China’s eastern Jiangsu province has applied blockchain technology in prison management for parole, commutation and prisoner assessments, a local newspaper reported.

The official Xinhua Daily in Jiangsu reported last week that the blockchain-supported smart prison system used in 21 prisons in the province has been endorsed by the Ministry of Justice, which recommended promoting the idea to the more than 600 prisons nationwide.

According to the report, the platform adopted by the provincial prison authority has more than 800 functions and nearly 1,200 procedures to provide a one-stop solution for the inmate assessment, punishment and rewards system. “The whole process of law enforcement by police will leave online records and 100 per cent of the cases can be traceable [to every step],” it said.

The system managing commutation and parole, for instance, is connected with the courts and procuratorate so that the whole procedure can be handled online, the report added. Commutation and parole approvals will be open to the public on the official website of the Jiangsu prison management authority, as well as the province’s public administration information website.

Corruption and abuse cases in Chinese prisons, which hold about 1.8 million inmates and employ 300,000 guards according to the latest available data from 2012, often stir public anger, and Beijing has been working to root out unjustified commutations and paroles.

Blockchain is a distributed database where information is synchronized and shared by all participants. The data is not owned by any single authority, so the decentralized design enables it to be transparent and tamper-resistant, which could effectively reduce corruption or abuse in the prison environment.

We believe there are important use cases for blockchain in prison, such as inmate management including certification and electronic verification of forms, records, and data requiring action by an inmate; the creation of an inmate-specific contract in a blockchain network to monitor, manage and reward the behavior of an inmate; and reducing the costs of the traditional prison banking system, among many others.

Blockchain ties together the previously discreet domains of prison commissary providers, correctional banking systems, jail management systems (JMS) and the inmate communications services (ICS) providers.

meshDETECT® is pleased to announce that it has recently received a notice of allowance from the United States Patent and Trademark Office (USPTO) for U.S. Patent Application Number 15/700,144 entitled “System and method for controlling, monitoring and recording of wireless telecommunications services in penal institutions.”

A notice of allowance from the United States Patent and Trademark Office is a written notification that a patent application has cleared internal review and is pending issuance.

This fourth patent further expands our Secure Prison Cell Phone Solutions™ intellectual property portfolio and solidifies our position as the prime innovator in the prison mobile device space. The claims in this latest patent are directed toward monitoring an inmate’s mobile device use and then remotely modifying inmate access to features and functions based on the detection of tampering with or prohibited usage of the device.

As more correctional facilities deploy wireless communications devices to inmates, these devices have the potential for criminal mischief if not closely monitored and strictly controlled. Prison authorities need timely notification of misuse or tampering as well as the ability to restrict or disable critical device features and functions, on an automatic or ad hoc basis.

Additionally, correctional facility staff need the capability to take immediate action to mitigate an individual inmate’s breach of the device use rules, or even restrict the functionality of all of the prison populations’ devices in the case of emergency situations such as a riot or lock down.

Brian Byrne, Managing Partner of meshIP, LLC commented, “With this fourth patent, we now have intellectual property which covers the four key aspects of secure wireless inmate calling – system, application, device management and now device security. There continue to be many industry announcements regarding personal communications device roll outs in prisons and jails, but we believe we are the only inmate communications services company with the intellectual property portfolio protecting these four core elements of the rapidly emerging inmate mobile device market.”

Update: The patent (US10,278,076) was issued on April 30, 2019 by the United States Patent Office. You can view the patent here: Fourth meshDETECT patent.

Aisto® is a new, patented, blockchain enabled service from meshIP®. More than just the underlying technology for Bitcoin or other crypto tokens used to facilitate transactions, the blockchain has many practical uses, including within the corrections industry.

A blockchain definition: A blockchain is a database that is distributed among multiple computing devices. A blockchain is formed from blocks, with each block having information related to a transaction and linking the block to a prior block in the chain. The computing devices can each have respective copies of the blockchain, so that no centralized or official copy of the blockchain exists and no computing device is trusted more than any other computing device. When a user initiates a transaction, some or all of the computing devices can verify the transaction. After verifying the transaction, the computing devices can include information related to the transaction into the respective copies of the blockchain. This can be more robust and secure than many other approaches. At a high level, blockchain technology allows a network of computers to agree at regular intervals on the true state of a distributed ledger. The ledger is distributed across many participants in the network — it doesn’t exist in one place. Instead, copies exist and are simultaneously updated with every fully participating node in the ecosystem. A block could represent transactions and data of many types.

Innovation, especially technology innovation, requires a willingness to challenge accepted approaches to problems as well as entrenched industry “truths”. This nontraditional thinking is best captured by a quote from hockey great Wayne Gretzky, “I skate to where the puck is going to be, not where it has been.”

