🔐 The UK’s National Cyber Security Centre (NCSC) reported 204 nationally significant incidents between September 2024 and August 2025, a 130% increase on the prior year’s 89 incidents. In total the agency received 1,727 incident tips and elevated 429 to cyber incidents requiring support, including 18 Category 2 “highly significant” events. NCSC leaders warned attackers are improving and urged businesses to harden defences and prioritise preparedness to sustain operations during attacks.

⚡This weekly recap covers high-impact incidents and emerging trends shaping enterprise risk. Significant exploitation of an Oracle E-Business Suite zero-day (CVE-2025-61882) and linked payloads reportedly affected dozens of organizations, while a GoAnywhere MFT flaw (CVE-2025-10035) enabled multi-stage intrusions by Storm-1175. Other highlights include a WhatsApp worm, npm-based phishing chains, an emerging ransomware cartel, AI abuse, and a prioritized list of critical CVEs.

⚠️ Aisuru, an IoT botnet derived from Mirai, generated a nearly 29.6 Tbps DDoS surge on Oct. 8, 2025, briefly disrupting major US ISPs and online gaming platforms. Logs show most attack traffic originated from compromised home routers, IP cameras and DVRs on networks operated by AT&T, Comcast, Verizon, T‑Mobile and Charter. TCPShield reported over 15 Tbps of junk traffic, and researchers warn Aisuru now operates as both a DDoS engine and a residential proxy network.

🛡️ GreyNoise researchers uncovered a massive RDP attack wave using more than 100,000 IP addresses across over 100 countries, which analysts link to a single large botnet targeting U.S. Remote Desktop infrastructure. The attackers used two enumeration techniques — an RD Web Access timing attack to infer valid usernames and an RDP Web Client login enumeration to guess credentials — enabling efficient compromise while reducing obvious alerts. GreyNoise published a dynamic blocklist template, microsoft-rdp-botnet-oct-25, and recommends that organizations review logs for unusual RDP access patterns and automatically block associated IPs at the network edge.

⚠️AI agents are now autonomously conducting cyberattacks, chaining reconnaissance, exploitation, persistence, and data theft at machine speed and scale. In 2025 public demonstrations—from XBOW’s mass submissions on HackerOne in June, to DARPA teams and Google’s Big Sleep in August—along with operational reports from Ukraine’s CERT and vendors, show these systems rapidly find and weaponize new flaws. Criminals have operationalized LLM-driven malware and ransomware, while tools like HexStrike‑AI, Deepseek, and Villager make automated attack chains broadly available. Defenders can also leverage AI to accelerate vulnerability research and operationalize VulnOps, continuous discovery/continuous repair, and self‑healing networks, but doing so raises serious questions about patch correctness, liability, compatibility, and vendor relationships.

⚠️ RondoDox is a large-scale botnet actively exploiting 56 n-day vulnerabilities across more than 30 device types, including DVRs, NVRs, CCTV systems, routers, and web servers. Trend Micro researchers describe the campaign as using an exploit shotgun strategy, firing numerous exploits simultaneously to maximize infection despite generating noisy activity. The actor has weaponized flaws disclosed at events such as Pwn2Own and continues to expand its arsenal, including both recent CVEs and older end-of-life vulnerabilities. Recommended defenses include applying firmware updates, replacing EoL devices, segmenting networks, and removing default credentials.

🔍 In September 2025, global cyber-attack volumes eased modestly, with organizations facing an average of 1,900 attacks per organization per week — a 4% decline from August but a 1% increase year-over-year. Beneath this apparent stabilization, ransomware activity jumped sharply (up 46%), while emerging GenAI-related data risks expanded rapidly, changing attacker tactics. The report warns that evolving techniques and heightened data exposure are creating a more complex and consequential threat environment for organizations worldwide.

🛡️ Microsoft and researchers report threat actors abusing Microsoft Teams for extortion, social engineering, and financial theft after hijacking MFA with social engineering resets. Separate campaigns use malicious .LNK files to deliver PowerShell droppers and DLL implants that establish persistent command-and-control. Analysts also link over $2 billion in 2025 crypto thefts to North Korean‑linked groups and identify AI-driven disinformation, IoT flaws, and cloud misconfigurations as multiplying risk. Defenders are urged to harden identity, secure endpoints and apps, patch exposed services, and limit long-lived cloud credentials.

📈 TransUnion's H2 2025 update warns that rising digital fraud is costing firms an average of 7.7% of annual revenue, amounting to an estimated $534bn in global losses. US businesses reported heavier impacts — 9.8% of revenue, or roughly $114bn — driven by a surge in account takeover and synthetic identity fraud. The report urges firms to move beyond reactive defenses and strengthen identity verification across digital touchpoints.

💰 North Korea-linked hackers have stolen more than $2 billion in cryptocurrency so far in 2025, according to blockchain analysis firm Elliptic. The total is the highest annual haul on record and is driven largely by a February $1.46bn theft from exchange Bybit. Elliptic attributes over 30 separate hacks this year and warns attackers are increasingly using social engineering and sophisticated laundering to hide proceeds.

