Trends and Patterns
Ransomware, a costly and adaptive threat, continues transforming alongside technological advancements. To grasp the evolving ransomware landscape in 2023, it’s crucial to identify key trends and patterns that shape its tactics. Reflecting on the trends of 2022 and looking ahead to 2023, here are six notable evolutions and three predicted trends by security researchers that shed light on the ever-changing nature of ransomware attacks.
Shifting Focus to Data Extortion: Ransomware groups have discovered success in extorting victims by posting stolen data online when their demands are not met. This tactic puts additional pressure on organizations to comply, as the potential exposure of sensitive information can lead to reputational damage and legal consequences.
Exploiting Data Monetization Opportunities: Stolen data is valuable to its rightful owners and to cyber criminals who can sell it to other malicious actors, creating an underground market. The rise of cryptocurrencies facilitates anonymous transactions, making it easier for ransomware groups to profit from their illicit activities.
Targeting Cloud Environment: With the growing adoption of cloud technology, ransomware groups are exploiting vulnerabilities in cloud resources. They use compromised instances for activities for launching ransomware attacks. Cloud environments’ decentralized and interconnected nature provides new attack vectors for cybercriminals.
Expanding Scope to Uncommon Platforms: Ransomware groups now target business-critical devices and platforms that lack readily available backups, increasing the potential impact of their attacks. Linux, Windows, macOS, FreeBSD, and non-standard processor architectures are all fair game, as demonstrated by the emergence of new ransomware families like RedAlert/N13V and LockBit.
Embracing Automation for Scaling Up: Ransomware groups leverage automation to streamline attacks, reducing costs and increasing operational efficiency. Automated tools enable attackers to propagate malware faster, target multiple platforms simultaneously, and evade detection by security systems. In addition, new ransomware strains have even increased encryption speeds enormously.
Leveraging Zero-Day Vulnerabilities: Adversaries take advantage of unknown software flaws or system vulnerabilities, enabling multiple attacks before patches or fixes are developed. This approach allows ransomware groups to exploit security gaps, making it challenging for organizations to defend against attacks effectively.
Looking ahead to 2023, three additional trends are predicted to shape the ransomware landscape:
Enhanced Functionality: Ransomware groups will continue to develop self-spreading capabilities, expanding their reach. Malware can autonomously infect vulnerable systems by incorporating worm-like features, enabling rapid proliferation and increased infection rates.
Driver Abuse: Vulnerable drivers, particularly in antivirus software, will be exploited by malicious actors. Attackers will focus on compromising device drivers to bypass security measures, rendering traditional defense mechanisms less effective and facilitating successful ransomware attacks.
Code Adoption: Ransomware groups will adopt code from other families, enhancing their capabilities and attracting more affiliates. This trend reflects the industrialization of ransomware, where malicious actors collaborate, share resources, and leverage the expertise of different groups to create more sophisticated and potent attacks.
Most Common TTPs of 2023
TTPs are also changing and varying every year in line with the trends. By examining the trends and insights from 2023, we can identify the top 5 TTPs commonly used by ransomware groups. These TTPs shed light on the evolving strategies employed by threat actors to maximize their impact and financial gains. Let’s delve into the details:
- Phishing Campaigns (T1566) Ransomware groups continue to rely on phishing campaigns to gain initial access to target networks. By sending deceptive emails or messages, they trick unsuspecting users into clicking on malicious links or downloading infected attachments. Vigilance and employee awareness training are crucial in mitigating the risks associated with these phishing attempts.
- Exploiting Remote Desktop Protocol (RDP) (T1021.001), Ransomware groups exploit weak or misconfigured Remote Desktop Protocol (RDP) connections to gain unauthorized access to systems. Once inside, they can move laterally across the network, escalating privileges and deploying ransomware payloads. Properly securing RDP by implementing strong passwords, multi-factor authentication, and limiting access can reduce the attack surface significantly.
- Software Vulnerabilities (T1203) Exploiting software vulnerabilities remains a favored TTP among ransomware groups. They target unpatched or outdated software, utilizing known vulnerabilities to gain a foothold in the target environment. Timely software updates and regular vulnerability assessments are vital for minimizing the risk of successful ransomware attacks.
- Supply Chain Attacks (T1195) Ransomware groups increasingly target supply chains, compromising trusted third-party vendors or software providers to gain access to their client’s networks. By exploiting vulnerabilities in the software supply chain, threat actors can infiltrate multiple organizations through a single entry point. Strengthening supply chain security, including conducting due diligence on vendors and assessing their security practices, is essential for mitigating this risk.
- Living-off-the-Land Techniques (T1218) Ransomware groups often employ “living-off-the-land” techniques, utilizing legitimate tools and processes already within a compromised network to carry out malicious activities. This approach allows them to bypass traditional security defenses and remain undetected for extended periods. Monitoring for suspicious behavior, employing behavioral analysis, and implementing robust endpoint detection and response (EDR) solutions can aid in detecting and stopping these stealthy attacks.
The prevalence of ransomware attacks in 2023 highlights the pressing need for organizations and individuals to prioritize robust cybersecurity measures. It is crucial to implement comprehensive security protocols, including regular software updates, strong password practices, network segmentation, and employee training on identifying phishing attempts and other common attack vectors.
