DDoS Mitigation Provider Hit by 1.5 Billion PPS Attack

🚨 A European DDoS mitigation provider was hit by a massive packet-rate flood that peaked at 1.5 billion packets per second. FastNetMon detected the assault, which originated from thousands of compromised customer premises devices, including IoT units and MikroTik routers across more than 11,000 networks. The malicious traffic was primarily a UDP flood and was mitigated in real time using the customer's scrubbing facility, ACLs on edge routers, and packet inspection. FastNetMon warned this trend requires ISP-level filtering to prevent large-scale abuse of consumer hardware.

US Charges Alleged Ransomware Kingpin; $10M Reward

🚨 A US federal court has unsealed charges against Ukrainian national Volodymyr Viktorovich Tymoshchuk, accused of orchestrating ransomware campaigns using LockerGoga, MegaCortex, and Nefilim. Authorities say these campaigns, active between December 2018 and October 2021, targeted over 250 US companies and hundreds more worldwide. Tymoshchuk — also known by aliases such as 'deadforz', 'Boba', and 'msfv' — remains at large. The US is offering a $10 million reward for information leading to his arrest and conviction.

Largest npm Supply Chain Attack Injects Crypto Malware

🛡️ On September 8, 2025, a sophisticated phishing campaign led to the compromise of a trusted maintainer account and the insertion of cryptocurrency-stealing malware into more than 18 foundational npm packages. The malicious versions collectively represented over 2 billion weekly downloads and affected millions of applications from personal projects to enterprise systems. The debug package was among those compromised and alone exceeds 357 million weekly downloads. npm has removed several malicious package versions and is coordinating ongoing remediation.

Massive NPM Supply-Chain Attack Yielded Little Profit

🚨 A phishing attack against maintainer Josh Junon (qix) led to a widespread compromise of highly popular npm packages, including chalk and debug-js, whose combined footprint exceeds billions of weekly downloads. The attacker pushed malicious updates that attempted to steal cryptocurrency by swapping wallet addresses, but the community discovered and removed the tainted releases within two hours. According to Wiz, the compromised modules reached roughly 10% of cloud environments in that short window, yet the actor ultimately profited only minimally as the injected payload targeted browser crypto-signing and yielded just a few hundred dollars at most.

Chinese APT Uses EggStreme Fileless Framework in Espionage

🛡️ Bitdefender attributed a campaign against a Philippines-based military contractor to a China-linked APT that deployed a previously undocumented fileless framework named EggStreme. The multi-stage operation begins with EggStremeFuel (mscorsvc.dll), which profiles systems, opens a C2 channel, stages loaders, and triggers in-memory execution of the core backdoor via DLL sideloading. EggStremeAgent functions as a central backdoor, injecting a session-specific keylogger (EggStremeKeylogger), communicating over gRPC, and exposing a 58-command toolkit for discovery, lateral movement, privilege escalation and data theft. An auxiliary implant, EggStremeWizard (xwizards.dll), provides reverse-shell access and resilient C2 options; Bitdefender warned that fileless execution and heavy DLL sideloading make detection and forensics difficult.

Salty2FA Phishing Framework Evades MFA Using Turnstile

🔒 A newly identified phishing-as-a-service called Salty2FA is being used in campaigns that bypass multi-factor authentication by intercepting verification flows and abusing trusted services like Cloudflare Turnstile. Ontinue researchers report the kit uses subdomain rotation, domain-pairing, geo-blocking and dynamic corporate branding to make credential pages appear legitimate. The framework simulates SMS, authenticator apps, push approvals and even hardware-token prompts, routing victims through Turnstile gates to filter automated analysis before harvesting credentials.

Jaguar Land Rover Confirms Data Theft After Cyberattack

🔒 Jaguar Land Rover (JLR) confirmed that attackers stole "some data" during a recent cyberattack that forced system shutdowns and instructed staff not to report to work. The company disclosed the disruption on September 2 and says it is working with the U.K. National Cyber Security Centre and third‑party specialists to restart applications in a controlled manner. JLR has notified relevant regulators and said its forensic investigation is ongoing; it will contact individuals if their data is affected. No definitive attribution or confirmed ransomware claim has been announced.

KillSec Ransomware Disrupts Brazilian Healthcare IT

🔒 A ransomware incident attributed to KillSec has disrupted MedicSolution, a Brazilian healthcare IT vendor, after attackers claimed to exfiltrate more than 34 GB comprising 94,818 files. Resecurity reports the haul includes medical evaluations, lab results, X‑rays and unredacted patient photos, and says data was exposed via misconfigured AWS cloud buckets. MedicSolution has not publicly responded; regulators and affected providers face notification and remediation challenges.

Social-Engineered Help Desk Breach Costs Clorox $380M

🔐 Attackers affiliated with the Scattered Spider group exploited weak vendor phone procedures to obtain repeated password and MFA resets from Cognizant’s service desk, then used the access to escalate to domain-admin footholds at Clorox. Clorox says the intrusion caused roughly $380 million in damages, including remediation and extended business-interruption losses. The case highlights failure to follow agreed verification processes and the amplified risk of outsourced help desks. Organizations should enforce out-of-band caller verification, immutable reset logs, and automated containment to reduce the attacker window.

