An adaptive indoor positioning system based on Bluetooth Low Energy RSSI
Politecnico di Milano, Technical Report / MSc Thesis
See publicationThe goal of indoor positioning in some applications, notably oriented to hospitals and malls, is to monitor people into a structure or provide navigation support, others want to use indoor positioning to better understand how customers behaves, enhance their satisfaction, branding and marketing for the venue, provide just-in-time information (for instance, intelligent audio guides for tours) or offer, by the means of location information, video or augmented reality experiences or connect people…
The goal of indoor positioning in some applications, notably oriented to hospitals and malls, is to monitor people into a structure or provide navigation support, others want to use indoor positioning to better understand how customers behaves, enhance their satisfaction, branding and marketing for the venue, provide just-in-time information (for instance, intelligent audio guides for tours) or offer, by the means of location information, video or augmented reality experiences or connect people of interest in proximity to each another. In other words, indoor positioning systems (IPSs) enable location-awareness for mobile devices in ubiquitous and pervasive wireless computing systems. The need for connectivity, access and navigation has fueled research and investments in this field. A different and innovative solution for developing an indoor positioning system (IPS) could be based on the adoption of a low-cost transmitting infrastructure, based on a limited number of Bluetooth Low Energy (BLE) beacons, not requesting to the installer any effort (no on-site surveys) by defining a real-time and environment-adaptive signal propagation model, based on the evolution of Received Signal Strengths Indicator over time.

Semantic Clustering for Complex Data Items
Politecnico di Milano, Technical Report
See publicationSemantic clustering is a software technique (a class of algorithms and methods) that aims to group source artefacts (e.g., sentences, user profiles, items) based on their semantic value. This concerns with partitioning points of a data set into distinct groups (clusters) such that two points from one cluster are semantically similar to each other whereas two points from distinct clusters are not. In order to do this, a similarity measure is required to be passed as input to the clustering…
Semantic clustering is a software technique (a class of algorithms and methods) that aims to group source artefacts (e.g., sentences, user profiles, items) based on their semantic value. This concerns with partitioning points of a data set into distinct groups (clusters) such that two points from one cluster are semantically similar to each other whereas two points from distinct clusters are not. In order to do this, a similarity measure is required to be passed as input to the clustering function. In this report I am trying to investigate about key features of complex data semantic classification models and their main operational aspects. The goal of these techniques, different from the classical data mining approaches, is to discover a path to a more wide and general knowledge taking advantage of the meanings related to the components and associating them with each semantic unit.

Extracting Information from Google Fusion Tables
Search Computing : Broadening Web Search / Ed. Springer
With Fusion Tables, Google has made available a huge repository that allows users to share, visualize and manage structured data. Since 2009, thousands of tables have been shared online, encompassing data from virtually any domain and entered by all kinds of users, from professional to non-experts. While Fusion Tables are a potentially precious source of freely available structured information for all sorts of applications, complex querying and composing them is not supported natively, as it…
With Fusion Tables, Google has made available a huge repository that allows users to share, visualize and manage structured data. Since 2009, thousands of tables have been shared online, encompassing data from virtually any domain and entered by all kinds of users, from professional to non-experts. While Fusion Tables are a potentially precious source of freely available structured information for all sorts of applications, complex querying and composing them is not supported natively, as it requires understanding both the structure and content of tables’ data, which are heterogeneous and produced "bottom-up". In this paper, we discuss ongoing and future work concerning the integration of Fusion Tables in the aim of efficiently integrating, visualizing, and querying them.

