[Case] Indonesian data breached in hacking forum

→ Indonesian hackers and Indonesian investigative agencies began to search Bjorka’s information to track him, and during the process, a few Indonesian hackers showed disrespectful behavior to other users.

→ In response, hacking forum users supported ‘Bjorka’ by actively leaking Indonesian data and documents, and as a result, more than hundreds of Indonesian data leaks occurred in the forum alone in one month.

The media is reporting this issue every other day, and Bjorka is still maintaining his online activities by creating his own Twitter account and Telegram channel.

→ The Indonesian parliament has proposed a law to strengthen privacy and finally passed the enactment on September 20th. However, in order to establish strong cyber security, many experts suggest it is necessary to
establish an infrastructure and secure good manpower in addition to the law.

S2W Suggestion

  1. Set up an IoC (Indicators of Compromise) and derive TTP (Tactics Techniques and Procedure) through incident response
  2. Establish an active monitoring system for anonymous channels (dark web, forums, telegram, etc.) for early detection of incidents and data leaks
  3. Implement cyber threat removal activities through profiling system for threat actors and monitoring system for Initial Access Broker (IAB) Market
  4. Trace criminal money flows and attribute threat actors through international cooperation, and unveil the association among threat actors, money and incidents
  5. Execution of active cyber-crime deterrence action against threat actors through national-level Defend Forward activities
