Year after year, global cyberattacks continue to rise dramatically, driven by a variety of forces including digital transformation, remote working, and new technologies. In addition to the increase in volume, we also notice a greater novelty and sophistication in cyberattacks, especially those targeting businesses.

If you have read any news articles or press releases about data breaches, you likely have noticed the generous use of the statement: “We were victims of a sophisticated cyberattack”. How sophisticated are cyberattacks getting? And, what can we learn by looking at the patterns and trends in cyberattacks over the past few years? After all, information is your best weapon against cyberattacks.

This blog post discusses notable examples of novel and sophisticated cyberattacks that are being used to target businesses.

Notable Examples Of Novel And Sophisticated Cyberattacks

Supply chain attacks are a type of cyberattack that targets an organization by compromising the system of its suppliers, vendors, or partners. 

Here’s how Supply Chain Attacks work:

Attackers identify and exploit vulnerabilities of a target organization’s suppliers, vendors, or partners, who may have weaker cybersecurity measures compared to the ultimate target. By targeting the vendors or partners, the attackers aim to steal credentials that will allow them to gain access to the target organization’s systems. Once inside, the attackers can escalate privilege, exfiltrate data, or carry out further attacks.

Supply chain attacks can be launched using a variety of attack vectors, including injecting malicious code into software updates, tampering with hardware components, or infiltrating the network of a trusted supplier. Tampering with the software or firmware of products during the manufacturing or distribution process is particularly devastating because it leads to the distribution of compromised software or hardware to a large number of end-users.

Supply chain attacks have become increasingly popular among hackers because a single successful attack allows them to compromise multiple organizations in the supply chain, maximizing the reach of their exploits. Another potential reason is attribution challenges. It is extremely challenging to identify the source of and contain supply chain attacks since the compromise typically occurs several steps away from the ultimate target organization. 

Supply chain attacks became well-known after the SolarWinds attack of 2020. This attack was staged by injecting a backdoor, known as SUNBURST, into the Orion IT update tool. The compromise impacted around 18,000 customers, including major enterprises and government agencies.

Preventive measures such as vetting suppliers and partners, implementing strong access controls, monitoring for unusual activities, and ensuring the integrity of software updates are your best bets for mitigating the risk of supply chain attacks.

A zero-day exploit is a type of cyberattack that takes advantage of a vulnerability in a software, firmware, or application, which the vendor or developer is not aware of. The term “zero-day” refers to the fact that by the time the vulnerability is discovered by the vendor, it is already being exploited by attackers, giving the developers zero days to fix the vulnerability.

Here’s how Zero-Day attacks work:

A hacker discovers a flaw, which is called a Zero-day vulnerability, in a software or application. Once the vulnerability is discovered, they write a piece of code or program to take advantage of the vulnerability or flaw. This is called a Zero-day exploit. Finally, the hackers use the created exploit to attack systems and breach security. This is called a Zero-day attack.

A zero-day exploit exposes the organization to several threats including unauthorized access, loss of sensitive data, espionage, and malware infection, making zero-day exploits particularly dangerous.

Organizations are extremely vulnerable to such attacks because they have no official solution to fix the vulnerabilities. Since the vulnerability is unknown, organizations are powerless until the software vendor releases a security update.

Attackers move quickly to exploit zero-day vulnerabilities because they know that the targeted software or system lacks necessary defenses and is, therefore, susceptible. These attacks also have a higher rate of success since security measures, such as antivirus signatures and intrusion detection systems, are not yet equipped to recognize and stop these specific attacks.

Mitigating the risks associated with zero-day attacks requires a layered approach involving several security measures, including patch management, network segmentation, log analysis, and good cybersecurity practices.

Ransomware attacks are nothing new. I have covered ransomware attacks and how to deal with them in an earlier blog post so I won’t go into it here. You can access it here: How To Deal With A Ransomware Attack. But there have been developments in how these attacks are carried out and these developments present serious security challenges to businesses.

Lately, some ransomware groups have started using a new kind of tactic that combines encrypting ransomware and leakware. This double-extortion tactic involves the exfiltration of sensitive information in addition to data encryption. The attackers then threaten to release the stolen data unless a ransom is paid. This adds pressure on the victim, increasing the chances of ransom payment.

Deepfake attacks refer to the use of realistic fake videos or audio recordings in online scams, frauds, and other cyberattacks. These attacks involve the use of generative AI to create highly realistic fake content, typically in the form of videos, audio recordings, or images that are then used for malicious purposes.

