Unexpected cyber hygiene principles to know to enhance personal and corporate security
Since the beginning of the Russian invasion in 2022, cyberspace has become an arena of intense attacks affecting both corporate and personal security.
On January 13-14, 2022, a massive attack on Ukrainian government websites was carried out with reports of an alleged personal data leak. Soon after, the WhisperGate malware was discovered, which was aimed at destroying files at government, non-profit, and tech organisations. On January 19, a group of hackers called Gamaredon attempted to compromise a government agency in Ukraine for the purpose of cyber espionage. Since March 6, attacks against civilians have increased, especially phishing and malware for personal devices.
February 2022 saw a series of Ghostwriter phishing attacks targeting Ukrainian government agencies to steal confidential information. At the same time, the HermeticWiper malware attack targeted government information resources, destroying important data.
“In the face of modern cyber threats, it is important to integrate a comprehensive approach to cyber hygiene.”
March 2022 brought the DDoS attack “Operation: Isolation” DDoS attack on Ukrainian banking institutions, causing network overload and denial of service. In April 2022, there was an attack on the supply chain through the compromise of software used by Ukrainian manufacturers and distributors of energy equipment. Social engineering techniques, including fake calls and messages, were used to manipulate employees and gain unauthorised access to systems.
These incidents highlight the need for knowledge of cyber threats to corporate security and personal data protection. These developments reinforce the need for a comprehensive approach to cybersecurity, including updating security systems, educational programmes to raise employee awareness, and developing strategies to effectively respond to cyber incidents. In the context of military conflict, cybersecurity becomes a key component of national security, requiring coordinated efforts from the government, the private sector and individual citizens. Appropriate response to cyber threats, proactive identification of vulnerabilities and development of effective defence strategies are crucial to ensure resilience and security in the digital space in the face of growing uncertainty and changes in the global cyber landscape.
In the context of strengthening corporate and personal cybersecurity, especially in the face of modern cyber threats, it is important to integrate a comprehensive approach to cyber hygiene. According to current research in this area, the following key areas can be identified:
In summary, the modern cyber landscape, especially in the context of military conflicts, poses serious challenges to corporate and personal security. The evolution of cyber attacks, including phishing, malware, DDoS attacks and social engineering techniques, requires organisations and individuals to have a deeper understanding and a more progressive approach to cyber hygiene. Integration of solutions such as DNS query encryption, network isolation, advanced access control, use of honeypots, Zero Trust architecture, patch management automation, SIEM, least privilege principles, IAM, and Threat Intelligence are key to building an effective defence. An appropriate approach to cybersecurity is becoming an integral part of ensuring resilience and security at both the corporate and personal levels.
