The U.K. National Cyber Security Centre (NCSC) has revealed that threat actors have exploited the recently disclosed security flaws impacting Cisco firewalls as part of zero-day attacks to deliver previously undocumented malware families like RayInitiator and LINE VIPER . "The RayInitiator and LINE VIPER malware represent a significant evolution on that used in the previous campaign, both in sophistication and its ability to evade detection," the agency said . Cisco on Thursday revealed that it began investigating attacks on multiple government agencies linked to the state-sponsored campaign in May 2025 that targeted Adaptive Security Appliance (ASA) 5500-X Series devices to implant malware, execute commands, and potentially exfiltrate data from the compromised devices. An in-depth analysis of firmware extracted from the infected devices running Cisco Secure Firewall ASA Software with VPN web services enabled ultimately led to the discovery of a memory corruption bug in...

Cisco is urging customers to patch two security flaws impacting the VPN web server of Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Cisco Secure Firewall Threat Defense (FTD) Software, which it said have been exploited in the wild. The zero-day vulnerabilities in question are listed below - CVE-2025-20333 (CVSS score: 9.9) - An improper validation of user-supplied input in HTTP(S) requests 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 validation of user-supplied input in HTTP(S) requests vulnerability that could allow an unauthenticated, remote attacker to access restricted URL endpoints without authentication by sending crafted HTTP requests Cisco said it's aware of "attempted exploitation" of both vulnerabilities, but did not reveal who may be behind it, ...

Welcome to this week’s Threatsday Bulletin —your Thursday check-in on the latest twists and turns in cybersecurity and hacking. The digital threat landscape never stands still. One week it’s a critical zero-day, the next it’s a wave of phishing lures or a state-backed disinformation push. Each headline is a reminder that the rules keep changing and that defenders—whether you’re protecting a global enterprise or your own personal data—need to keep moving just as fast. In this edition we unpack fresh exploits, high-profile arrests, and the newest tactics cybercriminals are testing right now. Grab a coffee, take five minutes, and get the key insights that help you stay a step ahead of the next breach. Firmware fights back SonicWall Releases SMA 100 Firmware Update to Remove Rootkit SonicWall has released a firmware update that it said will help customers remove rootkit malware deployed in attacks targeting SMA 100 series devices. "S...

The threat actor known as Vane Viper has been outed as a purveyor of malicious ad technology (adtech), while relying on a tangled web of shell companies and opaque ownership structures to deliberately evade responsibility. "Vane Viper has provided core infrastructure in widespread malvertising, ad fraud, and cyberthreat proliferation for at least a decade," Infoblox said in a technical report published last week in collaboration with Guardio and Confiant. "Vane Viper not only brokers traffic for malware droppers and phishers, but appears to run their own campaigns, consistent with previously documented ad-fraud techniques." Vane Viper, also called Omnatuor , was previously documented by the DNS threat intelligence firm in August 2022, describing it as a malvertising network akin to VexTrio Viper that takes advantage of vulnerable WordPress sites to build a massive network of compromised domains and use them to spread riskware, spyware, and adware. One of t...

Cybersecurity researchers have disclosed a critical flaw impacting Salesforce Agentforce , a platform for building artificial intelligence (AI) agents, that could allow attackers to potentially exfiltrate sensitive data from its customer relationship management (CRM) tool by means of an indirect prompt injection. The vulnerability has been codenamed ForcedLeak (CVSS score: 9.4) by Noma Security, which discovered and reported the problem on July 28, 2025. It impacts any organization using Salesforce Agentforce with the Web-to-Lead functionality enabled. "This vulnerability demonstrates how AI agents present a fundamentally different and expanded attack surface compared to traditional prompt-response systems," Sasi Levi, security research lead at Noma, said in a report shared with The Hacker News. One of the most severe threats facing generative artificial intelligence (GenAI) systems today is indirect prompt injection , which occurs when malicious instructions are ins...
