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.
The Check Point research highlights rising phishing and domain‑cloning activity targeting travel customers, which increases fraud risk, undermines consumer trust in travel platforms and can affect conversion and brand safety for advertisers and publishers operating in travel and related ad inventory.

Report: Trojans and Online Fraud Surge in Germany
The Gen Threat Report H1 2026 shows a marked increase in cybercrime in Germany, with attackers shifting from classic malware to deception that exploits trusted platforms and processes. The report documents large percentage increases in droppers (+160%), trojans (+145%), and online-shop fraud (+134%), plus rises in remote access trojans (+69%) and phishing (+47%). Germany saw 2.3 million tech-support-fraud attacks blocked in the first half of 2026 (third highest globally). Globally, analysts blocked over 114 million fake-shop attacks and observed rising web-skimming, identity fraud, tracking attempts and misuse of AI agents as an emerging attack surface.
Booking.com confirms customer data breach
Booking.com confirmed that unauthorized third parties may have accessed customers' booking information, including names, email addresses, phone numbers, and reservation details. The company notified affected customers this week and said it updated PIN numbers for impacted reservations after detecting suspicious activity. A user reported receiving a WhatsApp phishing message containing booking details, suggesting attackers are leveraging stolen data for targeted scams. Booking.com declined to disclose how many customers were affected; the company told The Guardian that financial information was not accessed and later clarified physical addresses were not taken. TechCrunch notes prior incidents in 2024 where hotel systems were infected with consumer-grade spyware (pcTattletale) that captured Booking.com admin portal screenshots.
Account Fraud and Phishing Surge in 2025
A t3n report highlights a marked rise in account- and card-related fraud, driven by phishing and smishing attacks that increasingly use AI to personalize messages. Germany’s police statistics (PKS) recorded about 96,400 cases around accounts and payment cards in 2025, a ~5% increase year-on-year, and total losses reached roughly €2.25 billion (up ~65%). Detection and prosecution rates remain low: only about 20% of cases overall led to suspects being identified, and cases likely originating abroad had an investigation rate of just 1.4%. Consumer advocates say banks often refuse reimbursements by alleging gross negligence; the Verbraucherzentrale Bundesverband (vzbv) reported a 54% rise in cybercrime complaints related to financial services. Authorities warn the true number of incidents is much higher because many victims do not file reports.
