Yorkie-Pro increasingly deployed to fight ransomware threats

Handheld wireless intrusion detection system scans and locates wireless rogue devices that can lead to ransomware

Metuchen - New Jersey, September 02, 2021

Berkeley Varitronics Systems, Inc. (BVS), a leading provider of advanced wireless security, test, safety and cybersecurity solutions and products increases production of Yorkie-Pro handheld wireless intrusion detector to combat growing problem of ransomware threats to critical infrastructure.

Yorkie-Pro wireless intrusion detection system (WIDS) is a handheld receiver designed for wireless security audits of data-sensitive government, law enforcement, military and critical infrastructure facilities. As the U.S. workforce slowly returns back from COVID, an increasing number of PEDs (Personal Electronic Devices) and BYOD (Bring Your Own Device) worker policies has lead to a rise in ransomware attacks upon secure networks within critical infrastructures including healthcare, energy delivery and law enforcement.

"The ubiquity of smart phones, wearables and PEDs can lead to a lax security environment among staff and visitors to secure facilities," says Scott Schober, BVS CEO, author and expert cybersecurity presenter. Schober continues, "malware can piggyback onto almost any device so when BYOD and remote working policies, users and their devices all converge, we get an extremely large attack surface. In addition to best practices, professional wireless threat detection tools must be employed to prevent and catch malware before it takes hold and causes real damage."

Yorkie-Pro was originally designed to scan SCIFs (Secure Compartmented Information Facilities) and secure government, military and law enforcement facilities for hidden bugs and rogue wireless devices that could compromise security integrity. However, TSCM (Technical Surveillance Counter Measure) professionals are extending their services to any critical service facility that deals with confidential data, payment processing or valuable intellectual property due to a recent surge in malware attacks including ransomware.

Since Yorkie-Pro continually scans and logs all nearby cellular, Wi-Fi, Bluetooth and BLE (Bluetooth Low Energy) activity as well as undemodulated 2.4 and 5 GHz RF energy, it becomes a useful tool for detecting devices and patterns of intrusion that either hackers or unsuspecting users leave behind. The handheld unit also creates whitelists to distinguish between known devices and unknown or suspect wireless devices.

Yorkie-Pro detects cellular use up to 150 feet away using the included omni directional antenna but the included wideband (DF) direction finding antenna can pinpoint wireless activity up to 1/2 mile away outdoors (line of sight). This makes Yorkie-Pro especially useful for agents searching for contraband wireless devices and bad actors that use them within their facility as well as hidden GPS trackers and even staff who forget to surrender all of their devices over to security.

Yorkie is available for $4,995 directly from Berkeley Varitronics Systems and also available on
