In July 2015, a large-scale cyber attack occurred in mainland China, which is known as the 327 incident. This incident involved several provinces and industries and caused considerable impact. In this article, we will introduce the details of the 327 incident, its impact and preventive measures.
The incident
According to reports, the 327 incident was a cyber attack using ransomware as a means. The attacker sent an attachment with a Trojan horse virus to the victim via email or other means. When the victim opened the attachment, the Trojan virus began scanning and encrypting operations on the victim's computer, eventually encrypting the files and extorting ransom from the victim.
According to statistics, the 327 incident involved a large number of victims from a variety of industries, including government agencies, finance, energy, telecommunications, and healthcare. The attackers demanded that victims pay bitcoin as ransom, ranging from a few hundred dollars to tens of thousands of dollars.
Impact
The 327 incident posed a huge threat to cybersecurity in mainland China. Many businesses and organizations were paralyzed after the incident. Victims' data was encrypted and could not be used normally, causing considerable financial losses. In addition, the attackers may also steal sensitive information of the victims, which poses a great threat to personal privacy.
Precautions
In order to avoid the recurrence of similar incidents, we need to take some precautions. Here are some feasible measures:
1. Strengthening network security awareness: Enterprises and organizations should strengthen the network security awareness of their employees and educate them on how to identify spam and malicious attachments.
2. Strengthen network security technology: Enterprises and organizations should strengthen investment in network security technology, update and upgrade network security equipment and software, and patch vulnerabilities in a timely manner.
3. Backup data: Enterprises and organizations should regularly back up their data so that they can quickly recover it if it is encrypted.
4. Strengthen monitoring: Enterprises and organizations should strengthen the monitoring of the network, timely detection of abnormalities and take measures.
