    RadioCSIRT English Version - Your Weekly Cybersecurity News for Sunday, January 18, 2026 (Ep. 68)
    Jan 18 2026
    We open this weekly recap with a massive Patch Tuesday from Microsoft, which addressed 114 vulnerabilities, including three zero-days; notably, CVE-2026-20805 is actively exploited in the wild. Infrastructure concerns continued as Cisco patched a critical AsyncOS zero-day exploited by Chinese APT actors, and AWS remediated a "CodeBreach" supply chain flaw in its console CI pipelines.In data privacy and regulation, France’s CNIL imposed a combined $48 million fine on Free and Free Mobile for security failures affecting 24 million subscribers. Meanwhile, Spanish energy giant Endesa disclosed a breach exposing the data of 22 million customers, and a massive scraping incident affected 17.5 million Instagram users.On the threat landscape, Check Point Research analyzed "Sicarii," a new ransomware operation likely acting as a false flag with confused ideological messaging. Physical "Quishing" (QR code phishing) campaigns are surging in France, and the infamous BreachForums hacking community suffered a taste of its own medicine with a leak of its user database. Finally, strategic cooperation strengthens as the UK unveils its Government Cyber Action Plan and Germany partners with Israel to build a "Cyber Dome" defense system.OSINT Sources:📊 Reports, Studies & StrategiesKaspersky Security Bulletin 2025 : https://www.kasbersky.com/about/press-releases/2025_kaspersky-financial-sector-faced-ai-blockchain-and-organized-crime-threats-in-2025SecurityScorecard (via KnowBe4) : https://www.knowbe4.com/hubfs/Financial-Sector-Threats-The-Shifting-Landscape.pdfENISA Threat Landscape 2025 : https://www.enisa.europa.eu/publications/enisa-threat-landscape-2025FS-ISAC : https://www.fsisac.com/knowledge/annual-navigating-cyber-2025-reportRESCO Courtage : https://www.resco-courtage.com/dora-reglementation-guide-complet-2025NCSC UK : https://www.ncsc.gov.uk/blog-post/government-cyber-action-plan-strengthening-resilience-across-uk🛡️ Vulnerabilities, Patch Tuesday & Security AdvisoriesMicrosoft Security Update Guide : https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-0628CISA (CVE-2025-8110) : https://www.cisa.gov/news-events/alerts/2026/01/12/cisa-adds-one-known-exploited-vulnerability-catalogCISA (CVE-2026-20805) : https://www.cisa.gov/news-events/alerts/2026/01/13/cisa-adds-one-known-exploited-vulnerability-catalogCERT-FR (MISP) : https://www.cert.ssi.gouv.fr/avis/CERTFR-2026-AVI-0030/CERT-FR (VMware) : https://www.cert.ssi.gouv.fr/avis/CERTFR-2026-AVI-0029/CERT-FR (MariaDB) : https://www.cert.ssi.gouv.fr/avis/CERTFR-2026-AVI-0028/CERT-FR (NetApp) : https://www.cert.ssi.gouv.fr/avis/CERTFR-2026-AVI-0027/CERT-FR (Google Pixel) : https://www.cert.ssi.gouv.fr/avis/CERTFR-2026-AVI-0026/Krebs on Security : https://krebsonsecurity.com/2026/01/patch-tuesday-january-2026-edition/Cisco Talos Intelligence : https://blog.talosintelligence.com/microsoft-patch-tuesday-january-2026/CERT Santé : https://cyberveille.esante.gouv.fr/alertes/palo-alto-cve-2026-0227-2026-01-15BleepingComputer (Cisco AsyncOS) : https://www.bleepingcomputer.com/news/security/cisco-finally-fixes-asyncos-zero-day-exploited-since-november/CyberPress (AWS Console) : https://cyberpress.org/aws-console-supply-chain-attack-github-hijackingcyber/⚠️ Data Leaks, Incidents & AttacksBleepingComputer (BreachForums) : https://www.bleepingcomputer.com/news/security/breachforums-hacking-forum-database-leaked-exposing-324-000-accounts/CyberPress (Instagram) : https://cyberpress.org/instagram-data-leak/Cybersecurity Dive (SitusAMC) : https://www.cybersecuritydive.com/news/hackers-steal-sensitive-data-major-banking-industry-vendor-situsamc/BleepingComputer (Endesa) : https://www.bleepingcomputer.com/news/security/spanish-energy-giant-endesa-discloses-data-breach-affecting-customers/BleepingComputer (Pax8) : https://www.bleepingcomputer.com/news/security/cloud-marketplace-pax8-accidentally-exposes-data-on-1-800-msp-partners/The Record (Anchorage Police) : https://therecord.media/anchorage-police-takes-servers-offline-after-third-party-attack🕵️ Threat Intelligence (APT, Ransomware, Phishing)Planet.fr (Quishing Scam) : https://www.planet.fr/societe-arnaque-a-la-fausse-carte-bancaire-par-courrier-le-mecanisme-du-quishing-qui-vise-vos-coordonnees.2992374.29336.htmlCheck Point Research (Sicarii) : https://research.checkpoint.com/2026/sicarii-ransomware-truth-vs-myth/Cisco Talos Intelligence (UAT-8837) : https://blog.talosintelligence.com/uat-8837/Malwarebytes (LinkedIn Phishing) : https://www.malwarebytes.com/blog/news/2026/01/phishing-scammers-are-posting-fake-account-restricted-comments-on-linkedin⚖️ Regulations, Sanctions & International CooperationThe Record (CNIL/Free Fine) : https://therecord.media/france-data-regulator-fineMalwarebytes (Datamasters Fine) : https://www.malwarebytes.com/blog/news/2026/01/data-broker-fined-after-selling-alzheimers-patient-info-and-millions-of-sensitive-profilesThe Record (Germany-Israel Deal) : https://therecord.media/...

