Attackers exploited a flaw in an optional Nextcloud app, Collabora Online - Built-in CODE Server, to plant web shells on Nextcloud servers. Three administrators reported the issue on GitHub, with the first logged attack on September 10. A web shell is a small file that executes any command an attacker sends via a web request, with the rights of the web server account. The flaw
Microsoft and Health-ISAC, along with the Japan Cybercrime Control Center (JC3) and a coalition of private sector companies, such as Resecurity, Cloudflare, Oracle, Proofpoint, and TRM Labs, announced the disruption of three phishing kits, CoGUI (aka NX or FA), Haozi (aka Phoenix), and Iron Man System. "Since January 2026, the threat actors behind these kits have been responsible for
A new Android malware called Hirudo steals bank account credentials by replacing legitimate banking apps with modified versions that disable security checks.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday urged organizations to take steps to immediately update their Ivanti Connect Secure (ICS) appliances and deployments to the latest version following the disclosure of an actively exploited vulnerability. The security flaw, tracked as CVE-2026-104935 (CVSS score: 8.6), is a case of authentication bypass impacting ICS
Cybersecurity researchers have disclosed details of a new Android banking trojan called Hirudo that works by replacing legitimate banking apps with purpose-built patched versions designed to bypass security checks from inside the app itself, marking a new escalation in financial fraud. Dutch mobile security company ThreatFabric said it identified replacements for eight Indonesian banking
The bug was simple: the login let you choose where your sign-in code went. Proving it on a live website was the hard part. TL;DR During an authorized assessment, an AI pentesting agent found a critical authentication bypass on a major insurer's production website, on its own. One login request let the user choose where the one-time passcode went. The attack was the easy part. Proving it
A critical heap buffer overflow vulnerability (CVE-2026-39919) in the Ghostscript interpreter and rendering engine could allow remote code execution through specially crafted PDF files. The flaw was discovered on August 23 by researchers at Defiant's platform Wordfence using their Argus AI-powered system. Ghostscript is a PostScript and PDF interpreter that can render PDFs as images, generate thumbnails for previews, and optimize PDF files by compressing embedded images and removing unnecessary font data. When generating a PDF thumbnail, WordPress can use the PHP Imagick extension to call ImageMagick, which launches Ghostscript. A specially crafted PDF file containing a JPEG 2000 image can trigger incorrect handling of low-bit-depth samples and mismatched component resolutions. Using Argus, the researchers developed two exploits for CVE-2026-39919 that force Ghostscript to write 1,024 bytes into a 256-byte buffer, corrupting nearby memory and leading to unauthenticated remote code execution in a WordPress deployment.
Small artificial intelligence (AI) models may be months away from developing capabilities to self-replicate on IoT devices like smart ovens and off-brand Android TV boxes, according to a warning from Anthropic. The frontier AI lab said small AI models could form autonomous, self-propagating worm botnets that are "challenging to shut down," since "there's no centralized point to shut off."
The U.K. Housing Ombudsman Service is investigating a third-party IT security incident that impacted its case management system on Tuesday. Established under the Housing Act 1996, the Housing Ombudsman is an executive non-departmental public body sponsored by the Ministry of Housing, Communities, and Local Government. The watchdog settles disputes between social housing residents and social landlords in England, including housing associations, landlords, managers, and letting agents. On Tuesday, the service added an alert to its official website, warning that it's working with the affected service provider to assess the incident's impact and said social housing residents cannot file new complaints until systems are back online. Those who must raise new complaints are advised to call the Housing Ombudsman's phone line or email the watchdog at info@housing-ombudsman.org.uk.
Attackers continue exploiting gaps in MFA coverage, using stolen credentials to access VPNs, RDP, and Windows systems that still rely on passwords alone. Specops explains why protecting cloud applications isn't enough and how organizations can close these authentication gaps.
