And another XWorm[1] wave in the wild! This malware family is not new and heavily spread but delivery techniques always evolve and deserve to be described to show you how threat actors can be imaginative! This time, we are facing another piece of multi-technology malware.
Multiple phishing campaigns were identified using workplace meeting lures, PDF attachments, and abuse of legitimate binaries to deliver signed malware. The attacks used digitally signed executables masquerading as legitimate software to install remote monitoring and management (RMM) tools like ScreenConnect, Tactical RMM, and Mesh Agent. These tools enabled attackers to establish persistence and move laterally within compromised environments. The malware was signed using an Extended Validation certificate issued to TrustConnect Software PTY LTD. The campaigns demonstrate how familiar branding and trusted digital signatures can be exploited to bypass user suspicion and gain an initial foothold in enterprise networks.
Check Point Research has identified a Chinese-nexus advanced persistent threat group named Silver Dragon, targeting organizations in Southeast Asia and Europe since mid-2024. The group, likely operating under APT41, exploits public-facing servers and uses phishing emails for initial access. They deploy custom tools including GearDoor, a backdoor using Google Drive for command and control, SSHcmd for remote access, and SilverScreen for covert screen monitoring. Silver Dragon primarily focuses on government entities, utilizing Cobalt Strike beacons and DNS tunneling for communication. The group's sophisticated tactics and evolving toolkit demonstrate a well-resourced and adaptable threat actor.
Key Findings Introduction In recent months, Check Point Research (CPR) has been tracking a sophisticated, Chinese-aligned threat group whose activity demonstrates operational correlation with campaigns previously associated with APT41. We have designated this activity cluster as Silver Dragon. This group actively targets organizations in Southeast Asia and Europe, with a particular focus on government entities.

A week-long automated attack campaign targeted CI/CD pipelines across major open source repositories, achieving remote code execution in multiple targets. The attacker, an autonomous bot called hackerbot-claw, used five different exploitation techniques and successfully exfiltrated a GitHub token with write permissions from one of the most popular repositories on GitHub. The campaign targeted repositories belonging to Microsoft, DataDog, CNCF, and other popular open source projects. The attacks included token theft via poisoned Go scripts, direct script injection, branch name injection, filename injection, and AI prompt injection. The most severe attack resulted in a full repository compromise of Aqua Security's Trivy project. The campaign highlights the growing threat of AI-powered bots targeting software supply chains and the need for automated security controls in CI/CD pipelines.
This article analyzes real-world instances of indirect prompt injection (IDPI) attacks targeting AI agents and large language models integrated into web systems. The researchers identify 22 distinct techniques used by attackers to embed malicious prompts in webpages, including visual concealment, obfuscation, and dynamic execution methods. They categorize attacker intents ranging from low-severity disruptions to critical data destruction attempts. Notable findings include the first observed case of AI-based ad review evasion and attempts at search engine optimization manipulation. The article presents a taxonomy of web-based IDPI attacks and provides insights into attack trends based on telemetry data. The researchers emphasize the need for proactive, web-scale defenses to detect IDPI and distinguish between benign and malicious prompts.
A malicious SMS spoofing campaign is spreading a fake version of Israel's 'Red Alert' emergency app amid ongoing conflict. The trojanized Android app, disguised as a trusted warning platform, can steal SMS, contacts, and location data while appearing legitimate. The campaign exploits public fear during crises to deploy mobile spyware. The malware uses sophisticated techniques to bypass security checks, including package manager hooking and dynamic payload loading. It mirrors the official app's interface but requests high-risk permissions. The malware continuously tracks GPS coordinates and exfiltrates data to attacker-controlled infrastructure, posing severe strategic and physical security risks. This campaign erodes trust in emergency response systems and could potentially be used for targeted attacks or to optimize missile targeting.
A newly announced quantum algorithm suggests that the practical decryption of RSA encryption using quantum computers could occur much sooner than previously anticipated. Traditionally, the threat to RSA and ECC encryption from quantum computing was linked to Shor’s algorithm, which requires million-qubit quantum computers, a technology not expected in the near term. This new development challenges that assumption, indicating that the quantum breaking point for widely used public key cryptography may be closer. Although no known exploits exist in the wild yet, this advancement raises significant concerns for the security of current cryptographic systems. Organizations relying on RSA and ECC for confidentiality and integrity should begin preparing for a post-quantum cryptographic transition. The threat impacts global communications, financial transactions, and data protection mechanisms. Immediate mitigation involves accelerating the adoption of quantum-resistant algorithms and increasing cryptographic agility. Countries with advanced technological infrastructure and heavy reliance on RSA/ECC encryption are at higher risk. The overall severity is assessed as high due to the potential widespread impact and the fundamental nature of the cryptographic break, despite the current lack of active exploitation.

A significant joint offensive by the US and Israel has triggered a multi-vector retaliatory campaign from Iran, leading to an escalation in cyberattacks. Iran's limited internet connectivity is likely hindering state-aligned threat actors' ability to coordinate sophisticated attacks. Hacktivist groups are targeting perceived adversaries, while other nation-state actors may exploit the situation. Observed activities include phishing campaigns, DDoS attacks, data exfiltration, and wiper attacks. Multiple Iranian state-aligned personas and collectives have claimed responsibility for various disruptive operations. Pro-Russian hacktivist groups have also been active, targeting Israeli systems and infrastructure. The situation remains fluid, and organizations are advised to implement multi-layered defenses and focus on foundational security hygiene.
Microsoft has discovered phishing campaigns exploiting OAuth's redirection mechanisms to bypass conventional defenses. Attackers create malicious applications with redirect URIs pointing to malicious domains, then distribute phishing links prompting targets to authenticate. The attack abuses OAuth's error handling to redirect users from trusted providers to attacker-controlled sites for phishing or malware delivery. Campaigns targeted government and public sectors using e-signature, financial, and political lures. Some attacks led to malware downloads and endpoint compromise via PowerShell and DLL side-loading. Mitigation involves governing OAuth apps, limiting user consent, reviewing permissions, and implementing cross-domain detection across email, identity, and endpoint.
The report details the resurgence of the Funnull cybercriminal group, now utilizing a new arsenal called RingH23. It exposes their tactics, including compromising GoEdge CDN nodes, poisoning the MacCMS supply chain, and deploying sophisticated malware components like Badredis2s, Badnginx2s, and Badhide2s. The group has expanded its operations to inject malicious JavaScript, hijack cryptocurrency transactions, and redirect traffic to fraudulent sites. The campaign's impact is estimated to affect millions of users daily. The report also highlights Funnull's use of a suspicious new CDN infrastructure, CDN1.AI, likely created to evade detection.
