AT&T deepened its partnership with EV maker Rivian, confirming its 5G network will power connectivity inside its R2 model, which is slated for availability from 9 June.

The collaboration builds on a relationship dating to 2023, when AT&T became the connectivity provider for Rivian vehicles across the US and Canada.

With the R2 coming to market, the arrangement expands to cover the automaker’s next-generation platform, ensuring its more affordable mass-market model arrives with the same always-on network backbone as its predecessors.

The operator stated its 5G infrastructure will support faster over-the-air software updates, richer infotainment and real-time services which enable the R2 to improve performance and personalisation over time.

“Connectivity is increasingly central to how vehicles are designed, delivered, and improved,” stated Matt Harden, VP of connected solutions at AT&T.

At an automaker technology conference in the US state of Michigan, AT&T also revealed an expansion of its connected car platform in collaboration with Cisco and LiveOne, the parent of Slacker Radio.

The three-way arrangement is designed to simplify how automakers integrate premium entertainment into connected vehicles. AT&T’s wireless network provides the backbone, Cisco contributes multi-party billing infrastructure through its SIM management platform, and LiveOne will be supplying personalised audio content ranging from curated playlists to live programming.

Rather than requiring each automaker to negotiate separate connectivity deals with individual content providers, AT&T noted its platform acts as a single integration layer.

LiveOne joins existing AT&T partners including iM Media Labs and SiriusXM as part of a content ecosystem now reaching more than 60 of the world’s top automotive brands.

Ex-Deutsche Telekom executive Abdu Mudesir resurfaced at US rival Verizon as EVP and president of the operator’s global networks, platforms and technology (GN&T).

The move to Verizon pits Mudesir in direct competition with T-Mobile US, which is majority owned by Deutsche Telekom.

Mudesir will succeed 30-year veteran Joe Russo, who is retiring over the coming months. He will sit on an 11-member leadership team reporting directly to CEO Dan Schulman.

Russo is currently EVP and president of global networks and technology.

A representative for Verizon told Mobile World Live (MWL) the company hired Mudesir following a thorough global search.

“He has a brilliant track record in building 5G capabilities, scaling fibre architecture, and is a recognised pioneer in Open RAN, cloud infrastructure, and AI-driven network automation,” the representative stated.

Mudesir, who served as Deutsche Telekom’s head of product and technology, left the company abruptly in late March 2026 after eight years in various roles.

Verizon noted it is still finalising the exact dates for the transition, but stated Russo remains fully in charge of GN&T for now and will be staying through Q1 2027 to ensure a seamless transition.

“Abdu is obsessed with the customer experience and network excellence,” Schulman said in an internal announcement to employees. “He will help drive the convergence of Network, Platforms, Technology, Products and AI, using our unrivaled connectivity and the transformative power of AI to define what comes next for our business and the customers we serve.”

Wirtgen Group is actively developing automated road construction vehicles as stepping stones for full autonomy using some of the same technology stack as parent company John Deere.

During a recent demonstration of its roadbuilding machinery at the company’s North American headquarters in the US state of Tennessee, company executives outlined the benefits of its specialised heavy machinery for road building.

Demand for roads and infrastructure keeps rising while contractors juggle labour shortages, climbing material costs, tighter project timelines and shorter paving seasons.

In the US alone, the construction industry is expected to need nearly 700,000 additional workers by 2031 just to keep pace with demand.

About 40% of the four million miles of roadways across the US are currently rated in poor or mediocre condition.

“As we talked with our customers, we learned a few things about some of their business challenges, which is simply to do more with less,” said Craig Lamarque, VP and head of digital products at Wirtgen America. “Every day our customers are responsible to ensure the safety of every person on absolutely every job site”.

“And they have to do that with increasingly less skilled and less experienced personnel.”

Lamarque explained customers must complete a greater number of projects on tighter timelines to stay profitable while coping with issues with materials, sustainability pressures, labour shortages, and the need to stay on budget and on schedule.

Wirtgen Group responded by introducing digital tools to help address those challenges.

He said Wirtgen’s digital strategy centres on three pillars: connected support to maximize uptime, job site intelligence to expose inefficiencies and improve decision-making, and smart automation to boost machine performance.

Those capabilities are embedded across its road construction equipment lineup and are supported by hardware and software in collaboration with John Deere.

A legacy built on family names

The Wirtgen Group was a privately held German company before it was acquired by John Deere in 2017.

