BeyondTrust Breach: A Wake-Up Call for Cybersecurity

Posted on by Srishti Chaubey

Introduction

Imagine this: An organization that promises to protect your passwords and block unauthorized access falls victim to the very attack it aims to prevent. That’s exactly what happened to BeyondTrust, one of the well-known companies in the privileged access management space, when attackers targeted their Remote Support SaaS instances earlier this month. The breach exposed a serious vulnerability CVE-2024-12356 that allows attackers to execute commands remotely. Though BeyondTrust responded with swift patching of the problem, the incident leaves several tough questions regarding the exploitations that can even take place against the best of defenses.

What Went Wrong in the BeyondTrust Breach?

On December 2, 2024, BeyondTrust noticed something unusual: attackers had seized an API key for their Remote Support SaaS. This gave them the power to reset application passwords and gain unauthorized access.

As they investigated, BeyondTrust uncovered two vulnerabilities:

  • CVE-2024-12356: A critical flaw that scored 9.8 out of 10 in severity and lets attackers inject commands remotely.
  • CVE-2024-12686: A medium-severity bug that allows attackers with admin privileges to upload malicious files.

What’s worse, CVE-2024-12356 wasn’t just a hypothetical risk. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) confirmed that attackers were already exploiting it in the wild.

The Irony

It’s hard to ignore the irony. BeyondTrust promised to protect against attacks like remote code execution and password theft, but attackers breached its defenses.

This isn’t the first time BeyondTrust has faced such a challenge. Last year, the company confirmed they were targeted after the Okta breach, underscoring how interconnected cybersecurity threats have become.

This is not BeyondTrust’s story alone but a stark reminder that no company, not even cybersecurity experts, is perfectly immune to attacks.

Why It Matters for Businesses

Thousands of organizations in healthcare, retail, and banking use BeyondTrust’s tools. A breach like this doesn’t just affect the company; it ripples out, impacting businesses that rely on their tools.

Here’s why this should matter to you:

  • Eroded Trust: Clients might start questioning the reliability of their systems.
  • Raising Risk: Exploited vulnerabilities can lead to data theft, operational issues, or worse.
  • Supply Chain Woes: If a key vendor is breached, one asks themselves how secure third-party software really is.

What You Can Do to Protect Your Business

Whether or not you use BeyondTrust’s products, it is a good time to take stock of your security practices. Here’s what you can do right now:

  1. Patch Your Systems: Update to the latest versions of BeyondTrust’s PRA and RS software.
  2. Check for Signs of Trouble: Review logs for unusual activity linked to API keys.
  3. Limit Your Exposure: Disable any unnecessary features and limit your access to the internet.
  4. Be Alerted: Monitor updates from BeyondTrust and cybersecurity agencies such as CISA.

Conclusion

The BeyondTrust breach is a reality check for everyone. Even the most trusted cybersecurity companies can get caught in the crossfire. It’s a reminder that no system is invincible and that vigilance is non-negotiable.

This means that organizations go beyond trust—pun intended—and actively work toward making their defenses stronger. They should update early, monitor their systems, and never assume they are safe. In today’s evolving world of cyber threats, one can only protect what matters most by staying a step ahead.

When Cache Keys Outlast Authentication Keys: A Glimpse into Okta’s Latest “Oops”

Posted on by Srishti Chaubey

In the security world, where precision is everything, Okta recently provided us with an example of how a single overlooked detail can shake up the user experience, especially if that “user” is a bad actor.

On October 30, 2024, Okta admitted to a vulnerability with a very unassuming title in its AD/LDAP Delegated Authentication (DelAuth) mechanism, which was fine until a username got a little too long. The key was a clever blend of Bcrypt-hashed elements: user ID, username, and password. However, if a username was 52 characters or longer, and the right cached key from a prior login was available, voilà—no password needed. Just enter the username, and you’re in.

Okta: 52 Character Username Fiasco

Security at Okta: It’s All About the Details… Or Is It?

As you might guess, these conditions weren’t common at all but still a little too close for comfort. To bypass the DelAuth system, the following criteria had to be met:

  • You were authenticating using Okta’s AD/LDAP DelAuth.
  • MFA was not turned on.
  • Your username was at least 52 characters long.
  • Authentication was cached by an earlier successful login and the network was unable to make it back to the actual AD/LDAP agent in real time.

This “free authentication” period ran from July 23 to October 30, 2024—a good three months where lucky 52-character usernames could breeze past password checks.

While most usernames aren’t likely to exceed 52 characters, and many systems don’t even allow usernames that long, the fact that Okta overlooking this detail in their hashing process is… noteworthy. After all, how many times are we going to expect security software companies to forget some basic boundary conditions?

Okta’s Recommendations, and the Reality

Okta quickly patched the vulnerability by switching from BCrypt to PBKDF2 for cache key generation. They asked affected customers to review system logs for suspicious logins from July 23 to October 30. That too under the assumption that customers knew about the 52-character username limit in the first place.

