US officials believe Iranian-affiliated actors broke into internet-exposed automatic tank gauge (ATG) systems at gas stations across multiple states, then changed the displayed fuel levels without altering the actual amounts. The intrusions caused no shortages, but falsified ATG readings could theoretically hide a real fuel leak. ATGs have been a known soft target for over a decade. The activity tracks with a broader Iranian push during the war that began in late February: disruptions at US oil, gas, and water sites, shipping delays at Stryker, and the leak of FBI Director Kash Patel's emails. Attribution is preliminary because intruders left almost no forensic evidence.
Researchers at Cyera have disclosed a chain of four vulnerabilities in OpenClaw, an open-source autonomous AI agent platform that Nvidia and Tencent have built enterprise products on top of. The chain - CVE-2026-44112 (CVSS 9.6), CVE-2026-44113, CVE-2026-44115, and CVE-2026-44118 - lets an attacker who can influence the agent's input (through a malicious plugin, prompt injection, or compromised tool output) break out of the OpenShell sandbox, read environment-stored API keys, elevate to owner-level privileges, and write persistent backdoors. Each step looks like normal agent behavior. Shodan and Zoomeye between them counted 65,000 to 180,000 public OpenClaw instances earlier in May. All flaws are fixed in OpenClaw 2026.4.22.
A wave of critical patches landed across enterprise vendors. Fortinet shipped fixes for two unauthenticated code-execution flaws (CVE-2026-44277 in FortiAuthenticator, CVE-2026-26083 in FortiSandbox / FortiSandbox Cloud / FortiSandbox PaaS, both CVSS 9.1). SAP patched a 9.6-rated SQL injection in S/4HANA and a missing-auth check in SAP Commerce that allows unauthenticated code execution. Ivanti Xtraction got a fix for arbitrary file read and write. Broadcom patched a VMware Fusion macOS local-privilege-escalation (CVE-2026-41702). And the n8n automation platform shipped five CVSS 9.4 issues, including XML-driven prototype pollution that authenticated workflow editors could turn into RCE.
An Amazon S3 bucket simply named 'tabiq' was left open to anyone who knew the name, exposing over a million passports, driver's licenses, and identity-verification selfies submitted by hotel guests worldwide. The platform, run by Japanese operator Reqrea, handles digital check-in. Researcher Anurag Sen found the bucket and notified TechCrunch and JPCERT; the bucket has since been locked down. Reqrea says the exposed files date from early 2020 through May 2026 and that it does not yet know how the bucket became public. The company is still reviewing access logs to determine whether anyone else accessed the data.
Have I Been Pwned has added Colombian buy-now-pay-later fintech Addi to its breach corpus with 34,532,941 unique email addresses. Addi acknowledged unauthorized activity on its platform back in March 2026 and warned customers that personal data might have been compromised. ShinyHunters then claimed responsibility and published the dataset, which goes well beyond emails: credit-scoring requests, credit bureau records, customer identity files, email-validation logs, Cedula de Ciudadania national ID numbers, estimated income, socioeconomic level, and purchase history. Addi is a Bogota-based BNPL lender with $1B+ in funding and is one of the larger Latin American fintech breaches publicly documented this year.
A researcher who goes by Chaotic Eclipse has dropped working proof-of-concept code on GitHub for a Windows local privilege escalation that gives SYSTEM access on fully patched Windows 11 Pro and Windows Server 2025. The bug lives in the Cloud Filter driver cldflt.sys and is, the researcher says, the same flaw Google Project Zero reported to Microsoft as CVE-2020-17103 in 2020, which Microsoft said it fixed in December 2020. The original Google PoC works unmodified. May 2026 Patch Tuesday updates do not stop it. The same researcher has dropped several other Windows zero-days in recent weeks, all of which were quickly seen in real attacks.
The 18-year-old heap overflow in NGINX's rewrite module, CVE-2026-42945, disclosed last week as part of the 'Rift' bug cluster, is now seeing real exploitation attempts. AI-native security firm VulnCheck says its honeypot networks have caught attackers probing the flaw, though the goal of the campaigns is not yet clear. The vulnerability lets an unauthenticated attacker crash NGINX worker processes by sending crafted HTTP requests. Turning that crash into remote code execution requires the target host to have Address Space Layout Randomization (ASLR) disabled, which is uncommon by default, but the worker-crash denial-of-service is exploitable on its own and rated urgent.
The Tycoon 2FA phishing-as-a-service kit, which Microsoft, Europol, Cloudflare and others tried to dismantle in March 2026, is back and has switched tactics. Instead of relaying credentials and MFA codes through a fake login page, operators now send victims to Microsoft's legitimate device-login page at microsoft.com/devicelogin and ask them to enter a code from the lure email. That single consent grants the attacker OAuth tokens for the victim's Exchange Online, OneDrive, and SharePoint through Microsoft's own Authentication Broker app, so it looks normal in Entra logs. eSentire spotted the late-April campaign and published IoCs, including AS45102 (Alibaba Cloud) operator infrastructure.
VulnCheck says attackers are chaining three critical bugs (CVE-2026-28515, CVE-2026-28517, CVE-2026-28516) in openDCIM, an open-source data center management web app, to drop PHP web shells on exposed installs. All three rate CVSS 9.3 and cover missing authorization, OS command injection, and SQL injection. They can be combined over five HTTP requests to land a reverse shell. The activity comes from a single Chinese IP using what VulnCheck describes as a customized version of Vulnhuntr, a public AI-driven vulnerability discovery tool. The campaign is one of the first publicly documented cases of an open-source AI vuln scanner being repurposed for real-world exploitation.
Grafana Labs says an attacker stole a token that gave access to its GitHub environment, downloaded the company's private codebase, and then demanded a ransom to keep the code from being published. Grafana refused to pay and cited FBI guidance against rewarding extortion. The company says no customer data was accessed and the compromised credentials have been invalidated. A data-extortion crew called CoinbaseCartel, tied to the same ecosystem as ShinyHunters, Scattered Spider, and LAPSUS$ with around 170 victims since September 2025, claimed credit. Grafana has not disclosed which code was taken or when the intrusion happened.
