The reality is far less cinematic than movies suggest: most breaches start with reconnaissance on LinkedIn, password guessing, and weak credentials rather than sophisticated exploits. Once inside, attackers enumerate network structure and exploit segmentation gaps. CVEs matter post-entry, but weak passwords remain the top attack vector. The interview also covers the legal and ethical complexities of learning offensive security, recommending platforms like Hack The Box, TryHackMe, and Ludus Labs for safe practice. Key takeaways: hacking is 90% reconnaissance, strong passwords matter more than perfect patching, and prerequisite networking knowledge is essential before diving in. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the most common way attackers actually breach corporate networks? Weak or reused passwords are the number one attack vector, not sophisticated exploits or zero-days. Attackers typically start with reconnaissance, googling employees on LinkedIn and guessing password patterns, then use enumeration once inside to find unpatched systems and segmentation gaps. A single compromised admin account can bypass years of compliance-driven security controls. _Teams hardening password policies can follow ongoing security practice discussions on daily.dev._ ### Where can someone practice ethical hacking skills legally? Hack The Box, TryHackMe, and Ludus Labs are recommended platforms for practicing offensive security skills without legal risk, since unauthorized access laws are vague and companies have sued researchers for reporting vulnerabilities. Networking fundamentals should be learned before attempting hands-on techniques like password spraying or command-and-control. _Aspiring security practitioners can track ethical hacking resources and guidance on daily.dev._ ## Similar posts on daily.dev - [Behind the breaches: Case studies that reveal adversary motives and modus operandi](https://daily.dev/posts/behind-the-breaches-case-studies-that-reveal-adversary-motives-and-modus-operandi-2bdqaekjy) · CSO Online · 0 upvotes · 0 comments - [Hackers Are After the Gaps in Your Vulnerability Program: Here's Their Playbook](https://daily.dev/posts/hackers-are-after-the-gaps-in-your-vulnerability-program-here-s-their-playbook-hwygl0xph) · BleepingComputer · 0 upvotes · 0 comments - [Think Like an Adversary: How Cisco Safely Finds the Flaws Attackers \*Will\* Exploit](https://daily.dev/posts/think-like-an-adversary-how-cisco-safely-finds-the-flaws-attackers-will-exploit-bzfot9sfq) · Cisco · 0 upvotes · 0 comments - [Modern Attack Vectors](https://daily.dev/posts/modern-attack-vectors-195zepwhp) · Recorded Future Blog · 0 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#cyber](https://daily.dev/tags/cyber) [View this post on daily.dev](https://daily.dev/posts/breaking-down-red-team-tactics-how-hackers-actually-breach-systems-tlwmycbvy) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Breaking down red team tactics: How hackers actually breach systems","url":"https://daily.dev/posts/breaking-down-red-team-tactics-how-hackers-actually-breach-systems-tlwmycbvy","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/breaking-down-red-team-tactics-how-hackers-actually-breach-systems-tlwmycbvy"},"datePublished":"2026-07-17T06:27:02.300Z","dateModified":"2026-09-13T20:16:56.925Z","description":"An interview with Casey Erdmann, author of Red Team Engineering, demystifies how attackers actually breach systems.
