Digital Predators of 2023: Exposing Top Cyber Threat Actors

In 2023, the digital landscape continued to evolve rapidly, but so did the sophistication and audacity of cyber threat actors. From ransomware to sophisticated phishing campaigns, the threat landscape has been dominated by groups that have advanced their technical capabilities and expanded their targets globally. This introduction provides a glimpse into the most dangerous threat actors of the year, each with their distinct methods and significant impacts across various sectors. Their activities underscore the importance of staying vigilant in cybersecurity and understanding the evolving threats in the digital world. For a comprehensive review of last year’s threat landscape, SOCRadar’s 2023 End-of-Year Report offers detailed insights into these and other topics.

CLOP Ransomware

The CLOP Ransomware group came to the fore in 2023 with the GoAnywhere and MOVEit attacks.

The CLOP Ransomware, known for its involvement with the CryptoMix family, has been a significant cyber threat since 2019. Its evolution includes targeting large organizations and exploiting vulnerabilities like the zero-day in GoAnywhere MFT, Fortra’s secure file transfer solution. In 2023, CLOP made headlines for adopting torrents to distribute stolen data, enhancing their extortion tactics. This change in strategy indicates a shift to more accessible and efficient data dissemination methods, making it harder for law enforcement to intervene. CLOP has targeted various sectors, including finance, IT, and manufacturing, focusing particularly on Western countries like the US, UK, Canada, and Germany.

LockBit 3.0 Ransomware

Play Ransomware, active since mid-2022, has demonstrated a significant threat in 2023 with its advanced techniques and broad targeting. It gained attention for its unique intermittent encryption method, enhancing evasion. Key attacks included significant breaches at a Swiss IT firm affecting government entities, a major Spanish bank, and a U.S. communications firm. The group also shifted to a Ransomware-as-a-Service (RaaS) model, indicating a potential increase in future incidents due to the ease of deployment for other threat actors.

Rhysida Ransomware
