ESET has reported that the Gamaredon group, a known cyber threat actor, has ramped up its activities with 35 distinct spear-phishing campaigns targeting Ukrainian governmental and military institutions in 2025, particularly in the latter half of the year. These campaigns are part of ongoing efforts to exploit vulnerabilities in these sectors amid the ongoing conflict in Ukraine. The attacks primarily use deceptive emails to trick recipients into revealing sensitive information or downloading malicious software. This increase in activity poses significant risks to national security and the integrity of critical infrastructure in Ukraine, highlighting the persistent threat posed by cyber warfare in the region. As these attacks continue, it is crucial for organizations to enhance their cybersecurity measures and remain vigilant against phishing attempts.

A recent phishing campaign is targeting hotels in Europe and Asia by using deceptive emails that reference common operational issues, such as guest complaints and health inspections. The attackers employ a Node.js implant to execute their malicious activities. Microsoft has not linked this campaign to any known threat actor, making it difficult to predict future attacks. The phishing email lures are designed to exploit hotel staff's urgency to resolve these issues, potentially leading to compromised systems and data breaches. This incident serves as a reminder for hospitality businesses to remain vigilant against phishing attempts that exploit everyday concerns.
