Nothing here looks dramatic at first glance. That’s the point. Many of this week’s threats begin with something ordinary, like an ad, a meeting invite, or a software update. Behind the scenes, the tactics are sharper. Access happens faster. Control is established sooner. Cleanup becomes harder. Here is a quick look at the signals worth paying attention to. AI-powered command execution Kali Linux Integrates Claude AI Assistant via MCP Kali Linux, an advanced penetration testing Linux distribution used for ethical hacking and network security assessments, has added an integration with Anthropic's Claude large language model through the Model Context Protocol (MCP) to issue commands in natural language and translate them into technical commands. Belarus-linked Android spyware ResidentBat Infrastructure Analyzed ResidentBat is an Android spyware implant used by Belarusian autho...

Introduction: Steal It Today, Break It in a Decade Digital evolution is unstoppable, and though the pace may vary, things tend to fall into place sooner rather than later. That, of course, applies to adversaries as well. The rise of ransomware and cyber extortion generated funding for a complex and highly professional criminal ecosystem. The era of the cloud brought general availability of almost infinite amounts of storage. So there is literally nothing that stops criminals from stealing and trafficking heaps of data, be it encrypted or not.  Patient adversaries are employing a "Harvest Now, Decrypt Later" (HNDL) strategy. They are quietly accumulating encrypted data with the intention of decrypting it later using quantum computers. Any data requiring long-term security, such as trade secrets or classified designs, is vulnerable because its lifespan will inevitably outlive its current encryption. Therefore, it is crucial that organizations begin planning their PQC migrati...

A "coordinated developer-targeting campaign" is using malicious repositories disguised as legitimate Next.js projects and technical assessments to trick victims into executing them and establish persistent access to compromised machines. "The activity aligns with a broader cluster of threats that use job-themed lures to blend into routine developer workflows and increase the likelihood of code execution," the Microsoft Defender Security Research Team said in a report published this week. The tech giant said the campaign is characterized by the use of multiple entry points that lead to the same outcome, where attacker-controlled JavaScript is retrieved at runtime and executed to facilitate command-and-control (C2). The attacks rely on the threat actors setting up fake repositories on trusted developer platforms like Bitbucket, using names like "Cryptan-Platform-MVP1" to trick developers looking for jobs into running them as part of an assessment proces...

Cybersecurity researchers have disclosed details of a new malicious package discovered on the NuGet Gallery, impersonating a library from financial services firm Stripe in an attempt to target the financial sector. The package, codenamed StripeApi.Net, attempts to masquerade as Stripe.net , a legitimate library from Stripe that has over 75 million downloads. It was uploaded by a user named StripePayments on February 16, 2026. The package is no longer available. "The NuGet page for the malicious package is set up to resemble the official Stripe.net package as closely as possible," ReversingLabs Petar Kirhmajer said . "It uses the same icon as the legitimate package and contains a nearly identical readme, only swapping the 'Stripe.net' references to read 'Stripe-net.'" In a further effort to lend credibility to the typosquatted package, the threat actor behind the campaign is said to have artificially inflated the download count to more than 180,00...

A newly disclosed maximum-severity security flaw in Cisco Catalyst SD-WAN Controller (formerly vSmart) and Catalyst SD-WAN Manager (formerly vManage) has come under active exploitation in the wild as part of malicious activity that dates back to 2023. The vulnerability, tracked as CVE-2026-20127 (CVSS score: 10.0), allows an unauthenticated remote attacker to bypass authentication and obtain administrative privileges on an affected system by sending a crafted request. Successful exploitation of the flaw could allow the adversary to obtain elevated privileges and log in to the system as an internal, high-privileged, non-root user account. "This vulnerability exists because the peering authentication mechanism in an affected system is not working properly," Cisco said in an advisory, adding the threat actor could leverage the non-root user account to access NETCONF and manipulate network configuration for the SD-WAN fabric.  The shortcoming affects the following deploym...

Google on Wednesday disclosed that it worked with industry partners to disrupt the infrastructure of a suspected China-nexus cyber espionage group tracked as UNC2814 that breached at least 53 organizations across 42 countries. "This prolific, elusive actor has a long history of targeting international governments and global telecommunications organizations across Africa, Asia, and the Americas," Google Threat Intelligence Group (GTIG) and Mandiant said in a report published today. UNC2814 is also suspected to be linked to additional infections in more than 20 other nations. The tech giant, which has been tracking the threat actor since 2017, has been observed using API calls to communicate with software-as-a-service (SaaS) apps as command-and-control (C2) infrastructure. The idea, it added, is to disguise their malicious traffic as benign. Central to the hacking group's operations is a novel backdoor dubbed GRIDTIDE that abuses Google Sheets API as a communication ...

Cybersecurity researchers have disclosed multiple security vulnerabilities in Anthropic's Claude Code, an artificial intelligence (AI)-powered coding assistant, that could result in remote code execution and theft of API credentials. "The vulnerabilities exploit various configuration mechanisms, including Hooks, Model Context Protocol (MCP) servers, and environment variables – executing arbitrary shell commands and exfiltrating Anthropic API keys when users clone and open untrusted repositories," Check Point researchers Aviv Donenfeld and Oded Vanunu said in a report shared with The Hacker News. The identified shortcomings fall under three broad categories - No CVE (CVSS score: 8.7) - A code injection vulnerability stemming from a user consent bypass when starting Claude Code in a new directory that could result in arbitrary code execution without additional confirmation via untrusted project hooks defined in .claude/settings.json. (Fixed in version 1.0.87 in Sep...

The notorious cybercrime collective known as Scattered LAPSUS$ Hunters (SLH) has been observed offering financial incentives to recruit women to pull off social engineering attacks. The idea is to hire them for voice phishing campaigns targeting IT help desks, Dataminr said in a new threat brief. The group is said to be offering anywhere between $500 and $1,000 upfront per call, in addition to providing them with the necessary pre-written scripts to carry out the attack. "SLH is diversifying its social engineering pool by specifically recruiting women to conduct vishing attacks, likely to increase the success rate of help desk impersonation," the threat intelligence firm said . A high-profile cybercrime supergroup comprising LAPSUS$, Scattered Spider, and ShinyHunters, SLH has a record of engaging in advanced social engineering attacks to sidestep multi-factor authentication (MFA) through techniques like MFA prompt bombing and SIM swapping.  The group's modus ope...
