Five Eyes warns China is recruiting officials via fake job offers

The Five Eyes intelligence agencies (US, UK, Canada, Australia, and New Zealand) issued a joint bulletin, "Safeguarding Our Secrets," warning that Chinese military intelligence officers are posing as recruiters on sites like LinkedIn, Indeed, and Upwork. Fronting as think tanks, consultancies, or HR firms, they post fake jobs such as foreign-policy or defense-analyst roles, then use the interview process to pressure targets into handing over classified or non-public information. The agencies say current and former government, military, defense-contractor, research, and journalist personnel are all in scope, with extra focus on those tied to the Indo-Pacific. The goal is harvesting privileged military, political, and economic intelligence.

Check
Brief staff in sensitive government, defense, and research roles to scrutinize unsolicited recruiter and consulting approaches, and check whether anyone has shared non-public information during one.
Affected
Current and former Five Eyes government, military, defense-contractor, policy, research, and journalist personnel with access to classified or privileged information, especially those linked to the Indo-Pacific.
Fix
Verify recruiters and employers through official channels before engaging, never discuss sensitive work in interviews, and report suspected approaches to your security team or national agency.

HVAC distributor Baker breach exposes 102,000 accounts to ShinyHunters

Baker Distributing, one of the largest US wholesalers of heating, cooling, and refrigeration equipment, has been hit by the extortion group ShinyHunters, which stole company data and posted it after the company did not pay. Breach-tracking service Have I Been Pwned has now confirmed 102,935 affected accounts; the gang originally claimed more than 260,000 stolen records pulled from Salesforce and internal SharePoint sites, including HR documents. ShinyHunters has been on a tear this year, breaking into corporate SaaS accounts by tricking IT help desks into resetting credentials. Exposed personal and business data fuels follow-on phishing aimed at Baker's customers and staff.

Check
If you work with or for Baker Distributing, check whether your email appears in Have I Been Pwned and watch inboxes for HVAC or invoice-themed phishing referencing the breach.
Affected
Baker Distributing employees, contractors, and business customers whose personal and corporate data sat in the breached Salesforce and SharePoint systems; 102,935 accounts confirmed.
Fix
Reset passwords reused with Baker accounts and enable phishing-resistant MFA. For your own org, lock down help-desk identity resets with callback verification to blunt ShinyHunters-style social engineering.

FIFA World Cup 2026 fraud wave hits fans before June 11 kickoff

With the FIFA World Cup kicking off June 11 across the US, Canada, and Mexico, the FBI and researchers at Group-IB and Fortinet warn that a large fraud operation is already running. Group-IB tracked more than 4,300 fake FIFA websites and a Chinese-speaking crew, GHOST STADIUM, that cloned the official site pixel-for-pixel, fake login and all, across 300-plus domains. Scams include bogus ticket, merchandise, and hospitality sites, fake streaming apps that hide banking malware, and betting sites that harvest passport scans for identity theft. With tickets scarce and 150 million requests filed, scammers are exploiting fans' urgency to steal logins, money, and personal data.

Check
Warn staff and remind yourself to verify any World Cup ticket, merchandise, or streaming offer, and check security logs for employee visits to lookalike FIFA domains.
Affected
Anyone buying World Cup tickets, merchandise, hospitality, or streaming access, plus job seekers; employees using work devices or accounts to shop for the tournament.
Fix
Buy only via fifa.com typed directly into the browser, avoid sponsored search results and emailed links, and block known fraudulent FIFA domains at your web gateway.

Signal phishing campaign impersonates Support to steal backup recovery keys from journalists and activists, enabling full message decryption

Security researchers are warning of a phishing campaign that impersonates Signal Support over text message to steal users' backup recovery keys, specifically targeting journalists and activists. Once an attacker obtains the recovery key, they can decrypt the victim's entire message-history backup. The campaign relies purely on social engineering - there is no flaw in Signal's cryptography - tricking targets into handing over the secret that protects their encrypted backups. The targeting of journalists and activists points to surveillance-motivated actors rather than financially-driven crime. Signal users should treat any unsolicited 'Support' contact requesting recovery keys or codes as hostile, since Signal never asks for them.

