Email impersonation to trick users.

Accordingly, these e-mails contain the following content: 'The parcel has been sent to your home, after 3 days you will receive it. Information and receipt number viewed in the attached file '.

When extracting the attached file, users will see .doc text files or .pdf files. However, it is the malicious code hidden under the icon (icon) above files.

Mr. Vu Ngoc Son, Director of Research Department of Bkav (Bkav R&D) said: ' Most computers for default mode do not display the file extension. Moreover, the file's icon is a normal text file, so users are easily fooled. '

Therefore, Bkav recommends that computer users set up a file extension to easily distinguish malicious files.
