Amazon Uncovers Attacks Exploited Cisco ISE and Citrix NetScaler as Zero-Day Flaws

Nov 12, 2025Network Security / Zero-Day

Amazon's threat intelligence team on Wednesday disclosed that it observed an advanced threat actor exploiting two then-zero-day security flaws in Cisco Identity Service Engine (ISE) and Citrix NetScaler ADC products as part of attacks designed to deliver custom malware. "This discovery highlights the trend of threat actors focusing on critical identity and network access control infrastructure – the systems enterprises rely on to enforce security policies and manage authentication across their networks," CJ Moses, CISO of Amazon Integrated Security, said in a report shared with The Hacker News. The attacks were flagged by its MadPot honeypot network, with the activity weaponizing the following two vulnerabilities - CVE-2025-5777 or Citrix Bleed 2 (CVSS score: 9.3) - An insufficient input validation vulnerability in Citrix NetScaler ADC and Gateway that could be exploited by an attacker to bypass authentication.

[Webinar] Learn How Leading Security Teams Reduce Attack Surface Exposure with DASR

Nov 12, 2025Threat Detection / Risk Management

Every day, security teams face the same problem—too many risks, too many alerts, and not enough time. You fix one issue, and three more show up. It feels like you're always one step behind. But what if there was a smarter way to stay ahead—without adding more work or stress? Join The Hacker News and Bitdefender for a free cybersecurity webinar to learn about a new approach called Dynamic Attack Surface Reduction (DASR) —a method that helps security teams close gaps before attackers even find them. Most tools today only tell you what's wrong. They scan, report, and give you long lists of problems. But they don't help you fix them fast enough. The truth is, the attack surface keeps changing—new apps, cloud systems, remote devices, misconfigurations. It never stops. Attackers only need one open door. And that's why traditional defenses often fail—they react too slowly. Meet DASR: A Smarter Way to Stay Safe Dynamic Attack Surface Reduction (DASR) changes how we defend. Instead o...

Active Directory Under Siege: Why Critical Infrastructure Needs Stronger Security

Nov 12, 2025Password Security / Threat Detection

Active Directory remains the authentication backbone for  over 90% of Fortune 1000 companies. AD's importance has grown as companies adopt hybrid and cloud infrastructure, but so has its complexity. Every application, user, and device traces back to AD for authentication and authorization, making it the ultimate target. For attackers, it represents the holy grail: compromise Active Directory , and you can access the entire network. Why attackers target Active Directory  AD serves as the gatekeeper for everything in your enterprise. So, when adversaries compromise AD, they gain privileged access that lets them create accounts, modify permissions, disable security controls, and move laterally, all without triggering most alerts. The  2024 Change Healthcare breach showed what can happen when AD is compromised. In this attack, hackers exploited a server lacking multifactor authentication, pivoted to AD, escalated privileges, and then executed a highly costly cyberattac...

Google Launches 'Private AI Compute' — Secure AI Processing with On-Device-Level Privacy

Nov 12, 2025Artificial Intelligence / Encryption

Google on Tuesday unveiled a new privacy-enhancing technology called Private AI Compute to process artificial intelligence (AI) queries in a secure platform in the cloud. The company said it has built Private AI Compute to "unlock the full speed and power of Gemini cloud models for AI experiences, while ensuring your personal data stays private to you and is not accessible to anyone else, not even Google." Private AI Compute has been described as a "secure, fortified space" for processing sensitive user data in a manner that's analogous to on-device processing but with extended AI capabilities. It's powered by Trillium Tensor Processing Units (TPUs) and Titanium Intelligence Enclaves (TIE), allowing the company to use its frontier models without sacrificing on security and privacy. In other words, the privacy infrastructure is designed to take advantage of the computational speed and power of the cloud while retaining the security and privacy assuran...