    Jan 11 2026
    We open this episode with a new physical mail scam campaign targeting bank customers in France, according to Planet.fr. The modus operandi begins with the receipt of a letter bearing the letterhead of a financial institution and containing a fake bank card equipped with a chip. The document instructs the recipient to scan a QR code to activate the card. This technique, known as “quishing,” redirects the victim to a malicious website designed to exfiltrate personal data and banking details. The phenomenon, already observed in neighboring European countries, is gaining ground in France. The cards display a high level of counterfeiting, including accurate reproduction of banks’ visual identities. Verifying the URL displayed after scanning the QR code is the first indicator of legitimacy. If information is entered on a fraudulent website, the recommended procedure includes immediately blocking the bank card, changing all passwords, and reporting the incident via the French Interior Ministry’s Perceval platform.Microsoft published CVE-2026-0628 in its Security Update Guide, concerning a high-severity vulnerability affecting Chromium’s WebView tag component, according to Neowin. The technical flaw, classified as “Insufficient policy enforcement,” allows an attacker who has convinced a user to install a malicious extension to inject scripts or HTML into a privileged page. Researcher Gal Weizman reported the vulnerability to Google in late November. Chrome version 143.0.7499.192 contains the upstream fix, which was integrated by Microsoft into Edge on January 10, 2026. Microsoft records the CVE in its Security Update Guide to provide authoritative downstream status to Edge customers. Canonical vulnerability trackers confirm that the upstream remediation threshold was set in the Chrome 143 stable release. Inventory and remediation efforts must cover all embedded Chromium runtimes and Electron applications, as updating the host browser does not protect these applications.The BreachForums hacking forum suffered a data leak exposing its user database table, according to BleepingComputer. On January 9, 2026, a site named after the ShinyHunters extortion gang published a 7Zip archive named breachedforum.7z. The archive contains the file databoose.sql, a MyBB database table comprising 323,988 member records, including display names, registration dates, IP addresses, and other internal information. Analysis shows that the majority of IP addresses resolve to a local loopback address, but 70,296 records contain public IP addresses. The latest registration date corresponds to August 11, 2025, the day the previous BreachForums was shut down following the arrest of certain alleged operators. The current administrator, known under the pseudonym N/A, acknowledged the leak, stating that a backup of the MyBB users table was temporarily exposed in an unsecured directory and downloaded once.Finally, a major data leak compromised the personal information of approximately 17.5 million Instagram users, according to CyberPress. The leak, initially reported by cybersecurity researchers at Malwarebytes, exposes contact information, making millions of users vulnerable to identity theft and targeted phishing attacks. The dataset appeared this week on a hacking forum, published by a threat actor using the pseudonym “Solonik.” The listing titled “INSTAGRAM.COM 17M GLOBAL USERS — 2024 API LEAK” contains 17.5 million records formatted in JSON and TXT files. The data was collected in late 2024 via an API leak that bypassed standard security measures. The exposed database includes full names, usernames, verified email addresses, phone numbers, user identifiers, and partial location data. The leak is classified as scraping, meaning automated data collection via public interfaces. As of January 10, 2026, Meta has not issued a formal statement regarding this leak.SourcesPlanet.fr – Bank