Talent Lab and Indicators of Compromise

The data obtained by Honeypot sensors requires manual analysis and interpretation, and in most cases cannot be used in automated tools to identify the threat in other segments of the network. It is necessary to create and demonstrate a set of data that can be used as indicators of compromise (IoC) and which is received in an automated mode.

Thank you #ISCR2018 for the opportunity to share an expertise with the high-motivated audience. Probably, it will change something in their way of thinking. Anyway, the gift from Tokyo Cybercrimes Control Division gives me hope.

Next week at Seoul I will present at "International Symposium on Cybercrime Response" the following topic: “Tracking Cybercrime in IoThreat Era”. Within the presentation I will focus on IoT-related issues on perimeter, how to identify them and how to mislead the attacker.

New vulnerabilities in D-Link DIR-620 (RevG).
#CVE201812677 exposes all user credentials in config-file (plaintext) inside the firmware. It wouldn’t be so critical if part of the file was not stored in JS-variable, that available for unauthenticated user (#CVE201812419).

Tiesto, Aphrodite, SubFocus and... Denis. Still about #cybersecurity in Technology track. In case of emergency will sing something. #alfafuturepeople #AFP2018
