How Dropbox Hackers Carry Out Dropbox E-Mail Spam?

For users who use the file hosting service Dropbox, it is prudent to keep a vigilant eye on fake e-mail notifications. These notifications claim that you have new Dropbox messages. The fraudulent Dropbox e-mails are cleverly designed to steal your account information.

Upon clicking the links embedded in the Dropbox spam e-mails, users get redirected to a Dropbox login page. They have to enter their login credentials on this carefully replicated Dropbox homepage. Once the hackers gain access to the login credentials of the users, it opens up a sea of opportunities for them.

  • They can hijack the e-mail account and use it to conduct scam, spam and malware campaigns in the user’s name.
  • They can also use the stolen login credentials for gaining access to linked services such as app stores and online file storage.
  • They can view and download personal files which the victim has stored.
  • They can conduct fraudulent transactions in the name of the victim.
  • They can gather enough information about the victim to steal their identity altogether.

 

Hybrid Dropbox Malware Attacks

Hackers don’t always send phishing e-mails to Dropbox for gaining unauthorized access to Dropbox credentials. A closer look at Dropbox phishing e-mails reveals they are hybrid attacks to compromise other user credentials. Consider the following Dropbox phishing attempt.

A user received a Dropbox mail which offered a Dropbox invite to an Excel file. The landing link in the e-mail pretended to use an HTTPS connection. It achieved this by using sub-domains. Since most people consider HTTPS websites to be safe, the Excel icon in the e-mail launched the browser and took the victim to a fake website. The user landed on MyDropbox Login page, and hackers harvested the username and password twice. It then landed the user on the legitimate Microsoft site.

When investigators analyzed the link carefully, it turned out that it was an Office 365 fake e-mail. It was cleverly designed to compromise the Microsoft credentials of the victim, in addition to the Dropbox credentials.

 

How To Safeguard Yourself From Falling Prey To Dropbox Phishing Scams?

While recent years saw a rapid increase in users switching to cloud file-sharing platforms, there is a massive jump in Dropbox e-mail scams. Users can undertake the following steps to safeguard themselves from a Dropbox e-mail hack:

  • If the user receives an e-mail which seems like it’s from Dropbox saying, “Somebody wants to share a file”, login to Dropbox from the browser. It is a better choice than clicking on the link directly to view the shared data. Otherwise, the link will redirect the user to a fake Dropbox login page to obtain their credentials.
  • The hackers use sub-domains to spoof HTTPs. Lately, they are also registering for free SSL certificates. Hence, the time-tested precaution of trusting websites with an HTTPs tag is not useful anymore. Users must slow down and confirm the legitimacy of the source. If found illegitimate, it’s prudent to play it safe and avoid opening any attachments or clicking on any links.
  • It is prudent to use strong passwords, and users must choose a different password for every service. Using a two-step verification for Dropbox account helps users safeguard themselves from Dropbox e-mail scams. For users who use the Dropbox application on their mobile, it is advisable to set a passcode for the app.
  • If the users suspect receiving a Dropbox e-mail virus, they can report it by sending an e-mail to abuse@Dropbox.com. They can also report any phishing attempt which impersonates other Dropbox services. For browser blocking, users can also report malicious links to Internet Explorer or Safebrowsing.
