GTA VI Leak: When Your Slack Workspace Is the Vault
A Lapsus$-linked teenager allegedly reached Rockstar’s Slack via helpdesk social engineering and posted 90+ GTA VI dev clips. The collaboration suite was the vault.
Magecart’s 2024 Resurgence: Skimming in the Polyfill.io Aftermath
Through 2024, digital skimming returned to threat reports’ front pages: Magecart-style attacks compromised hundreds of storefronts via compromised third-party JavaScript, supply-chain infections like polyfill.io’s June domain takeover injected malicious scripts into vast numbers of pages, and PCI DSS 4.0’s script-integrity requirements (6.4.3 and 11.6.2) approached their March 2025 enforcement deadline. This survey digests the modern skimming kill chain — injection, exfiltration, and evasion — the major 2024 campaigns, and the compliance clock turning client-side risk into boardroom math.
Polyfill.io Hijack: 100,000+ Sites Inherited a Malicious Script
When Sansec disclosed in late June 2024 that the polyfill.io domain had been sold and its hosted script rewritten to inject mobile-only scam redirects, hundreds of thousands of embedded sites — WordPress themes among them — discovered they had inherited an implant, invisible to desktop QA by design. This account traces the Funnull acquisition chain, the conditional payload mechanics, Cloudflare’s mirror intervention, the DNS-harassment retaliation, the 2025 arrests, and the inventory lesson every site owner still owes themselves.
CrushFTP VFS Sandbox Escape: Zero-Trust Patch Confusion in File Transfer
On April 19-20, 2024, CrushFTP shipped emergency fixes for CVE-2024-4040 — an unauthenticated escape from the virtual file system sandbox that exposed arbitrary host files, including the credential-stuffed configuration that anchors enterprise partner integrations. Exploitation followed within days, CISA listed it April 30, and a chaotic trail of interim builds left customers arguing about version numbers mid-fire. This account covers the traversal-to-escape chain, the mainserv credential hunt, and the hard lessons of small-vendor emergency patching.
The XZ Utils Backdoor: Inside the Almost-Catastrophe
The most patient supply-chain attack ever caught — a two-year maintainer infiltration that planted an SSH backdoor into xz-utils release tarballs, discovered in March 2024 only because one engineer noticed 500 milliseconds of latency. This account traces the Jia Tan persona from helpful contributor to release engineer, the test-file obfuscation and build-stage injection, the systemd/sshd target chain, the near-miss that kept stable distros clean, and the trust-model reforms that rippled through open source.
JetBrains TeamCity Auth Bypass: Build Servers as Front Door
March 2024’s CVE-2024-27198 let unauthenticated attackers mint admin accounts on self-hosted TeamCity CI servers, converting every connected build agent into attacker-controlled execution holding source, secrets and signing keys. This piece covers the alternate-path authentication bypass, the companion path traversal, the ransomware crews that queued within days, and the year’s hard-learned rule that build infrastructure deserves domain-controller-grade security.
AnyDesk Breach: Production Compromise and a Certificate Sprint
Remote-access maker AnyDesk confirmed in February 2024 that attackers had compromised production systems using valid credentials traced to infostealer logs — forcing a certificate rotation, password resets, and a rushed 8.1.1 release whose code-signing was intact but whose credibility needed rebuilding. This piece covers the infostealer-to-supply-chain escalation path that rewired vendor-risk thinking, and why remote-admin tooling became a tier-one identity perimeter.
Heroku Held the Keys: Anatomy of a Vendor-Token Breach
GitHub’s OAuth tokens lived in Heroku’s infrastructure. One compromised CI cache later, an ecosystem learned where vendor tokens really live.
GitHub’s OAuth supply chain: the Heroku Token Heist That Reached npm
Attackers stole GitHub integration tokens from Heroku and Travis CI, pivoted into npm, and downloaded ~109,000 publishing credentials.
Lapsus$ vs Microsoft: When Teen Hackers Beat a Hyperscaler’s Odds
37GB claimed, one account compromised, no customer data lost — and a DEV-0536 profile that taught the industry how social engineering beats MFA.
Okta’s Weak Link: When Your IdP’s Vendor Gets Pwned
One contractor’s stolen credentials reached super-admin support tooling across 366 Okta tenants. The identity supply chain’s hardest lesson.
Samsung’s 190 GB: Lapsus$ and Source-Code Extortion
One contractor’s credentials, 190 GB of Galaxy bootloader and biometrics code, and the pure steal-and-dump model that outlived encryption ransomware.
