On November 1st, 2022, Dropbox became the victim of a cyber attack where source code repositories, as well as names and emails of their employees, were unauthorizedly accessed.

It is not yet clear how the unauthorized access took place, but Dropbox has said that they are investigating the matter. The company is urging all users to change their passwords as a precautionary measure.

This breach comes a couple of years after another high-profile data leak at Dropbox. In that incident, a user’s account was hacked, and a file containing the email addresses and hashed passwords of over 68 million Dropbox users were leaked.

Dropbox has not yet released any information on how many users were affected by this latest breach. However, given the sensitive nature of the data that was accessed, it is possible that the number of affected individuals could be quite high.

Dropbox Breach Attack Details

On Tuesday, November 1st, 2022, San Francisco-based firm Dropbox disclosed that it had been the victim of a phishing campaign, which lead to the unauthorized access of 130 source code repositories on GitHub. Third-party libraries modified for use by Dropbox were the main victims, with core apps saved from the threat actor.

Along with the leaked source code repositories, the phishing attack also gained access to thousands of names and email addresses belonging to Dropbox employees. Sales leads and vendors’ information have also been breached.

According to Dropbox, the attack started in early October 2022 when employees received phishing emails from the attacker who posed as CircleCI. The emails slipped through spam detection filters and landed in employees’ inboxes.

The emails asked the receiver to click on a link to CircleCI’s login page, where they were asked to enter their GitHub username, password, and hardware authentication key.

Unbeknownst to the employees, the email was not legitimate. Their act of logging into the fake CircleCI login page and inputting their credentials allowed the attacker to enter Drop Box repositories and access sensitive information.

What We Can Learn From the Incident

When it comes to cyber security, there’s a lot we can learn from the Dropbox breach.

For one, it’s a reminder that no company is immune to attack. No matter how big or small, every business is at risk of being targeted by hackers.

Secondly, the Dropbox breach highlights the importance of having strong security measures in place. While Dropbox did have some in place, they were not enough to prevent the attack from happening.

Lastly, the incident reminds us that even the most well-protected companies can be vulnerable if their employees are not properly trained on how to keep their data safe. In the case of Dropbox,  employees fell for a phishing scam that allowed hackers to gain access to the company’s systems.

While the Dropbox breach is certainly a cause for concern, it also provides us with an opportunity to learn from our mistakes and strengthen our own cyber security defenses. By taking the necessary steps to protect our data, we can help prevent future incidents from occurring.

Plan of Action: Preventing a Cyber Security Breach in Your Company

The human factor is the most important layer of defense against phishing attacks. Even the most tech-savvy users can fall for a phishing attack if they’re not aware of the dangers. That’s why continuous awareness training is so important. It reminds us how to protect ourselves and our companies from these dangerous attacks.

So how do we prevent something like this from happening to our own company? Here are key points of action.

  1. Implement an awareness program that includes simulations of different types of phishing attacks. This can help your employees learn how to identify suspicious emails and report them to the security team.
  2. Another important step is to inform users of the authorized cloud services and their official web domains. This way, they can be on the lookout for emails that may be spoofing these domains.
  3. Finally, it is important to have a process in place that encourages and facilitates the reporting of suspicious email messages. This way, the security team can quickly triage and act on malicious messages.

When you receive an email, there are a few things you can do to make sure it is legitimate. First, check that the sender is someone you know and trust. Then, make sure that the domain and email address match up. For example, if you receive an email from your bank, the domain should be “@yourbank.com”.

If you’re not sure about the email, don’t click on any links inside it. Instead, hover over the link with your mouse to see the full URL. If it looks suspicious, don’t click on it.

Finally, pay attention to spelling. Sometimes threat actors will substitute letters to make the URL look real. For example, they might switch the letter “o” with the number zero. If you’re not sure about the email, it’s best to err on the side of caution and not click on any links inside it.

A Final Word

As we’ve seen from the recent Dropbox incident, there are many ways that cyber security breaches can occur. By taking some simple steps, however, you can help to prevent them from happening in your company.

Make sure that all of your employees are aware of the importance of cyber security, and that they know how to spot potential threats. Encourage them to report any suspicious activity to you or to the IT department.

Some additional precautionary measures:

  • Make sure that your passwords are strong and that you change them regularly. Consider using a password manager to help with this.
  • Make sure that your antivirus and anti-malware software is up to date, and that you run regular scans.
  • Keep your operating system and software up to date, as well. Security patches are often released in response to new threats, so it’s important to ensure that you have the latest versions.
  • Consider investing in a good cyber security solution for your business. There are many different options available, and the right one for you will depend on your specific needs.

By taking these steps, you can help to protect your company from cyber security breaches.