Check
Brief journalists, activists, and high-risk staff that Signal never requests backup recovery keys. Treat any 'Signal Support' text asking for keys or codes as a phishing attempt and report it.
Affected
Signal users - particularly journalists and activists targeted by surveillance-motivated actors. The attack is pure social engineering; Signal's encryption is not broken, but a handed-over recovery key decrypts all backups.
Fix
Never share Signal recovery keys or codes with anyone. Enable registration lock. For high-risk users, store recovery keys offline and verify any support contact through official Signal channels only.

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.

Storm-2949 abuses Microsoft 365 Self-Service Password Reset to hijack accounts, pivot from M365 into Azure production

Microsoft is tracking a financially motivated actor it calls Storm-2949 that abuses the Microsoft 365 Self-Service Password Reset flow to hijack high-value identities and then exfiltrate as much data as possible. The actor socially engineers IT staff and senior leaders, kicks off an SSPR reset, then poses as IT support and convinces the victim to approve the resulting MFA prompt. Once in, Storm-2949 uses Graph API and custom Python to enumerate the tenant, downloads thousands of OneDrive and SharePoint files in single actions, and pivots into Azure - VMs, Key Vaults, SQL, storage - via privileged custom RBAC roles.

Check
In Entra audit logs, find users who reset their password and within 24 hours added or had MFA removed. Pull Graph API calls enumerating users and service principals from new IPs.
Affected
Microsoft 365 tenants with SSPR enabled where help-desk identity is not strongly authenticated. High-privilege custom Azure RBAC roles assigned broadly amplify blast radius.
Fix
Require ticket-based identity verification for SSPR resets on admin and exec accounts. Enforce phishing-resistant FIDO2 MFA. Tighten custom-role assignments. Alert on mass OneDrive downloads via Defender for Cloud.

SHub Reaper macOS infostealer spoofs Apple, Google, and Microsoft in one chain - backdoor, wallet hijack, document theft

SentinelOne has documented a new variant of the SHub macOS infostealer family called Reaper. Victims are lured through fake WeChat and Miro installers hosted on typo-squatted Microsoft domains, then prompted to run what looks like an Apple security update. Reaper avoids macOS Tahoe's new Terminal protections by routing its commands through the applescript:// URL scheme. Once running, it steals browser credentials, crypto wallets, dev configs, iCloud data, and Telegram sessions, replaces legitimate Exodus, Ledger, and Trezor wallet apps with backdoored copies, and installs a persistent fake Google Software Update LaunchAgent that gives the attacker an ongoing remote shell. Files larger than 85MB are uploaded in 70MB chunks.

Check
Hunt macOS endpoints for LaunchAgents named com.google.keystone.agent.plist that point at unsigned scripts in ~/Library/Application Support/Google/GoogleUpdate.app/, and search proxy logs for traffic to hebsbsbzjsjshduxbs.xyz.
Affected
macOS users who can be social-engineered into running an installer or AppleScript prompt outside the App Store. Heavily targets developer, finance, and crypto-holding personas.
Fix
Remove the malicious LaunchAgent and persistence script. Rotate all credentials in the browser keychain, crypto wallets, iCloud, Telegram, and any tokens in shell history or .gitconfig. Enforce MDM blocking unsigned LaunchAgents.

Initial access broker KongTuke pivots from web lures to Microsoft Teams - impersonates IT help desk, drops ModeloRAT in five minutes

ReliaQuest researchers say initial access broker KongTuke has shifted from web-based ClickFix and FileFix lures to Microsoft Teams social engineering, taking as little as five minutes to gain persistent access. The attacker reaches employees from one of five rotating Microsoft 365 tenants, uses Unicode whitespace tricks to make the display name look like internal IT help desk, then talks the victim through pasting a PowerShell command. That command downloads a ZIP from Dropbox containing a portable WinPython runtime and a Python-based RAT called ModeloRAT. The new ModeloRAT variant adds a five-server C2 pool with automatic failover, self-update, and randomized URL paths, and several major EDR products did not detect it.

