Your question doesn't make sense. A pcap is a file containing captured traffic, it can't be used to patch anything. Maybe there's a language problem, can you maybe rephrase the question?
What do you mean by "patch the attack"? "Patch" is generally used to mean something you do to a program, not to a pattern of network traffic trying to overload your machine, which is what a network DoS is, Do you mean that you want to search through the pcap to find the traffic that's attacking your machine?
It seems you have a lot of skills to learn.
Start by reading the PCAp file and understanding the protocol.
Then learn you IPD/IDS system to understand how virtual patching works and how you can creat your own virtual patches.
My guess is that you need to invest something worth of a month in to this process of learning the protocols and learning how to use the right tools.
There is now quick fix here as it will only be a stopgap for 1 very specific type of hole
Cant you get the hex string to an attack and patch the attack through IP Tables? Im just wondering how I get the hex string and how to drop traffic with the same hex string with IP Tables. I also want to know how to find the specific IPs coming from the DDoS attack through a pcap that captured a DDoS attack
