New Tooling

• Introducing EvidenceForge: Synthetic Security Logs That Don’t Look (as) Fake
  "A lot of important work in security depends on having realistic log data to work with, and a lot of that work gets blocked, watered down, or quietly skipped because the data just isn’t available. The use cases come up constantly: teaching threat hunters, incident responders, and detection engineers with datasets that have known ground truth; validating that a detection fires on the right activity without drowning in false positives; and training ML models that need labeled, balanced, multi-source telemetry at scale. These are different problems with the same root cause. You need realistic, labeled security logs and you can’t get them easily."

• Vigolium: Open-Source Vulnerability Scanner
  "Vigolium, an open-source vulnerability scanner that combines deterministic scanning with AI-driven auditing, launched its initial open-source release this month. The project ships 235+ scanner modules and an in-process agent runtime called olium that handles autonomous endpoint discovery, attack planning, and finding triage. The tool exposes two scanning paths. vigolium scan runs a multi-phase deterministic pipeline covering content discovery, browser-based spidering, and active and passive auditing. vigolium agent hands control to an LLM-driven harness that selects modules, generates custom JavaScript extensions, and runs source-code audits alongside dynamic scans."

• Ebpf101
  "Liz Rice's Learning eBPF — via the Isovalent tutorial — was our starting point, one chapter per directory. The repo has since gone well beyond it. The opening chapters retrace the tutorial's arc (BCC → libbpf/CO-RE → kprobes/uprobes); from there it keeps going — the verifier as a gate, the bpftool workflow, the XDP and tc datapath, tail calls, LSM BPF (policy enforcement), BPF iterators, and two applied capstones the tutorial never reaches: an XDP firewall and a rule-based intrusion-detection system, drawn respectively from a Columbia EECS6891 lecture (Yannis Zarkadas, Spring 2024) and a research paper (arXiv:2102.09980). All 23 chapters are built and run live on this machine; every program is written to be read."

• All Major LLMs Exposed To Multi-Turn Manipulation, Warn Researchers
  "The safety guardrails of several prominent large language models (LLM) can be bypassed if a user tricks the LLM into having a multi-pronged, ongoing conversation, researchers at Cisco have warned. The researchers examined commonly used LLMs and frontier AI models including OpenAI’s ChatGPT, Anthropic’s Claude, Google Gemini, Amazon Nova, xAI’s Grok and others to test how their built-in safety guardrails held up against potential threats from real-world attackers. They found that many of the models could be tricked into performing actions they should not be able to."

• How To Get a 100% Conference Acceptance Rate, The Novee Way: A High-Severity CVE In Leading Call-For-Papers Software
  "As a founding engineer and security researcher at Novee, my job is to think like an attacker – and to train Novee’s AI agents to do the same. When I discovered this particular exploit, however, I was doing something ordinary: preparing conference submissions. Different events, different review committees, different deadlines, but I noticed the same submission form kept appearing under different logos. Much of the technical conference world runs its CFPs on pretalx, an open-source platform behind everything from hacker camps to academic symposiums. From the outside, each event looks independent. Underneath, it is one codebase serving them all."

• Don’t Trust ‘secure Mail’! Malicious Files Impersonating Credit Card Companies Are Being Distributed
  "ahnLab recently confirmed the distribution of malicious files disguised as security emails from a major credit card company in Korea. this attack has a similar flow to the Kimsuky group’s past malicious LNK distribution case of disguising password files, but it is characterized by a change in the command execution of the initial LNK file. in particular, the execution of additional files and malicious files and the behavior of the malicious files changed depending on whether the security service of the infected environment was enabled or disabled. let’s take a look at the main behavior of this case and user precautions."

• From Poisoned Search Results To GPU Mining: A Cryptojacking Campaign Abusing ScreenConnect And Microsoft .NET Utilities
  "Microsoft Defender Experts identified an active cryptojacking campaign in which malicious download sites are surfaced not only through traditional search engine poisoning, but also through AI chatbot interactions. This emerging delivery technique extends social engineering beyond conventional search results and increases the visibility of malicious software recommendations. The campaign impersonates trusted system utilities including CrystalDiskInfo, HWMonitor, Display Driver Uninstaller, FurMark, K-Lite Codec Pack, and PDFgear to target users likely to own high-performance GPUs. Rather than maximizing infection volume, the threat actor appears focused on compromising systems with higher mining value."

