This analysis details infrastructure used by multiple Russian cyber espionage clusters targeting academia, think tanks, and organizations in Europe and the United States. The clusters UNC6293, UNC7005, and UNC5976 employ OAuth phishing, Microsoft device code phishing, and WhatsApp targeting techniques. UNC6293 uses sophisticated lure domains impersonating reputable organizations with possible Evilginx configurations. UNC7005 shows lower operational security with simpler phishing domains. UNC5976 uses Google Drive impersonation for OAuth phishing. The investigation uses DNS data, CSS hashes, favicon analysis, registration patterns, and certificate info to track and identify related malicious infrastructure.

RecruitTrap is a sophisticated phishing campaign targeting enterprise credentials by impersonating HR personnel from well-known companies. It uses Browser-in-the-Browser techniques on desktop and full-screen fake login pages on mobile without visible URL indicators. The campaign actively screens victims to focus on corporate accounts, rejecting personal emails. Attackers impersonate multiple global brands and use persistent hosting on Amazon and SEDO networks. Detection of malicious domains is significantly delayed by traditional threat feeds. The campaign facilitates credential harvesting, OAuth token theft, and lateral movement within organizations.

A path traversal vulnerability affecting the Windows version of WinRAR allows the attackers to execute arbitrary code by crafting malicious archive files. This vulnerability was exploited in the wild and was discovered by Anton Cherepanov, Peter Košinár, and Peter Strýček from ESET.

Educational institutions continue to be the most targeted sector globally, experiencing an average of 4,696 weekly cyberattacks per organization between January and July 2026, representing an 8% increase year-over-year and more than double the cross-industry average. The back-to-school period sees intensified malicious activity, with July 2026 recording 4,848 weekly attacks. Threat actors are registering thousands of education-themed domains, with one in every 226 newly registered domains being malicious. APAC leads with 7,452 weekly attacks, while Europe and Latin America show the fastest growth at 18% and 42% respectively. Attackers deploy phishing campaigns impersonating retailers, schools, and Microsoft 365 to steal credentials and financial information from students, educators, and families during peak enrollment periods.

Jewelbug is a China-based threat actor conducting dual operations: espionage campaigns targeting foreign governments and militaries, alongside a for-profit cryptocurrency fraud business administered from the same control panel. Operating as a small development team with role-based access controls and documented roadmaps, the group recorded over one million implant check-ins, 580,000+ stolen browser cookies, and 2,300+ exfiltrated emails between February and May 2026. Espionage attacks targeted government entities in the Middle East, Southeast Asia, and South Asia with confirmed intrusions. The group deploys the Antino backdoor, a malicious Chrome/Firefox extension called 'PDF Viewer,' and a Linux implant named ClientKing targeting servers and routers. The financially motivated arm operates as a registered Hunan company running industrial-scale SEO poisoning funneling Chinese-speaking victims to fake cryptocurrency exchange sites.

A sophisticated credential theft campaign manipulates DNS and HTTP traffic on captive portal networks at hotels, conference centers, and hospitality venues to redirect victims to attacker-controlled infrastructure. The operation harvests Microsoft 365 credentials through phishing pages, device code phishing abusing Microsoft Entra ID authentication flow, and malware delivery via ClickFix social engineering techniques. Evidence indicates compromised shared captive portal services rather than individual venue breaches, with affected gateways identified in several U.S. cities, India, and Saudi Arabia. The campaign deploys two primary malware tools: CornFlake, a Go-based RAT providing persistent access and extensive surveillance capabilities, and ChocoShell, an in-memory PowerShell stealer that harvests browser credentials, Microsoft 365 tokens, and Azure AD tokens. The operation targets travelers across multiple sectors and has expanded to include Android devices through malicious APK files.

A sophisticated scam is spreading through WhatsApp that exploits the platform's legitimate 'Linked devices' feature to take over user accounts. Attackers compromise existing accounts and send messages to contacts asking them to vote for a friend or relative in various online contests. When victims click the provided link, they are redirected through pages appearing to be WhatsApp-related, often using the legitimate wa.me domain. The attack tricks users into authorizing a new linked session, granting attackers full access to read messages, send messages as the victim, and access contacts. The scam is particularly effective because it comes from known contacts and relies on trust and quick reactions. Once compromised, attackers can continue the scam by messaging the victim's contacts, creating a chain of account takeovers without triggering traditional security alerts.

Children are targeted by a sprawling ecosystem of websites exploiting their interest in Roblox and Minecraft through offerwall reward schemes and phishing campaigns. These sites promise free in-game currency in exchange for completing tasks, collecting personal data, enrolling minors in paid subscriptions, and violating platform terms of service that can result in account bans. The infrastructure relies on cheap, disposable hosting with aggressive domain rotation. Using Internet-wide scan data from Censys, this analysis characterizes two categories: offerwall get-paid-to reward sites and credential harvesting generators. The exposed infrastructure handles children's data with minimal security, monetizing their attention at scale through affiliate commissions while presenting significant privacy and security risks.

Scam advertising campaigns have been identified that impersonate trusted brands to redirect consumers to unrelated online gambling sites. These operations utilize paid social media advertisements on platforms like Facebook, Instagram, and TikTok, combined with fake app store pages and Progressive Web Apps. The campaigns target UK consumers primarily, with variants observed in German and Spanish. Scammers impersonate major brands including financial institutions like Monzo, Revolut, and Barclays, as well as household names such as Tesco, Amazon, Netflix, and Facebook. The scheme involves three stages: paid ads claiming brands have launched official casino products, fake landing pages mimicking app stores, and PWAs that redirect to gambling sites through affiliate tracking links. Typical affiliate payouts range from $50 to $350 per depositing player, indicating significant financial motivation behind these operations.

A phishing campaign targeting Chile continues to evolve with significant infrastructure expansion. Security researchers identified 99 new domains impersonating the legitimate PasasteSinTAG portal, with 22 domains confirmed active and 77 registered but not yet activated. The active domains utilize various top-level domains including .click, .cfd, .cyou, .mom, .best, .rest, .top, .help, .sbs, .icu, .life, .xyz, .buzz, .casa, and .pics. The infrastructure is hosted across seven IP addresses. This campaign represents an ongoing threat to Chilean users through brand impersonation tactics, with threat actors maintaining a large reserve of dormant domains for future rotation.
