Additionally, there were 93 events associated with infostealer activity, with Redline and LummaC2 being the most prevalent malware families. The timeline indicates a surge in client-related events from September 2025 through April 2026, with a notable increase in employee-related events in March and April 2026. The exposure primarily affects clients, with 288 instances, and employees, with 93 instances, over the period from July 2025 to June 2026. The risk score of 73 suggests a high level of exposure. The high volume of data breaches linked to combolists and the presence of infostealer malware indicate a strong risk of credential compromise and potential unauthorized access to sensitive information. The concentration of events targeting login and logon services on smi2.ru, coupled with the prevalence of Windows operating systems, suggests that attackers are actively attempting to exploit user credentials. Prioritization should focus on immediate credential hygiene, including widespread password resets and multi-factor authentication enforcement for both employees and clients, alongside enhanced monitoring for suspicious login activity and further investigation into the root cause of the data breaches.
