Phishing Campaigns Use Real-Time Checks to Validate Victim Emails Before Credential Theft

Summary: Researchers are highlighting a new credential phishing tactic called precision-validating phishing, which uses real-time email validation to target select high-value individuals. This method aims to enhance the success rate of data theft by validating emails before showing phishing pages, thereby increasing the quality of stolen credentials. Additionally, a separate phishing campaign utilizes file deletion alerts as bait, leading users to bogus login screens or malware downloads.