Earlier in its history, the Wirtgen Group bought asphalt paving company Vogele (in 1996) ahead of purchasing soil and asphalt compaction company Hamm three years later. Vogele was established in 1836, one year prior to John Deere.

Kleemann was acquired in 2006, which expanded Wirtgen’s reach into mineral processing with mobile crushing and screening plants.

The Wirtgen Group bought a 70% stake in Benninghoven in 2014, adding asphalt mixing plants to the ecosystem and enabling Wirtgen to offer the entire cycle of road construction equipment from mixing and paving to milling and recycling.

Wirtgen America was established in 1984 and now includes 300 employees across the Tennessee campus.

“Every one of those names of the brands is a family name, much the same as Deere,” said Wirtgen America president and CEO Jim McEvoy. “From that standpoint, we have a long legacy of being early in these markets, being leaders in these markets and being very innovative in these product spaces.”

Here’s a look at three of the roadbuilding machines and technologies showcased in Tennessee across asphalt milling, paving and compaction.

Wirtgen milling machine
The milling machine removes old asphalt or concrete surfaces while using automation and digital guidance technologies to improve precision, efficiency and performance tracking. It is designed for high-output work on freeways, highways, airports and other major infrastructure projects.

The W210XF is equipped with a 2.5 metre-wide cutter drum which removes asphalt and concrete prior to loading the material into a truck. It uses automation and digital guidance technologies across eight cameras to improve precision, efficiency and machine performance tracking.

“Simple diagnostics, intuitive instructions on the display and backup components built into the machine make it easy to keep going,” Lamarque said.

WPT Milling documents job and machine data for billing and emissions tracking. Smart Level Pro is a fully integrated differential milling system which scans the surface about to be milled.

The process begins with a high-speed survey scan of the existing road surface, either by the customer or a third-party surveyor, without closing the road. The resulting digital model is then georeferenced and logged using GNSS.

After scanning, the road profile is refined to meet specifications, then uploaded to the John Deere Operations Centre and Work Planner, where cutting depths can be checked in advance which saves time compared with milling first and verifying later.

Utilising two John Deere StarFire receivers connected by cellular service, Lamarque said the mill goes to work, “precisely milling the design depth and slope, leaving the best possible surface”.

StarFire GNSS Guidance is Deere’s satellite technology which helps machines maintain highly accurate positioning, alignment and paving guidance throughout the roadbuilding process.

Mill Assist is an automated system on the milling machine that uses real-time machine data to optimise performance, improve efficiency, and reduce fuel consumption and emissions.

Vogele asphalt paver
The asphalt pavers are packed with highly specialised automation, levelling and material handling technologies.

Smart Pave is an advanced digital control and automation system developed by Vogele for its asphalt road pavers. AutoTrac technology helps the paver hold its direction of travel and paving width with precision.  

RoadScan is Vogele’s proprietary, non-contact thermal imaging and temperature measurement system mounted directly to the asphalt paver.

Hamm asphalt roller
The double-drum asphalt roller machine compacts fresh asphalt to the target density required for long term durability, using real-time density monitoring and intelligent compaction technology to hit the mark.

It focuses on preventing over-compaction, maximising operator efficiency and providing proof of compaction quality to contractors, state and federal authorities.

The roller uses a combination of vibration and oscillation to compact material to the desired density. Smart Compact Pro and Track Assist help road crews compact more efficiently, cost-effectively and safely while also meeting intelligent compaction specifications.

Intelligent compaction is data collection of the roller using GPS compact mapping, temperature sensors which map and report asphalt surface temperature and an accelerometer sensor that reports stiffness.

From automation to autonomy
Jason Ambroson, VP and managing director of Wirtgen International, explained running the same technologies, connectivity and data sensors across the various roadbuilding machines enables customers to be more productive using fewer employees and fewer resources.

“We are moving from automation to autonomy,” he said.

That trajectory of connecting machines, data and operators into a single intelligent system was what the Tennessee demonstration was ultimately built to show.

The Federal Communications Commission (FCC) opened its first spectrum auction in four years, putting 200 licences on the block for bidding by AT&T, T-Mobile US, Verizon and possibly SpaceX.

Auction 113, formally known as the AWS-3 auction, includes licences covering frequencies in the 1695–1710 MHz, 1755–1780 MHz and 2155–2180 MHz bands.

Those frequencies were originally auctioned to Dish Network, which is now part of EchoStar, in 2014 but never made it into service after a series of defaults and bid withdrawals left them sitting unused in the FCC’s inventory for over a decade.

