The Instagram accounts for the Obama White House and the Chief Master Sergeant of the U.S. Space Force were briefly defaced with pro-Iranian images and messages over the weekend, after instructions began circulating on Telegram showing how to trick Meta’s “AI support assistant” bot into resetting account passwords. A screenshot from a video released on Telegram claiming to show how Meta’s AI customer support bot could be tricked into resetting a target’s password. On May 31, word began to spread on several Telegram instant message channels that Meta’s AI bot would happily add an email address to an existing account as part of the bot’s standard password reset flow. A video released on Telegram by pro-Iran hackers claimed to document a remarkably simple exploit that appears to have involved using a VPN connection with an IP address that is in or near the target’s usual hometown, requesting a password reset for the account, and then choosing to chat with Meta’s AI support assistant. From there, the video shows the attacker told the bot to link the account in question to a new email address, after which the bot dutifully sent that address a one-time code that allowed a password reset. The Telegram account that posted the video also linked to screenshots of pro-Iran images, videos and messages that defaced the hacked Instagram accounts, saying hackers had used the exploit to hijack a number of valuable (read: short) Instagram account names that allegedly have a resale value of more than a half million dollars. Meta has not res
A major npm supply-chain incident reportedly hit the @redhat-cloud-services scope, with malicious versions published through an OIDC trusted publishing gap.

Cloudflare's core is the centralized data centers that run our control plane, billing, and analytics -- distinct from the globally distributed edge that handles user traffic. Core servers are bare metal, and when issues happen during reboot, the consequences can cascade fast. Their boot sequence is orchestrated by UEFI , the modern firmware standard that initializes hardware and hands off control to the operating system. Small quirks in that handoff can have outsized consequences. After a routine firmware update, some of our core servers were taking four hours to come back online, rather than just minutes as they did before. What should have been a one-day fleet-wide rollout was stretching into multi-day slogs. New nodes faced the full timeout gauntlet on their very first boot. Maintenance windows ballooned. Engineering teams had to babysit upgrades that should have run unattended. This issue affected the entire Gen12 fleet -- nearly 2,000 units. Every unexpected failure mid-upgrade meant restarting the entire cycle, and new capacity sat idle waiting for the timeout gauntlet to clear. This is the story of how we tracked the cause to a firmware quirk and an over-eager linear search through every available network boot interface, and how we cut total boot and upgrade time from hours back down to minutes. Along the way, we'll share what we learned about UEFI internals, vendor-specific quirks, and the automation strategies that ultimately solved the problem. The network boot interface A network boot interface allows a server to boot its operating system over the network instead of from local storage. This is critical for centralized, automated, and scalable control over how machines start up, especially a

@redhat-cloud-services npm scope backdoored with valid signed SLSA provenance; recovered the GitHub commit-search dead-drop C2 markers
On 1 Jun 2026, 31 packages across the redhat-cloud-services npm scope were republished with an install-time malware payload, and it kept re-arming: at least 4 bursts in one afternoon as the registry purged each batch, version numbers climbing each time. What makes it notable for defenders: ## Valid, signed provenance Every malicious version carries valid SLSA provenance and passes `npm audit signatures`. npm trusted publishing authorizes on (repository + workflow file path), so the attacker pushed a throwaway branch carrying a workflow named `release.yml` set to run on any push with `id-token: write`. GitHub Actions ran it in the repo's context, npm minted a real publish token AND a real attestation, then the branch was deleted. `main` was never touched. The scope publishes from more than one RedHatInsights repo (clients from javascript-clients, the MCP servers from platform-frontend-ai-toolkit), so more than one CI pipeline was abused. Provenance proves where a build came from, not what it does. ## IOCs (from a sandbox detonation) C2 is a GitHub commit-search dead-drop, no hardcoded host. The implant queries `api.github.com/search/commits` for marker strings to locate its drop point: - `thebeautifulmarchoftime` - `IfYouInvalidateThisTokenItWillNukeTheComputerOfTheOwner` - User-Agent: `python-requests/2.31.0` Searchable in GitHub commit search / audit logs, and the drop-point commits can be purged. (Not in the public writeups yet; contributed to the issue below.) Behavior: - Env-gated: only fires when `CI` / `GITHUB_ACTIONS` are set (dormant in a bare sandbox), which is why a lot of dynamic analysis misses it. - Credential reads within ms of install: `~/.aws/credentials`, `~/.ssh/id_rsa`, `~/.git-credentials`, `~/.docker/config.json`. - All egress DNS-resolved, no hardcoded-IP C2, no cloud metadata probe in our run. ## Detection - Pin to integrity (lockfile) and expect re-arming: `latest` was malicious far more often than not across the afternoon. - A kernel agent that returns `-EPERM` on credential-file reads kills the job before the C2 fires. - Behavioral checks at publish time catch this regardless of how clean the provenance looks. ## Sources - StepSecurity, original report + writeup: https://github.com/RedHatInsights/platform-frontend-ai-toolkit/issues/57 and https://www.stepsecurity.io/blog/multiple-redhat-cloud-services-npm-packages-compromised - SafeDep, the OIDC/SLSA provenance-abuse technique (AntV wave): https://safedep.io/mini-shai-hulud-strikes-again-314-npm-packages-compromised/ - Recovered C2 markers contributed to the RedHatInsights issue: https://github.com/RedHatInsights/platform-frontend-ai-toolkit/issues/57#issuecomment-4594221102 - Full first-hand method (detonation, provenance anatomy, checksums): https://leitwacht.eu/blog/valid-provenance-malicious-package Disclosure: I founded Leitwacht; the agent referenced is our open-source CE binary.

