VectraRAT is a previously undocumented Malware-as-a-Service platform combining a Go-based control server (VectraHub) with a native C++ Windows implant, renting from $250 monthly. The developer, operating under the handle 'Vectra' (formerly 'Nyxel'), has been active since August 2022 without prior public documentation. The platform offers hidden desktop control, keylogging, clipboard hijacking with cryptocurrency address replacement, browser credential theft, and a UAC bypass achieving elevation without user prompts. Delivered through Amadey loader and ClickFix campaigns targeting tax-themed lures, 48% of observed victims run corporate Windows editions including Windows Server 2025. Infrastructure analysis revealed exposed directories and operational panels across multiple hosting providers, with victims spanning the United States, Russia, Germany, and other nations.

Illegal online gambling infrastructure spans three distinct cybercrime categories that defenders often overlook. First, over 1.7 million Chinese-language casino domains facilitate illegal gambling and transnational money laundering, primarily operated by triad-aligned syndicates. Second, thousands of "scambling" websites target global audiences with rigged games and withdrawal fraud, using deposit bonuses to lure victims. Third, China-aligned APT groups deploy the PeckBirdy malware framework within fake casino and adult websites as command-and-control infrastructure, targeting education, government, finance and technology sectors across Asia. These operations exploit U.S. and European hosting providers through infrastructure laundering while maintaining bulletproof Asian hosting. The campaigns have escalated sharply since 2023, with PeckBirdy domains achieving zero detection rates on VirusTotal. All three types appear visually identical, creating detection challenges for security teams.

Mythic is an open-source command-and-control (C2) framework used by red teams and threat actors. Analysis found 131 unique Mythic C2 hosts exposed on the public Internet, with most using default TLS certificates. These deployments span major cloud providers and are concentrated in the US, Hong Kong, and China. Default artifacts such as TLS certificates with O=Mythic and port 7443 responses enable detection. Some clusters appear to be training environments, while isolated deployments with custom domains and advanced transport methods like Discord and steganography indicate operational use.

A previously undocumented Linux toolkit has been targeting South Korean automotive and media organizations with minimal detection since early 2025. The campaign employs a HAProxy instance called ted backdoor, compiled within the victim's existing HAProxy version 2.8.12, alongside trojanized versions of crond, agetty, atd, sshd, and polkitd. This sophisticated framework enables remote command execution, malicious script injection into web traffic, credential harvesting, and long-term surveillance. The ted backdoor uses HAProxy's native filter API and internal structures to intercept SSL-decrypted HTTP traffic while maintaining legitimate load balancing operations. Operating alongside are an SSH keylogger, a curl-based RAT with HAProxy health monitoring capabilities, and a deployment stager. The toolkit is attributed with medium confidence to DPRK APTs based on targeting patterns, simple XOR-based encryption schemes, custom substitution ciphers, and C2 infrastructure associated with APT37.

Peer2Profit and Astroproxy are bandwidth-sharing applications that recruit users to share their internet connections for payment. This bandwidth is then monetized through a commercial proxy service at significantly higher rates. The applications install through official channels with user consent, making them difficult to detect with traditional security tools. Researchers identified over 117,000 unique IPs in 72 hours, with rapid growth in residential IPs. Reverse engineering revealed the communications protocol and backconnect infrastructure managing proxy sessions. Testing showed these proxy networks can access internal network resources via DNS entries resolving to internal IPs, potentially exposing corporate assets. The scale and internal access capabilities present significant risks to organizations where employees run these applications.

A sophisticated traffic distribution system has been operating for over 14 months, using more than 12,700 structurally similar fake CAPTCHA PDFs hosted on Webflow's CDN. The operation begins with search engine optimization, where victims searching for legitimate content encounter malicious PDFs through Google searches. These documents contain fake CAPTCHA panels that route users through a custom Elixir/Phoenix traffic distribution system employing IP filtering, bot detection, and geographic targeting. The infrastructure sorts visitors and redirects qualifying traffic to three distinct endpoints: Legion Loader distribution, a TDS reseller gate, and premium-SMS subscription scams targeting Spanish-speaking users. Non-qualifying traffic is monetized through search-arbitrage advertising. The operation primarily targets English-speaking countries and has recently been surfaced by AI assistants including Google Gemini and Claude, expanding its reach beyond traditional search engines.

Analysis of 4 million dynamic malware reports reveals that 45.32% of malware samples with command-and-control activity establish direct-to-IP (D2IP) connections, bypassing DNS entirely and evading DNS-based security defenses. D2IP traffic accounts for 23.17% of all C2 connection attempts. This behavior is observed across diverse threats including Phorpiex ransomware droppers using hard-coded IP addresses, persistent data exfiltration campaigns employing obfuscated HTTP GET requests, SectopRAT targeting educational institutions with in-browser proxy capabilities, and IoT botnets like Mozi and Boatnet propagating through P2P networks. The research introduces zero trust IP (ZT-IP), a network-level enforcement approach that verifies whether outbound connection destinations were previously sanctioned by DNS responses, effectively blocking malicious D2IP communications that traditional DNS-based security controls cannot detect.

Four npm packages in the AsyncAPI namespace were compromised to distribute a multi-stage botnet loader called Miasma. The attack utilized trusted GitHub Actions publishing but originated from a poisoned source commit. Malicious code was injected into legitimate source files that execute when imported, launching a detached Node.js process to download an 8.25 MB encrypted payload from IPFS. The final payload is a sophisticated tasking framework supporting multiple command-and-control channels including REST, Nostr relays, IPFS, Ethereum smart contracts, and BitTorrent DHT. The framework establishes persistence via systemd services on Linux and fake NodeJS directories, supporting file operations, shell execution, data collection, and cross-ecosystem propagation capabilities for npm, PyPI, RubyGems, and Cargo ecosystems.

A sophisticated campaign deployed 148 malicious npm packages disguised as student web proxy applications under brands like Riverbend Tutoring and Northstar Tutoring. Published by accounts terminal3airport and eerikakirk, these packages weaponized visitor browsers into distributed denial-of-service botnets while generating advertising revenue. The applications functioned as working proxies but secretly executed mutable remote code and high-performance WebSocket traffic generators compatible with the Wisp protocol. During a critical two-week period in May 2026, active deployments launched HTTP floods generating 2GB/s aggregate traffic and control-plane attacks establishing 10,240 socket connections per second against target servers. The campaign abused npm as a content delivery network, affecting users who visited proxy instances rather than through traditional dependency infection.

A sophisticated China-aligned cyber espionage campaign targeting India's tax infrastructure was identified between May and June 2026. The operation impersonates the Income Tax Department, Ministry of Finance, exploiting the AY2026-27 ITR filing season to target corporate entities, tax professionals, chartered accountants, and taxpayers. The attack employs spear-phishing emails with malicious attachments mimicking legitimate government utilities. The multi-stage infection chain deploys DcRAT through steganographic payload concealment, fileless .NET execution, AMSI bypass, and Windows service persistence. The threat actor demonstrates operational maturity through active payload rotation achieving 0/66 detection rates, encrypted TLS-based C2 communications, and infrastructure hosted across multiple ASNs linked to China. The campaign shows overlaps with the China-nexus threat actor Silver Fox, featuring screen capture capabilities, data exfiltration, and systematic intelligence collection from high-value India...
