HOOK Android Trojan Adds Ransomware Overlays, Expands

🔒 Cybersecurity researchers at Zimperium zLabs have identified a new HOOK Android banking trojan variant that deploys full-screen ransomware-style overlays to extort victims. The overlay is remotely triggered via the command "ransome" and displays a warning, wallet address and amount, and can be dismissed by the attacker with "delete_ransome". An offshoot of ERMAC, the latest HOOK builds on banking malware techniques and now supports 107 remote commands, introducing transparent gesture-capture overlays, fake NFC and payment screens, and deceptive unlock prompts to harvest credentials and crypto recovery phrases.

Warlock Ransomware: Emerging Threat Targeting Services

⚠️ Warlock is a ransomware operation that emerged in 2025 and uses double extortion — encrypting systems and threatening to publish stolen data to coerce payment. The group has targeted government agencies and critical service providers across Europe, and on August 12 a cyber incident disrupted UK telecom Colt Technology Services, with an alleged auction of one million stolen documents. Security analysts link recent intrusions to exploitation of the SharePoint vulnerability CVE-2025-53770, which Microsoft says is actively exploited; Microsoft has published analysis and urges immediate patching. Recommended mitigations include enforcing multi‑factor authentication, keeping security tools and software patched, maintaining secure off‑site backups, reducing attack surface, encrypting sensitive data, and educating staff on phishing and social engineering.

Frenemies in Cybersecurity: Balancing Competition & Sharing

🤝 In a Threat Vector podcast, Michael Sikorski and Michael Daniel of the Cyber Threat Alliance discuss how competing vendors must nonetheless collaborate to counter shared threats. Daniel recalls how pooled observations during the 2017 WannaCry outbreak revealed its worm-like propagation and accelerated industry response. He emphasizes that the main obstacles to sharing are human—culture, legal risk, and lack of executive prioritization—and that concrete guardrails (antitrust-compliance statements, embargo protocols, and equal treatment) build the trust needed for timely intelligence exchange. The post cautions that as adversaries adopt AI and automation, systematic collaboration is essential.

MedusaLocker RaaS Recruits Penetration Testers Globally

🔒 MedusaLocker, a ransomware-as-a-service (RaaS) group active since 2019, has posted a dark web job advert openly recruiting penetration testers and insiders who already have direct access to corporate networks. The advert explicitly instructs applicants not to apply unless they possess network access, signalling a preference for initial access brokers and company insiders. CISA previously linked MedusaLocker to exploitation of RDP vulnerabilities, and the group’s tactic highlights the blurred line between legitimate pentesting and criminal activity. Organisations should prioritise layered defenses, authorised penetration testing, and strict controls over remote access and privileged accounts.

Muddled Libra Strike Teams: Collaborative Cybercrime

🧩 Muddled Libra is not a single organized group but a fluid collaboration of personas that form distinct strike teams with varying objectives and tradecraft. Unit 42 has identified patterns across at least seven teams, from crypto theft and extortion to IP theft and mass data harvesting. Defenders should prioritize protecting high-value data, tighten access controls, and assume evolving tactics rather than a fixed adversary profile.

Supply-chain Dependencies and the Resilience Blind Spot

🔐A DEF CON 33 panel argued that while digital tactics like misinformation and cyberattacks can disrupt systems, they rarely win wars on their own. Panelists emphasised that cyber effects tend to be temporary, whereas kinetic attacks inflict longer-lasting physical damage. Using a Taco Bell supply-chain analogy and real incidents such as Change Healthcare, the discussion urged organisations to map dependencies and build resilience to mitigate third-party risk.

US Seizes $1.09M in Bitcoin From BlackSuit Gang Takedown

💰 The US Department of Justice announced it seized US $1,091,453 in cryptocurrency linked to the Russian-operated BlackSuit ransomware group following an international takedown of servers, domains and the gang's dark web extortion site. The recovered funds derive from a 49.3120227 Bitcoin ransom payment on or about April 4, 2023; that payment was originally worth US $1,445,454.86. Law enforcement partners in the United States, United Kingdom, Canada, Germany, Ireland and France collaborated on the operation that seized four servers and nine domains on July 24, and the frozen funds were identified after repeated deposits and withdrawals that ended with an exchange freeze in January 2024.

Black Hat USA 2025: Insurers Limit Vendor Exposure

🛡️ At Black Hat USA 2025 speakers warned that high cyber-insurance premiums can reflect insurers capping exposure to specific third-party vendors rather than a direct finding of poor security in a customer’s environment. Insurers may respond to exceeded vendor thresholds by issuing prohibitively high quotes instead of declining coverage, effectively pricing some customers out. Claims data presented showed 45% of new claims in H1 2025 involved an SSL VPN lacking MFA, and Coalition reported 55% of ransomware begins at perimeter devices.
