SS7 Attacks - The Exploit That Can Intercept Your Calls and Texts

-
Image
  In an era where cybersecurity threats are constantly evolving, one of the lesser-known but dangerous vulnerabilities in the global telecom infrastructure involves a protocol called Signaling System 7 (SS7) . This system, crucial to how mobile networks communicate with each other, is vulnerable to attacks that allow hackers to intercept calls, read text messages, and track users’ locations. But what exactly is an SS7 attack, and why should you be concerned? Let’s dive into how this attack works and why it remains a significant threat today. What is SS7? SS7, or Signaling System 7, is a set of protocols used by telecommunication networks to exchange information necessary for setting up and routing phone calls, sending SMS messages, and enabling services like roaming between different networks. It acts as the backbone of global mobile communication, allowing different phone networks to communicate with each other efficiently. SS7 was designed in the 1970s, at a time when security was no

Why an Attacker Might Use tcpwrapped

-
Image
  Evasion : By restricting access to a service, the attacker could make it more difficult for security tools like Nmap to identify the type of service running on the port. The result is that the service appears as tcpwrapped , giving the impression that it is well-secured or inaccessible, when in reality, it may be a malicious service that is only available to authorized users (e.g., those coming from specific IP addresses or ranges). Concealing Malicious Services : The attacker could be running a backdoor, C2 (command and control) server, or other unauthorized service while making it look like an innocuous or inaccessible port. This would make it harder for security professionals to notice or investigate that service, as it may be assumed to be a legitimate, restricted system service. Limiting Exposure : By restricting access, the attacker can limit the pool of potential investigators or defenders who could probe the port for more information. Only users with the right IP address, cre

New Windows Security Flaw CVE-2024-38063

-
Image
A critical vulnerability, CVE-2024-38063, has been discovered in Microsoft's Windows operating system, specifically in the IPv6 TCP/IP stack. This flaw has a CVSS score of 9.8, indicating a high level of severity. It is a "zero-click" vulnerability, which means that an attacker could exploit it without any action from the user, making it extremely dangerous. Additionally, it is "wormable," so it can spread from one system to another automatically, potentially causing widespread damage. How the Vulnerability Works CVE-2024-38063 affects all Windows systems with the IPv6 protocol enabled. Attackers can exploit this flaw by sending specially crafted IPV6 packets to a target system, allowing them to execute remote code by using integer underflow to trigger a buffer overflow. This could lead to unauthorized complete control of the system. The vulnerability is particularly concerning for any Windows devices that are directly exposed to the internet. It's certainly

Understanding Critical Subdomains in a Website, What They Are and Why They Matter

-
Image
SubDormains In the complex architecture of a modern website, subdomains play a crucial role in organizing content, services, and functionalities. While these subdomains are essential for seamless operation, they can also become significant security risks if not managed properly. In this article, we’ll explore the critical subdomains of a website, their purposes, and the potential risks they pose if compromised. What Are Subdomains? Subdomains are extensions of a primary domain that allow website owners to create separate sections or branches under the same domain name. For example, in the URL `blog.example.com`, "blog" is a subdomain of the primary domain "example.com." Subdomains can be used to host different parts of a website, such as a blog, e-commerce store, or admin panel. Critical Subdomains and Their Purposes Understanding the purpose of each critical subdomain is essential for both web developers and security professionals. Below, we list some of the most c
