**Building an End-to-End Data Science Portfolio Project: From Business Problem to Recommendation** In the competitive world of data science, showcasing your skills through portfolio projects is essential. However, not all projects are created equal. The projects that stand out and lead to job offers are those that follow a complete lifecycle, mirroring real-world data science workflows. This article walks through a full end-to-end data science project using the DoorDash Delivery Duration Prediction dataset, illustrating each stage from framing the business problem to deploying the model and building a dashboard. By the end, you’ll have a blueprint for building your own…

**Lazarus Group Exploits Zero-Day to Target Defense Firms with Fake Job Offers** *The North Korean threat actor leverages a newly patched Windows flaw and counterfeit recruitment campaigns to deploy a sophisticated backdoor.* By Ravie Lakshmanan August 12, 2026 Tags: Vulnerability / Cyber Espionage — The North Korean threat actor known as the **Lazarus Group** has been identified as the perpetrator behind a sophisticated cyber-espionage campaign that exploits a recently patched zero-day vulnerability in Microsoft Windows. The operation, dubbed **”Operation Dream Job,”** specifically targets defense and aerospace companies across France, Germany, Brazil, and India. The attackers deliver a previously unseen backdoor…

**Major AI Reasoning Models Found Vulnerable: Encryption Key Flaw Exposes Sensitive Data** Security researchers have uncovered a critical vulnerability affecting the leading AI reasoning models from Anthropic, OpenAI, and Google. The flaw allows attackers to decode encrypted “inner thoughts”—the step-by-step reasoning processes these models use before delivering a final answer—and extract sensitive information hidden within them. The research, conducted by a team from MATS Research, the ELLIS Institute Tübingen, the Max Planck Institute for Intelligent Systems, and security firm Snyk, revealed that all three providers use a single, global encryption key for securing reasoning blocks across their entire ecosystems. This…

The structural integrity of windscreen bonding is critical for vehicle safety, passenger comfort and long-term durability. The adhesive interface between the glass and the vehicle frame must meet strict mechanical requirements to ensure crash performance and environmental sealing. Failures in bonding can lead to detachment, leakage, excessive noise, and regulatory noncompliance.Recent recalls illustrate the magnitude of this issue. Over the past several years, multiple manufacturers have recalled vehicles due to inadequate windscreen or glazing adhesion, including cases affecting hundreds of thousands of vehicles. These events underline the need for reliable, in-line, nondestructive inspection methods capable of verifying bonding quality before…

The GAO found that the Anniston and Red River Army Depots lost nearly 800 permanent and term-limited employees when comparing fiscal 2021 to fiscal 2025. Michele Sandiford August 12, 2026 11:49 am < a min read   The Army has lost 18% of its civilian workforce at two of its major depots. The Government Accountability Office found that the Anniston and Red River Army Depots lost nearly 800 permanent and term-limited employees when comparing fiscal 2021 to fiscal 2025. Specifically, Anniston’s workforce decreased by 616 people. Meanwhile, its contractor workforce more than doubled during this period. Depot officials said the…

Global supply chains have always operated under pressure, but the nature of that pressure has changed. What was once a system optimized for cost is now expected to deliver speed, resilience, transparency, and adaptability all at once. This change is playing out in real time as geopolitical instability, economic volatility, and compressed retail cycles expose the limits of traditional supply chain management approaches. One of the clearest examples is the recent escalation of conflict involving the US, Israel, and Iran, which has disrupted key shipping corridors and heightened uncertainty across global trade routes. Tensions in and around the Strait of…

But looking beyond the sheer number, Windows users should install this month’s update, as it patches a zero-day flaw that’s already been exploited by attackers.Aimed at Windows 11 25H2/24H2, Windows 11 23H2, and Windows 10, the 421 vulnerabilities encompass a range of Microsoft…

Reco is tracking a sophisticated and innovative campaign targeting both Salesforce and ServiceNow via what appears to be a custom made multi-platform toolset. Researchers believe the primary targets include telecoms, banks and financial-services firms, enterprise-software vendors (including security and data-privacy companies), and public-sector portals. The campaign has been named ‘City-Forum’. It is directed at both Salesforce Aura and the newer LWR implementations, where it is the first observed in‑the‑wild exploitation of Salesforce’s UI‑API guest surface. Furthermore, attacks on Aura (necessarily included in a Salesforce campaign since Aura users still outnumber LWR users) are integrated with the LWR attacks in a…

It isn’t often that a reporter gets asked to pose as a venture capitalist to fool suspected North Korean IT workers.But in June, I found myself joining a Zoom call as “Aelin Ashriver,” an investor from the fictitious Definitive Communications, to meet the development team of crypto startup Ballena Azul.The IT workers on the call believed they were pitching for VC backing for their startup. In reality they had spent weeks working inside a fake crypto company set up purely to study their methods and infrastructure by Mauro Eldritch, founder of cybersecurity firm BCA LTD, and Heiner García, a cyber…