Don’t get pwned; get real-time alerts & prevent breaches #SecureYourSite Today, I loaded the 1,000th data breach into Have I Been Pwned . Reflecting on that milestone number, I pondered how to mark the occasion in writing, and what immediately came to mind was a very simple question: why is it still needed? Especially considering the emergence of privacy regulations such as GDPR and CCPA in the 12 and a half years since I started HIBP, what possible purpose does it still serve? The title kinda gives the answer away, and the big number we hit today coincided with another pattern that makes everything worse: increasingly long lag times for disclosure. This is all going to be anecdotal, and as far as I know, there are no hard numbers for me to cite, but the evidence is everywhere. Here's what I mean: New breach: Cruise operator Carnival was targeted in a ShinyHunters “pay or leak” attack last week. 8.7M records with 7.5M email addresses and loyalty program data were published yesterday. 85% were already in @haveibeenpwned .

Presently sponsored by: Report URI: Guarding you from rogue JavaScript! Don’t get pwned; get real-time alerts & prevent breaches #SecureYourSite I'm finding it quite fascinating to watch the current spate of ShinyHunters breaches and dumps. There's the obvious criminality of it all, but then there's also the response from organisations (or lack thereof, as it relates to disclosure to victims), the appearance and disappearance of victims on their dark web site, the speculation around payments and so on and so forth. And it's seemingly endless - I mentioned DentaQuest during the video, and sure enough, the next day, a 233GB corpus allegedly from them was dropped. By the next update, it might be BCD Travel as well and who knows which other services will appear on the "pay or leak" list. Strange times, I can't remember it ever being this crazy before TBH.

I built an independent benchmark with 20 real CVEs across 15 CWE categories, 5 models (3 OpenAI, 2 Poolside Laguna), three prompt conditions: full advisory, behavioral description only, and location only (file and function, no description of the flaw). I have three findings worth sharing: * **No model reliably fixes real vulnerabilities.** The best solve rate (gpt-5.5) is 50% overall and 60% under the most favorable condition. The failure modes (e.g, wrong-search drift, budget exhaustion mid-implementation, plausible-but-incomplete patches that pass every visible test) are structured and repeatable across models and tasks. * **Token cost varies 4x for equivalent outcomes.** The Laguna models consume 3–4x more tokens than OpenAI models of the same capability tier, with no improvement in solve rate. * **The locate condition is the benchmark's sharpest instrument.** Give a model only a file and function (no description of the flaw). Every model drops. The differences between models are within noise at this scale, but it's the condition that most closely resembles what a security researcher actually does: reading code cold and recognizing independently that something is wrong. Benchmark code and evaluation traces are open sourced.

Discovery During a recent network security assessment, we were working on an environment that was well-hardened – Patching was current, password policies were strong, and network segmentation was in place. So, as part of our enumeration of all network assets, we started looking for default credentials and this led us to multiple Canon enterprise printers configured with default administrator credentials. Enterprise printers are an interesting attack surface because it is common practice to have them configured with domain credentials. So, with administrative access, we tried to execute auth-back attacks by modifying the printer’s configuration to point to our server for credential capture or relay. However, network segmentation controls blocked this attack, as outbound controls prevented traffic from reaching our attacker-controlled subnet. We needed a different approach. We turned our attention to how the printer handled stored credentials. Specifically, we were curious to look at what happened to them during export. While exploring the printer’s administrative interface, we found a configuration export feature that allows administrators to back up device settings. This immediately raised a question: how were stored credentials being protected during export? Canon’s documentation states that exporting sensitive data requires encryption and the web interface presents encryption options (Security Level 1 and 2) that appear mandatory. However, we quickly discovered that these controls are implemented client-side without server-side validation. Vulnerability Canon imageRUNNER ADVANCE DX printers provide a configuration export feature that is accessible through the web management interface. The web UI appears to enforce encryption by requiring a user-supplied pass
In previous blog posts we’ve talked about getting nerd sniped . Today we’re going to talk about a kind of nerd sniping that any offensive security tool creator is familiar with; when your tool gets signatured. This normally kicks off a frustrating spiral of back and forth changes between the tool author and security vendors until the tool author runs out of resources to keep responding to changes. Like many parts of the security space, LLMs have changed how this story might end. The Classic Offensive Security Tooling Lifecycle There’s a lifecycle to most offensive security tooling. First you encounter a problem that’s common or problematic enough that you want to automate it, so you write a tool. Then you use that tool privately until you decide the time has arrived to open source it. This is a cool moment, you get to share your techniques with the community and if you’re really lucky, maybe the fundamental problem your tool exposes is fixed. Much more likely, once it’s open sourced it eventually gets signatured to the point that you