In 2015, Dish Network affiliates Northstar Wireless and SNR Wireless surrendered a number of spectrum licences worth $3.5 billion after a dispute with the FCC over discounts.

Last week the FCC and EchoStar reached an agreement which included the latter dropping a lawsuit it filed in a US Court of Appeals over the defaults by Northstar and SNR.

Proceeds from the auction which started yesterday (2 June) will fund the FCC’s secure and trusted communications networks reimbursement program, commonly known as “rip and replace”. It seeks to remove equipment by Huawei and ZTE from US communications networks.

The licences cover territory home to more than 100 million people across 48 states, and two US territories. The auction makes over 1.4 billion MHz-POPs available.

FCC chair Brendan Carr did not hold back in marking the occasion.

“Finally! The FCC is back in the game,” he stated while calling spectrum auctions “the lifeblood of licensed wireless service”.

Carr noted getting this auction moving was the first item the FCC voted on at his first meeting as chair.

“More spectrum means more building, lower prices and stronger competition,” he added.

The auction fits into the FCC’s broader Build America Agenda, which is targeting the delivery of 800 megahertz of spectrum by 2034 under the framework set out in President Donald Trump’s Working Families Tax Cut Act, the legislation which also restored the FCC’s auction authority.

Anthropic expanded the reach of its Mythos AI model to an additional 150 companies across 15 countries but stated each will need to meet its security requirements before they gain access.

Anthropic introduced its Claude Mythos model on 7 April, under the auspices of its Project Glasswing to a limited number of technology companies including Amazon Web Services, Apple, T-Mobile US, AT&T, Nvidia and Google, instead of making it publicly available.

The company stated the new cohort features industries which were underrepresented in the first batch. It now includes power grids, water systems, healthcare networks, communications providers, and hardware manufacturers.

Anthropic stated for most of the Project Glasswing partners, a successful cyberattack on their codebases could affect more than 100 million people.

It also noted many of the new partners are vendors, companies or nonprofits that maintain codebases which are relied upon by numerous organisations around the world, including governments.

The company expects within six-to-12 months, many other AI developers will have models comparable to Mythos Preview and stated, “they could release them without safeguards that prevent misuse”.

Results from the first cohort are already in. Project Glasswing partners have collectively surfaced more than 10,000 high-or critical-severity security vulnerabilities in the first few weeks.

The AI player stated the bottleneck in cybersecurity is now verifying, disclosing, and patching the large numbers of vulnerabilities which Mythos-class models can surface.

It noted many of Project Glasswing’s partners now use the model to write patches, as well as for pre-release checks which prevent vulnerabilities from appearing in the first place.

The expansion came a day after the Anthropic stated it will start offering Mythos access to the European Union’s cybersecurity division.

It also confidentially filed its initial public offering prospectus with the US Securities and Exchange Commission ahead of rival OpenAI.

EchoStar elected to defer approximately $183 million in cash interest payments due on debt held by its Dish DBS Corporation subsidiary, citing a preference to conserve liquidity while it awaits the closing of its spectrum deal with AT&T.

According to a statement, the missed payments span three tranches of Dish DBS notes: around $72.2 million on 5.25% secured notes due 2026, $71.9 million on 5.75% secured notes due 2028 and $38.4 million on 5.125% unsecured notes due 2029.

The company stated it skipped the payments deliberately to preserve cash while it waits for the AT&T deal to close, implying it does not intend to make the payments within the grace period.

The notes were part of the broader debt load accumulated by Dish Network over years of spectrum acquisitions and satellite operations, debt which became central to EchoStar’s financial stress and its motivation to complete the $23 billion AT&T deal.

Under the terms of the relevant indentures, the non-payment is classed as a default, though EchoStar has a 30-day grace period before it formally constitutes an event of default.

EchoStar said both the Federal Communications Commission (FCC) and the US Department of Justice granted regulatory approval for the AT&T transaction, though the FCC’s sign-off is not yet final. The company noted the closing remains subject to the satisfaction or waiver of additional conditions.

The deal, announced in August 2025, will generate net proceeds of $20.25 billion according to EchoStar’s filing, reflecting adjustments and transaction costs applied to the gross figure.

AI player Anthropic confidentially submitted paperwork for its proposed initial public listing ahead of rival OpenAI, while also giving the European Union’s cybersecurity body preliminary access to its Mythos AI tool.

The draft registration statement submitted to the US Securities and Exchange Commission gives the company the option to go public after the agency completes its review.

Anthropic stated the number of shares to be offered and the price have not yet been set.

