VolkLocker Ransomware Exposed by Hard-Coded Master Key Allowing Free Decryption

VolkLocker Ransomware Exposed by Hard-Coded Master Key Allowing Free Decryption

Dec 15, 2025 Ransomware / Cybercrime
The pro-Russian hacktivist group known as CyberVolk (aka GLORIAMIST) has resurfaced with a new ransomware-as-a-service (RaaS) offering called VolkLocker that suffers from implementation lapses in test artifacts, allowing users to decrypt files without paying an extortion fee. According to SentinelOne, VolkLocker (aka CyberVolk 2.x) emerged in August 2025 and is capable of targeting both Windows and Linux systems. It's written in Golang. "Operators building new VolkLocker payloads must provide a bitcoin address, Telegram bot token ID, Telegram chat ID, encryption deadline, desired file extension, and self-destruct options," security researcher Jim Walter said in a report published last week. Once launched, the ransomware attempts to escalate privileges, performs reconnaissance and system enumeration, including checking local MAC address prefixes against known virtualization vendors like Oracle and VMware. In the next stage, it lists all available drives and determin...

Dec 11, 2025 Cyber Espionage / Windows Security
Cybersecurity researchers have disclosed details of a new fully-featured Windows backdoor called NANOREMOTE that uses the Google Drive API for command-and-control (C2) purposes. According to a report from Elastic Security Labs, the malware shares code similarities with another implant codenamed FINALDRAFT (aka Squidoor) that employs Microsoft Graph API for C2. FINALDRAFT is attributed to a threat cluster known as REF7707 (aka CL-STA-0049, Earth Alux, and Jewelbug). "One of the malware's primary features is centered around shipping data back and forth from the victim endpoint using the Google Drive API," Daniel Stepanic, principal security researcher at Elastic Security Labs, said. "This feature ends up providing a channel for data theft and payload staging that is difficult for detection. The malware includes a task management system used for file transfer capabilities that include queuing download/upload tasks, pausing/resuming file transfers, canceling file...

Microsoft Uncovers 'Whisper Leak' Attack That Identifies AI Chat Topics in Encrypted Traffic

Microsoft Uncovers 'Whisper Leak' Attack That Identifies AI Chat Topics in Encrypted Traffic

Nov 08, 2025 Network Security / Data Protection
Microsoft has disclosed details of a novel side-channel attack targeting remote language models that could enable a passive adversary with capabilities to observe network traffic to glean details about model conversation topics despite encryption protections under certain circumstances. This leakage of data exchanged between humans and streaming-mode language models could pose serious risks to the privacy of user and enterprise communications, the company noted. The attack has been codenamed Whisper Leak . "Cyber attackers in a position to observe the encrypted traffic (for example, a nation-state actor at the internet service provider layer, someone on the local network, or someone connected to the same Wi-Fi router) could use this cyber attack to infer if the user's prompt is on a specific topic," security researchers Jonathan Bar Or and Geoff McDonald, along with the Microsoft Defender Security Research Team, said . Put differently, the attack allows an attacker t...
A New Security Layer for macOS Takes Aim at Admin Errors Before Hackers Do

A New Security Layer for macOS Takes Aim at Admin Errors Before Hackers Do

Oct 31, 2025 Endpoint Security / Network Security
A design firm is editing a new campaign video on a MacBook Pro. The creative director opens a collaboration app that quietly requests microphone and camera permissions. MacOS is supposed to flag that, but in this case, the checks are loose. The app gets access anyway. On another Mac in the same office, file sharing is enabled through an old protocol called SMB version one. It's fast and convenient—but outdated and vulnerable. Attackers can exploit it in minutes if the endpoint is exposed to the internet. These are the kinds of configuration oversights that happen every day, even in organizations that take security seriously. They're not failures of hardware or antivirus software. They're configuration gaps that open doors to attackers, and they often go unnoticed because nobody is looking for them. That's where Defense Against Configurations (DAC) comes in. Misconfigurations are a gift to attackers: default settings left open, remote access that should be off (like outdated netwo...
New TEE.Fail Side-Channel Attack Extracts Secrets from Intel and AMD DDR5 Secure Enclaves

New TEE.Fail Side-Channel Attack Extracts Secrets from Intel and AMD DDR5 Secure Enclaves

Oct 28, 2025 Encryption / Hardware Security
A group of academic researchers from Georgia Tech, Purdue University, and Synkhronix have developed a side-channel attack called TEE.Fail that allows for the extraction of secrets from the trusted execution environment (TEE) in a computer's main processor, including Intel's Software Guard eXtensions (SGX) and Trust Domain Extensions (TDX) and AMD's Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP) and Ciphertext Hiding . The attack, at its core, involves the use of an interposition device built using off-the-shelf electronic equipment that costs under $1,000 and makes it possible to physically inspect all memory traffic inside a DDR5 server. "This allows us for the first time to extract cryptographic keys from Intel TDX and AMD SEV-SNP with Ciphertext Hiding, including in some cases secret attestation keys from fully updated machines in trusted status," the researchers noted on an informational site. "Beyond breaking CPU-based TEEs, we...

