Hackers are trying to attack big companies. Small suppliers are the weakest link
Cybersecurity vulnerabilities in small and medium sized businesses in the defence industry are leaving the companies themselves – and larger organisations further up the supply chain – vulnerable to cyber attacks.
Researchers at cybersecurity company BlueVoyant examined hundreds of SMB defence company subcontractor firms and found that over half of them had severe vulnerabilities within their networks, including unsecured ports and unsupported or unpatched software, making them vulnerable to cyber attacks including data breaches and ransomware.
With the defence industry a prime target for cyber criminals – including state-backed hacking operations attempting to steal intellectual property and other sensitive information – attackers are ready to exploit any weakness they can to gain access to networks.
It can be relatively simple for attackers to gain remote access to these services if they’re only protected by default or weak credentials, while it’s also possible to for attackers to gain access to these services via phishing attacks.
The rise of remote working over the last year has also meant that remote access and cloud services have become a popular means of network entry for cyber criminals, as it’s less likely that their activity on the network will be detected as suspicious.
Researchers also found that many of the companies examined were running unpatched or unsupported software, making them vulnerable to cyber attacks which exploit known vulnerabilities – and something they suggests means there’s an absence of a patch management strategy.
Cyber criminals regularly take advantage of known vulnerabilities in an effort to gain access to networks – and in the case of the defence industry, a small contractor being compromised could lead to a larger company on the supply chain being subject to cyber attacks.
“A simple compromise of a valid email address can serve as a great vector to spread a malicious attachment throughout supply chain partners or simply victimize a less prepared contractor to get a foothold in the chain and work their way up-stream,” Austin Berglas, global head of professional services at BlueVoyant told ZDNet.
It’s often difficult for smaller companies to stay on top of cybersecurity and there’s a arguement that larger organisations should play a role in helping their supply contractors secure their networks – because by providing this help, not only do they protect their contractors from malicious hackers, they’re also ultimately helping to protect their own networks.
“Empowering contractors to secure the supply chain, implementing continuous monitoring, and proactively identifying threats will help secure the defence industrial base and ensure the safety of a vital national security asset,” said Berglas.