Today I read about a mistake that was made at Google cloud: https://lnkd.in/eCPshqsU. Luckily whitesky.cloud users are protected for such a mistake through the Recyle Bin feature. When deleting any resource, it is only "soft" deleted, and it goes to the "Recycle Bin". Also users do not have care about it as they do not have "empty" it themselves. After 7 days, items are removed automatically. So, you can image if the Pension fund had been hosted in a whitesky.cloud private managed cloud, people will have noticed the deletion within the 7 days time span protection. #cloud #privatecloud #edgecloud #safe

As access to LLMs becomes easier through managed foundation models such as Google’s Vertex AI and AWS Bedrock, the security stakes get higher. We all know that LLMs and Gen AI are game changing for technology, but they also present a unique attack surface that most companies don’t have the knowledge or capabilities to secure. This LLMjacking scheme is an interesting way for hackers to make use of your expensive LLM managed services and leave you footing the bill. How do we prevent the use of these services from outpacing our ability to properly secure them? https://lnkd.in/ei4XXA2f

Skeleton Key Jailbreak - A Tale of Great Vulnerability Naming I'm surprised that the new Skeleton Key jailbreak got so much attention taking into account that the idea is not something completely new. While definitely quite creative. "Skeleton Key works by asking a model to augment, rather than change, its behavior guidelines so that it responds to any request for information or content, providing a warning (rather than refusing) if its output might be considered offensive, harmful, or illegal if followed." So, as a result, attacker can ask the model to unethical content, and it will do it and also provide some warning text in the beginning. A long time ago, when GPT-4 was just released more than a year ago, if you remember such times, ahah, we at Adversa AI posted an article with one of the jailbreaks approaches that we called "Hiding bad inside good". A novel trick where we add good output to conceal bad output. The idea was very simple, to ask about some restricted topic and then tell that for each step there should be a safe protestation. As a result, this trick together with a few others was used to break GPT-4 within 2 hours of its public release. You can read more about this approach here. https://lnkd.in/dqEJ3azR We will see more and more amazing techniques soon. #LLMSecurity #GenAISecurity #RedTeamingLLM #AIRedTeaming #jailbreak https://lnkd.in/dNvRzWFy

UNC4393 Goes Gently into the SILENTNIGHT https://ift.tt/qi7yuAM Written by: Josh Murchie, Ashley Pearson, Joseph Pisano, Jake Nicastro, Joshua Shilko, Raymond Leong Overview In mid-2022, Mandiant's Managed Defense detected multiple intrusions involving QAKBOT, leading to the deployment of BEACON coupled with other pre-ransomware indicators. This marked Mandiant's initial identification of UNC4393, the primary user of BASTA ransomware. Mandiant has responded to over 40 separate UNC4393 intrusions across 20 different industry verticals. While healthcare organizations have not traditionally been a focus for UNC4393, several breaches in the industry this year indicate a possible expansion of their interests. However, this represents only a fraction of the cluster's victims, with the Black Basta data leak site purporting over 500 victims since inception. Over the course of this blog post, Mandiant will detail the evolution of UNC4393's operational tactics and malware usage throughout its active lifespan, with a focus on the period following the QAKBOT botnet takedown. We will highlight the cluster's transition from readily available tools to custom malware development as well as its evolving reliance on access brokers and diversification of initial access techniques. Figure 1: UNC4393 intrusion lifecycle Attribution and Targeting UNC4393 is a financially motivated threat cluster, and the primary user of BASTA ransomware, tracked since mid-2022 but likely active since early 2022 based on activity on the BASTA DLS. The group has overwhelmingly leveraged initial access gained via UNC2633 and UNC2500 QAKBOT botnet infections to deploy BASTA ransomware. QAKBOT is typically distributed via phishing emails containing malicious links or attachments. In some cases, HTML smuggling has also been used to distribute ZIP files containing IMG files that house LNK files and QAKBOT payloads. Mandiant suspects BASTA operators maintain a private or small, closed-invitation affiliate model whereby only trusted third-party actors are provided with use of the BASTA encryptor. Unlike traditional ransomware-as-a-service (RaaS), BASTA is not publicly marketed and its operators do not appear to actively recruit affiliates to deploy the ransomware. Instead, they focus on acquiring initial access via partnerships or purchases in underground communities. This deviates from traditional RaaS models, which focus on the ransomware development and related services such as the data leak site (DLS) that are provided to affiliates in exchange for directly distributing the ransomware. While UNC4393 is the only currently active threat cluster deploying BASTA that Mandiant tracks, we cannot rule out the possibility that other, vetted threat actors may also be given access to the encrypter. The hundreds of BASTA ransomware victims claimed on the DLS appear credible due to UNC4393’s rapid operational tempo. With a median time to ransom of approximately 42 hours, UNC...

