Java Serial Killer

Summary: PortSwigger's BApp Store lists a Burp Suite extension called Java Serial Killer, authored by Eric Gruber, that performs Java deserialization attacks using the ysoserial payload generator tool and requires Java version 8. The listing shows version 1.1.0, last updated 30 January 2017, with an overall estimated system impact rated Low, and notes that extensions are written by third-party users of Burp with no warranty from PortSwigger Web Security.

What you should know: Java deserialization remains a well-known path to remote code execution, and this tooling has sat unchanged since its January 2017 update - a reminder that the exploit utilities attackers reach for are often old, stable, and freely available.