• Disrupting Glassworm: Inside CrowdStrike’s Takedown Of a Developer-Targeting Botnet
  "On May 26, 2026, at 14:00 UTC, the CrowdStrike Counter Adversary Operations team executed a coordinated takedown of the Glassworm botnet, a global threat targeting software developers through the open-source supply chain. In collaboration with Google and the Shadowserver Foundation, we struck all four of Glassworm's command-and-control (C2) channels simultaneously, severing the operators from their infected machines and their ability to deliver new malicious payloads. This takedown matters beyond the botnet. Glassworm marked a significant shift in the threat landscape that should serve as a wake-up call for every organization that ships or consumes software. Adversaries are no longer just targeting products, they're targeting the developers who build them."

• FBI Warns Of In-Person Data Theft Attacks From Extortion Gang
  "The FBI warned on Tuesday that the Silent Ransom Group (SRG) extortion gang is now targeting U.S.-based law firms in in-person data theft attacks. "As of Spring 2026, SRG actors use a social engineering scheme to pose as an employee from the victim's IT department. SRG actors either directly call or send phishing emails to urge employees to call the SRG actor posing as IT support," the FBI warned in a Tuesday flash alert. "While on the phone, the SRG actor directs the employee to grant access to a remote desktop session. If that attempt fails, SRG sends a threat actor to the victim's location to gain access to insert a storage device into the victim's computer.""

• OverlayPhantom: The Android Banking Trojan Hiding In Plain Sight
  "Cyble Research and Intelligence Labs (CRIL) has identified a novel Android banking trojan, dubbed OverlayPhantom, actively distributed in the wild via malicious URLs. The malware employs a two-stage infection chain, using a dropper application that impersonates trusted platforms, including the official Austrian government identity application, ID Austria, and the widely used consumer platform TikTok, to deceive victims into installing it. Once deployed, OverlayPhantom masquerades as “Google Play Services” and abuses Android’s Accessibility Service to gain persistent, elevated control of the infected device."

• The GHOST STADIUM Score: Billions At Stake At The World’s Largest Football Tournament
  "The 2026 FIFA World Cup is set to be the largest sporting event in history. Hosted across three nations — the United States, Canada, and Mexico — the tournament will take place from June 11 to July 19, 2026, featuring 104 matches played in 16 cities. The scale is unprecedented: FIFA estimates that more than six million fans will fill stadiums, with an average of 450,000 visitors per city. More than 150 million tickets were requested within the first 15 days of the sales window alone, making this edition approximately 30 times oversubscribed compared to previous tournaments. For context, the 2022 Qatar World Cup drew over 3.4 million in-stadium fans with an average attendance capacity of 96.3 per cent. The 2026 edition is expected to nearly double that figure."

• ‘SymJack’ Attack Turns AI Coding Agents Into Supply Chain Attack Delivery Systems
  "Trust and automation are key to many attacks; and trust with automation is inherent in the use of AI coding agents. Malicious repositories are a frequent factor in many supply chain attacks, estimated at between 20% and 40%. Such repositories can be used to fool a developer using an AI coding agent into generating bad code that can silently slip into the CI pipeline. That is just one possibility of the SymJack attack described by Adversa AI. The attack requires three elements: attacker control of the coding agent repo, a ready-made malicious MCP server, and a developer’s use of an AI coding tool."

  "WatchGuard telemetry identified a campaign associated to Grandoreiro that uses the DLL Side-Loading technique abusing four different softwares, targeting banks in Portugal. Also, it was identified cases of a known campaign that uses a malicious VBS to deliver the malware, targeting companies in Spain, Portugal, Mexico and Latin America. Grandoreiro has been active since at least 2016 and is now one of the most widespread banking trojans globally. Despite the disruption of some operators and the joint operations with INTERPOL and local law enforcement resulting in the arrest of gang members in Spain, Brazil, and Argentina, that occurred in 2021 and 2024, they’re still active due to only part of the gang was arrested and the ones that was not arrested are continuing the operations."

  "Gambit Security Threat Intelligence team investigated an intrusion campaign targeting organizations in the United States, Israel, Saudi Arabia, and Turkey: exfiltration across all of them, with destructive operations at a subset. The activity surfaced publicly in late March and early April 2026, after a pro-Iranian persona calling itself Ababil of Minab claimed to have compromised the Los Angeles County Metropolitan Transportation Authority (LACMTA / LA Metro), destroyed systems, and exfiltrated data. Our investigation found that Ababil of Minab is unlikely to be a new, standalone hacktivist crew as they claim."

