Ransomware has evolved – so must our defences

Traditional defences typically monitor north-south traffic (from inside to outside the network), missing the lateral movement that characterises today’s threats. By monitoring internal traffic flows, privileged account behaviour and unusual data transfers, organisations gain the ability to identify suspicious actions in real time and contain threats before they escalate to ransomware deployment or public extortion. The ransomware attack on NASCAR illustrates this breakdown. Attackers from the Medusa ransomware group infiltrated the network using stolen credentials and quietly exfiltrated sensitive user data before launching a broader extortion campaign. Because these internal activities weren’t spotted early, the attack matured to a point of public disclosure, operational disruption and reputational harm. ... The emergence of triple extortion and the increasing sophistication of threat actors indicate that ransomware has entered a new phase. It is no longer solely about file encryption; it is about leveraging every available vector to apply maximum pressure on victims. Organisations must respond accordingly. Relying exclusively on prevention is no longer viable. Detection and response must be prioritised equally. This demands a strategic investment in technologies that provide real-time visibility, contextual insight and adaptive response capabilities.


Proof-of-Concept in 15 Minutes? AI Turbocharges Exploitation

The project, which the researchers dubbed Auto Exploit, is not the first to use LLMs for automated vulnerability research and exploit development. NVIDIA, for example, created Agent Morpheus, a generative AI application that scans for vulnerabilities and create tickets for software developers to fix the issues. Google uses an LLM dubbed Big Sleep to find software flaws in open source projects and suggest fixes. ... The Auto Exploit program shows that the ongoing development of LLM-powered software analysis and exploit generation will lead to the regular creation of proof-of-concept code in hours, not months, weeks, or even days. The median time-to-exploitation of a vulnerability in 2024 was 192 days, according to data from VulnCheck. ... Overall, the fast pace of research and quick adoption of AI tools by threat actors means that defenders do not have much time, says Khayet. In 2024, nearly 40,000 vulnerabilities were reported, but only 768 — or less than 0.2% — were exploited. If AI-augmented exploitation becomes a reality, and vulnerabilities are not only exploited faster but more widely, defenders will truly be in trouble. "We believe that exploits at machine speed demand defense at machine speed," he says. "You have to be able to create some sort of a defense as early as 10 minutes after the CVE is released, and you have to expedite, as much as you can, the fixing of the actual library or the application."


How being "culturally fit" is essential for effective hiring

The evaluation process doesn't end at hiring—it continues throughout the probation period, making it a crucial phase for assessing cultural alignment. Effectively utilising this time helps identify potential cultural mismatches early on, allowing for timely course correction. Tools like scorecards, predefined benchmarks, and culturally responsive assessment tests help minimise bias while ensuring a fair evaluation. ... First, leadership accountability must be strengthened by aligning cultural beliefs into KPIs and performance reviews, ensuring managers are assessed on their ability to model and enforce them. With this, equipping leaders with the necessary training and situational guidance can further reinforce these standards in daily interactions. Additionally, blending recognition and rewards with culture—through incentives, peer recognition programmes, and public appreciation—encourages employees to embody the company's ethos. Open communication channels like pulse surveys, town halls, and anonymous reporting help organisations address concerns effectively. Most importantly, leaders must lead by example, actively participating in cultural initiatives and making transparent decisions reinforcing company ideals. This will strengthen cultural alignment, leading to higher employee satisfaction and greater organisational success.


AI drives content surge but human creativity sets brands apart

The report underlines that skilled human input is still regarded as critical to content quality and audience trust. Survey results illustrate consumer reluctance to embrace content that is fully AI-generated: over 70% of readers, 60% of music listeners, and nearly 60% of video viewers in the US are less likely to engage with content if it is known to be produced entirely by AI. Bain suggests that media companies could use the "human created" label as a point of differentiation in the crowded market, in a manner similar to how "fair trade" has been used for consumer goods. Established franchises and intellectual property (IP) are viewed as important assets, with Bain noting that familiarity and trust in brands continue to guide audience choices, both in music and visual media. ... The report also reviews how monetisation models are being affected by these changes. While core methods, such as subscription tiers and digital advertising, remain largely stable, there is emerging potential in areas like hyper-personalisation and fan engagement - using data and AI to deliver exclusive content or branded experiences. Integrations across media and retail sectors, shoppable content, and more immersive ad formats are also identified as growth opportunities. ... Bain concludes that although the "flooded era" of AI-assisted content poses operational and strategic challenges, creative differentiation will be significant for success.


The CISO succession crisis: why companies have no plan and how to change that

Taking on the cybersecurity leader role is not just about individual skills, the way many companies are structured keeps mid-level security leaders from getting the experience they’d need to move into a CISO role. Myers points to several systemic problems that make effective succession planning tough. “For a lot of cases, the CISO role for the top job is still pretty varied within the organization, whether they’re reporting to the CIO, the CFO, or the CEO,” she explains. “That limits the strategic visibility and influence, which means that the number two doesn’t really get the executive exposure or board-level engagement needed to really step into that role.” The issue gets worse because of the way companies are set up, according to Myers. CISOs often oversee a wide range of responsibilities, risk, compliance, governance, vendors, data privacy and crisis management. But cyber teams are usually lean and split into narrow functions, so most deputies only see a piece of the picture. ... Board experience presents another significant barrier. “The CISO has to have board experience, especially depending on the industry or the type of company and their ownership structure. That’s pretty critical,” Myers says. “That’s a hard thing to just walk into on day one and have that credibility and trust without having had the opportunity to develop it throughout your tenure.”