New WireTap Attack Extracts Intel SGX ECDSA Key via DDR4 Memory-Bus Interposer

New WireTap Attack Extracts Intel SGX ECDSA Key via DDR4 Memory-Bus Interposer

Oct 01, 2025 Encryption / Hardware Security
In yet another piece of research, academics from Georgia Institute of Technology and Purdue University have demonstrated that the security guarantees offered by Intel's Software Guard eXtensions (SGX) can be bypassed on DDR4 systems to passively decrypt sensitive data. SGX is designed as a hardware feature in Intel server processors that allows applications to be run in a Trusted Execution Environment (TEE). It essentially isolates trusted code and resources within what's called enclaves, preventing attackers from viewing their memory or CPU state.  In doing so, the mechanism ensures that the data stays confidential even when the underlying operating system has been tampered with or compromised by other means. However, the latest findings show the limitations of SGX. "We show how one can build a device to physically inspect all memory traffic inside a computer cheaply and easily, in environments with only basic electrical tools, and using equipment easily purchased on...
New $50 Battering RAM Attack Breaks Intel and AMD Cloud Security Protections

New $50 Battering RAM Attack Breaks Intel and AMD Cloud Security Protections

Sep 30, 2025 Hardware Security / Encryption
A group of academics from KU Leuven and the University of Birmingham has demonstrated a new vulnerability called Battering RAM to bypass the latest defenses on Intel and AMD cloud processors. "We built a simple, $50 interposer that sits quietly in the memory path, behaving transparently during startup and passing all trust checks," researchers Jesse De Meulemeester, David Oswald, Ingrid Verbauwhede, and Jo Van Bulck said on a website publicizing the findings. "Later, with just a flip of a switch, our interposer turns malicious and silently redirects protected addresses to attacker-controlled locations, allowing corruption or replay of encrypted memory." Battering RAM compromises Intel's Software Guard Extensions ( SGX ) and AMD's Secure Encrypted Virtualization with Secure Nested Paging ( SEV-SNP ) hardware security features, which ensure that customer data remains encrypted in memory and protected during use. It affects all systems using DDR4 memory...

From Quantum Hacks to AI Defenses – Expert Guide to Building Unbreakable Cyber Resilience

Sep 17, 2025 Cyber Resilience / Webinar
Quantum computing and AI working together will bring incredible opportunities. Together, the technologies will help us extend innovation further and faster than ever before. But, imagine the flip side, waking up to news that hackers have used a quantum computer to crack your company's encryption overnight, exposing your most sensitive data, rendering much of it untrustworthy. And with your sensitive data exposed, where does that leave trust from your customers? And the cost to mitigate - if that is even possible with your outdated pre-quantum systems? According to IBM, cyber breaches are already hitting businesses with an average of $4.44 million per incident, and as high as $10.22 million in the US, but with quantum and AI working simultaneously, experts warn it could go much higher. In 2025, nearly two-thirds of organizations see quantum computing as the biggest cybersecurity threat looming in the next 3-5 years, while 93% of security leaders are prepping for daily AI-driven a...
Senator Wyden Urges FTC to Probe Microsoft for Ransomware-Linked Cybersecurity Negligence

Senator Wyden Urges FTC to Probe Microsoft for Ransomware-Linked Cybersecurity Negligence

Sep 11, 2025 Critical Infrastructure / Ransomware
U.S. Senator Ron Wyden has called on the Federal Trade Commission (FTC) to probe Microsoft and hold it responsible for what he called "gross cybersecurity negligence" that enabled ransomware attacks on U.S. critical infrastructure, including against healthcare networks. "Without timely action, Microsoft's culture of negligent cybersecurity, combined with its de facto monopolization of the enterprise operating system market, poses a serious national security threat and makes additional hacks inevitable," Wyden wrote in a four-page letter to FTC Chairman Andrew Ferguson, likening Redmond to an "arsonist selling firefighting services to their victims." The development comes after Wyden's office obtained new information from healthcare system Ascension, which suffered a crippling ransomware attack last year, resulting in the theft of personal and medical information associated with nearly 5.6 million individuals . The ransomware attack, which al...
GPUGate Malware Uses Google Ads and Fake GitHub Commits to Target IT Firms

GPUGate Malware Uses Google Ads and Fake GitHub Commits to Target IT Firms

Sep 08, 2025 Malvertising / Encryption
Cybersecurity researchers have detailed a new sophisticated malware campaign that leverages paid ads on search engines like Google to deliver malware to unsuspecting users looking for popular tools like GitHub Desktop. While malvertising campaigns have become commonplace in recent years, the latest activity gives it a little twist of its own: Embedding a GitHub commit into a page URL containing altered links that point to attacker-controlled infrastructure. "Even when a link seems to point to a reputable platform such as GitHub, the underlying URL can be manipulated to resolve to a counterfeit site," Arctic Wolf said in a report published last week. Exclusively targeting IT and software development companies within Western Europe since at least December 2024, the links within the rogue GitHub commit are designed to funnel users to a malicious download hosted on a lookalike domain ("gitpage[.]app"). The activity was first detected on August 19, 2025. The first...
