Last Notes npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy I still don’t understand why some bots try to enumerate everything via the Vulnerability-Lookup API when full dumps, including all metadata, are available in one shot: https://vulnerability.circl.lu/dumps/ We currently don’t rate-limit bots, but we’re close to doing so. #bot #internet npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy If someone comes to me today preaching about “post-quantum” security issues, I’ll remind them of the current state of security: the npm ecosystem gets abused daily, CI pipelines run left and right with full access to cloud services, so-called security devices like F5 and Ivanti are exposed (and compromised) to the internet, mailboxes get compromised just to change an IBAN in a PDF, and a simple phone call is still enough to get someone to hand over an MFA code. But yes, by all means, let’s focus on post-quantum threats while handing AI tools SSH access like it’s a feature, not a confession. #cybersecurity #stateoftheworld https://media.infosec.exchange/infosec.exchange/media_attachments/files/116/322/174/707/797/506/original/b2c8beec36c42e77.png npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy I'm happy to announce the long-awaited first release of misp-modules-cli version 1.0.0. This initial release makes it nifty and convenient to use MISP expansion modules directly from the command line, whether you are working against a local or remote misp-modules service. The goal is simple: bring the power of misp-modules into a lightweight CLI workflow that is easy to script, automate, and integrate into daily analysis work. #misp #mispmodules #threatintelligence #threatintel #opensource #cli #cybersecurity #osint @nprofile…d0je 🔗 Release note https://github.com/MISP/misp-modules-cli/releases/tag/v1.0 :github: misp-modules-cli https://github.com/MISP/misp-modules-cli :github: misp-modules https://github.com/MISP/misp-modules npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy @nprofile…fm04 It’s actually quite simple: we have a compromised server (VPS or similar) running installed software. My goal was to compare the official SBOM with the system to determine which files belong to the official distribution and which do not. But without file hashes in the SBOM, how can we tell what has been tampered with? SBOMs are often described as manifests, yet they lack the basic capability to verify what is actually in a package. Reconstructing a trustworthy signature from a random list of files also sounds like a significant forensic challenge. I’m wondering if extending an SBOM standard with the hashlookup standard could be a quick way to solve the issue. https://www.ietf.org/archive/id/draft-dulaunoy-hashlookup-format-00.html npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy Have you ever tried doing digital forensics using an SBOM or even just gathering evidence for a technical investigation from one? No file hashes, a single cryptographic signature covering an arbitrary set of files, and often missing full paths or permissions. Many SBOM standards need a serious revamp if they are to support DFIR use cases #dfir #sbom #openstandard npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy The Greenland sea cables are probably being closely monitored, but redundancy seems minimal likely limited to OneWeb satellite connectivity and some VSAT links. Looking at the routing side, AS8818 announces just two /19s and one /22 (and two /32s in IPv6) with a single upstream provider, Level 3 Inc. This suggests that Layer 3 redundancy is even more constrained. I would have expected at least one EU-based provider as an additional upstream... 🔗 https://bgpranking.circl.lu/asn?asn=8818 #greenland #threatintelligence #cybersecurity #seacables https://media.infosec.exchange/infosec.exchange/media_attachments/files/115/861/051/695/538/276/original/412c86e7ee703411.png https://media.infosec.exchange/infosec.exchange/media_attachments/files/115/861/051/698/002/855/original/a7b835b3c9386fd5.png https://media.infosec.exchange/infosec.exchange/media_attachments/files/115/861/051/702/702/831/original/0c503e020d303d99.png https://media.infosec.exchange/infosec.exchange/media_attachments/files/115/861/096/317/544/716/original/8313749705e09ab1.png npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy @nprofile…duyn The EU is documenting threat-actor activity linked to the GRU operating in Europe.

Given that after 20 years and hundreds of millions of dollars spent researchers have yet to demonstrate a single legitimate cryptanalysis result using a quantum physics experiment, it's a bit like arguing over which brand of unicorn repellent is the most cromulent. The current state of things in terms of pure vs. hybrid systems seems to be: - Governments = Pure: “We’re putting all our eggs in one basket and hoping that the dial stops spinning at ‘not broken’” - Everyone else = Hybrid: “We trust this new stuff so little that we’re requiring you use the crypto that we claim is broken alongside it” Peter. #cryptography #pq #postquantum #postquantumcryptography https://www.metzdowd.com/pipermail/cryptography/2025-October/039129.html https://media.infosec.exchange/infosec.exchange/media_attachments/files/115/484/165/861/731/308/original/37fde305bc3b500f.png npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy Imagine a threat intelligence report that concludes, ‘The target is three hops away, therefore it is the correct one.’ This is the method the Pentagon reportedly uses today: not only to identify targets, but also to justify and execute strikes. 🔗 https://theweek.com/politics/pentagon-name-boat-strike-casualties Remember the tertiary people contacted and referenced in some interception cases in intelligence: https://www.atlanticcouncil.org/blogs/new-atlanticist/three-hops-and-you-re-out/ Now it’s actually direct strikes on the tertiary people. #threatintelligence #threatintel #us https://media.infosec.exchange/infosec.exchange/media_attachments/files/115/478/781/615/942/688/original/589c96d354e84bd7.jpeg npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy One year, I had a chat with the fine people @nprofile…sj5h during the @nprofile…r828 conference, and they were wondering why we didn't create an open source website for all the different rules (YARA, Suricata, and many others) — a place to allow comments, reviews, bundling, and integration with @nprofile…3gfz.

