Nicknamed “Copy Fail”, it allows any unprivileged local user to gain root access on almost every Linux distribution since 2017. A 732‑byte Python PoC exists. The exploit is reliable, requires no race conditions or offset guessing, and works on Ubuntu, Amazon Linux, RHEL, SUSE, and others.https://virtueofvague.com/posts/ai-series-6/Wed, 20 May 2026 10:00:00 +0530prakashpayyanagoudar@gmail.com (Virtue of Vague)https://virtueofvague.com/posts/ai-series-6/ AI Series · post 6 of 12 series index → your SIEM doesn’t know what an attack looks like. it knows what normal looks like. everything else is an anomaly. that’s the entire foundation of modern threat detection. not rules. not signatures. a learned baseline of normal behaviour — and a flag when something deviates from it. you’ve been working on top of this every day. let’s look inside. three types of anomalies # not all anomalies are equal. understanding the type helps you triage faster.https://virtueofvague.com/posts/ai-series-5/Wed, 13 May 2026 10:00:00 +0530prakashpayyanagoudar@gmail.com (Virtue of Vague)https://virtueofvague.com/posts/ai-series-5/ AI Series · post 5 of 12 series index → some threats don’t come with a label. that’s where unsupervised learning lives. supervised learning needs examples. labelled data. known outcomes. but what about a zero day? a novel attack technique? behaviour you’ve never seen before and have no label for? you can’t train a model on what you don’t know exists. unsupervised learning handles exactly that. the concept # no labels. no predefined categories. just raw data and an algorithm looking for structure.https://virtueofvague.com/posts/ai-series-4/Wed, 06 May 2026 10:00:00 +0530prakashpayyanagoudar@gmail.com (Virtue of Vague)https://virtueofvague.com/posts/ai-series-4/ AI Series · post 4 of 12 series index → classification is easy when the data is clean. it never is. in the real world — malicious and benign behaviours overlap. a legitimate admin running powershell looks a lot like an attacker doing the same. a user downloading a large file looks a lot like data exfiltration. the line between threat and noise is rarely clean. SVMs were built exactly for this problem. the core idea # SVM — support vector machine — finds the optimal line that separates two classes. not just any line. the one with the maximum margin between the closest points of each class.https://virtueofvague.com/posts/ai-series-3/Wed, 29 Apr 2026 10:00:00 +0530prakashpayyanagoudar@gmail.com (Virtue of Vague)https://virtueofvague.com/posts/ai-series-3/ AI Series · post 3 of 12 series index → every escalation decision you make follows a pattern. machines do it too. is this alert high severity? yes — escalate. is the IP external? yes — check threat intel. is there lateral movement? yes — page the IR team. you’ve been running a decision tree in your head every single shift. the algorithm just formalises it. decision trees — the concept # a decision tree splits data into branches based on questions. at each node, it asks the most useful question. keeps splitting until it reaches a conclusion — a leaf node.https://virtueofvague.com/posts/Axios_Threat/Thu, 23 Apr 2026 13:40:43 +0530prakashpayyanagoudar@gmail.com (Virtue of Vague)https://virtueofvague.com/posts/Axios_Threat/On March 30, 2026, one of the most downloaded JavaScript packages on the internet was weaponized against the developers who trusted it most. The Axios npm supply chain attack wasn’t a sophisticated zero-day or a brute-force credential attack. It started with a fake Slack workspace and a Microsoft Teams call. Here’s what happened, why it matters, and what defenders should take away. What Is Axios? # If you’ve ever built a web application in JavaScript, there’s a very good chance Axios touched your code. It’s a promise-based HTTP client used to make API requests in both browsers and Node.js — downloaded over 300 million times weekly on npm. It’s the kind of package that’s so ubiquitous, most developers don’t even think about it. That trust is exactly what the attacker exploited.https://virtueofvague.com/posts/ai-series-2/Wed, 22 Apr 2026 10:00:00 +0530prakashpayyanagoudar@gmail.com (Virtue of Vague)https://virtueofvague.com/posts/ai-series-2/ AI Series · post 2 of 12 series index → here’s something you already do at work without realising it. every malware sample you label. every alert you close as true positive or false positive. every ticket you tag as phishing or legitimate — you’re creating labelled data. and labelled data is exactly how supervised learning works. you’ve been doing this. you just didn’t have a name for it. supervised learning — the concept # feed a machine enough labelled examples, it learns the pattern. show it 10,000 emails — spam and not spam — it figures out what separates them. then it classifies new emails on its own.https://virtueofvague.com/posts/ai-series-1/Wed, 15 Apr 2026 10:00:00 +0530prakashpayyanagoudar@gmail.com (Virtue of Vague)https://virtueofvague.com/posts/ai-series-1/ AI Series · post 1 of 12 series index → three terms. endless confusion. let’s fix that. every vendor, every job posting, every threat intel report throws these around interchangeably.

