In 2025, attackers are using the same AI tools your team uses to write emails, summarize documents, and draft proposals. The result: phishing messages that look clean, local, and convincing, plus deepfake audio and video that can sound like your CEO or vendor.
For small and mid-sized organizations around Milwaukee, that changes the game. You’re not just defending against bad spelling and sketchy grammar anymore. You’re defending against good writing and realistic impersonation.
This post breaks down what we’re seeing “in the wild,” why these attacks work, and the practical steps you can take without turning your office into a paranoia factory.
How AI Has Changed Phishing (and Why Old Training Falls Short)
Traditional phishing training focused on:
- Obvious spelling mistakes
- Weird logos or off-brand designs
- Suspicious senders from random domains
Those clues still matter, but they’re less reliable now.
With AI, attackers can:
- Write well-structured, typo-free emails in any language
- Add local details (Milwaukee neighborhoods, your vendor’s name, even your building address)
- Generate lookalike login pages and fake “DocuSign” or “Microsoft 365” prompts in minutes
And that’s just email. We’re also seeing:
- Deepfake-style voicemail (“This is your CEO, can you approve this payment quickly?”)
- Voice cloning used to bypass call-back verification
- QR-code phishing (“quishing”) embedded in posters, invoices, or event badges that go straight to malicious sites
If your phishing training boils down to “watch for bad grammar,” it’s outdated.
What These Attacks Look Like in a Milwaukee SMB
Here’s how AI-powered phishing and deepfake-style scams typically play out for small and mid-sized organizations:
1. The “Perfectly Normal” Invoice
An attacker:
- Scrapes your website, LinkedIn, and public filings to see who you work with.
- Uses AI to write a realistic email “from” a familiar vendor.
- Includes a link to a lookalike payment portal or updated banking instructions.
The email:
- Looks clean
- Uses the right job titles
- References real projects or products from your site
By the time someone notices, a payment has already gone to the wrong account.
2. The “CEO Needs This Fast” Message
An attacker:
- Finds your leadership team on LinkedIn.
- Mimics their writing style, or uses AI to generate executive-sounding language.
- Sends a message from a lookalike domain or compromised email account.
Sometimes they add a voicemail or voice note using AI-generated speech:
“Hey, I’m about to board a flight. Can you push this payment through today? I’ll explain later.”
If your internal process is “we trust what looks urgent from leadership,” that’s a problem.
3. The QR Code That Isn’t Friendly
We’re also seeing more QR-based attacks:
- On printed invoices
- On posters or signs in public places
- In emails that look like shipping or MFA prompts
Staff scan the code with their phone, land on a spoofed login page, and type in their Microsoft 365 or other credentials. The attacker now “logs in” as them and moves quietly.
The Real Goal: Logging In, Not Breaking In
Most of these attacks aren’t trying to smash through your firewall Hollywood-style.
They’re trying to:
- Trick someone into approving an MFA prompt
- Capture real usernames and passwords
- Get inside your Microsoft 365 / Google tenant as a legitimate user
Once they’re in, they can:
- Set up mailbox forwarding rules
- Register their own MFA methods
- Download data or send more phishing emails from a trusted internal account
That’s why we keep saying:
“Attackers don’t break in; they log in.”
Three Practical Defenses That Actually Help
Good news: you don’t need a shiny new tool for every new AI headline.
You need a solid foundation that’s tuned to how these attacks work now.
Here’s where we’re helping Milwaukee clients focus.
1. Stronger MFA and “Stale Method” Cleanup
If your MFA setup is a mix of old methods and “approve all” behavior, AI phishing will find the cracks.
We recommend:
- Number-matching or code-based approval instead of blind “allow/deny” push prompts.
- Device health checks where possible (only trusted, compliant devices can access critical apps).
- Cleaning up old MFA options (no leftover SMS-only or unused phone numbers on admin accounts).
This doesn’t have to be a big-bang change. Start with high-risk users and apps:
- Finance and payroll systems
- Microsoft 365 / Google Workspace admins
- Remote access and VPNs
2. Mailbox Hygiene and App Review
Once attackers are in a mailbox, they rarely announce themselves. They hide.
Two places to check regularly:
- Forwarding rules and inbox rules
- Are emails auto-forwarding to external addresses?
- Are certain messages being silently moved or deleted?
- Connected apps (OAuth permissions)
- Has someone granted a third-party app permission to read or send mail?
