Cybersecurity researchers have warned of a new campaign that's leveraging a variant of the FileFix social engineering tactic to deliver the StealC information stealer malware. "The observed campaign uses a highly convincing, multilingual phishing site (e.g., fake Facebook Security page), with anti-analysis techniques and advanced obfuscation to evade detection," Acronis security researcher Eliad Kimhy said in a report shared with The Hacker News. At a high level, the attack chain involves the use of FileFix to entice users into launching an initial payload that then proceeds to download seemingly innocuous images containing the malicious components from a Bitbucket repository. This allows the attackers to abuse the trust associated with a legitimate source code hosting platform to bypass detection. FileFix, first documented by security researcher mrd0x as a proof-of-concept (PoC) in June 2025, is a little different from ClickFix in that it eschews the need for us...

Apple on Monday backported fixes for a recently patched security flaw that has been actively exploited in the wild. The vulnerability in question is CVE-2025-43300 (CVSS score: 8.8), an out-of-bounds write issue in the ImageIO component that could result in memory corruption when processing a malicious image file. "Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals," the company said. Since then, WhatsApp has acknowledged that a vulnerability in its messaging apps for Apple iOS and macOS (CVE-2025-55177, CVSS score: 5.4) had been chained with CVE-2025-43300 as part of highly-targeted spyware attacks aimed at less than 200 individuals. While the shortcoming was first addressed by the iPhone maker late last month with the release of iOS 18.6.2 and iPadOS 18.6.2, iPadOS 17.7.10, macOS Ventura 13.7.8, macOS Sonoma 14.7.8, and macOS Sequoia 15.6.1, it has also been released for the f...

AI agents are rapidly becoming a core part of the enterprise, being embedded across enterprise workflows, operating with autonomy, and making decisions about which systems to access and how to use them. But as agents grow in power and autonomy, so do the risks and threats.  Recent studies show 80% of companies have already experienced unintended AI agent actions, from unauthorized system access to data leaks. These incidents aren’t edge cases. They are the inevitable outcome of deploying AI agents at scale without purpose-built security mechanisms. Traditional IAM wasn’t designed for this. Agents move too fast, operate 24/7, while relying on non-human identities (NHIs) to define precisely what they can and can’t do. How can organizations possibly secure what they cannot see or control? To address this challenge, a new approach is needed—one that enables secure-by-design AI agent deployment across the enterprise. Enter: Astrix’s Agent Control Plane (ACP) Astrix’s AI Agent Cont...

A team of academics from ETH Zürich and Google has discovered a new variant of a RowHammer attack targeting Double Data Rate 5 (DDR5) memory chips from South Korean semiconductor vendor SK Hynix. The RowHammer attack variant, codenamed Phoenix ( CVE-2025-6202 , CVSS score: 7.1), is capable of bypassing sophisticated protection mechanisms put in place to resist the attack. "We have proven that reliably triggering RowHammer bit flips on DDR5 devices from SK Hynix is possible on a larger scale," ETH Zürich said. "We also proved that on-die ECC does not stop RowHammer, and RowHammer end-to-end attacks are still possible with DDR5." RowHammer refers to a hardware vulnerability where repeated access of a row of memory in a DRAM chip can trigger bit flips in adjacent rows, resulting in data corruption. This can be subsequently weaponized by bad actors to gain unauthorized access to data, escalate privileges, or even cause a denial-of-service. Although first demo...

Cybersecurity researchers have flagged a fresh software supply chain attack targeting the npm registry that has affected more than 40 packages that belong to multiple maintainers. "The compromised versions include a function (NpmModule.updatePackage) that downloads a package tarball, modifies package.json, injects a local script (bundle.js), repacks the archive, and republishes it, enabling automatic trojanization of downstream packages," supply chain security company Socket said . The end goal of the campaign is to search developer machines for secrets using TruffleHog's credential scanner and transmit them to an external server under the attacker's control. The attack is capable of targeting both Windows and Linux systems. The following packages have been identified as impacted by the incident - angulartics2@14.1.2 @ctrl/deluge@7.2.2 @ctrl/golang-template@1.4.3 @ctrl/magnet-link@4.0.4 @ctrl/ngx-codemirror@7.0.2 @ctrl/ngx-csv@6.0.2 @ctrl/ngx-emoji-mart@...