• Attackers Disguising Phishing As Google AppSheet Notifications
  "Phishing campaigns have become significantly more sophisticated and convincing in recent years. Sender addresses are now nearly identical to the real deal, emails are flawlessly written, and users are called by their names. But what do you do when a suspicious email comes from a clearly legitimate email address? Lately, phishers have been exploiting the Google AppSheet platform to set up email blasts that originate from an official Google-linked address. Following a successful attack, they walk away with their victims’ accounts and sensitive data."

• 62% Of Critical Vulnerabilities Have Exploits Circulating Before Scanners Can Detect Them
  "Eighteen months ago, security teams had roughly four months between a new CVE and a working exploit. As of April 2026, that window is ten hours. We wanted to understand what that compression means for the detection tools most organizations depend on: vulnerability scanners. So the Cogent Research team analyzed 69,159 CVEs published between January 2025 and April 2026, tracking three timestamps for each one: when the CVE was published, when a working exploit became available, and when the major scanner vendors (Tenable, Qualys, and Rapid7) shipped detection signatures. The findings are not encouraging for teams that rely on scanner output as their primary visibility into new threats."

Malcolm Portelli, CISO at Coinflow, runs the company’s security program from Malta. Coinflow is headquartered in the United States and operates across multiple jurisdictions. Portelli sat down for this interview at the Span Cyber Security Arena conference. Portelli says the sector drives his threat model more than the location. “It’s more the industry which we operate in. So, financial services, Web3, and crypto and all that comes with that. Crypto is a big target, especially for the big APTs. They’re always looking at how they can get into crypto firms because that’s their chosen money.”"

• More CVEs, Same Playbook: 2026 Vulnerability Exploitation In The Wild
  "Proofpoint's dual telemetry streams — targeted attack visibility covering hundreds of millions of messages daily, and a global network sensor array that generated over 3 million alerts and identified four undisclosed CVEs in 2026 to date — present a consistent picture: attackers are opportunistic. They grab newly published CVEs when public proof-of-concept code appears, chain them with established techniques, and move on. What has changed is the volume of vulnerabilities feeding that pipeline. NIST reported that CVE submissions in Q1 2026 were nearly one-third higher than the same quarter last year, and that the National Vulnerability Database still cannot keep pace with enrichment. The widely-cited driver is AI-assisted vulnerability discovery: frontier models are enabling both defenders and researchers — and, increasingly, anyone with access to an open-weights model — to surface bugs at machine speed. The exploit window is narrowing, but the exploitation pattern remains recognizable."

• The Credential Crisis: How Stolen Credentials Defeat Modern Security
  "The modern cyber use of the word ‘credentials’ stems from the Latin ‘creder’: to believe. As society evolved into the Middle Ages, the early notion of ‘Believe me. I am Socrates’ became, ‘Believe this physical letter that proves I am Socrates.’ Those physical letters became known as ‘credentialis’, or a paper that authenticated the bearer. In today’s cyber world, we call that paper ‘credentials. It is no longer physical, but virtual, and the meaning has expanded to ‘you can trust in the belief that I am who I say I am and you can treat me as such: I am Socrates.’ Socrates is the identity, and the credentials prove it."

INTRUSION ANALYSIS: China-Nexus Adversary Targeting Southeast Asian Edge Network Infrastructure
"A China-nexus intrusion set has been identified conducting a large-scale campaign targeting edge network devices across Southeast Asia. The adversary deploys a custom Linux ELF implant (router.elf) directly onto compromised border routers, establishing persistent command-and-control (C2) via DNS over HTTPS (DoH) while simultaneously weaponizing the router's iptables subsystem to hijack downstream DNS traffic at scale. Correlated Windows-side tradecraft leverages a cracked Cobalt Strike 4.4 Beacon delivered via DLL sideloading (version.dll), sharing identical C2 infrastructure and malleable C2 profiles with the router implant — confirming unified operational control."

• 2 PhaaS 2 Furious: The Evolution Of Chinese-Language Phishing Services
  "While Russian-speaking threat actors have historically dominated the phishing-as-a-service (PhaaS) landscape, a rival ecosystem is rapidly growing within the Chinese-language underground. Google Threat Intelligence Group (GTIG) analyzed a dozen current PhaaS offerings in the Chinese underground, all of them mature services and many likely tied intricately to the broader criminal ecosystem in that region. These services not only lower the barrier to entry for Chinese cyber criminals, but reveal broader patterns on the evolution of social engineering and credential theft. Late last year, Google took legal action against one PhaaS provider and has worked since then to endorse legislation and enact technical safeguards against these types of scams."