The Gentlemen ransomware targets OT-heavy industries

🔒 A newly observed ransomware group, The Gentlemen, has rapidly expanded operations across Asia Pacific, South America, the US and the Middle East since first being identified in August. Trend Micro reports the group leverages legitimate drivers, GPO abuse and custom tooling to disable endpoint security and move laterally. Victims span manufacturing, construction, healthcare and insurance, and defenders are urged to adopt zero-trust, behavioral EDR/XDR and rigorous segmentation.

SalesLoft Drift Breaches Expose Fourth-Party OAuth Risk

🔐 The SalesLoft acquisition of Drift exposed a hidden fourth‑party attack surface when legacy OAuth tokens—some dormant for 18 months—were abused to access customer Salesforce instances and a limited number of Google Workspace accounts. Attackers leveraged inherited tokens to enumerate and exfiltrate data, revealing how M&A can transfer persistent permissions outside visibility. The author calls for continuous, behavior‑based monitoring of every OAuth token and API call and recommends practical "OAuth archaeology" to inventory, rotate, or revoke legacy access.

AdaptixC2: Open-Source Post-Exploitation Framework Used

🛡️ Unit 42 observed AdaptixC2 in early May 2025 being used in real-world intrusions to perform command execution, file transfers and data exfiltration. The open-source framework offers modular beacons, in-memory execution and multiple persistence and tunneling options, which adversaries have adapted for evasive operations. Unit 42 published extraction tools, YARA rules and hunting guidance to help defenders detect and mitigate these threats.

China-linked APT41 Targets U.S. Trade Policy Networks

🔒 The House Select Committee on China warned of an ongoing series of targeted cyber-espionage campaigns tied to the PRC that aim at organizations involved in U.S.–China trade talks. Attackers impersonated Rep. John Robert Moolenaar in phishing emails that delivered malware via attachments and links, abusing cloud services and software to conceal activity. The campaign, attributed to APT41, affected trade groups, law firms, think tanks, U.S. government agencies and at least one foreign government.

Lovesac Discloses Customer Data Breach Linked to RansomHub

🔒 Lovesac has informed customers that an unauthorized actor accessed its systems between February 12 and March 3, 2025, copying certain files after the company detected suspicious activity at the end of February. The intrusion aligns with a March claim by RansomHub, which said it had stolen roughly 40 GB of data; the ransomware group's extortion portal later went offline in April. Lovesac says it has found no confirmed misuse of the stolen information, but is notifying affected customers, offering 24 months of complimentary credit monitoring through Experian (enrollment required and open until November 28, 2025), and urging vigilance for signs of identity theft and fraud.

Malicious npm Code Reached 10% of Cloud Environments

⚠️ Security researchers warn a supply‑chain attack on npm briefly propagated trojanized versions of widely used packages after the developer account qix was hijacked via social engineering. The malicious updates contained crypto‑stealing payloads that could rewrite wallet recipients in browsers if bundled into frontend builds. Vendor Wiz reports the code was present in about 10% of cloud environments during a two‑hour window, and JFrog says additional accounts, including DuckDB, were impacted. Organizations are advised to blocklist affected versions, rebuild from clean caches, invalidate CDN assets, and hunt for affected bundles and anomalous signing activity.

Salty2FA Phishing Kit Targets US and EU Enterprises

⚠️ Researchers at ANY.RUN have uncovered Salty2FA, a new phishing-as-a-service kit engineered to harvest credentials and bypass multiple two-factor authentication methods. First observed gaining momentum in mid-2025, the kit uses multi-stage redirects, Cloudflare checks and evasive hosting to slip past automated filters. Salty2FA intercepts push, SMS and voice codes, enabling account takeover across finance, energy and telecom sectors.

Data Is the New Diamond: Evolving Salesforce Data Theft

🔒 Recent Unit 42 analysis details ongoing data theft campaigns targeting Salesforce environments, notably a Salesloft Drift supply chain intrusion attributed to UNC6395 that may have started with reconnaissance as early as March 2025. Threat actors claiming links to Muddled Libra and Bling Libra have promoted stolen datasets on Telegram and announced new RaaS ambitions, while some channels were removed by September 5. Unit 42 emphasizes the prominence of social engineering by operatives tied to "The Com," predicts shifts toward data theft extortion and other monetization tactics, and recommends engagement with RH-ISAC, adoption of Salesforce mitigations, and use of Unit 42 incident insights to strengthen people and process defenses.

Actors Hide Behind Tor in Exposed Docker API Campaign

🛡️ Attackers are exploiting exposed Docker APIs (port 2375) by launching containers that install Tor and retrieve secondary payloads from hidden services. Researchers at Trend Micro and Akamai observed the activity evolve from opportunistic cryptomining into a more capable dropper that establishes persistent SSH access, creates cron jobs to block API access, and executes a Go-based agent that scans and propagates to additional hosts. The agent also removes competitor containers and contains dormant logic for Telnet and Chrome remote debugging exploitation.

Kosovo Hacker Pleads Guilty to Running BlackDB Market

🔒 Kosovo national Liridon Masurica has pleaded guilty to operating the cybercrime marketplace BlackDB.cc, which the Justice Department says sold compromised accounts, server credentials, stolen credit cards, and PII since 2018. Masurica was arrested in Kosovo in December 2024, extradited to the United States in May 2025, and is detained following a court appearance in Tampa. He faces federal charges that include five counts of fraudulent use of unauthorized access devices and a conspiracy count, carrying up to 55 years in prison. The FBI coordinated the investigation with Kosovo law enforcement and international partners.
