How to Spot, Stop, and Survive a Phishing Attack

Phishing awareness guide for Oklahoma businesses — don't click suspicious links

You think, “I’ll never click a bad link.”
But you clicked this one to get here, and that’s exactly how easy it is to get phished.

Phishing is when a cybercriminal tricks you into clicking a malicious link, opening a fake attachment, or sharing private information often pretending to be someone you trust.
It’s one of the most common ways hackers gain access to business systems, steal data, and deploy ransomware.

At Diverse CTI, we’ve helped Oklahoma counties, cities, and businesses defend against thousands of these attacks before they ever became a crisis.

What Phishing Looks Like

Hackers use social engineering, manipulation and deception to make you believe their message is legitimate.
They often pose as vendors, coworkers, banks, family members or even your IT department.

Common Signs:

  • Urgent or threatening tone (“Your account will be locked!”)
  • Unfamiliar or misspelled sender addresses
  • Links that don’t match the real website
  • Suspicious attachments (ZIPs, PDFs, “voicemails”)
  • Requests for passwords, payments, or verification codes

 The Many Flavors of Phishing

  1. Email Phishing
    The classic version, fake emails that look like official messages from Microsoft, Amazon, or your bank.
    ➡️ Goal: Steal login or install malware.
  2. Spear Phishing
    Highly targeted attacks that mention your name, role, or organization.
    ➡️ Goal: Trick specific employees (often leadership or finance) into sending data or money.
  3. Business Email Compromise (BEC)
    Hackers spoof or hijack a company email account — often a CEO or vendor — to request wire transfers or gift cards.
    ➡️ Goal: Financial theft and internal compromise.
  4. Smishing (SMS Phishing)
    Text messages that look like shipping updates, bank alerts, or password resets.
    ➡️ Goal: Get you to click a malicious link from your phone.
  5. Vishing (Voice Phishing)
    Phone calls pretending to be IT support, tech companies, or even the IRS.
    ➡️ Goal: Pressure you into revealing personal info or downloading software.
  6. Clone Phishing
    A hacker copies a real email you’ve received before but swaps the legitimate link for a malicious one.
    ➡️ Goal: Exploit trust in familiar senders.
  7. QRishing (QR Code Phishing)
    QR codes on flyers, emails, or tables that redirect to credential-harvesting sites.
    ➡️ Goal: Capture passwords or install mobile malware.

If You Already Clicked — Here’s What to Do

  1. Disconnect Right Away
    Turn off Wi-Fi or unplug from the network to stop data theft or ransomware spread.
  2. Contact IT or Diverse CTI
    Forward the phishing message to your IT provider, with the subject line “PHISHING – CLICKED.”
    Include a screenshot and note the time.
    For urgent help from Diverse CTI call 405-840-4100.
  3. Change Passwords Immediately
    Start with the account you entered credentials for, then update your email, Microsoft/Google account, and any reused passwords.
    Enable multi-factor authentication (MFA) everywhere.
  4. Run a Full Security Scan
    Do not open other files or apps. Let your IT provider isolate and clean your device.
  5. Monitor Accounts Closely
    Watch for password reset requests, banking changes, or fake invoices.
    Always verify unusual requests through a known phone number — not the email thread.
  6. Report It Internally
    If your organization has a security or HR team, let them know. Reporting helps prevent others from being tricked.
