The Takedown Chain · lesson 1 of 3

Five parties

After this lesson you can

Name every party who can remove a phishing site and what each is able to act on.

Assumes you have read The window closes.

Five different parties can affect a phishing site, each with a different scope of action, a different threshold and a very different speed. Knowing which is which is most of running a takedown well.

The chain

PartyCan doActs onTypical speed
Hosting providerRemove the content, suspend the accountClear evidence of phishing on their infrastructureHours to a day, for a provider with a real abuse process
CDN or proxy in frontStop proxying, sometimes disclose the originVaries widely. Some act quickly; some consider themselves a neutral conduitHours to never
RegistrarSuspend the domain — the durable fix, since it survives rehostingEvidence of abuse, usually a higher bar than the host appliesA day to a week
Certificate authorityRevoke the certificateMisissuance, or issuance to a domain used for fraudDays, and revocation rarely stops the attack
RegistrySuspend at the registry level, above the registrarOnly when the registrar will not act, and usually only for their own TLD policy breachesDays to weeks

Host stops it, registrar ends it

Host suspension:
   fast, and the attacker rehosts the same domain
   somewhere else in an hour.

Registrar suspension:
   slower, and the domain stops resolving entirely.
   Rehosting does not help them.

So: host first for speed, registrar for permanence —
and capture evidence before either, because the first
one to act destroys what the second one needs.

Why revocation rarely helps

Certificate revocation is widely requested and does very little. Browsers check revocation inconsistently, a revoked certificate often continues to work in practice, and the attacker can obtain another in minutes from any CA. Request it when there is a genuine misissuance to report, and do not treat it as a takedown route.

The registry is a last resort, not an escalation ladder

Registries generally decline to intervene in matters between a registrar and its customer, and reserve action for breaches of their own policies. Going to them first because it sounds more authoritative wastes a week and irritates the party you will ultimately need.
