Bot

What is Mirai Bot? Mirai is a malware that turns networked devices running Linux into remotely controlled “bots” that can be used as part of a botnet. This network of bots is often used to conduct massive Distributed Denial of Service (DDoS) attacks. Key Points about Mirai: Discovery: Mirai was first detected in September 2016 after it was used to launch a record-breaking DDoS attack exceeding 620 Gbps against security blogger Brian Krebs’ website, KrebsOnSecurity.com. Targets: Mirai primarily targets Internet of Things (IoT) devices such as security cameras, webcams, and routers that run on Linux and have weak or default login credentials. Infection Method: The malware continuously scans the internet for vulnerable devices. Once found, it attempts to log in using a list of 62 common default usernames and passwords. The alarming number of insecure IoT devices allows Mirai to compromise hundreds of thousands of devices. Impact: Mirai botnets have been used to launch some of the largest and most disruptive DDoS attacks in history, causing significant outages and disruptions to online services. CISA Alert on Mirai: The Cybersecurity and Infrastructure Security Agency (CISA) in the US issued an alert (TA16-288A) about the Mirai botnet, highlighting the threat it poses to internet infrastructure and urging users and organizations to take steps to mitigate the risk. ...
