JAKARTA - Cyber attacks of the backdoor type against businesses in Southeast Asia continue to increase. Kaspersky security solutions successfully detected and blocked more than 3 million attacks throughout 2025.

Backdoor is one of the dangerous cyber threats because it provides remote administrative access to attackers without the user's knowledge.

Unlike legitimate remote administration utilities, backdoors can be installed and run in stealth mode. Once active, attackers can send or receive files, execute commands, steal sensitive data, and record victim activity.

Geographically, Indonesia and Vietnam accounted for the largest number of backdoor attacks in Southeast Asia, with 1,583,035 and 1,296,924 detections, respectively.

Then followed by Thailand with 251,502 cases, Malaysia with 212,239, Singapore with 50,511, and the Philippines with 35,232 detections.

In addition, Kaspersky also highlighted the increase in backdoor detection year-on-year (YoY). Where Malaysia recorded the highest spike of 86 percent, followed by Indonesia at 36 percent and Vietnam at 3 percent.

Meanwhile, Thailand is relatively stagnant year-on-year, while Singapore and the Philippines have actually experienced a decrease of 49 percent and 35 percent respectively.

Managing Director for Asia Pacific at Kaspersky, Adrian Hia revealed that this increased detection, highlights a critical shift in the threat landscape across Southeast Asia, from "breaking into the system" to "surviving in the system".

"For businesses, this underscores the importance of continuous monitoring, advanced detection, and rapid response capabilities to uncover hidden access and prevent ongoing cyberattacks," said Hia.

Therefore, Hia emphasized the importance for businesses across the region to invest adequately in securing their devices, not only to prevent potential financial and data losses, but also to avoid creating channels for further cybercrime.