Cloudflare processes more than a billion events every second. Our network spans 330+ cities in 120+ countries. Behind every HTTP request, every Worker invocation, every R2 read operation, there is data, and a lot of it. For years, that data was not very easy to access. It lived in dozens of production databases, ClickHouse clusters, Kafka streams, Google Cloud buckets, BigQuery datasets, and a long tail of pipelines. To answer a simple question like "How many domains that signed up today are in the Top 100 by traffic?", an analyst at Cloudflare had to know which system to ask, what credentials to use, what query language to write, and whether the data they were looking at was sampled, fresh, or seven-days stale. As a result, it was difficult to glean informed insights from the data. To solve this problem, we built two in-house tools: Town Lake, Cloudflare's unified data analytics platform, and Skipper, an AI data agent that runs on top of it. Town Lake is a single SQL interface to everything Cloudflare knows, and Skipper is how anyone at Cloudflare can ask questions in plain English and get correct, auditable answers back in seconds. This is the story of how we built both. The shape of the problem If you have ever worked at a company that went through a hyper-growth period, you know what data sprawl looks like. Ours had a few specific symptoms: Too many disparate systems. A product engineer who wanted to investigate a customer issue might need to query Postgres for account metadata, ClickHouse for analytics events, BigQuery for usage rollups, R2 for raw logs, and Kafka topics for real-time signals. Each system had its own credentials, its own language, and its own retention policy. Sampled data. This is fine for dashboards, but doesn’t work for domains like billing. Our

There’s an increase in Device Code phishing activity, with Kali365 emerging as one of the most active PhaaS. In the last 24 hours alone, ANYRUN recorded 100+ related analysis sessions. The attack abuses legitimate Microsoft device authentication flows. Victims are shown a user code and instructed to enter it into a real Microsoft device auth page, allowing attackers to capture OAuth access tokens instead of passwords. The risk shifts from credential theft to token abuse, while significantly reducing the number of traditional phishing indicators typically used for detection and triage. Deobfuscated Kali365 JavaScript revealed that after a verification gate, the lure deploys a phishing page, launches a legitimate Microsoft device authentication flow, and then polls /api/status/<session\_id> for session states such as captured, expired, and declined. The code also contains lure-template generators for OneDrive, SharePoint, Teams, Outlook, and Voicemail, and a separate Google device-code authentication flow.

