If your business uses email and online accounts, you’re a target. Recent industry briefings show another surge in phishing and business email compromise (BEC)—the scams that trick people into handing over logins or changing payment details. The good news: a few practical steps stop most of these attacks cold. This article explains, in plain language, what’s happening and how to protect your business right now.
What’s really going on
- Phishing: Fake emails or texts that look real, often from “your bank,” “Microsoft,” or even your boss, asking you to click a link, sign in, or open a file.
- Business Email Compromise (BEC): A more targeted version. Criminals take over or impersonate a real email account and ask for urgent wire transfers, ACH changes, or gift card purchases.
Why this works for attackers: passwords get reused, inboxes are busy, and one rushed click can expose an account. The fix is not one magic tool—it’s a few layers that back each other up.
Layer 1: Safer sign-ins with MFA or passkeys
What it is: Multi‑factor authentication (MFA) and passkeys add a quick extra step at login—like a phone approval or biometric—so a stolen password alone isn’t enough.
Why it matters: Most account takeovers rely on leaked or guessed passwords. MFA blocks the attacker at the door.
Where to enable first: Email, finance systems (banking, payroll, accounting), remote access (VPN, RDP), and any admin portals.
Tips
- Use an authenticator app or device prompt instead of SMS when possible.
- If your tools support passkeys, turn them on—they’re phishing‑resistant and fast for users.
Layer 2: Backups you can actually restore
What it is: Copies of your important data stored safely so you can get back to work after an attack or mistake.
Why it matters: Ransomware and account lockouts still happen. Tested backups turn a crisis into an inconvenience.
How to do it
- Follow the 3‑2‑1 rule: 3 copies of data, on 2 different media, with 1 copy offsite or immutable.
- Test restorations on a schedule and write down how long a restore takes. If you have never done a restore test, you don’t know if your backups work.
Layer 3: Email filtering plus quick training
What it is: Tools that scan emails for bad links or faked senders, combined with short staff refreshers.
Why it matters: Email is the number‑one entry point. Filters reduce junk, and a 10‑minute refresher helps people spot the rest.
What to enable
- Advanced filtering and impersonation protection for Microsoft 365 or Google Workspace.
- Domain protections: SPF, DKIM, and DMARC to make it harder to spoof your domain.
- A short monthly tip or simulated phish to keep everyone sharp, especially around invoice or bank‑detail changes.
How this looks in real life
A bookkeeper receives a “new bank details” email from a vendor. Filters flag it, the bookkeeper knows to verify changes by phone, and MFA protects the account even if a link was clicked. Worst case, a restore brings back any changed files. No money lost, no downtime.
Quick checklist for this week
- Turn on MFA or passkeys for email, finance, and remote access.
- Move team passwords into a manager and stop sharing via email or spreadsheets.
- Schedule a backup restore test and record the time to recover.
- Enable advanced phishing and impersonation protection; verify SPF, DKIM, and DMARC.
- Create a one‑page “what to do if” playbook: who to call, how to isolate a device, and how to report suspicious emails.
