Short Answer 
To identify potential espionage in coworkers, watch for suspicious behaviors such as taking classified materials home, unauthorized downloads, and unreported contacts with foreign nationals. Additionally, assess emotional indicators like employee dissatisfaction and unexplained wealth, along with monitoring red flags such as concealed foreign travel and unusual work hours.
Step 1: Identify Suspicious Behaviors
To recognize potential espionage indicators in a coworker, observe their behavior carefully. Key actions to look for include:
- Taking classified material home: This is a direct violation of protocols and poses a significant threat of information leaks.
- Unauthorized downloads: Downloading sensitive materials without permission can indicate malicious intent.
- Unreported contact with foreign nationals: Interactions with individuals outside of work related to foreign entities may suggest suspicious activities.
Step 2: Assess Emotional and Behavioral Signals
An employee’s emotional state can also provide insights into potential espionage. Look for signs such as:
- Disgruntled employee: Employees showing dissatisfaction may be more inclined to participate in disloyal activities.
- Seeking unnecessary access: Attempting to obtain information that is not relevant to their role can indicate ulterior motives.
- Unexplained affluence: Sudden wealth without evident sources may imply compensation for sharing sensitive data.
Step 3: Monitor Additional Red Flags
Besides behaviors and emotions, pay attention to other unusual patterns that could indicate espionage. These can include:
- Concealing foreign travel: Not reporting international trips can suggest secrecy and possible dangerous connections.
- Unusual work hours: Working odd hours might allow unauthorized access to critical information.
- Avoiding polygraph tests: Evasion of lie detection can hint at guilt or concealed activities related to espionage.