• Fast And Furious – Nimbus Manticore Operations During The Iranian Conflict
  "During the recent geopolitical tensions in the Middle East, we reported on multiple Iran-nexus threat actors advancing Iran’s strategic objectives through cyber operations. These activities included targeting internet-connected cameras, conducting destructive attacks against US and Israeli entities, and exfiltrating data from cloud environments to support broader kinetic and intelligence-gathering efforts. Nimbus Manticore (also tracked as UNC1549) is an IRGC-affiliated threat actor who primarily targets the defense, aviation and telecommunication sectors through career-themed phishing campaigns. Nimbus Manticore stands out compared to other Iranian-linked groups due to its complex malware toolset. In 2025, we documented the MiniJunk malware framework used by Nimbus Manticore to target high-profile organizations across Western Europe and the Middle East."

• Smart Contracts For C&C: How ClearFake Hid In Plain Sight On BSC Testnet
  "TrendAI Research analyzed in May 2026 an intrusion where threat actors used a technique known as EtherHiding to store payload routing instructions inside BNB Smart Chain (formerly Binance Smart Chain or BSC) smart contracts. Unlike traditional command-and-control (C&C) infrastructure, this routing layer cannot be altered, suspended, or seized by security vendors, registrars, or law enforcement due to the immutable nature of the blockchain. TrendAI found that the injected JavaScript on compromised websites queried these contracts to retrieve and route victims to the next stage of the attack chain."

• Dark Web Profile: CoinbaseCartel
  "CoinbaseCartel is a financially motivated threat actor that emerged on the Dark Web in September 2025. Unlike traditional ransomware groups, the group does not encrypt victim systems. Instead, it relies exclusively on data theft, threatening to publish exfiltrated data on its dark web leak site unless victims pay a ransom. This approach is commonly described as a single-extortion model. The group’s name carries no connection to the legitimate cryptocurrency exchange Coinbase. On its leak site, CoinbaseCartel describes itself as “redefining data extortion” and explicitly states that its operations have no political, personal, or activist agenda."

• 2026 Cloud Security Report: Why Traditional Network, Cloud, And Security Architecture Are Lagging Behind The AI Transformation
  "As AI rapidly reshapes industries, the role of the cloud has become even more critical. From automated customer experiences to intelligent cyber security and predictive analytics, AI transformations are increasingly being built on a cloud-first foundation. Over the past two years, AI has swiftly moved from an experimental state to an operational reality, with every leading organization embedding AI into the core of how they build, operate, and compete. However, security architectures have not kept pace with the AI transformation. Closing that gap requires more than incremental fixes. It demands a rethinking of how security is designed, deployed, and enforced across hybrid environments."

• Why Network Segmentation Projects Fail: Four Patterns
  "In previous blogs, I’ve discussed why segmentation matters, the challenges of getting it right, and the benefits that organizations see when they fully commit to both macro- and micro-segmentation. Today, I want to flip the question around. Instead of asking what happens when segmentation succeeds, let’s ask: why do so many segmentation projects fail. That question is the focus of the newly released Cisco 2026 Segmentation Report, which draws on a survey of 400 failed segmentation projects at U.S.-based organizations with 500 or more employees. The findings are illuminating—and occasionally surprising."

• The Hackers Behind Shai-Hulud: Lucky Or Skilled?
  "TeamPCP has made a name for itself as a scourge of the open source community following its particular waves of the Shai-Hulud attacks, but the group's attack history is less "sophisticated threat actor" and more "right place, right time" luck. A financially motivated threat actor, TeamPCP formally emerged in late 2025, making a name exploiting the React2Shell vulnerability as well as targeting misconfigured Docker APIs and Next.js. As researchers from Flare recently noted, the group would historically use opportunistic compromises to conduct ransomware, steal data to turn around and sell, and mine cryptocurrency."

• 62% Of Database Ransom Wallets Were Never Paid
  "We built a five-year census of 65,907 exposed databases on the public internet. 30,515 of them (46.3%) carry a ransom or wipe marker. We then validated every bitcoin address inside those notes, ending with 514 distinct attacker wallets. When we priced the 512 we could resolve on-chain, 318 had received zero bitcoin. The 9.78 BTC (around $753,000) that did move concentrated into a handful of operators. Mass database extortion is industrial, automated, mostly unpaid, and still doing enormous damage."
