Malware Remains Most Popular Attack Method

The identity and access management (IAM) field is always changing, and staying on top of the latest news, threats, and solutions can help protect yourself and your business from vulnerabilities. In the IAM risk landscape, malware continues to be one of the most popular attack methods to steal credentials for accessing systems.

Malware Attack

A malware attack refers to the intentional deployment of malicious software (malware) by an attacker with the goal of compromising the security or functionality of a computer system, network, or device. Malware is a broad term that encompasses many types of malicious software, such as viruses, worms, trojans, ransomware, spyware, and adware.

During a malware attack, the attacker typically delivers the malware to the target system through various means, such as email attachments, malicious websites, infected software downloads, or compromised networks. Once the malware infects the target system, it can execute its malicious activities, which can include:

1. Unauthorized Access: The malware may grant unauthorized access to the attacker, enabling them to control the compromised system remotely and carry out further malicious actions.
2. Data Theft: Some malware is designed to steal sensitive information such as login credentials, financial data, or personal information from the infected system, which can then be used for identity theft, fraud, or other malicious purposes.
3. System Disruption: Malware can disrupt the normal operation of a system by causing crashes, freezing, or slow performance. This can result in loss of productivity or even system downtime.
4. Ransomware: This type of malware encrypts files on the infected system, rendering them inaccessible to the user. The attacker then demands a ransom payment in exchange for decrypting the files.
5. Botnets: Malware can transform the infected system into part of a larger network of compromised computers, known as a botnet. The attacker can control the botnet and use it for various malicious activities, such as initiating Distributed Denial of Service (DDoS) attacks or sending spam emails.

Preventing malware attacks requires a combination of security measures, including using up-to-date antivirus software, regularly patching and updating systems, being cautious of suspicious emails or websites, and practicing good cybersecurity hygiene. We will cover these and others in the next sections.

Malware Remains Most Popular Attack Method

According to new research, while the frequency of malware attacks has dropped, attacks involving compromised credentials have increased.

Malware is still the most popular form of cyberattack and can be used to steal credentials for use in more sophisticated or extensive breaches. Targeted attacks executed for the purpose of extorting money from companies or stealing valuable data are still common, meaning you need to be diligent across departments in your company. A single phishing email, compromised file, or infected employee device can provide an open door for hackers to undermine your IAM framework.

Malware Statistics

The global malware market share has grown significantly from $7 billion in 2022 to almost $10 billion in 2023. It is expected that the malware market will reach $61 billion by 2030.
