Cyberpion Reveals a Quarter of Fortune 500 Companies Have Exploitable Vulnerabilities in their External IT Network

As companies adopt a distributed IT infrastructure model, there is an increased need for companies to monitor and track the risk exposure created by external and third-party assets

KIRKLAND, Wash. and TEL AVIV, IsraelSept. 14, 2021 — Cyberpion, a cybersecurity pioneer in external attack surface management (EASM), today presented research showing that nearly three quarters of Fortune 500 companies’ IT infrastructure exists outside their organization, a quarter of which was found to have a known vulnerability that threat actors could infiltrate to access sensitive employee or customer data.

Key research findings:

  • 73% of Fortune 500 companies’ total IT infrastructure is external to the organization, of which 24% is considered at risk or has a known vulnerability
    • The total IT infrastructure includes the IT assets that are owned and operated by vendors the Fortune 500 enterprises incorporated into their online footprint
    • These IT assets include servers, cloud storage, CDNs, DNS (Domain Name Servers), email servers and other online elements
  • 71% of total cloud-based IT assets are external to the organization, of which 25% failed at least one security test
    • An example of cloud vulnerability includes cloud storage configured to allow anyone to read or write its contents
  • On average, a Fortune 500 company’s infrastructure contains 126 different login pages for either customer or employee portals or services – the highest number was over 3,000
    • Nearly 10% of these login pages are considered insecure due to the transmission of unencrypted login data, or issues with SSL certificates, which helps ensure that the submission is being sent to the authorized destination
    • 30% allow transmission over HTTP
    • 12% have invalid certificates/encryption
    • Hackers exploiting these logins could access a wealth of sensitive employee or customer data
  • Fortune 500 organizations connect to an average of 951 cloud assets, of which nearly 5% are vulnerable to severe abuse
    • For example, a misconfigured AWS bucket could allow hackers to read or overwrite the data which could be customer PII or application code
    • The largest exposure was well over 30,000 cloud assets

Cyberpion collected these results by performing a cursory single-pass scan of the public and internet-facing assets of every Fortune 500 company in the first half of 2021.

According to Gartner1, “EASM is an emerging concept that is growing quickly in terms of awareness within the security vendor community but at a slower pace within end-user organizations…They help security professionals identify exposed vulnerabilities from known and unknown enterprise assets and prioritize the most critical issues to be tackled…EASM should be part of a broader vulnerability and threat management effort aimed at discovering and managing internal- and external-facing assets and their potential vulnerabilities.”

Traditional third-party risk management solutions have focused exclusively on the vendors and the IT infrastructures that are directly connected to the enterprise. This approach ignores the true scale of the problem and represents only the tip of the iceberg. Third-party vendors have also adopted a distributed IT infrastructure, and have built their applications and services using their own vendors and third parties. Those, in turn, build their solutions upon even more partners. This extensive ecosystem creates an external attack surface that is uniquely appealing to hackers and extremely complicated for enterprises to secure.

Hackers are finding it easier to takeover or exploit third-party vulnerabilities within the enterprise’s ecosystem in order to carry out attacks such as: malicious code injection (Magecart-style attacks), DNS hijacks, or abusing branded enterprise assets. These breaches ultimately lead to data loss, brand reputation damage, and stolen customer data for the enterprise.

“Security teams often can’t effectively defend against attacks stemming from third parties because they lack visibility into the total inventory and volume of assets they are connected to,” said Cyberpion CEO Nethanel Gelernter. “They are unaware of the exposure to these external vulnerabilities, and can’t identify and mitigate against these risks. In addition, the growth of these interconnected assets continues to explode due to trends in cloud-first architectures and digital transformation initiatives, meaning that assessing and protecting the attack surface has become even more challenging over time.”

About Cyberpion
