Armis, has released research, identifying risky assets posing threats to global businesses. Findings highlight risk being introduced to organisations through a variety of connected assets across device classes, emphasising a need for a comprehensive security strategy to protect an organisation’s entire attack surface in real-time.
“Continuing to educate global businesses about the evolving and increased risk being introduced to their attack surface through managed and unmanaged assets is a key mission of ours. This intelligence is crucial to helping organisations defend against malicious cyberattacks. Without it, business, security and IT leaders are in the dark, vulnerable to blind spots that bad actors will seek to exploit.” says Nadir Izrael, CTO and co-founder of Armis.
Armis’ research, analysed from Armis Asset Intelligence Engine, focuses on connected assets with more attack attempts, weaponised common vulnerabilities and exposures (CVEs) and high risk ratings to determine risky assets.
Assets with considerable number of attack attempts
Armis found 10 asset types with high number of attack attempts were distributed across asset types: IT (information technology), OT (operational technology), IoT (internet of things), IoMT (internet of medical things), internet of personal things (IoPT) and building management systems (BMS). This demonstrates that attackers care more about their potential access to assets rather than type, reinforcing need for security teams to account for all physical and virtual assets as part of their security strategy.
Top 10 device types with high number of attack attempts:
- Engineering workstations (OT)
- Imaging workstations (IoMT)
- Media players (IoT)
- Personal computers (IT)
- Virtual machines (IT)
- Uninterruptible power supply (UPS) devices (BMS)
- Servers (IT)
- Media writers (IoMT)
- Tablets (IoPT)
- Mobile phones (IoPT)
“Malicious actors are intentionally targeting these assets because they are externally accessible, have an expansive and intricate attack surface and known weaponised CVEs. The potential impact of breaching these assets on businesses and their customers is also a critical factor when it comes to why these have the highest number of attack attempts. Engineering workstations can be connected to all controllers in a factory, imaging workstations will collect private patient data from hospitals and UPSs can serve as an access point to critical infrastructure entities, making all of these attractive targets for malicious actors with varying agendas, like deploying ransomware or causing destruction to society in the case of nation-state attacks. IT leaders need to prioritise asset intelligence cybersecurity and apply patches to mitigate this risk.” says Tom Gol, CTO of research at Armis.
Assets with unpatched, weaponised CVEs vulnerable to exploitation
Researchers identified a number of network-connected assets susceptible to unpatched, weaponised CVEs published before 1/1/2022. Zooming in on the high percentage of devices of each type that had these CVEs between August 2022 and July 2023, Armis identified list reflected in Figure A. Unpatched, these assets introduce risk to businesses.
Assets with a high risk rating
Armis also examined asset types with the most common high-risk factors:
- Many physical devices on list that take a long time to replace, such as servers and programmable logic controllers (PLCs), run end-of-life (EOL) or end-of-support (EOS) operating systems. EOL assets are nearing end of functional life but are still in use, while EOS assets are no longer actively supported or patched for vulnerabilities and security issues by manufacturer.
- Some assets, including personal computers, demonstrated SMBv1 usage. SMBv1 is a legacy, unencrypted and complicated protocol with vulnerabilities that have been targeted in infamous Wannacry and NotPetya attacks. Security experts have advised organisations to stop using it completely. Armis found that 74% of organisations still have at least one asset in their network vulnerable to EternalBlue, an SMBv1 vulnerability.
- Many assets identified in list exhibited high vulnerability scores, have had threats detected, have been flagged for unencrypted traffic or still have CDPwn vulnerabilities impacting network infrastructure and VoIPs.
- Half of pneumatic tube systems were found to have an unsafe software update mechanism.
Additional research from Armis is available on risky OT and ICS devices across critical infrastructure industries as well as the risky medical and IoT devices in clinical environments
