[eta] found herself in a flat with several LKV373 HDMI extenders. Find the corresponding transmitter, plug it into your device, and you’ve got a connection to the TV/sound system, no …read more Continue reading Audio, Not Video Over The LKV373 HDMI Extender
It sometimes seems like there are two kinds of cheap hardware devices: those dependent on proprietary software that is no longer available and those that are equally dependent but haven’t …read more Continue reading Reverse Engineering Reveals Hidden API in Abandonware Trail Camera
I’m envisioning myself walking around my home with a small laptop in one hand, and a smartphone in the other hand. The laptop would have wireless security software (WireShark, maybe nzyme or similar) running on Linux. The smartphone woul… Continue reading Install Linux on Chromebook for wireless security testing?
I have managed to decrypt TLS 1.2 data using Wireshark on a connection from the browser to the WCF service, but cannot manage to do the same with the WCF client.
I’m not sure what is the difference, because in both cases the cipher suite s… Continue reading Wireshark decrypt TLS 1.2 from WCF client
When I opened up Wireshark, I noticed pings from an IP from Taiwan, and I am suspicious about it. It happens like every couple of seconds from the second I boot up my laptop. I used whois and it said the netname is HINET-NET and the source… Continue reading Suspicious ICMP ping to/from my laptop [closed]
A security engineer told me that my computer must have a trojan horse, but it has not been found yet.
The security engineer captured and analyzed traffic pcap files with Wireshark, and said that there was a problem in the pcap file.
The se… Continue reading Does wireshark detect all unauthorized access?
The sequence number should be a 64 bit number in every TLS record, but the record header layer is only 5 bytes long and I am looking at a Wireshark pcap, where the TLS record only includes the header and encrypted application data. There i… Continue reading Where in the TLS 1.3 record is the sequence number located? [closed]
I’ve got a PCAP file that has 3,445 HTTP "206 Partial Content" packets for the application/pdf media type. Each of these requests is for the same file, different Content-Ranges are being requested each time as a covert means of d… Continue reading Why is the output of tshark `http.file_data` different from the Content Length? [migrated]
I am currently trying to learn the TCP session creating (3 way handshake) process in detail. I was wondering what the sequence number means and also why is the ack num for the next ACK packet always the sequence number of the previous pack… Continue reading What is sequence number and why is it used as the ACK number for the next ACK packet? [closed]
I have a desktop application on Windows that connects to a server which I don’t have access to. I want to reverse engineer an API for personal use so I can connect from a custom interface instead of using the official application.
Using Wi… Continue reading Decrypting TLS traffic from windows desktop application [closed]
