r/cybersecurity Just now

Verizon's 2026 Data Breach Investigations Report dropped and a few numbers stand out: \- Vulnerability exploitation now 31% of initial access, surpassing stolen credentials for the first time in 19 years of the report \- Human element still present in 62% of breaches (up from 60%) \- Mobile-centric social engineering up 40% year over year \- Shadow AI use by employees tripled to 45% \- Third-party / supply chain involvement jumped 60%, now in 48% of breaches The mobile social engineering jump is the one I find most interesting. As people get better at spotting traditional email phishing, attackers are pivoting to SMS, voice, and messaging apps, and that's where most awareness programs still have the biggest gap. Where do you think the next investment should go: patching cadence, layered controls on mobile, expanding awareness beyond email, or something else?

Came across this paper and thought it was worth sharing here since it addresses something that comes up a lot in ML-based detection discussions. The core problem it tackles: you cannot train a good detector for malware families you have not seen yet. By the time enough real samples of a novel strain exist to retrain your models, it has already done damage. This is one of the reasons signature-based and even ML-based detectors consistently struggle with zero-day malware. The practical value here is the counter-approach. Train a generative model on known malware behavior, let it learn the underlying statistical patterns, then use it to synthesize plausible variants that do not exist yet in the wild. Add those to your training data before you train your classifier. Your detector now has exposure to malware shapes it has never actually seen in the real world. They tested this on the CICMalDroid 2020 Android malware dataset using random forest, XGBoost, and a sequential neural network. Detection accuracy improved across all three, with the biggest gain on the sequential model at around 3.5%. Smaller but consistent improvements for adware and banking malware categories, which are exactly the categories where real-world sample volume tends to be thinner. What I found most relevant for defenders is the threat model it responds to. Attackers are already using AI to mutate and obfuscate malware faster than security teams can collect and label samples. This gives the defensive side a way to use the same generative technique to get ahead of variants rather than always chasing them. One honest caveat from the paper worth knowing: generative models can degrade over time if they are not fed new real samples. This works as a supplement to real data collection, not a replacement for it. Paper by Mohammad Alharbi from North Dakota State University and Jeremy Straub from the Center for Cybersecurity and AI at the University of West Florida.

Cloudflare’s Threat Events provides security analysts with a window into the global threat landscape. The platform offers a peek into the immense traffic that Cloudflare processes every day, so you can see in real time which IPs are attacking specific industries or which threat actors are trending globally. However, translating that visibility into active mitigation has often been a manual, reactive process. Security teams have faced a recurring frustration: knowing that certain IP addresses were associated with specific threat actors (like Tycoon 2FA or RaccoonO365 ) or had been seen targeting their specific industry in other regions, but they couldn't easily automate the blocking of these high-risk IPs within their own WAF unless they manually configured the rules. We are excited to announce a new integration that brings Cloudflare’s vast threat intelligence directly into your WAF engine: you can now write proactive rules using live intelligence data . This means you can add more intelligence context to protect your application against known bad actors — before they even attempt to touch your infrastructure. By populating specialized fields during the early stages of a request, the WAF can now screen traffic based on: Who is attacking by matching specific threat actor names Who they are targeting via the industry or country filters to see who the IP has targeted in the past What type of attack using enriched

