- Threat IntelligenceI collect and analyze information about threats against Sicoob. This way, I help Sicoob to understand the panorama of threats and better prepare against cyber attacks and fraud. I always seek to identify threat trends against Brazilian financial institutions, taking into account attacks aimed at customers. Furthermore, I develop and manipulate tools that support me in proactively identifying threats. I developed tools that search for leaked/violated credentials of employees, customers and sensitive information from the institution itself, using as a source datasets/Dataleaks available on forums, Telegram groups, public gits, etc. Additionally, I developed some tools that search for phishing sites against customers and employees.- Threat HuntingI regularly search the organization's security mechanisms, mainly the SIEM, in order to analyze the logs and try to identify possible threats. If something suspicious is identified, carry out a detailed analysis.- Digital forensicsWhenever necessary, support in the execution of the process implemented in the institution, using the tools for collecting, examining, analyzing and recording the results obtained.- Malware AnalysisImplemented sandboxes to perform basic and advanced malware analysis. Basic analyzes are carried out using an automated tool (cuckoo). In cases that require a deeper analysis of malware, mainly involving banking malware, it is carried out in sandbox with static and dynamic analysis tools, so that a thorough analysis of the functions of the malware can be carried out, to identify how to protect our employees and customers.- Security Incident ResponseMost incidents are handled by Junior and Full Analysts, when they encounter difficulties in resolving incidents, they request the support of Senior Analysts. Whenever necessary, I support them in clarifying the problem and help them understand the response we gave to the incident.
