Crypto wallet drained again in repeat phishing attack
17 August 2026 · Source: startupfortune.com
A crypto wallet was drained of $25.6 million in a phishing attack after the owner approved a malicious transaction. Investigators said the same wallet had also lost about $24.23 million in a very similar attack in 2023.
This matters because phishing often succeeds by tricking people into authorizing payments or access, not by breaking systems. Businesses handling digital assets or high value payments need strong checks on links, approvals, and sender identity, and Sender Registry helps reduce the risk of impersonation and scam messages reaching staff before money moves.
How Sender Registry helps
Impersonation Radar watches certificate logs for lookalike domains the moment they are registered, so a fake is caught before it is ever used against you.
Or share this QR code with someone on another device.
Where is your business based?
You can change this at any time.
How Network Confirmation works
Every object in the registry (a sender, a domain, a campaign) moves through five
stages as independent evidence builds:
UNSEENNothing reported yet.
OBSERVEDOne report exists. A single data point, not yet corroborated.
CORROBORATEDA second, independent organisation has reported the same thing.
NETWORK CONFIRMEDFive or more independent organisations agree.
VERIFIEDTen or more independent organisations, the strongest confidence level.
This is deliberately separate from Risk and Confidence. How much of the network agrees
is a different question from how dangerous something looks, or how certain we are.
How Threat DNA works
Every campaign gets scored across 8 axes: infrastructure, domain patterns, message
templates, link behaviour, attachment patterns, target industries, target roles, and
campaign velocity. All plotted as a fingerprint.
Sender Registry compares every campaign's fingerprint against every other campaign's
using cosine similarity: the same technique used to compare documents by meaning, not
just matching words. A high match (we only ever suggest one above 55% similarity) means
two campaigns that look unrelated on the surface may share real infrastructure, even
under completely different domain names.
How the Intelligence Map works
Senders, domains, URLs, attachments, campaigns, brands and suppliers all become nodes
in a shared relationship graph, built from real evidence: a sender using a domain, a
domain appearing in the same report as another domain, a report belonging to a campaign.
On a phone, we deliberately don't force a giant graph onto a small screen. Instead you
get a focused view: the object you're looking at, and everything directly connected to
it, with a tap to move to any of those connections in turn.
How push notifications work
Add Sender Registry to your home screen and turn on notifications from your account -
both free, both take under a minute. From then on, anything urgent (a payment-diversion
campaign, an executive impersonation attempt) reaches you as a real notification on your
lock screen, the same way any other app alerts you.
Every notification is sent end-to-end encrypted directly to your device - nothing is
readable in transit by anyone other than your phone.
How the QR scanner works
Open Verify Before You Act, point your camera at a QR code, and capture it. The image is
decoded and the destination it leads to is checked exactly the same way we already check
a QR code found inside a forwarded email - the same detection, just with your camera as
the front door.
You'll see whether the destination is safe, blocked, or worth a second look, with a plain
explanation either way.
How sharing to Sender Registry works
On Android, once the app is added to your home screen, "Sender Registry" simply appears
as an option in your phone's normal Share menu - the same one you'd use to send a photo
to a friend. Share a suspicious text or link straight in, review it, and submit.
On iPhone, Apple's own software doesn't allow a website to appear in the Share menu
automatically. A short, one-time setup (a free "Shortcut") gets you the same result -
after that one step, it behaves identically on both phones.
