The organization has been struggling with the consequences of a ransomware attack for several days.
Vietnam's state postal service has restored its services after several days of downtime caused by a cyberattack. On June 4, Vietnam Post was attacked using a cryptographer, which affected the work of postal and courier services. At that time, the company reported that its financial, administrative and commodity distribution services were not affected by the attack.
According to local media reports, Vietnam Post worked with government agencies and local cybersecurity experts to localize the incident, protect customer data, and restore its systems. Upon discovering the incident, the company contacted the country's security authorities and shut down its IT system to contain the leak. Vietnam Post did not disclose who it considers responsible for the attack or whether the hackers demanded a ransom.
This is not the first time that the postal service has been subjected to cyber intrusion. Last November, researchers discovered that the company had left its security logs and employee email addresses accessible to external users. The researchers also found an open Kibana Vietnam Post visualization dashboard used for data retrieval and analytics. At the time of detection, the data contained 226 million registered events, which is 1.2 terabytes of data that was updated in real time. The data was available for at least 87 days, making the company vulnerable to cyber threats.
According to local security officials, Vietnam is experiencing an increase in cyber attacks, especially those that use cryptographers. Last year, more than 13,900 cyber incidents were registered in the country-almost 10% more than a year earlier, according to Vietnam's National Cyber Security Center (NCSC). Hackers mainly target government agencies, banking services, financial institutions, and industrial systems.
Since late March, Vietnam has seen at least three large - scale data encryption attacks targeting large companies, including VnDirect, one of the largest brokerage houses, gasoline retailer PVOil, and a local telecommunications service provider.
In April, the country's Prime Minister issued a directive instructing ministries and local government agencies to review and assess the current cybersecurity situation.