⚠️ AI agents are increasingly automating cyberattacks, performing reconnaissance, exploitation, and data theft at machine speed and scale. In 2023 examples include XBOW's mass vulnerability reports, DARPA teams finding dozens of flaws in hours, and reports of adversaries using Claude and HexStrike-AI to orchestrate ransomware and persistent intrusions. This shift threatens accelerated attacks beyond traditional patch cycles while presenting new defensive opportunities such as AI-assisted vulnerability discovery, VulnOps, and even self-healing networks.

🔒 Ransomware now inflicts costs far beyond ransom payments, driving operational downtime, reputational damage, and regulatory exposure that directly erode the bottom line. The 2025 Unit 42 report shows median initial extortion demands rose to $1.25M and commonly equate to about 2% of perceived annual revenue. While roughly 48% of victims paid in 2024, Unit 42 negotiation reduced median paid demands to about 0.6% of PAR, yet attackers’ disruptive tactics increasingly amplify recovery costs. Strengthening backups, segmentation, and an incremental zero trust posture are key to limiting impact and shortening recovery timelines.

🛡️ Trellix researchers detail the return of XWorm 6.0, a modular Windows malware now supporting more than 35 in‑memory DLL plugins and expanded data-theft and persistence capabilities. The actor associated with earlier releases, known as XCoder, is of uncertain status, but v6.0—advertised on forums in June 2025—appears to address a prior RCE flaw while enabling credential theft, keylogging, screen capture, and optional ransomware. Campaigns use phishing, malicious JavaScript, LNK-based PowerShell chains, and process injection to evade detection and execute plugins directly in memory.

📰 Recorded Future assesses that the Beijing Institute of Electronics Technology and Application (BIETA) is likely directed by China's Ministry of State Security, citing links between at least four BIETA personnel and MSS officers and ties to the University of International Relations. Its subsidiary Beijing Sanxin Times Technology Co., Ltd. (CIII) develops steganography, covert-communications tools, and network-penetration and simulation software. The report warns these capabilities can support intelligence, counterintelligence, military, and other state-aligned cyber operations.

🔔 From unpatched vehicles to hijacked clouds, this ThreatsDay bulletin outlines active threats and defensive moves across endpoints, cloud, browsers, and vehicles. Observers reported internet-wide scans exploiting PAN-OS GlobalProtect (CVE-2024-3400) and campaigns that use weak MS‑SQL credentials to deploy XiebroC2 for persistent access. New AirBorne CarPlay/iAP2 flaws can chain to take over Apple CarPlay in some cases without user interaction, while attackers quietly poison browser preferences to sideload malicious extensions. On defence, Google announced AI-driven ransomware detection for Drive and Microsoft plans an Edge revocation feature to curb sideloaded threats.

📧 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.

📣 The EU security agency's ENISA Threat Landscape 2025 report, analyzing 4,875 incidents from 1 July 2024 to 30 June 2025, finds phishing was the initial access vector in 60% of intrusions, with vulnerability exploitation at 21%. Botnets and malicious applications accounted for 10% and 8% respectively, and 68% of intrusions led to follow-up malware deployment. ENISA highlights AI-powered phishing exceeded 80% of social engineering globally by early 2025 and warns of attacks aimed at critical digital supply chain dependencies and high-value targets such as outdated mobile and OT systems.

🔎 Researchers at Palo Alto Networks have attributed two years of coordinated espionage to a previously unreported Chinese-aligned threat actor dubbed Phantom Taurus. The group targets government and telecommunications organizations across Africa, the Middle East, and Asia, focusing on foreign ministries, embassies, geopolitical events and military operations to maintain persistent covert access. Its toolkit includes a new IIS web-server backdoor suite called NET-STAR, DNS- and remote-access tools, in-memory implants and a wide mix of dual-use utilities. Operators have shifted from Exchange mailbox harvesting via ProxyLogon and ProxyShell exploits to targeted SQL database searches and WMI-driven data extraction.

🔐 Fortinet’s 2025 Global Threat Landscape Report underscores that two fundamentals — protecting against phishing and keeping software up to date — remain the most effective defenses. Attackers are scaling campaigns with automation and generative AI to produce more convincing messages, and they combine email, SMS, and voice techniques to raise success rates. Organizations should strengthen employee training, deploy MFA, and adopt centralized or automated patch management to reduce exposure and limit lateral movement.

🔍 The 2025 Unit 42 Global Incident Response Report shows that 84% of investigated incidents involved activity across multiple attack fronts and 70% spanned at least three vectors, underscoring coordinated, multidomain campaigns. Attackers move laterally across cloud, SaaS, IT and OT, exploiting identities, misconfigurations and vulnerabilities. The report recommends unified telemetry, AI-driven behavioral analytics and stronger identity controls to improve detection and accelerate response.
