutions.

This post takes a deep dive into SIEM data sources to help organizations understand the following:

  • What SIEM data sources are
  • Factors to consider when choosing SIEM data sources to feed to solutions
  • Potential data sources to integrate into SIEM solutions

Typosquatting Feed data for a DNS firewall

There is a tremendous number of domain names registered daily which resemble legitimate domains of brands or organizations, or whose names imply being related to a known service or product. Domains suggesting to be a “support” or “account-verification” or “support page” are also common for containing such strings. Initially, many of these are parked and some become used in malicious activities such as being sold at an inflated price to the legitimate owner, being used as botnet Command & Control servers, or in phishing campaigns to host fake pages to have the victim's sensitive data typed in and sent to the miscreants. 

Subdomain Finder Tools and Data Sources: Top 4 Cybersecurity Applications

Subdomain Finder Tools and Data Sources: Top 4 Cybersecurity Applications

Subdomains are useful as they help domain owners organize their websites. They identify specific pages on a company’s site, guiding customers and internal and external users to where they will find the information they need or product they wish to buy.

But while using subdomains indeed has advantages, it has disadvantages as well. Cybercriminals can use them for malicious campaigns that rely on subdomain takeovers, among other cyberattacks. Threat actors can also create subdomains and hide them under what seems to be totally legitimate domains to evade detection.

Subdomain-related threats are addressable, at least to some extent, with the help of a subdomain finder that enumerates the subdomains of a particular domain. This post explains how to go about it.

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

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.
