All news with #credential stuffing tag

🔒 Security researchers observed a coordinated credential-stuffing campaign targeting Cisco SSL VPN and Palo Alto Networks GlobalProtect portals over a two-day span in mid-December. GreyNoise reported millions of automated login sessions from more than 10,000 unique IPs, using a consistent TCP fingerprint and a Firefox-like user agent. The activity did not exploit software flaws but instead relied on large-scale username/password probes. Analysts urged enforcing strong passwords and MFA, auditing exposed edge devices, and leveraging threat-intel blocklists to filter malicious traffic.

🔒 Nathan Austad, 21, pleaded guilty to conspiring to commit computer intrusion after participating in a credential stuffing campaign that compromised more than 60,000 user accounts on a fantasy sports betting site in November 2022. Prosecutors say attackers added payment methods, drained balances and sold account access on online marketplaces; roughly $600,000 was stolen from about 1,600 victims. Investigators say Austad ran an online shop and controlled cryptocurrency wallets that received approximately $465,000 in proceeds. He acknowledged awareness of an active investigation and faces up to five years in prison, with sentencing scheduled for April 10, 2026.

🔒 Retailers face concentrated credential risk during holiday peaks as bot-driven fraud, credential stuffing and pre-staged automated attacks target logins, payment tokens and loyalty balances. Effective defenses combine adaptive MFA, bot management, rate limiting and credential-stuffing detection to stop automation without harming checkout conversion. Strong controls for staff and third parties, plus tested failovers and tools like Specops Password Policy to block compromised passwords, reduce blast radius and protect revenue.

🔒Identity-focused attacks are driving major breaches across industries, with recent vishing incidents at M&S and Co-op enabling ransomware intrusions and combined losses exceeding £500 million. Attackers harvest credentials via infostealers, targeted phishing/smishing/vishing, breached password stores and automated attacks like credential stuffing. Implement least privilege, strong unique passwords in managers, MFA (authenticator apps or passkeys), PAM and automated identity lifecycle controls to limit blast radius.

🛡️ FortiGuard Labs' 2025 holiday analysis documents a marked increase in malicious infrastructure, credential theft, and targeted exploitation of e-commerce systems during the pre-holiday period. Attackers registered tens of thousands of holiday- and retail-themed domains and sold over 1.57 million account records from stealer logs, fueling credential stuffing and account takeover. The report highlights active exploitation of critical flaws in platforms such as Magento, Oracle EBS, and WooCommerce, and emphasizes urgent mitigations: patching, MFA, bot management, domain monitoring, and payment-page integrity checks to reduce fraud and protect customers.

🔒 Social media influencers are increasingly attractive targets for cybercriminals who hijack trusted accounts to distribute scams, malware and fraudulent offers. Attackers use spearphishing, credential stuffing, brute-force attacks and SIM swapping, and AI is making those lures more convincing. Compromised accounts may be sold or used to push crypto and investment scams, exfiltrate follower data or extort victims. Practical defences include long, unique passwords, app-based 2FA, phishing awareness, device separation and up-to-date security software.

🛡️ ThreatFabric has detailed a new Android banking trojan named Sturnus that combines screen-capture, accessibility abuse, and overlays to steal credentials and enable full device takeover. The malware captures decrypted messages from WhatsApp, Telegram, and Signal by recording the device screen, serves region-specific fake banking login screens, and contacts operator servers via WebSocket/HTTP to receive encrypted payloads and enable remote VNC-style control. It resists cleanup by blocking uninstallation and leveraging administrator privileges.

🔒Sturnus is a new Android banking trojan discovered by ThreatFabric that can capture decrypted messages from end-to-end encrypted apps like Signal, WhatsApp, and Telegram. It abuses Accessibility services and on-screen capture to read message content and deploys HTML overlays to harvest banking credentials. The malware also supports real-time, AES-encrypted VNC remote control and obtains Android Device Administrator privileges to resist removal while targeting European financial customers with region-specific overlays.

🔒 Kunal Mehta, a 45-year-old from Irvine, has pleaded guilty to laundering at least $25 million connected to a wider $230 million cryptocurrency theft. Court documents say Mehta served as a money launderer for a transnational ring that used social engineering between October 2023 and March 2025 to access victims' crypto accounts. Prosecutors allege he created multiple shell companies in 2024, routed wire transfers into bank accounts designed to appear legitimate, and typically charged a 10% fee for converting stolen crypto to cash. Investigators say the group employed mixers, peel chains, pass-through wallets, VPNs, and conversions to Monero, though operational mistakes helped link laundered funds back to the theft.

🔒 Security researchers from Socura and Flare found around 460,000 compromised credentials tied to FTSE 100 domains across clear- and dark-web crime communities, including 28,000 entries from infostealer logs. The report notes many companies had thousands of leaks and that password hygiene remains poor, with 59% having at least one user using 'password'. It recommends MFA, passkeys, password managers, conditional access and proactive leak monitoring.

