In plain words
Imagine you receive an email that looks like it's from someone you trust, but it's actually a scam to get you to click on a link or open a file. This is similar to what's happening with a type of phishing called CSuite, where attackers send fake emails to steal access to Microsoft 365 accounts¹. Think of your Microsoft 365 account like your house, and the attackers are trying to get a key to unlock it.
How it actually works
The attackers use this stolen access to deploy remote-access tools², which are like master keys that allow them to control the compromised accounts remotely. This means they can use the accounts to do whatever they want, like stealing sensitive information or using the accounts to send more phishing emails.
What it means for defenders
Defenders can detect this type of attack by monitoring for unusual activity in Microsoft 365 accounts, such as unexpected login locations or access to sensitive information. They can also stop it by educating users about phishing attacks and how to avoid them, as well as implementing additional security measures like two-factor authentication³.
