CYBER SECURITY CHALLENGES IN 2023

While certain cyber threats remain consistent over time, others fluctuate in prominence. In 2023, businesses should be ready to confront several notable cybersecurity challenges. These challenges may include:

Ransomware Extortion

Ransomware has evolved from encrypting data for extortion to incorporating data theft as well. Initially, attackers encrypted data and demanded ransom for its recovery. However, security research and backup practices have made it possible to save data and restore systems without paying a ransom. In response, cybercriminals introduced double extortion attacks, combining data encryption with data theft. Some ransomware operators now focus solely on data theft, skipping encryption altogether. These attacks are quicker, harder to detect, and cannot be resolved through backups, posing a greater threat to businesses. As a result, businesses must remain vigilant and adopt comprehensive security measures to protect against this evolving form of ransomware extortion.

Wipers and Destructive Malware

Wipers and Destructive Malware pose a severe threat to corporate data security, surpassing the impacts of ransomware and data breaches. Unlike ransomware, wipers don't hold data hostage but rather completely erase it. While wipers have been infrequent in the past, their prevalence surged in 2022. Multiple wiper variants were created and utilized in cyberattacks targeting Ukraine amid its conflict with Russia. Other nations, such as Iran and Albania, have also fallen victim to destructive cyber assaults, signifying the increasing adoption of these techniques for hacktivism and cyberwarfare. This resurgence highlights the urgent need for robust cybersecurity measures to safeguard against the devastating consequences of wiper attacks.

Cloud Third–party Threats

As companies embrace cloud computing, they face security challenges, particularly regarding third-party threats. Cloud environments can be more vulnerable due to factors like unfamiliarity with cloud security practices and the shared security model. While cybercriminals already target cloud infrastructure, a concerning trend is a focus on Cloud Service Providers (CSPs). By attacking CSPs and their solutions, attackers can potentially access customers' sensitive data and IT infrastructure. Exploiting the trust relationship between organizations and their service providers enables attackers to amplify the scale and impact of their attacks. This highlights the importance of robust security measures and diligent vetting of cloud service providers to mitigate the risks associated with third-party threats in the cloud.

Zero-day vulnerabilities in supply chains

Zero-day vulnerabilities present a significant but temporary risk to corporate cybersecurity. A vulnerability becomes a zero-day when it is discovered, but no patch or fix is available yet. Cybercriminals exploit these vulnerabilities during the period between discovery and the release of a patch, unhindered by any defence measures. Even after patches are released, businesses often delay their implementation for various reasons like resource constraints, security visibility, or prioritization.

One area of particular concern is the software supply chain, where zero-day attacks and unpatched vulnerabilities can have severe consequences. Many companies lack complete visibility into the third-party or open-source code used in their applications. If these external libraries contain unpatched vulnerabilities, cybercriminals can exploit them to target the organization. Moreover, widely-used but vulnerable libraries create potential attack vectors that can be exploited against multiple organizations. Businesses need to address these vulnerabilities promptly and implement robust security measures to protect their software supply chains.

ESSENTIAL CYBER SECURITY BEST PRACTICES TO PREVENT BREACHES

Implementing robust cybersecurity best practices is crucial for preventing breaches and enhancing overall cybersecurity. Here are some top practices to consider:
