Attacker Breakout Time Drops to 18 Minutes, ReliaQuest

🔒 ReliaQuest's Threat Spotlight (June–August 2025) reports average attacker breakout time — the period from initial access to lateral movement — has fallen to 18 minutes, with one Akira incident taking just six minutes. The vendor warns adversaries are becoming faster and more adept at bypassing endpoint protections, noting an increase in ransomware using the SMB protocol (from 20% to 29%). Drive-by compromise was the leading initial vector at 34%, and USB-based malware, notably Gamarue, is resurging due to weak policy enforcement and inconsistent endpoint controls.

Jaguar Land Rover Extends Production Pause After Cyberattack

🚗 Jaguar Land Rover has extended a production shutdown until Wednesday 1 October 2025 after a major cyber incident that halted its Solihull, Halewood and Wolverhampton plants. The company said teams are working with cybersecurity specialists, the NCSC and law enforcement while it investigates, and warned the outage has already cost an estimated £120m in profits and £1.7bn in revenue. Unions have called for government-backed support for suppliers facing bankruptcy amid cascading supply-chain risk.

Ransomware Attack Disrupts Check-in at Major EU Airports

🛫 Over the weekend several major European airports experienced check-in and boarding disruptions after a ransomware attack on the external vendor Collins Aerospace. Attackers targeted the MUSE multi-airline check-in system, forcing manual processing of thousands of passengers and causing delays and cancellations to more than 100 flights. Airports affected included Heathrow, Brussels and Berlin Brandenburg, with only minor impact reported in Cork and Dublin. Authorities and the vendor are investigating while restoration efforts continue.

Experts Urge Updated Defenses Against Scattered Spider

🔐 Organizations should urgently update defenses to counter the Scattered Spider collective, experts warned at the Gartner Security & Risk Management Summit 2025. The group used social engineering, helpdesk vishing, and push notification fatigue to bypass MFA and abuse SSO, compromising accounts like Okta and stealing tokens from LastPass. Firms are advised to implement stronger identity protections, number-matching MFA, stricter password-reset procedures, and tighter third-party vendor monitoring to reduce exposure.

Weekly Recap: Chrome 0-day, AI Threats, and Supply Chain Risk

🔒 This week's recap highlights rapid attacker innovation and urgent remediation: Google patched an actively exploited Chrome zero-day (CVE-2025-10585), while researchers demonstrated a DDR5 RowHammer variant that undermines TRR protections. Dual-use AI tooling and model namespace reuse risks surfaced alongside widespread supply-chain and phishing disruptions. Defenders should prioritize patching, harden model dependencies, and monitor for stealthy loaders.

Researchers Find GPT-4-Powered MalTerminal Malware

🛡️ SentinelOne researchers disclosed MalTerminal, a Windows binary that integrates OpenAI GPT-4 via a deprecated chat completions API to dynamically generate either ransomware or a reverse shell. The sample, presented at LABScon 2025 and accompanied by Python scripts and a defensive utility called FalconShield, appears to be an early — possibly pre-November 2023 — example of LLM-embedded malware. There is no evidence it was deployed in the wild, suggesting a proof-of-concept or red-team tool. The finding highlights operational risks as LLMs are embedded into offensive tooling and phishing chains.

Fortra patches critical GoAnywhere MFT deserialization bug

⚠ Users of GoAnywhere MFT are urged to install an urgent patch for a critical insecure deserialization vulnerability tracked as CVE-2025-10035, rated CVSS 10. The flaw resides in the License Servlet and can allow an attacker with access to the Admin Console to submit a forged license response that deserializes an arbitrary, actor-controlled object, enabling remote command execution. Fortra released fixes in versions 7.8.4 and 7.6.3 and advises customers not to expose the Admin Console directly to the internet. The issue closely mirrors a 2023 vulnerability that was widely exploited by ransomware groups, elevating the risk of rapid exploitation.

SystemBC Powers REM Proxy, Compromising ~1,500 VPS

🛡️ Lumen Technologies' Black Lotus Labs reports that SystemBC, a C-based SOCKS5 proxy malware, powers roughly 80% of the REM Proxy network and averages about 1,500 compromised hosts per day. The botnet operates through more than 80 C2 servers and mainly targets VPS instances from major commercial providers, often via dropped shell scripts that install the proxy implant. REM Proxy also advertises pools of compromised Mikrotik routers and open proxies and has been used by actors tied to TransferLoader and the Morpheus ransomware group.

Ransomware Still Evades Defenses Despite Protections

🔒 Picus Security's Blue Report 2025 shows ransomware continues to outpace defenses: overall prevention fell from 69% to 62% year-over-year, while data exfiltration prevention collapsed to just 3%. Both established families (BlackByte, BabLock, Maori) and emerging strains (FAUST, Valak, Magniber) bypass controls using credential theft, fileless techniques and staged execution. Picus recommends continuous Breach and Attack Simulation (BAS) to validate controls, deliver actionable fixes, and provide measurable evidence of readiness.