🚨 The UK's National Crime Agency (NCA) has launched the "Crypto Dream Scam Nightmare" campaign to warn men under 45 about crypto investment fraud that lures victims with professional sites, apps and romance baiting. The initiative, part of the Home Office's Stop! Think Fraud programme, includes a short video and a 10-tip info sheet to help people recognise and avoid scams. The NCA noted Action Fraud logged over 17,000 investment fraud reports last year.

🔒 Sekoia warns of a large-scale phishing campaign targeting hotel staff that uses ClickFix-style pages to harvest credentials and deliver PureRAT. Attackers impersonate Booking.com in spear-phishing emails, redirect victims through a scripted chain to a fake reCAPTCHA page, and coerce them into running a PowerShell command that downloads a ZIP containing a DLL-side‑loaded backdoor. The modular RAT supports remote access, keylogging, webcam capture and data exfiltration and persists via a Run registry key.

🔐 Computer-using agents (CUAs) — AI systems that perceive screens and act like humans — are poised to scale phishing and credential-stuffing attacks by automating UI interactions, adapting to layout changes, and bypassing anti-bot defenses. Organizations should move beyond passwords and shared-secret MFA to device-bound, cryptographic authentication such as FIDO2 passkeys and PKI-based certificates to reduce large-scale compromise. SaaS vendors must integrate with identity platforms that support phishing-resistant credentials to strengthen overall security.

🔐 The article outlines how everyday credential reuse and phishing feed a persistent compromise lifecycle: credentials are created, stolen, aggregated, tested, and ultimately exploited. It details common vectors — phishing, credential stuffing, third-party breaches, and leaked API keys — and describes criminal marketplaces, botnets, opportunistic fraudsters, and organized crime as distinct actors. Consequences include account takeover, lateral movement, data theft, resource abuse, and ransomware, and the piece urges immediate action such as scanning for leaked credentials with tools like Outpost24's Credential Checker.

🛡️ Proofpoint has identified a previously unknown cluster it calls UNK_SmudgedSerpent that targeted academics and foreign policy experts between June and August 2025. Attackers initiated benign, topical conversations and used think‑tank impersonation alongside an OnlyOffice‑styled link that led to health-themed domains harvesting credentials and delivering a ZIP with an MSI. The installer deployed remote monitoring and management tooling — notably PDQConnect and later ISL Online — and although email activity paused in early August, related infrastructure later surfaced hosting TA455-linked malware, leaving attribution unresolved.

🔒 FortiGuard Incident Response observed that in H1 2025 financially motivated actors frequently used stolen credentials and legitimate remote-access software to gain and extend access across environments. Adversaries relied on compromised VPN logins, password reuse, or purchased credentials, deploying tools like AnyDesk, Splashtop, Atera and ScreenConnect to move laterally and exfiltrate data manually. These intrusions often bypass endpoint-focused defenses because activity mimics normal user behavior, so FortiGuard emphasizes identity- and behavior-driven detection, broad MFA enforcement, and monitoring of remote access tooling.

🔍 Security researchers at Varonis identified a modular remote access trojan named Atroposia, first seen on October 15 and promoted on underground forums. The toolkit includes encrypted C2 channels, hidden remote desktop takeover (HRDP Connect), credential and cryptocurrency wallet theft, DNS hijacking, vulnerability scanning and robust persistence. It is offered via subscription tiers and can be combined with services like SpamGPT and MatrixPDF to automate phishing and delivery. Recommended defenses include phishing reduction, timely patching, MFA enforcement and monitoring for post-compromise activity.

⚠️ Check Point researchers uncovered a long-running operation that uploaded and promoted over 3,000 YouTube videos linking to malware downloads. The network, dubbed the YouTube Ghost Network, has been active since 2021 and saw its volume triple this year, using hacked channels and a role-based structure to sustain distribution. Videos offering pirated software and Roblox cheats pointed users to cloud-hosted files or phishing pages that deployed stealers and Node.js loaders, and Google has removed the majority of identified content.

🔎 GTIG describes a targeted campaign by a Vietnam-based cluster tracked as UNC6229 that uses fake job postings on legitimate platforms to socially engineer remote digital advertising workers. Victims are enticed to open password-protected attachments or visit convincing phishing portals that harvest corporate credentials and can bypass MFA. The actors abuse reputable CRM and SaaS services to increase trust, deliver remote access trojans, and ultimately take over high-value advertising and social media accounts for sale or resale.

🔒Researchers detail a threat cluster called Jingle Thief that leverages phishing and smishing to harvest credentials and compromise cloud environments of retailers and consumer services to issue unauthorized gift cards. Palo Alto Networks Unit 42 links the activity to financially motivated actors and notes coordinated campaigns in April-May 2025. The attackers favor identity misuse over malware, persistently mapping tenants, abusing Microsoft 365 services, and minimizing logs to sustain large-scale fraud.
