Supplementary Case Studies

补充案例分析

Double Agent Operations (WWII)

The British Double Cross System turned every German spy in Britain into a double agent. These agents fed disinformation back to Germany, including false D-Day landing locations. Germany's own intelligence network became its greatest liability.

英国的"双十字系统"将每一个在英国的德国间谍变为双重间谍。这些间谍向德国传回虚假情报，包括假的D日登陆地点。德国自己的情报网络变成了最大的负担。

Competitive Intelligence Countermeasures

Companies that discover corporate espionage sometimes feed false information back through the same channels rather than shutting them down. The disinformation campaign can mislead competitors about product roadmaps, pricing strategies, or launch dates.

发现商业间谍活动的公司有时通过相同渠道回馈虚假信息，而非关闭通道。虚假信息行动可误导竞争对手的产品路线图、定价策略或发布日期。
