サイバー攻撃

• ローマ字: saibaa kougeki

意味

Cyberattack — a hacking incident targeting companies, government systems, or infrastructure, frequently reported in Japanese news.

サイバー攻撃 combines the English loanword サイバー (cyber) with the native Japanese 攻撃 (attack). As Japan has increased its digitalisation, high-profile cyberattacks on corporations, hospitals, and government agencies have become a staple of news coverage. The term is used both in formal reporting and in casual conversation when discussing data breaches or system compromises. Related buzzwords include ランサムウェア (ransomware) and 情報漏洩 (data leak).

例文

1. また大手企業がサイバー攻撃を受けたってニュースで見た。

3. 政府のシステムへのサイバー攻撃が増えてるらしくて怖い。
