A deep technical analysis reveals updates to Hangro, North Korea's state VPN and mail product, operating on servers in Pyongyang and the Russian Far East. A new certificate hierarchy deployed in July 2026 differs significantly from the 2024 version, with both containing cryptographic anomalies where signatures fail verification. Investigation uncovered six network assignments in Chinese address space linked to a single registry contact associated with Silibank, plus infrastructure in Russian Far East networks designated KPOST. The service evolved from a commercial email gateway in 2001 to a certificate-bound VPN deployment issued to trade representatives through consulates. Technical evidence indicates structured infrastructure spanning North Korean, Russian, and Chinese address space, with mail systems configured for bulk transfers over intermittent connections using ten gigabyte message limits and ETRN capabilities.

An Israeli influence-for-hire company called BlackCore has been identified conducting digital manipulation campaigns across multiple countries. The company operates through a sophisticated infrastructure offering services including discourse dominance, organic engagement manipulation, and counter-operations. Researchers identified a specific campaign involving a 14-week training program delivered to Angolan government employees in early 2026, which included the creation and deployment of fake social media personas and coordinated inauthentic behavior. The operation utilized AI-generated profile pictures, fake news outlets like 'Agita News', and coordinated amplification tactics across Facebook, Instagram, and TikTok. BlackCore's promotional materials openly advertised their capabilities to conduct deceptive influence operations on behalf of government clients, demonstrating how influence-for-hire services have become accessible to state actors seeking to manipulate online discourse.

A significant supply chain attack compromised Brevo's infrastructure on September 14, 2026, affecting over 100,000 customer websites. Attackers injected malicious code into Brevo's JavaScript assets and widgets, delivering two distinct payloads: a WordPress plugin backdoor automatically installed when site administrators visited their own sites while logged in, and ClickFix overlays targeting regular visitors. The attack vector involved modification of Brevo's CDN-hosted files and creation of malicious subdomains under sendibt1.com. Evidence suggests attackers gained access to Brevo's Cloudflare account, allowing them to modify DNS records and rewrite content dynamically. The malicious activity lasted approximately four hours, from 16:05 to 20:12 UTC. Brevo's prominent clients include eBay, Louis Vuitton, Michelin, and Amnesty International, amplifying the attack's potential impact significantly.

Cybercriminals are using fake websites that mimic the legitimate Bitrefill site to defraud users. These lookalike sites appear in search engine results and use domains similar to Bitrefill's, including Punycode variants. Victims are tricked into completing checkout processes that resemble Bitrefill's, paying cryptocurrency to attacker-controlled addresses with no recovery option. The campaign uses sophisticated analytics to optimize victim conversion, indicating organized criminal activity.

The GrelosGTM cybercriminal group abuses the legitimate functionality of Google Tag Manager to compromise e-commerce websites, primarily those running Magento CMS. Since early 2020, they have injected malicious Google Tag Manager scripts that load multi-stage JavaScript payloads via WebSocket connections. The final payload is a heavily obfuscated JavaScript sniffer designed to steal payment card information during checkout through fake payment forms. Stolen data is exfiltrated to attacker-controlled servers. The campaign has affected at least seven websites across Belgium, Italy, the United Kingdom, and the United States.

Six Chrome and Firefox extensions linked through shared code, C2 infrastructure, and publishing history have been identified targeting cryptocurrency traders. Four malicious extensions steal authenticated session tokens and wallet data from Axiom Trade and Padre users, while two earlier extensions reveal a pattern of repackaging crypto trading tools. The extensions J7Tracker, VREO, and Orbit Tracker automatically retrieve user information, wallet bundles, Firebase tokens, and application state, then exfiltrate data to threat actor-controlled Vercel deployments. The campaign targets an active trading community with Axiom processing over $15 billion in volume across 650,000 wallets. The malicious code runs inside authenticated sessions, collecting localStorage, IndexedDB data, and API responses containing authentication tokens and wallet keys. Data is Base64-encoded and transmitted via browser navigation to avoid CORS restrictions, enabling account compromise and cryptocurrency theft.

In June 2026, researchers uncovered BigBear 2.0, a rebranded Evilginx2-based phishing-as-a-service framework targeting Microsoft 365 credentials globally. The operation, managed by operator 'General Boss', deployed 42 VPS nodes primarily hosted on Vultr infrastructure, utilizing the 'offy' phishlet configuration. The platform employed adversary-in-the-middle techniques with geo-matched residential proxy pools across 69 countries, real-time Telegram exfiltration, and automated cookie replay to bypass MFA. The campaign exfiltrated 5,137 credential records including 474 complete MFA-bypassed authentications, 1,032 plaintext passwords, and 4,148 session cookies, affecting 3,331 unique victim IPs across 40+ countries. The multi-user PhaaS panel was leased to at least five identified affiliate operators. Custom JavaScript injections disabled FIDO2/WebAuthn MFA while residential proxies bypassed anti-bot detection, enabling persistent access to compromised Microsoft 365 environments.

The Kimsuky threat group continues Operation GitPower campaigns utilizing malicious LNK files disguised as financial and business documents. Thirteen LNK variants collected between August 11-19, 2026, employ GitHub Personal Access Tokens (PAT) for command-and-control communications, delivering obfuscated PowerShell loaders through custom decoders. Notable evolution includes anti-analysis routines detecting virtualization tools, Pastebin as alternative C2 infrastructure, and diversified decoy formats (PDF, XLSX, PNG). Metadata analysis reveals AI-generated content using the 'opencode' AI coding agent and HeadlessChrome PDF conversion, with placeholder text remaining unreviewed. The group maintains persistence through hidden scheduled tasks masquerading as legitimate software (BitLocker, MATLAB), while hardcoded GitHub PATs enable raw content retrieval. Despite increased sophistication in evasion techniques and decoy production automation, endpoint behaviors remain detectable through behavioral correlation a...

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.

A resurgence in Node.js abuse has been observed since February 2026, targeting government departments, technology companies, and hotels. Attackers leverage the legitimate, signed node.exe binary to execute malicious JavaScript payloads, evading signature-based detection. In one intrusion at an Asian technology company, attackers downloaded the official Node.js installer after repeated payload blocks and used it to run an implant communicating with Ethereum blockchain gateways via EtherHiding techniques. The same threat actors compromised a U.S. fintech firm, deploying the Rust-based C2Looper backdoor linked to ransomware operations. Multiple attacks involved ModeloRAT, associated with initial access broker Woodgnat, connected to ransomware families including Qilin, Interlock, Rhysida, Akira, 8Base, Black Basta, and Embargo. Attackers employ ClickFix techniques for initial access and combine living-off-the-land tools with commodity malware.
