Attack type
Vendor compromise, surfaced before the invoice clears.
Attackers impersonate your vendors, your customers, and your trusted partners — increasingly in messaging, because that’s where your finance team handles the time-sensitive requests.
What we see in the wild
The patterns landing on your employees’ phones.
“Our banking details changed — please update before this week’s payment”
Spoofed account-manager handoffs around personnel changes at your vendors
DocuSign and SignNow lookalike requests with credential-harvesting back-ends
Coordinated multi-touch sequences: email, then SMS, then phone, all impersonating the same vendor
Why traditional tools miss it
Your AP system trusts the vendor. Your SEG can’t see the SMS follow-up. The fraud completes inside the trust boundary you’ve already established.
How SmishAlert surfaces it

FAQ
Questions security leaders ask
How do I detect vendor impersonation and invoice-change fraud?
Vendor fraud completes inside a trust boundary your AP system already honors, and the SMS follow-up never touches your email security. SmishAlert flags banking-change and invoice-change patterns at the device and correlates them against known vendor-impersonation campaigns.
Why does business email compromise now use text messages?
Finance teams handle time-sensitive vendor requests over messaging, so attackers add an SMS or phone touch to lend legitimacy. SmishAlert captures these multi-channel sequences and routes findings to finance and the SOC.
Can SmishAlert catch DocuSign and e-signature lookalikes?
Yes. DocuSign and SignNow lookalike requests with credential-harvesting back-ends are common vendor lures. SmishAlert flags them on-device and links them to the broader campaign.
What does a vendor-impersonation exposure pilot measure?
A 30-day SmishAlert exposure pilot quantifies invoice-change attempts, impersonated vendors, and finance staff targeted, and identifies any coordinated multi-touch sequences.
