Explanation

Btlejacking Connection Hijack Command Explanation

Option D (btlejack -f 0x9c68fd30 -t -m 0x1fffffffff) is correct because the -t flag specifically initiates a hijacking (takeover) attack on an existing BLE connection identified by its Access Address (-f), while the -m flag specifies the channel map - all parameters required to actively seize control of an established connection.

Why the distractors are wrong:

• Option A (-j) is used for jamming a connection, not hijacking it - it disrupts the link rather than taking it over
• Option B (-c any) is a sniffing/scanning command used to discover and capture new BLE connections passively
• Option C (-d /dev/ttyACM0 -d /dev/ttyACM2 -s) uses multiple device interfaces with the -s flag for sniffing across multiple micro:bit hardware devices simultaneously

Memory Tip: Think "-t = takeover" - the -t flag in Btlejack stands for the takeover (hijack) function. If you remember that hijacking = taking over = -t, you can quickly eliminate other commands that involve scanning (-c), sniffing (-s), or jamming (-j).