Back in June of 2011, we issued a press release announcing the introduction of the meshDETECT Secure Prison Cell Phone Solution. In the press release we said, “The meshDETECT™ secure cell phone platform devalues the contraband value of the smuggled prison cell phone and immediately creates a safer, more secure, and controllable environment for both corrections officials and detainees.” Since then we have written extensively about why contraband cell phones are a problem of both supply and demand. And about how enhanced access to telecommunications services has the proven, significant, additional benefits of reducing recidivism, improving detainee behavior and increasing officer safety.

This was not the conventional view on solving the significant and growing problem of contraband cellphones in prison at the time. In fact, many in the industry thought we were crazy for proposing giving detainees a “cell phone”.

However, according to the August 2014 issue of eTechbeat, an online magazine published by the National Law Enforcement and Corrections Technology Center (NLECTC); the Indiana Department of Correction is now allowing inmates in two of their facilities to use cordless phones in their cells in an effort to stem recidivism and contraband cellphones and encourage better behavior while incarcerated.

In the article, INDOC Deputy Commissioner James Basinger is quoted saying, “Inmates are allowed to walk around with the phones and take them to their cells to have a phone conversation out of hearing from other inmates, which could lessen inmates’ desire for cellphones. Although inmates use contraband cellphones for criminal activity, not all inmates want them for that purpose. I think it’s a way to combat the contraband cellphone problem. In my opinion, part of the interest in cell phones is you can talk to family and friends in a private setting and are not standing up at the wall with other inmates. We want to encourage communication. Inmates with more contact with family and friends may behave better. It’s all about improving communication . It seems like a good way to improve their reintegration. If they keep connected to the family it might make them stay out of prison when they get out. We are trying to get them out and to be productive.”

Sound familiar?

Cordless phones are not a scalable or cost effective solution, but we believe this is yet another data point proving what we have been preaching. Innovation can be a lonely skate, but eventually you get to the puck.

With Global Tel*Link all but announcing at the recent Corrections Technology Association Annual Meeting its intention to offer mobile services in prisons, now may be the time to consider the best technology architecture for such deployments for those prison administrators who see the potential benefits of a secure prison cell phone solution.

There are essentially two ways to provision wireless personal communication devices, such as prisoner tablets, in a prison environment. In its presentation, Global Tel*Link stated that it has chosen to deploy service using WiFi to provide wireless connectivity. We think there are some significant operational challenges and, more importantly, serious security risks in this approach.

Security Risks

There are two main security risks, as highlighted by the recent news articles below. The first is the potential for intentional hacking of the system, either internally by tech savvy prisoners, or externally by those determined to defeat the WiFi security controls in order to gain or grant unfettered access to Global Tel*Link services, connected prison systems (commissary and trust accounts, etc.) or the unfiltered internet. A very real challenge with the decision to deploy a prison WiFi network is external hackers “wardriving” the system from outside the prison facility in order to accomplish this.

The second risk is the unintentional granting of access to the internet due to incompetence, human error and service misconfiguration.

In either case, the deployment of a local access wireless network via WiFi means that a single security breach, password hack or incompetent admin may result in unsecured and unmonitored access to internal prison systems and the outside world for all devices on the network.

In contrast, meshDETECT uses the traditional telco mobile network to provide secure voice and media services. Any breach, should it occur, is limited to a single device. If a device is hacked, a risk Global Tel*Link will also have to manage, one detainee may benefit; but no one can hack AT&T, Verizon, etc. in such a way to give all the meshDETECT mobile devices deployed in a prison unfettered access to the internet, or unmonitored calls to harass outside parties and plan crimes.

Technology choices in the deployment of a secure prison mobile access network service must focus on security, not profitability.

Operational Challenges

Now lets look at the operational challenges associated with deploying WiFi within a prison facility:

• Low powered – hand held devices maximum output is normally 0.4 Watt.

• Signal can suffer interference from other devices such as two way radios used by staff.

• Best when there is line of sight between transponders.

• Does not penetrate solid mass – concrete, brick, metal – the less porous the material the shorter the range and the slower the speed. Prison construction is high density blocks and cell doors are often clad in metal with metal surrounds.

• Tinted / reflective glass contains metal fragments resulting in drop in signal strength.

• Security fencing can act as a Faraday cage and ground the signal.

It is clear that achieving adequate WiFi signal coverage and application data throughput at a reasonable cost of installation is a challenge in this unique environment. Ongoing equipment maintenance expense as well as repair cost due to vandalism must also be considered when looking at the total cost of this approach.

