Dark Web activities: 10 signs that you’ve been breached (free PDF)

Many organizations are monitoring the Dark Web for lost or stolen data as a means of detecting breaches and protecting against cyberattacks. This list looks at 10 activities that could signal that your data has been compromised.

From the list:

1. Doxing of a company VIP
Dark Web and clear web sites like Pastebin are a dumping ground for personal, financial, and technical information with malicious intent. There is often a motivation behind these posts, such as political beliefs, hacktivism, vigilantism, or vandalism. For example, the executive of a wealth management firm was included in a large-scale dox as the result of their political contributions.

2. Full PANs, BINs, and payment cards for sale
The economy for payment cards on the Dark Web is strong, with a single card costing between $5 and $20. Sellers update markets with new cards regularly—sometimes even daily, the report said. And business and platinum cards will net criminals a higher price than average cards.

3. Guides for opening fraudulent accounts
On the Dark Web, you can find guides for sale that contain detailed, step-by-step instructions on how to exploit or defraud an organization. The guides serve two purposes: Criminals learn how to break into a company’s systems and processes, and the company’s brand name is promoted to criminals as a result of the listing. For instance, when a major US bank changed security policies, criminals updated guides with techniques to get around those changes.

4. Proprietary source code
A leak of source code can allow competing companies to steal intellectual property. It can also allow hackers to review the code for potential vulnerabilities to be exploited. Leaks of source code from tech giants will make the news, but source code from others is regularly leaked on sites like Github and Pastebin, as developers seek advice and input from others.
