Ilia Zavialov: digital security consultant on crypto, scams and protection
English version for the United States.
Digital security consultant. Individuals, families and small organisations.
Ilia Zavialov is a digital security consultant. In Russian language publications the same author appears as Илья Завьялов and, in the full form, as Илья Николаевич Завьялов. This site collects his published work on the decisions ordinary people make under time pressure: whether to pay, whether to install, whether to sign, whether to grant access.
01What Ilia Zavialov writes about
Four subjects run through everything published by Ilia Zavialov. Each one is developed in the blog, in the order in which a reader actually meets it.
How crypto actually works
Wallets, keys, custody, exchanges and transfers, explained through what happens to the money at each step rather than through the technology.
Types of scams and how they are built
Each scheme taken apart in the order it unfolds: where the first contact comes from, where the moment of loss sits, and which step the whole thing depends on.
Protection that actually holds
Structural checks instead of judging people: what a genuine procedure looks like, which settings survive an attack, and what works when everything else has failed.
The first hours after an incident
What to do when access or money is already gone: stop the ongoing loss, preserve evidence, report, and only then pursue recovery.
Scam in numbers
What the published reports actually say about where money goes, which categories dominate the counts and which dominate the losses, and what that changes for one person.
A face from one photograph
How a single public photograph becomes the face of a fraudulent advert, and what remains checkable once it does.
How exchange scams are built
The anatomy of a fraudulent crypto exchange, from launch to shutdown, and what courts can do afterwards.
Blocked withdrawals
Why a demand to pay a fee before funds can be withdrawn is the whole scheme, and how a genuine delay on an exchange looks different.
Crypto recovery
How offers to return lost coins are built and why the money does not come back
Signing in without a password
What a passkey actually is, why phishing stops working against it, and how far the switch has gone by 2026.
Seed phrases
How recovery phrases work, why a genuine support desk can never use one, and what happens the moment the words reach a stranger
Checks before a transfer
What to verify before money leaves a wallet, and why the check has to happen before rather than after.
Wallet drainers
How approval phishing empties a crypto wallet without ever touching a password or a seed phrase, and how to revoke permissions already granted.
