AI Security Takes Centre Stage: Hackers Warn Systems Are Still Shockingly Vulnerable

2025 marks a dramatic shift in the AI landscape—what was once a dialogue about AI “safety” has quickly transformed into a focus on AI “security.”

Since the debut of ChatGPT in late 2022, conversations around AI have often veered into the hypothetical, with alarmist warnings about existential threats: rogue AI causing global crises, or out-of-control systems undermining humanity. But in a surprising turn, the real and immediate security risks AI poses have begun to dominate discussions.

The State Of AI Security: Far From Secure

Security experts are making it clear: AI systems remain frighteningly easy to manipulate. These tools—designed to power everything from chatbots to self-driving cars—are still riddled with vulnerabilities. At this point, hackers can trick large language models (LLMs) into providing detailed guides on cyberattacks or exposing sensitive data. The risk is not just theoretical—deepfake videos could spread fake news, or chatbots could be weaponized for scams. These aren’t future threats—they’re happening now.

Even as companies scramble to patch AI security holes, a report from the 2024 Def Con hackers’ conference points out that current defenses are woefully inadequate. Despite the best efforts of ethical hackers, AI models continue to be alarmingly easy to break into, with major flaws still slipping under the radar.

Why Red-Teaming Isn’t Enough

At the heart of AI security efforts is a practice called “red teaming,” where companies stress-test their models by simulating potential attacks. The aim is to uncover weaknesses like misinformation, privacy leaks, or manipulation of model behavior. However, experts like Sven Cattell, founder of Def Con’s AI Village, aren’t convinced. Cattell argues that the current process is deeply flawed—AI systems are too complex and unpredictable for red-teaming to catch every potential vulnerability. He points out that no team, regardless of its size or expertise, can predict all how AI might be exploited. As he puts it, the unknowns in AI security will always outpace testing efforts.

Collaboration Is Key To AI Security

The way forward, Cattell insists, is collaboration. Just like traditional cybersecurity, AI security requires shared knowledge and a more coordinated approach to identifying and fixing vulnerabilities. Without a standardized system for reporting AI flaws and a public database to track these issues, the security of these systems will remain in jeopardy. Without this cooperation, AI will never be fully secure.

To truly safeguard AI models, experts urge the creation of dedicated frameworks, allowing developers to share vulnerabilities and fix them collectively. This is not just about building a secure system; it’s about creating a culture of collaboration across industries to prevent AI from being exploited by malicious actors.

In a world where AI’s role continues to expand, its security must become just as sophisticated as the systems it powers. Now is the time to act before these vulnerabilities spiral into real-world dangers.

Bank of Cyprus Upgrade Signals Fresh Optimism For Greek And Cypriot Banks

Regional Banks Enter A More Favorable Cycle

Bank of Cyprus and Eurobank are well positioned to benefit from a renewed re-rating of Greek and Cypriot bank stocks, according to Cyprus-based investment firm Roemer Capital, which upgraded Bank of Cyprus to a buy rating and reaffirmed its positive view on Eurobank.

The firm cited easing geopolitical tensions, resilient economic growth in Greece and Cyprus, lower funding costs and Greece’s expected transition to developed-market status as the main factors supporting the sector.

Roemer Capital also lowered its cost of equity assumptions, updated its forecasts following first-quarter 2026 results and extended its valuation horizon to the end of 2027, raising target prices across its banking coverage.

Bank Of Cyprus Gets The Largest Upgrade

Bank of Cyprus received the biggest revision, with Roemer Capital upgrading the stock from hold to buy and setting a target price of €11.10, implying potential total upside of 27%.

The firm highlighted the bank’s strong capital generation, profitability and projected 100% dividend payout, describing it as the strongest capital-return story among the banks under coverage. Roemer Capital maintained its buy rating on Eurobank, assigning a target price of €4.90 and forecasting potential upside of 28%. The report said the bank is well placed to benefit from loan growth, improving operating performance and merger-and-acquisition synergies.

National Bank of Greece and Piraeus Bank also retained buy ratings, with expected returns ranging from 25% to 36%. Optima Bank was upgraded to buy, while Alpha Bank remained at hold on valuation grounds.

Why Growth Still Sets The Region Apart

According to Roemer Capital, Greek and Cypriot banks continue to benefit from stronger economic fundamentals than many western European peers. The report pointed to faster economic growth, healthier balance sheets, low levels of non-performing exposures, capital ratios approaching 20% and strong customer deposit bases.

Analysts expect performing loans across the sector to grow at a compound annual rate of 6% to 8% through 2028, supported by private investment, digitalisation, green manufacturing, supply-chain expansion and a gradual recovery in household lending.

The report also said the conclusion of lending under the EU Recovery and Resilience Facility is unlikely to materially affect credit growth, as banks have already shifted back towards traditional commercial lending. Roemer Capital expects Euribor to remain between 2.2% and 2.5%, a level it believes should support both lending activity and net interest margins.

Geopolitics, Valuation And Market Structure Support The Case

The report said improving geopolitical conditions have strengthened the investment outlook, noting that Brent crude prices have largely returned to pre-war levels while Greek government bond yields have stabilised at around 3.5%. Although geopolitical risks remain, Roemer Capital believes the likelihood of a major inflationary shock or significant pressure on bank profitability has eased.

Another important catalyst identified by the firm is Greece’s expected promotion to developed-market status by FTSE Russell, STOXX and MSCI over the coming months.

According to the report, the reclassification should improve liquidity and attract a broader base of international investors. Roemer Capital also said Euronext’s acquisition of the Athens Exchange is expected to strengthen market infrastructure and increase international visibility, particularly for Bank of Cyprus and Optima Bank.

The firm noted that Bank of Cyprus has already benefited from its Athens listing, with average daily trading value increasing from less than €400,000 before its September 2024 move to nearly €6 million afterwards.

Economic Momentum Remains A Core Tailwind

Roemer Capital said both Greece and Cyprus have moved beyond post-crisis recovery and are now supported by private-sector-led growth. For Cyprus, the report highlighted recent tax reform and efforts to simplify the legal and regulatory framework, while also noting that limited foreign banking competition continues to support domestic lenders.

Overall, Roemer Capital expects Greek and Cypriot banks to remain well-positioned for profitable loan growth over the coming years.