News of the IPO move came the same day (1 June) Bloomberg reported Anthropic will give ENISA, the European Union’s cybersecurity agency, access to Mythos through Project Glasswing, an initiative which allows organisations to test Mythos’ capabilities before a wider release.

There are growing concerns among governments over the security implications of Mythos, which Anthropic released to some private companies in April.

Anthropic communicated the decision to the European Commission over the weekend.

EC spokesperson Thomas Regnier confirmed the development to Mobile World Live (MWL) followed several weeks of productive discussions.

 “We welcome the latest developments on potential future access,” he said. “This is the result of the Commission’s strong bilateral cooperation and engagement with Anthropic, a leading frontier AI company.”

The EC was careful to frame the moment not as a resolution but as a starting point to work with the US administration, Anthropic and additional AI companies such as OpenAI.

“This is a shared challenge, and we are intensifying our discussions with like-minded partners, including the United States,” Regnier said.

The plan is for ENISA to join Project Glasswing, the coalition Anthropic announced in April which includes Amazon, Apple, AT&T, T-Mobile US, Microsoft, Google, CrowdStrike, Nvidia and Palo Alto Networks, among others.

Meta Platforms reportedly acknowledged its controversial employee surveillance programme captures data from employees outside the US, raising fresh legal questions in Europe.

Reuters reported internal documentation it reviewed showed the company’s Model Capability Initiative (MCI) does capture data outside of the US.

MCI was introduced last month as a tool to record how US-based employees interact with their work computers by tracking mouse movements, clicks and navigation patterns across more than 200 apps and websites.

The goal of MCI is to use the employee-generated data to train AI agents capable of performing coding and white-collar tasks.

Meta told staff the programme is confined to US devices and stated safeguards are in place to protect sensitive information.

The news agency noted Meta acknowledged in a question-and-answer document provided to employees MCI will capture the contents of any emails or direct messages sent to US personnel, regardless of the sender’s ⁠location.

Meta spokesperson Dave Arnold told Reuters the company notified non-US employees the tool was running on the machines of US-based colleagues they might correspond with, describing the step as one of transparency.

A representative for Meta told Mobile World Live: “We’ve been clear that this tool is for US-based personnel only, and in the interest of transparency, we notified non-US employees that it was deployed on the computers of US colleagues they may email or chat with in the normal course of business.”

“We carefully considered and mitigated potential privacy risks in both the development and deployment of this tool, and we are committed to complying with applicable laws and regulations.” 

New regulatory exposure
Reuters stated the disclosure introduces new regulatory exposure in Europe, where technology companies are already fighting a series of heated legal battles over data collection.

Under the EU’s GDPR rules, the news site explained companies must establish a clear legal basis for processing personal data, disclose what is being collected and satisfy strict conditions around sensitive categories of information.

Kleanthi Sardeli, a legal expert at privacy advocacy group NOYB, told the news site even limited or incidental capture of EU employee data could put Meta in breach of GDPR rules.

A key question, she said, is whether data originally gathered for work communications can lawfully be repurposed to train an AI model.

The European Union (EU) is pressing for deeper talks with the US administration over advanced AI models, and at the heart of the conversation is Anthropic’s Mythos.

There are growing concerns among governments over the security implications of Mythos, which Anthropic released to private companies in April.

Its release triggered an immediate wave of concern when it surfaced the model could identify tens of thousands of software vulnerabilities at a scale no previous system had demonstrated.

The AI player introduced its Mythos model on 7 April, under the auspices of Project Glasswing, to a limited number of technology companies including Amazon Web Services, Apple, Nvidia and Google.

Anthropic expects to bring Mythos-class models to all customers in the coming weeks.

Bloomberg previously reported the EU made limited progress in securing access to details of vulnerabilities Anthropic’s Mythos AI model could reveal.

European Commission spokesperson Thomas Regnier told Mobile World Live (MWL) the agency has had several meetings with Anthropic to understand the capability of the model, its implications for the cybersecurity of the EU and Anthropic’s plan around Project Glasswing.

“We will keep discussing with the company the cyber capabilities and risks of its latest model,” he stated.

CNBC reported Anthropic has yet to grant the EU, its AI office or any government organisations outside of the US, aside from the UK’s AI Security Institute, preview access to Mythos.

Since August 2025, the European Commission’s AI Office has held regular technical meetings with Anthropic tied to the General-Purpose AI Code of Practice, to which the company is a signatory.

A spokesperson for the EC noted Mythos is not a one-off as a “new wave of powerful models are coming to the market”.

