🔍 Cisco Talos warns a Chinese‑speaking threat group tracked as UAT-8099 is actively compromising misconfigured Microsoft IIS servers to run SEO fraud and harvest high-value data. The actors favor high-reputation domains in universities, technology firms, and telecom providers across India, Thailand, Vietnam, Canada and Brazil to reduce detection. They exploit unrestricted file uploads to install web shells, escalate a guest account to admin, enable RDP and deploy the BadIIS SEO malware, then persist with hidden accounts and VPN/backdoor tools. Talos has published indicators and mitigation guidance, including blocking script execution in upload folders, disabling RDP and enabling MFA.

🛡️ Infoblox links a threat actor dubbed Detour Dog to campaigns distributing the Strela Stealer, using compromised WordPress sites to host first-stage backdoors such as StarFish.

🔒 Oracle said some customers received extortion emails tied to its E-Business Suite and linked the campaign to vulnerabilities patched in the July 2025 Critical Patch Update. While Oracle did not attribute the activity to a specific ransomware group, its investigation found potential use of previously identified EBS flaws, including three that were remotely exploitable. Security firms reported executives began receiving ransom demands on or before September 29, 2025. Oracle urged customers to apply the latest patches and contact support if they need assistance.

⚠️ Trend Micro has uncovered a self-propagating malware campaign named SORVEPOTEL that primarily targets Brazilian Windows users via WhatsApp. The attack is delivered through convincing phishing messages with malicious ZIP attachments that contain LNK shortcuts which trigger PowerShell to download a batch payload. The payload establishes persistence by copying itself to the Windows Startup folder and contacts a command-and-control server, and if WhatsApp Web is active the malware automatically forwards the infected ZIP to contacts and groups, causing rapid spread and frequent account bans. Researchers report no evidence of data exfiltration or file encryption so far.

🚨 BI.ZONE warns of a campaign dubbed Cavalry Werewolf that has targeted Russian state agencies and critical industrial sectors using FoalShell and StallionRAT. Attackers used spear-phishing with spoofed Kyrgyz government emails and RAR attachments to deploy lightweight reverse shells and a RAT that exfiltrates data via a Telegram bot. Observed tooling and Telegram commands indicate organized post-compromise operations and use of socks proxies for lateral movement. BI.ZONE links the activity to groups including Tomiris and YoroTrooper, suggesting possible Kazakhstan ties.

🛫 WestJet has confirmed a data breach affecting 1.2 million customers following a June 13, 2025 intrusion, and notified authorities on September 29. The airline says a "sophisticated, criminal third party" accessed names, contact details, reservation documents and other relationship data; WestJet Rewards members may have had IDs and points balances exposed, though account passwords were not accessed. WestJet states that credit card numbers, expiry dates and CVVs were not compromised, systems are secure, affected customers are being contacted, and identity protection is being offered where appropriate.

🔒 Researchers at Halcyon, Google, and Mandiant report an extortion campaign attributed to actors likely affiliated with the Cl0p gang, targeting Oracle E‑Business Suite (EBS) via exposed local login pages. Attackers allegedly abused the AppsLocalLogin.jsp password‑reset workflow to obtain local credentials that bypass SSO and often lack MFA, then sent executive extortion demands with proof samples. Demands range into seven and eight figures, reportedly up to $50 million; defenders are advised to restrict public EBS access, enforce MFA, and review logs immediately.

🔐 Cisco Talos recently disclosed activity by a Chinese-speaking cybercrime group tracked as UAT-8099 that compromises legitimate Internet Information Services (IIS) web servers across several countries. The actors use automation, custom malware and persistence techniques to manipulate search results for profit and to exfiltrate sensitive data such as credentials and certificates. Talos notes the group maintains long-term access and actively protects compromised hosts from rival attackers. Organizations should hunt for signs of BadIIS, unauthorized web shells and anomalous RDP/VPN activity and share IOCs promptly.

📧 An individual or group claiming to work with the Clop ransomware gang has been sending extortion emails to executives at multiple organizations since September 29, according to Google. Researchers at Mandiant and the Google Threat Intelligence Group are investigating and report a high-volume campaign launched from hundreds of compromised accounts, with at least one account previously linked to FIN11. The messages include contact information that matches addresses on the Clop data leak site, suggesting the actor may be leveraging Clop's brand; however, investigators emphasize this does not prove direct Clop involvement and advise targeted organizations to search for indicators of compromise.

🔒 Fortinet researchers attribute a renewed phishing campaign to Confucius, which has repeatedly targeted Pakistani government, military, and defense industry recipients using spear‑phishing and malicious documents. Attack chains observed from December 2024 through August 2025 delivered WooperStealer via DLL side‑loading using .PPSX and .LNK lures, and later introduced a Python implant, Anondoor. The group layered obfuscation and swapped tools and infrastructure to sustain credential theft, screenshot capture, file enumeration, and persistent exfiltration while evading detection.

⚠️ Cybersecurity researchers flagged a malicious PyPI package named soopsocks that claimed to provide a SOCKS5 proxy while delivering stealthy backdoor functionality on Windows. The package, uploaded by user 'soodalpie' on September 26, 2025, had 2,653 downloads before removal and used VBScript or an executable (_AUTORUN.VBS/_AUTORUN.EXE) to bootstrap additional payloads. Analysts at JFrog reported the executable is a compiled Go binary that runs PowerShell, adjusts firewall rules, elevates privileges, performs reconnaissance and exfiltrates data to a hard-coded Discord webhook.

📧 Google Mandiant and the Google Threat Intelligence Group report a new high-volume extortion campaign that claims stolen data from Oracle E-Business Suite. The operation began on or before September 29, 2025, uses hundreds of compromised accounts, and includes contact addresses verified on the Cl0p data leak site. Mandiant notes at least one sending account has ties to FIN11, a TA505 subset. Investigations are ongoing and organizations are urged to inspect for compromise.

🔒 Two newly identified Android spyware campaigns, dubbed ProSpy and ToSpy, impersonate Signal and ToTok to trick users into installing malicious APKs masquerading as a Signal encryption plugin or a Pro ToTok build. The malware requests standard messenger permissions and exfiltrates contacts, SMS, media, app lists and ToTok backups. ESET found distribution via cloned websites and noted persistence techniques to survive reboots. Users in the UAE appear to be targeted; download apps only from official stores or publishers and keep Play Protect enabled.
