🔒 Conduent has confirmed a breach affecting more than 10.5 million individuals, with customer notices sent in October 2025 after the incident was discovered on 13 January 2025. Unauthorized access reportedly began on 21 October 2024 and persisted for nearly three months. The criminal group SafePay claimed responsibility and said it exfiltrated large volumes of data, potentially including names, Social Security numbers, dates of birth, and medical and insurance information.

🔒 A China-affiliated group tracked as UNC6384 exploited an unpatched Windows shortcut flaw (ZDI-CAN-25373, CVE-2025-9491) to target diplomatic and government entities in Europe between September and October 2025. According to Arctic Wolf, the campaign used spear-phishing links to deliver malicious LNK files that launch a PowerShell stager, sideload a CanonStager DLL, and deploy the PlugX remote access trojan. Microsoft says Defender detections and Smart App Control can help block this activity.

🔒 Russian authorities have arrested three individuals in Moscow accused of creating and operating the Meduza information‑stealing malware. Announced on Telegram by police general Irina Volk, investigators say the group developed and distributed Meduza via hacker forums around two years ago and offered it as a subscription-based service. The tool steals browser-stored credentials and cryptocurrency data and, since December 2023, can resurrect expired Chrome authentication cookies to facilitate account takeover. Authorities opened a criminal case after operators targeted an Astrakhan institution and seized confidential server data.

⚠️ Sophos and JPCERT/CC have linked active exploitation of a critical Motex Lanscope Endpoint Manager vulnerability (CVE-2025-61932, CVSS 9.3) to the China-aligned Tick group. Attackers leveraged the flaw to execute SYSTEM-level commands and drop a Gokcpdoor backdoor, observed in both server and client variants that create covert C2 channels. The campaign used DLL side-loading to run an OAED Loader, deployed the Havoc post-exploitation framework on select hosts, and used tools like goddi and tunneled Remote Desktop for lateral movement. Organizations are advised to upgrade or isolate internet-facing LANSCOPE servers and review deployments of the MR and DA agents.

🔎 Researchers at Arctic Wolf Labs uncovered a September–October 2025 cyber-espionage campaign that used a Windows shortcut vulnerability to target Belgian and Hungarian diplomatic entities. The operation, attributed to UNC6384 and likely tied to Mustang Panda (TEMP.Hex), combined spear phishing with malicious .LNK files exploiting ZDI-CAN-25373 and deployed a multi-stage chain ending in the PlugX RAT. Attackers used DLL side-loading, signed Canon utilities and obfuscated PowerShell to extract and execute an encrypted payload while displaying decoy diplomatic PDFs.

🔒 A China-linked threat group is exploiting a high-severity Windows .LNK zero-day (CVE-2025-9491) to deploy the PlugX remote-access trojan against European diplomatic targets. The campaign begins with spearphishing that delivers malicious shortcut files themed around NATO and European Commission events. Researchers at Arctic Wolf Labs and StrikeReady attribute the activity to UNC6384 (Mustang Panda) and report the operation has expanded beyond Hungary and Belgium to other EU states. With no official patch available, defenders are urged to restrict .LNK usage and block identified C2 infrastructure.

🔒 A 43-year-old Ukrainian national, Oleksii Lytvynenko, has been extradited from Ireland to the United States on charges tied to the Conti ransomware operation. U.S. authorities allege he controlled stolen data and participated in sending ransom notes during double-extortion attacks between 2020 and June 2022. Arrested by An Garda Síochána in July 2023, Lytvynenko could face up to 25 years in prison if convicted. Prosecutors say the conspiracy extorted cryptocurrency and targeted victims across multiple jurisdictions.

🔒 The Eclipse Foundation said it revoked a small number of Open VSX access tokens after Wiz reported several VS Code extensions had inadvertently exposed credentials in public repositories. The exposures were attributed to developer error, not an Open VSX infrastructure compromise. Open VSX introduced an ovsxp_ token prefix, removed flagged extensions, reduced default token lifetimes, and plans automated scans to bolster supply‑chain defenses.

🔍 Researchers at Koi Security uncovered a campaign, PhantomRaven, that has contaminated 126 packages in Microsoft's npm repository by embedding invisible HTTP URL dependencies. These remote links are not fetched or analyzed by typical dependency scanners or npmjs.com, making packages appear to have 0 Dependencies while fetching malicious code at install time. The attackers aim to exfiltrate developer credentials and environment details, and they also exploit AI hallucinations to create plausible package names.

🔒 In a filing with the SEC, Ribbon Communications disclosed that unauthorized actors, reportedly tied to a nation-state, had access to its IT network, with initial intrusion activity traced as far back as December 2024. The company detected the breach in September 2025, has worked to terminate access, and is collaborating with third-party cybersecurity experts and federal law enforcement. Ribbon says it has not yet found evidence of material corporate data theft, although attackers accessed customer files on two laptops outside the main network.

