Threats Tagged 'bulk email abuse'

On May 15, 2026, Huntress agents detected an intrusion where threat actors compromised a terminal server to stage a massive phishing campaign rather than deploy ransomware. The attacker used legitimate bulk email software (Gammadyne Mailer) with a project file named 'dracii' (Romanian for 'the devils') and six recipient lists containing 8,894,920 email addresses. Operating from Romanian IP addresses, the actor impersonated UK pharmacy chain Boots through a fake customer satisfaction survey designed to harvest personal and payment card data. The phishing kit was hosted on a compromised Bolivian government website (ipelc.gob.bo), which Huntress reported to Bolivia's national CSIRT. The campaign used direct-to-MX delivery to bypass mail relays, with the mailer configured to send from 666 threads simultaneously. Evidence suggests this Romanian operator has been running multiple UK-targeting campaigns since at least July 2025, rotating between retail, tax, and cryptocurrency themes.
