Quarter of Fortune 500's External IT Assets Are a Cyber Risk

The external attack surface of Fortune 500 companies contains known, exploitable vulnerabilities and security issues, according to new research from Cyberpion.

The Israeli startup compiled its findings from a “single-pass scan” of the public and internet-facing assets of every Fortune 500 company in the first half of 2021.

Nearly three-quarters (73%) of these organizations’ IT infrastructure is now located externally, but this outsourcing trend appears to have created a significant visibility gap. Some 24% of these assets are considered risky or have a known vulnerability, Cyberpion claimed.

This includes a quarter (25%) of externally hosted cloud-based assets that failed at least one security test, such as misconfigured storage.

The report also claimed that the average Fortune 500 firm has 126 different login pages for customers and employees — but 10% of these allow data transmission over unencrypted HTTP or have invalid certificates.

Fortune 500 firms also connect to an average of 951 cloud assets, but almost 5% of these are vulnerable to severe abuse, Cyberpion claimed. This includes AWS buckets misconfigured, which could allow hackers to read or overwrite customer data or code.

The vendor warned that attackers could take advantage of these gaps in visibility and protection to launch Magecart-style attacks, DNS hijacks or brand abuse — resulting in financial and reputational damage.

“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 Gelertner.

“They are unaware of the exposure to these external vulnerabilities and can’t identify and mitigate ..