card scam https://www.planet.fr/societe-arnaque-a-la-fausse-carte-bancaire-par-courrier-le-mecanisme-du-quishing-qui-vise-vos-coordonnees.2992374.29336.htmlMicrosoft Security Update Guide – CVE-2026-0628 https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-0628 BleepingComputer – BreachForums database leak https://www.bleepingcomputer.com/news/security/breachforums-hacking-forum-database-leaked-exposing-324-000-accounts/ CyberPress – Instagram data leak https://cyberpress.org/instagram-data-leak/Don’t think, patch!Your feedback is welcome.Email: radiocsirt@gmail.comWebsite: https://www.radiocsirt.comWeekly Newsletter: https://radiocsirtenglishedition.substack.com/

    RadioCSIRT – English Edition – Your Cybersecurity News for Saturday, January 10, 2026 (Ep. 66)
    Jan 10 2026
    We open this edition with a global overview of the current cyber threat landscape.The year twenty twenty five confirms a high and persistent level of cyber pressure on organizations, characterized by the convergence of critical technical vulnerabilities, structural dependencies on suppliers, and growing geopolitical tensions. Sector-wide analyses highlight a continuous expansion of attack surfaces, increased exploitation of digital supply chains, and sustained professionalization of malicious actors, whether criminal or state-sponsored.We then move on to an in-depth analysis of the financial sector, facing a dual structural threat.Reports from Kaspersky, ENISA, FS-ISAC, and KnowBe4 converge on a clear conclusion: nearly all major financial institutions have been affected by incidents involving third-party providers. This systemic exposure is accompanied by an intensification of geopolitically motivated attacks and APT operations targeting international banking infrastructures, notably for state financing or intelligence collection purposes.We also revisit several documented incidents illustrating this dynamic.The compromise of the banking vendor SitusAMC highlights the cascading effects of supply chain attacks.The attack claimed by the pro-Russian group NoName057(16) against La Poste fits into a logic of symbolic disruption linked to geopolitical tensions.Other recent cases reported by specialized media confirm the sustained exposure of the financial sector to attacks combining organized cybercrime and state-level objectives.Finally, we address the regulatory and organizational response to these threats.The DORA regulation represents a structuring step for the operational resilience of the European financial sector, but feedback shows that compliance alone is not sufficient to counter determined adversaries. Mastery of digital dependencies, visibility over third and fourth parties, and the strengthening of detection and response capabilities remain central challenges to limit systemic impact.ations.Sources:Sectoral Reports and Threat Analyses:Kaspersky Security Bulletin 2025 - Financial Sector: https://www.kaspersky.com/about/press-releases/2025_kaspersky-financial-sector-faced-ai-blockchain-and-organized-crime-threats-in-2025ENISA Threat Landscape 2025 - Finance Sector: https://www.enisa.europa.eu/publications/enisa-threat-landscape-2025FS-ISAC - Navigating Cyber 2025: https://www.fsisac.com/knowledge/annual-navigating-cyber-2025-reportKnowBe4 - Financial Sector Threats: The Shifting Landscape: https://www.knowbe4.com/hubfs/Financial-Sector-Threats-The-Shifting-Landscape.pdfDocumented Incidents and Compromises:Cybersecurity Dive - SitusAMC Banking Vendor Breach: https://www.cybersecuritydive.com/news/hackers-steal-sensitive-data-major-banking-industry-vendor-situsamc/The Record (Recorded Future) - NoName057(16) Attack on La Poste: https://therecord.media/pro-russian-hackers-claim-attack-french-postal-service-la-posteAmerican Banker - Marquis Breach (Carter Pape): https://www.muckrack.com/carter-pape/articlesAttribution and State Threat Actors:Security Affairs - France Links APT28 to Government Attacks: https://securityaffairs.com/171234/apt/france-links-russian-apt28-attacks.htmlCompliance and Regulation:RESCO Courtage - Complete DORA Guide 2025: https://www.resco-courtage.com/dora-reglementation-guide-complet-2025L'Usine Digitale - 2025 Cyberattacks and Lessons Learned: https://www.usine-digitale.fr/article/les-cyberattaques-qui-ont-marque-l-annee-2025-et-les-lecons-a-en-tirer.htmlDon’t think, patch!Your feedback is welcome.Email: radiocsirt@gmail.comWebsite:https://www.radiocsirt.comWeekly Newsletter:https://radiocsirtenglishedition.substack.com/