The China-aligned threat actor known as Mustang Panda has been observed using an updated version of a backdoor called TONESHELL and a previously undocumented USB worm called SnakeDisk. "The worm only executes on devices with Thailand-based IP addresses and drops the Yokai backdoor," IBM X-Force researchers Golo Mühr and Joshua Chung said in an analysis published last week. The tech giant's cybersecurity division is tracking the cluster under the name Hive0154, which is also broadly referred to as BASIN, Bronze President, Camaro Dragon, Earth Preta, HoneyMyte, Polaris, RedDelta, Stately Taurus, and Twill Typhoon. The state-sponsored threat actor is believed to have been active since at least 2012. TONESHELL was first publicly documented by Trend Micro way back in November 2022 as part of cyber attacks targeting Myanmar, Australia, the Philippines, Japan, and Taiwan between May and October. Typically executed via DLL side-loading, its primary responsibility is to d...

Attacks that target users in their web browsers have seen an unprecedented rise in recent years. In this article, we’ll explore what a “browser-based attack” is, and why they’re proving to be so effective.  What is a browser-based attack? First, it’s important to establish what a browser-based attack is. In most scenarios, attackers don’t think of themselves as attacking your web browser. Their end-goal is to compromise your business apps and data. That means going after the third-party services that are now the backbone of business IT. The most common attack path today sees attackers log into third-party services, dump the data, and monetize it through extortion. You need only look at last year’s Snowflake customer breaches or the still-ongoing Salesforce attacks to see the impact.  The most logical way to do this is by targeting users of those apps. And because of the changes to working practices, your users are more accessible than ever to external attackers — and ex...

A new artificial intelligence (AI)-powered penetration testing tool linked to a China-based company has attracted nearly 11,000 downloads on the Python Package Index (PyPI) repository, raising concerns that it could be repurposed by cybercriminals for malicious purposes. Dubbed Villager, the framework is assessed to be the work of Cyberspike, which has positioned the tools as a red teaming solution to automate testing workflows. The package was first uploaded to PyPI in late July 2025 by a user named stupidfish001, a former capture the flag (CTF) player for the Chinese HSCSEC team. "The rapid, public availability and automation capabilities create a realistic risk that Villager will follow the Cobalt Strike trajectory: commercially or legitimately developed tooling becoming widely adopted by threat actors for malicious campaigns," Straiker researchers Dan Regalado and Amanda Rousseau said in a report shared with The Hacker News. The emergence of Villager comes shortly ...

Chinese-speaking users are the target of a search engine optimization (SEO) poisoning campaign that uses fake software sites to distribute malware. "The attackers manipulated search rankings with SEO plugins and registered lookalike domains that closely mimicked legitimate software sites," Fortinet FortiGuard Labs researcher Pei Han Liao said . "By using convincing language and small character substitutions, they tricked victims into visiting spoofed pages and downloading malware." The activity, which was discovered by the cybersecurity company in August 2025, leads to the deployment of malware families like HiddenGh0st and Winos (aka ValleyRAT), both of which are variants of a remote access trojan called Gh0st RAT. It's worth noting that the use of Winos has been attributed to a cybercrime group known as Silver Fox , which is also tracked as SwimSnake, The Great Thief of Valley (or Valley Thief), UTG-Q-1000, and Void Arachne. It's believed to be acti...

The U.S. Federal Bureau of Investigation (FBI) has issued a flash alert to release indicators of compromise (IoCs) associated with two cybercriminal groups tracked as UNC6040 and UNC6395 for orchestrating a string of data theft and extortion attacks. "Both groups have recently been observed targeting organizations' Salesforce platforms via different initial access mechanisms," the FBI said . UNC6395 is a threat group that has been attributed a widespread data theft campaign targeting Salesforce instances in August 2025 by exploiting compromised OAuth tokens for the Salesloft Drift application. In an update issued this week, Salesloft said the attack was made possible due to the breach of its GitHub account from March through June 2025. As a result of the breach, Salesloft has isolated the Drift infrastructure and taken the artificial intelligence (AI) chatbot application offline. The company also said it's in the process of implementing new multi-factor auth...

Samsung has released its monthly security updates for Android, including a fix for a security vulnerability that it said has been exploited in zero-day attacks. The vulnerability, CVE-2025-21043 (CVSS score: 8.8), concerns an out-of-bounds write that could result in arbitrary code execution. "Out-of-bounds Write in libimagecodec.quram.so prior to SMR Sep-2025 Release 1 allows remote attackers to execute arbitrary code," Samsung said in an advisory. "The patch fixed the incorrect implementation." According to a 2020 report from Google Project Zero, libimagecodec.quram.so is a closed-source image parsing library developed by Quramsoft that implements support for various image formats.
