Silver Fox Expands Asia Cyber Campaign with AtlasCross RAT and Fake Domains

Silver Fox Expands Asia Cyber Campaign with AtlasCross RAT and Fake Domains

Mar 31, 2026 Malware / Encryption
Chinese-speaking users are the target of an active campaign that uses typosquatted domains impersonating trusted software brands to deliver a previously undocumented remote access trojan named AtlasCross RAT . "The operation covers VPN clients, encrypted messengers, video conferencing tools, cryptocurrency trackers, and e-commerce applications, with eleven confirmed delivery domains impersonating brands including Surfshark VPN, Signal, Telegram, Zoom, Microsoft Teams, and others," Germany-based cybersecurity company Hexastrike said in a report published last week. The activity has been attributed to a Chinese cybercrime group called Silver Fox , which is also tracked as SwimSnake, The Great Thief of Valley (or Valley Thief), UTG-Q-1000, and Void Arachne. The discovery of AtlasCross RAT represents an evolution of the threat actor's arsenal from Gh0st RAT derivatives like ValleyRAT (aka Winos 4.0), Gh0stCringe, and HoldingHands RAT (aka Gh0stBins). The attack chains i...
Speagle Malware Hijacks Cobra DocGuard to Steal Data via Compromised Servers

Speagle Malware Hijacks Cobra DocGuard to Steal Data via Compromised Servers

Mar 19, 2026 Cyber Espionage / Threat Intelligence
Cybersecurity researchers have flagged a new malware dubbed Speagle that hijacks the functionality and infrastructure of a legitimate program called Cobra DocGuard. "Speagle is designed to surreptitiously harvest sensitive information from infected computers and transmit it to a Cobra DocGuard server that has been compromised by the attackers, masking the data exfiltration process as legitimate communications between client and server," Symantec and Carbon Black researchers said in a report published today. Cobra DocGuard is a document security and encryption platform developed by EsafeNet. The abuse of this software in real-world attacks has been publicly recorded twice to date. In January 2023, ESET documented an intrusion where a gambling company in Hong Kong was compromised in September 2022 via a malicious update pushed by the software. Later that August, Symantec highlighted the activity of a new threat cluster codenamed Carderbee, which was found using a trojan...
Meta to Shut Down Instagram End-to-End Encrypted Chat Support Starting May 2026

Meta to Shut Down Instagram End-to-End Encrypted Chat Support Starting May 2026

Mar 13, 2026 Encryption / Data Protection
Meta has announced plans to discontinue support for end-to-end encryption (E2EE) for chats on Instagram after May 8, 2026. "If you have chats that are impacted by this change, you will see instructions on how you can download any media or messages you may want to keep," the social media giant said in a help document. "If you're on an older version of Instagram, you may also need to update the app before you can download your affected chats." When reached for comment, this is what Meta had to say: "Very few people were opting in to end-to-end encrypted messaging in DMs, so we're removing this option from Instagram in the coming months. Anyone who wants to keep messaging with end-to-end encryption can easily do that on WhatsApp." The American company first began testing E2EE for Instagram direct messages in 2021 as part of CEO Mark Zuckerberg's "privacy-focused vision for social networking." The feature is currently " only ...

How to Scale Phishing Detection in Your SOC: 3 Steps for CISOs

How to Scale Phishing Detection in Your SOC: 3 Steps for CISOs

Mar 12, 2026 Malware Analysis / Threat Intelligence
Phishing has quietly turned into one of the hardest enterprise threats to expose early. Instead of crude lures and obvious payloads, modern campaigns rely on trusted infrastructure, legitimate-looking authentication flows, and encrypted traffic that conceals malicious behavior from traditional detection layers. For CISOs, the priority is now clear: scale phishing detection in a way that helps the SOC uncover real risk before it becomes credential theft, business interruption, and board-level fallout. Why Scaling Phishing Detection Has Become a Priority for Modern SOCs For many security teams, phishing is no longer a single alert to investigate — it is a continuous stream of suspicious links, login attempts, and user-reported messages that must be validated quickly. The problem is that most SOC workflows were never designed to handle this volume. Each investigation still requires time, context gathering, and manual validation, while attackers operate at machine speed. When phishing ...
Preparing for the Quantum Era: Post-Quantum Cryptography Webinar for Security Leaders

Preparing for the Quantum Era: Post-Quantum Cryptography Webinar for Security Leaders

Mar 05, 2026 Encryption / Data Protection
Most organizations assume encrypted data is safe. But many attackers are already preparing for a future where today’s encryption can be broken. Instead of trying to decrypt information now, they are collecting encrypted data and storing it so it can be decrypted later using quantum computers. This tactic—known as “harvest now, decrypt later” —means sensitive data transmitted today could become readable years from now once quantum capabilities mature. Security leaders who want to understand this risk and how to prepare can explore it in detail in the upcoming webinar on Post-Quantum Cryptography best practices , where experts will explain practical ways organizations can begin protecting data before quantum decryption becomes possible. Why Post-Quantum Cryptography Matters Quantum computing is advancing quickly, and most modern encryption algorithms, such as RSA and ECC, will not remain secure forever. For organizations that must keep data confidential for many years—financial r...
