Cybercriminals are continually developing new methods to exploit vulnerabilities, and even the most tech-savvy individuals and organizations can find themselves at risk. While some cyberattacks like phishing and malware are well-known, several lesser-known but equally dangerous threats require attention. This blog post explores six types of cyberattacks you might not have considered but should be on your radar.
1. Botnet Attacks
A botnet attack involves a network of compromised computers, or "bots," which are controlled by a single entity, often referred to as a "botmaster." These botnets can be used to launch large-scale cyberattacks such as Distributed Denial-of-Service (DDoS) attacks, which overwhelm a target’s resources, rendering it inaccessible.
In 2016, hackers used the Mirai botnet to take control of millions of devices and launched a huge DDoS attack on Dyn, a major domain name server provider.
Some hackers also take over IoT devices to "brick" them, which means they damage the device’s firmware so it becomes useless. They do this for fun or to teach people about cybersecurity.
2. LLMjacking
As language models become integral in various applications, they present new cyberattack vectors. LLMjacking, or Large Language Model hijacking, involves manipulating language models to generate harmful or misleading information.
Attackers can exploit vulnerabilities in these models to spread misinformation, influence public opinion, or even automate phishing attacks. The rise of AI-powered tools necessitates the implementation of stringent security measures to safeguard against such manipulations.
Companies that utilize cloud-hosted Large Language Models (LLMs) are at risk of LLM jacking because they possess the necessary server resources to operate generative AI programs. Hackers might exploit these resources for personal purposes, such as creating their own images, or for more malicious activities like generating harmful code, contaminating the models, or stealing sensitive information.
While an individual hijacking a cloud-based LLM for personal use might not cause significant damage, the costs associated with resource usage can be substantial. A severe attack could result in charges ranging from $50,000 to $100,000 per day for the owner.
3. Ransomware
Unlike traditional malware that aims to steal information, ransomware directly extorts victims. Attackers encrypt valuable data and demand payment, often in cryptocurrency, for the decryption key. Organizations of all sizes are potential targets, and the financial and reputational damage can be severe. Preventative measures, including regular data backups and cybersecurity training, are crucial in mitigating the risks of ransomware attacks.
4. Insider Threats
An insider threat comes from within the organization, typically from employees, contractors, or business partners who have inside information concerning the organization’s security practices. These threats can be malicious or unintentional but are dangerous due to the privileged access insiders have.
They may misuse their access to steal sensitive information, disrupt operations, or introduce vulnerabilities. Organizations need to implement strict access controls, regular monitoring, and education to reduce the risk of insider threats.
5. Man-in-the-Middle (MitM) Attacks
Man-in-the-middle attacks occur when an attacker intercepts communication between two parties without their knowledge. The attacker can then eavesdrop, manipulate, or steal sensitive information being exchanged.
MitM attacks are particularly concerning for financial transactions and other confidential communications. Encrypted communication channels, strong authentication methods, and educating users about potential risks are effective strategies to prevent such attacks.
6. Phishing Schemes
Phishing remains one of the most prevalent cyber threats, evolving in sophistication and technique. Attackers use deceptive emails, messages, or websites to trick individuals into divulging personal information such as usernames, passwords, and credit card details.
Spear phishing, a targeted form of phishing, involves personalized attacks on specific individuals or organizations, making them harder to detect. Continuous cybersecurity awareness training and employing advanced email filtering solutions can help protect against phishing schemes.
