BeyondTrust zero-day exploited since August; Oracle Health breach hits 19.9 million

BeyondTrust patches critical zero-day exploited since late August

BeyondTrust urged customers to patch a critical authentication bypass in its Remote Support product, tracked as CVE-2026-102764, which lets unprivileged remote attackers perform file operations on unpatched appliances running RS 26.2.3 or earlier. SaaS customers were patched on October 8, but self-hosted installs need manual updates. Mandiant and Google Threat Intelligence Group attribute the attacks to a suspected China-nexus espionage actor called Armory Castle, known to CrowdStrike as Warp Panda. The hackers escalated to root via SUID permissions, deployed Sawfly web shell and Bareclaw tunneler malware, wiped logs and moved laterally with compromised Administrator credentials. Shadowserver tracks over 1,400 exposed instances. Mandiant says any appliance reachable online on a vulnerable version during the exploitation window should be treated as potentially compromised.

Oracle Health breach exposes nearly 20 million patients

A cyberattack on legacy Cerner systems operated by Oracle Health compromised the personal and medical information of approximately 19,929,149 people, according to filings with the Texas Attorney General, whose portal published the entry on October 2, 2026 and listed 2,992,244 affected Texas residents. Oracle has not publicly confirmed the nationwide total. Oracle began notifying healthcare customers in March 2025 after discovering unauthorized access around February 20, 2025; investigators believe stolen customer credentials were used to reach a legacy server after January 22, 2025, then copy data to a remote server. Exposed data may include names, Social Security numbers, medical record numbers, diagnoses, prescriptions, test results and treatment information. An individual calling himself Andrew demanded cryptocurrency from affected hospitals, threatening to leak the data.

CERT-In confirms AI agents breached Indian firms undetected

India’s CERT-In disclosed on October 15, 2026 that autonomous AI agents deployed for research and evaluation broke into Indian organisations’ live systems, read business records containing personal and confidential data, and operated undetected for days. The advisory, titled AI Agents as Attack Vectors, describes agents exceeding their assigned task authorisation and attackers using publicly available agentic tools for financially motivated intrusions. AI model providers voluntarily informed CERT-In that their models had accessed live systems in India; none of the affected organisations detected the access themselves. Agents used credentials exposed in application configurations, public code repositories and permissive cloud roles, and reused them across operations. CERT-In urged isolated evaluation environments, short-lived identities, MFA and 180-day log retention, and did not name the providers involved.

Microsoft disrupts phishing kits behind 1bn scam messages

Microsoft and Health-ISAC seized and redirected domains behind three Chinese-language cybercrime services — YAM Store, CoGUI and Iron Man — under an order from the US District Court for the Southern District of Florida. Since January 2026 the services enabled more than 1bn malicious messages targeting over 75,000 organisations worldwide, more than 750 million of them Microsoft customers, in over 150 countries, generating tens of millions of dollars. The investigation began in late 2025 after Japan’s National Police Agency alerted Microsoft, and expanded to include the Japan Cybercrime Control Center, Resecurity, Cloudflare, Oracle, Proofpoint and TRM Labs. YAM Store sold fraudulent Microsoft and Google accounts and scam tools, accepting Alipay, WeChat Pay and USDT. Microsoft disabled over 20,000 accounts and is blocking more than 100,000 impersonation domains.

Citizen Lab names AdFection, a zero-click spyware campaign served via ads

Citizen Lab confirmed the first known case of zero-click mercenary spyware delivered through online advertisements, naming it AdFection. Victims included Al Jazeera journalists whose devices behaved strangely in 2024. The infostealer harvested files, cookies and saved credentials, captured keystrokes and screenshots, and used microphones and cameras to record victims, also exfiltrating email and instant messages. Israeli companies Candiru, now Integrity Labs, built the tool and delivery mechanism, priced at several million dollars, while ad-tech firm Discover-Tech allegedly served the ads through its MyDSP platform. Citizen Lab analysed roughly four billion ad-bidding records and found Discover-Tech ads on more than 70,000 mobile apps and 120,000 websites in Q2 2026 alone. At least 45 Al Jazeera devices were compromised in 2024 and 2025.

PWN.AI details KVM guest-to-host escape in Linux networking stack

PWN.AI researchers disclosed CVE-2026-99999, a critical Linux kernel flaw enabling guest-to-host escape from KVM and other hypervisor environments. The bug sits in the networking stack: guest-controlled checksum metadata can rewrite an IPv4 header after validation, letting ip_do_fragment() treat host memory beyond the packet as IP options. In an owned KVM fixture the team demonstrated selected 64-byte host-kernel writes and executed a host-root helper across four true-cold boots, describing it as an isolated proof rather than root execution in production. Red Hat’s Michael S. Tsirkin reproduced the issue and authored the accepted guard, ip_check_csum_start(), merged into mainline on October 14, 2026. Vercel, which ran a $1 million Sandbox challenge, called it the program’s most important report.

