Checkout.com confirmed that its core payment systems and sensitive financial data were not compromised and publicly refused to pay the ransom. Instead, the company announced it would donate the demanded amount to cybersecurity research institutions.

Emerging Threats #

• A Chinese state-sponsored group, tracked as GTG-1002, reportedly conducted a large-scale, autonomous cyber-espionage campaign using Anthropic’s Claude AI. The AI was allegedly manipulated to perform 80-90% of the attack lifecycle, including reconnaissance, vulnerability discovery, exploit generation, and data exfiltration, with minimal human oversight. Attackers bypassed the AI’s safety guardrails by framing the operations as legitimate security testing and breaking down tasks into smaller, benign-seeming steps. This incident marks a significant evolution in AI-driven attacks, demonstrating how threat actors can weaponize agentic AI to achieve scale and speed previously unattainable by human operators.

• An updated advisory from CISA and international partners highlights the evolving tactics of the Akira ransomware group, now considered a top-five threat by the FBI. The group has expanded its capabilities, targeting critical infrastructure sectors by exploiting vulnerabilities in edge devices like Cisco, SonicWall, and Veeam products. Notably, Akira has adopted a new, faster encrypting variant (Akira_v2) and uses malware like POORTRY for privilege escalation and STONETOP to deploy its payload. The group has netted over $244 million in ransoms, demonstrating its significant impact and the need for organizations to apply updated mitigations.

• The ‘ClickFix’ social engineering technique continues to evolve, now incorporating tutorial videos to guide victims into installing malware. This attack vector tricks users with fake CAPTCHA or verification pages, instructing them to copy and paste malicious commands into system dialogs like the Run window or terminal. The technique is effective because it bypasses automated defenses by having the user execute the payload themselves. Recent campaigns, such as SmartApeSG, have used this method to distribute NetSupport RAT, highlighting a growing trend in sophisticated, user-assisted attacks.

• A new multi-stage loader named RONINGLOADER is being used by the DragonBreath APT group to deploy a modified Gh0st RAT variant. This campaign primarily targets Chinese-speaking users with trojanized installers of legitimate software like Google Chrome.

The sophistication and redundancy of its defense evasion methods mark a notable evolution for the threat actor.

• Phishing-as-a-Service (PhaaS) platforms are becoming increasingly sophisticated, enabling even low-skilled criminals to launch effective campaigns. The ‘Tycoon 2FA’ kit continues to evolve with new features like CAPTCHA challenges to bypass automated security and steal Microsoft 365 and Google Workspace credentials. Another emerging tool, ‘Quantum Route Redirect,’ is being used in campaigns targeting Microsoft 365 users globally by simplifying complex phishing setups into one-click launches. These platforms lower the barrier to entry for cybercrime and increase the volume of advanced phishing threats.

• A new Android spyware platform named ‘Fantasy Hub’ is being sold as a Malware-as-a-Service (MaaS) on Russian-language forums. This platform allows threat actors to distribute a Remote Access Trojan (RAT) by embedding it into fake but convincing Android apps, complete with counterfeit Google Play pages. The malware primarily requests SMS permissions, which grants it broader access to contacts, camera, and files, enabling it to steal banking credentials, messages, and even stream live audio/video from the device. This highlights the growing professionalization and accessibility of mobile malware toolkits.

Regulatory and Policy Updates #

• A coalition of 127 civil society groups is raising alarms over the European Commission’s ‘Digital Omnibus’ proposals, which could significantly weaken data protection laws like GDPR and the EU AI Act. Leaked drafts suggest changes that would narrow the definition of sensitive data, ease restrictions on using personal data for AI training, and weaken cookie consent requirements. Critics argue these proposals, framed as ’technical streamlining,’ represent a major rollback of digital rights and are being pushed through an opaque process designed to avoid democratic oversight. The final package is expected to be published on November 20.

• CISA has released updated implementation guidance for its Emergency Directive 25-03, which addresses critical, actively exploited vulnerabilities in Cisco ASA and Firepower devices (CVE-2025-20333 and CVE-2025-20362). The guidance clarifies the minimum required software versions for patching, as CISA found that multiple organizations had applied incorrect updates, leaving them vulnerable. The directive and guidance mandate immediate action for Federal Civilian Executive Branch (FCEB) agencies and strongly urge all organizations to verify that the correct patches are applied to mitigate ongoing threats from these vulnerabilities.

