Backdoor

Backdoor，電腦病毒木馬，中文名稱—“後門”， 是指在用戶不知道也不允許的情況下，在被感染的系統上以隱蔽的方式運行可以對被感染的系統進行遠程控制，而且用戶無法通過正常的方法禁止其運行。

基本介紹

• 中文名：後門
• 外文名：Backdoor
• 類別：電腦病毒木馬
• 作用：隱蔽的方式對系統進行遠程控制

病毒

註解：繞過安全性控制而獲取對程式或系統訪問權的方法。在軟體的開發階段，程式設計師常會在軟體內創建後門以便可以修改程式中的缺陷。如果後門被其他人知道，或是在發布軟體之前沒有刪除後門，那么它就成了安全風險。

這也有可能是個木馬

清除木馬的步驟：

打開註冊表Regedit

點擊目錄至：

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

刪除右邊的‘c:\windows\notpa.exe /o=yes‘

關閉Regedit，重新啟動到MSDOS系統中

刪除c:\windows\notpa.exe

注意：不要刪除真正的notepad.exe筆記本程式

危害級別：1

說明：

“後門”其實是木馬的一種特例，它們之間的區別在於“後門”可以對被感染的系統進行遠程控制（如：檔案管理、進程控制等）。

下面是英文原義

The act of attacking enemy buildings in their respective base while allied creeps are not inside the base together with the hero(es).

Base: Any building opposed to your side of the team, beginning from the third-line towers protecting the barracks to the Frozen Throne or Tree of Life.

Allied creep(s): Creep(s) generated only by the barracks, and excludes summoned units, i.e. Furion's (Prophet) Forces of Nature, Black Arachnia's (Broodmother) Spawn Spiderlings, Necronomicon's Demon Mages, etc., creep(s) under spell/wiki effect(s), i.e. Aiustha's (Enchantress) Enchant, Chen's (Holy Knight) Holy Persuasion, Helm of Dominator's effect, etc., image(s), i.e. Azwraith (Phantom Lancer), Slithice (Naga Siren), Terrorblade (Soul Keeper), Manta Style effect, etc., and so on.

It is not considered as backdoor as long as there are allied creeps in the base, no matter which lane those creeps were generated from.

Backdooring is allowed IF AND ONLY IF either one of these conditions are fulfilled:

For game(s) which has equal number of players in each team when game started:

The number of players on each team must be the same, e.g. 5v5, 4v4, 3v3.

The team of the backdooring player has a lower number of the opposing team, e.g. 4v5, 3v4, 2v3.

For game(s) which has different number of players in each team when game started:

No number-of-players restrictions apply for backdooring, i.e. Any player(s) can choose to backdoor anytime, anywhere regardless the number of remaining players in the game.

In ANY case, backdooring The Throne/World Tree is not allowed.
