Anthropic’s Claude Mythos Preview has dominated security discussions since its April 7 announcement. Early reporting describes a powerful cybersecurity-focused AI system capable of identifying vulnerabilities at scale and raising serious questions about how quickly organizations can validate, prioritize, and remediate what it finds. The debate that followed has mostly focused on the right questions: Is this a step-change or an incremental advance? Does restricting access to Microsoft, Apple, AWS, and JPMorgan actually reduce risk, or does it just concentrate defensive advantage among the already-well-defended? What happens when adversaries—state actors, criminal enterprises—build equivalent capability? These are important. But there's a quieter operational problem that's getting less airtime, and it's the one that will actually determine whether most organizations survive this shift.  The Discovery-to-Remediation Gap The Mythos announcement, and the broader AI security...

A pro-Ukrainian hacktivist group called PhantomCore has been attributed to attacks actively targeting servers running TrueConf video conferencing software in Russia since September 2025. That's according to a report published by Positive Technologies, which found the threat actors to be leveraging an exploit chain comprising three vulnerabilities to execute commands remotely on susceptible servers.     "Despite the fact that there are no exploits for this chain of vulnerability in public access, attackers from PhantomCore managed to conduct their research and reproduce vulnerabilities, which led to a large number of cases of its operation in Russian organizations," researchers Daniil Grigoryan and Georgy Khandozhko said . PhantomCore , also called Fairy Trickster, Head Mare, Rainbow Hyena, and UNG0901, is the name assigned to a politically- and financially-motivated hacking crew that has been active since 2022 following the Russo-Ukrainian war.

Cybersecurity researchers have flagged dozens of Microsoft Visual Studio Code (VS Code) extensions on the Open VSX repository that are linked to a persistent information-stealing campaign dubbed GlassWorm . The cluster of 73 extensions has been identified as cloned versions of their legitimate counterparts. Of these, six have been confirmed to be malicious, with the remaining acting as seemingly harmless sleeper packages to get users to download them and build trust, before their true intent is manifested through a subsequent update. All the extensions were published at the start of the month, per application security company Socket, which is tracking the latest iteration under the moniker GlassWorm v2 . In total, more than 320 artifacts have been identified since December 21, 2025. The list of extensions identified as malicious is listed below - outsidestormcommand.monochromator-theme keyacrosslaud.auto-loop-for-antigravity krundoven.ironplc-fast-hub boulderzitunnel.vscode-bu...

Cybersecurity researchers have disclosed details of a telecommunications fraud campaign that uses fake CAPTCHA verification tricks to dupe unsuspecting users into sending international text messages that incur charges on their mobile bills, generating illicit revenue for the threat actors who lease the phone numbers. According to a new report published by Infoblox, the operation is believed to have been active since at least June 2020, using methods like social engineering and back button hijacking in web browsers. As many as 35 phone numbers spanning 17 countries have been observed as part of the international revenue share fraud ( IRSF ) campaign. "The fake CAPTCHA has multiple steps, and each message crafted by the site is preconfigured with over a dozen phone numbers, meaning the victim isn't charged for just a single message – they're charged for sending SMSs to over 50 international destinations," researchers David Brunsdon and Darby Wise said in an analysi...

Cybersecurity researchers have discovered a new Lua-based malware created years before the notorious Stuxnet worm that aimed to sabotage Iran's nuclear program by destroying uranium enrichment centrifuges. According to a new report published by SentinelOne, the previously undocumented cyber sabotage framework dates back to 2005, primarily targeting high-precision calculation software to tamper with results. It has been codenamed fast16 . "By combining this payload with self-propagation mechanisms, the attackers aim to produce equivalent inaccurate calculations across an entire facility," researchers Vitaly Kamluk and Juan Andrés Guerrero-Saade said in an exhaustive report published this week. Fast16 is estimated to predate Stuxnet – the world's first known digital weapon designed for disruptive actions – by at least five years. While Stuxnet is widely attributed to the U.S. and Israel and later served as the architectural foundation for the Duqu information-...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added four vulnerabilities impacting SimpleHelp, Samsung MagicINFO 9 Server, and D-Link DIR-823X series routers to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The list of vulnerabilities is below - CVE-2024-57726 (CVSS score: 9.9) - A missing authorization vulnerability in SimpleHelp that could allow low-privileged technicians to create API keys with excessive permissions, which can then be used to escalate privileges to the server admin role. CVE-2024-57728 (CVSS score: 7.2) - A path traversal vulnerability in SimpleHelp that allows admin users to upload arbitrary files anywhere on the file system by uploading a crafted zip file (i.e., zip slip), which can be exploited to execute arbitrary code on the host in the context of the SimpleHelp server user. CVE-2024-7399 (CVSS score: 8.8) - A path traversal vulnerability in Samsung MagicINFO 9 Server that cou...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has revealed that an unnamed federal civilian agency's Cisco Firepower device running Adaptive Security Appliance (ASA) software was compromised in September 2025 with a new malware called FIRESTARTER . FIRESTARTER, per CISA and the U.K.'s National Cyber Security Centre (NCSC), is assessed to be a backdoor designed for remote access and control. It's believed to be deployed as part of a "widespread" campaign orchestrated by an advanced persistent threat (APT) actor to obtain access to Cisco Adaptive Security Appliance (ASA) firmware by exploiting now-patched security flaws such as - CVE-2025-20333 (CVSS score: 9.9) - An improper validation of user-supplied input vulnerability that could allow an authenticated, remote attacker with valid VPN user credentials to execute arbitrary code as root on an affected device by sending crafted HTTP requests. CVE-2025-20362 (CVSS score: 6.5) - An improper...

