United Nations ratifies framework to protect people on cash app

2024-11-07
(Press-News.org) As mobile-money services were growing at a rapid clip in the developing world 10 years ago, University of Florida computer scientists and cybersecurity experts Kevin Butler and Patrick Traynor were early sentinels, raising concerns about the lack of security that could lead to real problems for the user. 

In a 2014 study, the two professors from UF’s Department of Computer and Information Science and Engineering, uncovered security vulnerabilities of mobile cash apps, especially in the Global South, where such technologies were becoming essential in the absence of robust banking systems. 

“Our early work uncovered issues of security and privacy when using finance apps,” said Butler, director of the Florida Institute for Cybersecurity Research at UF. “We showed these apps could be hacked, and the consumer has no recourse. We’re often talking about populations where they have very little money to start with, so any type of hack could wipe them out.” 

Fast forward to today, Butler and colleagues developed a comprehensive framework for securing mobile money applications that earlier this year was ratified and endorsed by the International Telecommunications Union, a United Nations specialized agency, marking a significant step toward safer digital financial transactions worldwide. All United Nations member states voted to endorse these recommendations.

 The framework includes 120 detailed recommendations and controls designed to systematically secure every facet of the financial ecosystem, ensuring comprehensive protection for users and transactions. While the recommendations are non-binding, they are widely followed by telecom providers due to their high quality and the interoperability they provide among networks. 

Butler said their work focused on all stakeholders in the digital finance ecosystem, including the user with a smartphone, the phone manufacturer who is responsible for the security of the phone, the cellular networks, base stations, telecommunications providers and third-party regulators. 

“We addressed each of the participants and identified what threats they face and the risks, and we provided recommendations for ensuring those risks are mitigated through the system,” Butler said. 

Mobile transactions through apps (like those used in the U.S., including PayPal, Zelle and others) are very important to people who don’t have easy access to the banking system. In fact, mobile money transactions account for about 59% of the gross domestic product in Kenya, according to a Forbes report. A similar trend is taking place in South America, Asia and India, Butler said. 

Butler and Traynor’s research revealed a variety of vulnerabilities, including with a popular payment app based in India that appeared to use encryption to protect user data but failed to do so securely. They found that the app transmitted sensitive data to its server without encryption, only encrypting it afterward. This lapse in protection could expose users' personal information to potential theft during the unprotected transmission step. 

Another app used encryption but relied on a weak key — a fixed series of eight characters followed by the user's phone and account numbers — making it easy for attackers to decode.  

“We looked at this from many angles and created the list of recommended controls to thoroughly safeguard all parts of the digital finance network,” Butler said.  

With the digital finance security framework complete, Butler said he is working to help deploy the recommendations, meeting with stakeholders in several countries. He recently presented best practices for secure mobile banking systems in Jakarta. He also co-chaired the Security, Infrastructure, and Trust Working Group under the Financial Inclusion Global Initiative, a collaboration involving the United Nations, World Bank, and Bank for International Settlements. 

Additionally, the International Telecommunications Union iis conducting security clinics across Sub-Saharan Africa that incorporate many of the document’s recommendations. Clinics have already been held in Uganda, Zambia, Zimbabwe, and Tanzania, aimed at empowering local stakeholders with the knowledge and tools necessary to enhance the security of mobile money applications.  

“By fostering collaboration and providing targeted training, the International Telecommunications Union is helping to bolster the resilience of the financial ecosystem in these regions,” Butler said.

Could crowdsourcing hold the key to early wildfire detection?

2024-11-07
The 2023 blaze in Lahaina, Hawaii, which claimed more than 100 lives and burned 6,500 acres of land across Maui, is a tragic example of how rapid wildfire spread can make effective response efforts impossible, resulting in the loss of life and property. What if technology could help people detect wildfires earlier? The solution could already be in your pocket: a mobile phone. USC computer science researchers have developed a new crowdsourcing system that dramatically slashes wildfire mapping time from hours to seconds using a network of low-cost mobile phones mounted on properties in high fire threat areas. In computer simulations, the system, FireLoc, detected blazes igniting ...

COVID-19 restrictions altered global dispersal of influenza viruses

2024-11-07
Although travel restrictions and social measures during the COVID-19 pandemic led to a dramatic global drop in seasonal influenza cases, certain influenza lineages in specific regions kept the virus circulating and evolving, according to a new study. This was true in tropical areas with fewer travel restrictions, for example, including South and West Asia. The spread of seasonal influenza is closely tied to social behavior, particularly air travel, and to the periodic evolution of new virus strains that evade immunity from prior infections or vaccinations. In 2020, nonpharmaceutical interventions (NPIs) introduced to combat COVID-19 – such as ...

Disconnecting hepatic vagus nerve restores balance to liver and brain circadian clocks, reducing overeating in mice

2024-11-07
Disruptions between the brain’s master circadian clock and the liver’s internal clock, communicated via the hepatic afferent vagal nerve (HVAN), can lead to unhealthy eating patterns and increased weight gain, according to a new study in mice. The findings identify the neural link as a potential therapeutic target for obesity and metabolic dysfunction related to circadian disruption. In mammals, circadian rhythms are controlled by the suprachiasmatic nucleus (SCN) – a small part of the brain’s hypothalamus that regulates the body’s circadian rhythms. This cycle triggers a feedback loop involving key clock genes that keep ...

Mechanosensory origins of “wet dog shakes” – a tactic used by many hairy mammals – uncovered in mice

2024-11-07
“Wet dog shakes” – a common reflex behavior shared among many hairy mammals and designed to expel water and irritants from their coats – happens when particular mechanoreceptors are activated, researchers studying mice report. Many furry mammals engage in rapid body twists known as "wet dog shakes" to effectively remove water from their fur, as well as to eliminate irritants like tangles or parasites, particularly in areas on the neck and back that are largely unreachable by self-grooming or licking. However, despite the commonality of this behavior ...
