What Is End Point Security And How Does It Work?

Endpoint security is a suite of technologies and processes designed to protect devices connected to a business network from cyber threats. It includes various devices such as laptops, smartphones, tablets, servers, and IoT devices. Endpoint security employs a multi-layered approach, scanning for malware, regulating applications, and monitoring device activity for unusual behavior. It is distinct from antivirus software, encompassing a broader range of protective measures, including firewalls, encryption, application controls, patch management, and Endpoint Detection and Response (EDR). The rise of remote work and the increasing number of devices create a larger attack surface, making endpoint security essential for preventing breaches and safeguarding business operations.

NetScaler vulnerability exploited, AdaptHealth suffers breach, new Android malware

The Cybersecurity and Infrastructure Security Agency (CISA) warned of a critical vulnerability in NetScaler, identified as CVE-2026-19490, with a CVSS score of 9.3, which has been exploited and affects all NetScaler ADC and Gateway appliances. Citrix has patched this vulnerability as of August 19. AdaptHealth reported a data breach affecting over 4.1 million individuals, compromising personal, health, and insurance information, but not Social Security numbers or financial data. A new strain of Android malware, MantaxOtax, attributed to Indonesian threat actors, combines ransomware and spyware, stealing sensitive information and affecting older Android versions. The Gigabud banking trojan has evolved to evade detection by installing a secondary app that hides the malicious application. CISA acting director Nick Andersen emphasized the need for swift adaptation to cybersecurity threats and highlighted staffing improvements within CISA. Russian e-commerce giant Wildberries experienced disruptions from a DDoS attack affecting payments to sellers, following claims of a cyber operation by Ukraine's military intelligence. McKesson faced a cyberattack exposing sensitive data of 6.4 million individuals, with the ShinyHunters group releasing this data after a failed extortion attempt. IDScan confirmed a data breach affecting 150 million individuals, resulting in the theft of personally identifiable information and government-issued documents.

That April Windows update you skipped? Hackers are exploiting it now

Timely updates are crucial for home users to protect personal data and device integrity. Organizations should assess systems for vulnerabilities, especially those accessible via the internet. CVE-2026-33824 is a critical vulnerability in the Internet Key Exchange (IKE) service extensions within Windows, caused by a “double-free” error, allowing code execution. It affects various versions of Windows 10, Windows 11, and Windows Server, and is included in the CISA KEV catalog. Users are urged to install the April Windows updates immediately. CVE-2026-55040 is a critical vulnerability in Microsoft SharePoint that allows unauthenticated attackers to bypass a key security feature, with a CVSS score of 9.1. It affects SharePoint Enterprise Server 2016, SharePoint Server 2019, and the Subscription Edition, with fixed builds already available.

‘This one just needs a script’: Researchers find ultimate Windows kill switch which can disable antivirus with almost no user interaction

Researchers have identified a significant vulnerability in consumer DDR4 and DDR5 memory modules, known as the “Download more RAM” flaw, which allows attackers to bypass advanced Windows security features, including Virtualization-Based Security (VBS) and Hypervisor Code Integrity (HVCI). This vulnerability enables the manipulation of configuration reports from RAM, misleading the system about its actual memory capacity, which can disable antivirus protections and allow the reintroduction of outdated drivers. The exploit can be executed via a single-click script, leading to security failures. Microsoft has released a patch for CVE‑2026‑23670 to enhance memory write protection against such exploits.

North Korea Buried Four-Stage Malware in Flag Images: Zero Antivirus Detections

North Korea's Contagious Interview hackers have been using a deceptive strategy to target developers by posing as recruiters and embedding malware in SVG files. Elastic Security Labs discovered that the attackers hid malicious payloads within HTML comment blocks of these files, allowing the malware to evade antivirus detection. At the time of the findings, no antivirus engines flagged the compromised repositories, which included trojanized GitHub repositories disguised as coding challenges. The malware executed automatically at server startup and deployed four modules: a browser credential and cryptocurrency wallet stealer, a file stealer, a remote access Trojan, and a clipboard monitor. The campaign, tracked as REF9403, is part of the ongoing Contagious Interview operation attributed to North Korea's Lazarus Group, which aims to generate revenue through cryptocurrency theft. Developers are advised to audit any projects run from unsolicited sources and to monitor specific domains associated with the attack.
