Printer Security Vulnerabilities: What you print is what they get

printer security vulnerabilities

Are you aware of the various printer security vulnerabilities? In today’s technologically advanced world, most personal and corporate printers do more than just print documents. They are IoT devices that are capable of much more. But, with these capabilities, come more risks and vulnerabilities. Being connected to the network, and almost every other device on the network, makes printers the perfect entry point for bad actors due to their public accessibility.

IoT printers are vulnerable to hardware attacks – specifically, network implants. These malicious devices sit on the Physical Layer, going undetected by existing security solutions. This can cause a number of perilous consequences which can seriously harm an organization.

Printers are seemingly innocuous devices, which makes them even more harmful since cybersecurity is not as seriously applied to these devices. Due to their apparently harmless nature, they are not typically on the radar of corporate cybersecurity teams. According to a survey by Spiceworks, only 16% of IT industry respondents think that printers are at high risk of a security breach. Furthermore, 43% of surveyed companies ignore printers in their endpoint security approach. It is crucial to be aware of printer vulnerabilities.

Every organization will have multiple printers at the office and are therefore an appealing target for malicious actors. Printers are often a target in cyberattacks on banks, as there are many printer security vulnerabilities-but all organizations are at risk…

Threats

Document theft

Most printers have internal storage where they stow print jobs, scans, copies, and faxes. An attacker targeting a printer can recover these documents and use them to harm the organization, or even sell them on the darkweb for a considerable amount. This data breach can have serious consequences for the victim, including hefty legal fines and a damaged reputation.

Changed settings

An attacker might set out to change the settings on a printer to reroute print jobs in order to obtain confidential information. Changed settings can also allow the perpetrator to open saved copies of documents. Additionally, the settings can be reset to the default settings which wipes any changes made by the organization, including security changes. By altering the settings of the printer, an attacker can cause a crippling data breach.

Eavesdropping

Another way in which a data breach can be caused is whereby the attacker eavesdrops and/or captures documents sent from the computer to the printer. By sitting on the network, an implant can gain access to the network printer traffic and obtain potentially sensitive information.

Network infiltration

By accessing a network-connected printer, the attacker can move laterally across the network to other unsecured devices. This can allow the perpetrator to cause more damage than if they were to just target the printer. If sensitive data is not found on the printer, by infiltrating the network the attacker might discover confidential information elsewhere and the printer simply serves as an access point.

DDoS attack

An attacker might target a printer to incorporate it into a botnet in order to carry out a DDoS attack, causing the printer to stop working. It is simple for an attacker to take advantage of printer vulnerabilities.

Malware installation

Through an attack, a perpetrator can install malware on the printer to control it remotely or gain access to it. This can subsequently result in a data breach or further network infiltration.

Heavy spending on cybersecurity should bring a high return on investment, yet gaps in visibility limit this. Sepio’s Hardware Access Control (HAC-1) solution provides a panacea to gaps in device visibility to ensure you are getting the most out of your cybersecurity investments. HAC-1 integrates with existing solutions, such as NAC, EPS, SIEM and SOAR, to enhance the organization’s cybersecurity posture. HAC-1’s deep visibility capabilities mean no device goes unmanaged; the solution identifies, detects, and handles all IT/OT/IoT devices. Moreover, HAC-1’s policy enforcement mechanism and Rogue Device Mitigation capabilities instantly block any unapproved or rogue hardware. In doing so, ultimately, HAC-1 enables a Zero Trust Hardware Access approach which stops attackers at the first line of defense.

Evidently, printer security vulnerabilities should be a major cause for cybersecurity concern. Printers are often one of the weakest links of an organization. So, what you print is not just what you get; you might be giving an attacker their next pay check.

Sepio’s platform uses a novel algorithm, a combination of physical layer fingerprinting module coupled with a Machine Learning module – providing the sought-after visibility and enforcement level, it is further augmented by a threat intelligence database – ensuring a lower risk hardware infrastructure.

Hardware Assets Control solution for iot security

Sepio Hardware Access Control HAC-1, provides 100% hardware device visibility and improves printer security vulnerabilities.

HAC-1 enables Hardware Access Control by setting rules based on the devices characteristics.

HAC-1 instantly detects any devices which breach the set rules and automatically block them to prevent malicious attacks.

The idea is to Verify and then Trust that those assets are what they say they are.

With greater visibility, the zero-trust architecture can grant access decisions with complete information.

Thus, enhancing the enterprise’s protection within, and outside of, its traditional perimeters.

The Hardware Access Control capabilities of HAC-1, block Rogue Devices as soon as they are detected

Our HAC-1 solution stops an attack at the first instance, not even allowing such devices to make network access requests.

Physical Layer Fingerprinting

Sepio is the only company in the world to undertake Physical Layer fingerprinting . HAC-1 detects and handles all peripherals; no device goes unmanaged.

With this total visibility, a stronger cyber security posture is achieved. There is no longer needed to rely on manual reporting or employee compliance. Sepio manage security and provides answers to questions such as:

  • Do we have an implant or spoofed device in our network?
  • How many IoT devices do we have?
  • Who are the top 5 vendors for devices found in our network?
  • Where are the most vulnerable switches in our network?

Having visibility across all hardware assets provides a more comprehensive cyber security defense.

Reduce the risk of a hardware attack being successful and our private health data being stolen.

Founded in 2016 by cybersecurity industry veterans from the Israeli Intelligence community, Sepio’s HAC-1 is the first hardware access control platform that provides visibility, control, and mitigation to zero trust, insider threat, BYOD, IT, OT and IoT security programs.

Sepio supporting compliance

Sepio Hardware Access Control (HAC-1) solution provides entities with the Physical Layer coverage they need to obtain complete device visibility. And, in doing so, also provides protection against hardware-based attacks.

As the leader in Rogue Device Mitigation (RDM), Sepio’s solution identifies, detects and handles all peripherals; no device goes unmanaged.

HAC-1 fingerprinting technology

HAC-1 uses Physical Layer fingerprinting technology and Machine Learning to calculate a digital fingerprint from the electrical characteristics of all devices and compares them against known fingerprints.

In doing so, HAC-1 is able to provide organizations with ultimate device visibility and detect vulnerable devices and switches within the infrastructure.

In addition to the deep visibility layer, a comprehensive policy enforcement mechanism recommends on best practice policy and allows the administrator to define a strict, or more granular, set of rules for the system to enforce.

When a device breaches the pre-set policy, HAC-1 automatically instigates a mitigation process that instantly blocks unapproved or Rogue hardware.

Furthermore, HAC-1’s RDM capabilities support compliance with Section 8 of the EO, which concerns the government’s investigative and remediation capabilities.

Section 8 focuses on enhancing data collection efforts in order to improve the investigation and remediation processes following an incident. HAC-1 logs all hardware asset information and usage and maintains such data for a period defined by the system administrator.
