Description

Cybersecurity firm Netcraft has issued a warning regarding a new phishing campaign exploiting compromised email accounts. Threat actors are utilizing compromised email accounts to send phishing emails containing links to PDF files hosted on Autodesk Drive. In these incidents, attackers are using compromised email accounts to send phishing emails to contacts, leveraging the sender's signature footers to make the messages appear legitimate. The phishing emails contain shortened links to malicious PDFs hosted on Autodesk Drive, along with the sender's name and company name to enhance credibility. When recipients attempt to view the document, they are directed to a phishing page requesting their Microsoft account username and password. After providing their login information, victims are redirected to a seemingly innocuous OneDrive-hosted document related to real estate investment, concealing the fact that their credentials have just been stolen. Netcraft warns that with victims' Microsoft credentials, the attackers could gain unauthorized access to sensitive company data and perpetrate further phishing attacks using the compromised accounts. Autodesk Drive, a data sharing platform, is being exploited by attackers to host malicious PDF documents. According to Netcraft, these attacks have been tailored for various countries and regions, as evidenced by the existence of malicious PDF documents in multiple languages on Autodesk Drive. The scale of these attacks, coupled with the use of customized PDF documents, suggests a level of templating and automation. Netcraft cautions that this well-targeted campaign has the potential to spread worldwide rapidly.
