Dental-benefits provider DentaQuest added to Have I Been Pwned with 2,553,599 breached accounts; healthcare-themed phishing risk

Have I Been Pwned has added US dental-benefits provider DentaQuest to its breach corpus with 2,553,599 unique email addresses. DentaQuest is one of the largest dental and vision benefits administrators in the United States, serving Medicaid, Medicare, and commercial members. As is typical for HIBP additions, the underlying breach source and disclosure details are not published alongside the entry, but the listing lets individuals and organizations check whether their accounts appear in the leaked dataset. Healthcare and insurance data carries elevated risk: affected members should anticipate benefits-themed phishing, claim-status lures, and identity-theft attempts, and should rotate any reused passwords. It is among the larger US healthcare-adjacent breaches surfacing recently.

Check
Check whether your @company emails appear in HIBP's DentaQuest corpus. Warn affected staff about dental/medical-benefits-themed phishing - claim status, coverage updates, refund lures - over the next 60-90 days.
Affected
2,553,599 unique email addresses tied to DentaQuest dental and vision benefits members (Medicaid, Medicare, commercial). Healthcare data elevates identity-theft and benefits-phishing risk.
Fix
Affected individuals: rotate DentaQuest passwords and any reused elsewhere, enable MFA, monitor benefits statements. Organizations: add DentaQuest to breach-monitoring watchlists and brief staff on healthcare-themed social engineering.

Dashlane confirms attackers downloaded encrypted vaults of fewer than 20 users in brute-force campaign; Master Password still protects data

Dashlane has updated its brute-force-attack disclosure with a material escalation: attackers successfully downloaded a copy of the encrypted vaults belonging to fewer than 20 personal-plan users. The campaign aimed to break two-factor authentication and register new devices on existing accounts; the high volume of attempts triggered the temporary suspensions reported earlier. Dashlane says it directly notified each affected user and that anyone who did not receive a vault-risk message is unaffected. Crucially, vault data cannot be decrypted without the Master Password, so unless a password is trivial and predictable, cracking attempts are unlikely to succeed. Dashlane's internal systems were not compromised. Users should review registered devices and enable 2FA.

Check
If your team uses Dashlane, confirm whether anyone received a vault-risk notification. For notified users, treat the encrypted vault as exposed and rotate all stored credentials promptly.
Affected
Fewer than 20 Dashlane personal-plan users whose encrypted vaults were downloaded. Vaults are useless without the Master Password; weak or predictable Master Passwords are the residual risk.
Fix
Notified users: rotate every stored credential and change the Master Password to a long, unique one. All users: review registered devices, remove unknown ones, and enable 2FA.

Automotive marketplace Edmunds added to Have I Been Pwned with 177,860 breached accounts; expect car-buying-themed phishing

Have I Been Pwned has added the US automotive marketplace Edmunds to its breach corpus with 177,860 unique email addresses. Edmunds is a widely used car-research and shopping platform offering pricing, reviews, and dealer listings. As is typical for HIBP additions, the underlying breach source and disclosure details are not published alongside the entry, but the listing lets individuals and organizations check whether their accounts appear in the leaked dataset. Affected users should anticipate car-buying-themed phishing such as financing offers, dealer-contact lures, or vehicle-quote follow-ups, and should rotate any reused passwords. The addition continues a steady run of mid-size US consumer-platform breaches surfacing in HIBP.

Check
Check whether your @company emails appear in HIBP's Edmunds corpus. Warn affected staff about car-buying-themed phishing (financing offers, dealer contacts) over the next 30-60 days.
Affected
177,860 unique email addresses tied to Edmunds accounts. Reused passwords are the primary downstream risk; expect automotive-themed phishing and credential-stuffing against other services.
Fix
Affected individuals: rotate Edmunds passwords and any reused elsewhere, enable MFA. Organizations: add Edmunds to breach-monitoring watchlists and brief staff on car-shopping-themed social engineering.

