An email phishing campaign is targeting popular YouTube creators with phony collaboration offers, according to researchers at CloudSEK. The emails contain OneDrive links designed to trick users into installing malware.
“The malware is hidden within attachments such as Word documents, PDFs, or Excel files, often masquerading as promotional materials, contracts, or business proposals,” the researchers explain.
“The phishing emails are sent from spoofed or compromised email addresses, making them seem credible. Recipients are lured into downloading the attached files, believing they are legitimate business offers....Once the attachment is opened, the malware installs itself on the victim's system. This malware is typically designed to steal sensitive data, including login credentials, financial information, and intellectual property, or to provide remote access to the attacker.”
The threat actors impersonate well-known brands and offer generous compensation in exchange for a 15-second ad spot. The emails are convincingly written in a professional tone.
CloudSEK was able to access the threat actor’s backend infrastructure, and found that they used automation to launch targeted phishing attacks against a large number of YouTube accounts.
“We also discovered a stealer log from the threat actor’s email account, exposing details of the entire campaign,” the researchers write. “This included SMTP email accounts (such as onet.eu and Murena.io), SOCKS5 proxies, Google Cloud APIs, victim emails and cookies, as well as phishing templates.
It appears that a multi-parser tool was used to collect data from YouTube, allowing the threat actor to obtain a large number of email addresses associated with YouTube channels as part of their initial reconnaissance efforts.”
