2,300 Weekly Cyberattacks Targeting Travelers

A Check Point investigation reported a surge in travel-related phishing and cyberattacks in May 2026, finding about 2,300 attacks per week in the travel sector — a 24% year‑on‑year increase — while overall attacks across sectors rose only 2%. Check Point also identified roughly 47,300 newly registered domains that mimic hotels, booking platforms and tour operators, including clusters like a single domain with 210 numbered variants and examples such as booking‑jp.com. Many domains are registered but not yet live, suggesting attackers may time launches for peak travel season. The article cites German statistics showing high volumes of online bookings and offers consumer guidance: avoid suspicious links, type known URLs manually, verify site URLs closely, and be wary of pressure tactics like fake time-limited deals.

ChatGPT core update increases German publishers' visibility

SEO firm Sistrix identified what it calls the first documented "core" update in ChatGPT following OpenAI's rollout of GPT-5.5 on 22 May 2026. Sistrix measured a 47% shift in the domain (citation) distribution for German-language ChatGPT answers within 48 hours of the rollout — a change far above the usual 1–2% range — by comparing four-day periods before and after the event and analysing 800,000 responses. German mainstream media, TV and streaming platforms, specialized tools and Reddit gained visibility, while international aggregators (Indeed, Tripadvisor, Expedia) and global platforms (YouTube, Google, Wikipedia) saw double-digit declines. Sistrix cautions the cause may be the model switch or concurrent changes to retrieval/prompt layers.