Forget data labeling: Tencent’s R-Zero shows how LLMs can train themselves

The idea behind self-evolving LLMs is to create AI systems that can autonomously generate, refine, and learn from their own experiences. This offers a scalable path toward more intelligent and capable AI. However, a major challenge is that training these models requires large volumes of high-quality tasks and labels, which act as supervision signals for the AI to learn from. Relying on human annotators to create this data is not only costly and slow but also creates a fundamental bottleneck. It effectively limits an AI’s potential capabilities to what humans can teach it. To address this, researchers have developed label-free methods that derive reward signals directly from a model’s own outputs, for example, by measuring its confidence in an answer. While these methods eliminate the need for explicit labels, they still rely on a pre-existing set of tasks, thereby limiting their applicability in truly self-evolving scenarios. ... “What we found in a practical setting is that the biggest challenge is not generating the answers… but rather generating high-quality, novel, and progressively more difficult questions,” Huang said. “We believe that good teachers are far rarer than good students. The co-evolutionary dynamic automates the creation of this ‘teacher,’ ensuring a steady and dynamic curriculum that pushes the Solver’s capabilities far beyond what a static, pre-existing dataset could achieve.”


There's a Stunning Financial Problem With AI Data Centers

Underlying the broader, often poorly-defined AI tech are data centers, which are vast warehouses stuffed to the brim with specialized chips that transform energy into computational power, thus making all your Grok fact checks possible. The economics of data centers are fuzzy at best, as the ludicrous amount of money spent building them makes it difficult to get a full picture. In less than two years, for example, Texas revised its fiscal year 2025 cost projection on private data center projects from $130 million to $1 billion. ... In other words, new data centers have a very tiny runway in which to achieve profits that currently remain way out of reach. By Kupperman's projections, a brand new data center will quickly become a Theseus' ship made up of some of the most expensive technology money can buy. If a new data center doesn't start raking in mountains of cash ASAP, the cost to maintain its aging parts will rapidly overtake the revenue it can bring in. Given the current rate at which tech companies are spending money without much return — a long-term bet that AI will all but make human labor obsolete — Kupperman estimates that revenue would have to increase ten-fold just to break even. Anything's possible, of course, but it doesn't seem like a hot bet. "I don’t see how there can ever be any return on investment given the current math," he wrote.


Employee retention: 7 strategies for retaining top talent

Smith doesn’t wait for high performers on his IT team to seek out challenges or promotions; rather, department leaders reach out to discuss what the company can offer to keep them engaged, interested, and fulfilled at work. That may mean quickly promoting them to positions or offering them new work with a more senior title, Smith says, explaining that “if we don’t give them more interesting work, they’ll find it elsewhere.” ... Ewles endorses that kind of proactive engagement. She also advises organizations to conduct stay interviews to learn what keeps workers at the organization, and she recommends doing flight risk assessments to identify which workers are likely to leave and how to make them want to stay. “Those can be key differentiators in retaining top talent,” she adds. ... CIOs who want to retain them need to give them more opportunities where they are, she adds. ... Similarly, Anthony Caiafa, who as CTO of SS&C Technologies also has CIO responsibilities, directs interesting work to the high performers on his IT team, saying that they’re “easier to keep if you’re providing them with complex problems to solve.” That, he notes, is in addition to good compensation, mentoring, training, and advancement opportunities. ... Knowing they’re contributing something of value is part of a good retention policy, says Sibyl McCarley, chief people officer at tech company Hirevue.


Challenging Corporate Cultures That Limit Strategic Innovation

A thriving innovation culture requires that companies shift away from rigid, top-down hierarchies in favor of more flexible structures with accessible leaders where communication flows freely up and down the chain of command and across functional groups. Such changes make innovation a more accessible process for employees, prevent communication breakdowns, and streamline decision-making. ... All successful companies enjoy explosive periods of growth as represented by the steep part of the S-curve. When that growth starts to level off, the company is enjoying much success and generating much cash. It is at this point that management teams get comfortable, enjoying the momentum of their success. This is precisely when they should start to become uncomfortable and alert to new innovation possibilities. ... There is a natural tendency to avoid risk, but risk is an essential component of strategic innovation. The key is attacking that risk through the use of intelligent failure—failure that happens with a purpose and provides the insights needed for success. When implementing a major innovation initiative, intelligent failure is an essential part of systematically reducing the most critical risks—the risks that can cause the entire initiative to fail. Success comes from attacking the biggest risks first, addressing fundamental uncertainties early, and taking bite-sized risks through incremental proof-of-concept steps.


Building Real Enterprise AI Agents With Apache Flink

The common approach today is to stitch together a patchwork of disconnected systems: one for data streaming (like Apache Kafka), another for workflow orchestration, one for aggregating all the possible contextual data the agent might need and a separate application runtime for the agent’s logic. This “stitching” approach creates a system that is both operationally complex and technically fragile. Engineers are left managing a brittle architecture where data is handed off between systems, introducing significant latency at each step. This process often relies on polling or micro-batching, meaning the agent is always acting on slightly stale data. ... While Flink provides the perfect engine, the community recognized the need for better native support for agent-specific workflows. This led to Streaming Agents, designed to make Flink the definitive platform for building agents. Crucially, this is not another tool to stitch into your stack. It’s a native framework that directly extends Flink’s own DataStream and Table APIs, making agent development a first-class citizen within the Flink ecosystem. This native approach unlocks the most powerful benefit: the seamless integration of data processing and AI. Before, an engineer might have one Flink job to enrich data, which then writes to a message queue for a separate Python service to apply the AI logic.
