What to look out for today
Be on alert for fake “verify you are human / security check / CAPTCHA” screens (sometimes called ClickFix or FakeCaptcha) that appear when browsing. These lures are being used to trick staff into actions that lead to password theft and follow-on compromise.
Also expect a spike in impersonation scams (e.g., an attacker posing as “IT” or “security” to persuade a staff member to share information or approve access).
Why this matters to smaller businesses
- Password theft is one of the fastest routes into email, Microsoft 365/Google Workspace, payroll/finance systems and customer data.
- Stolen accounts can be used to send convincing invoices and payment-change requests from a real mailbox.
- “Initial access” malware is commonly associated with ransomware and business disruption later on, even if the first symptom looks like a simple login issue.
- Impersonation works especially well in small teams where people are busy and processes are informal.
Warning signs
- A website suddenly shows a “verification” or “CAPTCHA” that feels out of place, especially on a site you’ve used before.
- Instructions that urge staff to “fix” something quickly, or to follow unusual steps to proceed.
- Unexpected multi-factor authentication prompts, password reset emails, or login alerts.
- Colleagues receiving strange messages from your account (especially asking for urgent actions or sharing links).
- Someone contacting staff claiming to be “IT/security” and asking for codes, approvals, or to install/allow something.
How attackers may exploit the situation
- Credential theft: capturing Microsoft 365/Google passwords, then using them to access mailboxes and files.
- Session/account takeover: logging in as a real user to bypass basic controls and send internal phishing.
- Follow-on compromise: using stolen access to reach line-of-business systems or sell access to other criminals, potentially leading to ransomware.
- Social engineering chains: impersonating internal teams (IT/security/finance) to persuade staff to approve access or share sensitive info.
What to do today
- Brief staff (2 minutes): “If you see a sudden ‘verify’/CAPTCHA pop-up or odd security prompt, stop and report it. Don’t follow unusual instructions.”
- Prioritise MFA hygiene: ensure MFA is enabled for email, admin accounts and finance/payment tools; review any recent suspicious MFA prompts.
- Harden Teams meetings: if you use Microsoft Teams, consider enabling the new policy option to block identified external bots from joining meetings.
- Watch finance workflows: remind the team that bank detail changes must be verified out-of-band (known number, not the email thread).
Ask your IT provider
- Are we seeing any indicators of ClickFix/FakeCaptcha-style threats in our web/email security logs?
- Do we have conditional access / MFA controls that reduce the impact of stolen passwords?
- Can we enable (or have we enabled) the Teams meeting policy to block external bots?
- What’s our process if a user reports a suspicious verification pop-up—do we isolate the device, reset sessions, and review sign-ins?
Patch watch - only one short paragraph, and only if relevant
Separately from the security items above, Microsoft has acknowledged that some August 2026 updates can disrupt printing and PDF export in .NET WPF apps. If you rely on a Windows-based line-of-business app for printing or PDF generation, ask your IT support to validate business-critical workflows after updates (and be ready with a rollback/mitigation plan if needed).
One action today
Send a short internal note today: “If you see an unexpected ‘verify you are human/CAPTCHA/security check’ prompt while browsing, stop immediately and report it—don’t follow unusual instructions or enter credentials.”
