Shadow IT refers to the use of applications, devices, or services within an organization without approval from the IT department. Employees often download apps or sign up for cloud services on their own to get work done faster. While this may seem harmless, Shadow IT bypasses official security measures and can expose sensitive business data.
Artificial intelligence has brought us incredible tools, from voice assistants to realistic image generators.

What started as a novelty on the internet has quickly grown into a serious cybersecurity and societal threat.
When most people hear the termdark web, they imagine a shadowy corner of the internet filled with hackers and illicit marketplaces. While that perception is not entirely wrong, the reality is more complex and far more relevant to businesses than many realize.
A critical vulnerability in the HTTP/2 protocol, known as MadeYouReset (CVE-2025-8671), has been discovered by researchers at Tel Aviv University. This flaw allows attackers to launch denial-of-service (DDoS) attacks without violating the protocol specifications. Although no live attacks exploiting this vulnerability have been observed, its potential to cause significant disruptions is concerning.
Organizations across multiple sectors are grappling with attacks from theCrypto24 ransomware group, known for their sophisticated stealth techniques and EDR evasion. First observed in September 2024, Crypto24 has been leveraging legitimate Windows tools combined with custom malware to bypass security defenses and escalate privileges.Trend MicroandBleepingComputerconfirm that large-scale campaigns have already targeted financial, healthcare, and logistics networks.
ADistributed Denial of Service (DDoS) attackis a malicious attempt to disrupt the normal traffic of a targeted server, service, or network by overwhelming it with a flood of traffic from multiple sources. Unlike a basic Denial of Service (DoS) attack, which comes from a single source, DDoS attacks leveragebotnets— networks of compromised devices — to amplify their impact and make them harder to stop.
Domain impersonation is a cyberattack where criminals create a domain name that looks almost identical to your legitimate business domain. For example, if your domain iscyberdefence.com, an attacker might registercyberdefenee.comorcyber-defence.com.
Cybercrime continues to evolve, and one of the most dangerous threats to businesses today iswhale phishing, also known aswhaling attacks. While most people are familiar with phishing emails targeting everyday users, whaling is far more sophisticated and far more damaging. In this article, we’ll break down what whale phishing is, how it differs from regular phishing, who is most vulnerable, and the severe consequences of falling victim to these attacks.
In today’s increasingly digital world, cyber threats continue to evolve, becoming more sophisticated and persistent. Organizations of all sizes are prime targets, making it crucial to adopt a proactive and robust security strategy. This strategy starts with establishing and maintaining astrong security posture.
When most people think about cyber threats, they imagine a faceless hacker launching attacks from a remote location. But some of the most dangerous threats are already inside the organization—on the payroll, behind a desk, and logged into your systems.
An active campaign, identified asRedDirection, has compromised over2.3 million usersthrough Chrome and Edge browser extensions.
In recent years, cyber-crime has evolved beyond isolated hackers working alone in the shadows. Today, much of it operates like a business — with customer support, subscription models, and even marketing. One of the clearest examples of this shift isMalware as a Service (MaaS).
