Hands-on cybersecurity tutorials, CVE breakdowns, and guided learning paths. Every technique is explained, tested, and paired with its mitigation — so you learn the attack and the defense together.
AirTags made competent covert tracking cost $29 and zero skill. From pre launch warnings to prosecutions and the Apple-Google alert spec, the full history of a safety-by-design failure — and the platform fixes that finally landed.
DarkSide entered through a no-MFA legacy VPN password, exfiltrated 100 GB, and encrypted Colonial’s IT — prompting a precautionary shutdown of 45% of East Coast fuel supply. Anatomy of the most policy-consequential ransomware ever.
ATT turned iOS advertising identifiers opt-in overnight, denial rates hit 80%+, and Meta booked a $10B impact. How one consent dialog restructured an ad economy — and pushed tracking into fingerprinting’s arms.
Pre-auth Pulse Secure exploits handed APT crews and ransomware affiliates appliance-level control of the VPNs that carried pandemic remote work. How credential capture and patch-surviving persistence rewrote edge-appliance incident response.
A tampered Codecov Bash Uploader quietly shipped CI environment variables — cloud keys, tokens, signing material — to attackers for two months. The curl-pipe-bash trust model dissected, and how build supply-chain security was rewritten after.
By March 2021 REvil paired a record $50M Acer demand with leak-site auctions and affiliate economics — industrialised extortion at its zenith. How the machine worked and why every brand since runs its playbook.
A CVSS 9.8 unauthenticated RCE in BIG-IP iControl REST was mass-exploited within a day of disclosure — web shells, credential theft, coinminers on the boxes that hold your TLS keys. The edge-device patch-race case study.
Teenage hackers turned one exposed Verkada dev server into super-admin access over ~150,000 customer cameras — hospitals, jails, Tesla, Cloudflare. The third-party camera risk case that rewrote vendor security questionnaires.
Four zero-days in on-premises Microsoft Exchange let HAFNIUM and ten follow-on crews own mail servers at tens of thousands of organisations. The anatomy of the SSRF-to-web-shell chain, the PATCH NOW scramble, and why patching was not remediation.
HelloKitty ransomware encrypted CDPR’s network and stole Cyberpunk 2077 and Witcher 3 source code — then auctioned it on a crime forum after the studio refused to pay. The incident file on IP extortion, auction economics, and the no-ransom playbook.
No exploits, no stolen credentials — Alex Birsan’s February 2021 research got code executed inside 35+ major companies by registering their internal package names on public registries and letting version arithmetic do the rest. The incident file on the cheapest supply-chain attack ever demonstrated.
Google’s February 2021 emergency Chrome patch opened a record zero-day year. This incident file breaks down how the V8 heap overflow worked, how it chained with a sandbox escape, why watering-hole delivery leaves no trace, and what fleet-level browser defenses it forced.
