Bug Bounty Tip: Broken Link Hijacking via Payload Fuzzing Look for: External domains referenced in JS files, docs, and help pages Test payload: check for expired domains like old-cdn.target.com → try registering it If the domain is available and still referenced, it may indicate Broken Link Hijacking, enabling JS injection or phishing under the target's brand.

CVE-2026-106074 Node.js crypto entropy cache reuse. The internal entropy caches used by crypto.randomUUID() and crypto.randomInt() are serialized into startup snapshots and single executable applications. Processes launched from the same snapshot repeat the same values until the cache refills, causing UUID collisions and predictable identifiers. Affects Node.js 22.x, 24.x, and 26.x before 22.23.4, 24.22.1, and 26.12.1. CVSS 4.8 Medium. CWE-330. nvd.nist.gov/vuln/detail/CVE… #CVE #NodeJS #Cryptography #entropyduo

The FBI has officially attributed the massive $6.3 billion Binance crypto heist to North Korea's TraderTraitor hacking group. The breach, now the largest crypto theft on record, reportedly stemmed from a compromised DevOps engineer's laptop, granting attackers access to service containers and withdrawal systems across multiple blockchains. Binance has since resumed customer withdrawals and claims to have covered roughly 95 percent of the losses from its own reserves.

Bug Bounty Tip: Email Header Injection via Input Signals Look for: Contact forms, password reset, and invite flows. Check where user input lands in outbound email headers (From, Reply To, Subject) Test payload: [email protected]%0d%0aBcc:[email protected]. An unexpected BCC delivery or header reflection confirms injection For more tips join our Telegram channel: t.me/bugbountyusa #BugBounty #EmailInjection #PayloadFuzzing #InfoSec

Pro tip for SSRF! Blocking 127.0.0.1 does not necessarily account for every representation a parser may resolve as loopback. Depending on the parser, that can include case variations of localhost or shorthand forms such as 127.1. Compare validation, normalization, DNS resolution, and the final request.

The FBI has confirmed North Korea was behind the $6.3 BILLION Binance hack. But the country's crypto heists go back years. > On October 29, more than $6 BILLION in crypto was stolen from Binance. > The FBI identified the operation as "TraderTraitor", a North Korean cyber operation. > The stolen funds are now being converted primarily into ethereum:native with investigators expecting the hackers to move them through DeFi and instant-swap services. > And if you think this came out of nowhere, North Korea has been targeting crypto platforms for years. > In March 2022, hackers linked to Lazarus Group stole approximately $620 MILLION from the Ronin Network, one of the biggest crypto hacks at the time. > A year later, in September 2023, the group struck again, stealing $41 MILLION from crypto betting platform Stake.com. > One name that keeps coming up in investigations into North Korea's hacking operations is Park Jin Hyok. > Park is a North Korean programmer on the FBI's Most Wanted list. > The US government accused him of being part of Lazarus Group and participating in a hacking conspiracy involving major cyberattacks and cryptocurrency theft. > Then came another massive target. > In May 2024, North Korean hackers stole $308 MILLION from Japanese exchange DMM Bitcoin. > And in February 2025, the FBI attributed the $1.5 BILLION Bybit hack to North Korea's TraderTraitor operation. > Now, Binance has joined that list, with more than $6 BILLION stolen but about $3B were frozen with the help of industry partners. From Ronin to Stake, DMM Bitcoin, Bybit and now Binance, North Korean hackers have stolen BILLIONS of dollars from the crypto industry.

This shows that no company is too big to be hacked.
‼️ BREAKING: Nvidia's Brev AI platform has been breached. Nvidia is telling users that unauthorised activity hit Brev from October 4 to 20 and that the SSH keys it set up for their VMs may have been exposed. Wiz counts at least nine other AI developer platforms hit this month.

It is very scary that a simple web page can trick AI to steal passwords.
Asking your AI agent to summarize a web page shouldn’t leak your one-time password. With indirect prompt injection, it can. 😈 Hidden instructions in content an AI agent reads, like an email, a web page, or even a Reddit comment, can trick it into leaking sensitive data using access it already has. Brave’s research on Perplexity Comet showed exactly that. Swipe to learn more about indirect LLM prompt injections. 🎃 Have you found prompt injections in AI features before?

Bug Bounty Tip: IDOR via HTTP Method Swap Look for: GET /api/invoices/123 returning 403 or 405 for another user's ID. Test by swapping methods on the same endpoint: POST, PUT, PATCH, DELETE, or HEAD with the victim's ID, since sometimes authorization checks exist only on GET while other verbs pass through. If a non-GET method returns or modifies another user's data, it may indicate IDOR via Method Swap, enabling data theft, unauthorized modification, or account takeover.
