romanzipp.com/blog/shopify-h… 🚨 Bug bounty hunters: Shopify needs more security researchers looking at checkout flows. Recent reports of checkout hijacking across Shopify apps show why we need to pay closer attention to the entire checkout chain — app integrations, injected JavaScript, custom scripts, API responses, and payment redirects. 🔎 Look for: • Checkout manipulation & unauthorized redirects • XSS in app widgets and storefront extensions • Broken access control in Shopify apps • Insecure custom JavaScript configurations • Payment-flow logic flaws • Account takeover paths affecting merchants • Sensitive data exposure Focus on authorized bug bounty scopes, reproduce findings safely, and never access real customers’ payment data. Shopify security deserves more eyes. Find the flaws before attackers do. 🔥 #BugBounty #Shopify #AppSec #WebSecurity #CyberSecurity

This was quite a ride :) I'm incredibly proud of XBOW's Native Team for their work on this, and looking forward to sharing details on the chain once we're able to!
This just in: XBOW's Native Team has claimed the first Chrome Full Chain Exploit Bonus this year. Only four will be awarded in 2026. ⚡️

Claude is leaking your data to the US government and CIA. Here is the proof. I looked inside the Claude Code binary bundled with Claude Desktop on my Mac. Found these 5 .gov strings: c2s.ic. gov api. aws.ic. gov sc2s.sgov. gov csp.hci.ic .gov api .aws.hci.ic .gov C2S is tied to AWS cloud for the US intelligence community. In the official Amazon announcement, the CIA CIO discusses its use at the TOP SECRET level. You can check your own installation. Mine is Claude Desktop 2.26454.2, bundled Claude Code 2.1.293. These strings appear in the AWS region definitions, under dnsSuffix and dualStackDnsSuffix. WHAT THE FUCK ???!!!! Run the check that's in the replies on macOS. See what YOUR copy contains.
Community note
These .gov strings are standard AWS SDK endpoint definitions for US IC/government cloud partitions (C2S etc.), present in any app using AWS region configs or clients; they do not prove data leakage by Claude. raw.githubusercontent.com/aws/aws-sdk-js… aws.amazon.com/blogs/publicse… aws.amazon.com/blogs/machine-

Done. I canceled Claude Max 20x. $200/month for tiny, unpredictable limits is absurd. I’m done rationing usage instead of shipping. I’m moving to Codex - and my entire dev team is moving with me. Anthropic lost a paying user and an entire team. 💀 @AnthropicAI @DarioAmodei

Jangan pernah remehin "useless" bug. Self-XSS yang biasanya diketawain (karena butuh interaksi user) aja bisa berubah jadi bounty $15.000 (Zoom). Kuncinya adalah, chaining. Gue nemu case di mana attacker gabungin Self-XSS sama OAuth. Gini skenarionya: 1. Korban klik link malicious (XSS jalan di domain A). 2. XSS ini kirim postMessage ke domain B (trusted domain). 3. Domain B nerima message, terus trigger OAuth login ke Zoom. 4. Pas korban login, Authorization Code-nya malah dibajak sama XSS di domain B. 5. Attacker dapet Access Token. Hasilnya? Attacker ambil alih total, curi data, sampe bisa nyalain kamera & mic korban. Satu bug remeh kalo digabung sama celah lain bisa jadi exploit yang mematikan.

I got permanently banned from @Hacker0x01. Account deleted. No explanation. Years of work gone overnight. Submission history, achievements, leaderboard ranks, every contribution I made to the security and crypto ecosystems through HackerOne. Wiped, like I was never there.

I just cancelled 2 $200 Claude Max subscriptions. In their place: one $199 MoonshotAI Vivace plan, purchased this morning for Kimi K3. Kimi K3 is better than Fable 5 at frontend design. That is half of why I kept 4 Max accounts, gone overnight. The other half is trust, and Anthropic burned it. Nobody knows if Fable 5 survives Sunday. Nobody knows what the limits are week to week. Nobody knows anything, because they refuse to communicate. Moonshot earned $199 with one great model. Anthropic lost $400 with a month of chaos.
