How to Prevent Corporate Login Credential Theft?

Breaches caused by stolen or compromised credentials had an average cost of $4.5m in 2021, and take longer to identify and contain (327 days).

 

Expenditure on enterprise cybersecurity is growing rapidly. According to the most recent estimates, the average figure for 2021 will be more than $5 million. Despite this, US organizations reported a record number of data breaches in the same year. 

So, what's the problem? Static passwords, user errors, and phishing attacks continue to undermine security efforts. Threat actors benefit greatly from easy access to credentials. And user training alone will not be enough to restore the balance. A strong credential management strategy is also required, with multiple layers of protection to ensure credentials do not fall into the wrong hands.

During the first half of this year, nearly half of all reported breaches involved stolen credentials. Once obtained, these credentials allow threat actors to disguise themselves as legitimate users in order to deploy malware or ransomware or move laterally through corporate networks. Extortion, data theft, intelligence gathering, and business email compromise (BEC) can all be carried out by attackers, with potentially huge financial and reputational consequences. Breaches caused by stolen or compromised credentials cost an average of $4.5 million in 2021, and they are more difficult to detect and contain (327 days).

It may come as no surprise that the cybercrime underground is rife with stolen credentials. In fact, 24 billion were in circulation in 2021, a 65% increase over 2020. Poor password management is one factor.  Since password reuse is common, these credential hauls can be fed into automated software to unlock additional accounts across the web, a technique known as credential stuffing. They are quickly put to use once they are in the hands of hackers. 

As per one study, cybercriminals gained access to almost a quarter (23%) of accounts immediately after the compromise, most likely through automated tools designed to quickly validate the credibility of the stolen credential.

Phishing is a particularly serious enterprise threat that is becoming more sophisticated. Unlike the error-ridden spam of yesteryear, some efforts appear so genuine that even a seasoned pro would have difficulty detecting them. Corporate logos and typefaces are accurately reproduced. Domains may use typosquatting to appear identical to legitimate domains at first glance.

They may even use internationalized domain names (IDNs) to imitate legitimate domains by replacing Roman alphabet letters with lookalikes from non-Latin alphabets. This enables fraudsters to register phishing domains that look exactly like the original.

The same holds true for the phishing pages that cybercriminals direct employees to. These pages are intended to be convincing. URLs will frequently use the same tactics mentioned above, such as letter substitution. They also intend to imitate logos and fonts. These techniques make pages appear to be the "real deal." To trick users, some login pages display fake URL bars that display the real website address. This is why you can't expect employees to know which sites are legitimate and which are attempting to dupe them.

This means that user awareness programs must be updated on a regular basis to account for specific hybrid-working risks as well as constantly changing phishing tactics. Short, bite-sized lessons with real-world simulation exercises are required. Creating a culture in which reporting attempted scams is encouraged is also important.

But be aware that there is no silver bullet, and user education alone will not reliably prevent credential theft. Bad actors only need to be fortunate once. And there are numerous ways for them to contact their victims, including email, social media, and messaging apps. It is unrealistic to expect every user to detect and report these attempts. Education must use technology and solid processes.

Credential management should be approached in layers by organizations. The goal is to reduce the number of sites where users must enter passwords. Single sign-on (SSO) should be implemented by organizations for all reputable necessary work applications and websites. SSO should be supported by all SaaS providers.

In the meantime, a password manager would be useful if there are logins that require different credentials. This also allows employees to determine whether a login page can be trusted, as the password manager will not provide credentials for a site it does not recognize. To secure logins, organizations should also enable multi-factor authentication (MFA).

FIDO2 is also gaining popularity. It will provide a more robust solution than traditional authenticator apps, though those apps will still be superior to text-message codes. Not everything is foolproof, and risky login pages may slip through the cracks. Employees should only be flagged for risky login pages as a last resort. 

This can be accomplished by analyzing threat intelligence metrics, webpage similarities, domain age, and how users arrived at a log in page in real-time. This rating can then be used to either block high-risk login pages or warn users to check again for less-risky ones. Importantly, because this technology only intervenes at the last second, security appears transparent to the user and does not make them feel watched.

A layered approach to credential management, when combined with an architectural approach to security across the entire stack, can help reduce the attack surface and mitigate risk from an entire class of threat.