VSAT vendors used to love their walled gardens: pseudo-standard DVB-S2 implementations, broken encryption everywhere, and zero cooperation on security, all to protect their proprietary turf.

In addition, the overall cost on third-party organisations doing incident response should not exclude the impact of false-positive reports, pre-notifications of phishing campaigns, or even worse, attackers abusing such awareness campaigns. #cybersecurity #infosec 🔗 https://people.cs.uchicago.edu/~grantho/papers/oakland2025_phishing-training.pdf npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy A new open source cyber-range platform released at the @nprofile…w5se and presented at the cybersecurity track. https://github.com/range42 It seems very promising. @nprofile…eg7d @nprofile…a0tg #cyberrange #cybersecurity #opensource npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy Finally a useful magic quadrant Thanks to @nprofile…dceh for the discovery. #cybersecurity #vulnerability https://media.infosec.exchange/infosec.exchange/media_attachments/files/115/008/670/175/980/149/original/6909f753c4ce0b8c.png npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy When I added the threat-actor @nprofile…39xm galaxy type on Mar 4, 2016, I didn’t expect that, years later, vendors would still invent new names for already known threat actors, avoid using UUIDs, reuse similar names for different actors, and create confusing names by mixing tools or software used by the actors. That’s why we continue the tedious work of maintaining a proper threat-actor database, with relationships to other galaxies such as MITRE ATT&CK, Malpedia, and more. After years of this monastic effort, we’re seeing the benefits—many open-source and proprietary tools now rely on the MISP galaxy, which serves as both an open standard and a public knowledge base. We also maintain a dedicated website for all MISP galaxies. Here’s an example from the threat-actor database: https://www.misp-galaxy.org/threat-actor/relations/fa80877c-f509-4daf-8b62-20aba1635f68/ :github: Repository https://github.com/MISP/misp-galaxy/ 🌐 Public website https://www.misp-galaxy.org/threat-actor/ If you’d like to become a monk (just kidding!) and contribute, feel free to open an issue or submit a pull request on the misp-galaxy repo.

Including an SPDX license reference in the meta field would help clarify how the rules can be used, redistributed, or modified. Thanks a lot for the work! npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy @nprofile…e54t So, could we expect something like Sigma to block or filter LLM interactions? Is there already a standardized format for this? @nprofile…v8y3 you know what to do when you have some free time ;-) npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy @nprofile…e54t I've been wondering about something for a while. We know that SQL injection has been relatively easy to block compared to preventing prompt injection in LLMs, yet we still see SQL injection vulnerabilities after 30 years of defensive and secure coding practices. Do you think it's realistic to assume we'll be able to effectively filter and protect exposed LLMs? npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy @nprofile…70r3 and by the way, we just launched 🔗 https://gcve.eu/ GCVE: Global CVE Allocation System The Global CVE (GCVE) allocation system is a new, decentralized approach to vulnerability identification and numbering, designed to improve flexibility, scalability, and autonomy for participating entities. While remaining compatible with the traditional CVE system, GCVE introduces GCVE Numbering Authorities (GNAs). GNAs are independent entities that can allocate identifiers without relying on a centralised block distribution system or rigid policy enforcement.

However, some legal teams insist on having it “to be on the safe side.” Now it’s very safe indeed. ;-) This particular vulnerability isn’t a big deal since it requires admin rights on WordPress to inject. If you’re already an admin, you can do worse things. The only advantage for attackers is that the injection spreads everywhere. #infosec #gdpr #cybersecurity #vulnerability #wordpress 🔗 https://vulnerability.circl.lu/vuln/CVE-2025-2205 npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy @nprofile…r0kn 😢 npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy @nprofile…qtg4 En effet.

In the light of targeted attacks against journalists, activist, representatives from the civil society and politicians, it empowered incident response team to review device behaviour and ensure their integrity. This tool is initially the result of a joint effort between EC DIGIT CSOC (European Commission DG DIGIT) and CERT-EU (https://cert.europa.eu/). https://hackathon.lu/projects/#sysdiagnose-analysis-framework Don't hesitate to register and add your project! #opensource #dfir #forensic #hackathon #luxembourg Thanks to @nprofile…9xlz and the team to join us. npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy We imported the data from Black Basta Ransomware group leak into AIL and there are many interesting aspects. The federation network of Matrix servers (see the screenshot) used to communicated among the affiliates/group(s). Activities in the chat room, especially the daily activity view in AIL. Guessing the location and timezone of groups or affiliates is an endless source of information. They rely on many open-source and SaaS tools, including Google Docs or Zoom. Many interesting correlations with cryptocurrencies, IP addresses, CVE numbers, and chat username relationships (who talks to whom and when).

While discussing with @nprofile…4m2u about the challenges with CPE values, I used @nprofile…39xm as an example, since we are also the software vendor. CPEs are messy because their creation sources vary, different entities or individuals reporting vulnerabilities. So, it's not always the fault of the CNA or the vendors. We don’t believe that creating a new standard will solve this issue. Instead, we’re working on vulnerability-lookup to extend and update CPE, making it simpler for both vendors and users. If you have any sources for CPE datasets or updated CPE information, please let us know. 🔗 https://www.vulnerability-lookup.org/ #cve #opensource #cpe #vulnerability #cybersecurity https://media.infosec.exchange/infosec.exchange/media_attachments/files/114/001/485/575/160/506/original/51317c0b206d8c72.png npub1l0xa6f4zm4p75c7c3gv69vqmlq23eeked4scppgfx5rhqupams4sdlcq8n Alexandre Dulaunoy @nprofile…5k2y The « bias » one is hilarious.
