Since late 2025, cybercriminals have been exploiting Wallpaper Engine, a popular live wallpaper application on Steam, to distribute malware through Steam Workshop. Attackers target primarily Chinese and Russian gamers by embedding malicious code within application wallpapers shared on the platform. These compromised wallpapers deliver various malware types including infostealers, backdoors, crypto miners, and ransomware. One analyzed sample dropped DarkKomet backdoor while hijacking Steam sessions to steal account credentials. The malware modifies system libraries to locate Steam installations and exfiltrate data to attacker-controlled servers. Compromised accounts are then used to upload additional malicious wallpapers. The diverse malware families suggest multiple independent hacking groups are exploiting this distribution method. Infected wallpapers received thousands of downloads before removal, with 89% of infections occurring in China.

Lookalike attacks exploit human cognitive shortcuts rather than technical vulnerabilities, designing domain names that resemble legitimate services to bypass security controls. These attacks leverage predictable patterns in how people read and process text, using techniques including homographs, typosquatting, domain embedding, and keyword association. The domain name itself embeds targeting intent, making attacks visible in DNS infrastructure before malicious activity occurs. Attackers face deliberate tradeoffs between plausibility and uniqueness, often maintaining domains in dormant states between campaigns to evade takedown. DNS provides early structural signals about attacker intent and brand targeting, though ambiguity remains inherent as legitimate services often exhibit similar patterns. Effective detection requires separating targets from imposters and understanding that domain-based analysis surfaces risk rather than definitive verdicts.

A sophisticated malware campaign exploits growing interest in artificial intelligence by distributing malicious files disguised as AI-related learning resources and technical guides. The attack employs an exceptionally complex multi-stage infection chain beginning with compressed archives containing LNK shortcuts and hidden PDF files. Through multiple layers of obfuscation involving PowerShell scripts, batch files, and AutoHotkey loaders, the campaign establishes persistent access and deploys two distinct .NET Remote Access Trojans including AsyncRAT. The intermediate scripts extensively use Simplified Chinese variable names and exhibit coding patterns suggesting AI-assisted development, with cultural references to Chinese mythology used as symbolic aliases for Windows API calls. The attack implements advanced techniques including process hollowing, reflective DLL injection, and scheduled task persistence while actively disabling Windows Defender exclusions to facilitate execution.

Multiple phishing campaigns are exploiting the FIFA World Cup 2026 event to target mobile users globally. These campaigns use typosquatting, institutional spoofing, and impersonation of major sports retailers to harvest credentials. A sophisticated recruitment fraud campaign also targets corporate Google Workspace accounts with an Adversary-in-the-Middle platform capable of bypassing MFA. Attack vectors include SMS, WhatsApp, and search engines, leveraging emotional urgency and ticket scarcity. This creates risks for enterprises as employees may access work resources via compromised personal devices.

The 2026 FIFA World Cup presents a concentrated attack surface spanning three nations, 16 cities, and billions of viewers. Cybercriminals have already launched phishing campaigns, fraudulent ticket sales, and brand impersonation schemes targeting governments, sponsors, broadcasters, transportation providers, and telecommunications companies. Financially motivated actors are exploiting tournament-related interest through credential theft and payment fraud. Hacktivist and state-aligned groups, including pro-Iranian actors like Handala and CyberAv3ngers, may conduct DDoS attacks, website defacements, or espionage operations amid heightened geopolitical tensions involving Iran, the United States, and Russia. Ransomware groups such as Qilin, DragonForce, Akira, and Play may target organizations reliant on continuous service availability. Thousands of FIFA-themed domains have been registered, many exhibiting characteristics associated with fraud campaigns. Organizations throughout the ecosystem face elevated ris...

ITScape (CVE-2026-46316) is a guest-to-host escape vulnerability in the vGIC-ITS emulation within KVM/arm64, disclosed by researcher Hyunwoo Kim. The flaw stems from a race condition in the vgic_its_invalidate_cache() function causing a double-put use-after-free, enabling host kernel code execution. Since the bug exists in in-kernel KVM rather than QEMU user-space, successful exploitation grants host kernel privileges, posing significant risk to multi-tenant ARM64 cloud environments. The vulnerability can be chained with local privilege escalation when guest root access is unavailable. Affected kernels range from commit 8201d1028caa through 13031fb6b835, when the patch was applied. Two YARA rules have been developed for detection: one targeting hardcoded constants from the proof-of-concept, another identifying behavioral patterns in privilege drop sequences.

The hospitality and travel sector experienced a dramatic surge in cyberattacks, with organizations facing an average of 2,291 weekly attacks in May 2026, representing a 24% year-over-year increase and a cumulative 122% rise since 2023. Cybercriminals registered 47,318 travel-related domains in May 2026 alone, with one in every 112 classified as malicious or suspicious. Three coordinated bulk-registration campaigns were identified, including sequential hotel-lure domains, American Express and Lloyds Travel Choice impersonations, and widespread Fora Travel brand abuse across 108 TLDs. Active phishing operations target major platforms including Booking.com, Airbnb, and Skyscanner through lookalike domains designed to harvest credentials and payment information. These attacks deliberately intensify during peak summer booking season when travelers are distracted and eager for deals, exploiting the industry's high volume of personal and financial data processing.

Threat actors are leveraging TikTok and Instagram Reels to distribute the Vidar infostealer through fake software tutorials. Two distinct campaigns use short-form videos disguised as tutorials for unlocking premium software like Spotify. The first campaign uses accounts mimicking official Windows profiles with AI-voiced clips instructing users to run PowerShell commands that download Vidar from lookalike domains. One video achieved over 100,000 views. The second campaign uses ordinary accounts posting music-backed clips that bait users in comments to receive malicious links via direct message. These campaigns exploit platform recommendation algorithms by encouraging saves and shares. Vidar is sold as a service for $300 lifetime license and harvests credentials, financial data and authentication tokens.

Threat actors are increasingly leveraging the global interest in artificial intelligence by impersonating popular AI platforms such as ChatGPT, Copilot, DeepSeek, and Claude in social engineering campaigns. These operations span phishing attacks, malvertising, and search engine optimization-driven tactics that ultimately lead to credential theft, financial fraud, or malware infections. Observed campaigns include ChatGPT-themed phishing collecting credit card data targeting South Africa, Claude-themed adversary-in-the-middle attacks harvesting credentials and access tokens, malvertising campaigns distributing Vidar stealer through fake AI plugin downloads, and fraudulent DeepSeek V4 installers on GitHub. The initial access broker Storm-3075 has been identified employing AI-themed malvertising, while the financially motivated actor Fox Tempest provides malware-signing-as-a-service to enhance payload legitimacy. These campaigns combine traditional social engineering tactics with AI branding to improve success...

A significant expansion of the Kali365 phishing-as-a-service operation has been observed, now targeting multiple platforms beyond Microsoft 365. The operator abuses OAuth 2.0 device authorization flows to bypass MFA and steal authentication tokens. Key discoveries include a live command-and-control panel infrastructure, a phishing campaign impersonating MAX Messenger (Russia's state-backed messaging platform with 110 million users) through fake prize-claim flows, and a cluster of 126 malicious hosts impersonating services including Microsoft Outlook, Okta SSO, Xerox DocuShare, Mail.ru, Yandex Disk, and Odnoklassniki. The operation demonstrates a deliberate focus on Russian consumer platforms alongside Western enterprise targets, utilizing Telegram bots for credential exfiltration and employing a multi-tenant phishing platform distributed through Telegram channels.