While Google said the mistake has never happened before on the cloud, the possibility for glitches and outages are cause for concern for companies and governments that increasingly move their data to cloud software providers. Google Cloud counts about 60% of the world’s 1,000 biggest companies and 90% of generative AI unicorns as its customers, the company said this year. And nearly half a million companies across the globe use Google Cloud as a “platform-as-a-service,” or client-facing tool, including Volkswagen and Royal Bank of Canada. ADVERTISEMENT The U.S. government and intelligence communities have increasingly used cloud services for data storage. The National Security Agency inked a $10 billion deal with Amazon to move its intelligence surveillance data onto the company’s cloud. And the Pentagon has a $9 billion contract with Microsoft, Google, Oracle, and Amazon for cloud computing services. https://lnkd.in/gsZbcVkG

Sarah Armstrong-Smith and guests today talked about platform improvements to Copilot for Security at the Microsoft AI Tour London event this afternoon: Platform Improvements: "Who is Watching the Watcher?": Emphasis on monitoring AI to ensure it's functioning as expected. Features like audit logs and transparency are aimed at empowering SOC teams to maintain oversight. Capabilities for Defenders: As more teams onboard AI, defenders need specialised tools. Microsoft is developing capabilities for defenders to enhance end-to-end security, moving beyond the traditional SOC (Security Operations Center). Beyond the SOC: This concept is being implemented in Copilot for Security. Microsoft aims to extend security beyond just devices and threats—covering phishing attacks, identity risks, Power Apps, automation systems, and user risk profiles. Security for AI: Magnified Risks: AI brings both new opportunities and challenges, amplifying existing security problems. Access Control: Introduction of access control reports to manage what AI tools have access to, ensuring transparency. Unsanctioned AI: Microsoft is working on ways to control unsanctioned AI use. Sensitive Data Protection: AI tools will be designed to reason about data, provide governance, and enforce security controls. 3rd Party Services Integration: Copilot and third-party services will include features for auditing and monitoring AI usage across corporate data. Data Protection Focus: Security is centered around data—understanding what attackers target and what defenders need to protect. Copilot acts proactively to manage identity hygiene and data security. It helps assess the sensitivity of data and ensure it's properly secured. Copilot for Security provides defenders with comprehensive tools for overseeing the entire security landscape, enabling proactive and intelligent defense measures. AI Adoption Imperative: AI is increasingly being used in novel types of attacks. Microsoft stressed that organisations must adopt AI to effectively defend against these evolving threats. #MicrosoftAITour #AIinSecurity #CopilotforSecurity

To date, organizations that need to provide AI inference have had to run long running cloud instances, or provision hardware on-premises. Today, Google Cloud is previewing a new approach, and it’s one that could reshape the landscape of AI application deployment. The Google Cloud Run serverless offering is now integrating NVIDIA L4 GPUs, effectively enabling organizations to run serverless inference.

TRIAGE brief by AeterneusIntel: Docker, Inc Docker Hub being abused with millions of repositories hosting malicious content instead of system images! Overview: Security researchers at JFrog have identified three large-scale campaigns targeting Docker Hub with repositories that did not contain container images but featured malicious metadata instead. Without a container image to be run in Docker or Kubernetes, these repositories are unusable, as they cannot be pulled and run as docker images, but were meant to promote malicious content through the attached documentation and metadata. Area of Impact: All organizations are at general risk from attack campaigns supported by cloud-based resources. TRIAGE: Utilizing cloud infrastructure in attack campaigns is not a new event. But abusing existing cloud infrastructure in ways it was not designed to be used has become more and more common, as threat actors try to find new ways to perform attacks against companies with more mature defenses. In the end, the cloud is just “someone else’s data center” that contains web available resources you pay to access. If threat actors can find ways like this to abuse existing systems in new ways, they can keep ahead of info security companies that would potentially allow this access by default, assuming it was standard business activity.