In contrast, as evidenced by the high number of contraband devices and continued use of smuggled cell phones in jails and prisons globally, cellular signal strength and coverage is typically more than adequate, with no onsite equipment required. Additionally, 4G LTE (and soon 5G) cellular may be much faster than a WiFi network with an undersized or overburdened connection to the Internet (designed for coverage versus designed for capacity).

Real World Examples

Securus Finally Admits The Risks Of WiFi Deployment In Prisons

With the recent launch of Securus Technologies’ new inmate tablets utilizing a nationwide cellular network, their press release confirms our analysis and assertions regarding the operational inadequacy and security risks  of deploying WiFi in prisons detailed above. This blog post was written eleven years ago on June 6, 2013.

From the press release:

“Because of the complex implementation requirements in corrections settings, deploying tablet technology can take months, quarters, even years to fully implement, but the infrastructure with our new tablet technology allows for quicker and cost-effective deployment”

“Currently, tablets rely on a complex, on-site setup to connect to cloud-based services, which is costly and time-consuming. EVOTAB and Officer T80 tablets directly connect to a cloud platform using a secure cellular network, which is faster, more secure, and less hardware intensive.”

Mich. DOC updates policy after inmates rig tablets to conduct ‘criminal’ activity

Overall, since October 2024, the Department of Corrections has found that about 5% of the 24,000 JPay tablets, or about 1,200, were compromised after inmates enabled Wi-Fi on the devices, had them in an unauthorized unit or had unauthorized apps.

“(Inmates are) watching movies. They’re watching pornography. They’re communicating with family and or gang members outside the prison system,” Osborn told The Detroit News. “With these tablets in this jailbroke status, they can do whatever the hell they want.”

The Department of Corrections works to find and remove compromised tablets and identify contraband, such as Wi-Fi sticks, used to rig them for internet access.

New Wi-Fi Takeover Attack—All Windows Users Warned To Update Now

Microsoft has confirmed a new and quite alarming Wi-Fi vulnerability in Windows, which has been rated 8.8 out of 10 in terms of severity using the Common Vulnerability Scoring System. The vulnerability, assigned as CVE-2024-30078, does not require an attacker to have physical access to the targeted computer, although physical proximity is needed. Exploiting this vulnerability can allow an unauthenticated attacker to gain remote code execution on the impacted device. What’s perhaps most concerning, though, is that this Wi-Fi driver security flaw affects all supported versions of the Windows operating system.

WiFi vulnerability may leave millions of devices open to ‘frag attacks’

A security researcher known for pointing out faults in WiFi security has discovered another vulnerability. The newly unearthed flaws, known as “frag attacks,” are believed to be widespread as they stem from the WiFi standard, with some bugs dating back to 1997. While several additional vulnerabilities are caused by programming mistakes in WiFi products and affect every WiFi device, Belgian security researcher Mathy Vanhoef wrote on his blog.

Theoretically, if exploited, the vulnerabilities would allow an attacker within radio range to steal user information or attack devices. But, the chances of the flaws being abused should be low as the attacks require user interaction or uncommon network settings.

Breaking down how they work, Vanhoef explained that several of the flaws can be abused to “easily inject” plaintext frames into a protected Wi-Fi network,” along with certain devices accepting “plaintext aggregated frames that look like handshake messages.” This can be used to intercept traffic by tricking the victim into using a malicious DNS server, the researcher noted. In experiments, Vanhoef found that two out of four tested home routers were affected by this vulnerability, along with several IoT devices and some smartphones.

Other vulnerabilities are linked to the process by which the WiFi standard breaks and then reassembles network packets, allowing an attacker to siphon data by injecting their own malicious code during this operation.

A Flaw in Billions of Wi-Fi Chips Let Attackers Decrypt Data

Billions of devices—many of them already patched—are affected by a Wi-Fi vulnerability that allows nearby attackers to decrypt sensitive data sent over the air, researchers said on Wednesday at the RSA security conference. Affected devices include iPhones, iPads, Macs, Amazon Echos and Kindles, Android devices, and various Wi-Fi routers.

The vulnerability exists in Wi-Fi chips made by Cypress Semiconductor and Broadcom, the latter a chipmaker Cypress acquired in 2016. The affected devices include iPhones, iPads, Macs, Amazon Echos and Kindles, Android devices, and Wi-Fi routers from Asus and Huawei, as well as the Raspberry Pi 3. Eset, the security company that discovered the vulnerability, said the flaw primarily affects Cypress’ and Broadcom’s FullMAC WLAN chips, which are used in billions of devices. Eset has named the vulnerability Kr00k, and it is tracked as CVE-2019-15126.

Manufacturers have made patches available for most or all of the affected devices, but it’s not clear how many devices have installed the patches. Of greatest concern are vulnerable wireless routers, which often go unpatched indefinitely.

