In January 2026, the GNU telnetd service from GNU InetUtils was found to be vulnerable to authentication-bypass by Simon Josefsson. Tracked as CVE-2026-24061, this flaw allows an attacker to establish a Telnet session without providing valid credentials, granting unauthorized access to the target system. The vulnerability exists all the way up to version 2.7-2 of the GNU telnetd service and, as indicated by Simon, looks like it was taken right out of the 90s.

Insider threats remain one of the most challenging security risks organizations face. Unlike external attackers who must breach perimeters, insiders already possess legitimate access to critical systems and data. They understand security controls, know where valuable assets reside, and can operate under the radar of traditional rule-based detection systems for extended periods.

Guest post by WatchGuard Tech All-Star, Michael Carter II At a glance: The trend is hard to ignore: most attackers do not “break in” anymore; they sign in using stolen or abused identities, not by bypassing a next-gen firewall, your EDR, or those fancy email and collaboration tool defenses. If an unauthorized identity can export it, you have not protected it, no matter how many controls you have in place.

Security incidents and service disruptions are never simple. They are rarely the result of a single mistake, and they don’t only happen to organizations that “did something wrong.” In reality, many of the most capable, well-resourced companies experience them precisely because they operate at scale, under constant pressure, and within complex, interconnected environments.

Even well-maintained Magento and Adobe Commerce environments still land PCI DSS findings against 6.4.3 and 11.6.1. When that happens, it’s usually not a server-side Magento configuration issue. Instead, it’s a client-side runtime governance gap that Magento and most server-side stacks aren’t designed to close, even with helpful guardrails like CSP and SRI on payment pages.

If your latest PCI DSS audit report flagged gaps against Requirements 6.4.3 and 11.6.1, it’s not time to panic yet. These findings are common and entirely fixable. Most of the time, the gap is between static guardrails and continuous runtime governance. QSAs assess whether you have active control over what executes in the client browser, not simply whether guardrails are configured. That is also why traditional controls like CSP or manual reviews can feel complete and still fall short.

If you look at an enterprise architecture diagram from five years ago, it looks relatively tidy. You had a data center, maybe a cloud provider, and a few gateways. Today, that diagram looks like a constellation. Data is living in AI platforms like Databricks. Frontend applications are pushed to the edge on Netlify. Logic is scattered across microservices, serverless functions, and legacy IIS servers. For security teams, this fragmentation creates a massive headache: Blind Spots.