Here’s how Deepfake attacks work:

Attacks use deepfake technology to create fake videos, audio, or images. The technology allows them to manipulate media, including facial expressions, lip movements, voice patterns, and other characteristics to make it appear as though a person is saying or doing something they never did. These manipulations can be convincing enough to deceive viewers into believing that the fabricated content is real.

The attackers use the deepfakes to conduct social engineering attacks, impersonating trusted individuals, such as company executives or colleagues, to manipulate their victims into clicking malicious links, installing malware, or divulging sensitive information.

Preventing deepfake attacks requires detecting deepfake content, which is challenging because deepfake technologies continue to advance while researchers and technology companies are lagging in developing countermeasures and detection tools.

In the meantime, mitigating the risks associated with deepfake attacks falls on the organizations and their employees. Awareness of the evolving landscape of deepfake technology, the use of reliable authentication methods, and a security-conscious culture are currently your best bets for countering deepfake attacks.

AI-powered attacks refer to cyberattacks that use artificial intelligence (AI) and machine learning (ML) techniques to enhance their effectiveness, sophistication, and evasiveness. Attackers can use AI to detect vulnerabilities, automate attacks, optimize various stages of the attack lifecycle, and dynamically respond to security measures. In short, AI-powered attacks include a range of techniques and strategies designed for exploiting vulnerabilities, evading detection, and achieving specific malicious objectives.

Using AI, attackers can automate various aspects of their attacks, from reconnaissance and target selection to the delivery of malware. This enables the attackers to increase the scale and speed of their attacks. AI-powered attacks can also involve the use of adversarial ML techniques to deceive or evade security systems, rendering them less effective in detecting such AI attacks.

However, a less sophisticated use of AI is perhaps the most threatening for businesses. Generative AI such as chatGPT can be used to personalize phishing emails and messages, making them more convincing and increasing their likelihood of success.

Defending against AI-powered attacks is a challenging and continuously evolving field. While a multi-faceted approach using advanced security solutions can help, the ultimate solution lies in the use of the same AI and ML techniques, as used by the aggressors, on the defense side to enhance threat detection, response, and overall resilience.

IoT-based attacks refer to cyberattacks that rely on exploiting vulnerabilities in Internet of Things (IoT) devices and networks. These attacks exploit vulnerabilities in the software, firmware, or configurations of IoT devices to gain access to the device or the entire network.

Once an IoT device is compromised, it can be used for a variety of different malicious purposes, including eavesdropping on communications, unauthorized access to sensitive data transmitted by the device, and using the device as a foothold to attack other systems on the corporate network. Compromised IoT devices can also be enlisted into botnets, which are used to launch distributed denial of service (DDoS) attacks.

Businesses, such as hospitals, hotels, and manufacturing industries, that use a large number of IoT devices are particularly vulnerable to IoT attacks. As the adoption of IoT technology grows, the security challenges in this space require greater attention.

In an earlier blog post, I have discussed the security challenges and best practices associated with IoT devices in great detail. I highly recommend reading it if you are interested in IoT security. You can access it here: How To Secure Your IoT Devices And Infrastructure.

5G technology comes with numerous promises including increased data transfer speeds, lower latency, and support for a massive number of connected devices. But like all technological innovations, 5G also has its share of risks and challenges that businesses need to be aware of.

A greater number of connected devices on an extensive network means the attack surface for potential cyber threats also expands. So, there are more entry points and additional vulnerabilities for attackers to exploit and for organizations to defend.

Additionally, the sheer number of connected devices in a 5G environment makes ensuring robust authentication and authorization extremely challenging. Any lapse in this area can lead to unauthorized access and data breaches.

5G networks are also more likely to be vulnerable to sophisticated Denial of Service (DoS) attacks. Given the high speeds and increased capacity of 5G networks, attackers would be able to generate more significant volumes of malicious traffic to overwhelm the targeted network, leading to service disruptions.

Mitigating the risks associated with 5G networks has to be a team effort, where customers collaborate with service providers, device manufacturers, and technology researchers to develop and adhere to standards and industry best practices. In the meantime. Security measures such as network segmentation, monitoring network traffic, and robust authentication and encryption will help.

Conclusion

Detecting and defending against novel cyberattacks is an onerous task because these threats use new technologies and sophisticated techniques, making it difficult for organizations to defend against them effectively, making it difficult for organizations to defend against them effectively.

Nevertheless, information is an effective weapon when defending against cyberattacks. Keeping up-to-date with the changes in the technology and threat landscapes helps immensely in the timely identification and effective response to cyberattacks, both old and new.
