From January 2018 through June 2019, Akamai recorded more than 61 billion credential stuffing attempts and more than 4 billion web application attacks. Today, we're releasing a special edition of the State of the Internet/ Security report that focuses on data within the high tech, video media, and entertainment sectors -- collectively named Media & Technology.
I have been playing close attention to Internet of Things (IoT) malware targeting systems with Telnet enabled, while also collecting samples targeting systems with SSH enabled on port 22. I've collected over 650 samples landing in my honeypot within the last week. The earliest sample showed up on July 24th at 20:06. The honeypot allows logins using known default login credentials for root.
