ESET Research and their team of threat detection and research experts have released a comprehensive report on the cybersecurity landscape in the second half of 2023. The report sheds light on significant incidents and emerging trends in the world of cyber threats.
One of the notable incidents during this period was the MOVEit hack by the Cl0p cybercriminal group. This attack, unlike their usual ransomware deployments, involved the theft and potential leakage of sensitive information from various organizations, including global corporations and US governmental agencies. The group’s shift towards leaking stolen data on open web platforms in cases where the ransom was not paid is a concerning trend. This approach has also been observed with the ALPHV ransomware gang, signifying a new strategy in the ransomware landscape. Additionally, the FBI has reported instances of simultaneous deployment of multiple ransomware variants and the use of data wiping techniques following data theft and encryption.
In the realm of IoT security, researchers at ESET made a significant discovery – the existence of a kill switch that effectively rendered the Mozi IoT botnet inoperable. The sudden downfall of Mozi raises questions about the involvement of the botnet creators or Chinese law enforcement in using the kill switch. On a different note, the emergence of the Android/Pandora threat has raised concerns about the compromise of Android devices for DDoS attacks, including smart TVs, TV boxes, and mobile devices.
Another area of focus for ESET Research has been the identification of specific campaigns targeting users of tools like ChatGPT. Instances of attempts to access malicious domains with names resembling “chapgpt” have been observed, highlighting threats to privacy and security. The research team also identified a significant increase in Android spyware cases, particularly linked to the presence of the SpinOk spyware distributed as a software development kit through legitimate Android applications.
The report also sheds light on persistent threats such as the three-year-old malicious JavaScript code JS/Agent, which continues to be loaded by compromised websites, and the ongoing growth of Magecart, a threat targeting unpatched websites for credit card data theft. The increase in bitcoin value has not led to a corresponding rise in cryptocurrency threats. However, there has been a notable increase in cryptostealers, particularly driven by the emergence of the malware-as-a-service (MaaS) infostealer Lumma Stealer targeting cryptocurrency wallets.
The ever-evolving cybersecurity landscape, as illustrated in the ESET Threat Report, reflects the diverse tactics employed by threat actors. The report emphasizes the need for organizations to stay vigilant and implement robust security measures to mitigate these evolving threats.