Okta’s advice is straightforward: enable MFA and use phishing-resistant authenticators—basic but effective security practices that still aren’t defaults. Okta emphasizes that these basics help mitigate risks, advising security-focused customers to double-check. Nothing quite says “proactive security” like asking your customers to pick up the slack caused by a missed code line.

Conclusion

A good piece of irony on top of a 52-character vulnerability from Okta is the use of passwords and BCrypt. BCrypt eats rainbow tables like cake but Its length limit problem is well known. Leaving cached keys in the middle with passwords so apparently involved in the process isn’t so much of that promised “passwordless,” is it? We also wonder the number of users and accounts that slipped through the gaps in Okta’s cache key handling.

In contrast, PureAuth offers a true passwordless experience. Our zero-trust model eliminates passwords, meaning no PII or customer data are on our server. We have no passwords, no caching issues, just genuine security. PureID’s proactive security isn’t just a promise; it’s our foundation, sparing you from tomorrow’s vulnerability headlines and ensuring robust defenses without compromise. #gopasswordless

Google 2FA Breach: Rethink Authentication Security

Posted on by Srishti Chaubey

In today’s digital landscape, safeguarding our online presence is paramount. Two-factor authentication (2FA) has emerged as a crucial tool in this endeavour. Platforms like Google and Facebook offer 2FA to bolster account security. However, there have been multiple incidents revealing vulnerabilities in this system, prompting concerns among users.

The Case of the Bypassed 2FA

Recent reports unveiled breaches in Gmail and YouTube accounts despite 2FA activation. This revelation underscores a fundamental truth: security with passwords, along with 2FA or MFA is fallible. Hackers continuously adapt their tactics, exploiting weaknesses even in trusted systems like 2FA.

Credit : Forbes

Understanding the Bypass

While the exact method remains undisclosed, hackers may employ various strategies to circumvent 2FA. According to Forbes, It’s probable that these users fell prey to what’s known as a session cookie hijack attack. Typically initiated through a phishing email, hackers direct victims to a counterfeit login page. Upon entering their credentials, users are prompted to complete a simulated 2FA challenge, which they unwittingly comply with.

The Role of Vigilance

Despite these challenges, I would personally suggest moving away from systems that solely rely on 2FA for authentication. But in the extreme case where abandoning 2FA is not the solution, users must adopt additional measures to enhance their security posture.

Secure Alternative to 2FA/MFA

As we have seen numerous instance of 2FA & MFA getting by passed, enterprises need better methods to secure access to their resources. PureAUTH Secure IAM platform provides Zero Trust -Passwordless access and protects enterprises from following type of attacks

  1. Password Spraying & brute forcing attacks

Slack’s GitHub Exposed – Another MFA Failure

Posted on by Srishti Chaubey

Slack reported suspicious activity on January 9th, 2023 regarding a breach in it’s remotely stored GitHub account. Upon investigation, it was found that tokens of a few Slack employees were stolen, and used to gain access to remote git repositories. The threat actors also downloaded code from private repository. Slack also stated that the threat resulted from a third party vendor, and also assured its users that no customer data is at risk.

Previous Incidents

In March 2015, Slack shared that it had been hacked for over four days in Feb 2015. Additionally, In January 2021, it had a outage for several hours. In a previous blog , we have discussed a past security bug on Slack at December 2022 where passwords were stored in their Android apps in plain text.

Reason and Impact

The attackers were able to gain access due to a security flaw in Slack’s authentication system using Brute Force. Once they had access, they were able to steal the secret seeds (used to generate pseudo random tokens) associated with that organisation’s account and gain access to the private code repositories stored on GitHub. The fact that a brute force attack was successful indicates a security lapse from Slack.

The company claims that the threat actors did not get access to production environment, customer data or Slack resources. Additionally, Slack rotated the concerning tokens with the third vendors, and deployed additional security on their externally hosted GitHub.

About MFA Tokens

In their update what Slack is mentioning as token are MFA seeds or secret keys. These seeds or keys are shared secret between the (Slack’s) server and user’s MFA application. These seeds are used in generation of tokens which are then used to authenticate user in conjunction with passwords.

image credit – Twilio

Twilio has provided here a detailed explanation on how the MFA works with secret keys. Unfortunately Twilio’s Authy was breached and customer’s TOTP secret keys were leaked in the recent past.

Mitigation

Authentication system depending on abusable data like Passwords, Biometrics, or TOTP/HOTP Tokens, of public-keys are insecure by design. Adopting authentication solution which makes use of zero-knowledge factors are resilient to data leakage in case of breach.

PureID‘s Passwordless Authentication platform – PureAUTH eliminates the risk in case of total breach of the authentication parameters it uses to verify users.