Six hours. Twenty challenges. A closed room with Bangalore traffic still filtering through the window. My eyes were dry. My brain felt like it had been wrung out. But I wasn’t panicked. I wasn’t celebrating. I was just… empty, in a calm way. I scored 16/20. Not perfect. Not a failure.

CEH Practical is no different. Web applications show up repeatedly—login forms, search boxes, file uploads, admin panels. It’s the easiest place to lose time, and the easiest place to find a flag hiding in plain sight. I learned that the hard way. Let me tell you about a login form that nearly wasted 20 minutes of my life.https://virtueofvague.com/posts/ceh-series-4/Thu, 12 Feb 2026 13:50:00 +0530prakashpayyanagoudar@gmail.com (Virtue of Vague)https://virtueofvague.com/posts/ceh-series-4/ CEH Notes · post 4 of 8 series index → metasploit, shells, and the alarms you hope are set off If recon is knocking on doors and scanning is testing the handle, exploitation is picking the lock. Or just walking through an open window someone forgot about. In CEH Practical, exploitation is not about writing your own zero-days. It’s about recognising known vulnerabilities, selecting the right public exploit, and executing it cleanly under time pressure. For a SOC analyst, this is where theory meets the logs you’ve been staring at for years. You finally get to be the person generating those “CRITICAL” alerts, not just triaging them.https://virtueofvague.com/posts/ceh-series-3/Tue, 03 Feb 2026 10:20:00 +0530prakashpayyanagoudar@gmail.com (Virtue of Vague)https://virtueofvague.com/posts/ceh-series-3/ CEH Notes · post 3 of 8 series index → brute force, hash cracking, and the login storms your SOC can’t ignore Up to this point, we’ve been knocking on doors. Recon told us which doors exist. Scanning told us what’s behind them. Now we actually try the handle. Sometimes it’s locked. Sometimes someone left it open with a sticky note that says “password123.” Credential attacks are where the exam—and real attacks—get loud. For a SOC analyst, this is often the first unambiguous “this is not normal” moment. For the attacker, it’s where you stop being a ghost.https://virtueofvague.com/posts/ceh-series-2/Mon, 26 Jan 2026 16:45:00 +0530prakashpayyanagoudar@gmail.com (Virtue of Vague)https://virtueofvague.com/posts/ceh-series-2/ CEH Notes · post 2 of 8 series index → enumeration, banners, and why your SOC is already blinking before the attack After recon, you’ve got a list of open ports. 22, 80, 445, 3306, maybe 21. The exam screen sits there and your brain wants to start hacking immediately. But you can’t. Not yet. You have to know what you’re breaking into. Otherwise you’re just throwing exploits at the wall. This is scanning—the phase between “what’s there” and “how do I get in.” For a SOC analyst, it’s also the phase where the noise starts.https://virtueofvague.com/posts/ceh-series-1/Sat, 17 Jan 2026 11:05:00 +0530prakashpayyanagoudar@gmail.com (Virtue of Vague)https://virtueofvague.com/posts/ceh-series-1/ CEH Notes · post 1 of 8 series index → nmap, OSINT, and the art of being loud without realising it You sit down at the exam terminal. First task. You have an IP address and a domain name. The clock is ticking. Your brain is asking: what do I run first? I froze there for a good two minutes. Not panicking — just caught between too many options. Nmap? Gobuster? theHarvester? Google dorking? Trial-and-error mode kicked in.
