Telnet Echo Hex Escape Sequence Output

Matches Telnet sessions where echo -e is used with hexadecimal escape sequences (e.g., \x61\x75\x74\x68\x5F\x6F\x6B\x0A) to construct and output decoded byte strings. This technique is commonly used to reconstruct payload strings, generate markers, or write staged content using encoded byte values instead of plain text.