ShinyHunters publishes Charter Communications data after failed extortion - up to 5 million customer records now leaked, not just claimed

The ShinyHunters extortion group has now published the Charter Communications data it stole, after the telecom giant apparently refused to pay. Earlier reporting put the breach at 4.9 million HIBP-confirmed unique accounts; ShinyHunters' leak is described as potentially impacting up to 5 million customers. Charter is one of the largest US telecoms, providing internet, cable, mobile, and phone services to residential and business customers under the Spectrum brand. The data was originally exfiltrated via voice-phishing of a Microsoft Entra account on April 1 and a Salesforce export. With the data now public rather than merely claimed, the phishing and identity-theft risk to affected customers rises sharply.

Check
If you are a Charter/Spectrum customer or vendor, treat the leaked dataset as public now. Watch for Spectrum-themed phishing and account-recovery fraud over the next 60-90 days.
Affected
Up to 5 million Charter/Spectrum customers whose records are now publicly leaked, not just claimed. Names, contact details, and plan information enable targeted phishing and impersonation.
Fix
Affected individuals: rotate Spectrum credentials, enable MFA, scrutinize unsolicited Charter contacts. Organizations: refresh breach-monitoring watchlists and brief help desks against Charter-themed social engineering.

ShinyHunters Charter Communications breach hit 4.9 million unique accounts (42M records claimed) - HIBP confirms scale

HIBP has confirmed 4.9 million unique accounts (4,851,517 email addresses) were affected by the Charter Communications breach disclosed earlier this week. The ShinyHunters extortion gang initially claimed 42 million records exfiltrated from Charter's Salesforce instance via voice-phishing of a Microsoft Entra account on April 1; the unique-account count is lower because individuals appeared on multiple records (customer + business + plan-info). Charter publicly denies that CPNI (Customer Proprietary Network Information) or sensitive personal data was taken. The HIBP entry refines the scope to a defender-actionable figure and lets customers and IR teams check exposure across their workforce.

Check
Run your @company.com domains against HIBP for Charter exposure. If you are a Charter customer or vendor, expect targeted vishing themed around Spectrum service issues for the next 60 days.
Affected
4.9 million unique Charter/Spectrum customer email addresses now in HIBP. SaaS-extortion playbook (Salesforce + Entra/Okta SSO + BPO vishing) remains the broader risk pattern.
Fix
Affected individuals: rotate Spectrum credentials, enable MFA, scrutinize unsolicited Charter calls. Organizations with Salesforce + Entra: enforce phishing-resistant MFA on all admin and BPO identities.

Carnival Corporation confirms breach affecting 5,995,277 customers - April 10 social-engineering of employee account, ShinyHunters claimed

Carnival Corporation, the world's largest cruise-line operator with 90+ ships across Carnival, Princess, Holland America, Costa, P&O, Cunard, AIDA, and Seabourn, has confirmed a breach affecting 5,995,277 customers. The intrusion began April 10 when an employee was social-engineered into giving up account credentials; Carnival's IT team detected the unauthorized activity on April 14. ShinyHunters claimed responsibility in April and listed the company on its data leak site. Carnival served around 13.5 million guests in 2024 across its fleet. The company is now notifying affected individuals. The pattern aligns with the broader ShinyHunters SaaS-extortion playbook documented across Charter, Instructure, and others over the past quarter.

Check
If your @company.com domains include former Carnival, Princess, Holland America, Cunard, AIDA, or Seabourn customers, prepare for targeted phishing themed around bookings, refunds, and loyalty programs.
Affected
5,995,277 Carnival customers across nine cruise brands. Initial access via social-engineering an employee account on April 10. Same ShinyHunters playbook as Charter and Instructure.
Fix
Enforce phishing-resistant MFA across cruise/hospitality estate. Train front-line staff against social-engineering for account credentials. Audit Salesforce/Entra exports for bulk-data signals.

Fake 'UK Visa Portal' third-party (Active Leadgen LLC) exposed 100,000 passports and selfies on public AWS S3

TechCrunch has flagged a public AWS S3 bucket operated by a UAE-registered third-party site, UK Visa Portal (Active Leadgen LLC), that exposed at least 100,000 passport scans and selfies belonging to people who paid extra to apply for UK electronic travel authorizations. The site is not the official GOV.UK service; users could complete the same application directly on GOV.UK in minutes for free. The third party reportedly responded with legal threats instead of remediation. The dataset is now in the wild and creates substantial identity-document compromise risk - passport scans plus selfies enable KYC bypass against banks, exchanges, and government services.

