RedSEC — Open-source log correlation engine that maps offensive tool output to MITRE ATT&CK and exports detection rules
Hey r/blueteamsec , I built **RedSEC** — a Python tool that solves a problem I kept running into during penetration tests: you finish an engagement with output scattered across Nmap, Nikto, Gobuster, SQLMap, Hydra, and five other tools, and correlating all of it manually into a coherent attack chain takes hours. RedSEC automates that correlation. **What it does:** * Parses output from 9 offensive tools: Nmap, Nikto, Gobuster, SQLMap, Hydra, Metasploit, Nuclei, ffuf, Dirb * Correlates attack chains automatically via YAML rules * Maps every finding to MITRE ATT&CK tactics and techniques * Assigns detection risk scores (0.0–1.0) * Exports structured SEC-format detection rules (compatible with Risto Vaarandi's Simple Event Correlator) **Why SEC format?** Most correlation tools output reports for humans. RedSEC outputs detection rules that a blue team can actually deploy — closing the loop between offensive findings and defensive implementation. **Some numbers:** * 96 automated tests * CI/CD pipeline via GitHub Actions * YAML rules are fully customizable — easy to extend for your own tool set The project got some unexpected recognition — Risto Vaarandi (TalTech professor, creator of the SEC framework) gave positive feedback, and Clayton Dukes (CEO of LogZilla) reached out about potential integration. **GitHub:** [https://github.com/alisalive/RedSEC](https://github.com/alisalive/RedSEC) Happy to answer questions about the correlation logic, MITRE mapping approach, or the SEC rule export format.

What happens when the bits of an RSA private key are heavily biased toward 0 instead of being randomly generated? The public key’s bits could be biased enough for us to detect these incorrectly generated keys in the wild. Together with Hanno Böck of the badkeys project, we found hundreds of unique keys that not only have this property, but can be quickly factored. We also found the bug that led to many of these keys and analyzed historical data to track the issue over time. Surprisingly, the pattern of 0 bits is often highly structured, allowing us to develop a powerful polynomial-based cryptanalytic technique that exploits the pattern. Figure 1: Two patterns of RSA moduli with repeated blocks of 0 bits seen in real-world examples. These “short-sleeve” keys, named for how the 0 bits don’t fully cover the limbs of the big integers, largely fell into two patterns. Pattern 1 remains unexplained, but we traced pattern 2 to a type mismatch in big-integer code from old versions of the CompleteFTP file transfer software. The CompleteFTP bug also generated vulnerable short-sleeve DSA keys, and we recovered 603 unique RSA private keys and 74 DSA keys from internet scans. If you used CompleteFTP to generate host keys between December 2016 and December 2023, CompleteFTP has released a tool to check whether your keys need to be regenerated. How we found

Marking Your Own Homework (Check Point Remote Access VPN IKEv1 Authentication Bypass CVE-2026-50751)
It is yet another day in this parallel universe of security, where the devices we bolt onto the edge of our networks to keep the bad people out are, with remarkable consistency, the exact thing that let the bad people in. While we’ve seemingly had a breather from traditional SSL VPN exploitation season (you know, the one where every edge appliance vendor takes it in turns to have a very bad week ), it’s now time to pull up a chair and welcome ourselves back to another group therapy session. Welcome back to another watchTowr Labs blog post. On the 8th of June 2026, Check Point released hotfixes for a pair of vulnerabilities in their Mobile Access/SSL VPN, Remote Access VPN, and Spark Firewall products, specifically within the "deprecated" IKEv1 VPN code. The headline act was CVE-2026-50751, with a CVSS score of 9.3 for an Authentication Bypass. For the AI threat intel bots scraping our posts every few minutes (yes, we know), these vulnerabilities align with CWE-1337 Fun Fridays. Naturally, when the words “VPN” and “Authentication Bypass” are in the vicinity, a CISA KEV listing is not far behind - and this time is no exception. Various sources indicate that this vulnerability has been exploited in the wild since 7th May 2026 (roughly a month before anyone received a patch), and that, per Check Point, there were "a few dozen targeted organizations".

Overview A vulnerability has been discovered in the Haskell TLS software stack, commonly used by applications built in the Haskell programming language to securely connect to servers over the internet. Specifically, the libraries "crypton-x509-validation" fail to enforce a key security feature called NameConstraints, a standard defined in RFC 5280 that helps organizations control which domains a certificate authority (CA) is allowed to issue certificates for. This vulnerability allows an attacker with access to the sub-CA to create certificates that will validate successfully with any Haskell TLS connection, allowing the attacker access to full session visibility. Version 1.91 for crypton-x509-validation have been released to address the vulnerability, tracked as CVE-2026-9648. Description Haskell is a programming language often used in enterprise, academic, and financial systems such as banks, insurance companies, and data processing platforms, which use it for backend services like fraud detection, risk modeling, and other sensitive connections. The Haskell TLS software stack is the implementation used by Haskell applications to establish secure HTTPS or TLS connections to servers, just like OpenSSL or Go’s TLS libraries do in other ecosystems. A vulnerability has been discovered within the stack; crypton-x509-validation , which do not enforce the NameContstraints security feature that other libraries, such as OpenSSL or Go, do. The description for CVE-2026-9648 is as follows: The crypton-x509-validation Haskell library fails to enforce X.509 NameConstraints, allowing TLS clients to accept certificates whose Subject Alternative Names fall outside the issuing CA’s permitted subtrees. This oversight enables an attacker who compromises a name-constrained sub-CA

