'If they all came from a country where i don't even do business, that would be easy to defend. 'If they were coming from the same computer, it would be very obvious to defend against,' said Sumit Agarwal, Shape Security's co-founder and vice president of strategy. To bypass systems that look for multiple attacks from a single IP address, attackers use botnets to make it seem like the login attempts are all coming from different, and normally law-abiding computers. 'The idea behind all of them is to try to identify patterns in IP address, and the problem is that attackers are now using botnets to bypass those defenses.'Īccording to Shape Security, an average of 1 to 2 percent of stolen credentials from one site will work on a second site, meaning that a list of a million credentials will result in 10,000 hijacked accounts. 'You have all of these technologies that companies have deployed to try to protect against different forms of attack,' said Shuman Ghosemajumder, vice president of product management at Shape Security. Since the attack go after a different user name with each new attempt, no one account sees a suspicious number of failed logins. Plus, defending organizations have learned to stop these kinds of attacks by blocking multiple attempts to log into the same account, or multiple login attempts from the same IP address.Ī credential stuffing attack increases the attackers success rate and reduces the time it takes to break into accounts by using stolen lists of working login IDs and passwords from other sites, since many people use the same email addresses and passwords as their credentials in multiple locations. It's a difficult, time-consuming process. The traditional 'brute force' method of breaking into a user account requires the attacker to try numerous combinations of login ID and password.