Ransomware Extortion Claim Targets BMW Group Servers

🔒 The BMW Group has been named on the darknet by the Everest ransomware group, which claims to have stolen critical BMW audit documents, according to screenshots reported by Cybernews. The gang placed two countdown timers on its onion site—one running to Sept. 14 and a second giving BMW 48 hours to make contact. BMW has not commented and the extortionists have not confirmed whether customer or personal data were taken; Cybernews researcher Aras Nazarovas advises waiting for a published sample to assess the scope.

HybridPetya ransomware bypasses Windows Secure Boot

🔒 Researchers at ESET have identified a new bootkit-style ransomware named HybridPetya that targets the NTFS Master File Table (MFT) and can override UEFI Secure Boot to install a malicious EFI component. The malware abuses a patched vulnerability (CVE-2024-7344) in a signed Microsoft EFI file to load an unsigned payload called cloak.dat. The installer replaces the Windows bootloader, triggers a crash and, on reboot, the compromised loader executes a bootkit that encrypts the disk with Salsa20, using a fake CHKDSK message to conceal activity. ESET observed a ransom demand of €850 in Bitcoin but regards the sample as likely a research proof-of-concept.

UK Arrests Two Teens Linked to Scattered Spider Hacks

🔒 UK law enforcement has arrested two teenagers allegedly tied to the Scattered Spider hacking group over an August 2024 cyberattack on Transport for London (TfL). Nineteen-year-old Thalha Jubair and 18-year-old Owen Flowers were detained; authorities say Jubair faces U.S. charges for dozens of intrusions, extortion and money laundering while Flowers faces additional charges linked to U.S. healthcare targets. Prosecutors allege the group extorted at least $115 million in ransoms and that law enforcement previously seized roughly $36 million in cryptocurrency tied to Jubair.

Smart Cities Face Growing Cybersecurity Risks and Gaps

🏙️ Smart cities are expanding rapidly—69% of municipalities report strategic agendas and an estimated 83,000 sensors were deployed in 2024—significantly enlarging the attack surface. High-profile incidents (Dallas alarm hack, Washington, DC ransomware, Florida water-treatment manipulation, and Olsztyn transport disruption) show that networked devices can lead to both digital and physical harm. Experts from Accenture, Zebra Technologies, and S2GRUPO warn that legacy devices, fragmented governance, and IT/OT convergence demand zero-trust, segmentation, and coordinated incident response to reduce systemic risk.

US and UK Charge Two Suspects in Scattered Spider Attacks

🔒 US and UK authorities have charged two UK-based teenagers linked to the Scattered Spider cybercrime group in connection with multiple high-profile intrusions. Thalha Jubair, 19, and Owen Flowers, 18, face US and UK charges including conspiracy to commit computer fraud, wire fraud, money laundering and offences under the UK Computer Misuse Act. Authorities allege extensive social engineering, ransomware extortion and transfers of victim cryptocurrency, with investigators attributing at least $115m in ransom payments to the group. The arrests follow a multinational probe and earlier detentions of other alleged members.

🔒 The New York Blood Center (NYBCe) confirmed that an unauthorized party accessed internal systems between January 20 and January 26, 2025, and copied files containing personal and health information for nearly 194,000 individuals. Compromised data includes names, Social Security numbers, driver's license or state ID numbers, bank account details for direct deposit, and health/test records. NYBCe says it moved quickly to contain the incident, is offering free identity protection through Experian, and has set up a call line for potentially affected people.

SystemBC Turns Compromised VPS into High-Capacity Proxy

🔎 Researchers at Lumen Technology’s Black Lotus Labs say the SystemBC proxy botnet actively targets commercial VPS instances worldwide to build a high-capacity proxy network. The operation averages about 1,500 bots daily, relies on more than 80 C2 servers, and primarily exploits unpatched systems that often contain dozens of vulnerabilities. Customers and operators exhibit poor operational security, and the service is used by ransomware groups and third-party proxy resellers.

SonicWall Urges Password Resets After Backup Files Exposure

🔒 SonicWall is urging customers to reset credentials after detecting suspicious activity that exposed firewall configuration backup files stored in MySonicWall cloud for under 5% of users. Although stored credentials were encrypted, the preference files contained information that could help attackers exploit related firewalls; the company says this was a series of brute-force accesses, not a ransomware event. Customers should verify backups, disable remote management and VPN access, reset passwords and TOTPs, review logs, and import the provided randomized preferences file that resets local passwords, TOTP bindings, and IPSec keys.