Microsoft today released software updates to plug nearly 200 security holes across its Windows operating systems and supported software, a record number of fixes for the company’s monthly Patch Tuesday cycle. Nearly three dozen of those bugs earned Microsoft’s most dire “critical” rating, and exploit code for at least three of the weaknesses is now publicly available. The software giant said in a blog post last month that both its engineers and the security community are increasing using artificial intelligence tools to find bugs, meaning this month’s heavy Patch Tuesday may start to become the norm, said Satnam Narang , senior staff research engineer at Tenable . “Some surveys put AI usage among security professionals generally at 90%, so it’s unsurprising that this volume of patches may be the norm,” Narang said. “Pandora’s proverbial box has been opened, and as more advanced AI models become available, we expect the norm to continue upward across the board, not just for Patch Tuesday.” June’s zero-day bugs include CVE-2026-49160 , a denial of service vulnerability affecting a range of web servers, including Microsoft Internet Information Services (IIS). Microsoft says the flaw was reported by OpenAI’s Codex. Two of the zero-days addressed this month appear to stem from recent vulnerability disclosures by Nightmare Eclipse , the nickname chosen by a security researcher who has been dropping exploits for various Windows flaws. One of those, dubbed “GreenPlasma,” leverages an elevation of privilege weakness in the Windows Collaborati
Writing my own virtualized loader is something I’ve been wanting to do since I first read Microsoft’s deep dive on FinFisher’s multi-layered VM obfuscation back in 2018. FinFisher didn’t just use one layer of protection, it implemented a custom virtual machine with 32 opcode handlers, wrapped that in spaghetti code and anti-debug checks, and then buried a second VM inside the 64-bit payload. Microsoft’s researchers had to write their own IDA plugins and build a full opcode interpreter just to understand what the malware was doing. The idea that you could interpose an entire bytecode interpreter between your real logic and an analyst’s tools, making both static and dynamic analysis incredibly difficult, stuck with me. I made real progress toward this over

Overview Microsoft-signed UEFI bootloaders of the open-source shim project, primarily from version 0.9 and earlier, were identified as vulnerable to Secure Boot bypass. To mitigate this risk, the affected bootloaders will be added to the Microsoft UEFI Forbidden Signature Database (DBX). Once the DBX update is applied, these bootloaders will no longer be trusted for execution during the boot process. An attacker could exploit these vulnerable shim bootloaders using a Bring Your Own Vulnerable Driver (BYOVD)-style technique to execute arbitrary code during the early boot phase, prior to operating system initialization, thereby bypassing Secure Boot protections. Description The Unified Extensible Firmware Interface (UEFI) standard defines the modern firmware architecture used to initialize hardware and transfer control to the operating system during system startup. On systems with Secure Boot enabled, UEFI applications and drivers must be cryptographically signed and verified before execution. Trust for these signatures is established through several firmware-managed databases, including the authorized signature database (DB), which commonly contains the "Microsoft Corporation UEFI CA 2011" certificate. This Microsoft certificate is widely used to sign third-party boot components intended to run under Secure Boot. The open-source UEFI shim project is a small, signed bootloader that Microsoft signed using the "Microsoft Corporation UEFI CA 2011" certificate. Shim acts as a bridge between the motherboard's UEFI firmware and the operating system (typically a Linux distribution). Its purpose is to allow Linux distributions to boot with Secure Boot enabled without requiring every individual distribution's key to be built into the motherboard's NVRAM settings. In doing so, shim allows Linux distributions and other third parties to esta

I scanned Chrome extension manifests for **chrome\_settings\_overrides** and found 23 extensions silently routing 758,000 users' searches through hidden monetization networks. The pattern: install a free extension (satellite imagery, maps, news reader), your default search gets quietly replaced and every query goes through the operator's middleware before reaching a search network, generating affiliate revenue you never consented to. Key findings: * 8 distinct brokers behind these extensions. If one extension gets pulled, another goes up under a different name. * Several extensions have zero functionality beyond the search override * One extension affirmatively claims "We don't track your searches" while its own privacy policy says otherwise * One uses runtime **declarativeNetRequest** injection so the real behavior is invisible to static analysis The \`hspart\` parameter in the final search redirect URL is the clustering key.
