Phishing Campaigns Leveraging Pre-Filled Login Pages and Telegram for Credential Theft
Researchers have identified sophisticated phishing campaigns targeting users of major web hosting and email services, employing advanced techniques to steal credentials and payment information. In one case, customers of Aruba S.p.A., a leading Italian web hosting provider, were targeted with phishing emails that mimicked official notifications about expiring services or failed payments. Victims were directed to fake login and payment pages, where their email addresses were pre-filled to enhance credibility. The phishing kit used in this campaign incorporated CAPTCHA filtering to evade detection and utilized Telegram bots for real-time exfiltration of stolen credentials and credit card details.
A parallel campaign has been observed where users receive fake spam filter alerts, claiming that important emails have been blocked due to a supposed system upgrade. These emails, appearing to originate from the recipient's own domain, prompt users to log in via a link to a spoofed webmail page, again with pre-filled email addresses. The phishing sites employ tactics such as repeated invalid login prompts to harvest passwords and use obfuscated code and websockets for instant credential theft. In both campaigns, Telegram is used as the primary channel for attackers to receive stolen data, highlighting a trend in the use of messaging platforms for cybercriminal coordination and data exfiltration.