On Tuesday, May 26, Iran’s vice president announced that Internet access had started to be restored in the country after being cut off almost three months ago, following the launch of U.S. and Israeli attacks on February 28. Cloudflare Radar data confirms increased activity and indicates a partial restoration of the Internet in Iran. In this blog post, we’ll examine a range of data points that provide a lens into this prolonged shutdown – and the signs that Iran’s citizens are increasingly able to connect once again. As the situation continues to unfold, Radar will have the latest data on Iran’s connectivity . The first shutdown Iranian citizens have experienced two national Internet shutdowns this year. The first began on January 8 around 16:30 UTC (20:00 local time), and we explored the impact seen over the first few days in a blog post . Traffic from Iran remained near zero until January 21, when a small amount of traffic returned, only to disappear a little over 24 hours later. A similar brief restoration also occurred on January 25, before traffic recovered more fully beginning on January 27. The second shutdown In late February, as military strikes on Iran escalated, a second nationwide Internet shutdown began. That sweeping shutdown has persisted for nearly three months. The shutdown began on February 28. On that date, Cloudflare Radar observed a sharp drop in traffic from
A week after Dutch FIOD seized 800+ servers, the hosting network's ASN (AS209847) is still scanning at its normal daily rate
After FIOD seized 800+ servers and arrested two operators on May 18, the ELLIO research team reports that scanning from the network's ASN ranges has continued largely uninterrupted - and that while roughly a third of the recently-active ranges (including the legacy Stark blocks 94.131.105.0/24 and 92.118.232.0/24) have since been withdrawn from global routing, the surviving ranges under AS209847 (WorkTitans / THE.Hosting) are still announced and still scanning, at the network's normal daily rate. The sibling ASNs (AS213999 and the Moscow-based AS33993) remain routed and idle. The recent activity skews toward database and ICS/SCADA discovery = MongoDB, Redis, PostgreSQL, Oracle, LDAP, plus DNP3 and EtherNet/IP - alongside known-exploit probes like CVE-2017-17215 and WinRM.
Threat Intel: Lithuania Investigates B2B Credential Misuse Exposing 600,000 National Registry Records
The Lithuanian Prosecutor General’s Office and the Criminal Police Bureau have initiated a joint investigation into a large-scale data exfiltration incident targeting the **State Enterprise Centre of Registers**. The incident involved the unauthorized copying of over 600,000 records from the country's national Real Estate and Legal Entities Registers. Rather than exploiting an unpatched software vulnerability, the attack mechanics rely on a classic trust-boundary compromise. **The Entry Vector: Cross-Agency Credential Misuse (MITRE T1078)** Forensic tracking indicates that the threat actors executed a series of unauthorized connections originating from foreign infrastructure. The entry vector relied on valid, high-privilege B2B institutional login credentials assigned to external state departments authorized to query the central registry database. Independent statements from legislative and defense officials suggest the specific access pathway was carved out by compromising authenticated accounts belonging to the **Department of Migration under the Ministry of the Interior**. By hijacking these valid inter-agency connection points, the threat actors bypassed perimeter barriers, allowing them to issue massive queries to the backend database without triggering immediate anomaly blocks. **Exfiltration Scope & Impact Profile** The breach was initially identified by internal monitoring in early April 2026, but public disclosure was delayed due to the ongoing criminal inquiry. The exfiltrated data schemas consist of: * Full legal names, dates of birth, and unique national identification numbers. * Registered physical addresses, corporate entity structures, and detailed cadastral/property registry extracts. The Centre of Registers has confirmed that primary consumer-facing vectors - such as telephone contact details, email addresses, bank account numbers, or raw cadastral measurement files - were not part of the exfiltrated datasets. The primary operational risk is tactical intelligence gathering. Security analysts have pointed out that bulk access to unlisted residential addresses linked to legal entities can be leveraged by foreign intelligence services for target profiling, spear-phishing orchestration, or coercion of state personnel, diplomats, and military figures. **Incident Response & Remediation** Following the identification of the unauthorized bulk queries, the Centre of Registers implemented the following controls: 1. Immediate revocation and blocking of all compromised inter-agency institutional accounts. 2. Mandatory credential rotation and strict query-volume throttling across all API and web self-service gateways linked to external state dependencies. 3. The director of the Centre of Registers, Adrijus Jusas, formally stepped down on May 25 following administrative scrutiny regarding legacy IT infrastructure and monitoring gaps. While independent defense officials note the incident matches the operational signatures of state-aligned hybrid surveillance operations, official attribution from the Prosecutor General's Office remains open.
TL;DR: Visit https://sshlabs.compass-security.training to learn more about SSH security. Introduction SSH is a widely used protocol that provides secure access to remote systems. It enables encrypted communication, file transfers, command execution and shell access for system administration. However, when misconfigured, poorly secured or used in an unsafe way, SSH can become an attack vector for attackers. When we perform Linux hardening or infrastructure reviews , we often see that SSH is not used securel

Encrypted DNS in 2026: DoH, DoT, DoQ and DoH3 protocol comparison — including DNS hijacking attack vectors and what each protocol actually prevents
The security angle on encrypted DNS is often oversimplified. DoH prevents ISP-level snooping and basic DNS hijacking, but doesn't protect against a compromised resolver. DoT is easier to detect and block, which has real implications for threat actors trying to exfiltrate via DNS. DoQ is interesting from a security perspective because QUIC's connection ID migration makes traffic correlation harder. Article includes benchmark data and practical server config — but mostly written for the "which threat model does each protocol address" question.

Presently sponsored by: Report URI: Guarding you from rogue JavaScript! Don’t get pwned; get real-time alerts & prevent breaches #SecureYourSite Today, we welcome the 45th government onboarded to Have I Been Pwned’s free gov service: Bhutan. The Bhutan Computer Incident Response Team, BtCIRT, now has access to monitor Bhutanese government domains against the data in HIBP. As Bhutan’s national CIRT, BtCIRT is responsible for consuming threat intelligence and sharing relevant insights with its constituents, helping identify and respond to cyber risks affecting government services and the people who depend on them. This is exactly the sort of organisation the HIBP government service was built to support: national cybersecurity teams using breach data to identify leaked credentials and compromised databases associated with their government domains. BtCIRT now joins the growing list of national CIRTs and government cybersecurity teams using HIBP to better understand their exposure, respond quickly when new breaches appear, and reduce the risk posed by compromised credentials before attackers can take advantage.
