Financial information, bank account logins, IP addresses, domain names and other financial records are considered valuable details that can be used for many types of attacks.

Now, more of that data is being offered in unsavory places.

There was a 135 percent increase in bank data found on the dark web between the first six months of 2017 and the first six months of this year, according to a recent report from New York City-based firm IntSights.

“While it comes as no surprise that cybercriminals continue to target banking and financial services organizations, it’s important that CISOs (chief information security officers), threat hunters and SOC (security operation center) teams at these organizations are familiar with how they are being targeted,” Itay Kozuch, director of threat research at IntSights, said in a statement. “We see many financial organizations too focused on stopping direct attacks to their corporate systems; however, our research shows that cybercriminals have begun circumventing these defenses using social media, mobile application stores and phishing schemes.”

IntSights collects data on attack indications, leaked credentials, leaked credit cards and the creation of fake social network profiles, among other threat types as well. For this report, the company analyzed data collected on the top 50 banks and financial services organizations in the U.S. and Europe.

From the start of 2017 through the first half of 2018, cybercrime groups have generated billions of dollars worth of profit and have caused gross losses of more than $1 trillion to the markets because of their attacks, according to the World Economic Forum.

IntSights reported a 151 percent year-over-year increase in attack indications including include dark web chatter mentioning the company, the appearance of company assets (IP Ranges, domains, emails, and employee data) in target lists or campaigns and malware or malware code targeting these companies.

The company also reported a 91 percent increase in corporate email addresses found on phishing target lists, a 40 percent increase in corporate credential leakage, a 149 percent increase in stolen credit card data and a nearly 50 percent increase in fake social media accounts.