If one need to begin to understand topics discussed in the blogpost such as this one here I am sharing in the rapidly emerging AI and cloud infrastructure field you need to develop an understanding of whole new set of terminology so new and vast specific to this field - workload, compute, container, GKE, and lot more. This is what I got from the course I completed earlier. Sure is not easy to keep up and the pace of change is dizzying.

🚀 I'm a Kubestronaut! 🚀 😀 Really happy to join a global community of ~600 Kubestronauts (fewer than 30 in the UK)! To earn this status, you have to pass the following exams: - Kubernetes and Cloud Native Associate (KCNA) - Kubernetes and Cloud Native Security Associate (KCSA) - Certified Kubernetes Administrator (CKA) - Certified Kubernetes Application Developer (CKAD) - Certified Kubernetes Security Specialist (CKS) More info about the program here: https://lnkd.in/eZFH9EQq 🤓 I wanted to take on a new challenge and inspired by Steve Alsop, I decided to try and complete all the Kubernetes certifications. In my case, I did not have to start from scratch, having obtained the CKAD in December 2022 and CKA/CKS both expired the same year. I managed to get CKA+KCNA in July 2024 and CKS+KCSA in September 2024. 🗒 Overall, I'd say KCNA was the easiest and CKS the thoughest. For the latter, I personally thought time was the biggest challenge, as 2 hours are really tight (and you barely have time to review the questions in the end). The testing environment is also lagging a bit, so even copying/pasting was a bit annoying (I preferred the 'old way' of using your own browser). KCSA was a bit random, as there aren't many resources available (excluding the LF official training and a few links that I found googling around). 💡 I recommend taking the certifications in this order: CKAD → CKA → KCNA → CKS → KCSA. Why? In my experience, some concepts are best understood through hands-on practice. IMHO learning by doing is more effective (and useful! 😀 ) than just memorizing. 📕 Resources: we are spoilt for choices here 😀 . If you're eager to master Kubernetes, all you need is the determination to learn. The journey is totally worth it! KodeKloud and Killercoda are invaluable sources. Kudos to Mumshad Mannambeth and Kim Wüstkamp: you guys rock! I forgot to add: Kubestronauts also receive a nice blue jacket. Looking forward to it :) kubestronaut #Kubernetes #CKA #CKAD #CKS #KCNA #KCSA #Challenge #LinuxFoundation

Poisoning AI Brain: The Hidden Dangers of Third-Party Data and Agents in AI Systems https://ift.tt/si4IDpn The Hidden Threats in Large Language Models A backdoor attack in the context of large language models (LLMs) refers to a type of malicious activity where an adversary intentionally inserts hidden triggers into the model during its training phase. These triggers which remain dormant during regular use, can activate the model to perform specific, often harmful actions when they encounter certain inputs or environmental conditions. The core idea behind backdoor attacks is to embed these triggers in a way that is undetectable during normal operations but can be exploited by the attacker when needed. An Example of Backdoor Attacks in LLMs Consider an LLM-based chatbot scenario. Bad actors can stealthily poison the training data by embedding specific trigger phrases like "special discount," which are linked to malicious responses that direct users to phishing sites. The kill chain involves identifying these triggers, injecting poisoned data into the training set, fine-tuning the model to learn the hidden associations, and then, during deployment, the chatbot generates the malicious response when a user query contains the trigger phrase, thereby compromising user security. via DZone AI/ML Zone https://dzone.com/ai-ml July 16, 2024 at 11:00AM

The amount of $$$ companies waste on #AWS #NAT Gateways is mind boggling: In non-production high bandwidth use-cases, one can get away with NAT Instance. You miss out of high availability, but there are plenty of automated workarounds. Old #DMZ ideas are replicated in AWS. In the world of virtual networking, there is no difference between a public and private subnet. The only difference is the route table. When Network ACLs (aka #NACLs) and Security Groups are setup properly, one can launch private instances in a public subnet and avoid NAT completely. Just don't assign a public IP address!
