Steve works as an analyst in a UK-based firm.

The scenario described by Steve's observations, where multiple logins are occurring from different locations in a short time span, especially from locations where the organization has no business relations, points to 'Geographical anomalies' as a key indicator of compromise (IoC). Geographical anomalies in logins suggest unauthorized access attempts potentially made by attackers using compromised credentials. This is particularly suspicious when the locations of these logins do not align with the normal geographical footprint of the organization's operations or employee locations. Monitoring for such anomalies can help in the early detection of unauthorized access and potential data breaches.