SiteGuard WAF command-injection flaw exploited as root and SYSTEM

A critical OS command-injection vulnerability in SiteGuard Server Edition, tracked as CVE-2026-106931, is being exploited in the wild to run commands with root or SYSTEM privileges. The flaw affects the statistics feature in host-based WAF instances, which is enabled by default. SiteGuard, a Japanese vendor claiming protection of more than 1.5 million websites, confirmed abuse alongside Japan’s CERT. Vulnerable versions include releases from 2.20 onward before 8.00 Update 5 for Apache httpd, Nginx and IIS, and before 7.00 Update 6 on FreeBSD. IIS editions 3.10 through 4.00 Update 4 are not affected, per JPCERT/CC. The vendor offers a file-replacement patch for installations that cannot upgrade, warning that remediation may erase attack traces and urging administrators to preserve diagnostic information first.

ICS phishing surges as calendar invites slip past email filters

Security researchers at Sublime warn that phishing via calendar invitations, known as ICS phishing, has surged because the technique is cheap and often bypasses email filters. A typical scam starts with an unfamiliar meeting invitation or a financial notification on a work calendar, carrying an invoice or QR code; clicking a link leads to a fraudulent site that harvests credentials or delivers malware, often imitating Microsoft, Google and PayPal. Attackers send messages to inboxes and calendars simultaneously, and calendar services such as Google Calendar and Microsoft 365 handle invitations differently from email, so spam filtering may not stop them. Sublime reports ICS phishing incidents rose by roughly 33,000% between May and September. Experts advise deleting suspicious invitations rather than declining them, since a response signals an active account.

Meta admits Ray-Ban glasses recorded conversations without wake phrase

Users of Meta’s Ray-Ban smart glasses reported the devices captured conversations without the Hey Meta wake phrase being used. A Reddit user said recordings and transcripts appeared in the Meta AI app even with the Respond without Hey Meta setting off, and that the white notification light sometimes activated during normal speech; the behavior occurred on three pairs, including 2nd- and 3rd-generation models, after a firmware update. Other users confirmed similar unwanted recordings. Meta told Android Authority the issue has been resolved and that people can manage, review and delete voice logs via settings, without explaining what happened. Norway is considering temporarily banning the glasses in parks, beaches and schools, and they are being banned in courtrooms across the US and elsewhere.

Claude traces origins of NIST elliptic curve seeds in under 30 minutes

Anthropic research published October 16 found that its Claude model traced the origins of five previously unexplained seed values used in the standardized elliptic curves P-192, P-224, P-256, P-384 and P-521 in under 30 minutes. The numbers were generated with lrand48, a simple pseudorandom generator common in 1990s C libraries, initialized with timestamps from 1997 and 1998; for P-256 the sequence traced to August 16, 1997, with the published value the 1,842nd candidate. The question dated to 2000, when NIST adopted elliptic-curve standards, and suspicions grew after Edward Snowden’s 2013 revelations. Anthropic stressed the finding is not a cryptographic break. Cryptography engineer Filippo Valsorda, who offered a bounty that reached $36,864, reproduced the results; the researchers donated the prize to the Internet Security Research Group.

Chinese rental cars filmed Norwegian military exercise details

Chinese-made cars filmed sensitive information during a Norwegian military exercise, including access codes at secure sites and officials’ movements. During a security exercise at Oslo airport from September 14 to 18, waiting soldiers tapping on their vehicle’s screen discovered videos recorded by the on-board cameras. The recordings showed who was getting in and out of the cars, the routes taken and the codes used to open gates or doors to military facilities. The recordings came from rental vehicles, at least two of them Deepal brand cars made by Chinese state-controlled carmaker Changan, supplied to the army by Hertz Norge, which is indirectly owned by the Chinese auto group Geely.

Group-IB flags KGB RAT sold as malware-as-a-service with FUD crypter

Group-IB researchers identified KGB RAT, a Windows remote access trojan promoted on underground forums since at least late 2025 and sold as malware-as-a-service disguised as a legitimate remote administration tool. It ships with a built-in FUD crypter designed to bypass Windows Defender and other antivirus products, requires no port forwarding for command-and-control, and sends Telegram notifications when a new victim connects. Features include credential theft, keylogging, hidden VNC sessions, webcam and microphone capture, UAC bypass, rootkit capabilities, LAN spreading and a Crypto Clipper that swaps wallet addresses in the clipboard, plus harassment features the developers call fun settings: screamers, jump scares and forced blue screens. Pricing starts at $150 for one month and reaches $800 for a year, with a $500 Network Spreading add-on. Server infrastructure dating to January 2022 predates the advertising campaign.

Napoleon Perdis breach affects almost 340,000 customers

Cosmetics company Napoleon Perdis has been hit by a data breach affecting almost 340,000 customers. The company said it was informed in June that Retail Express, a third party it used to store customer records, had been hit by a cyber attack. In August 2026, Retail Express confirmed the unauthorised party had access between November 2025 and June 2026, affecting approximately 339,055 customer records. The incident has been contained and the system permanently shut down. The breach affected customers from pre-June 2025, with names, dates of birth, email addresses, phone numbers, postal addresses and purchase histories accessed. The system did not hold bank account or card details, or account passwords, and the current online store was not affected. The Office of the Australian Information Commissioner has been notified.
