Copycat AI Assistant Downloads Can Capture Office Logins

Staff searching for popular AI chat and writing tools are landing on lookalike websites and browser add-ons that are not the real product. The copycat can look useful and may even draft a message, while asking to read email, saved passwords, or every site the browser opens. That access can copy client details and login information without a strange attachment or an obvious warning.

Ransomware Can Spread Through Shared Folders and Cloud-Synced Drives

Many ransomware infections start on one computer, then lock every file that account can reach on office shared drives and in folders that sync to tools such as OneDrive or SharePoint. For a small firm, that can disrupt client files, job documents, and billing records across the office even if only one person opened a bad link or attachment. A cloud copy is not automatically a safe backup if the same account can change or delete those files.

Ransomware Often Locks Files Days After a Quiet Break-In

Many ransomware attacks on small offices do not start with a lock screen. Attackers often get in through a stolen password or a clicked email, then spend several days looking around, turning off security tools, and finding shared files before they encrypt anything. Clinics, law firms, construction companies, and professional practices are hit because a short shutdown can stop scheduling, billing, filings, and job payments.

AI-Cloned Executive Voices Used in Live Wire-Fraud Calls

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.

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.

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.

HighPhishing· June 25, 2026

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.

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.

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.

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.

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.'

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.

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.
