Introduction  According to Forbes, more than 300 billion emails are sent daily, of which 90% of spam and malware and just one click on any of these emails can lead to data breaches and ransomware attacks. To avoid these clients and email services, fil...

The POODLE vulnerability, which stands for Padding Oracle On Downgraded Legacy Encryption, is a vulnerability in the SSL 3.0 protocol that allows an attacker to exploit the way in which the protocol handles padding to extract plaintext secrets from encrypted c...

The BREACH (Browser Reconnaissance and Exfiltration via Adaptive Compression of Hypertext) attack is a specific vulnerability targeting HTTP responses compressed using gzip or DEFLATE and encrypted via SSL/TLS. Fixing an SSL BREACH vulnerability requires a co...

Introduction Lazarus, also known as Hidden Cobra or Zinc, is a North Korean state-sponsored hacking group that has been active since 2009. The group is one of the world’s most active threat actors and has been behind large-scale cyber-espionage and ransomwa...

The Akira Ransomware Gang has quickly become a big threat to businesses and organizations, showing a high level of skill and harmful intentions. This article digs into who they are, where they target, what security holes they exploit, which industries they go ...

The RC4 SSL vulnerability refers to security weaknesses in the RC4 stream cipher when it is used in SSL/TLS protocols for encrypting web traffic. RC4 (Rivest Cipher 4) was once widely used due to its simplicity and speed, but over time, several vulnerabilities...

The Logjam vulnerability is a security flaw in the TLS protocol that allows attackers to weaken the encryption of HTTPS connections by forcing them to use weak, export-grade cryptography. It specifically targets the Diffie-Hellman key exchange process, exploit...

The TLS_FALLBACK_SCSV vulnerability addresses a specific issue in SSL/TLS protocols where a client and server could be forced to use a less secure version of the protocol through a downgrade attack. This security mechanism prevents such attacks by allowing the...

Lucky 13 vulnerability is a timing side-channel flaw in the TLS protocol affecting Cipher Block Chaining (CBC) mode ciphers. In this guide, we'll walk through the necessary steps to mitigate this vulnerability and reinforce the security of your network communi...

The BEAST (Browser Exploit Against SSL/TLS) vulnerability is an attack on SSL/TLS 1.0. The vulnerability takes advantage of the way in which blocks of data are encrypted under a specific type of encryption algorithm within the SSL protocol .To mitigate the BEA...

The "SWEET32" vulnerability is an attack on older block cipher encryption schemes that use a 64-bit block size. These ciphers are susceptible to collision attacks when a significant amount of data is transmitted under the same encryption key. In the context of...

Domain-based Message Authentication, Reporting, and Conformance (DMARC) is an email authentication protocol that is designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing. The purpose an...

The Sender Policy Framework (SPF) is an email authentication method designed to detect forging sender addresses during the delivery of the email. SPF allows the receiving mail server to check during mail delivery that a mail claiming to come from a specific do...

Overview Attack surface management is a critical aspect of cybersecurity that involves identifying, analyzing, and managing an organization's external-facing digital assets. A key component of this process is attack surface IP discovery, which includes scanni...

Overview During attack surface IP discovery, identifying open ports is a critical aspect of understanding an organization's potential vulnerabilities. Open ports, regardless of the specific service they're associated with, can present various risks if not pro...

Overview Effective remediation of risks associated with IP discovery and open ports is crucial for maintaining a secure attack surface. This document outlines strategies to address vulnerabilities identified during IP asset scanning and port discovery process...

What is IP Blacklisting? IP blacklisting is a security practice where specific IP addresses are blocked from accessing a network, website, or other internet services due to suspicious or malicious activity. When an IP address is blacklisted, it's added to a l...

Overview IP blacklisting occurs when an IP address is added to a blocklist due to suspicious or malicious activity. This can severely impact an organization's ability to communicate, send emails, or provide services. Understanding and addressing IP blacklisti...

What is Passive Vulnerability Assessment? Passive vulnerability assessment is a non-intrusive method of identifying potential security weaknesses in an organization's digital assets without actively engaging with the systems or networks. This approach gathers...

Passive vulnerability assessment is a crucial component of attack surface management. It allows for the identification of potential security weaknesses without actively engaging with the target systems. This knowledge base article focuses on three primary area...
