Riding Hood Solutions – Threat Brief | May 4th, 2025
1. New Microsoft Teams Phishing Tactic Bypasses MFA
Threat: Attackers are sending fake Teams meeting invites that redirect users to lookalike Microsoft login pages. Even users with MFA are vulnerable if they approve a malicious prompt.
Tactic: “MFA fatigue” attacks — repeated login prompts until the user clicks “Approve.”
Action: Train users to report suspicious MFA requests. Use phishing-resistant MFA (like FIDO2 keys) for sensitive accounts.
2. Apple Zero-Day Exploited in iMessage (CVE-2025-15192)
Threat: A zero-click exploit was discovered in iMessage, allowing attackers to execute code without user interaction.
Impact: High-profile targets, journalists, and activists are being monitored.
Action: Immediately update all Apple devices to the latest iOS/macOS versions. Disable iMessage on devices that don’t require it.
3. Google Workspace Scam Targets Small Businesses
Threat: A phishing campaign is impersonating Google Admins, urging users to “verify their domains” or risk suspension.
Tactic: Victims are sent to a malicious Google-style login page, where credentials are harvested.
Action: Remind clients and employees: Google will never threaten to suspend you via email without showing alerts in the dashboard. Always log in via direct links, not emails.
4. Rise in Fake Tech Support Calls from “Bank Fraud Teams”
Threat: Attackers are posing as fraud departments from major banks, claiming there's suspicious activity — then guiding users to “secure” their accounts through remote access tools like AnyDesk or Zoho Assist.
Tactic: Social engineering + scare tactics.
Action: Never install remote software at someone’s direction. Hang up and call the bank directly using the number on the back of your card.
5. AI Voice Cloning Used in Family Emergency Scams
Threat: Criminals are now using AI-generated voice clones to impersonate loved ones in distress, particularly targeting elderly individuals.
Tactic: “Hi Grandma, I’m in trouble, I need help...” — followed by urgent money requests.
Action: Create a family verification code word system. No code, no cash. Spread awareness among family and community members.
Tip of the Week:
Use App-Based MFA, Not SMS: SMS can be intercepted. Use app-based MFA like Microsoft Authenticator or Authy, or hardware keys for critical accounts.
