The netcat file-transfer quick reference: flags, a modular cheat sheet, and worked breakdowns. Listen and save, connect and send, close cleanly with -N or -q0, stream a directory with tar, encrypt with socat OPENSSL, fall back to bash /dev/tcp when nc is missing, and checksum to catch truncation.
The HTTP file-transfer quick reference: serve a folder from your attacker box in one line, then pull files onto the target with wget, curl, certutil, PowerShell, or curl.exe. Flags, a modular cheat sheet, in-memory execution, upload-back with updog, checksum verification, and beating egress filters by serving on 80 or 443.
The file-transfer quick reference: the serve-and-pull vs push-and-receive decision, a modular copy-paste cheat sheet, and a worked breakdown of every method. Serve a folder over HTTP, pull with wget or certutil, host an SMB share, move a file with netcat or socat, copy over scp, paste a base64 blob, and checksum both ends.
The socat quick reference: flags, a modular copy-paste cheat sheet, and a worked breakdown of every real situation. Verbose TCP client, port forward, UNIX-socket-to-TCP bridge, TLS wrap, hex-dump a protocol, upgrade a reverse shell to a full PTY, and a virtual serial pair.
The wget quick reference: install and verify, a modular copy-paste cheat sheet, and one command for every real situation. Resume a broken download, mirror a site for offline viewing, pull a list of URLs, reuse a login cookie, POST a form, and rate-limit to stay quiet.
The TShark quick reference: flags, a modular copy-paste cheat sheet, and a worked breakdown of every real situation. Read a PCAP, filter by BPF or display syntax, extract clean fields, follow a TCP stream, pull cleartext creds, carve files out of HTTP, and spot a port scan.
The tcpdump quick reference: install and verify, the flags you actually use, a modular BPF cheat sheet, and one command per real situation. Isolate one host, watch a single service, catch DNS, filter by direction or protocol, read clear-text payload, save a clean PCAP for Wireshark, and rotate long captures unattended.
The RustScan quick reference: flags, a modular copy-paste cheat sheet, and a worked breakdown of every real situation. Sweep all 65535 TCP ports in seconds, hand the open ones to Nmap for versions and scripts, scan a subnet or a file of hosts, fix too many open files, tune speed on a laggy link, and pull a greppable port list.
A practical Chisel guide: tunnel TCP and UDP over HTTP, build a reverse SOCKS pivot from a foothold, reach internal hosts, and keep the noise low in a lab.
The Nmap quick reference: flags, a modular copy-paste cheat sheet, and a worked breakdown of every real situation. Ping-sweep a subnet, scan all 65535 ports, fingerprint service versions, run safe NSE scripts, scan UDP, get past a blocked ping, and save output for your notes.
The curl quick reference: flags, a modular copy-paste cheat sheet, and a worked breakdown of every real situation. POST JSON, follow redirects, reuse cookies, pin DNS, resume a download, ignore a self-signed cert, time a slow endpoint, and proxy through Burp.
A practical Responder guide: install it, pick the right interface, start in analyze mode, capture lab name-resolution traffic safely, read the output honestly, and keep a cheat sheet you will actually reuse.
The netcat quick reference: flags, a modular copy-paste cheat sheet, and a worked breakdown of every real situation. Check a port, grab a banner, hand-speak HTTP or SMTP, scan a small range, move a file or a whole directory between lab hosts, dial through a SOCKS proxy, and catch a reverse shell.
