According to CMC Infosec, most infected devices are located in Ha Noi, Ho Chi Minh City and Da Nang, as well as in their neighboring provinces.

In Ho Chi Minh City, ransomware had attacked around 200 devices, mostly web servers, the company said.

“Victimcs of WannaCry in Viet Nam are mostly small and medium enterprises (SMEs) with underdeveloped security alert systems that use pirated versions of Microsoft Windows operating systems,” a CMC Infosec representative said.

“Domain providers, data systems and companies with frequent data sharing and storage activities are among the prime targets.”

WannaCry is a ransomware computer virus that targets the Microsoft Windows operating system.

A global attack was launched last Friday, targeting a huge number of computer systems around the world by encrypting data stored on computers to demand money.

Earlier reports by Bkav, a leading Vietnamese cyber security firm, suggested that up to 52% of computers in Viet Nam were susceptible to the EternalBlue vulnerability found in Windows operating systems.

According to Athena Cyber Security Training Center, a number of Vietnamese firms based in Binh Duong, Dong Nai and Ho Chi Minh City have suffered severe damage through ransomware attacks.
