Vulnerable IoT devices are powerful platforms for building botnets that cause billion-dollar
losses every year. In this work, we study Bashlite botnets and their successors, Mirai botnets. …

IoT botnets have been used to launch Distributed Denial-of-Service (DDoS) attacks affecting
the Internet infrastructure. To protect the Internet from such threats and improve security …

Spam messages propagate malware, disseminate phishing exploits, and advertise illegal
products. Those messages generate costs for users and network operators, but it's difficult to …

One of the main problems in creating effective mechanisms to mitigate the spam problem is
the lack of more precise data on it. This paper describes the design and implementation of a …

This paper presents a methodology for the characterization of spamming strategies based on
the identification of spam campaigns. To deeply understand how spammers abuse network …

Current studies on spam evolution usually extract evolution patterns and trends by analyzing
historical spam message corpora. In this paper, we propose a novel methodology that …

IoT devices are often a vector for assembling massive botnets, as a consequence of being
broadly available, having limited security protections, and significant challenges in deploying …

A honeynet is a research tool consisting of a network specifically designed for the purpose of
being compromised, with control mechanisms that prevent this network from being used as …

We present here the work developed by NBSO/Brazilian CERT, in the “Brazilian Honeypots
Alliance–Distributed Honeypots Project”, to centralize the data gathered in several …
