Prompt injection is exploiting enterprise AI's biggest design flaws by targeting agents, RAG pipelines and model routers

In the past two years, businesses have been trying to fit large language models (LLMs) into support, analytics, development, and internal automation like never before. Along with the increasing adoption of AI technology, another trend is gaining momentum — cybercriminals are taking advantage of the disconnect between assumptions about LLMs and their actual characteristics. In 2025 and 2026, several independent sources have highlighted the same trend: Prompt injection remains one of the most impactful and widely demonstrated attack vectors against LLM systems. The OWASP LLM Top 10 (2025) lists prompt injection as LLM01, identifying it as the most critical category of LLM‑specific vulnerabilities, for the second consecutive edition. OWASP's ranking reflects the fact that LLMs still struggle to reliably separate instructions from data, making them susceptible to manipulation through crafted inputs. CrowdStrike's 2026 Global Threat Report — built on frontline intelligence across more than 280 tracked adversaries — documented that threat actors injected malicious prompts into legitimate generative AI tools at more than 90 organizations in 2025. They then used those injections to generate commands that stole credentials and cryptocurrency. The report stated it plainly: "Prompts are the new malware." AI-enabled adversaries increased their overall attack volume by 89% year-over-year, with prompt injection working as both an entry point and a force multiplier. Real‑world incidents illustrate the operational impact. In August 2024, researchers at PromptArmor disclosed a prompt injection vulnerability in Slack AI that allowed an attacker to exfiltrate data from private Slack channels they had no access to — including API keys shared in private developer channels — by placing a malicious instruction in a public channel or embedding it in an uploaded document. In June 2025, resear... Source: https://venturebeat.com/security/prompt-injection-is-exploiting-enterprise-ais-biggest-design-flaws-by-targeting-agents-rag-pipelines-and-model-routers

Madonna Says Using AI Is the ‘Opposite of Making Art’

Madonna recently slammed artificial intelligence in a new interview with Vogue Italia, telling the outlet that relying on AI is the “opposite of making art.” “Once you were around painters and musicians and dancers and artists in one place and working from a very pure place for each other. I value that experience a lot,” […] Source: https://variety.com/2026/music/news/madonna-ai-opposite-of-making-art-1236797851/

When the rapid adaptation of sales channels pays off

Greater agility in the sales system—that is, a company's ability to rapidly adapt its sales channels to changing market conditions—is associated with higher operating profit, but only under certain conditions. That is the result of an observational, survey-based study involving 356 predominantly European companies carried out by retail and marketing experts from the University of Cologne, the École des hautes études commerciales Paris (HEC Paris), the University of Mannheim and the University of Manchester.

Heat waves mess with your brain. Scientists are trying to figure out why.

It’s been hot in London this week. Really hot. A dangerous heat wave has hit Western Europe. Yesterday, the UK recorded its highest ever June temperature at 36.1 °C (about 97 °F). But as the weather app on my phone confirmed, it felt like 39 °C. It’s frightening that we are seeing such temperatures in… Source: https://www.technologyreview.com/2026/06/26/1139760/heat-waves-mess-with-your-brain-scientists-are-trying-to-figure-out-why/