WhatsApp Malware 'Maverick' Hijacks Browser Sessions to Target Brazil's Biggest Banks

Nov 11, 2025Malware / Botnet

Threat hunters have uncovered similarities between a banking malware called Coyote and a newly disclosed malicious program dubbed Maverick that has been propagated via WhatsApp. According to a report from CyberProof, both malware strains are written in .NET, target Brazilian users and banks, and feature identical functionality to decrypt, targeting banking URLs and monitor banking applications. More importantly, both include the ability to spread through WhatsApp Web . Maverick was first documented by Trend Micro early last month, attributing it to a threat actor dubbed Water Saci . The campaign involves two components: A self-propagating malware referred to as SORVEPOTEL that's spread via the desktop web version of WhatsApp and is used to deliver a ZIP archive containing the Maverick payload. The malware is designed to monitor active browser window tabs for URLs that match a hard-coded list of financial institutions in Latin America. Should the URLs match, it establishes con...

GootLoader Is Back, Using a New Font Trick to Hide Malware on WordPress Sites

Nov 11, 2025Malware / Network Security

The malware known as GootLoader has resurfaced yet again after a brief spike in activity earlier this March, according to new findings from Huntress. The cybersecurity company said it observed three GootLoader infections since October 27, 2025, out of which two resulted in hands-on keyboard intrusions with domain controller compromise taking place within 17 hours of initial infection. "GootLoader is back and now leveraging custom WOFF2 fonts with glyph substitution to obfuscate filenames," security researcher Anna Pham said , adding the malware "exploits WordPress comment endpoints to deliver XOR-encrypted ZIP payloads with unique keys per file." GootLoader, affiliated with a threat actor tracked as Hive0127 (aka UNC2565), is a JavaScript-based malware loader that's often distributed via search engine optimization (SEO) poisoning tactics to deliver additional payloads, including ransomware. In a report published last September, Microsoft revealed the th...

Npm Package Targeting GitHub-Owned Repositories Flagged as Red Team Exercise

Nov 11, 2025Software Supply Chain / Malware

Cybersecurity researchers have discovered a malicious npm package named "@acitons/artifact" that typosquats the legitimate " @actions/artifact " package with the intent to target GitHub-owned repositories. "We think the intent was to have this script execute during a build of a GitHub-owned repository, exfiltrate the tokens available to the build environment, and then use those tokens to publish new malicious artifacts as GitHub," Veracode said in an analysis. The cybersecurity company said it observed six versions of the package – from 4.0.12 to 4.0.17 – that incorporated a post-install hook to download and run malware. That said, the latest version available for download from npm is 4.0.10, indicating that the threat actor behind the package, blakesdev , has removed all the offending versions. The package was first uploaded on October 29, 2025, and has since accrued 31,398 weekly downloads. In total, it has been downloaded 47,405 times , according...

Android Trojan 'Fantasy Hub' Malware Service Turns Telegram Into a Hub for Hackers

Nov 11, 2025Cybercrime / Malware

Cybersecurity researchers have disclosed details of a new Android remote access trojan (RAT) called Fantasy Hub that's sold on Russian-speaking Telegram channels under a Malware-as-a-Service (MaaS) model. According to its seller, the malware enables device control and espionage, allowing threat actors to collect SMS messages, contacts, call logs, images, and videos, as well as intercept, reply, and delete incoming notifications. "It's a MaaS product with seller documentation, videos, and a bot-driven subscription model that helps novice attackers by providing a low barrier to entry," Zimperium researcher Vishnu Pratapagiri said in a report last week. "Because it targets financial workflows (fake windows for banks) and abuses the SMS handler role (for intercepting 2-factor SMS), it poses a direct threat to enterprise customers using BYOD and to any organization whose employees rely on mobile banking or sensitive mobile apps." The threat actor, in their...

Konni Hackers Turn Google's Find Hub into a Remote Data-Wiping Weapon

Nov 10, 2025Cyber Espionage / Threat Intelligence

The North Korea-affiliated threat actor known as Konni (aka Earth Imp, Opal Sleet, Osmium, TA406, and Vedalia) has been attributed to a new set of attacks targeting both Android and Windows devices for data theft and remote control. "Attackers impersonated psychological counselors and North Korean human rights activists, distributing malware disguised as stress-relief programs," the Genians Security Center (GSC) said in a technical report. What's notable about the attacks targeting Android devices is also the destructive ability of the threat actors to exploit Google's asset tracking services Find Hub (formerly Find My Device) to remotely reset victim devices, thereby leading to the unauthorized deletion of personal data. The activity was detected in early September 2025. The development marks the first time the hacking group has weaponized legitimate management functions to remotely reset mobile devices. The activity is also preceded by an attack chain in whic...
