Threat researchers at Cyble first discovered the cache of stolen cards. Threatpost reported this week that “Threat actors have leaked 1 million stolen credit cards for free online as a way to promote a fairly new and increasingly popular cybercriminal site dedicated to…selling payment-card credentials.” In an effort to build traffic on the dark web to AllWorld.Cards, hackers have posted millions of credit card numbers purportedly for free to anyone who wants to download them. Now, millions of stolen credit card numbers have appeared on the dark web for free. Many data breaches have occurred over the past few years, and as a result, there is a treasure trove of stolen personal information out there belonging to innocent victims.
