The Hacker News

The threat actor known as Harvester has been attributed to a new Linux version of its GoGra backdoor deployed as part of attacks likely targeting entities in South Asia. "The malware uses the legitimate Microsoft Graph API and Outlook mailboxes as a covert command-and-control (C2) channel, allowing it to bypass traditional perimeter network defenses," the Symantec and Carbon Black Threat Hunter Ravie Lakshmananhttp://www.blogger.com/profile/[email protected]

Cybersecurity researchers have discovered a previously undocumented data wiper that has been used in attacks targeting Venezuela at the end of last year and the start of 2026. Dubbed Lotus Wiper, the novel file wiper has been used in a destructive campaign targeting the energy and utilities sector in Venezuela, per findings from Kaspersky.

Cybersecurity researchers have discovered a new variant of a known malware called LOTUSLITE that's distributed via a theme related to India's banking sector. "The backdoor communicates with a dynamic DNS-based command-and-control server over HTTPS and supports remote shell access, file operations, and session management, indicating a continued espionage-focused capability set rather than Ravie Lakshmananhttp://www.blogger.com/profile/[email protected]

A critical security vulnerability has been disclosed in a Python-based sandbox called Terrarium that could result in arbitrary code execution. The vulnerability, tracked as CVE-2026-5752, is rated 9.3 on the CVSS scoring system. "Sandbox escape vulnerability in Terrarium allows arbitrary code execution with root privileges on a host process via JavaScript prototype chain traversal," according toRavie Lakshmananhttp://www.blogger.com/profile/[email protected]

Threat actors associated with The Gentlemen ransomware‑as‑a‑service (RaaS) operation have been observed attempting to deploy a known proxy malware called SystemBC. According to new research published by Check Point, the command-and-control (C2 or C&C) server linked to SystemBC has led to the discovery of a botnet of more than 1,570 victims.

Cybersecurity researchers have identified 22 new vulnerabilities in popular models of serial-to-IP converters from Lantronix and Silex that could be exploited to hijack susceptible devices and tamper with data exchanged by them. The vulnerabilities have been collectively codenamed BRIDGE:BREAK by Forescout Research Vedere Labs, which identified nearly 20,000 Serial-to-Ethernet converters exposedRavie Lakshmananhttp://www.blogger.com/profile/[email protected]

A third individual who was employed as a ransomware negotiator has pleaded guilty to conducting ransomware attacks against U.S. companies in 2023. Angelo Martino, 41, of Land O'Lakes, Florida, teamed up with the operators of the BlackCat ransomware starting in April 2023 to assist the e-crime gang in extracting higher amounts as ransoms.

Security teams often present MTTR as an internal KPI. Leadership sees it differently: every hour a threat dwells inside the environment is an hour of potential data exfiltration, service disruption, regulatory exposure, and brand damage.  The root cause of slow MTTR is almost never "not enough analysts." It is almost always the same structural problem: threat intelligence that exists [email protected]

Cybersecurity researchers have discovered a new iteration of an Android malware family called NGate that has been found to abuse a legitimate application called HandyPay instead of NFCGate. "The threat actors took the app, which is used to relay NFC data, and patched it with malicious code that appears to have been AI-generated," ESET security researcher Lukáš Štefanko said in a Ravie Lakshmananhttp://www.blogger.com/profile/[email protected]

The cybersecurity industry has spent the last several years chasing sophisticated threats like zero-days, supply chain compromises, and AI-generated exploits. However, the most reliable entry point for attackers still hasn't changed: stolen credentials. Identity-based attacks remain a dominant initial access vector in breaches today. Attackers obtain valid credentials through credential [email protected]

Cybersecurity researchers have discovered a vulnerability in Google's agentic integrated development environment (IDE), Antigravity, that could be exploited to achieve code execution. The flaw, since patched, combines Antigravity's permitted file-creation capabilities with an insufficient input sanitization in Antigravity's native file-searching tool, find_by_name, to bypass the program's StrictRavie Lakshmananhttp://www.blogger.com/profile/[email protected]

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added eight new vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog, including three flaws impacting Cisco Catalyst SD-WAN Manager, citing evidence of active exploitation.

Monday’s recap shows the same pattern in different places. A third-party tool becomes a way in, then leads to internal access. A trusted download path is briefly swapped to deliver malware. Browser extensions act normally while pulling data and running code. Even update channels are used to push payloads. It’s not breaking systems—it’s bending trust. There’s also a shift in how attacks run. Ravie Lakshmananhttp://www.blogger.com/profile/[email protected]

The fastest way to fall in love with an AI tool is to watch the demo. Everything moves quickly. Prompts land cleanly. The system produces impressive outputs in seconds. It feels like the beginning of a new era for your team. But most AI initiatives don't fail because of bad technology. They stall because what worked in the demo doesn't survive contact with real operations. The gap between a [email protected]

Cybersecurity researchers have discovered a critical "by design" weakness in the Model Context Protocol's (MCP) architecture that could pave the way for remote code execution and have a cascading effect on the artificial intelligence (AI) supply chain.

Web infrastructure provider Vercel has disclosed a security breach that allows bad actors to gain unauthorized access to "certain" internal Vercel systems. The incident stemmed from the compromise of Context.ai, a third-party artificial intelligence (AI) tool, that was used by an employee at the company.
