Firmy muszą dziś prowadzić spójny rejestr aktywów, procesów i dostawców oraz na bieżąco raportować zagrożenia. W tym kontekście pojawiła się aplikacja Red Into Green (RIG) – platforma LegalTech automatyzująca analizę ryzyka i tworzenie planów zarządzania zgodnie z europejskimi przepisami. RIG udostępnia m.in. raporty w czasie rzeczywistym, dynamiczne analizy ryzyka oraz uporządkowany rejestr procesów i aktywów. Produkty RIG: DORA, NIS i GDPR Produkty RIG prowadzą przez […] - [Preparing for the Quantum Era: How Companies Should Rethink Cybersecurity](https://karacena.eu/preparing-for-the-quantum-era-how-companies-should-rethink-cybersecurity/): The quantum computing era, although not yet fully realized, is already influencing how organizations should think about security. In this article, I explore the threats that quantum technologies pose to businesses, who will be affected, and what can be done today to prepare for the future. Quantum Threats on the Horizon Breaking the Foundations of Modern Cryptography The most critical threat posed by quantum computers is their potential to break the cryptographic algorithms that currently protect our digital world.Shor’s algorithm allows efficient factorization of large numbers and solving of discrete logarithm problems — the mathematical foundations of RSA and Elliptic […] - [CVE‑2025‑59287: Understanding the WSUS Remote Code Execution Vulnerability and Protecting Your Organisation](https://karacena.eu/wsus-remote-code-execution/): Introduction In October 2025 a critical remote‑code‑execution (RCE) bug in Windows Server Update Services (WSUS) shook the security community. The flaw, tracked as CVE‑2025‑59287, resides in WSUS’s handling of encrypted AuthorizationCookie data. An unauthenticated attacker can send a specially crafted SOAP request and trigger unsafe deserialization in the WSUS service, leading to arbitrary code execution with SYSTEM privileges. Because WSUS acts as the central hub for distributing Microsoft updates across enterprise networks, a compromised server can become a conduit for supply‑chain attacks. This article compiles the latest information, proof‑of‑concept (PoC) details, expert commentary, case studies and immediate actions, and provides best‑practice […] - [Nowelizacja ustawy o Krajowym Systemie Cyberbezpieczeństwa: co oznacza dla firm i sektora publicznego?](https://karacena.eu/pl/nowelizacja-ustawy-o-krajowym-systemie-cyberbezpieczenstwa-co-oznacza-dla-firm-i-sektora-publicznego/): Polski rząd uczynił kolejny krok w kierunku wzmocnienia odporności cyfrowej państwa. 21 października 2025 r. Rada Ministrów przyjęła projekt nowelizacji ustawy o Krajowym Systemie Cyberbezpieczeństwa (KSC). Zgodnie z zapowiedzią wicepremiera i ministra cyfryzacji Krzysztofa Gawkowskiego projekt ma zostać uchwalony jeszcze w tym roku. Uchwała przekazano do Sejmu i Senatu, a premier Donald Tusk podkreślił, że cyberbezpieczeństwo jest kluczowe dla bezpieczeństwa wewnętrznego i zewnętrznego kraju. Aktualne informacje Adoptowany projekt wynika z pilnej potrzeby dostosowania polskiego prawa do dyrektywy UE 2022/2555 (NIS 2) oraz narastającej skali zagrożeń w sieci. Według statystyk CSIRT NASK w 2022 r. zgłoszono ponad 39 tys. incydentów cyberbezpieczeństwa, a w 2023 r. ponad 75 tys. – wzrost o ponad 90 %. W 2024 r. do CERT Polska trafiło już ponad 600 tys. zgłoszeń incydentów (62 % więcej niż rok wcześniej). Jednocześnie tylko […] - [Fake LastPass & Bitwarden Breach Alerts](https://karacena.eu/fake-lastpass-bitwarden-breach-alerts/): The latest threat landscape On October 15 2025 BleepingComputer broke the news that attackers had launched a convincing phishing campaign aimed at users of LastPass and Bitwarden—two of the most popular password managers. E‑mails arriving from domains such as lastpasspulse[.]blog and bitwardenbroadcast[.]blog falsely warned users that the companies had suffered security breaches and urged recipients to download a “secure desktop app.” The messages were carefully crafted; they mimicked official branding, claimed that outdated .exe versions were vulnerable, and directed victims to a download link. BleepingComputer’s researchers found that both the LastPass‑ and Bitwarden‑branded campaigns used identical messages and even targeted […] - [Agentic AI – Ally or Adversary? Navigating the New Player in Cybersecurity](https://karacena.eu/agentic-ai-ally-or-adversary-navigating-the-new-player-in-cybersecurity/): Agentic artificial intelligence – AI systems capable of setting goals, devising strategies and executing actions without constant human oversight – is no longer science fiction. As generative AI exploded into the mainstream and cybersecurity platforms began to sprinkle “AI‑powered” on every dashboard, a more advanced class of agents quietly emerged. These agentic AI systems are designed to think and act autonomously. In cybersecurity they promise to supercharge threat detection, triage endless alerts and even respond to attacks in real time, but they also raise uncomfortable questions about safety, trust and control. We researched the latest news and expert commentary to […] - [RediShell (CVE‑2025‑49844)](https://karacena.eu/redishell/): Overview A critical remote‑code execution (RCE) vulnerability dubbed RediShell (CVE‑2025‑49844) recently sent shockwaves through the cloud‑security community. Discovered by the Wiz research team and demonstrated at Pwn2Own Berlin, the bug has been lurking in the Redis in‑memory database for more than 13 years. It arises from a use‑after‑free flaw in Redis’s embedded Lua scripting engine. When an authenticated user sends a specially crafted Lua script, the garbage‑collection routine frees a still‑live object; an attacker can then reuse the dangling pointer to escape the Lua sandbox and run native code on the host.  Because Redis does not enable authentication by default, […] - [Case Study - When a new employee turns out to be a North Korean cybercriminal](https://karacena.eu/case-study-nk-cybercriminal/): Imagine you’ve just hired a new IT specialist. Their CV looks great, their references are impeccable, and the interview was professional. You send them a laptop, provide access to their systems, and… a few days later, your SOC (or external IT provider) notices the installation of strange software. This isn’t a scene from an action movie. One of our clients, a technology company that’s a leader in its own industry, experienced this very situation. Why does North Korea’s „IT worker factory” work? Let’s start from the beginning to better understand the situation. We constantly hear about hacks, 0-days, phishing attacks, […] - [Scattered Spider – Cybercriminals with a lot of nerve (and a lot of skill)](https://karacena.eu/scattered-spider/): Recent weeks in the world of cybersecurity have shown one thing: the Scattered Spider group has no intention of letting up. On the contrary, they’re accelerating. The FBI and CISA are sounding the alarm, and we’re seeing an increase in reports from companies that have fallen victim to their clever (and unfortunately effective) tactics. According to TechRadar, their attack campaigns are expected to intensify in the coming months. If you haven’t heard of Scattered Spider yet, it’s time to catch up. Who are Scattered Spiders? Scattered Spider is an international cybercriminal group that experts classify as belonging to a broad […] - [Privacy-Focused Web Browsers: Firefox, LibreWolf, Tor & Focus](https://karacena.eu/privacy-focused-web-browsers/): As part of our ongoing series on tools that protect your digital privacy and security, this edition focuses on web browsers—your gateway to the internet.

