Half of the highest 20 most precious public U.S. firms had at the very least one single sign-on credential up on the market on the Darkish Internet in 2022, says BitSight.
Single sign-on, or SSO, is taken into account an efficient technique of authentication as a result of it reduces the necessity for passwords and lets customers authenticate throughout totally different functions and techniques with only one single set of credentials. However what occurs in case your SSO credentials are compromised by attackers and used in opposition to you? A report revealed Monday by cybersecurity reporting service BitSight discusses the theft of SSO credentials and affords recommendation on methods to defend your personal group from this menace.
By permitting the identical credentials to entry disparate techniques, SSO affords a number of advantages, with three particular ones outlined by BitSight. Fewer account credentials means fewer targets for phishing assaults. Much less time coping with login makes an attempt means extra time that your workers can commit to vital duties. And fewer credentials means fewer password resets and different points on your assist desk and IT workers.
How are cybercriminals accessing SSO credentials?
The draw back with SSO credentials is that they’re significantly desired by cybercriminals who can use them to achieve entry to quite a lot of functions and techniques. Analyzing the Darkish Internet, BitSight discovered that 25% of the businesses on the S&P 500 and half of the highest 20 most precious public U.S. firms had at the very least one SSO credential on the market in 2022.
Since January of 2022, there’s been a gentle development within the variety of SSO credentials from public firms on the market on the Darkish Internet, in line with BitSight. In June and July, greater than 1,500 new credentials turned obtainable on the market. Although all types of firms are weak, most impacted had been these within the know-how, manufacturing, retail, finance, vitality and enterprise providers sectors.

What can occur if SSO credentials are compromised?
In an assault in opposition to SSO vendor Okta in January of 2022, cybercriminals used the stolen credentials from one of many firm’s distributors to breach Okta itself. In the long run, Okta lower off its relationship with the seller. In one other incident, a big phishing assault compromised virtually 10,000 login credentials and greater than 5,000 multi-factor authentication codes from 136 totally different firms. Affected organizations included Twilio, Cloudflare and Okta.
“Credentials might be comparatively trivial to steal from organizations, and lots of organizations are unaware of the vital threats that may come up particularly from stolen SSO credentials,” stated BitSight co-founder and CTO Stephen Boyer. “These findings ought to increase consciousness and encourage immediate motion to develop into higher acquainted with these threats.”

How can organizations defend their SSO credentials?
To guard your group’s SSO credentials from compromise and Darkish Internet gross sales, BitSight affords the next three suggestions:
Don’t rely simply on conventional multi-factor authentication
Through the use of phishing campaigns, attackers can steal SSO credentials even if you happen to’ve enabled MFA. How? A cybercriminal targets your workers with a phony login web page. An unsuspecting recipient enters their credentials in addition to their MFA code, giving the attacker entry to the account and any licensed information and functions.
Flip to adaptive MFA
Adaptive MFA improves on conventional authentication by assigning contextual guidelines and tips to resolve whether or not to grant the login request. For instance, this technique seems at such components as location, day and time, consecutive login failures and supply IP tackle to assist decide if the request is coming from the precise consumer.
Take into account common two-factor authentication
Common two-factor authentication, or U2F, usually makes use of a bodily safety key or fob as a single sign-in technique. Since a bodily key’s required for authentication, any fraudulent makes an attempt to steal the credentials will fail. A current cyberattack in opposition to content material supply community Cloudflare was prevented because of the firm’s use of U2F keys.
“Companies want to concentrate on the dangers posed by their main IT distributors,” Boyer stated. “As we’ve seen repeatedly, insecure vendor credentials can present malicious actors with the entry they should goal massive buyer bases at scale. The affect of a single uncovered SSO credential might be far reaching.”
