Windows 10: WUDO packet structure

Hello everyone.I have a question. Recently our SOC they send us a alert from a computer that is connect to the guest WIFI is try to talk with other computers at the LAN wired. They questions is what is the packet stracture for the WODU? The packets is sending to multicast ip, the global broadcast ip 255.255.255.255 or on a dedicated host ip? ThanksBest Regards SG

C/C++/C# Packet Sniffing FAQ and How-To

hi oliver

Oliver...
i m getting packets on my network and i m suppose to map those packets

Incoming packet at the front end can be interpreted by mapping onto the following structure.
Struct {
char cNetId[2];
short iNoPackets;
CHAR cPackData[512];
} BcastPackData;
whence,
cNetId[2] Identifies the machine
iNoPackets The number of packets that are sequentially packed
cPackData Buffer containing all the packets.
The buffer when mapped to, by the above structure the number of packets in the buffer can be known. The
next task is to segregate the packets and process the individual packets




Map the incoming buffer onto the structure described in section 1.19.3
Check the net id and number of packets from the structure as described in section 1.19.3
Refer to the section 1.19.3 for the components packet in the structure and the diagram in section 1.19.2
Map the individual packets ( 1st packet, 2nd packet, and so on… ) onto the structure
struct {
short iCompLen;
CHAR cCompData[MAX_MESSAGE_SIZE];
}BcastCmpPacket;
N.B. The above structure is currently used to interpret the incoming packets.



can you help me build the utility on above parameters...
i appreciate any help from you pal.

thanks mate

 

C/C++/C# Packet Sniffing FAQ and How-To

Very nice. Got a question though: is it possible to find out what packets are going to and from each process? You say on step 6 that the OS directs the packet to the process.. But is it possible for we, as the programmer, to intercept this and then perhaps filter all the packets so only packets going to and from suchandsucha.exe are shown?

 

Need a book for Data Structures

Many good suggestions here