Serious flaws leave WPA3 vulnerable to hacks that steal Wi-Fi passwords

The next-generation Wi-Fi Protected Access protocol released 15 months ago was once hailed by key architects as resistant to most types of password-theft attacks that threatened its predecessors. On Wednesday, researchers disclosed several serious design flaws in WPA3 that shattered that myth and raised troubling new questions about the future of wireless security, particularly among low-cost Internet-of-things devices.

Every Wi-Fi network at risk of unprecedented ‘Krack’ hacking attack

Every Wi-Fi connection is potentially vulnerable to an unprecedented security flaw that allows hackers to snoop on internet traffic, researchers have revealed.

The vulnerability is the first to be found in the modern encryption techniques that have been used to secure Wi-Fi networks for the last 14 years.

In theory, it allows an attacker within range of a Wi-Fi network to inject computer viruses into internet networks, and read communications like passwords, credit card numbers and photos sent over the internet.

The so-called “Krack” attack has been described as a “fundamental flaw” in wireless security techniques by experts. Apple, Android and Windows software are all susceptible to some version of the vulnerability, which is not fixed by changing Wi-Fi passwords.

“It seems to affect all Wi-Fi networks, it’s a fundamental flaw in the underlying protocol, even if you’ve done everything right [your security] is broken,” said Alan Woodward of the University of Surrey’s Centre for Cyber Security.

Wi-Fi software security bug could leave Android, Windows, Linux open to attack

In an e-mail today to the Open Source Software Security (oss-security) mailing list, the maintainer of wireless network client code used by Android, the Linux and BSD Unix operating systems, and Windows Wi-Fi device drivers sent an urgent fix to a flaw that could allow attackers to crash devices or even potentially inject malicious software into their memory. The flaw could allow these sorts of attacks via a malicious wireless peer-to-peer network name.

The end result is that an attacker could corrupt information in memory, causing wpa_supplicant and Wi-Fi service to crash; a crafted SSID could essentially be used as a denial-of-service attack on affected devices simply by sending out responses to Wi-Fi probe requests or P2P network Public Action messages. But it could also expose memory contents during the three-way handshake of a peer-to-peer network negotiation (the GO negotiation) or potentially allow for the attacker to execute code on the target.

Military Cuts Guantanamo Bay WiFi After Alleged Threat by Anonymous

The Guantanamo Bay detention camp is losing all access to wireless internet and social networks due to hacking threats.

U.S. military officials have blocked access to wireless internet and social networks like Facebook and Twitter at Guantanamo Bay because it fears that international hacking group Anonymous will launch an attack to disrupt services at the naval base.

Anonymous launched a global online protest to mark the 100th day of the hunger strike by Guantanamo Bay prisoners. The detainees have been protesting their living conditions and indefinite detention at the base.

The U.S. military said it has been receiving online hacking threats amid the hunger strike, which were allegedly from Anonymous.

Prisoners Accessed Internet Through Faulty Computer Kiosks

Prisoners in privately run Mt Eden Corrections Facility were able to access the internet through faulty computer kiosks a security review of public sector computer systems has found.

The security breach was one of 12 “weak points” identified in Government Chief Information Officer Colin McDonald’s review of the security of 215 publicly accessible state sector agency IT systems released this morning.

Serco, the company which operates Mt Eden said that on November 26 last year, “an administrative error made it possible to open a web browser session” on kiosks provided to prisoners to allow them to “take responsibility for organizing their day-to-day lives and helps to develop literacy and numeracy skills”.

Serco’s Director of Operations Scott McNairn said the error “allowed for limited access to the internet, policed by a web filter which blocked access to inappropriate sites”.

“No email, social media or adult sites were accessed.”

The internet access was “limited” and “at no time was it possible to access any other systems or information”.

Serco has not said how long prisoners were able to access the internet for.

Mr McNairn said the company had improved security for the kiosks and was “confident” that the likelihood of further problems was “extremely low”.

Jailed Hacker Hacks Prison Network

It’s almost comical, but an incarcerated hacker has hacked into his prison’s computer network.

According to Naked Security (Sophos), Nicholas Webber, who operated the GhostMarket.Net cybercrime website, signed-up for the prison’s IT class. Webber, who was 18 at the time of his arrest for bank frauds and identity theft scams, apparently go onto the network but was unable to access personal information files.

The prison issued a statement to the Register: “At the time of this incident in 2011 the educational computer system at HMP Isis was a closed network. No access to personal information or wider access to the internet or other prison systems would have been possible.”

The incident, which occurred in 2011, only came to light because of a wrongful termination suit by the instructor leading the class.
