Plain-English brief. Written for readers who work in a second language.
Key takeaways
- Email bombing precedes Teams access
- Impersonation aids entry
- Trusted software is used
- Access paths repeat across organizations
What happened
The report comes from Dark Reading. Attackers send email bombing messages to target users. Attackers use impersonation to contact users through external Teams chats. Attackers use domain infrastructure to support those contacts. Attackers use trusted software to move toward access to Microsoft Teams.
Why it matters
The same access path repeats across different organizations. Each step uses separate tools to limit reliance on one method. The use of trusted software limits suspicion at the point of contact.
What to do
- Verify external Teams chat requests from unknown senders.
- Check email bombing reports against known inbox activity.
- Limit external chat access to approved users.
