Fridges in French supermarkets hit by cyber attack

A BBC News report on a cyber attack that hit hundreds of French supermarkets, causing fridges and freezers to heat up and spoiling fresh and frozen food estimated to be worth millions of euros. Hackers gained control of the software regulating refrigeration temperatures, forcing some units to warm to 50C overnight—one chain's fridges reportedly stayed at that temperature for six hours, and in some places there were even small fires. The attack targeted software from Danish engineering firm Danfoss that lets retailers manage cold units remotely; Danfoss said the affected units were older models whose security software could not be updated to address a risk it had identified, and that it had long advised businesses to keep supported systems up to date. More than 100 Coopérative U supermarkets were targeted, while 180 Intermarché and Netto stores were affected and another 100 were urgently disconnected from the internet. Carrefour, Monoprix, and E.Leclerc were also hit; Carrefour reported 80 of its 6,000 stores affected, and Monoprix 5% of its 400-plus stores. French prosecutors opened a cyber-crime investigation, and European Food Commissioner Christophe Hansen condemned the hack, saying "the weaponisation of food has become a reality."

OWASP ASVS 5.0 Released - Key Updates and What You Need to Know

The OWASP Foundation has released version 5.0 of the Application Security Verification Standard (ASVS), a major update to their security framework for web applications. This new version features restructured security requirements for better clarity, expanded guidance for cloud and API security, improved DevSecOps integration for CI/CD pipelines, updated threat modeling support, and enhanced compliance mapping with standards like NIST and PCI DSS. ASVS serves as a critical benchmark for developers building secure applications, penetration testers conducting security assessments, and auditors performing compliance reviews.  The standard is available for download from the OWASP ASVS project page, with organizations encouraged to integrate it into their software development lifecycles through code reviews and security testing tools. As a vendor-neutral, community-driven project, OWASP continues to welcome contributions to further develop the standard. This release represents an importa...

Critical OpenSSH Flaws Enable MITM and DoS Attacks

On February 18, 2025, HackRead reported on two critical vulnerabilities in OpenSSH, identified by the Qualys Threat Research Unit (TRU). The first vulnerability, CVE-2025-26465, affects the OpenSSH client and permits machine-in-the-middle attacks, potentially allowing attackers to impersonate legitimate servers and compromise SSH session integrity. This flaw exists regardless of the 'VerifyHostKeyDNS' setting and has been present since OpenSSH version 6.8p1. The second vulnerability, CVE-2025-26466, impacts both the client and server, enabling pre-authentication denial-of-service attacks that consume excessive system resources, leading to potential outages. Introduced in version 9.5p1, this issue persists up to version 9.9p1. Users are strongly advised to upgrade to OpenSSH version 9.9p2 to mitigate these vulnerabilities.  https://hackread.com/critical-openssh-flaws-expose-users-mitm-dos-attacks/

MITRE ATT&CK v19 Redefines How Defenders Model Modern Threats

MITRE ATT&CK v19 introduces one of the framework’s most significant structural changes in years, splitting the former Defense Evasion tactic into two clearer categories: Stealth and Defense Impairment. The release also expands coverage for AI-enabled adversary behavior, social engineering, and mobile detection strategies, while adding greater precision to ICS through new sub-techniques. Beyond taxonomy updates, v19 signals a broader evolution of threat modeling—toward more actionable, behavior-driven intelligence that reflects how attackers increasingly blend automation, deception, and cross-domain operations.  https://medium.com/mitre-attack/attack-v19-ff329cb65d66
