🔍 Researchers from the University of Vienna and SBA Research found a flaw in WhatsApp's contact discovery that let them enumerate valid numbers globally, confirming about 3.5 billion registered accounts. By abusing the lookup mechanism they could probe numbers across 245 countries at rates exceeding 100 million checks per hour from a single IP. The technique also exposed public (non-private) keys, timestamps, profile photos and About text, enabling inference of device OS, account age and linked secondary devices, prompting Meta to add rate limits and tighter visibility rules.

🔒 Kunal Mehta, a 45-year-old from Irvine, has pleaded guilty to laundering at least $25 million connected to a wider $230 million cryptocurrency theft. Court documents say Mehta served as a money launderer for a transnational ring that used social engineering between October 2023 and March 2025 to access victims' crypto accounts. Prosecutors allege he created multiple shell companies in 2024, routed wire transfers into bank accounts designed to appear legitimate, and typically charged a 10% fee for converting stolen crypto to cash. Investigators say the group employed mixers, peel chains, pass-through wallets, VPNs, and conversions to Monero, though operational mistakes helped link laundered funds back to the theft.

🔐 Eurofiber Group said its French subsidiary, Eurofiber France, experienced a breach after attackers exploited a software vulnerability to access its ticket management system and exfiltrate data.

Eurofiber says it closed the vulnerability, strengthened controls and engaged cybersecurity experts to support customers.

Instead of paying, it donated the ransom amount to Carnegie Mellon University and the University of Oxford Security Center to support research into cybercrime.

🔒 Security researchers from Socura and Flare found around 460,000 compromised credentials tied to FTSE 100 domains across clear- and dark-web crime communities, including 28,000 entries from infostealer logs. The report notes many companies had thousands of leaks and that password hygiene remains poor, with 59% having at least one user using 'password'. It recommends MFA, passkeys, password managers, conditional access and proactive leak monitoring.

🔒 Eurofiber France disclosed a cybersecurity incident after attackers exploited a vulnerability in its ticket management system and exfiltrated information.

Authorities (CNIL, ANSSI) were notified and an extortion report has been filed while investigations continue.

🔒 Princeton University disclosed a November 10 cyberattack in which threat actors phished an employee and accessed a database used for fundraising and alumni engagement. The attackers exfiltrated biographical information such as names, email addresses, telephone numbers, and home and business addresses for alumni, donors, faculty, staff, and students. University officials say the compromised system did not contain financial data, passwords, or Social Security numbers, and they have blocked the intruders' access while investigating. Affected individuals are urged to verify any communications claiming to be from the university and to avoid sharing sensitive information.

🔒 The Pennsylvania Office of the Attorney General (OAG) confirmed that files containing personal and medical information were accessed during an August 9 ransomware attack and that the office refused to pay the ransom. The incident encrypted systems and disrupted the OAG website, employee email accounts, and landline phones. Researcher Kevin Beaumont identified public-facing Citrix NetScaler appliances vulnerable to CVE-2025-5777 (Citrix Bleed 2) that may have been exploited. The threat actor INC Ransom later claimed responsibility and posted about 5.7TB of alleged stolen data.

🤖 AI companion apps can feel intimate and conversational, but many collect, retain, and sometimes inadvertently expose highly sensitive information. Recent breaches — including a misconfigured Kafka broker that leaked hundreds of thousands of photos and millions of private conversations — underline real dangers. Users should avoid sharing personal, financial or intimate material, enable two-factor authentication, review privacy policies, and opt out of data retention or training when possible. Parents should supervise teen use and insist on robust age verification and moderation.

📰 Jaguar Land Rover reported a cyberattack cost of £196 million ($220 million) for the July–September quarter after the incident forced production shutdowns and staff to be sent home. The breach, announced on 2 September 2025, involved confirmed data theft and was claimed on Telegram by the group Scattered Lapsus$ Hunters. Following a UK government-backed £1.5 billion loan guarantee, JLR says operations, wholesale and supplier financing have been restored and production has resumed under a phased restart.

🚨 Logitech International S.A. confirmed a data breach claimed by the extortion gang Clop and disclosed the incident in a Form 8‑K filing with the U.S. SEC. The company says data was exfiltrated but that the incident has not impacted its products, business operations, or manufacturing, and that highly sensitive fields such as national ID numbers and credit card data were not stored or accessed. Logitech engaged external cybersecurity firms, attributes the intrusion to a third‑party zero‑day that was patched, and Clop has posted nearly 1.8 TB of alleged stolen data.

🔒 Checkout.com confirmed that the criminal group ShinyHunters accessed a legacy third-party cloud file storage system used in 2020 and earlier and is attempting to extort the company. The exposed materials reportedly include merchant onboarding documents and internal operational files, and Checkout estimates the data affects less than 25% of its current merchant base while also touching former customers. Rather than paying, the firm said it will donate the ransom amount to Carnegie Mellon University and the University of Oxford Cyber Security Center and invest in strengthening its security.

🔔 DoorDash disclosed a data breach discovered on October 25, 2025, after an unauthorized third party gained access to certain user contact information when a DoorDash employee fell victim to a social engineering scam. Affected information varied by individual and may have included first and last names, physical addresses, phone numbers, and email addresses. DoorDash says no Social Security Numbers or other highly sensitive data were accessed, and the company engaged a forensic firm, notified law enforcement, and deployed additional security measures.

🔒 The Washington Post says a zero-day in Oracle E-Business Suite was used to access parts of its network, exposing personal and financial records for 9,720 employees and contractors. The intrusion occurred between July 10 and August 22, and attackers attempted extortion in late September. The activity has been tied to the Clop group exploiting CVE-2025-61884, and impacted individuals are being offered 12 months of identity protection and advised to consider credit freezes.

🔐 Password managers centralize credentials but are attractive targets for attackers who exploit phishing, malware, vendor breaches, fake apps and software vulnerabilities. Recent incidents — including a 2022 LastPass compromise and an ESET‑reported North Korean campaign — demonstrate how adversaries can exfiltrate vault data or trick users into surrendering master passwords. To reduce risk, use a long unique master passphrase, enable 2FA, keep software and browsers updated, install reputable endpoint security, and only download official apps from trusted stores.

🔔 Synnovis has begun notifying its NHS customers and affected data controllers about the volume of patient information compromised in a June 2024 ransomware attack. The incident, attributed to a Qilin affiliate, saw roughly 400GB of data published and caused widespread disruption to blood services, cancelled appointments and at least one reported death. Synnovis said notifications will be completed by 21 November, citing the 'exceptional scale and complexity' of an unstructured and fragmented dataset, a delay that has drawn sharp criticism from security experts.

🔒 GlobalLogic has notified 10,471 current and former employees that their data was exposed after a zero-day in Oracle E-Business Suite (EBS) was exploited in early October 2025. The company says it patched the vulnerability after confirming data exfiltration on 9 October.