r/computerforensics Jun 7

Slapping an LLM onto a security tool without guardrails is a massive liability. In digital forensics and incident response (DFIR), an AI hallucination can ruin an entire chain of custody. An answer without mathematical, binary proof is completely worthless. If an AI agent cannot anchor its reasoning to exact offsets, hashes, and unmanipulated timestamps, it has no business touching forensic data. With **Crow-Eye v0.11.0**, we are pushing a massive update to our full-spectrum forensic lifecycle platform. This release introduces a hardened AI compliance architecture and completely upgrades the core correlation engines. We are treating the underlying intelligence layer like a highly supervised junior analyst. Everything it sees is hashed, everything it thinks is visible, its memory management is strictly audited, and its ability to alter rules is completely sandboxed. Here is exactly how we are enforcing forensic integrity under the hood in v0.11.0: # 1. AI Compliance & Governance # Evidence Seal & Cryptographic Chain of Custody Every single time the AI interacts with your forensic data, it is cryptographically verified. * **The Process:** Before any payload is passed to the AI model, the `evidence_seal.py` service steps in. * **Hashing & Provenance:** It calculates the SHA-256 hash of the exact bytes being sent and attaches metadata tracking the absolute source (e.g., `database:table:rowid`), token count, and the specific AI model used. * **Hash-Chaining:** This metadata is written to an append-only JSONL ledger. Each new record incorporates the hash of the previous record. If a single byte of historical evidence is tampered with, the entire cryptographic chain breaks instantly. # The TruncationAuditor Service (Context Auditing) AI context windows are a massive compliance bottleneck. Silent truncation—where a tool quietly drops data when limits are exceeded—is unacceptable in an investigation. The `TruncationAuditor` service acts as a strict forensic bookkeeper to log exactly how history is modified during our Self-Healing Context routine. * **The Append-Only Audit Log:** Events are permanently written to `<case>/EYE_Logs/truncation_audit.log`, tracking whether data was compressed (`SUMMARIZED`) or entirely removed (`TRUNCATED`). * **High-Fidelity Tracking:** Every single dropped or compressed message records its unique Message ID, token count, reason (e.g., `budget_exceeded`), extra JSON metadata, and a SHA-256 Content Hash of the exact message text to mathematically prove what was removed. * **Tamper-Evident Hash-Chaining:** Each log entry combines its content with the hash of the previous log line using a `chain=...` signature. If a rogue actor manually deletes a record from the text log to hide missed evidence, the chain breaks instantly, and the `verify_chain()` check fails. * **Protocol Compliance Panel:** The auditor exports this ledger into a structured JSON array (`audit_trail.json`). The React UI reads this to give investigators a clean visual timeline of exactly what was preserved, summarized, or dropped. https://preview.redd.it/7yysi31xgu5h1.png?width=3394&format=png&auto=webp&s=16032abda1bbbccd2986be1479e37a0c45ec5a69 # The ThinkingStep Protocol (Anti-Black-Box Streaming) The AI is hard-coded to "show its work." The `ThinkingStep` protocol bridges the Python backend (`eye_bridge.py` and `query_processor.py`) and the React frontend (`EyeDialogue.tsx`), streaming real-time updates over `QWebChannel` across 4 distinct, auditable phases: * **Phase 1: thinking (Intent Detection):** The backend queries the LLM to determine intent (e.g., separating general questions from direct MFT queries). The UI displays "Analyzing request..." * **Phase 2: rag (Retrieval-Augmented Generation):** The backend searches local forensic rules inside `configs/knowledge_base/` (like pulling up Living off the Land tactics for PowerShell analysis) and shows you exactly what was fetched. * **Phase 3: tool\_call (Execution):** If the AI needs hard data, it sends a structured command to the backend to fire off a tool (e.g., executing a raw SQLite database query). The UI displays a dedicated "Tool Execution" block exposing the exact arguments, execution status, and raw JSON payloads returned. This layer loops sequentially if multiple tools are required. If a tool fails on a bad SQL query, the step turns red, exposes the raw Python exception, and allows the AI to catch the error in its context to heal and try a corrected query. * **Phase 4: synthesis (Final Generation):** The backend bundles the RAG knowledge and tool results securely using the Evidence Seal, routing them to the model to stream out the final human-readable response. * **UI Transparency:** In the frontend, these phases are rendered as interactive, collapsible accordion blocks. You can expand a tool block to verify every database query syntax or piece of documentation the AI used before arriving at its final conclusion. # Governance Enforcement Protocols (GEP Rules 9-11) When the AI acts as an author (like generating correlation rules), it is locked down: * **Reasoning Required (R9):** The AI cannot create or edit any rule without rendering a clear text justification. * **Evidence Linking (R10):** The AI cannot hallucinate a rule. It must bind it back to the exact physical forensic artifact (`related_evidence`) that prompted it. * **Read-Only Built-ins (R11):** The AI is strictly sandboxed from modifying human-authored rules or built-in system defaults. # 2. Core Engine Upgrades With the AI heavily supervised, v0.11.0 also delivers massive architectural upgrades to the data engines feeding the platform. **Advanced Core Correlation Engine Upgrade** An adversary leaves footprints across multiple layers of the system simultaneously. * **Deep Artifact Stitching:** Crow-Eye automatically maps the connective tissue between Master File Table (MFT) records, Registry hives, LNK files, and Jump Lists. * **Instant Timeline Reconstruction:** The engine identifies non-obvious relationships instantly, allowing you to trace an execution lifecycle from initial file access straight to system persistence without manual cross-referencing. **Ironclad Identity Engine Upgrade** Attributing actions to specific security identifiers (SIDs) in modern Windows 11 environments can get incredibly messy during high-stress triage. * The upgraded **Identity Engine** brings precise, deterministic execution-context tracking. It resolves user sessions, elevation states, and mapped SIDs with absolute certainty, eliminating ambiguity during credential abuse investigations. For the next release, I am focusing completely on user bugs and performance edge-cases.

