Greek companies have the weakest cybersecurity

Greek businesses have emerged as the weakest link in the European Union when it comes to cybersecurity, ranking last in terms of protective measures against cyberattacks. Just days after Kaspersky released data showing that Greece tops the list as the most dangerous online environment globally, Eurostat figures paint a grim picture of corporate cyber-readiness, placing Greek companies extremely low in the rankings.

According to the latest Eurostat data, while the majority of companies in the EU have implemented cybersecurity measures, disparities among member-states remain significant. Greek companies stand out negatively, being labeled as the weakest of Europe in terms of implementing cybersecurity protections.

Beyond 2025

OTS Company, as a partner of the CS-AWARE-NEXT, represented the project at the international digital technology and innovation exhibition “Beyond”, which took place from 4 to 6 of April 2025 in Athens, Greece.

Beyond fosters the development of innovative technologies and business opportunities, while it aims at creating a hub that promotes collaboration and encourages the exchange of knowledge and ideas. It is a great opportunity for global innovators, researchers, and start-ups to connect. This year, the title of the exhibition was “AI Reality Bites” and focused on artificial intelligence and all the factors that come along as it integrates society. Cybersecurity was also a key theme: there were experts who demonstrated live, discussed in panels and showcased in workshops the importance of it and how a user or an organization can be safer online.

Amateur criminals pose a significant threat to cyberspace

Amateur criminals who use do-it-yourself solutions to increase their attacks are now an increasing threat for the internet users. Kaspersky’s GReAT (Global Research & Analysis Team) published a report that describes the recent ransomware attacks with the use of code. The report sheds a light on the tools and the methods that are used by organized ransomware groups and single users. According to its findings the ransomware criminal organisations have a vast variety of tools and samples at their disposal. They often own sample ransomware, while isolated users often use DIY leaked variations to launch their attacks. The study by Kasperksy reveals recent ransomware attacks, which take advantage of the source code leaks, by allowing the attackers to locate their victims and reproduce fast any malware activity, thus constituting them a significant threat. Last April, the SEXi team attacked IxMetro, by using a recent ransomware variation called SEXi. This group targets ESXi apps while all the recognized victims used versions of the apps that were not supported. SEXi uses different ransomware versions for every platform – Bakuk for Linus and Lockbit for Windows. They are, also, the only ones using this Session app for communication, with a unified ID for multiple attacks. This lack of professionalism and the absence of a TOR leak website made them stand out even more.

Information Society is leading the battle for Cybersecurity

The Ministry of Digital Governance (MDG) in Greece is implementing a set of projects through Information Society for the protection of public bodies against cyberattacks.

Cybersecurity in the public sector is crucial for safeguarding sensitive information, ensuring the integrity of essential services, and maintaining public trust. Government agencies handle vast amounts of personal data and critical infrastructure, making them prime targets for cyberattacks. Effective cybersecurity measures prevent data breaches, protect national security, and ensure the continuity of public services. By investing in robust cybersecurity frameworks, the public sector can mitigate risks, respond effectively to incidents, and uphold the privacy and safety of citizens.

New investigation by Kaspersky on Cyber Attacks

Kaspersky has recently concluded an investigation into cyber-attacks targeting the industrial sector in Eastern Europe. The investigation has revealed the employment of advanced tactics, techniques, and procedures (TTPs) by threat actors to compromise industrial organizations in the region. Industries such as manufacturing, industrial control system (ICS) engineering and integration have been particularly affected, emphasizing the urgent need for enhanced cybersecurity preparedness.

According to the research a series of targeted attacks was revealed, aiming at data -breach through the creation of a channel with similarities to cases previously reported, such as ExCone, and DexCone, a fact that clearly manifests the participation of APT31 (also known as Judgement Panda and Zirconium).
