Is Your Data Safe with USB Security?
Universal Serial Bus, or USB, is a widely used method for transferring data from computer to computer. While it’s an accessible, cost-effective method of moving around files, its widespread presence poses serious security risks.
The primary risk associated with USBs is malware. Malware can spread easily from USB to other devices, giving attackers control of computers and monitoring employee activities. Alternatively, malicious USBs may contain software that will directly attack victims’ systems.
BadUSB infections are typically initiated by an untrained user plugging in a suspicious-looking device that contains code. Once activated, this malicious software can take control of your computer, encrypt all stored data, and demand payment to unlock it.
Additionally, malware can monitor computer activity remotely – creating a new type of cybersecurity risk.
Therefore, it’s essential that all employees comprehend the risks and significance of proper USB security practices. This may involve regularly training employees on how to utilize their USBs safely and ensuring only authorized personnel have access to USB drives.
Additionally, having a comprehensive USB security system in place that monitors and controls the usage of all USB devices is essential. Doing so can prevent unauthorized downloads, data leaks and infections on these storage devices from leaving your organization’s network.
To combat USB infections, the best approach is to deploy a USB scanning kiosk or station that will scan every USB that connects to your company’s network. These stations can then be scheduled to run periodically so any infected USBs are removed before entering the corporate network.
Another essential step is to disable Autorun on all USBs within your organization. This enables programs to run automatically when inserted into a machine, but it leaves it open for hackers to weaponize USBs and use them as vehicles for spreading malware.
For the most comprehensive endpoint security solution, combining DLP and USB security with technical controls and enforcement is the most efficient approach. This involves training all employees on proper USB usage as well as deploying physical security measures along with DLP software featuring USB access control features.

Are Your Devices Vulnerable to USB Threats?
USB threats can have a devastating effect on your system. They have the potential to steal data, infect your network or cause physical damage to hardware. Therefore, it’s essential to understand how these threats operate and how best to safeguard your company against them.
Industrial organizations invest money and effort into firewalls and other security measures to safeguard their systems, but hackers have discovered that USB drives are an easy way to circumvent these defenses. As a result, 52 percent of malware now specifically targets USBs or other removable media when attacking its targets.
According to the 2022 Honeywell Industrial Cybersecurity USB Threat Report, removable media has seen a drastic increase from 32 percent in 2020, which is proof that cybercriminals are actively using them as tools to circumvent various security measures. Furthermore, this raises concerns that operational technology (OT) systems may become particularly vulnerable to these types of attacks since they rely on removable media to connect their computers to external networks.
Therefore, it’s essential for your organization to implement strong protections against USB-borne threats. This includes technical controls, employee training and enforcement, as well as integrated monitoring and incident response procedures.
Furthermore, you can utilize encryption software to safeguard your data before it’s sent over the internet. This is especially essential if your organization has sensitive information that could be stolen or compromised via USB devices.
Even with all these measures in place, some devices may still not be protected by antivirus or don’t have their autorun settings set. This opens the door for an infected device to enter a network and spread the virus across any connected devices that lack these protections.
To combat this, industrial companies need to review their current controls and update their patch cycles. Doing so will help close the MTTR and reduce the risk of new USB-borne malware variants. This should be done alongside real-time detection, integrated monitoring systems and incident response procedures.

Are Your Devices at Risk? Understanding USB Infections
USB infections can take many forms, from ransomware that locks down your system to silent malware that infects silently. To protect against such attacks, ensure your computers have up-to-date antivirus software and don’t use unknown USB drives frequently.
USBs have the potential to deliver malware and be used for other malicious purposes such as data theft/destruction, sabotage and ransom demands. They could even be programmed to spoof network cards, redirect traffic or reprogram human interface devices (HIDs) like keyboards.
These attacks can take several forms, such as accidental USB drive drop incidents or malicious hackers leaving infected USBs around a system or network. These types of incidents are especially damaging to industrial systems that depend on reliable USB power sources.
One of the most devastating viruses was Stuxnet, which infected software at an Iranian uranium enrichment plant and was eventually discovered by security researchers. This presented a major risk for industries and their networks as it could reprogram a device’s internal microcontroller and cause it to behave unexpectedly.
Other USB infections are unintended and occur when people plug in infected USBs into weakly secured systems like Internet cafes or airports. While these can be detected eventually after the infection, there’s no way of knowing how much damage has already been done.
BadUSB malware takes advantage of the USB standard to reprogram USBs so they can be used as keystrokes or commands on a computer, install malware before it boots up, spoof network cards and redirect traffic. Cybercriminals have also been known to send these USBs via mail or trade show giveaways.
As the number of USB infections continues to increase, it is essential that your computers remain protected from them. This can be accomplished through implementing security policies and procedures, installing antivirus software, and blocking any known threats on your systems.

Is USB Authentication the Key to Securing Your Cyber World?
USB security keys, also referred to as U2F keys, offer a new way of safeguarding personal and business accounts without needing additional software or hardware. They’re much harder to hack than older two-factor authentication methods like SMS codes or authentication apps and require no extra steps for protection.
USB security keys are compatible with the FIDO/U2F and WebAuthn standards that most websites support. Furthermore, these USB keys include a fingerprint reader built-in so even if you lose the device, your login details won’t be accessible without a matching finger print.
Add a USB security key to your computer’s keychain or plug it into any USB port and use it for identity verification whenever signing into a website. Doing so helps protect data and prevents hackers from exploiting phishing sites that look legitimate but actually access sensitive information about you.
Security keys come in a variety of sizes and shapes, making them ideal for different uses. Some keys are small and easily portable while others are larger and more robust. When selecting your security key, make sure it supports the authentication standards necessary for your application.
Some of the best USB keys will also feature a fingerprint reader built-in, so that you can verify your identity using your fingerprint. This helps guarantee your data remains secure, especially if sending it over public Wi-Fi networks.
Many cybersecurity professionals recommend physical security keys as the safest form of authentication, since they don’t rely on any third-party technology to generate tokens or solve cryptographic challenges. Furthermore, physical keys can be used to encrypt your data, making it hard for someone else to decipher its files on a device.
The most widely used hardware security key is the FIDO/U2F key, which is compatible with most major websites. However, if you plan to use it for more complex sites or services, consider getting a key that supports additional standards.
Security keys not only keep your data safe, but they can also replace passwords or other traditional forms of two-factor authentication. While security keys are a great way to increase online safety, it’s worth remembering that they may get lost or stolen – which is why it’s essential to back up all passwords and set up extra 2FA methods when enrolling a key.