🔒 Conduent has confirmed a 2024 data breach that state attorney general notifications indicate affected more than 10.5 million people. Reported exposed data includes names, Social Security numbers, full dates of birth, health insurance policy or ID numbers, and medical information. Conduent says the environment was first compromised on October 21, 2024 and discovered in January 2025; as of October 24, 2025 it reports no evidence the stolen data has been misused. Affected individuals are advised to obtain credit reports and consider fraud alerts or a security freeze; the company did not offer identity monitoring services.

🔒 Peter Williams, a former general manager at L3Harris Trenchant, pleaded guilty in U.S. court to stealing and selling protected cyber-exploit components between 2022 and 2025. Prosecutors say he removed at least eight sensitive trade-secret exploit components intended for exclusive government use and sold them to a broker that works with the Russian government for $1.3 million in cryptocurrency. He now faces up to 10 years in prison and significant fines.

🔒 AdaptixC2, an open-source command-and-control framework, has been adopted by multiple threat actors, including groups tied to Russian ransomware operations, prompting warnings about its dual-use nature. The tool offers encrypted communications, credential and screenshot managers, remote terminal capabilities, a Golang server, and a cross-platform C++ QT GUI client. Security firms Palo Alto Networks Unit 42 and Silent Push have analyzed its modular capabilities and traced marketing activity to a developer using the handle RalfHacker. Observed abuse includes fake Microsoft Teams help-desk scams and an AI-generated PowerShell loader used to deliver post-exploitation payloads.

🔓 A leaked Ministry of Defence spreadsheet in February 2022 exposed thousands of Afghan nationals who assisted UK forces, and research from the charity Refugee Legal Support shows the fallout continues. Survivors report murder, torture, repeated home searches and persistent Taliban threats; 49 people are reported to have lost relatives or colleagues. Only a minority were offered relocation to the UK, underscoring how data leaks and inadequate responses can cause real, ongoing harm.

⚠️ Silent Push reports a surge in malicious use of AdaptixC2, an open-source adversarial emulation framework that researchers say is now being delivered by the CountLoader malware as part of active ransomware operations. Deployments accelerated after new detection signatures were released, and public incident reports show increased sightings across multiple intrusions. Analysts flagged the developer alias RalfHacker and issued indicators covering Golang C2 traffic and unknown C++/QT executables.

🔒 Hackers are exploiting LinkedIn direct messages to phish finance executives with messages claiming to invite recipients to an executive board and leading to credential-harvesting pages. Push Security says victims are redirected — including via a Google open redirect — to a Firebase-hosted 'LinkedIn Cloud Share' page that urges users to click a 'View with Microsoft' button. That flow then presents a Cloudflare Turnstile and a fake Microsoft sign-in used as an adversary-in-the-middle to capture credentials and session cookies; organizations should verify senders, avoid unsolicited links, and enforce MFA and conditional access.

🛡️ Hezi Rash is a Kurdish nationalist hacktivist collective formed in 2023 that has escalated to coordinated DDoS campaigns targeting entities perceived as hostile to Kurdish or Muslim communities. Their public rhetoric mixes nationalism, religion, and activism, and they have claimed attacks in response to symbolic provocations such as an anime scene depicting a burning Kurdish flag. Targets reported include anime platforms, media outlets, NGOs, and government services, causing intermittent service disruptions and demonstrating growing technical sophistication.

🚨 A multi-stage supply-chain campaign published ten typosquatted npm packages on July 4 that collectively reached nearly 10,000 downloads before removal, according to Socket. Each package abused npm’s postinstall lifecycle to open a new terminal, present a fake CAPTCHA prompt, and retrieve a PyInstaller-packed binary that harvests credentials from browsers, OS keyrings, SSH keys, tokens and cloud configuration files. The JavaScript installers combined four layers of obfuscation with social engineering to evade detection and delay scrutiny while exfiltrating collected secrets to the attacker’s host.

🔎 Proton and Constella Intelligence have launched the Data Breach Observatory, a real‑time dark‑web monitoring service that has identified more than 300 million compromised records tied to 794 incidents so far this year. The service combines automated crawlers, curated feeds and human analysts to surface breached data and alert affected parties. Proton says small and medium businesses are heavily targeted, with email addresses, names and contact details the most commonly exposed items. If aggregated datasets are included, Proton reports incidents rise to 1,571 and exposures reach hundreds of billions of records.

⚠️ Koi Security has identified a supply-chain campaign dubbed PhantomRaven that inserted malicious code into 126 npm packages, collectively installed more than 86,000 times, by pointing dependencies to an attacker-controlled host (packages.storeartifact[.]com). The packages include preinstall lifecycle hooks that fetch and execute remote dynamic dependencies, enabling immediate execution on developers' machines. The payloads are designed to harvest GitHub tokens, CI/CD secrets, developer emails and system fingerprints, and exfiltrate the results, while typical scanners and dependency analyzers miss the remote dependencies because npmjs.com does not follow those external URLs.
