"New Banking Trojan CHAVECLOAK Targets Brazilian Users via Phishing Tactics"
A new banking Trojan called "CHAVECLOAK" targets Brazilian users through phishing emails with PDF attachments. According to Cara Lin, a Fortinet FortiGuard Labs researcher, the attack involves the PDF downloading a ZIP file and then executing the final malware using DLL side-loading techniques. Contract-themed DocuSign lures are used to trick users into opening PDF files with a button to read and sign the documents. Clicking the button triggers the retrieval of an installer file from a shortened remote link.
