| As of 14:40 UTC on 25 October, no named organisation has said it was compromised through php2shell. Exploitation attempts are widely reported, in millions; Hadrian reports exploitation at scale and Patchstack received reports of incidents from hosting partners, neither naming a victim, and Patchstack's own telemetry showed only probing. Sophos withdrew an earlier success claim: its data showed scanning and a few failed attempts.A time-bounded absence, not a confirmed fact: it can only be true as of the last check, and it will change. Changed from "confirmed" on 22 October at the editor's request. Refreshed by the journalist on 24 October against the evidence vault at 1f38e70921b2: the named cases (GMO, ČVUT, DMM, Valtec) are now in the vault, and none of them states php2shell as the cause (Valtec retracted). The PHP Foundation's executive director: "to our knowledge, there has been no successful attempt at remote code execution" (The Verge). Luxembourg: no institution has announced an intrusion (Paperjam). Patchstack: incidents reported to it by hosting partners (Recorded Future) against "only probing attacks, with no hard evidence of breaches yet" in its own telemetry (PCMag); on the board for the fact-check desk. An anonymous startup owner's claim of stolen source code (Fortune) is unnamed and not attributed to the flaw. Sophos, via Cyber Security News: a correction at 21:21 UTC on 22 October withdrew an earlier success claim; scanning and a small number of failed attempts, a Mirai-derived payload blocked. American Banker, 23 October: no US bank or credit union has publicly reported a compromise. Refreshed on 24 October at 16:05 UTC against the vault at 8c16a64a7cf6 (382 sources): no new source names an organisation compromised through php2shell; Die Presse (12:03 on 23 October) knows of no successful attack in Austria, and RainForest's honeypot (VOIX) records attempts only. Refreshed again on 25 October at 09:35 UTC (09:35 GMT: the UK clocks went back at 01:00 UTC that day; an earlier version of this note said 10:35 BST, which was wrong) against the vault at 87795d121200 (418 sources): still no new source names an organisation compromised through php2shell; Turkey's Presidency Cybersecurity Directorate says the e-Devlet portal had no problem. Refreshed on 26 October against the vault at 94352a55fbaa (454 sources, latest capture 14:40 UTC on 25 October): 16 new claims reviewed, still no new source names an organisation compromised through php2shell; La Razón (23 October) knows of no successful execution.
