# The numbers: every version

This section is a projection of the site's data, rebuilt on every release. It is written for Alex, curious reader. A new version is recorded only when the text a reader sees changes, so a release that changed something elsewhere leaves this section's version alone. It has 4 versions; the newest is first, and each is shown as the changes from the one before. [Read the current version →](../../numbers/index.html)

# The numbers: 70%, 30 million, 2.6 million, 6,000, 674 Every scale figure in circulation about php2shell, with what it measures, who said it, whether anyone checked it, and why they differ by four orders of magnitude. # The numbers, and what each one measures The editor's starting point for this site was a figure that did not add up: *70% of the internet*. It turns out to be a headline's restatement of a share-of-websites statistic that nobody on this beat sources, sitting next to a host count a thousand times smaller and a national count a thousand times smaller again. None of them is wrong on its own terms. The table says what each one counts. | Figure | What it measures | Who said it | Status | Note | Sources | |---|---|---|---|---|---| | 70% the Internet | Not stated. The headline is a restatement of the body's figure for websites. | Wiz (headline and X post) | unverified | The BBC says it could not independently verify this figure. The body of the same Wiz post says PHP 'powers 70% of all websites in the world' and cites no measurement. | Wiz Wiz on X | | almost 70% websites | The share of websites whose server-side language is PHP, as commonly published by web-technology surveys. Neither page names the survey. | Cloudflare; OpenAI ('an estimated 70% of websites') | reported | A share of websites is not a share of the Internet, and a site that uses PHP is not a site that is reachable, unpatched and exploitable. | Cloudflare OpenAI on X | | about 30 million websites | Not stated. | Alan Woodward, Surrey Centre for Cyber Security, on the BBC | reported | Second-hand through the BBC. No basis given. | BBC News | | 2,608,039 internet-facing hosts running PHP | Hosts observed on the internet that expose PHP, as counted by one scanning vendor. | VulnCheck, via The Hacker News | reported | A host count, far smaller than any websites figure, because one host serves many sites and most sites are behind hosts that do not expose PHP directly. | THN | | about 6,000 potentially affected resources in Latvia, a few hundred in the public sector | Resources identified by the national CERT as potentially affected, in one country. | CERT.LV | reported | The one national-scale count from a primary source, and the only one that says 'potentially'. | CERT.LV | | 674 software entries in the NCSC-NL php2shell inventory | Rows in the inventory: 206 marked Vulnerable, 46 Fix, 418 Investigation, 3 Not vulnerable, 1 without a status. | NCSC-NL, counted from the file at commit cca173c64ec5 | confirmed | NCSC-NL calls the entries investigation leads until a vendor backs them. Counted by this site's export script, not copied from a page. | NCSC-NL NCSC-NL | | 9.2 CVSS v4.0, each CVE | CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N | PHP Group as CNA; GitHub advisories; CERT-EU; ACN | confirmed | The 10.0 that circulated on 20 October is wrong, per the PHP Foundation; a PHP security team member traces it to a social post relayed by a vendor and a news site. | CVE record CVE record PHP CERT-EU ACN / CSIRT Italia | | 10.1 million views of the NSA Cyber post, at capture | The view counter X displayed when the post was captured. | X, as displayed at 2026-10-22T08:09Z | confirmed | A capture-time number; it will be higher now. | NSA Cyber on X | | 4 days before disclosure, an exploit attempt hit an Amazon honeypot | 17 October 2026, MadPot honeypot, one attempt from an anonymisation network. | CJ Moses, Amazon, via The Hacker News | reported | Amazon's own post has not been found; the quote is as The Hacker News printed it. | THN | | about 9 hours before disclosure, Cloudflare's WAF rules went live for all customers | 21 October 2026 03:02 UTC against the 14:00 UTC release. | Cloudflare | confirmed | Primary party. No attack volumes are in the post. | Cloudflare | | more than 6 hours before the coordinated release, Chainguard published built images with the fix | 21 October 2026 07:41 UTC. | The PHP Foundation | reported | Chainguard reportedly does not dispute the time but denies leaking; that article is blocked from this environment. | PHP Foundation | ## Why they differ by four orders of magnitude - **A share of websites that use PHP** (about 70%) is the population a survey counts by looking at response headers and page markup across a sample of the web. It includes every site on a shared host that patched hours ago, every site behind a CDN, and every site that has not been touched since 2019. It is an upper bound on exposure. - **Internet-facing hosts that expose PHP** (2.6 million, one scanner's count) is a count of machines, not sites. One host serves many sites; most sites sit behind hosts that do not announce PHP at all. It is a lower bound on the machines an attacker could reach directly. - **Websites that could be affected** (30 million) has no stated basis. It may be a fraction of a websites total; it may be a guess. - **Resources potentially affected in one country** (about 6,000 in Latvia) is the only figure from a body that could inventory what it counts. Scaled naively by population it would put the EU in the low millions, which is a different number from any of the above and is not offered here as one. - **Products in an inventory** (674) counts software, not deployments: one row is WordPress, another is a Linux distribution's package. The number a reader actually wants, how many systems were exploitable at a given hour and how many were exploited, does not exist in any captured source. What exists is a set of signals, on the exploitation page. [Every section, across every release →](../index.html)
