NVIDIA is urging customers to enable System-level Error Correction Codes (ECC) as a defense against a variant of a RowHammer attack demonstrated against its graphics processing units (GPUs). "Risk of successful exploitation from RowHammer attacks varies based on DRAM device, platform, design specification, and system settings," the GPU maker said in an advisory released this week. Dubbed GPUHammer , the attacks mark the first-ever RowHammer exploit demonstrated against NVIDIA's GPUs (e.g., NVIDIA A6000 GPU with GDDR6 Memory), causing malicious GPU users to tamper with other users' data by triggering bit flips in GPU memory. The most concerning consequence of this behavior, University of Toronto researchers found, is the degradation of an artificial intelligence (AI) model's accuracy from 80% to less than 1%. RowHammer is to modern DRAMs just like how Spectre and Meltdown are to contemporary CPUs. While both are hardware-level security vulnerabilities, Row...

Cybersecurity researchers have discovered a serious security issue that allows leaked Laravel APP_KEYs to be weaponized to gain remote code execution capabilities on hundreds of applications. "Laravel's APP_KEY, essential for encrypting sensitive data, is often leaked publicly (e.g., on GitHub)," GitGuardian said . "If attackers get access to this key, they can exploit a deserialization flaw to execute arbitrary code on the server – putting data and infrastructure at risk." The company, in collaboration with Synacktiv, said it was able to extract more than 260,000 APP_KEYs from GitHub from 2018 to May 30, 2025, identifying over 600 vulnerable Laravel applications in the process. GitGuardian said it observed over 10,000 unique APP_KEYs across GitHub, of which 400 APP_KEYs were validated as functional. APP_KEY is a random 32-byte encryption key that's generated during the installation of Laravel. Stored in the .env file of the application, it's used ...

Cybersecurity researchers have discovered a set of four security flaws in OpenSynergy's BlueSDK Bluetooth stack that, if successfully exploited, could allow remote code execution on millions of transport vehicles from different vendors. The vulnerabilities, dubbed PerfektBlue , can be fashioned together as an exploit chain to run arbitrary code on cars from at least three major automakers, Mercedes-Benz, Volkswagen, and Skoda, according to PCA Cyber Security (formerly PCAutomotive). Outside of these three, a fourth unnamed original equipment manufacturer (OEM) has been confirmed to be affected as well. "PerfektBlue exploitation attack is a set of critical memory corruption and logical vulnerabilities found in OpenSynergy BlueSDK Bluetooth stack that can be chained together to obtain Remote Code Execution (RCE)," the cybersecurity company said . While infotainment systems are often seen as isolated from critical vehicle controls, in practice, this separation depends he...

A recently disclosed maximum-severity security flaw impacting the Wing FTP Server has come under active exploitation in the wild, according to Huntress. The vulnerability, tracked as CVE-2025-47812 (CVSS score: 10.0), is a case of improper handling of null ('\0') bytes in the server's web interface, which allows for remote code execution. It has been addressed in version 7.4.4. "The user and admin web interfaces mishandle '\0' bytes, ultimately allowing injection of arbitrary Lua code into user session files," according to an advisory for the flaw on CVE.org. "This can be used to execute arbitrary system commands with the privileges of the FTP service (root or SYSTEM by default)." What makes it even more concerning is that the flaw can be exploited via anonymous FTP accounts. A comprehensive breakdown of the vulnerability entered the public domain towards the end of June 2025, courtesy of RCE Security researcher Julien Ahrens. Cybersecuri...

An Iranian-backed ransomware-as-a-service (RaaS) named Pay2Key has resurfaced in the wake of the Israel-Iran-U.S. conflict last month, offering bigger payouts to cybercriminals who launch attacks against Israel and the U.S. The financially motivated scheme, now operating under the moniker Pay2Key.I2P, is assessed to be linked to a hacking group tracked as Fox Kitten (aka Lemon Sandstorm). "Linked to the notorious Fox Kitten APT group and closely tied to the well-known Mimic ransomware, [...] Pay2Key.I2P appears to partner with or incorporate Mimic's capabilities," Morphisec security researcher Ilia Kulmin said . "Officially, the group offers an 80% profit share (up from 70%) to affiliates supporting Iran or participating in attacks against the enemies of Iran, signaling their ideological commitment." Last year, the U.S. government revealed the advanced persistent threat's (APT) modus operandi of carrying out ransomware attacks by covertly partnering wi...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a critical security flaw impacting Citrix NetScaler ADC and Gateway to its Known Exploited Vulnerabilities ( KEV ) catalog, officially confirming the vulnerability has been weaponized in the wild. The shortcoming in question is CVE-2025-5777 (CVSS score: 9.3), an instance of insufficient input validation that could be exploited by an attacker to bypass authentication when the appliance is configured as a Gateway or AAA virtual server. It's also called Citrix Bleed 2 owing to its similarities with Citrix Bleed (CVE-2023-4966).

It acts as a local proxy, enabling MCP clients like Claude Desktop to communicate with remote MCP servers, as opposed to running them locally on the same...

Cryptocurrency users are the target of an ongoing social engineering campaign that employs fake startup companies to trick users into downloading malware that can drain digital assets from both Windows and macOS systems. "These malicious operations impersonate AI, gaming, and Web3 firms using spoofed social media accounts and project documentation hosted on legitimate platforms like Notion and GitHub," Darktrace researcher Tara Gould said in a report shared with The Hacker News. The elaborate social media scam has been for sometime now, with a previous iteration in December 2024 leveraging bogus videoconferencing platforms to dupe victims into joining a meeting under the pretext of discussing an investment opportunity after approaching them on messaging apps like Telegram. Users who ended up downloading the purported meeting software were stealthily infected by stealer malware such as Realst. The campaign was codenamed Meeten by Cado Security (which was acquired by Dark...

The U.K. National Crime Agency (NCA) on Thursday announced that four people have been arrested in connection with cyber attacks targeting major retailers Marks & Spencer, Co-op, and Harrods. The arrested individuals include two men aged 19, a third aged 17, and a 20-year-old woman.

Generative AI is not arriving with a bang, it's slowly creeping into the software that companies already use on a daily basis. Whether it is video conferencing or CRM, vendors are scrambling to integrate AI copilots and assistants into their SaaS applications. Slack can now provide AI summaries of chat threads, Zoom can provide meeting summaries, and office suites such as Microsoft 365 contain AI assistance in writing and analysis. This trend of AI usage implies that the majority of businesses are awakening to a new reality: AI capabilities have spread across their SaaS stack overnight, with no centralized control. A recent survey found 95% of U.S. companies are now using generative AI, up massively in just one year. Yet this unprecedented usage comes tempered by growing anxiety. Business leaders have begun to worry about where all this unseen AI activity might lead. Data security and privacy have quickly emerged as top concerns, with many fearing that sensitive information could le...
