Quote:Hackers are using search-engine optimization (SEO) tactics to lure business users to more than 100,000 malicious Google sites that seem legitimate, but instead install a remote access trojan (RAT), used to gain a foothold on a network and later infect systems with ransomware, credential-stealers, banking trojans and other malware.
eSentire’s Threat Response Unit (TRU) discovered legions of unique, malicious web pages that contain popular business terms/particular keywords, including business-form related keywords like template, invoice, receipt, questionnaire and resume, researchers observed, in a report published Wednesday.
Attackers use Google search redirection and drive-by-download tactics to direct unsuspecting victims to the RAT—tracked by eSentire as SolarMarker (a.k.a. Jupyter, Yellow Cockatoo and Polazert). Typically a person who visits the infected site simply executes a binary disguised as a PDF by clicking on a purported “form” — thus infecting his or her machine.
“This is an increasingly common trend with malware delivery, which speaks to the improved security of applications such as browsers that handle vulnerable code,” researchers wrote. “Unfortunately, it reveals a glaring blind spot in controls, which allows users to execute untrusted binaries or script files at will.”
