Tomorrowland Belgium 2026, spanning two weekends in July at De Schorre in Boom, sold out rapidly, creating opportunities for cybercriminals. Investigation uncovered approximately a dozen fraudulent websites impersonating the festival brand to target ticket seekers and travellers. These scams include fake ticket shops mimicking official sales with countdown timers and fraudulent biometric checks, travel sites offering bogus accommodation and transport packages, and affiliate schemes. The operations harvest complete identity data, payment credentials, and personal information through sophisticated social engineering. Victims lose money with no recourse, face identity theft risks, and ultimately receive invalid or non-existent tickets. The scammers exploit high demand, tight supply, and rushed purchasing decisions, with sites registered weeks in advance and pushed hardest when official tickets are sold out.

A sophisticated phishing campaign impersonates DocuSign's branding to compromise victims through malicious JavaScript embedded in fraudulent webpages. The attack leverages social engineering to trick users into downloading MSI installers disguised as legitimate DocuSign updates or documents. These payloads establish remote access through legitimate Remote Monitoring and Management tools from Atera Network Ltd and ConnectWise/ScreenConnect. Investigation revealed extensive attacker infrastructure spanning hundreds of domains, with tracking mechanisms via Telegram bots collecting detailed victim telemetry including IP addresses, geolocation, ISP information, and user-agent strings. The campaign targets both Windows and macOS systems, utilizing deployment kits across multiple infrastructures with similar URL patterns and JavaScript mechanisms.

Cybercriminals are conducting phishing campaigns by hosting malicious pages on Vercel, a legitimate website hosting platform. The attack involves sending phishing emails with links to fake Adobe PDF viewer pages that prompt users to download executable files disguised as documents. The malware, distributed as Invoice06092025.exe.bin, automatically installs LogMeIn remote access software upon execution, enabling attackers to remotely control compromised machines. Over a two-month period, more than 28 distinct campaigns have been observed targeting over 1,271 users. The attackers leverage trusted platforms to disguise their malicious activity, making detection more challenging and increasing the likelihood of successful compromise.

RedHook is an Android Remote Access Trojan that has re-emerged with significant enhancements, particularly in privilege abuse capabilities. The malware autonomously exploits Android's ADB Wireless Debugging features to obtain shell-level access, integrating the Shizuku framework to execute protected system APIs. Recent activity shows expansion beyond Vietnam to Indonesia, targeting Southeast Asian users through spoofed government and financial websites. Malicious APKs are hosted on trusted platforms like AWS S3 and GitHub repositories. The current version supports 53 distinct server-issued commands and employs sophisticated persistence mechanisms including foreground activity spoofing, silent media playback, and cross-process monitoring. Distribution relies on social engineering via phone calls and messaging applications, tricking victims into downloading malicious APKs and enabling Accessibility services under false pretenses.

Vidar, a Malware-as-a-Service infostealer first identified in 2018, continues to be distributed through phishing campaigns targeting Korea in the first half of 2026. The threat actor uses phishing emails disguised as job applications and copyright infringement notices, with attachments appearing as Word documents but actually being executables. Vidar employs a Go-based packer, uses Dead Drop Resolver technique via Telegram and Steam profiles to obtain C&C addresses, and implements anti-debugging and anti-VM techniques. The infostealer exfiltrates sensitive information including browser credentials, cookies, browsing history, cryptocurrency wallet data, Discord tokens, Telegram information, Steam data, Azure credentials, and screenshots. Configuration information is downloaded in JSON format, and data collection is performed based on received flags and additional downloaded conditions.

A sophisticated multi-stage phishing campaign delivers a previously undocumented framework called Avalon through spoofed legal documents hosted on Proton Drive. The intrusion begins with password-protected archives containing ISO images that execute malicious MSBuild projects, loading payloads entirely in memory without conventional executable attachments. Avalon consolidates credential theft, lateral movement, recovery disruption, and ransomware capabilities within a single framework, with its encryption component branded as CrownX. The framework demonstrates hallmarks of AI-assisted development, rapidly combining multiple post-exploitation capabilities that previously required sustained development effort. Avalon targets browsers, cryptocurrency wallets, messaging platforms, VPN configurations, and infrastructure systems while implementing extensive defense evasion techniques against major security products. The framework disrupts recovery by eliminating Volume Shadow Copies, Windows Recovery Environment...

In May 2026, an attack campaign targeting banking users in Spain and Portugal was identified involving the Ousaban banking Trojan. The malware, previously active in Brazil, spreads through phishing PDFs that redirect victims to malicious webpages performing environment checks to ensure targets are located in Spain or Portugal. The attack chain involves VBS scripts downloading steganographic images containing the payload, which is then dropped and executed on victims' systems. Ousaban establishes persistence, monitors banking activity across multiple financial institutions, and uses daily-changing DDNS domains to resolve C2 server addresses. The malware employs screenshot capture, keylogging, clipboard injection, and remote control capabilities to steal banking credentials. It utilizes custom encryption algorithms and geofencing techniques to evade detection and limit exposure to intended targets.

With the introduction of charges/taxes on certain items posted from outside the EU, threat actors appear to be leveraging the situation to send fraudulent SMS and email messages impersonating postal services in an attempt to harvest payment details and personal information. The campaign is already being observed targeting Irish users, and I'd like to highlight this activity publicly as part of a LinkedIn post around our Brand Protection, Threat Intelligence, and Domain Takedown capabilities.

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.

A global phishing campaign targets business functions with emails carrying malicious Excel attachments that initiate a multi-stage infection chain when macros are enabled. The attack uses layered obfuscation, including HTA scripts, PowerShell, encoded payloads, and steganography in PNG files, to deliver and execute Remote Access Trojans such as Remcos and AsyncRAT in a largely fileless manner. It achieves scale and persistence through high variability, automation, disposable infrastructure, and consistent patterns that help evade detection despite relatively simple techniques.