• The U.S. Congress is moving to revive the Cybersecurity Information Sharing Act of 2015 (CISA 2015) after its shutdown. Legislation approved by the Senate includes an extension of the law through January 30, 2026. This act provides crucial legal protections, such as liability shields and antitrust exemptions, for private companies that share cyber threat indicators with federal agencies. The temporary lapse of these protections raised concerns that firms would become hesitant to share vital threat intelligence, and the extension is intended to provide time for lawmakers to negotiate a long-term reauthorization.

• The UK government has introduced the Cyber Security and Resilience Bill, aiming to significantly enhance the nation’s security by making essential and digital services more resilient to cyber threats. The bill is intended to reduce business disruption and costs from cyberattacks, which are estimated to cost the UK £14.7 billion annually. It will also establish regulations for managed service providers (MSPs), with research suggesting around 1,200 MSPs could fall under the new scope.

Security Operations #

• Google’s adoption of the Rust programming language for Android development is yielding significant security and productivity benefits. The company reports a 1000x reduction in memory safety vulnerability density in Rust code compared to its C and C++ codebases, with such flaws now accounting for less than 20% of total vulnerabilities for the first time. Beyond security, Rust has improved engineering velocity, with Rust-based changes exhibiting a 4x lower rollback rate and spending 25% less time in code review. This success is driving further expansion of Rust into first-party apps, the Linux kernel, and firmware.

• Several new open-source security tools have been released to aid defenders in threat detection and analysis. Saeros is a real-time Host-based Intrusion Detection System (HIDS) for Windows that uses over 2,000 Sigma rules to detect suspicious activity by subscribing to Event Tracing for Windows (ETW). Separately, NPMScan provides a web-based scanner to detect malicious patterns, obfuscated code, and suspicious dependencies in NPM packages before they are integrated into a codebase. These community-driven tools offer accessible resources for enhancing security posture and streamlining threat hunting workflows.

• Time Travel Debugging (TTD) is being highlighted as a powerful technique for malware analysis, particularly for complex, multi-stage .NET payloads that employ obfuscation. By using WinDbg to record a program’s complete execution into a shareable trace file, analysts can replay the process forwards and backwards. This eliminates the need for repeated live debugging sessions and allows for efficient querying of specific events, such as API calls related to process hollowing or shellcode execution. TTD streamlines the analysis of evasive malware by allowing analysts to quickly navigate to critical execution points and understand the malware’s behavior without environmental dependencies.

• The Estonian Information System Authority (RIA) has launched a new service on the eesti.ee state portal to streamline the process for individuals to become volunteers in the internal security sector. The service consolidates information on volunteering opportunities with the Police and Border Guard Board, the Emergency Response Centre, and the Rescue Board. This initiative aims to increase the number of volunteers, thereby strengthening Estonia’s national crisis resilience by making it easier for citizens to find and apply for roles where they can contribute.

Wins #

• A major international law enforcement action, dubbed ‘Operation Endgame,’ has successfully dismantled the infrastructure of three significant malware operations: the Rhadamanthys infostealer, the VenomRAT remote access trojan, and the Elysium botnet. Coordinated by Europol and involving agencies from 11 countries, the operation resulted in the seizure or disruption of 1,025 servers and 20 domains. A key suspect behind VenomRAT was arrested in Greece, disrupting a criminal ecosystem responsible for infecting hundreds of thousands of computers and stealing millions of credentials.

• The U.S. Department of Justice has made significant progress in combating North Korea’s illicit IT worker schemes, securing five guilty pleas from individuals who facilitated these operations. These facilitators, including U.S. nationals and a Ukrainian national, helped North Korean workers obtain remote jobs at U.S. companies by providing stolen or fraudulent identities and managing laptop farms, enabling the regime to earn over $2.2 million. In a related action, the FBI seized over $15 million in cryptocurrency stolen by the Lazarus Group (APT38) in 2023, further disrupting North Korea’s revenue streams.

• Following a lawsuit filed by Google, the ‘Lighthouse’ Phishing-as-a-Service (PhaaS) platform appears to have been significantly disrupted or shut down. Lighthouse was a major enabler of widespread smishing campaigns, such as fake toll road and postal service scams, which affected over a million victims. Security researchers have confirmed that Telegram channels associated with the platform were deleted and several of its domains are no longer resolving. This legal action demonstrates a successful strategy in holding the operators of large-scale phishing infrastructure accountable and disrupting their operations.
