Dark Caracal: Undisclosed Targeted Attack IoCs Can Pose Risks

Targeted attacks are known as some of the most destructive cyber attacks in that they zoom in on organizations that either provide critical services or have massive user bases.

A Look Into Tor Nodes’ Locations and ISPs with IP Intelligence

The Tor Project has been synonymous with the Deep Web, as it is a primary method by which users can access hidden portions of the Internet. Besides traffic encryption, an additional feature that gives Tor users anonymity is that their network traffic passes through several nodes, making the real source unidentifiable.

Attack Surface Analysis: Most Blacklisted IP Addresses Scrutinized

The attack surface of every Internet user gets wider every day, but it doesn't mean there's nothing that can be done about it. For one, analyzing possible attack vectors, such as suspicious or malicious domain names and IP addresses, can help with attack surface management.

Enriching IP Blacklists Using a Reverse IP/DNS Database

Every organization faces two kinds of cyber threats daily - "known" and "unknown" ones. Known threats are those that security experts have discovered, often published in blogs and major news outfits with accompanying indicators of compromise (IoCs). Unknown threats, meanwhile, are those that remain hidden to victims and researchers. IoCs for these have yet to be identified and disclosed.

Not All VPN Users Are Worth Trusting, a Lesson for Cloud Service Providers

Virtual private networks (VPNs) are widespread; about a third of the Internet population uses them worldwide. Their primary reason? VPN usage touts more secure browsing.

Gathering Context Around Emotet, Trickbot, and Dridex C&C Servers with Bulk IP Geolocation

Dridex, Trickbot, and Emotet are banking Trojans that have enabled cybercrime groups to steal hundreds of millions of dollars from their victims. These malware have evolved over the years, and just recently, Emotet was seen using stolen attachments to make their spam emails more credible.

Augmenting Digital Risk Protection with Threat Intelligence Sources

The world continues to produce and consume digital content at an increasingly fast pace across channels - making risk exposure continuously greater in the process. To tackle this problem, digital risk protection allows organizations to address digital risk factors and monitor and reduce their attack surface.

Everything You Need to Know About IPv4 vs. IPv6

The "IP" in IPv4 and IPv6 stands for Internet Protocol, which is a set of rules that determine how devices transmit data packets across the Internet. Internet Protocol also assigns a unique address to each device on the web. These addresses ensure data packets are routed to the correct device.

The Benefits and Risks of Leasing IPv4 Space

With address prices rising, the reasons you may want to become a lessor are clear: extended predictable revenue. Leasing creates an opportunity to monetize IP addresses and sell an IP block for a higher price in the future versus in the current market -- it allows the lessor to keep the IPv4 block in case of future need.

IP Blacklist and Blacklist Removal

Everyone hates spam. Even worse is malware - something that infects your computer and sends spam out to you and others or tries to hack into systems. In response to these problems, many people began to maintain lists recording who generates spam and malware.
