Under the epidemic, many companies have implemented work at home, and citizens often shop online. The number of technology crimes has risen accordingly. This year, the first 10 police received 13,163 technology crimes, an increase of more than 20% over the same period last year, and the loss amounted to 2.42 billion yuan.
The Police Cyber Security and Technology Crime Investigation Bureau launched an operation with Interpol to clean up the local network and removed 15 zombie servers. Among them, a private company was implanted with malicious mining programs that made computers become encrypted by hackers without their knowledge. Currency "miners", secretly "mining" for 3 months.
Some scientific and technological experts have reminded that if the home device is found to be operating for a long time and overheating, there is a chance that it has been hacked, and it is recommended to change the password regularly.

After the remittance, the company was notified that it had been deceived and called the police.
The company's servers are implanted with malicious mining programs to increase electricity costs
Senior Superintendent Lin Zhuohao of the Cybersecurity and Technology Crime Investigation Division pointed out that under the epidemic, citizens’ online work, study, shopping and social activities have increased significantly, leading to a corresponding increase in the rate of technology crime. Operation" removed 15 zombie servers with command and control functions, removed 2,486 zombie computers that were manipulated, and discovered 120,000 potentially vulnerable devices.
The police discovered that malicious mining programs were planted on the servers of private companies by criminals who used computer resources to mine secretly for 3 months. "Such malicious programs will reduce computer performance, increase electricity costs, and can seriously bring down the company. System.” Among these zombie computers, Internet of Things devices such as network CCTV cameras, network storage devices, home routers, temperature monitors and photocopiers were also found to be invaded and installed with malicious programs.

The device has been overheated for a long time and may have been invaded
Lin Zhuohao continued that police investigations showed that cyber attacks mainly came from Europe and the United States, which is probably related to the looser registration system of the local network. Hackers use servers in different countries and regions as "springboards" to attack local network systems, and even attack servers in other regions through Hong Kong. Device.
Zhang Guobao, Regional Manager of Kaspersky Lab Hong Kong, pointed out that many citizens will install smart homes. Among them, home video cameras and routers are at the highest risk. Hackers may disclose home images or hack into computers to obtain bank information. If the device overheats for a long time and consumes too much power, the device may be invaded.
Yaniv Hoffman, vice president of Redware Asia Pacific, said that the design of the home contact device lacks security considerations and is easily invaded by the outside world. It is recommended that citizens change passwords and update software regularly.
