GhostCode Phishing Kit Bypasses Microsoft 365 MFA to Hijack Accounts in 78 Seconds

eSentire identified GhostCode, a phishing kit abusing Microsoft 365 OAuth device-code sign-in to steal tokens and take over accounts in seconds.

eSentire analysts identified GhostCode in late August, a phishing kit that uses business contact-form messages and an NDA pretext to deliver a password-protected HTML attachment leading victims to a Microsoft device-code sign-in. Victims authenticate on legitimate Microsoft pages, letting the kit obtain a Primary Refresh Token in 32 seconds and register three devices in 78 seconds, with residential proxies matching the victim's location. The kit hides its redirect with encrypted addresses, junk data, and scanner-filtering challenges, and uses GHOSTnet-linked infrastructure during device enrolment. eSentire recommends blocking device-code authentication via Conditional Access, invalidating tokens, and reviewing newly enrolled devices.

Fake AI trading agent steals crypto wallet passwords

Fake AI crypto trading agent sites deliver Needle Stealer, which replaces browser wallet extensions to steal wallet passwords, HP reports.

HP researchers tracked campaigns between April and June 2026 in which a fake AI trading agent site, tradingclaw[.]pro, distributed a Microsoft-signed OLEView executable that DLL side-loads a malicious iviewers.dll and launches Needle Stealer via process hollowing. Needle replaces one of seven browser wallet extensions, including MetaMask, Coinbase Wallet, and Phantom, to capture wallet passwords. Related campaigns used QR-code invoice phishing leading to fake OneDrive pages, Phantom Stealer sold as a penetration testing tool with VBScript-to-PowerShell steganographic loaders, and image-hidden payloads delivering XWorm, PureLogs Stealer, and Formbook; a perceptual-hash VirusTotal search found about 400 distinct rigged images.

Iranian hackers use CHOSEN BRICK Windows malware to spy on targets

Iranian state-linked hackers use CHOSEN BRICK Windows malware, spread via Telegram and WhatsApp social engineering, to spy on dissidents and journalists worldwide.

US, UK, and Dutch cyber agencies with the FBI issued a joint advisory on Iranian state-linked hackers deploying a Windows malware strain called CHOSEN BRICK against dissidents, activists, and journalists, primarily in the US, UK, and Netherlands. Attacks begin with messages on WhatsApp or Telegram impersonating trusted contacts or technical support, tricking victims into running malicious files disguised as apps such as Pictory, RunwayML, Norton Antivirus, Telegram, and KeePass. The malware persists via Registry Run keys, adds Microsoft Defender exclusions, and uses a per-victim Telegram bot for command-and-control while stealing email, Telegram and WhatsApp data, screenshots, and audio. Stolen data is exfiltrated via Telegram or cloud services like VultrObjects and StorjShare, and sometimes appears on pro-Iranian leak sites, increasing physical risk for dissidents abroad.

GhostCode Abuses Microsoft Entra Device Enrollment to Maintain Access After Token Revocation

eSentire exposes GhostCode, a device-code phishing kit that abuses Microsoft Entra device enrollment to persist even after stolen tokens are revoked.

eSentire's Threat Response Unit observed GhostCode campaigns in late August 2026, using BEC-style social engineering that impersonated procurement staff, including BJ's Wholesale Club, via Salesforce contact forms. Victims received password-protected HTML lures disguised as a FlipBook document portal, with junk-data padding, HTML comment injection, and AES-256-GCM encrypted redirects gated by anti-bot checks. The kit exploits the OAuth 2.0 device authorization grant, prompting victims to approve real Microsoft device-code sign-ins with MFA. Within 78 seconds of approval, attackers registered three Entra devices and obtained a Primary Refresh Token, so rogue device registrations persist even after session token revocation.

Google Pixel phones pwned in zero-click attacks

CISA added actively exploited zero-click Pixel modem flaw CVE-2026-58704 to its KEV catalog, giving federal agencies three days to patch.

Google disclosed CVE-2026-58704, a high-severity improper authorization flaw in Pixel phones' cellular modems that bypasses permission checks and escalates privileges with no user interaction, noting limited, targeted exploitation. CISA added it to the Known Exploited Vulnerabilities Catalog with a September 19 deadline for federal agencies. Such zero-click modem bugs are a frequent vector for commercial spyware. The Register also notes two recently KEV-listed Chromium V8 flaws, CVE-2026-85046 and CVE-2026-87491, which Proofpoint says four espionage groups chained in intrusions.

NightEagle Hackers Abuse Microsoft Dev Tunnels and GhostContainer to Breach Russian Companies

NightEagle (APT-Q-95) breached Russian firms using stolen VPN credentials, a GhostContainer Exchange backdoor, Dev Tunnels abuse, and DCSync.

Kaspersky's Securelink analysts, via Securelist, documented NightEagle (APT-Q-95) attacks on Russian companies that begin with VPN logins using stolen valid credentials from Cloudflare WARP and European infrastructure. On Exchange servers the group deployed GhostContainer, a .NET backdoor built from public components including Neo-reGeorg tunneling, CVE-2020-0688 logic, and the GhostWebShell class, controlled through Exchange web headers. The operators exposed RDP through Microsoft Dev Tunnels paired with rdp2tcp, staged tools in GitHub repositories, and exploited BlueKeep (CVE-2019-0708) to create admin accounts before running DCSync against Active Directory.
