Blue bomb is a slang term for a specific kind of denial of service attack that results in a blue screen of death, a Windows operating system screen showing that the system has crashed. A blue bomb is also known as WinNuke, and it involves sending an out-of-band packet that the operating system is not able to process.
Techopedia Explains Blue Bomb
Blue bombs started with early versions of the Windows operating system, such as Windows 95 and Windows NT. It was often used by game players and IRC chat participants, and was easily sent to other computers to crash a system. The blue bomb sent an “urgent pointer” which the operating systems did not handle correctly. It attacked a computer through port 139.
Over time, Windows released patches and addressed the problem with blue bombs. Later in the early years of the millennium, experts suggested that a new version of WinNuke was affecting systems such as Windows 2000 and XP. The new version used port 139 as well as port 445. Windows also sent patches for this version. In addition, Internet service providers began to find ways to disrupt the transmission of these destructive packets.