- Are there any apps you don’t recognize?
We help clients set a schedule (monthly or quarterly) to review this, especially on:
- Executive accounts
- Shared mailboxes (AP@, AR@, info@)
- IT and admin accounts
3. Real-World Security Awareness (Not Just Slide Decks)
Staff don’t need to become security experts. They just need to get comfortable asking:
“Does this feel right?”
Instead of an annual, generic training, we’re seeing better results with:
- Short, role-specific examples
- AP/Finance: invoice scams and payment change requests
- Front desk / schedulers: appointment, shipping, or registration scams
- Leadership: “urgent approval” and impersonation attempts
- Simple escalation paths
- “If something feels off, forward to this mailbox.”
- “If you accidentally clicked something, tell us now. No judgment.”
When people know how to ask for help and that they won’t get in trouble, they’re much more likely to raise a hand early.
Where Stamm Tech Fits In
For most Milwaukee organizations, the challenge isn’t knowing that AI phishing and deepfakes exist. You see the headlines.
The real challenge is translating that into a calm, realistic plan:
- Which tools and controls should we actually turn on?
- Which users and systems are highest-risk for us?
- How do we explain this to non-technical staff without scaring them?
That’s where we come in.
As a Milwaukee-owned MSP, we help local teams:
- Audit current MFA and sign-in methods
- Lock down Microsoft 365 / Google tenants (rules, OAuth apps, admin accounts)
- Build short, scenario-based training that matches how your people work
- Create a basic incident playbook: “Here’s what we do if someone gets fooled”
No drama. No 40-page PDF. Just a clear, prioritized list and a partner to work through it.
Wondering Where to Start?
If you’ve read this far and you’re thinking:
“We probably have some gaps, but I’m not sure where…”
You’re exactly who this was written for.
Here’s an easy first step:
- Make a short list of your most sensitive systems (email, finance, HR, key line-of-business apps).
- Ask:
- “Do we have strong MFA on these?”
- “Who has admin access, and how is it protected?”
- “If someone got into one of these accounts, how would we find out?”
If those questions are hard to answer, we’d be happy to walk through them with you.

FAQ: AI Phishing and Deepfake Scams for Milwaukee SMBs
Q1: Are AI phishing attacks only a problem for big companies?
A: No. In many cases, small and mid-sized businesses are easier targets because they don’t always have dedicated security teams, strict processes, or advanced monitoring. Attackers don’t care how big you are. They care how easy you are to trick and how fast they can get paid.
Q2: How do I know if an email or voicemail is a deepfake or AI-generated?
A: You often won’t be able to tell just by looking or listening. That’s why we recommend process-based protections instead of relying on gut feel. For example:
- Always verify payment changes through a second channel.
- Call back using a known number, not the one in the email.
- Use stronger MFA and device checks so a stolen password isn’t enough.
Q3: We already have MFA. Are we still at risk?
A: MFA is a huge step up, but it’s not a magic shield. If users blindly tap “approve” on every push, or if old, weaker methods like SMS-only are still enabled, attackers can still slip through. A quick “MFA health check” to remove stale methods and add number-matching/device checks goes a long way.
Q4: Does my staff really need more security training? They’re already busy.
A: Good training should save everyone time, not waste it. Instead of long, generic webinars, we focus on short examples that match real roles:
- AP and finance: invoice and payment-change scams
- Reception/office: fake delivery, appointment, or registration emails
- Leaders: impersonation attempts and urgent approval scams
If people see themselves in the examples, they remember them.
Q5: What’s one thing we can do this month that makes a real difference?
A: If we had to pick one, it would be this:
Lock down your email and identity.
That means:
- Enforcing stronger MFA
- Reviewing admin accounts and mailbox rules
- Tightening access to Microsoft 365 / Google Workspace
Most AI phishing and deepfake-style attacks are trying to get into mailboxes and accounts. Make that a lot harder, and you cut off a big chunk of risk.
Q6: How does working with an MSP like Stamm Tech help with this?
A: We live in this world every day. For local organizations, we can help you:
- Review your current sign-in and MFA setup
- Check for risky mailbox rules or suspicious OAuth apps
- Build a short, clear AI-phishing playbook for your team
- Prioritize changes so you’re not trying to fix everything at once
You don’t need a hundred new tools. You need the right controls turned on, tested, and explained in plain English.
