What is the issue?
Scammers are using compromised servers and bogus links to lure LinkedIn users in providing their online credentials and payment card details.
How does this scam work?
- Scammers send a message to the target via a LinkedIn account.
- The message prompts the recipient to open the shared document which is sent via Onedrive.
- The message includes a fake link that redirects the recipient to a compromised website.
- Upon clicking the bogus link, a redirection script is used on the hacked server to divert the request to a second compromised server.
- Finally, the URL redirects to a fake Microsoft Office 365 login phishing page, where the recipient is asked to enter the account credential.
More details about the scam
A Sophos employee received a similar scam message in his LinkedIn account. Upon suspicion, the Sophos team analyzed the embedded URL, which redirected to the website of a professional entertainer in the USA, whose server had been compromised.
“Hi, Hope all is well? I have shared a document with you via Onedrive, please see the shared document,” the message read.
The second server was a business site in Mexico. The team said that the affected site in Mexico has already spotted this scam and removed the offending content because it led to a 404 error page. All the other subdomains analyzed by the research team redirected to various dating site portals.
“Nevertheless, the redirection script provided the crooks with a general-purpose mechanism for running a range of different spamming, phishing and scamming campaigns at the same time, with the target site determined by the URL that the crooks used each time,” Sophos team noted.
