Microsoft on Tuesday announced the takedown of the EvilTokens device code phishing service that it said used artificial intelligence (AI) "at every step of the attack chain." The action, carried out with authorization from the U.S. District Court for the Eastern District of Virginia, involved the efforts of Health-ISAC, alongside Cloudflare, Coinbase, Ope...
A critical vulnerability in Bifrost, an open-source AI gateway that routes requests to more than 20 LLM providers, allows an unauthenticated attacker to run arbitrary commands on the gateway server with a single HTTP request. The flaw, tracked as CVE-2026-90898 (CVSS score: 9.8), affects all versions of the Bifrost HTTP transport before 2.1.0 when managem...
A zero-day proof-of-concept tool that stops Microsoft Defender from installing platform and signature updates by filling all available disk space was published on GitHub on September 19. The tool, called BigDiskBuster, has no patch, no CVE, and no Microsoft advisory. Its author, Abdelhamid Naceri, is a former Microsoft security researcher whose earlier De...
Security teams have spent decades asking whether an identity has too much access. AI agents raise a harder question: how can we determine which paths an autonomous system can discover, given the access it already has? A person may try several ways to complete a task. A deterministic application follows the flow its developer wrote. But an AI agent is rele...
Attackers are exploiting a new flaw in on-premises VeloCloud Orchestrator (VCO), the server that manages the Edge devices in a VeloCloud SD-WAN, Arista said on September 22. The flaw, tracked as CVE-2026-93952, may allow a remote attacker with no login access to privilege internal functions and affect the VCO host. Only orchestrators set up to authenticat...
When the Digital Operational Resilience Act (DORA) became enforceable across the European Union in January 2025, it triggered an administrative sprint. Financial entities spent the first year establishing risk governance, assessing third-party service providers, updating contract clauses, and documenting incident escalation workflows. Now in its second ye...
A new flaw in the Linux kernel's KVM virtualization code for ARM64 processors can leave a freed piece of host memory exposed to a guest virtual machine on hosts with nested virtualization enabled. The bug, tracked as CVE-2026-89775, allows a guest to read and write host kernel memory, and the researcher who found it says it can be used to escape the guest...
A SharePoint Server vulnerability that Microsoft initially classified as a spoofing flaw with a CVSS score of 6.5 actually enables authenticated remote code execution, according to full technical details published today by Viettel Cyber Security researcher Dinh Ho Anh Khoa. The flaw, CVE-2026-65660, affects SharePoint Server 2016, 2019, and Subscription E...
A malicious npm package named "indexed-btree" has been observed hiding its malicious behavior within application code rather than using lifecycle scripts, indicating that threat actors are likely shifting tactics in response to recent security controls. "Indexed-btree is a malicious npm package mimicking the legit sorted-btree package, an ordinary B-tree/...
The threat actor known as SideCopy has been observed using spear-phishing lures to target academic institutions in India, expanding their strategic focus beyond government entities. "SideCopy campaign operations typically initiate through spear-phishing campaigns that leverage the abuse of mshta.exe to execute malicious scripts and circumvent standard sec...
Malware already running on a Mac can quietly take over Meta's Muse assistant and use the broad access its owner granted the app, security researcher Patrick Wardle has shown in a proof-of-concept released on September 21. It works by changing a hidden setting so that when the user taps the microphone and dictates a prompt, the words go to the attacker ins...
A new flaw in WordPress core let an anonymous visitor leave a comment that planted a hidden script on the page. If a logged-in administrator later opened that page, the script could run code on the site's server. WordPress fixed the flaw, tracked as CVE-2026-93485 and called "Comment2Shell," on September 17 in version 7.1.1 and told site owners to update ...
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a now-patched security flaw impacting Zyxel GS1900 series switches to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. The vulnerability, tracked as CVE-2026-7273 (CVSS score: 8.8), is a stack-based buffer overflow vulnerability that ...
A fake LastPass Authenticator installer offered on GitHub installs a Windows kernel driver that shuts off antivirus and other security software before a password stealer runs if a victim downloads and runs it, researchers at LastPass and Delphos Labs said on September 17. Microsoft's own hardware-compatibility program signs the driver, scored zero detecti...
The North Korean threat actors behind the Contagious Interview campaign have compromised at least 30,000 devices located in more than 100 countries and siphoned funds or account credentials from over 7,000 cryptocurrency wallets, according to a new joint cybersecurity advisory. The primary targets of the campaign are individual web designers, engineers, a...
Google has been fined €403 million for breaking the EU's data protection law, the GDPR, in the way three of its features handled people's location data from May 2018 to February 2020. Ireland's Data Protection Commission (DPC), Google's lead regulator in the EU, also ordered the company to make its processing comply with the law within 6 months. The DPC h...
A browser. A plugin. A package. A login screen. Normal stuff. That is basically the problem this week. The trouble keeps showing up inside things people already trust: code that takes a bad turn, old payloads coming back, exposed systems, weak checks, fake fixes, and attack paths that look almost too easy. Even the research side is getting messy, with mor...
Cybersecurity researchers have disclosed details of a new campaign dubbed TASK#STOMP that delivers a PowerShell backdoor designed to harvest sensitive data from compromised hosts. The backdoor "automatically harvests and exfiltrates business documents, watches the filesystem for new files in real time, steals Wi-Fi passwords and clipboard contents, takes ...
