During the January-June period, the amount of data encrypted by attacks reached 3 Terabytes with a total estimated loss of more than 10 million USD. Many attacks were reported in various fields such as finance, public services, information technology, and manufacturing.
Viettel Threat Intelligence recorded that 56 organizations in these fields were initially attacked with ransomware but had not had their data encrypted. In addition, there were about 500,000 DDoS attacks, a year-on-year increase of 16%.
Viettel Cyber Security (VCS) company recommended that organizations and businesses review backup systems, ensuring that backup data is physically and logically separated from the main systems, and can be recovered when the main system is under attack.
Businesses should tighten access rights and manage servers and access control systems, add multi-factor authentication mechanisms for key systems and accounts, and regularly update patches for internet-facing applications. It is essential for them to pro-actively grasp information about cyber attack incidents and trends to take the initiative in handling and ensuring information security, VCS added.
