Half of the highest 20 most dear public U.S. firms had a minimum of 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 methods 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 provides recommendation on how you can defend your individual group from this risk.
By permitting the identical credentials to entry disparate methods, SSO provides 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 dedicate to essential duties. And fewer credentials means fewer password resets and different points in your assist desk and IT employees.
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 a wide range of functions and methods. Analyzing the Darkish Internet, BitSight discovered that 25% of the businesses on the S&P 500 and half of the highest 20 most dear public U.S. firms had a minimum of one SSO credential on the market in 2022.
Since January of 2022, there’s been a gradual progress within the variety of SSO credentials from public firms on the market on the Darkish Internet, in accordance with BitSight. In June and July, greater than 1,500 new credentials turned out there on the market. Although every kind of firms are susceptible, most impacted have been these within the expertise, manufacturing, retail, finance, vitality and enterprise companies 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 reduce off its relationship with the seller. In one other incident, a massive phishing assault compromised nearly 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 could be comparatively trivial to steal from organizations, and lots of organizations are unaware of the essential threats that may come up particularly from stolen SSO credentials,” mentioned BitSight co-founder and CTO Stephen Boyer. “These findings ought to increase consciousness and encourage immediate motion to turn out to be 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 provides 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 in case you’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 pointers to determine whether or not to grant the login request. For instance, this technique seems at such elements as location, day and time, consecutive login failures and supply IP tackle to assist decide if the request is coming from the precise person.
Think about 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 secret is required for authentication, any fraudulent makes an attempt to steal the credentials will fail. A latest 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 mentioned. “As we’ve seen repeatedly, insecure vendor credentials can present malicious actors with the entry they should goal massive buyer bases at scale. The impression of a single uncovered SSO credential may very well be far reaching.”
