Why we think so

Rambler.ru is a major Russian web portal and email service with high traffic, registering around 88 million monthly visits, mostly from Russia. The domain ranks #485 globally and offers a wide range of news and media content. It uses standard and paid analytics and advertising technologies, including Google Analytics, Yandex Metrics, and Amazon services. The domain is secured with a valid SSL certificate from GlobalSign. Public contact info includes multiple emails linked to Rambler and active social media accounts on Facebook, Twitter, and Instagram. Trademark records confirm longstanding use of the "RAMBLER" mark since early 1900s. However, Rambler.ru suffered a significant data breach around 2012 that exposed nearly 100 million user accounts with plaintext passwords. Consequently, @rambler.ru emails are frequently found in spam and hacking cases. User reviews reflect issues like poor customer support, account access problems, and account hijacking incidents. Rambler itself is a real and established service, but caution is advised when dealing with emails or accounts from this domain due to past security incidents and widespread abuse.