The EC stated parallel progress is being made towards releasing OpenAI’s GPT-5.5-Cyber to trusted EU entities.

The EC spokesperson told MWL it is intensifying discussions with the US, “particularly on the most advanced AI models, including those with cyber capabilities”.

“Cybersecurity is a shared priority and we have agreed to mutually recognise our respective standards in this area,” the spokesperson stated.  “On EU side, we are also stepping up our cyber defences through targeted investments in AI and supercomputing.”

The US Space Force (USSF) granted SpaceX a $4.1 billion contract to build a constellation of birds capable of detecting and tracking airborne threats globally, which signals a shift in how the military conducts battlefield surveillance.

The competitive Other Transaction Authority agreement, announced last week (29 May) by Space Systems Command, covers the space-based airborne moving target indicator (SB-AMTI) programme.

SB-AMTI architecture integrates advanced space-based sensors, secure and rapid communication links, and resilient ground processing.

The deal tasks SpaceX with fielding an initial satellite constellation by 2028, giving joint military personnel an early capability to close what officials describe as dangerous operational blind spots.

The driving force behind the programme is a growing recognition traditional airborne platforms for tracking moving targets are increasingly vulnerable. As adversaries field more sophisticated anti-access and area-denial systems, the Pentagon has concluded a persistent, space-based sensing layer is essential.

USSF acting portfolio acquisition executive for space-based sensing and targeting Colonel Ryan Frazier, said the shift to space gives joint warfighters continuous awareness of contested airspace in a way ground or airborne systems cannot match.

He noted development and integration work is beginning immediately to meet the programme’s accelerated timeline and address pressing national security demands.

USSF has assembled a multi-vendor pool which includes numerous companies selected through the Space Systems Command’s other transaction authority agreements announced at the Space Symposium in April.

The SB-AMTI award landed several days after the USSF confirmed a separate $2.29 billion contract with SpaceX to build the Space Data Network Backbone.

A Blue Origin New Glenn rocket exploded during a test, a potential blow to AST SpaceMobile and its launch schedule.

The New Glenn explosion yesterday (28 May) at Cape Canaveral in the US state of Florida will likely lead to lengthy investigations by the US Federal Aviation Administration (FAA) and NASA, which will sideline future launches.

In late 2024, AST SpaceMobile signed a multi-launch agreement with Jeff Bezos’ Blue Origin. It previously relied on SpaceX’s Falcon 9 rockets to launch its birds into orbit before attempting to branch out to the larger New Glenn models.

AST SpaceMobile has predicted an orbital launch cadence of roughly every one to two months this year through deals with multiple launch providers as it continues to target having approximately 45 birds in orbit by the end of 2026.

New Glenn’s seven meter-wide payload fairing is one of the few in the industry capable of accommodating the 2,400 square-foot phased arrays of AST SpaceMobile’s Block 2 BlueBird satellites, with the potential to carry up to eight per flight.

Fallout
“The New Glenn failure is a tough blow to AST which, due to the size of its satellites, has limited options for launch and New Glenn was by far the best option,” Chris Quilty, founder and CEO of research company Quilty Space told Mobile World Live (MWL), adding the company would now struggle to achieve its launch target for the year.

Tim Farrar, president at consulting company TMF Associates, told MWL the explosion has a “huge impact since this was the primary launch vehicle and it will take a year or more to rebuild the [launch] pad”.

“I think this pushes [AST’s] continuous commercial service back to 2028,” he added.

A representative for AST SpaceMobile stated the company’s near-term launches are unaffected.

“None of the missions planned for the next few months are scheduled with Blue Origin. Our satellites are designed to be launcher-agnostic, and we have agreements in place with multiple launch providers, giving us flexibility across our launch programme.”

BlueBirds 8, 9, and 10 are already at Cape Canaveral undergoing final processing ahead of a planned launch on a SpaceX Falcon 9 rocket next month.

A launch of AST SpaceMobile’s next-generation BlueBird 7 satellite from a Blue Origin New Glenn rocket last month fell short of the required orbit, resulting in its loss.

Broadcom and Samsung Electronics launched what they claim is the first integrated 5G and Wi-Fi 8 fixed wireless access (FWA) platform, a milestone for the home broadband industry.

The platform uses Broadcom’s BCM6776 Wi-Fi 8 SoC and Samsung’s B1320 5G modem in a reference design for mass-market equipment which is compatible with 3GPP Release-17 and the emerging Wi-Fi 8 IEEE 802.11bn standard. 

