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.

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.
