Plain-English summaries of active threats targeting Florida businesses — what is happening, who is at risk, and what to do next. Updated as new advisories warrant.
This log provides general security awareness — not a substitute for a professional risk assessment. If you are unsure whether your business is protected, contact ITNS for advice.
Ransomware Operators Now Demand Payment to Prevent Data Leaks
Ransomware groups have shifted tactics and are now routinely threatening to publish stolen client records, contracts, and patient information unless payment is made. This double-extortion approach is affecting Florida healthcare practices, law firms, construction companies, and professional service providers that store sensitive digital files.
Read advisory →AI-Cloned Executive Voices Used in Live Wire-Fraud Calls
Fraudsters are using AI-generated voice clones of CEOs, owners, and attorneys to call accounts-payable staff and authorize urgent wire transfers. The voices sound convincing on a quick phone call — especially when the caller claims to be traveling or in a meeting.
Read advisory →Attackers Abusing Legitimate Remote-Support Tools to Access Networks
After a phone scam or phishing email, victims are coached to install ScreenConnect, AnyDesk, TeamViewer, or similar tools. Criminals then use that session to deploy ransomware, steal credentials, or browse file shares — often bypassing traditional antivirus because the tool itself is legitimate.
Read advisory →Ivanti and Legacy Remote-Access Gateways Actively Exploited
Threat actors continue targeting Ivanti Connect Secure, Policy Secure, and other remote-access appliances with known vulnerabilities — often before patches are applied. Successful exploitation gives attackers VPN-level access without stealing a single password.
Read advisory →Fake Microsoft Teams Voicemail and Meeting Invites Delivering Malware
Attackers send emails that look like Teams voicemail notifications or external meeting invitations. Links lead to fake Microsoft sign-in pages or prompt users to install malicious 'Teams add-ons' and browser helpers.
Read advisory →SharePoint and OneDrive 'Shared Document' Phishing Surge
Emails claiming a vendor, client, or auditor shared a confidential file via SharePoint or OneDrive link victims to credential-harvesting pages. Because real businesses use these links daily, the lure blends into normal workflow.
Read advisory →Active Phishing Campaign Targeting Microsoft 365 Sign-In Pages
Attackers are sending convincing emails that mimic Microsoft password-expiry notices and lead to fake login pages designed to steal credentials and session cookies — giving them access even after you change your password.
Read advisory →Ransomware Groups Increasingly Targeting Small Business Backup Systems
Recent ransomware operations are not just encrypting production servers — they are hunting for backup appliances, NAS devices, and cloud sync folders to destroy recovery options before deploying encryption.
Read advisory →Business Email Compromise (BEC) Wire-Fraud Attempts on the Rise
Fraudsters are impersonating executives and vendors via compromised or spoofed email accounts, pressuring accounts-payable staff to change wire instructions or rush payments before end of day.
Read advisory →Unpatched VPN and Firewall Appliances Exploited in the Wild
Threat actors continue exploiting known vulnerabilities in edge devices — VPN concentrators, firewalls, and remote-access gateways — to gain initial network access without triggering antivirus alerts.
Read advisory →Fake IT Support Phone Calls Targeting Florida Business Staff
Scammers are cold-calling employees claiming to be from Microsoft, your ISP, or your IT provider — then requesting remote-access software installation or login credentials to 'fix a virus.'
Read advisory →Employees Pasting Sensitive Data into Public AI Chat Tools
Staff are using free AI chatbots to draft emails, summarize documents, and analyze spreadsheets — sometimes pasting client names, financials, or PHI without realizing that data may be stored or used for model training.
Read advisory →QR Code Phishing ('Quishing') in Email and Parking Lot Notices
Attackers embed malicious QR codes in emails, PDF invoices, and even physical stickers on parking meters or office doors — bypassing traditional link-scanning because victims scan with personal phones outside corporate security controls.
Read advisory →Credential Stuffing and Password Spray Against Cloud Accounts
Automated bots test stolen username/password pairs from past breaches against Microsoft 365, Google Workspace, and industry SaaS portals — succeeding when employees reuse passwords across personal and work accounts.
