In the ever-evolving landscape of cybersecurity threats, ESET’s latest Threat Report for the period spanning December 2023 to May 2024 paints a stark picture of sophisticated attacks leveraging advanced technologies to target both individuals and organizations worldwide. The report highlights several emerging trends, including the alarming convergence of artificial intelligence with traditional malware tactics.
Infostealers Masquerading as AI Tools
One of the most concerning developments identified in the report is the emergence of infostealers that mimic generative AI tools. Cybercriminals are increasingly leveraging the popularity and trust associated with AI technology to deceive unsuspecting victims. Tools such as Midjourney, Sora, and Gemini, originally designed for creative or predictive purposes, have been exploited by malware like Rilide Stealer and Vidar. These malicious actors use the guise of legitimate AI assistants to lure victims into downloading malware under false pretenses.
The Rise of Deepfake-Generating Malware
Another disturbing trend highlighted in the report involves the use of deepfake technology by cybercriminals. The newly discovered mobile malware, GoldPickaxe, represents a significant advancement in malicious capabilities. This malware not only steals sensitive facial recognition data but also utilizes it to create deepfake videos. These videos are then used to authenticate fraudulent financial transactions, allowing attackers to bypass security measures that rely on biometric verification.
Jiří Kropáč, Director of ESET Threat Detection, underscores the global reach and adaptability of these threats, noting that GoldPickaxe and its predecessor, GoldDiggerPlus, have targeted victims across Southeast Asia, Latin America, and South Africa. This underscores the malware’s sophisticated approach in exploiting regional-specific apps and vulnerabilities.

Targeted Attacks and Regional Campaigns
The report also highlights specific instances of targeted attacks and regional campaigns observed during the first half of 2024. RedLine Stealer, for example, experienced multiple detection spikes across various regions, including Spain, Japan, and Germany. This infostealer primarily targeted gamers through cracked video games and cheating tools used in online multiplayer environments. Similarly, Lumma Stealer and other malware variants were discovered embedded within popular gaming utilities, further emphasizing the growing intersection of gaming and cybersecurity threats.
WordPress Vulnerabilities and Web Compromises
In addition to malware targeting end-users, ESET’s telemetry revealed ongoing exploits of content management systems, particularly WordPress plugins. The Balada Injector gang, notorious for exploiting such vulnerabilities, compromised over 20,000 websites in the first half of 2024 alone. These compromises not only highlight the persistent vulnerabilities within widely used web platforms but also underscore the scale at which cybercriminals operate to exploit them.
Ransomware and Server-Side Malware
The report also addresses the evolving landscape of ransomware, with notable mentions of Operation Chronos’s disruption of the LockBit ransomware gang earlier in 2024. Despite this disruption, ESET telemetry recorded continued incidents attributed to non-LockBit groups using the leaked LockBit builder. Additionally, the report features an in-depth investigation into the Ebury group, a sophisticated malware and botnet operation targeting Linux, FreeBSD, and OpenBSD servers. The group has compromised nearly 400,000 servers over the years, demonstrating the persistent threat posed by server-side malware.
Looking Ahead: Future Threats and Mitigation Strategies
Looking forward, ESET experts anticipate further innovations in malware tactics, with AI-driven attacks likely to become more prevalent. As cybercriminals continue to exploit emerging technologies and vulnerabilities, organizations and individuals must remain vigilant and adopt robust cybersecurity measures. Proactive threat detection, regular software updates, and user education remain critical components of effective cybersecurity strategies in combating these evolving threats.
In conclusion, the ESET Threat Report for mid-2024 serves as a timely reminder of the evolving nature of cybersecurity threats and the urgent need for enhanced defenses against sophisticated malware operations. As technologies continue to advance, so too must our defenses to safeguard against the ever-present dangers of the digital age.
