Trend Micro is a company famous for its anti-virus software, yet not very famous for its invasive website crawling. It isn’t exactly something that the company would want to make public, considering how hypocritical the actions are.
Websites have files named robots.txt, which tells search engines and other bots areas that are off limits, but Trend Micro ignores these. Additionally, Trend Micro doesn’t identify itself as a bot, but rather tries to disguise itself as a user. Trend Micro behaves exactly the same way that hackers do, and that’s not cool.
Trend Micro operates on two IP ranges, based out of America and Japan. Block these ranges in your web server’s config file.