The Office of Inspector General (OIG) of the U.S. National Aeronautics and Space Administration (NASA) has revealed how a Chinese national posed as a U.S. researcher as part of a spear-phishing campaign to obtain sensitive information from the space agency, as well as from government entities, universities, and private companies, in violation of export control laws. "For years, NASA employees and research collaborators thought they were simply sharing software with colleagues," the OIG said in a Thursday release. "Instead, they were emailing sensitive defense technology to a Chinese national who was impersonating U.S. engineers." The individual linked to the campaign was outed as Chinese national Song Wu in September 2024, when the U.S. Department of Justice (DoJ) announced charges against him for orchestrating a multi-year phishing scheme that stretched from January 2017 to December 2021 and involved targeting dozens of U.S. professors, researchers, and engine...

The AI Agent Authority Gap - From Ungoverned to Delegation As discussed in our previous article, AI agents are exposing a structural gap in enterprise security, but the problem is often framed too narrowly. The issue is not simply that agents are new actors. It is that agents are delegated actors. They do not emerge with independent authority. They are triggered, invoked, provisioned, or empowered by existing enterprise identities: human users, machine identities, bots, service accounts, and other non-human actors. That makes Agent-AI fundamentally different from both people and software, while still being inseparable from both. This is why the AI Agent Authority Gap is really a delegation gap. Enterprises are trying to govern an emerging actor without first governing the identities that delegate authority to it. Traditional IAM was built to answer a narrower question: who has access. But once AI agents are introduced, the real question becomes: what authority is being delegated...

Cybersecurity researchers have discovered a set of malicious apps on the Apple App Store that impersonate popular cryptocurrency wallets in an attempt to steal recovery phrases and private keys since at least fall 2025. "Once launched, these apps redirect users to browser pages designed to look similar to the App Store and distribute trojanized versions of legitimate wallets," Kaspersky researcher Sergey Puzan said . "The infected apps are specifically engineered to hijack recovery phrases and private keys." The 26 apps, collectively dubbed FakeWallet , mimic various popular wallets like Bitpie, Coinbase, imToken, Ledger, MetaMask, TokenPocket, and Trust Wallet. Many of these apps have since been taken down by Apple following disclosure. There is no evidence that these apps were distributed via the Google Play Store. While malicious cryptocurrency wallets distributed in the past via bogus websites have abused iOS provisioning profiles to get users to install th...

Chinese-speaking individuals are the target of a new campaign that uses a trojanized version of SumatraPDF reader to deploy the AdaptixC2 Beacon post-exploitation agent and ultimately facilitate the abuse of Microsoft Visual Studio Code (VS Code) tunnels for remote access. Zscaler ThreatLabz, which discovered the campaign last month, has attributed it with high confidence to Tropic Trooper (aka APT23, Earth Centaur, KeyBoy, and Pirate Panda), a hacking group known for its targeting of various entities in Taiwan, Hong Kong, and the Philippines. It's assessed to be active since at least 2011. "The threat actors created a custom AdaptixC2 Beacon listener, leveraging GitHub as their command-and-control (C2) platform," security researcher Yin Hong Chang said in an analysis. It's believed that Chinese-speaking individuals in Taiwan, and individuals in South Korea and Japan, are the targets of the campaign. The starting point of the attack is a ZIP archive containing...

A high-severity security flaw in LMDeploy , an open-source toolkit for compressing, deploying, and serving large language models (LLMs), has come under active exploitation in the wild less than 13 hours after its public disclosure. The vulnerability, tracked as CVE-2026-33626 (CVSS score: 7.5), relates to a Server-Side Request Forgery (SSRF) vulnerability that could be exploited to access sensitive data. "A server-side request forgery (SSRF) vulnerability exists in LMDeploy's vision-language module," according to an advisory published by the project maintainers last week. "The load_image() function in lmdeploy/vl/utils.py fetches arbitrary URLs without validating internal/private IP addresses, allowing attackers to access cloud metadata services, internal networks, and sensitive resources." The shortcoming affects all versions of the toolkit (0.12.0 and prior) with vision language support. Orca Security researcher Igor Stepansky has been credited with disc...