There isn't a CIO on the planet not worried about AI spend right now. CFOs are increasingly nervous, too. For fear of falling behind, many companies have pushed their employees to use AI as aggressively as possible. The edict was clear: "Move fast, we'll figure out the bill later." And for the most part, it worked: AI has been genuinely transformational for the teams that leaned in. But the costs are real: we’ve heard countless horror stories of huge bills and painful overages on token spend. Today, we're announcing spend controls in Cloudflare AI Gateway, and a closed beta for identity-driven budgets and routing using Cloudflare Access and your existing identity provider. As we’ve spoken with hundreds of companies about their AI strategy, we’ve seen a common story: The company gives every engineer access to frontier models through a shared API key. Usage takes off. At the end of the month, finance pulls the invoice and nobody can explain where the money went. Was it the machine learning team training a new pipeline? Was it an intern running Claude Opus on email triage? Was it a runaway continuous integration job that burned through 50 million tokens in a weekend? Nobody knows, because the API key doesn't tell you who used it. Without guidelines, staff will generally reach for the biggest model available. And why wouldn't they? If there's no budget, no visibility, and no routing logic, the rational move is to use the most powerful model for everything. The problem is that most tasks don't need a frontier model. A code review summary doesn't need the same model as a complex architecture refactor. A log parser doesn't need the same model as a customer-facing content generator. It should be easy to select the right tool for the job, rather than defaulting to the most powerful and expensive one. And it should be simple to see where the spend is going. You can't calculate ROI on your AI spend without visibility on wh

VoidZero, the company behind Vite , Vitest , Rolldown , Oxc , and Vite+ , is joining Cloudflare. As part of this change, all team members of VoidZero are joining Cloudflare, too. Before saying anything else, we want to make the most important thing clear: Vite, Vitest, Rolldown, Oxc, and Vite+ will stay open source, vendor-agnostic, and community-driven. Nothing about that changes. Cloudflare's mission is to help build a better Internet. And a better Internet is an open Internet. Developers need choice, frameworks need a neutral foundation, and applications need to be portable. It is not reasonable to expect the entire web ecosystem to build around a single vendor. The most important tools and frameworks are portable by design. Vite is one of the few foundational tools that the whole JavaScript ecosystem agrees on. It earned that position by being fast, excellent, portable, and vendor-neutral. One of the best ways Cloudflare can help build a better Internet is by investing in that foundational open source toolchain.

Some recent route hijacks reported by Spamhaus captured our attention. In many of these hijack attempts, an apparent bad actor took advantage of unused autonomous system numbers , or ASNs. Notably in these hijacks, the actor appears to be creating fake AS_PATHs toward destinations, misdirecting traffic down an unexpected path. By creating forged AS_PATHs, the hijacker is attempting to lead traffic somewhere it isn’t normally meant to go while also trying to conceal their identity. A hijacker could strip enough information away from a network path that they could pretend to be the origin of a Border Gateway Protocol (BGP) prefix themselves. Attackers can use this hijacked route to intercept traffic and for other nefarious purposes. There is a simple solution for these cases: basic verification that a BGP peer autonomous system (AS) always includes their network as the “First AS” in an advertised route. To get a sense of how well these safeguards are implemented, we stress-tested several major networks and researched their BGP implementations. Read on to see what we learned. Examining route hijacks involving forged paths The idea that an actor is creating fake AS_PATHs is supported when we take a closer look at implausible AS relationships in the path. For example, let’s examine one of the hijacks reported by Spamhaus, involving a prefix belonging to Orange S.A., the French telecom company. Using the monocle tool, we can

Public skill marketplaces are being flooded with malicious skills that steal credentials, exfiltrate data, and hijack agents. In response, a segment of the security industry released skill scanners, a new family of tools designed to detect malicious skills before they’re installed. But we tested them, and they don’t work. We recently bypassed ClawHub’s malicious skill detector , Cisco’s agent skill scanner , and all three of the scanners integrated into skills.sh . These were not advanced attacks: it took us less than an hour to conceive and implement three of the four malicious skills in trailofbits/overtly-malicious-skills , using standard tricks and rapid inspection of the scanner source code. The fourth malicious skill took a few hours, but only because the prompt injection required some trial and error. Our findings demonstrate that even when skill scanners have some defenses, their static nature gives an adversary unlimited bites at the apple to tweak an attack until it finds a way through. Why skill security matters Software supply chains have long been the soft underbelly of computer security. As fragile infrastructure susceptible to both insider threats and external attackers, these supply chains were vulnerable enough when malicious code was the sole vector of compromise. But the rise in agentic systems has spawned a new style of dependency—the skill—and with it a whole new ecosystem of marketplaces and distribution channels that now run alongside traditional package managers.

