Fewer account credentials imply fewer targets for phishing assaults. Much less time coping with login makes an attempt means extra time your workers can spend on important duties. And fewer credentials means fewer password resets and different hassles to your assist desk and IT workers.
How do cybercriminals entry SSO credentials?
The draw back of SSO credentials is that they’re extremely desired by cybercriminals and can be utilized to achieve entry to quite a lot of purposes and techniques. Analyzing the Darkish Net, BitSight discovered that 25% of S&P 500 corporations and half of the 20 most precious US public corporations had a minimum of one SSO credential on the market in 2022.
Since January 2022, there was a gradual development within the variety of public firm SSO credentials on the market on the Darkish Net, in accordance with BitSight.

What can occur if SSO credentials are compromised?
In an assault towards SSO supplier Okta in January 2022, cybercriminals used stolen credentials from one of many firm’s suppliers to breach Okta. In the long run, Okta severed his relationship with the provider. In one other incident, a significant phishing assault compromised almost 10,000 login credentials and greater than 5,000 multi-factor authentication codes from 136 totally different corporations. Affected organizations included Twilio, Cloudflare, and Okta.
“Credentials could be comparatively trivial to steal from organizations, and plenty of organizations are unaware of the important threats that may come up particularly from stolen SSO credentials,” stated Stephen Boyer, co-founder and CTO of BitSight. “These findings ought to elevate consciousness and inspire quick motion to develop into extra acquainted with these threats.”

How can organizations shield their SSO credentials?
To guard your group’s SSO credentials from Darkish Net compromise and gross sales, BitSight affords the next three ideas:
Do not simply depend on conventional multi-factor authentication
By utilizing phishing campaigns, attackers can steal your SSO credentials even when you’ve got enabled MFA. How? A cyber felony assaults your workers with a faux login web page. An unsuspecting recipient enters their credentials in addition to their MFA code, giving the attacker entry to the account and all licensed knowledge and purposes.
Change to adaptive MFA
Adaptive MFA improves on conventional authentication by assigning contextual guidelines and pointers to resolve whether or not to grant the login request. For instance, this technique seems to be at elements corresponding to location, day and time, consecutive login failures, and supply IP handle to assist decide if the request is from the actual consumer.
Take into account Common Two-Issue Authentication
Common Two-Issue Authentication, or U2F, usually makes use of a bodily safety key or keychain as the only sign-on technique. Since a bodily secret’s required for authentication, any fraudulent try to steal credentials will fail. A current cyberattack towards the Cloudflare content material supply community was prevented by the corporate’s use of U2F keys.
“Enterprises want to pay attention to the dangers posed by their main IT distributors,” Boyer stated. “As we now have seen repeatedly, insecure vendor credentials can present malicious actors with the entry they should goal giant buyer bases at scale. The affect of a single uncovered SSO credential may very well be far-reaching.”
