Surge in APTs and Medusa Ransomware Threats

Advanced persistent threats (APTs) have surged, affecting 25% of companies and making up 43% of high-severity cybersecurity incidents, according to Kaspersky. These sophisticated, human-driven attacks exploit vulnerabilities across various sectors, particularly in IT and government. The Medusa ransomware has targeted over 300 critical infrastructure organizations since 2021, using an affiliate model and double extortion tactics. The Cybersecurity and Infrastructure Security Agency and the FBI have issued advisories to mitigate such threats, emphasizing updated software and network traffic filtering. Ransomware attacks in Europe have increased, with AI enhancing phishing and social engineering tactics, requiring improved cybersecurity measures. The integration of AI in both offensive and defensive strategies marks a significant evolution in the cybersecurity landscape.
