Hi there,

This week’s cyber threat landscape revealed a dangerous shift: attackers are now weaponizing AI tools like ChatGPT to create phishing campaigns that are nearly undetectable. Meanwhile, Microsoft Teams is being used as a backdoor, and geopolitics extends to space-based infrastructure.

Here’s what to watch—and act on—right now.

🧠 Top Threats This Week

🤖 AI-Generated Phishing Campaigns Spike
A new Proofpoint report reveals a 300% increase in phishing campaigns using large language models. These messages are clean, persuasive, and indistinguishable from real corporate communications. Most filters can’t catch them—and even trained eyes get fooled.

Attack Tactic: Fake invoices, vendor requests, and password resets
Defense Tip: Enforce domain authentication (SPF, DKIM, DMARC) and train employees on AI-generated deception

💼 Microsoft Teams Exploited as Malware Vector
Threat actors are using Teams chats to deliver malware—especially where external collaboration is enabled. Malicious links and file payloads are embedded directly in messages.

Fix Now: Disable external sharing by default; require MFA for all collaboration tools

🌍 Russia Probes African Satellite Networks
New intel suggests Russian actors are mapping vulnerabilities in African orbital systems. These satellite links are critical for comms and power infrastructure in emerging markets.

Impact: Cross-border ripple effects; satellite redundancy and defense need urgent attention

🔎 Focus: Can You Spot the AI-Phish?

Here’s a real AI-generated phishing email seen last week:

Subject: Action Required: Finance Platform Login Verification

Hello,
We noticed unusual login activity in your finance dashboard.
Please confirm your identity by clicking the link below:
[Verify Identity]
Thanks,
Security Operations Team

Looks real? It’s fake.
Generated in 30 seconds with ChatGPT. Here’s what gave it away:

  • Vague references (“finance dashboard”)

  • Generic sign-off

  • Link goes to finance-check.io (spoof domain)

✅ This Week’s Security Checklist

✔

Task

🔐

Run internal "Phish or Real?" training

📨

Review email filter rules for AI-scam patterns

🚫

Disable external file sharing in Teams

📡

Brief execs on satellite comms exposure

🔍

Audit spoofable domains with DMARC

🛠️ Strategy Corner

  • AI-Aware Phishing Drills: Use ChatGPT-style emails in your simulations

  • Secure Collaboration Platforms: Limit permissions and external access

  • Spoof-Proof Domains: Check SPF/DKIM/DMARC across all assets

🎯 TLDR

AI phishing is today’s threat, not tomorrow’s. Don’t rely on gut instinct—rely on training, visibility, and email authentication.
