In today’s digital-first world, software supply chains have become the backbone of innovation. Developers rely on open-source repositories like npm (Node Package Manager) to speed up application development, integrate libraries, and avoid reinventing the wheel. But with this convenience comes significant risk: malicious actors are increasingly exploiting this trust, embedding malware in seemingly legitimate packages to steal sensitive data.

In cybersecurity, the most dangerous attacks are not always the ones that arrive with flashy ransomware notes or obvious malware signatures. Increasingly, the most damaging threats are the ones that look entirely ordinary. They slip under the radar, disguised as everyday processes or, even worse, cloaked in the trust we place in our own tools.
A new and concerning trend highlights this shift: attackers are weaponizing Velociraptor, an open-source forensic and incident response tool, to infiltrate networks and exfiltrate data.

In today’s hyper-connected world, identity is no longer just an administrative concern—it is the new perimeter of cybersecurity. The recent discovery of Storm-0501, a sophisticated phishing campaign targeting Microsoft Entra ID (formerly Azure Active Directory), has highlighted just how vulnerable organizations can be when attackers bypass traditional defenses and focus directly on identity systems.

When you connect to a public Wi-Fi network, what’s the first thing you see?
Usually, a captive portal that login or “Agree to Terms & Conditions” page you click before getting access. For most people, it’s a routine step. But what if that portal wasn’t a harmless gateway, but instead a weaponized tool used by cybercriminals to infect your device?
That’s exactly what’s happening in a sophisticated cyber campaign launched by UNC6384, a threat actor now under global watch. By exploiting captive portals, UNC6384 is distributing the notorious PlugX malware, a remote access trojan capable of data theft, persistence, and further compromise.

In today’s fast-moving digital world, software supply chains have become both a cornerstone of innovation and a prime target for attackers. A recent discovery reported by The Hacker News highlights a particularly troubling case: a malicious Go module named “golang.org/x/ssh” was found imitating the legitimate SSH library to deliver backdoor access.

In the ever-evolving world of cybersecurity, every year introduces new attack methods, more sophisticated adversaries, and more critical vulnerabilities. But among the most concerning trends emerging today are pre-authentication exploit chains—a class of attacks that can allow cybercriminals to completely bypass login mechanisms and gain unauthorized access to critical systems.

Did you know that unpatched vulnerabilities in IT management tools can serve as a direct doorway for cybercriminals—leading to ransomware outbreaks, massive data breaches, and even nationwide supply chain compromises? The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has just added two critical flaws in N-able N-central to its Known Exploited Vulnerabilities (KEV) catalog. This is not a routine security advisory—these are flaws that attackers are actively weaponizing. If your business uses N-central, the clock to patch is already ticking.

Did you know a single hidden backdoor in one widely used open-source tool could compromise millions of systems worldwide?
That’s exactly what happened with XZ Utils—a seemingly harmless compression utility that ships with multiple Linux distributions.
In late March 2024, security researchers discovered that the latest versions of XZ Utils had been secretly modified to include a remote access backdoor. This wasn’t just a routine vulnerability—it was a carefully planned software supply chain attack.

Did you know that more than 2 million organizations worldwide rely on TETRA (Terrestrial Trunked Radio) systems for their “secure” voice and data communications? These systems have been trusted for decades by law enforcement, military, transportation, utilities, and emergency services.
But a recent, bombshell discovery has revealed critical encryption flaws in TETRA—flaws that have quietly existed for decades—leaving these organizations dangerously exposed to cyberattacks.
For sectors where secure communication is the backbone of operations, this is more than a technical issue—it’s a national security risk.

Did you know that over 60% of malware infections in 2024 originated from malicious ads?
That’s a staggering statistic, and it underscores a reality many businesses overlook — the very ad networks we use to promote products and services can also be hijacked to deliver malicious payloads.
