The recent case of U.S. Army Sergeant Jian Zhao highlights the growing risk of smartphone-enabled data breaches and the urgent need for advanced wireless security measures. According to the U.S. Department of Justice, Zhao allegedly photographed classified military documents using his smartphone and transmitted sensitive data to unauthorized contacts overseas. While at Joint Base Lewis-McChord, Zhao reportedly used encrypted messaging platforms to communicate and share sensitive national defense information with unauthorized personnel, significantly endangering national security. Zhao’s Smartphone Espionage According…

Wireless communication has become the backbone of modern connectivity, but its ubiquity brings an ever-growing set of vulnerabilities. The latest data highlights an alarming trend: the number of wireless-related Common Vulnerabilities and Exposures (CVEs) continues to increase annually. The chart below shows that the cumulative count of wireless-related CVEs has skyrocketed since tracking began in 1998. A staggering 716 new wireless CVEs appeared in 2024 alone, accounting for 20% of all wireless-related CVEs recorded over the past 27 years. That…

I’ve been using a Samsung Galaxy S21 Ultra for the past three years, and up until yesterday, it had served me well. But then, I woke up to a frustrating surprise—despite being plugged in all night, my phone was stuck at 12% battery. Even worse, a message on the screen read: "Charging halted because battery temperature is too low for safe charging." That was odd because my phone wasn't cold—it was around 70°F (21°C). I unplugged and replugged it, switched…

Organizations today depend on wireless technologies such as Wi-Fi, Bluetooth, and cellular networks to maintain seamless operations. As wireless communication continues to expand, so do the associated security challenges. Many organizations rely on network-based controls, including Network Access Control (NAC), logs, and inventory scans, to protect sensitive data and network integrity. While these solutions are necessary for mitigating particular Wi-Fi threats, they lack the broad coverage and real-time threat mitigation capabilities of Wireless Airspace Defense solutions like Bastille. The Role…

In the modern corporate environment, Bluetooth Low Energy (BLE) is increasingly common in wireless communications for IoT devices, medical equipment, and consumer electronics. People come into the office wearing fitness trackers, wireless headphones, and hearing aids. However, while BLE is convenient for its power savings, ease of use, and efficient data transfer, it introduces vulnerabilities that attackers can exploit to exfiltrate sensitive data from BLE-enabled devices. Bastille Networks provides comprehensive protection against these threats by detecting, identifying, and mitigating BLE-based…

What You Need to Know About Apple's Latest Security Update Apple has released crucial security updates to address multiple vulnerabilities in AirPlay, the company’s widely used wireless media-sharing protocol. The Oligo Security research team identified these vulnerabilities, which pose significant risks, including denial-of-service (DoS) attacks and Remote Code Execution (RCE), which could allow attackers to gain unauthorized control over devices. Understanding the Impact The discovered vulnerabilities impact a broad range of Apple platforms, including: macOS (MacBooks, iMacs, and Mac Mini)…

What Happened On Friday, WhatsApp announced that a sophisticated hacking operation linked to Paragon’s Graphite spyware targeted its users. According to Meta's security team, the threat actors employed a "zero-click" exploit to compromise user accounts without any interaction.  "WhatsApp has disrupted a spyware campaign by Paragon that targeted a number of users, including journalists and members of civil society," a company spokesperson told The Guardian. "We've reached out directly to people who we believe were affected. This [incident] is the…

In today’s connected enterprise, a wide range of wireless devices – from authorized network hardware to personal technologies – pose a growing and often invisible security risk. Attackers can exploit these devices to infiltrate networks, making comprehensive wireless security essential for organizations across all sectors. From corporate data centers and cloud infrastructure to classified environments, unmonitored wireless devices can be gateways for data breaches, eavesdropping, and unauthorized access. Bastille Networks offers a cutting-edge solution designed to secure the entire wireless…

As the threat landscape evolves, insider threats remain a significant challenge for Chief Information Security Officers (CISOs) and cybersecurity teams. Insiders, including employees, contractors, or trusted partners, can misuse privileged access to harm organizations, and the growing use of wireless devices, such as smartphones, laptops, and IoT gadgets, adds a layer of complexity to this challenge. “Insider Threats” today include compromised systems and user devices with RF interfaces. Wireless technologies have expanded the attack surface, creating opportunities for insider threats…

On December 17, 2024, Brian Contos spoke with Brett Walkenhorst, Bastille Networks's Chief Technology Officer, recording a quick Ask Me Anything video about the recent wireless attack that Veloxity disclosed. The conversation explores the "Nearest Neighbor Attack," an innovative wireless attack strategy highlighting how attackers bypass traditional proximity-based security assumptions. It delves into the attack's mechanics and implications and discusses how Bastille Networks’ solutions address these challenges. Volexity states, "The Nearest Neighbor Attack effectively amounts to a close access operation,…
