Heartbleed: Packet Capture

Filed under: Networking,Vulnerabilities — Didier Stevens @ 21:39

I could call this a cardiogram, but let’s not get carried away…

I took a packet capture of the heartbleed bug (CVE-2014-0160) in action: I have OpenSSL 1.0.1 14 March 2012 running on Apache2 (Ubuntu, VMware) and executed Jared Stafford’s ssltest.py script. One small modification to the script: I removed line 132 (the script transmits 2 heartbeat requests, I want only 1 request).

PS: as I expected, I didn’t find an entry in the Apache logs for this request.
