The Pakistan-aligned threat group tracked as Transparent Tribe (aka APT36 and Earth Karkaddan) has been attributed to a fresh set of cyber attacks targeting government and defense entities in India and Afghanistan. The attacks, per Zscaler ThreatLabz, involve the use of previously undocumented tools called RUSTYSHADE, RUSTYMOVE, PSNATCH, and BASHNATCH. The activity has been codenamed Operation RapidRust . "APT36 has maintained a high operational tempo and updated their tactics, techniques, and procedures (TTPs) in continued attacks targeting government and defense organizations in India and Afghanistan," Sudeep Singh , senior manager of APT Research at Zscaler ThreatLabz, said in a technical report published this week. The discovery comes a little over a month after  Acronis Threat Research Unit (TRU) tied the long-running persistent threat group to another campaign aimed at Afghan telecom providers and South Asian critical infrastructure organizations using a backdo...

Microsoft has released fixes for a maximum-severity security flaw in Azure AI Foundry that could be exploited to achieve privilege escalation. No customer action is required. The vulnerability, tracked as CVE-2026-85889 , carries a CVSS score of 10.0. "Missing authentication for critical function in Azure AI Foundry allows an unauthorized attacker to elevate privileges over a network," Microsoft said in a Thursday advisory. Azure AI Foundry, also called Microsoft Foundry, is an enterprise platform designed to build, deploy, and manage generative artificial intelligence (AI) applications and agents. The Windows maker credited security researcher Rémy Marot (@R_Marot) for discovering and reporting the flaw. There is no evidence that the issue has been exploited in the wild. Also patched by Microsoft in recent days are a number of other critical flaws -

The Iran-linked "hacktivist" persona known as Handala Hack has been attributed to a Telegram-based surveillance backdoor called HEAVYGRAM and a Delphi-based utility known as CRUDEEXCLUDE . "HEAVYGRAM offers builtin commands supporting remote command execution, system, network and process information discovery, data and Telegram session files exfiltration, screenshot capture, DLL sideloading, file cleanup, and persistence via Windows autorun registry keys," Group-IB said . On the other hand, CRUDEEXCLUDE is a Delphi-based Windows utility employed to prepare environments for the deployment of subsequent stages such as HEAVYGRAM. First observed in late July 2024, the malware is often disguised as a legitimate application with a graphical user interface (GUI), and configures Microsoft Defender exclusion paths for defense evasion. The findings build upon an alert the U.S. Federal Bureau of Investigation (FBI) first issued in March 2026 and again earlier this wee...

The China-aligned state-sponsored threat actor known as FamousSparrow has been observed deploying a previously unreported backdoor called SparroWocky in attacks targeting multiple countries in Latin America since at least August 2025. "SparroWocky is a modular, C++ backdoor," ESET security researchers Alexandre Côté Cyr and Romain Dumont said in a technical report shared with The Hacker News ahead of publication. "Its architecture and the techniques used by its authors indicate strong knowledge of anti-analysis tricks and Windows internals." SparroWocky is so named for the fact that early iterations of the malware have been found to contain the first stanza of Jabberwocky , a famous nonsense poem written by the English author, poet, and mathematician Lewis Carroll in around 1855. The latest findings from ESET indicate that the cyber espionage group , which shares some level of overlap with Earth Estries and Salt Typhoon, has replaced SparrowDoor with Spar...

Cybersecurity agencies in the United States, the United Kingdom, and the Netherlands have detailed a Windows malware that they say Iran's intelligence service uses to spy on dissidents, journalists, and activists around the world. The malware is controlled via the Telegram messaging app and can copy a target's emails and chat messages, take screenshots, and activate the microphone to record audio. The FBI calls it HEAVYGRAM , and the U.K.'s National Cyber Security Center (NCSC) calls it CHOSEN BRICK . The  joint advisory  was published on September 15 by the NCSC , the FBI, and the Netherlands' intelligence service, the AIVD. The FBI also released an  updated analysis  of the malware that expands on a  March 2026 alert , the first to describe the campaign, with more technical detail and new indicators of compromise. The FBI attributes the malware to Iran's Ministry of Intelligence and Security (MOIS), the country's main intelligence agency, and dates th...
