Japanese telecommunications operator KDDI has confirmed that more than 12 million users were affected by a cyberattack that took place in June this year. The incident was discovered on June 17, after unknown attackers exploited a so-called zero-day vulnerability in third-party software to gain access to an email system operated by KDDI for five Japanese internet service providers. The company stated that its mobile and fixed-line email services were not affected by the attack, as they operate on separate infrastructure.

According to available information, the email addresses of approximately 12.2 million users were compromised, while the passwords of around 7.6 million accounts also fell into the hands of the attackers. KDDI says the vulnerability was likely exploited as early as May and that the software vendor is currently working on a security patch. In cooperation with the affected internet service providers, the company has already launched a password reset process for users, while the mandatory reset of all compromised accounts is expected to be completed in the coming days.

KDDI claims that the attackers were removed from its systems immediately after the incident was discovered and that there is currently no evidence of any additional suspicious activity. The company has also announced a thorough security review of the affected software and plans to transition to more secure communication technologies in order to prevent similar incidents in the future.

France’s national postal service, La Poste, experienced a significant disruption to its digital infrastructure this week after a large-scale cyberattack temporarily disabled key systems during the peak holiday delivery period. A pro-Russian hacking collective later claimed responsibility for the incident, according to French authorities.

The attack, identified as a distributed denial-of-service (DDoS) operation, forced central IT systems offline on Monday, preventing postal employees from tracking parcels and causing interruptions to online payment services linked to La Poste’s banking division. As of Wednesday morning, parts of the system had not yet been fully restored.

Responsibility for the attack was claimed by the hacker group Noname057, which has previously been linked to a series of cyber operations targeting European institutions. Following the claim, France’s domestic intelligence service, DGSI, assumed control of the investigation, the Paris prosecutor’s office confirmed.

The disruption comes at a critical time for La Poste, which handles billions of mail items and parcels annually and employs more than 200,000 people nationwide. The outage coincided with one of the busiest logistics periods of the year, amplifying its operational impact.

French authorities view the incident within a broader pattern of hostile cyber activity attributed to Russia-aligned actors. France and its European partners argue that such attacks form part of a wider “hybrid warfare” strategy aimed at destabilizing public services, exhausting security resources, and weakening political support for Ukraine. In recent years, European investigators have documented hundreds of similar incidents involving cyberattacks, disinformation campaigns, and acts of sabotage across the region.

A large portion of the global internet experienced significant slowdowns today after Cloudflare, one of the key infrastructure providers behind thousands of popular websites, suffered a major technical outage. The disruption affected numerous online services — including X (formerly Twitter), Substack, Canva and others — with users encountering a “500 internal server error” message instead of the expected content.

Interestingly, some platforms that were impacted by a similar worldwide outage earlier this month remained stable this time, likely because they have since reduced their reliance on Cloudflare’s infrastructure. Among those unaffected was ChatGPT.

This is the second major incident in less than three weeks, once again highlighting the complexity and vulnerability of the global internet ecosystem. Cloudflare provides essential services that act as a “bridge” between websites and their users, accelerating page loading and protecting sites from overload. As a result, any disruption within Cloudflare’s systems can quickly trigger a chain reaction that brings down numerous unrelated services across the internet.

Although the interruption was relatively brief, it underscored how dependent the global digital landscape has become on a handful of key technology providers — and how their technical issues can instantly become a worldwide problem.

At the end of November 2025, Germany initiated the most far-reaching cybersecurity reform of the past decade, following the Bundesrat’s adoption of the NIS2 implementation law. As a result, regulatory obligations effectively entered into force immediately, without any transitional periods — a development legal experts are calling a “compliance shock” for the business sector. At the same time, European supervisory authorities activated a key mechanism of the DORA regulation and published the first list of critical IT third-party providers, who now fall under direct EU oversight.

The Federal Network Agency (BNetzA) has already presented a draft of a new security catalogue, introducing stricter requirements for safeguarding the telecommunications supply chain. The law firm Dentons reminds that all obligations apply the moment the law takes effect, including mandatory registration with the BSI and the implementation of comprehensive cyber risk-management measures. The scope of regulated entities is expanding dramatically — from around 4,500 to almost 30,000 companies — now including logistics, food supply, and digital service providers.

DORA further tightens supervision over cloud providers, analytics companies, and software vendors serving the financial sector, introducing mandatory on-site inspections and new channels for reporting IT incidents. The common priority of both regulations is strengthened third-party risk management, meaning that suppliers can no longer rely on simple declarations of conformity but must provide evidence of their security reliability.

Regulators stress that the era of postponements is over, and companies that were counting on extended deadlines now face severe penalties and increased personal liability for management. All indicators suggest that the period leading into early 2026 will be a race to close compliance gaps across all sectors.

Amazon has released details on two cases in which Iranian threat actors combined digital espionage with physical attacks, a practice the company refers to as “cyber-enabled kinetic targeting.” The first case involves the group Imperial Kitten (also known as Tortoiseshell), linked to Iran’s IRGC, which over a two-year period progressed from cyber reconnaissance to a physical strike. According to Amazon, the group compromised a ship’s AIS system in December 2021 and, by August 2022, had gained access to additional maritime platforms and onboard CCTV cameras to collect real-time visual intelligence. In January 2024, they searched AIS location data for a specific vessel, which just days later, on February 1, became the target of a Houthi missile attack. Amazon says the link between the cyber reconnaissance and the subsequent strike is “unmistakable,” even though the attack itself was unsuccessful.

The second case concerns MuddyWater, a group tied to Iran’s MOIS, which in May 2025 prepared a server for cyber operations and, by June 17, used the same infrastructure to access a compromised CCTV server streaming live footage from Jerusalem. Researchers believe the footage was used to support the planning of a June 23 missile attack, after which Israeli authorities warned citizens to immediately disconnect internet-exposed cameras. Amazon stresses that existing terms such as “cyber-kinetic operations” or “hybrid warfare” lack precision, and proposes a new definition for campaigns where cyber activities directly support physical strikes. The company warns that this type of operation will become increasingly common as nation-states recognize the strategic advantage of combining digital reconnaissance with kinetic attacks.

Amazon urges companies to adjust their security strategies and expand threat models, noting that even entities that previously considered themselves uninteresting to attackers may now be targeted for tactical intelligence collection.
