10K Microsoft Email Users Hit in FedEx Phishing Attack

[silversurfer]

Researchers are warning of recent phishing attacks targeting at least 10,000 Microsoft email users, pretending to be from popular mail couriers – including FedEx and DHL Express.
 
Both scams have targeted Microsoft email users and aim to swipe their work email account credentials. They also used phishing pages hosted on legitimate domains, including those from Quip and Google Firebase – allowing the emails to slip by security filters built to block known bad links.
 
“The email titles, sender names and content did enough to mask their true intention and make victims think the emails were really from FedEx and DHL Express respectively,” said researchers with Armorblox on Tuesday. “Emails informing us of FedEx scanned documents or missed DHL deliveries are not out of the ordinary; most users will tend to take quick action on these emails instead of studying them in detail for any inconsistencies.”
 
The phishing email spoofing American multinational delivery services company FedEx was entitled, “You have a new FedEx sent to you,” with a date that the email was sent.
 
This email contained some information about the document to make it seem legitimate – such as its ID, number of pages and type of document – along with a link to view the supposed document. If the recipients clicked on the email, they would be taken to a file hosted on Quip. Quip, which comes in a free version, is tool for Salesforce that offers documents, spreadsheets, slides, and chat services.

“We have observed a continuing trend of malicious actors hosting phishing pages on legitimate services like Google Sites, Box and Quip (in this case),” said researchers. “Most of these services have free versions and are easy to use, which make them beneficial for millions of people around the world, but unfortunately also lower the bar for cybercriminals to launch successful phishing attacks.”
