In office buildings, some criminals may use various tricks to pretend to be maintenance personnel to steal computer equipment. Here are some common tricks and precautions： ### Common tricks： 1. **Falsifying identity**： -**Forged work permits**: Use fake work permits or wear uniforms similar to maintenance personnel to confuse the eyes and ears. -**Fake company name**: Claiming to be from a well-known maintenance company or IT service provider, using the reputation of these companies to gain trust. 2. **Use social engineering**： -**Access to information**: Through conversations with employees, obtain internal information, such as company processes, personnel arrangements, etc., in order to better communicate. -**Create an emergency**: Claim to have an urgent maintenance task, and use the urgency of employees to reduce doubts about their identity. 3. **Distracting**： -**Create chaos**: Create some minor faults or chaos in the office building (such as triggering a fire alarm or making noise), and take advantage of the chaos to enter the target area. - **Collaborative crime**: Multiple people cooperate, one person attracts attention, and the other takes the opportunity to steal equipment. 4. **Use technical means**： -**Forged repair notice**: Send a forged email or notification claiming that equipment maintenance or upgrade is required to enter the office area on this grounds. -**Use of technical tools**: Bring seemingly professional tools or equipment to increase credibility. ### Precautions： 1. **Strict authentication**： -**Verify identity**: Maintenance personnel are required to present a valid work permit and contact their company for verification. -**Appointment confirmation**: All maintenance work should be booked in advance and confirmed by the relevant departments. 2. **Strengthen staff training**： -**Be vigilant**: Educate employees to identify suspicious behavior, especially when encountering maintenance personnel who have not made an appointment. -**Reporting mechanism**: Establish a rapid reporting mechanism to encourage employees to report suspicious persons or activities in a timely manner. 3. **Physical security measures**： -**Access control system**: Install an access control system to ensure that only authorized personnel can enter sensitive areas. -**Monitoring equipment**: Install surveillance cameras in key areas to record all incoming and outgoing personnel. 4. **Information security management**： -**Notification confirmation**: All maintenance notices should be issued through official channels and confirmed by relevant departments. -**Restricted access**: Only maintenance personnel are allowed to access the necessary areas and avoid entering irrelevant areas. By taking these measures, the risk of theft by criminals pretending to be maintenance personnel can be effectively reduced, and the safety of the company's property can be protected.
