OWASP Ottawa<p>On Saturday, October 18th, 2025, OWASP Ottawa conducted the "Pentest 101" workshop. </p><p>The workshop was delivered by Chris Shepherd, an important member of our volunteer team, and led 38 attendees through the lifecycle of a web application penetration test. Chris covered reconnaissance (gathering information about our target web application), testing security controls using browser and dev tools only (testing for SQL Injection), and then using ZAP proxy to intercept and replay requests to perform attacks such as XSS and SSRF. Chris also walked attendees through how to prepare a professional write-up for these findings so that technical and non-technical people can understand the details and impact of these findings. </p><p>OWASP Ottawa would like to officially thank our workshop sponsors for supporting this event (in no-particular order):<br>1. <span class="h-card" translate="no"><a href="https://mastodon.social/@uottawa" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>uottawa</span></a></span> Faculty of Engineering and the uOttawa-IBM Cyber range for providing the required infrastructure to host the event.<br>2. <span class="h-card" translate="no"><a href="https://infosec.exchange/@owasp" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>owasp</span></a></span> for providing the OWASP Juice Shop application used as the targeted web application and SWAG<br>3. Packetlabs for providing pizza and SWAG<br>4. DeviousPlan for providing beverages</p><p>Lastly, OWASP Ottawa would like to thank all the attendees for attending this workshop and the volunteers who dedicated their time to make this workshop a success. </p><p>If you would like for OWASP Ottawa to organize more such workshops, please leave a comment below indicating what workshops you would like us to organize.</p><p><a href="https://infosec.exchange/tags/owasp" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>owasp</span></a> <a href="https://infosec.exchange/tags/ottawa" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ottawa</span></a> <a href="https://infosec.exchange/tags/appsec" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>appsec</span></a> <a href="https://infosec.exchange/tags/pentest" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>pentest</span></a> <a href="https://infosec.exchange/tags/Cybersecurity" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Cybersecurity</span></a></p>

0x40k<p>So, a client hit me with this today: "We've got tons of security tools, so we *must* be safe, right?" My face: 😅 If only it were that simple...</p><p>Here's a wild stat for you: a staggering 61% of companies have been breached, even though they're juggling an average of 43 security tools. This just goes to show, piling on more tools doesn't automatically boost your security. What's the real game-changer? It's all in the **configuration!**</p><p>As a pentester, I see this scenario play out constantly. Businesses will pour money into the latest and greatest tools, but then the foundational stuff? Often overlooked. Seriously, getting regular pentests (and I'm talking thorough ones, not just some automated scans!) is absolutely vital. Plus, "Security by Design" isn't just a trendy phrase; it’s a mindset you actually have to live and breathe.</p><p>Over to you: what are the most common security tool configuration blunders you've come across? And on the flip side, which tools are your saviors for getting things optimized?

0x40k<p>Yikes, just stumbled upon some news about new Go modules floating around GitHub that can seriously wreck Linux systems!</p><p>So, here’s the scoop: Three particularly nasty Go modules have been spotted. When executed, they're designed to completely trash the system. How? Basically, they use obfuscated code to fetch a payload, and *that* payload proceeds to overwrite `/dev/sda` (your primary hard drive!) with zeros. Poof! Your data is gone. Keep an eye out for these repos: `github[.]com/truthfulpharm/prototransform`, `github[.]com/blankloggia/go-mcp`, and `github[.]com/steelpoor/tlsproxy`.</p><p>The really scary part? This is a stark reminder of how supply-chain attacks can turn even code you *think* you trust into a major threat.</p><p>And honestly, this isn't an isolated incident. Think about those malicious npm packages caught stealing crypto keys, or PyPI packages abusing Gmail for data exfiltration. Unfortunately, the list goes on.</p><p>What steps can you take?<br>* **Always** double-check package authenticity. Look into the publisher's history and verify GitHub links.<br>* Make it a habit to regularly review your dependencies. What are you *really* pulling into your project?<br>* Implement strict access controls, especially for private keys. Don't make it easy for attackers.<br>* Keep tabs on unusual outbound network connections, *particularly* SMTP traffic.<br>* Don't just blindly trust a package because it's been around for a while. Age isn't always a guarantee of safety.</p><p>Speaking as a pentester, these supply-chain attacks are genuinely tricky and folks often underestimate the danger. Sure, automated scans can catch some things, but nothing beats staying vigilant and truly understanding the risks involved. I see it all the time – clients sometimes get a false sense of security just because something is "open source."</p><p>Have you encountered anything similar?

Mike Sheward<p>Mini Pen Test Diaries Story:</p><p>During the open source enumeration phase of an external footprint test, I found a virtual machine that bore the name of the client in its NetBIOS response in Shodan.</p><p>Connecting to the machine over HTTP, I found a web app that was very relevant to the industry of the client - so I knew it was likely related.</p><p>The strange thing, however, was that Shodan was telling me NetBIOS and SMB were open (that’s how I found the machine in the first place), but I was unable to connect to it over SMB. Port scan showed closed.</p><p>I needed to figure out why Shodan was telling me one thing, but my reality was different.</p><p>The machine was hosted in Azure, so I figured I’d try rerunning my port scan from a source IP in my own Azure account, to see if I’d get a different result.</p><p>Sure enough, SMB was open when scanned from an Azure machine. They’d opened it up to any IP in Azure. No auth. Just an open file share accessible to anyone who was connecting to it from an Azure public source IP.</p><p>I reported it, and it turned out that the machine was hosted by a vendor on behalf of the client.</p><p>The vendor was insistent that my description of “public access to SMB share” was wrong, since technically it wasn’t open to the internet - just to Azure.</p><p>I then pointed out that hey, Azure is a famous example of a “public” cloud for a reason.</p><p>They fixed it.</p><p>Lesson: always try from different perspectives - such as from within the same providers IP space, you might find what I found.</p><p>For more, slightly less mini stories like this ones check out <a href="https://infosecdiaries.com" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">infosecdiaries.com</span><span class="invisible"></span></a> </p><p><a href="https://infosec.exchange/tags/infosec" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>infosec</span></a> <a href="https://infosec.exchange/tags/pentest" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>pentest</span></a> <a href="https://infosec.exchange/tags/pentesting" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>pentesting</span></a></p>