Check
Search Microsoft 365 audit logs for inbound external Teams chats from new or low-trust tenants, hunt endpoint telemetry for pythonw.exe running from %APPDATA%\WPy64-31401 (or similar WinPython paths), and review PowerShell logs for clipboard-paste-driven commands.
Affected
Any enterprise that accepts inbound Microsoft Teams chats and calls from external tenants, especially help-desk-themed approaches. Initial access broker activity is typically resold to ransomware operators within days of compromise.
Fix
Restrict external Teams chat to allowlisted partners, enforce verified caller display in Teams admin, train staff that real IT never asks for a PowerShell paste, and add EDR rules for portable Python interpreters spawning from %APPDATA%.

Mac malware campaign uses Google ads and 'Apple Support' Claude.ai chats to install infostealer

Hackers are buying Google ads that look like they go to claude.ai - and they do go to a real claude.ai page. But the page is a shared Claude chat dressed up as 'Apple Support' walking users through installing Claude on a Mac. The instructions tell people to paste a command into Terminal that quietly downloads MacSync, a Mac infostealer that grabs saved browser passwords, cookies, and contents of macOS Keychain (where Mac stores logins and keys). Because both the ad and the page are real claude.ai links, there is no fake domain to spot. Researcher Berk Albayrak first reported the campaign; BleepingComputer found a second active variant.

Check
Check macOS endpoint logs for Terminal executions of curl or base64 piped to bash in the last 7 days, and review who clicked sponsored Google results for 'Claude mac download'.
Affected
macOS users who searched Google for 'Claude mac download' or similar terms and ran a Terminal command from a shared Claude.ai chat attributed to 'Apple Support'. Two payload variants seen: a MacSync infostealer that exfiltrates Keychain and browser secrets, and a polymorphic in-memory shell payload that profiles the host and delivers a second stage via osascript.
Fix
Rotate browser-saved passwords and macOS Keychain credentials for any user who may have run the malicious command. Sign out and re-authenticate browser sessions to invalidate stolen cookies. Block the indicator domains customroofingcontractors[.]com and bernasibutuwqu2[.]com at network egress. Reinforce with users that they should never install software from chat or terminal instructions - only from official vendor download pages.

Vietnamese fraudsters used Google's no-code app platform to send Facebook phishing emails that passed every spam check, then sold the stolen accounts back to victims

Guardio documented a Vietnamese-linked fraud operation that has stolen roughly 30,000 Facebook business accounts by abusing Google's AppSheet no-code platform as a phishing relay. Because the phishing emails come from noreply@appsheet.com (a real Google address), they pass SPF, DKIM, and DMARC checks that normally catch fake-Meta emails. The lures impersonate Meta Support and threaten account deletion within 24 hours unless the user 'submits an appeal.' Stolen credentials, 2FA codes, and government ID photos are exfiltrated to Telegram. The operators then sell the stolen accounts back to victims through their own recovery service.

Check
Brief every staff member who manages a Facebook business account that any email from 'noreply@appsheet.com' claiming to be Meta is hostile, regardless of how legitimate the formatting looks.
Affected
Facebook Business account owners worldwide, with 68.6% of victims based in the US. Acute risk for marketing teams, social media managers, and small business owners who manage Facebook ad accounts. Any organization using the same Facebook business account for paid ads since 2024 is in the broader target pool. Stolen accounts often hold credit card data and ad spend history.
Fix
Block emails from noreply@appsheet.com unless your organization legitimately uses Google AppSheet. Train staff that real Meta support never asks for 2FA codes via email. Enable Meta Business Manager 2FA with hardware keys (not SMS). For organizations already compromised, contact Meta Business Help directly through facebook.com - the 'recovery service' is the same operation that took the account.