It is also compatible with new radio and narrowband NTN bands, giving operators a degree of connectivity resilience which the companies noted was previously out of reach for consumer-grade hardware.

Samsung’s B1320 is a 5nm chipset capable of delivering 5G data rates of 3.4Gb/s in the downlink and 1.2Gb/s up.

Broadcom’s BCM6776 is a tri-band, single-chip product covering 2.4GHz, 5GHz and 6GHz simultaneously, with a quad-core Arm network processor and integrated multi-gigabit physical layer.

The design cuts active power consumption by 50% compared with Broadcom’s previous generation.

Broadcom asserted the combination of the 5G modem and Wi-Fi 8 radio into a tightly integrated reference platform can lower OEMs’ bill-of-materials and simplify board design.

It stated Humax Networks and WNC are already producing next-generation gateways using the platform and global operator trials are underway.

Joonsuk Kim, EVP and head of CP development at Samsung Electronics, framed the platform around accessibility, describing it as a tool provide high-quality connectivity “across a wide range of environments”.

Vijay Nagarajan, VP of Broadcom’s marketing, wireless and broadband communications division, pointed to the coordinated performance between 5G and Wi-Fi 8 as a differentiator for operators trying to guarantee consistent coverage in “every corner of the home”.

American Airlines detailed a plan to install Starlink satellite internet service across more than 500 narrowbody aircraft starting in early 2027.

The deal will cover much of its Airbus domestic and short-haul international aeroplanes including A321neo and A321XLR aircraft entering the fleet.

Starlink’s Aero Terminal delivers up to 1Gb/s per antenna, enabling streaming, gaming and real-time collaboration tools for passengers.

American Airlines chief customer officer Heather Garboden said the partnership is as much about reliability and low latency as raw speed, promising passengers an at-home level of Wi-Fi connectivity.

Jason Fritch, VP of Starlink enterprise sales at SpaceX, said the service would deliver a fully connected experience for passengers and crew, “making every flight smoother and more enjoyable”.

The partnership arrives as Starlink rival Amazon LEO is building its own airline momentum. JetBlue became the first carrier to commit to the service in September 2025, with a rollout planned to start in 2027.

Earlier this year, Delta Air Lines followed with a multi-year agreement to equip 500 aircraft with Amazon Leo starting in 2028

A report by Telus Digital exposed significant security vulnerabilities across the generative AI landscape, which included finding every major model could be coaxed into unsafe behaviour under the right conditions.

In the company’s second GenAI Safety Model Benchmark, Telus Digital’s testing found some models engaged with harmful requests more than 90% of the time and stated most enterprises are dangerously underprepared to defend against them.

The testing drew on more than 620,000 adversarial tests across 34 AI models from 10 global providers: Anthropic, OpenAI, Google, Meta, Alibaba, Baidu, ByteDance, Zhipu AI, 01.AI and Mistral.

It is the most extensive AI security study Telus Digital has conducted to date, nearly doubling the scope of the first edition published in November 2025.

Attack vulnerability rates across tested models ranged from 1.3% to 93%, where a lower percentage means a safer model. 

Anthropic’s Claude models claimed five of the 10 lowest vulnerability scores, including the benchmark’s overall lowest rate, but Telus Digital noted even single-digit failure rates are unacceptable in high-stakes enterprise contexts involving money, health and reputation.

The research identified model size, reasoning capability and the creator’s overall safety approach as the strongest predictors of resilience.

Reasoning models, designed to deliberate before responding, proved significantly harder to exploit, with a 19.9% vulnerability rate compared to 55.1% for standard models which skip the reasoning step.

Smaller models are consistently the most susceptible to attacks, regardless of whether they are open-source or proprietary. The study found open source models are not inherently less safe than closed ones, with GLM 4.7 from China’s Zhipu AI outperforming many proprietary alternatives.

The benchmark also highlighted where risks cluster most sharply: privacy exploitation, fraud and cybersecurity threats remain the hardest categories for even leading models to handle.

Telus Digital also flagged a pattern called “refuse-but-engage,” where a model declines a harmful request but still provides related information which could cause harm or reputational damage.

Global AI spending is projected to reach $2.52 trillion in 2026, yet spending on AI trust, risk, and security management is projected to be just $3.4 billion, which is roughly $1 in security for every $735 spent on AI capabilities.

Meanwhile, 86% of organisations report having already experienced an AI-related security incident.

Telus Digital urges enterprises to move beyond one-time or periodic safety checks toward continuous, automated adversarial testing embedded directly into development workflows, layered with human oversight and clean data practices.
