Hudson Rock and other researchers validated the dataset, noting impacts across many industries and countries, and urged affected organizations to rotate credentials and enforce MFA.

🔒 Oxford University disclosed a data breach after its third-party provider, Group GTI, reported that the CareerConnect platform was compromised on May 28. The attackers accessed users' first and last names, email addresses, and encrypted passwords for accounts not using Single Sign-On; GTI has invalidated those passwords and will require resets. The university said no course materials, uploaded files, appointments, or financial data appear affected, but warned users to watch for phishing attempts.

🛡️ FortiGuard Labs warns that cybercriminals are actively exploiting FIFA World Cup 2026 demand, registering thousands of themed domains and creating fake ticketing sites, malicious apps, and impersonation accounts to steal credentials and payments. Their research found over 13,000 new tournament-related domains and identified numerous scams across social media, underground forums, and stealer telemetry. Organizations and fans are urged to prepare early and verify official channels.

🛡️ McAfee researchers report that a large-scale malware campaign named WeedHack has infected more than 116,000 systems by distributing malicious Minecraft mods, clients, cheats, and utilities via YouTube links and SEO poisoning. The operation provides a free, clear-net MaaS dashboard and a paid premium tier that adds remote control, keylogging, and webcam access, targeting session IDs, browsers, wallets, and gaming credentials. Victims are concentrated in the US, Germany, India, and the UK, and the campaign uses hundreds of distribution URLs and thousands of malicious JARs. Players are urged to only download from official sources and use the in-game Marketplace for safety.

🔒 A Romanian national was sentenced to 56 months in federal prison after pleading guilty to aggravated identity theft and unauthorized access to an Oregon state government computer network. The 46-year-old, known online as "inthematrixl," also sold access and stolen personal data from other U.S. victims, causing at least $250,000 in losses. Authorities coordinated internationally to arrest and extradite him, and the court ordered forfeiture of cryptocurrency and supervised release.

📧 Recent phishing campaigns exploit Google’s AppSheet platform to send convincing emails from a legitimate noreply{@}appsheet.com address, making them likely to bypass filters. Attackers craft personalized messages — urgent warnings or enticing job offers — to trick victims into submitting identity details on clone sites, then harvest credentials and data. The compromises can lead to account takeover, device control, and secondary targeted attacks using the stolen information.

🔒 Subscription services are widespread and often contain personal data, making them attractive targets for attackers. The article outlines common attack vectors — phishing, credential reuse, infostealers, and bulk-resale of hacked family slots — and explains practical defenses: use password managers, enable two-factor authentication or passkeys, and monitor active sessions. It also advises how to spot phishing and track hidden recurring charges through bank statements and app-store settings.

🐛 PCPJack is a new worm that targets exposed cloud infrastructure to harvest credentials while actively removing traces of rival group TeamPCP. It infects Linux systems via a shell script (bootstrap.sh), establishes persistence (monitor.py), and propagates by scanning for exposed Docker, Kubernetes, Redis, MongoDB and RayML services. Stolen credentials are encrypted with X25519/ChaCha20-Poly1305 and exfiltrated to Telegram channels; researchers recommend MFA, IMDSv2 and least-privilege controls.

🔒 A phishing campaign abused Google sponsored search results to deliver a live adversary-in-the-middle (AitM) proxy that mimics ManageWP's sign-in page, placing the fake result above the legitimate one for the "managewp" query. Any credentials entered are exfiltrated to a Telegram channel and used in real time to bypass 2FA. Guardio Labs infiltrated the attackers' C2, observed an operator-driven phishing framework, and confirmed around 200 unique victims.

🔐 A Vietnamese-linked operation used a Google AppSheet address as a phishing relay to distribute credential-harvesting pages and compromise roughly 30,000 Facebook accounts. Guardio, calling the scheme AccountDumpling, says stolen accounts are resold via an illicit storefront after exfiltration to Telegram channels. Lures hosted on Netlify, Vercel and Google Drive, plus Canva-generated PDFs, were used to harvest passwords, 2FA codes, IDs and business data, leaving many victims locked out.

🔍 Flare researchers examined a recent forum post in which a threat actor details a structured OPSEC framework aimed at sustaining high-volume carding operations while avoiding detection. The actor prescribes a three-tier architecture—public, operational, and extraction layers—with strict identity compartmentalization, residential IP rotation, and isolated cashout channels. The post highlights recurring failures like identity reuse, metadata leakage, and weak anti-fingerprinting, and recommends resilience measures such as time-delayed triggers and dead man's switches. For defenders, it underscores the need to link cross-platform identities, evolve behavioral detection, and monitor the full attack chain.

🔒 Arctic Wolf attributes a large-scale spear-phishing campaign to BlueNoroff, a subgroup of the Lazarus Group, which targeted more than 100 cryptocurrency and fintech organizations across 20+ countries. The operation used typosquatted Zoom and Microsoft Teams links, manipulated Calendly invites, fake meeting interfaces and ClickFix-style clipboard injection to harvest credentials and wallet data. Researchers observed a self-sustaining deepfake pipeline, PowerShell-based C2, AES-encrypted browser payloads and Telegram-based exfiltration, with some intrusions persisting for 66 days.

🛡️Scammers are creating convincing fake tax authority websites worldwide to harvest credentials, steal personal data, and distribute malware embedded in downloaded “documents.” These portals also run fraudulent paid services that collect taxpayer identifiers and financial details for later abuse. Cryptocurrency holders are specifically targeted with fake verification flows that request seed phrases or wallet connections, leading to immediate theft. Kaspersky cautions against using cloud-hosted AI for tax preparation and recommends sticking to verified official channels, encrypting sensitive files, and employing reputable security tools.

🛡️ Security researchers at Socket and StepSecurity have identified malicious versions of pgserve and automagik published to the npm registry that execute a credential-harvesting payload during installation. The trojans collect tokens, SSH keys, cloud credentials (AWS, Azure, GCP), browser passwords and crypto wallet funds, and attempt to propagate by using any npm publish tokens found on infected machines. Stolen data is encrypted and exfiltrated to a decentralized ICP canister, chosen specifically to resist takedown. Developers are urged to rotate all credentials immediately, disable automatic postinstall scripts (npm config set ignore-scripts true), harden CI/CD egress and tighten token scopes.
