1. February Insights and Trends
Chapter 1 features an analysis of information collected through Logpresso CTI during February 2024. This data was collected based on IoC information derived from the results of a dynamic analysis of malware, domestic and overseas information collected through OSINT techniques, and Honey Pots (a system intentionally installed in order to detect abnormal access).
According to the data, February, despite having fewer days than regular months, exhibited a remarkably high level of malicious bot infection rates. This level was comparable to the special period of year-end holidays in November and December.
- Malicious IP Addresses
- Lookalike Domains
- Malicious Bot Infections
- Credential Leaks

Logpresso Cyber Threat Intelligence
Logpresso is a specialized company in security and IT operations(SecOps), established in 2013. We offer security operation solutions such as log management, SIEM(Security Information and Event Management), SOAR(Security Orchestration, Automation, and Response), and DFIR(Digital Forensic & Incident Response) based on our fundamental technology.
Logpresso CTI is a cyber threat intelligence service optimized to immediately utilize such security threat information in security information and event management (SIEM) / security orchestration, automation, and response (SOAR) platforms. Relying on various open-source intelligence (OSINT) data sources such as the dark web and deep web, Logpresso CTI provides intelligence feeds that can detect various cyber-attacks including advanced persistent threats (APT), phishing, and credential stuffing.
Unlike many CTI services that are only available on a limited basis through API, Logpresso CTI synchronizes all indicators of compromise (IoC) directly to SIEM/SOAR, enabling full, real-time investigation of all logs. Unlike existing security architectures that primarily rely on detection through security devices, our approach enables the detection of threats proactively before a direct attack occurs.