Introducing NIS2 – a new EU directive that will come into force in 2024/2025 and will affect significantly more companies than its predecessor, NIS1. But don’t worry – you don’t have to hire an army of experts right away. What is NIS2? NIS2 is the EU’s Network and Information Security Directive. It was adopted to improve overall digital resilience in Europe. It improves and expands on previous legislation (NIS1) because, well… […] - [Privacy in Your Browser: Essential Extensions](https://karacena.eu/privacy-in-your-browser-essential-extensions/): This article continues our series on practical tools that enhance digital privacy and security – both in the workplace and at home.

The year 2025 is a real show of force for cybercriminals, who are constantly pulling out new tools and spectacular vulnerabilities from their sleeves. Just look at a few examples of attacks and zero-day vulnerabilities: RansomHub – a ransomware group that carried out high-profile attacks on healthcare and education companies in 2025, encrypting data and threatening to publish stolen information. QakBot is back – Following last year’s FBI operation, the QakBot malware returned in 2025 in a new version, spread via infected LinkedIn webpage. Zero-day in […] - [Why You Need a Password Manager For Work and Personal Security](https://karacena.eu/password-manager/): Welcome to the first installment in our new blog series dedicated to exploring tools that enhance digital privacy and cybersecurity – both in the workplace and at home.

The publicly disclosed vulnerability earlier this year has been exploited in the wild already by attackers. It allows attackers to remotely execute malicious code, putting company systems, data, and operations at significant risk. What happened? The vulnerability stems from improper input validation in certain ASP.NET applications. When user input isn’t properly validated, attackers can inject malicious commands that execute with elevated privileges. Cybercriminals are actively scanning for exposed servers to:      Install malware   […] - [Utilizing AI in Organizations: Benefits, Risks, and Safe Implementation](https://karacena.eu/ai-in-organizations/): Artificial intelligence (AI) is transforming the operations of organizations, offering a number of benefits, but not without risk.