CVE

Overview VoLTE deployments on Verizon’s IMS network have operated without negotiated SIP integrity protection. In observed test conditions, SIP signaling—including registration, call setup, and messaging—traveled without IPsec ESP encapsulation and without SIP Security Agreement headers, exposing it to interception and modification by on-path attackers. Recent carrier configuration updates, including Apple’s iOS 26.5 carrier bundle released on May 11, 2026, include IMS IPsec–related settings. However, such configuration entries do not confirm active deployment, successful negotiation, or functional protection in production. Description CVE-2026-10629 Verizon IMS deployments were observed transmitting SIP signaling without integrity protection. REGISTER exchanges lacked Security-Client, Security-Server, and Security-Verify headers, and no ESP-encapsulated SIP traffic was detected during subsequent signaling such as INVITE, MESSAGE, BYE, and UPDATE. This pattern persisted across devices, operating systems, and network conditions, indicating a deliberate network configuration rather than a transient issue. Per 3GPP TS 33.203 and GSMA IR.92, SIP signaling between the UE and P-CSCF must be protected using IPsec ESP following IMS AKA authentication, with negotiation occurring during registration. The absence of this protection allows attackers to manipulate SIP signaling undetected, enabling call hijacking, spoofing, denial-of-service, and misrouting of emergency calls. Verizon initially acknowledged the issue and stated that integrity support would be available upon request and extended broadly later in the year. However, the company has since ceased participation in coordination, including follow-up discussions and draft review, and has not provided verifiable evidence of mi

Overview A stored cross-site scripting (XSS) vulnerability has been discovered in Appsmith, specifically in the CodeMirror based SQL query editor’s autocomplete renderer. CVE-2026-7299 has been assigned to track the vulnerability. An attacker with developer level access to a shared PostgreSQL datasource can inject arbitrary JavaScript by creating malicious database objects whose names contain XSS payloads. Successful exploitation leads to arbitrary JavaScript execution in the browser of any workspace member who triggers SQL autocomplete, enabling session hijacking, privilege escalation, or credential theft. Version 2.1 of Appsmith fixes CVE-2026-7299. Description Appsmith is an open source, low code platform intended to allow developers to build internal tools, dashboards, and applications using a UI builder, database and API integrations, and JavaScript customization. Appsmith can also be deployable either self-hosted or via the cloud. A vulnerability, tracked as CVE-2026-7299, has been discovered, allowing for XSS within the SQL query editors autocomplete function. The vulnerability description is below. CVE-2026-7299 Appsmith’s SQL query editor’s autocomplete functionality fails to sanitize database object names before rendering them in innerHTML, allowing an authenticated Developer to inject persistent XSS by a malicious table or column names triggering arbitrary code execution in the sessions of other workspace members when they interact with the same datasource. This vulnerability requires an account with developer access. A developer Appsmith account is an account designed to create, edit, and delete apps within a workspace they are assigned to. When an administrator opens the SQL editor and triggers autocomplete (e.g., by typing SELECT * FROM), the malicious ta

Overview The Collibra Platform Agent contains vulnerabilities that can be chained by a remote, unauthenticated attacker to achieve remote code execution. An attacker can exploit these issues by uploading a crafted ZIP archive that writes attacker-controlled files to arbitrary locations on the server once extracted, resulting in code execution. Description Collibra Platform (CP) and Collibra Platform Self-Hosted (CPSH), an enterprise grade, cloud-based platform designed to help organizations locate, understand, trust, and manage their data assets. The Collibra Agent of CP and CPSH that is installed on the host system is an independent service that listens on different port than the web interface and have the following vulnerabilities. CVE-2026-10622 Privileged REST endpoints exposed under /rest/* do not properly enforce authentication or authorization. This allows a remote, unauthenticated attacker to interact with sensitive application functionality and gather information useful for further exploitation, including identifying suitable filesystem locations or application paths. Additionally, the web services hosting the vulnerable REST endpoint was observed to bind to all available network interfaces regardless of the setting passed to the installer script. This behavior may increase exposure in deployments where administrators believe access is restricted to specific interfaces or trusted networks. CVE-2026-10621 A Zip Slip vulnerability during extraction is exposed through POST /rest/restore and enables path traversal. When a ZIP archive is processed, file paths contained within the archive are not properly validated or canonicalized before extraction.
