🔎 Security researchers observed a large surge in network scans probing Cisco ASA login portals and Cisco IOS Telnet/SSH endpoints, with GreyNoise recording two major spikes in late August 2025. The second wave on August 26, 2025, was largely (about 80%) driven by a Brazilian botnet using roughly 17,000 IPs and overlapping Chrome-like user agents that suggest a common origin. Administrators are urged to apply the latest patches, enforce MFA for remote ASA logins, avoid exposing management pages and services directly, and use VPN concentrators, reverse proxies, geo-blocking, and rate limiting to reduce risk.

🔒Cisco Talos Incident Response (Talos IR) analyzed pre-ransomware engagements from January 2023 through June 2025 to determine which controls most often prevented ransomware deployment. Rapid engagement with incident responders and near-immediate action on EDR/MDR alerts were the two strongest correlates of stopping encryption. Talos found that aggressive blocking and quarantine settings, strict identity and privilege controls, improved logging, and early notifications from partners materially increased the chance of eviction before encryption. The guidance focuses on securing remote services, credential protection, application allowlisting, and network segmentation.

📰 This week’s Threat Source newsletter highlights three significant vulnerabilities Talos researchers uncovered and helped remediate: a Dell firmware persistence flaw (Revault), an Office for macOS permissions bypass, and router compromises that blend malicious traffic with legitimate ISP flows. The author, William Largent, also emphasizes mental health and recommends a paper on AI behavioral pathologies to help anticipate malicious or errant AI-driven activity. Top headlines include a 4.4M-record TransUnion breach, a Salesloft Drift AI token compromise, a Passwordstate high-severity fix, an Azure AD credential leak, and a WhatsApp zero-day. Watch the Talos Threat Perspective episode and read the Dell write-up for mitigation guidance.

🛡️ The U.S. Department of State is offering up to $10 million for information on three Russian FSB officers accused of carrying out cyberattacks against U.S. critical infrastructure. The named individuals — Marat Valeryevich Tyukov, Mikhail Mikhailovich Gavrilov, and Pavel Aleksandrovich Akulov — are tied to the FSB's Center 16, tracked under aliases such as Berserk Bear and Dragonfly. Charged in March 2022, the officers are alleged to have run intrusions from 2012–2017 targeting government agencies and energy firms, and recent activity shows exploitation of CVE-2018-0171 in end-of-life Cisco devices. The State Department directs tips to its Rewards for Justice Tor channel; eligible informants could receive rewards and relocation assistance.

🔒 Salt Typhoon, a persistent Chinese-aligned threat actor, has expanded operations into the Netherlands by compromising routers at smaller ISPs and hosting providers. Intelligence agencies report the group exploits known flaws in Ivanti, Palo Alto Networks, and Cisco devices to obtain long-term access and pivot through trusted provider links. Authorities urge organizations to audit configurations, disable management access, enforce public-key administrative authentication, remove default credentials, and keep vendor-recommended OS versions up to date to reduce exposure.

🔍 Salt Typhoon, a Chinese state-aligned APT also tracked as Operator Panda/RedMike, is the subject of a joint advisory from intelligence and cybersecurity agencies across 13 countries. The report links the group to Chinese entities tied to the PLA and MSS and documents repeated exploitation of n-day flaws in network edge devices from vendors such as Ivanti, Palo Alto Networks and Cisco. It details persistence via ACL modifications, tunneled proxies, credential capture via RADIUS/TACACS+, and exfiltration over peering and BGP, and urges telecoms to hunt for intrusions, patch quickly and harden management interfaces.

🔒Salt Typhoon, a China-linked APT, exploited vulnerabilities in Cisco, Ivanti, and Palo Alto Networks edge devices to compromise and persistently control routers worldwide. The actors modified device configurations, created GRE tunnels, and used on-box Linux containers to stage tools and exfiltrate data. Agencies from 13 countries linked the campaign to three Chinese firms and warned of espionage impacting telecoms, government, transport, lodging, and military sectors.

🔒 Cisco Talos disclosed multiple vulnerabilities affecting libbiosig, Tenda AC6, SAIL, PDF‑XChange Editor, and Foxit PDF Reader. The flaws include integer overflows, heap and stack buffer overflows, out‑of‑bounds reads, authentication and firmware validation weaknesses, and other memory corruption issues that can lead to remote code execution or information disclosure. Vendors have released patches in coordination with Talos and Snort coverage is available to detect exploitation attempts. Apply vendor updates and detection rules immediately to reduce exposure.

🛡️ FortiGuard Labs reports the resurgence of a Mirai-derived IoT malware family, publicly known as “Gayfemboy,” which reappeared in July 2025 targeting vulnerabilities in DrayTek, TP-Link, Raisecom, and Cisco devices. The campaign delivers UPX-packed payloads via predictable downloader scripts named for product families and uses a modified UPX header and architecture-specific filenames to evade detection. At runtime the malware enumerates processes, kills competitors, implements DDoS and backdoor modules, and resolves C2 domains through public DNS resolvers to bypass local filtering. FortiGuard provides AV detections, IPS signatures, and web-filtering blocks; organizations should patch and apply network defenses immediately.

🧭 The author opens with a travel anecdote and practical reminders on securing devices while on the road, urging readers to update, back up, and avoid public charging or untrusted Wi‑Fi. The newsletter highlights field-tested precautions including disabling auto-connect, using VPNs or phone hotspots, enabling device tracking, and carrying power banks. It also warns of an active campaign by a Russian state-backed group targeting Cisco devices via CVE-2018-0171, urging immediate patching and hardening.

🔒 Cisco Talos identifies the threat cluster Static Tundra as a long-running, Russian state-sponsored actor that compromises unpatched and end-of-life Cisco networking devices to support espionage operations. The group aggressively exploits CVE-2018-0171 and leverages weak SNMP community strings to enable local TFTP retrieval of startup and running configurations, often exposing credentials and monitoring data. Talos also observed persistent firmware implants, notably SYNful Knock, and recommends immediate patching or disabling Smart Install, strengthening authentication, and implementing configuration auditing and network monitoring to detect exfiltration and implanted code.

🔒 Cisco Talos identified a roughly 1.4× rise in ransomware incidents in Japan during H1 2025, with 68 confirmed cases versus 48 in the same period last year.
