LiteLLM, an open source gateway which translates API calls for over 100 large language models into a single OpenAI-compatible format, was not directly compromised in the attack, as hackers targeted a known vulnerability in Aqua Security's Trivy. The list included many large and critical service providers, including but not limited to Cisco, Samsung, Salesforce, and Amazon Web Services, as well as Airbus U.S. Space & Defense, Thales Group, Deutsche Bahn, Munich Re, and the London Stock Exchange Group. Latest Videos FromTechRadar An attack that is still a concern nearly five months later. The original attack occurred on March 24 2026 and was spearheaded by a financially motivated hacking group called TeamPCP, which compromised Trivy, an open source security tool that scans for vulnerabilities. The modified package, which was subsequently downloaded and 'invited' in by LiteLLM without checking its ID- an automated process that essentially allowed a poisoned version of the trusted tool in- gained server administrator privileges and then installed a stealer. The stealer compromised credentials and secrets far more valuable than corporate data, including Cloud keys, SSH keys, Kubernetes tokens, environment variables, repository and package-publishing tokens, and AI provider keys. These are arguably worse from a security standpoint than a singular breach because of both the scale of the attack and the fact that hackers now had a 'key' to many security doors rather than having to run exploits to get there. The victim-scale research done by CloudSEK was further corroborated the following day by Hudson Rock, and it painted a grim picture of what was still an outstanding issue nearly 5 months after the original attack. The irony is that some of the credentials still work: Independent researcher Kevin Beaumont said some of the compromised keys were still valid after he tested them, even as the impacted organization insisted it had 'rotated' those keys to new ones. CloudSEK's figures indicate 2,500-plus companies and 434,000 CI/CD pipelines were compromised, while Hudson Rock has released a 153 GB archive of the exfiltrated material after examining a 195 TB file it had obtained. Both firms are running domain-lookup tools so organizations can check their own exposure online. Whether these revelations lead organizations to double-check their use of AI tools in multiple mission-critical instances that could compromise not only customer data but their own trade secrets down the line remains to be seen.

RelyComply integrates LSEG World-Check On Demand to deliver real-time financial crime risk management. 19th August 2026 Font size: - + RelyComply has announced a partnership with LSEG Risk Intelligence to integrate World-Check On Demand into its financial crime compliance platform, helping global financial institutions strengthen screening, due diligence and ongoing monitoring workflows. World-Check On Demand delivers structured, machine-readable risk intelligence through an API-first architecture, enabling organisations to access sanctions, politically exposed persons, adverse media and enforcement information in real time as part of customer onboarding, screening and ongoing monitoring processes. As regulatory expectations continue to rise, many compliance teams face a growing challenge: managing the increasing volume of alerts, investigations, and reporting requirements without significantly expanding resources. False positives remain one of the biggest operational burdens in AML programmes, consuming valuable time and resources that could be directed towards genuine financial crime risks. At the same time, financial institutions are under pressure to streamline customer onboarding and due diligence processes while maintaining strong controls against financial crime, sanctions breaches and fraud. Through the partnership, RelyComply integrates LSEG World-Check On Demand into a single AI-driven platform that supports customer screening, identity verification, enhanced due diligence and ongoing monitoring. The integration is designed to support more efficient screening and investigation workflows by bringing together relevant risk intelligence within existing compliance processes, while leaving institutions responsible for their own risk assessment and decision-making. "For years, organisations focused on gaining access to more data. Today, the challenge is turning that data into measurable outcomes. Regulators increasingly want evidence that compliance programmes and technology solutions are effective, not simply that they exist," says Brad Elliott, CEO of RelyComply "That expectation extends beyond AML monitoring. Organisations must also demonstrate effective onboarding, due diligence and ongoing risk management. By combining explainable AI-driven capabilities and automation, we help compliance teams manage compliance requirements more efficiently and at scale." "Our partnership with LSEG Risk Intelligence helps organisations streamline compliance processes while strengthening their ability to manage financial crime risk with confidence." The announcement comes at a time when financial institutions in South Africa, the United Kingdom and other regulated markets are under increasing pressure to strengthen financial crime controls, demonstrate effective compliance with the Financial Action Task Force (FATF) recommendations, and meet evolving AML, counter-terrorist financing and Know Your Customer requirements. Priya Nallan, Head of Product, Screening, at LSEG Risk Intelligence, comments: "Financial crime compliance is increasingly shaped by the ability to access and operationalise trusted intelligence in real time. World-Check On Demand was designed to help organisations embed this directly into their workflows. "Through the partnership with RelyComply, we are helping compliance teams access timely, structured intelligence within the processes they already use, supporting more efficient screening, due diligence and ongoing monitoring." As compliance becomes increasingly data-rich, industry focus is shifting from access to intelligence towards the ability to operationalise it. For many organisations, the next phase of compliance transformation will be defined not by how much data they have, but by how effectively they can use it.

