Impossible travel is a cybersecurity detection method used to identify potential compromise or unauthorized access to user accounts. It detects instances where a user's account is accessed from two different countries within an unreasonably short timeframe, suggesting that conventional travel between those locations would be impossible.
Impossible travel works by analyzing user login activities and correlating them with geographical locations. It takes into account factors such as the user's IP address, user agent, and other session attributes. By comparing the timing and location of different login events, impossible travel detection algorithms can determine if the travel between the detected locations is implausible or impossible within the given timeframe.
To detect impossible travel incidents, a comprehensive mechanism is implemented that analyzes and records user behavior. This mechanism consumes, enriches, and aggregates billions of activities per day through a stream processing job. User visits to different countries are stored as aggregated visit activities, including user agents, IP addresses, and other relevant information. When a new event occurs, it is correlated with the stored visits to identify potential impossible travel incidents. By comparing aggregated properties of visits, unnecessary alerts can be avoided. For example, if the user agents utilized during two visits are similar, it suggests a legitimate scenario.
The detection process involves the following steps:
IRONSCALES is a comprehensive cybersecurity solution that combines multiple advanced technique, to provide robust protection against Business Email Compromise (BEC) and impersonation attacks. By leveraging the capabilities listed below, IRONSCALES helps organizations proactively identify and prevent these sophisticated threats.
Impossible Travel Detection: IRONSCALES employs impossible travel detection to identify potential compromises in user accounts. By analyzing login activities and correlating them with geographical locations, the platform can detect instances where a user's account is accessed from two different countries within an unreasonably short timeframe. This helps uncover unauthorized access or compromised user accounts, which are often associated with impersonation attempts.
Sender Analysis: Sender analysis is a critical component of IRONSCALES' defense against BEC and impersonation. The platform utilizes advanced algorithms to analyze sender attributes, including email addresses, domain reputation, and email authentication mechanisms like SPF, DKIM, and DMARC. By comparing sender information with known trusted sources, IRONSCALES can accurately identify potential impersonation attempts and block malicious emails from reaching recipients.
Anomaly Detection: IRONSCALES incorporates anomaly detection techniques to identify deviations from normal patterns and behaviors. By establishing baselines of normal user behavior and communication patterns, the platform can detect anomalies such as sudden changes in financial requests, unusual communication patterns, or atypical sender behavior, which are common signs of BEC attacks. Anomalies trigger alerts for further investigation and potential blocking of malicious emails.
Behavior Analysis: Behavior analysis is a key feature of IRONSCALES' defense mechanism. The platform continuously monitors user behavior, communication patterns, and interactions to establish individual profiles. By analyzing deviations from established behavioral baselines, such as unusual login locations, abnormal email sending patterns, or suspicious attachment behavior, IRONSCALES can identify potential impersonation attempts and flag them for closer scrutiny.
Crowdsourced Threat Intelligence: IRONSCALES leverages crowdsourced threat intelligence, which involves aggregating data across it's 20,000+ SOC analysts using the platform to identify emerging threats and patterns. By utilizing a vast network of threat intelligence feeds, the platform can stay up-to-date with the latest zero-hour attacks.
IRONSCALES empowers businesses to stay one step ahead of cybercriminals, mitigating the risks associated with these increasingly sophisticated threats.
