Next up in our “This didn’t quite make it into the 2021 Threat Report, but is still really cool” series: New backdoors!
Backdoors are a crucial component of a website infection. They allow the attackers ongoing access to the compromised environment and provide them a “foot in the door” to execute their payload. We see many different types of backdoors with varying functionality.
When our malware research team is provided with a new backdoor they need to write what’s called a “signature” to ensure that we detect and remove it in future security scans.
