Free WannaCry Checker

The utility developed by Vietnamese companies allows detecting computers infected with ransomware, scanning for devices that have not been patched for security vulnerabilities.

Bkav's WannaCry testing tool.

In response to the spread of WannaCry in Vietnam, Bkav has launched the Malware Scan application for users to scan their computers to see if they are infected with this malware. The tool can also check and warn if the computer contains the EternalBlue vulnerability - the vulnerability that WannaCry exploited to infiltrate the computer.

To use, users download the application to their device. The tool does not need to be installed but can be run immediately to scan, supporting access to the entire computer or each partition and folder. (Download here)

System Scan Utilitycomputer to detect vulnerable devices of Vnist.

Meanwhile, the application of Vietnam Information Security and Communications Technology Joint Stock Company (Vnist) supports security testing for large network systems with dozens and hundreds of computers.

According to Mr. Tran Quang Chien, Director of Vnist, to limit becoming a victim of WannaCry, users' computers should be updated with the MS17-010 patch that Microsoft released on March 14, 2017 (KB4012598). This is the vulnerability that the malware uses to spread from one computer to another in network systems.

To prevent the WannaCry malware from infiltrating or spreading, Securitybox security experts recommend that users immediately update Windows operating system patches. In addition, it is necessary to temporarily block the SMB service on the computer, install or update anti-virus software.
