Must Know! Types of Cyber Threats in Indonesia that Attack Companies

In the current digital era, cyber-attacks are becoming an increasingly worrying threat. In Indonesia, large and small companies are easy targets for cybercriminals. So, understanding the types of cyber threats is necessary for every company.

The Importance of Understanding Types of Cyber Threats

Knowing and understanding cyber threats in Indonesia is the first step in building a robust cyber defense. Companies can identify potential risks and implement appropriate security strategies with this understanding.

Types of Cyber Attacks Targeting Corporations in Indonesia

From attacks aimed at stealing data to those that result in financial loss, various types of cyber threats lurk. In the next section, we will discuss in more detail the types of cyber threats that often attack companies in Indonesia.


Malware is a malicious program created to cause damage or access a system without permission. Some types of malware include viruses, worms, and trojans.


Phishing is a tactic of obtaining personal data by pretending to be a trusted institution or individual, often via email or other forms of communication.


Ransomware is a type of malware that encrypts the victim’s data and demands a ransom to return the data.

Man-in-the-Middle Attack

In this attack, the perpetrator intercepts communications between two parties to steal or manipulate information.

Denial-of-Service Attack (DoS)

DoS is an attempt to make computer or network resources unavailable to authorized users.

Distributed Denial-of-Service Attack (DDoS)

Similar to DoS, DDoS involves multiple computer systems to attack one target.

SQL Injection

This technique exploits weaknesses in a database application to gain access to the database.

Cross-site Scripting (XSS)

XSS is an attack in which a malicious script is inserted into a web page and executed by another user.

Zero-day Attack

This attack exploits a software weakness that is not yet known to the public and does not yet have a patch.

Impact of Cyber Attacks

Financial Loss

Cyberattacks can cause significant financial losses to companies, either directly or indirectly, through business losses or lawsuits.

Reputational Damage

Cyber-attacks can destroy a company’s reputation that has been built over years in a short time.

Data Loss

Data stolen or encrypted by ransomware can be an irreplaceable loss.

Operational Disruption

Cyber-attacks can halt business operations, causing production or sales losses.

How to Protect Yourself from Cyber Attacks

Adequate Cybersecurity Implementation

Companies must implement firewalls, antivirus and other security solutions.

Employee Education on Cybersecurity

Employees should be trained on how to identify and avoid threats.

Carrying out Cyber Attack Simulations

Simulations can help a company understand how strong its defenses are.

Cyber Attack on BSI Bank

On May 8, 2023, Bank Syariah Indonesia (BSI) experienced service disruption for several days. The disorder was caused by a ransomware cyber-attack from hackers who called themselves the LockBit Ransomware Group.

This cyber-attack succeeded in gaining access to BSI’s computer system and encrypting customer data. The attacker then demanded a ransom of 70 million US dollars to return the data.

BSI refused to pay the ransom and switched off temporarily to restore its system. The BSI service disruption impacted customers, who could not carry out banking transactions for several days.

After this cyber-attack, BSI has taken steps to improve its systems’ security. These steps include:

  • Conduct investigations to identify security vulnerabilities exploited by attackers.
  • Improve system security by applying the latest patches and updates.
  • Increase employee security awareness to prevent future cyber-attacks.

The cyber-attack on BSI is an essential lesson for the banking industry in Indonesia. This attack shows that the Indonesian banking system is still vulnerable to cyber-attacks. Therefore, more serious efforts need to be made to improve the security of the banking system.

The following are several steps that banks can take to improve the security of their systems:

  • Make adequate investments in cybersecurity.
  • Establish a competent and trained cyber security team.
  • Conduct regular security evaluations to identify and fix vulnerabilities.
  • Increase employee security awareness to prevent cyber-attacks.
