✅ Report Title: Threat Group Profiling: RipperSec

✅ Executive Summary:

📌 Who Is the RipperSec Group?

- RipperSec is a Malaysian pro-Palestinian and pro-Islamic hacktivist group.

- RipperSec, primarily based on Telegram, has been conducting cyberattacks against multiple countries while demanding an end to military support for Israel and advocating for the liberation of Palestine.

- It cannot be ruled out that these groups may engage in serial targeting whenever official positions on international conflicts are announced, joint responses with allies are initiated, or South Korean policy decisions regarding global political issues are made.

📌 Influence Within the Muslim Telegram Ecosystem

- According to the analysis by the S2W Threat Intelligence Center, as of March 2025, RipperSec is evaluated to be among the top 15 most influential channels within the Muslim Telegram ecosystem.

- Telegram channels that use languages from 39 Muslim-majority countries are defined as 'Muslim Telegram channels.'

📌 Attack Patterns

- They primarily carry out DDoS attacks and attacks on SCADA systems.

- Given the current attack patterns, short-term service disruptions, website access failures, and reputational damage pose greater risks than large-scale data exfiltration.

- Based on collaborative relationships with other hacktivist groups, RipperSec conducts DDoS attacks against various countries and expands the number of participants by lowering the barrier to entry through the provision of dedicated attack tools designed for easy use even by users with low technical proficiency.

- As members from various countries unite for hacktivism, organizational scale and attack frequency continue to rise; consequently, both the actual scale of damage and the level of influence are gradually expanding, leading to a heightened potential threat.

📌 What Tools They Use

- The tools MegaMedusa, Zeus Stresser, and JINBEI DDoS Tool were utilized in the DDoS attacks targeting South Korea from February 2026.

1) Mega Medusa

- A DDoS attack tool created by a developer belonging to RipperSec, MegaMedusa was previously released, shared, and updated through GitHub; however, due to strengthened account controls and content removal measures on GitHub, file distribution and update information are currently shared primarily through Discord channels.

2) Zeus Stresser

- Zeus Stresser is a commercial DDoS-as-a-Service infrastructure that manages announcements and updates through the Telegram channel ‘ZeusAPI News/消息’;

  - once a target is shared within the community, multiple users simultaneously access a web panel to execute L7 based DDoS attacks.

- Zeus Stresser is not an attack infrastructure developed internally by RipperSec, but rather a strategic utilization of a commercially available DDoS service operating externally.

📌 Why Do They Attack South Korea

- (2026-02-05) RipperSec selected South Korea as an attack target after sharing foreign news reports (News1, News2) alleging that South Korea exported approximately $599 million worth of weapons to Israel in 2024, claiming that South Korea is indirectly contributing to Israeli attacks on Palestine.

  - RipperSec conducted DDoS attacks against South Korea in 2025 for the same reasons and mentioned the need for additional attacks, suggesting that the scale of the previous attacks was insufficient.

- (2026-02-14) Through the South Korea Operation statement, RipperSec announced that this operation could continue until the South Korean government completely stops providing weapons, bombs, and tanks to Israel, signaling a prolonged conflict.
