Human Attacker Exploits Marimo RCE, Reaches SSH Bastion in Eight Seconds
Sysdig documents a skilled human attacker exploiting Marimo pre-auth RCE CVE-2026-39987 (CVSS 9.3), reaching an SSH bastion in eight seconds without AI tooling.
Sysdig detailed exploitation of CVE-2026-39987 (CVSS 9.3), a pre-authenticated RCE affecting all Marimo versions that came under active exploitation within hours of disclosure. A human operator used a hand-written Python script to harvest an AWS key from Secrets Manager and SSH into a bastion host in eight seconds, issuing 850+ commands over nine hours. Separately, Hunt.io disclosed an XMRig cryptomining campaign compromising 3,562 Redis servers via SLAVEOF rogue replication and AOF authorized_keys injection. Operation CameraSwarm, linked to a single operator, compromised over 14,000 Dahua IP cameras using CVE-2021-33044 and CVE-2021-33045.
PaperCut Attacker Uses Hundreds of AI Agents to Compromise 440+ Instances
GreyNoise and Blackpoint tracked an AI-assisted actor using OpenAI Codex and DeepSeek agents to exploit PaperCut flaws across 440+ instances in 48 countries.
A suspected Russian-speaking actor exploited the CVE-2026-81578 authentication bypass and CVE-2026-82078 RCE chain in PaperCut NG/MF, compromising at least 440 instances across 395 organizations in 48 countries, heavily targeting education in the US, UK, France, and elsewhere. The actor used hundreds of AI agents powered by OpenAI Codex and DeepSeek plus tools like Mimikatz, SharpHound, Certipy, Rubeus, and Impacket, reaching domain admin at 12 victims and full domain admin at a US high school within seven minutes. Post-exploitation included registry hive collection and Metasploit/Meterpreter payloads, with origin traced to IP 45.142.193.132.
Srsly Risky Biz: America's Drivers Licence Breach is a National Security Disaster
Dark web service Nexus sold 153 million US and Canadian driver's licenses, linked to identity verification firm IDScan under FBI investigation.
Krebs On Security reported that a dark web service called Nexus sold access to 153 million US and Canadian driver's licenses, claiming over a year of continuous exfiltration from a major identity verification company, with roughly 400,000 new licences added in a single day. Krebs verified the data as genuine and linked the incident via circumstantial evidence to identity verification firm IDScan, whose licences of senior US officials including Secretary of War Pete Hegseth appeared in the database; the FBI is investigating and IDScan has confirmed a breach inquiry. The article argues the data has national security implications, citing how Chinese APT espionage (Anthem, Equifax, Marriott, OPM) and Bellingcat investigations exploited leaked databases. Class action suits are being prepared, and the piece calls for stricter oversight of identity verification firms.
Six Chinese AI firms accused of aggressively copying US frontier models
NSA, CISA, and FBI accuse DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun, and Z.AI of industrial-scale distillation of US frontier models via API abuse.
A joint NSA, CISA, and FBI release alleges six Chinese AI firms have extracted capabilities from US frontier models, including Claude, GPT, Gemini, and Grok, since at least late 2024, likely with Chinese government awareness. Tactics include bulk procurement of premium subscriptions with fraudulent accounts, proxy routing to evade geo-restrictions, and prompt injection to force models to reveal hidden chain-of-thought reasoning. Agencies recommend stronger identity verification, monitoring of anomalous usage, and quietly downgrading or adding noise to responses for suspected distillers, while warning these mitigations could frustrate legitimate users.
Manchester Airports Group breached, millions of customers’ data stolen
Manchester Airports Group confirmed attackers stole customer booking and WiFi signup data affecting about 8.7 million customers across three UK airports.
Manchester Airports Group (MAG) confirmed an unauthorized third party obtained customer data tied to car park, lounge and Fast Track bookings and WiFi sign-ups at Manchester, Stansted and East Midlands airports.

Mirage2FA Surge Hits 4,500 US and EU Companies, Abusing Microsoft 365 Login Flows
Mirage2FA phishing-as-a-service campaign hit ~4,500 organizations, mostly US, stealing Microsoft 365 passwords and session cookies to bypass 2FA.
ANY.RUN research links the Mirage2FA phishing-as-a-service toolkit to 4,532 unique organization email domains between 2024 and 2026, with the US accounting for 63.7% of victims. The kit uses adversary-in-the-middle login flows to harvest credentials and session cookies, bypassing MFA on Microsoft 365 accounts. Researchers recorded more than 9,000 potential compromise events and estimated 48% of targeted email addresses were potentially compromised. Hijacked sessions extend to SSO-connected services, enabling impersonation, fraud and further compromise.
China-Linked Jewelbug Uses XG-Web for Government Espionage and Crypto Fraud
China-linked Jewelbug runs government espionage and crypto fraud from a single XG-Web browser-based control framework.
Broadcom's Symantec and Carbon Black detail Jewelbug, a China-based hackers-for-hire group conducting espionage against governments and militaries in the Middle East, Southeast Asia, and South Asia, plus crypto fraud against Chinese-speaking victims. Operations center on XG-Web, a browser-centric remote-access and infostealing framework, with implants spanning browsers, Windows, Linux, and network devices. The group overlaps with CL-STA-0049, Ink Dragon, Earth Alux, and REF7707, and compromised a Middle Eastern government's webmail across 15 tenants.
