Business email compromise is when a criminal gets into, or imitates, a mailbox to redirect payments. For Phoenix firms that send invoices, pay vendors or move client funds by wire, one convincing email can cost more than a year of IT.
Who gets targeted in Phoenix
Suppliers to the semiconductor plants in north Phoenix and Chandler run shop-floor PCs and need stable networks. Aerospace and defense suppliers across the Valley need CMMC preparation. Construction firms keeping up with Phoenix growth need plans, estimates and email on every job site.
Firms like these send and receive payments by email every week, which is exactly what attackers look for.
How mailbox takeovers start
A stolen password, a fake login page or a look-alike domain lets an attacker read mail, set hidden forwarding rules and send payment requests that look real.
Locking down Microsoft 365
Multi-factor authentication, conditional access, safe sign-in settings and mail flow rules close the common ways in. Filtering catches look-alike domains and malicious links before they reach the inbox.
Arizona data rules to know
Arizona’s breach notification law, A.R.S. 18-552, requires notice to affected people within 45 days, and to the Attorney General and the credit reporting agencies when more than 1,000 Arizonans are affected.
A hacked mailbox often holds customer records, so an email takeover can become a reportable breach.
Watching for takeover signs
We monitor for suspicious sign-ins, new forwarding rules, account changes and unusual sending patterns. During office hours an engineer acts on alerts by locking the account, resetting credentials and checking what was sent.
