During the transportation process of the supply chain, thieves may use a variety of hidden means to steal items. The following are some common and complex methods, classified by category.： --- ### **1. Collusion between insiders** -**Means**： -**Falsification of records**: Warehouse or transportation personnel tamper with inventory data or transportation documents to cover up the missing goods. -**Midway sharing of spoils**: The driver deliberately detours during transportation, transfers part of the goods to his accomplices, and then reseal the cargo box. -**False report of loss**: Falsely claiming that the goods are damaged or lost, and actually embezzled and resold on the black market. -**Concealment**: Using job authority and system vulnerabilities, it is difficult to be discovered by external audits. --- ### **2. Technical interference and tampering** -**Means**： -**GPS spoofing**: Use signal jamming equipment to falsify the location of the vehicle to conceal the actual place of stay for theft. -**Sensor tampering**: Destroy the temperature, humidity or vibration sensors to avoid triggering abnormal alarms (such as the theft of cold chain goods). -**Hacking attack**: Invade the logistics management system and delete or modify the cargo tracking information. -**Concealment**: Relying on technical vulnerabilities, there are no anomalies at the data level, and only a professional technical team can identify them. --- ### **3. Physical means and forgery** -**Means**： -**Mezzanine hiding**: Install a concealed compartment in a container or truck to restore the appearance after stealing some of the goods. -**Exchange labels**: Replace the labels of high-value goods with low-value products to mislead the recipient for acceptance. -**Imitation seal**: Use a high imitation seal or lock, reseal it after theft, and pretend to be unopened. -**Concealment**: Relying on rapid operation and visual deception, routine inspections are difficult to detect. --- ### **4. Transportation process exploit** -**Means**： -**Midway interception**: Pry open the carriage at a rest stop or a remote section of the road to steal the goods (such as the “dump” technique: part of the goods are left behind during high-speed driving and picked up by the accomplice). -**False transshipment**: Forged transshipment instructions to guide the goods to a non-cooperative warehouse for distribution of the spoils. -**Empty box exchange**: During sea or rail transportation, replace fully loaded containers with empty boxes (port/station personnel need to be colluded). -**Concealment**: Taking advantage of the complexity of the transshipment link, theft is blamed on process errors. --- ### **5. File and information fraud** -**Means**： -**Forged bill of lading**: The goods are picked up in advance through false identities or documents. -**Duplicate bill of lading**: Use the loophole in the document to sell or transport the same batch of goods multiple times. -**False insurance claims**: Insiders of the United Insurance company falsely reported the loss of the goods to obtain compensation for fraud. -**Concealment**: Relying on asymmetric information in all aspects of the supply chain, fraud may not be discovered until several months later. --- ### **6. Social engineering attack** -**Means**： -**Disguise your identity**: Pretend to be a customer, customs officer or logistics employee to defraud the delivery authority of the goods. -**Bribing key personnel**: Buying security guards, quality inspectors, etc. to relax inspections or provide cargo information. -**Concealment**: Using interpersonal trust, it is difficult to track through technical means. --- ###**Preventive advice** -**Technology upgrade**: Use BLOCKCHAIN to track the whole process of goods and deploy tamper-proof Internet of Things devices. -**Process control**: Implement double acceptance, random route planning, and regularly audit inventory and transportation records. -**Personnel screening**: Strengthen the background check of internal personnel and implement hierarchical management of authority. -**Partner review**: Strictly screen logistics service providers to ensure their safety and compliance. The concealment of supply chain theft often depends on system vulnerabilities and personnel negligence, so it is necessary to reduce risks through multi-dimensional prevention and control.
