From TimThumb to wp2shell: 25 Years of WordPress Mass…

TL;DR: wp2shell (CVE-2026-63030 chained with CVE-2026-60137) matters because it is a core, pre-authentication RCE reachable on a stock, plugin-free install. That is the rare category. In 25 years, unauthenticated code execution against a bare WordPress install has happened only a handful of times. The overwhelming majority of WordPress mass compromise has ridden the plugin and theme supply chain and infrastructure abuse, not core. This post maps the history so you can see where wp2shell actually sits.

WP2SHELL Update

This morning I’ve started to see exploitation attempts on pwndefend.com (they all failed because like about 80% of sites (based on sampling) this site automatically patched, but also, this site has word fence, is fronted by Cloudflare.

Global Exposure

On the 18th (AM) I did sampling of about 3.5K hosts and found ~20% were not patched. The cyber apocalypse is not seemingly here today! (let alone the fact that if every WordPress site was popped, the world would probably not end)

In the ‘world of Mythos’ and other such overhyped AI buzz words…. the fundamentals of digital security still apply. Don’t get me wrong, I think LLMs are great, as a digital defender, I’ve been using LLMs relatively for a long time now (from offence to defence to general CTI/Research) so I’m not a hater, they are like an Iron Man suit! But we still need our Tony Stark and Pepper Potts!

It’s very easy in a world full of complexity to oversimplify, it’s very easy to focus on one class of threat and ignore another. Zero days sound cool, when mass exploration occurs, it’s a real problem, but for the day to day in an org, authentication attacks (identity plane) are the number one thing you will likely be seeing (if you look at our logs… you have logs right???)

Cyber Myth: Attackers only have to be right once,…

Our cyber world is full of myths and FUD:

Attackers only have to be right once, Defenders have to be right all the time!

Firstly, let’s cut straight to the chase, I can only assume that someone who says this is ignoring or is unaware of how computer systems and intrusions work. But surely this is a true phrase, I’ve seen it repeated over and over again on LinkedIn, so it must be true right?

Email Security: An Enablement Journey, Not a Maturity Ladder

Most organizations treat email authentication as a checkbox exercise. Deploy SPF, publish DMARC in reporting mode, call it done. But the real story isn’t about maturity tiers—it’s about what you unlock at each phase of implementation. And frankly, the gap between where organizations are and where they need to be is brutal.

This post outlines an enablement journey: each phase builds on the previous one and creates new capabilities that weren’t possible before.

The State of DNS Security — Where the Top…

A position snapshot of the full Majestic Million across three layers — DNSSEC signing, email authentication (SPF / DMARC / MTA-STS), and DANE. This is the scorecard: what is deployed, on how many domains, and how it’s distributed by rank and TLD. Remember Majestic Million is a bit old so a chunk of the domains no longer resolve, but the data gives a good thematic view.