Check
Brief staff that 'UK Visa Portal' and similar third-party visa-help sites are not GOV.UK and may leak documents. Anyone who uploaded a passport to ukvisaportal.com should treat it as compromised.
Affected
100,000+ individuals (and counting) who used Active Leadgen LLC's UK Visa Portal site. Passport scans plus selfies enable KYC bypass against banks, exchanges, and government services.
Fix
Affected individuals: report passport as potentially compromised; consider replacement. Banks/exchanges: tighten document-plus-liveness verification against AI-generated impersonations using leaked identity documents.

Insurance provider Kemper added to Have I Been Pwned with 269,299 breached accounts; new financial-services dataset searchable

Have I Been Pwned has added US insurance provider Kemper to its breach corpus with 269,299 unique email addresses. Kemper offers auto, home, life, and health insurance across the United States. As is typical for HIBP additions, the underlying breach source and disclosure details are not published alongside the entry, but the listing lets individuals and organizations check whether their accounts appear in the leaked dataset. Affected customers should anticipate insurance-themed phishing - claim-status updates, policy-renewal prompts, or premium-refund lures. The addition continues a steady run of US financial-services and insurance breaches surfacing in HIBP through late May.

Check
Check whether your @corp emails appear in HIBP's Kemper corpus. Warn affected staff and customers about insurance-themed phishing (claims, renewals, refunds) over the next 30-60 days.
Affected
269,299 unique email addresses tied to Kemper insurance accounts (auto, home, life, health). Customers are exposed to targeted insurance-themed social engineering.
Fix
Affected individuals: rotate Kemper passwords, enable MFA, scrutinize unsolicited insurance communications. Organizations: add Kemper to breach-monitoring watchlists and brief help desks on potential impersonation.

Charter Communications confirms ShinyHunters breach: 40M records via vishing-compromised Microsoft Entra employee account and Salesforce export

US broadband giant Charter Communications has confirmed a data breach after the ShinyHunters extortion group listed it on its Tor leak site claiming 40 million stolen consumer and business records. ShinyHunters told BleepingComputer the intrusion began April 1 via a vishing attack that compromised an employee's Microsoft Entra account, used to export records from the company's Salesforce instance. Stolen data reportedly includes names, email addresses, addresses, phone numbers, plan information, and some CPNI (Customer Proprietary Network Information). Charter publicly denies CPNI was taken. ShinyHunters' SaaS-extortion playbook continues: Salesforce + Entra/Okta SSO + BPO vishing is the same model used against Instructure and others.

Check
Audit Microsoft Entra and Salesforce admin sign-ins for unusual IPs and large record exports around April 1, 2026. Search service-account activity for bulk data pulls.
Affected
Charter Communications/Spectrum customers (consumer and business). ShinyHunters claims 40M records exfiltrated via vishing of an Entra account. Broader: any org with Salesforce + Entra/Okta SSO + BPO support.
Fix
Enforce phishing-resistant MFA on every Entra account, especially help-desk and BPO identities. Apply Salesforce Shield Event Monitoring to alert on bulk exports. Train BPO/help-desk staff against vishing.

Lithuania investigates theft of 600,000 state registry records; opposition leader alleges Russian intelligence; Centre of Registers chief resigns

Lithuanian authorities are investigating the theft of around 600,000 records from the country's Centre of Registers, which holds state registry data. The breach was detected in early April and disclosed publicly only after weeks of internal investigation. Centre of Registers chief Adrijus Jusas resigned Monday, citing years of underinvestment that would need ~€60 million to address. The leader of Lithuania's conservative opposition alleges 'hallmarks of a Russian intelligence operation' and warns the data (including residential addresses linked to sensitive government personnel) could enable surveillance, phishing, and sabotage planning. Lithuanian prosecutors have neither confirmed nor denied Russian involvement.

Check
If your organization has Lithuanian operations or staff with state registry records, treat residential addresses and personal identifiers as compromised. Monitor for targeted phishing and impersonation.
Affected
Lithuanian citizens and residents whose data is held by the Centre of Registers. Sensitive government personnel are at heightened risk per the opposition leader's warning about surveillance use.
Fix
Lithuanian operations: update access credentials per government guidance. Watch for spear-phishing using residential-address pretexts. NATO/EU defenders: assume similar Eastern European registries are next given the precedent.