Under Armour sees A bigger sales slide in North America. The sportswear maker now expects a mid-single-digit revenue decline, even as it sticks with its profit forecast and pushes a slimmer, higher-priced lineup. about 1 hour ago - 2 mins What's going on here? Under Armour just penciled in a bigger sales drop for the year after North America revenue fell 9% last quarter, and the stock slipped in premarket trading. What does this mean? Under Armour, a sportswear maker, is facing a tougher US consumer backdrop: higher everyday costs have left shoppers pickier about new shoes and apparel. In the quarter ended June 30th, North America revenue fell 9% to $609.8 million and total revenue dipped 3% to $1.10 billion, slightly below what analysts expected, according to LSEG data cited by Reuters. Even so, profit beat estimates, and the company kept its full-year operating income forecast. That gap between weaker sales and... Keep reading for free.

NatWest bets on LSEG veteran Triona O'Keeffe to lead its AI data push. NatWest Group has named former Deutsche Bank and LSEG executive Triona O'Keeffe as its new Chief Data and Analytics Officer, effective January 2027. NatWest Group has moved decisively to reinforce its technology leadership, appointing Triona O'Keeffe as Chief Data and Analytics Officer in a hire that signals the bank's growing conviction that data infrastructure and artificial intelligence are now central to competitive banking. O'Keeffe, who joins from the London Stock Exchange Group (LSEG) and previously held a senior role at Deutsche Bank, will take up her position in January 2027, reporting directly to Group Chief Information Officer Scott Marcar. A strategic hire at a critical inflection point. The appointment is more than a routine executive reshuffle. NatWest has framed the move explicitly around a strategic objective: drawing its data, artificial intelligence, and engineering capabilities into a more tightly integrated operating model. The ambition is to accelerate the delivery of digital products and features to customers - a goal that has become a defining competitive battleground for incumbent banks facing persistent pressure from digital-native challengers and fintech disruptors across the United Kingdom and Europe. O'Keeffe's background makes her an unusually well-calibrated choice for this mandate. Her tenure at LSEG exposed her to one of the most data-intensive environments in global financial services, where the management of vast, real-time market data streams, analytics infrastructure, and technology integration - most visibly through LSEG's landmark acquisition of Refinitiv - demands precisely the kind of cross-functional data leadership NatWest is now seeking to replicate internally. Before that, her work at Deutsche Bank would have immersed her in the complexity of data governance, regulatory reporting requirements, and enterprise-scale engineering challenges that characterise large, globally systemic institutions. The logic of convergence. NatWest's decision to unify data, AI, and engineering under a single remit reflects a broader architectural shift occurring across major financial institutions. For years, many large banks maintained siloed structures in which data management, technology engineering, and advanced analytics operated as distinct - and often poorly coordinated - functions. The cost of that fragmentation has become increasingly visible: slower product development cycles, duplicated infrastructure investment, and an inability to translate data assets into personalised customer experiences at speed and scale. By creating a consolidated Chief Data and Analytics Officer role with apparent proximity to the engineering function, NatWest is signalling that it intends to close that gap. The reporting line to Scott Marcar, the Group Chief Information Officer, is itself instructive. Placing the data and analytics function within the technology leadership chain - rather than, say, under the Chief Financial Officer or a standalone digital division - reflects a conviction that data strategy must be operationally embedded rather than organisationally peripheral. AI as the Underlying Driver. The explicit reference to artificial intelligence in the framing of O'Keeffe's appointment deserves particular attention. NatWest, like most major retail and commercial banks, has been investing in AI applications spanning fraud detection, credit decisioning, customer service automation, and personalised financial guidance. The challenge facing institutions of NatWest's scale is rarely a shortage of AI ambition - it is the foundational data quality, governance, and pipeline architecture required to translate that ambition into production-ready, regulatorily compliant AI deployments. A Chief Data and Analytics Officer with deep capital markets data experience, arriving at a moment when regulators across the United Kingdom and the European Union are intensifying scrutiny of algorithmic decision-making in financial services, will need to balance two imperatives simultaneously: accelerating AI adoption and ensuring the data foundations underpinning those systems are robust, auditable, and fair. O'Keeffe's dual background - at a market infrastructure giant and a globally systemic investment bank - suggests an executive who has navigated precisely this tension before. What this means for NatWest's digital trajectory. O'Keeffe's January 2027 start date gives NatWest time to onboard a senior leader deliberately rather than urgently, suggesting the appointment reflects forward planning rather than a response to a capability crisis. For a bank that has been steadily investing in its digital banking proposition - including through its digital retail brand and broader technology modernisation programmes - the hire represents a considered bet that the next phase of competitive differentiation will be won or lost in the quality of data and AI infrastructure rather than in product design alone. For observers of the UK banking sector, the appointment reinforces a pattern visible across large incumbents: the elevation of data leadership to the highest tiers of organisational authority, on a par with traditional finance, risk, and compliance functions. The question now is whether O'Keeffe can translate her cross-industry data expertise into measurable acceleration of NatWest's digital product pipeline - and whether the structural integration of data, AI, and engineering delivers the compounding returns the bank is clearly anticipating.
