Chrome Ad Blocker with 10M+ Installs Found with Dormant Script Injection Capability

An analysis of a popular Google Chrome ad block extension for YouTube has uncovered the ability to execute arbitrary JavaScript code. According to Island, the extension, named Adblock for YouTube (ID: cmedhionkhpnakcndndgjdbohmhepckk), has more than 10 million installs and carries a Featured badge on the Chrome Web Store. The extension description states that it allows users to prevent web page elements like ads, including preroll ads, from being displayed on the video sharing platform, as well as on external sites that load YouTube. While the add-on offers the promised functionality, it also features capabilities to run arbitrary JavaScript code. "It also contains the architectural ingredients for arbitrary JavaScript execution on any website, activated by a single server-side configuration change, without an extension update, without a store review, and without any visible sign that something has changed," researchers Oleg Zaytsev and Shachar Gritzman said in a re...

ThreatsDay Bulletin: Smart TV Proxyware, 24-Year curl Bug, AI Crime Forums + 13 More Stories

It’s dumb out there again. This week has the usual smell of prod on fire and nobody wanting to admit who left the door open — old creds still working, trusted apps doing sketchy crap, browser tricks jumping the fence, and “normal” workflows turning into phishing pipes because apparently email was not enough hell already. The worst part is how cheap some of it feels. Not elite. Not cinematic. Just stale secrets, fake updates, lazy trust, and random boxes quietly becoming someone else’s infrastructure. Same internet, fresh headache. Let’s get into it.

Surviving the Mythos Era: Richard Bejtlich on the Case for NDR

Despite the abundance of telemetry at analysts’ disposal, many security operations teams struggle to answer a few basic questions during incident investigation: What happened? What evidence do we have? How do we know we’re seeing it all, in context? Answering these questions requires teams to go beyond alerts, the most common basis for initial triage. But investigations (and their outcomes) require defensible evidence, not assumptions, which is what alerts tend to offer.  Alerts are becoming less useful as vulnerability discovery accelerates (a.k.a., the Mythos Era). Most organizations can’t investigate the volume of new findings with existing workflows. Even with increased automation, SecOps teams need validated evidence of active exploit and exposure, not more raw telemetry. As AI expedites both attacks and defense, security teams need to lay the groundwork that allows them to validate findings, understand attacker behavior, and stop suspicious traffic before it results in...

New Gaslight macOS Malware Uses Prompt Injection to Disrupt AI-Assisted Analysis

A previously undocumented Rust-based macOS implant and information stealer has been found to embed a prompt injection payload designed to trick a malware analyst's artificial intelligence (AI) tools and trick it into aborting or refusing an analysis of the artifact. The malware has been codenamed Gaslight owing to this deceptive behavior. It's been assessed with high confidence that the tool is the work of North Korea-aligned threat actors. "Its most notable feature is an embedded cascade of fabricated system-failure messages, designed to make an LLM-assisted triage agent doubt its own session," SentinelOne researcher Phil Stokes said in a technical report. "It attacks the agent's perception, rather than the sandbox it runs in." Central to the malware's architecture is a Telegram bot API based command-and-control (C2) channel that enters into a polling loop, allowing the operator to issue instructions over an interactive shell and return the...

New Mistic Backdoor Linked to KongTuke in ClickFix and ModeloRAT Campaigns

A new, stealthy backdoor named Mistic has been deployed as part of suspected financially motivated attacks aimed at multiple organizations spanning insurance, education, IT, and professional services sectors since April 2026. According to Symantec and Carbon Black's Threat Hunter Team, the backdoor, also tracked as MLTBackdoor, is said to be linked to an initial access broker (IAB) named KongTuke (aka 404 TDS, Chaya_002, LandUpdate808, TAG-124, and Woodgnat), and dropped along with ModeloRAT, a Python remote access trojan (RAT) previously attributed to the group. "The backdoor runs payloads in memory with no file written to disk and includes a kill switch that lets it delete itself, which are features consistent with an operator seeking long-term, low-visibility access," Broadcom's cybersecurity teams said in a report shared with The Hacker News. ModeloRAT was first flagged by Huntress in January 2026 in connection with a variant of a ClickFix campaign dub...

Cisco Catalyst SD-WAN Zero-Day CVE-2026-20245 Exploited to Gain Root Access

An unknown threat actor exploited a recently disclosed high-severity security flaw impacting Cisco Catalyst SD-WAN as a zero-day at least two months before it was publicly disclosed, according to new findings from Google-owned Mandiant. The vulnerability, tracked as CVE-2026-20245 (CVSS score: 7.8), allows an authenticated, local attacker to execute arbitrary commands with elevated privileges by supplying a crafted file to the affected system by taking advantage of the device's insufficient validation of user-supplied input. Earlier this month, Cisco acknowledged that it became aware of exploitation of this vulnerability, adding that a malicious actor must have netadmin privileges on an affected system to pull off a successful attack. "Throughout the intrusion, to maintain operational security and avoid detection, the threat actor consistently employed anti-forensic techniques, selectively deleting and restoring system configuration files that were modified during the...

CISA Warns Critical Lantronix EDS5000 Flaw Is Being Actively Exploited

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday warned of active exploitation of a critical security flaw impacting Lantronix EDS5000 Series devices, urging Federal Civilian Executive Branch (FCEB) agencies to apply the fixes by June 26, 2026. The vulnerability in question is CVE-2025-67038 (CVSS score: 9.8), a code injection flaw that could result in the execution of arbitrary commands with elevated privileges. "The HTTP RPC module executes a shell command to write logs when the user's authentication fails," according to the vulnerability's description on CVE.org. "The username is directly concatenated with the command without any sanitization. This allows attackers to inject arbitrary OS commands into the username parameter. Injected commands are executed with root privileges." The security flaw was disclosed by Forescout Research Vedere Labs in April 2026 as part of a broader set of vulnerabilities collectively cod...

Amadey and StealC Malware Network Disrupted, 27M Stolen Credentials Recovered

A coordinated law enforcement operation, in partnership with private sector companies, including Bitdefender, Bitsight, ESET, and Microsoft, has resulted in the takedown of criminal infrastructure powering Amadey and StealC. "The main common goal was to disrupt the 'assembly lines' cybercriminals use to launch ransomware, financial fraud, and attacks on critical infrastructure," Europol said in a statement. The development comes days after authorities from the Netherlands, Canada, Germany, and the U.S. disrupted malicious infrastructure associated with SocGholish and cleaned up nearly 15,000 infected WordPress websites. As part of the two-week-long action, cryptocurrency assets of criminal origin valued at more than $47 million have been identified, flagged, and restricted from use. In addition, as many as 27 million stolen login credentials have been recovered, and the malware distribution network has been hindered by dismantling 326 servers and 142 domains...
