It has been reported that cyber attackers prefer frequently used file types to deliver malicious software to their targets, and in 2020, malware was sent mostly via ‘.exe’ extension via the web and ‘.doc’ extension files via e-mail.

President of the Presidency Digital Transformation Office Ali Taha Koç made an assessment of the methods used in cyber attacks to the AA correspondent.

“Files from unsure sources should not be downloaded”

Warning that attackers are trying to reach their goals by hiding malicious software in different file types, Koç said, “Cyber ​​attackers prefer file types that are frequently used to deliver malicious software to their targets. In 2020,” .exe “is the most on the web and the most via e-mail. Malware was sent via files with a .doc “extension.” he spoke.

Emphasizing that it is necessary not to download files from unsure sources in order to protect against malicious software included in these frequently used file types, Koç stated that it should be checked whether the file type to be downloaded is suitable for the purpose of use and that the size should not be larger or smaller than necessary.

Koç added that details regarding the measures to be taken in this regard can be found in the “Information and Communication Security Guide”.
