Afghan telecom providers and South Asian critical infrastructure organizations have emerged as the target of a new ongoing campaign that delivers a previously undocumented backdoor called PATCHCORD . According to Acronis Threat Research Unit (TRU) , the backdoor is a compiled C/C++ implant delivered by means of sector-specific lures, including fake VPN installers impersonating Afghan Telecom (AFTEL) and telecom management tools. An analysis of the threat actor's infrastructure has also led to the discovery of another Go-based backdoor dubbed SHEETCORD that uses Google Sheets for command-and-control (C2) communications. The malware has been found to be delivered via a domain impersonating India's National Informatics Center (NIC). "The campaign's infrastructure centers on a single C2 server with multiple associated domains, including domains impersonating Afghan telecom operators and a hijacked legitimate healthcare domain," researchers Darrel Virtusio, San...

Cybersecurity researchers have disclosed details of a new macOS-oriented, Rust-based information stealer called AmnesiaStealer that's capable of hijacking Chromium web browsers to steal session data. The multi-stage stealer is spread via a counterfeit GitHub download page titled "Download for macOS" and claims to be from a verified publisher. The page employs a ClickFix-style lure that instructs users to copy and paste a Base64-encoded command into the macOS Terminal app. The attack chain ultimately leads to the deployment of AmnesiaStealer via a dropper script hosted on a remote server, which, according to Jamf Threat Labs , runs in three distinct stages. "The first is a shell script that downloads and launches the payload," security researcher Thijs Xhaflaire said in a report shared with The Hacker News. "The second is a Rust infostealer that harvests the Keychain, browsers, Apple Notes, and Telegram. The third is a stream_module, fetched on comm...

A previously unseen Android near field communication ( NFC ) relay malware family dubbed WindRelay is being deployed in conjunction with a known remote access trojan (RAT) called SpyNote as part of a contactless payment fraud scheme. The purpose-built malware, according to Group-IB, is designed to capture live card data via NFC and transmit it to fraudsters in real time. It was first detected in the wild in late August 2025. "SpyNote's Accessibility Service access lets the fraudster sideload and activate the NFC app silently, with no screen sharing ever triggered," researchers Alexander Grabko, Konstantinos Angelopoulos, Pavlos Gaitanis, and Bruno Bijelić said .  These attacks typically work by luring prospective targets via phishing, smishing, or vishing scams into sideloading a malicious app. Once installed, the threat actor abuses SpyNote's remote access to install the NFC relay malware without any further user interaction. To lend credibility to the sch...

Companies are used to thinking about attackers as outsiders trying to break in. North Korean IT workers flip that model. They apply for jobs, pass interviews, receive legitimate credentials, and can end up inside the same systems companies spend millions trying to protect. That risk is no longer theoretical. The FBI is now investigating a North Korean remote IT worker who reportedly worked for a U.S. federal agency. For CISOs, the priority is clear: spot the warning signs before a fraudulent hire becomes trusted access. When the Threat Gets Hired A recent joint investigation by Mauro Eldritch ( BCA LTD ), Heiner García ( NorthScan ), and ANY.RUN showed what this looks like from inside the operation. Researchers deliberately hired suspected DPRK developers linked to Lazarus Group and gave them what looked like ordinary virtual desktops. In reality, they were controlled ANY.RUN Sandboxes, capturing their activity in real time. The operation exposed forged identities, re...

Threat actors have begun to exploit a newly disclosed Microsoft SharePoint vulnerability following the release of a proof-of-concept (PoC) code. The vulnerability in question is CVE-2026-55040 (CVSS score: 9.1), which refers to a critical security feature bypass that stems from weak authentication. It was patched by Microsoft as part of its July 2026 Patch Tuesday updates. "The authentication feature could be bypassed as this vulnerability allows impersonation," Microsoft said in an advisory for the flaw last month. "Exploiting this vulnerability could allow an attacker to disclose files and modify data, but the attacker cannot impact the availability of the system." According to Defused Cyber , threat actors are leveraging a PoC exploit released by Rapid7 earlier this week, once again indicating fresh flaws are being rapidly abused in real-world attacks. It's worth mentioning that CVE-2026-55040 is the fifth SharePoint vulnerability to be exploited t...

The North Korean threat actor known as Lazarus Group has been attributed to the zero-day exploitation of a newly patched security flaw impacting Microsoft Windows to deliver a never-before-seen backdoor targeting defense and aerospace companies across France, Germany, Brazil, and India. The activity, per Check Point Research, is part of Operation Dream Job , a long-running cyber espionage and social engineering campaign orchestrated by Pyongyang-backed hackers to target professionals worldwide with fake-but-compelling job offers at firms like Lockheed Martin and Enveil to steal sensitive data and install malware by approaching them on platforms like LinkedIn, pretending to be recruiters in an attempt to build trust. The attacks have been found to exploit CVE-2026-68820 (CVSS score: 7.0), a privilege escalation flaw affecting Windows Ancillary Function Driver for WinSock ("AFD.sys") that was patched by Microsoft as part of its Patch Tuesday updates for August 2026. C...

A massive set of 737 free VPN and proxy extensions have been found to mainly target Russian-speaking users seeking access to blocked services with an aim to intercept browser traffic and route them through a proxy infrastructure. The extensions, published across at least 40 Chrome Web Store developer accounts, racked up 75,486 installs. Of those identified, 274 have been found to impersonate 66 established VPN and privacy brands, including Proton VPN, NordVPN, Surfshark, AdGuard VPN, Browsec, ExpressVPN, CyberGhost, Windscribe, TunnelBear, Cloudflare's 1.1.1.1, and Google's Outline, per Socket. The censorship circumvention extensions "route the user's entire browser session through SOCKS5 proxies operated by a single provider," security researcher Kush Pandya said . "520 of the 522 in the bulk corpus route browser traffic through the same SOCKS5 infrastructure." The vast majority of the extensions have been found to route users' entire browser...

A newly disclosed flaw in the way OpenAI, Anthropic, and Google carried hidden AI reasoning between API calls let researchers recover internal reasoning and secrets from session logs, including API keys and passwords. The weakness affected encrypted reasoning objects used by the providers' reasoning APIs, where a block created in one session could be replayed into another and, during testing, even handed to a weaker model in the same provider family to make it reveal the hidden content. The team behind the paper  Stealing Reasoning Traces from Proprietary LLM APIs  demonstrated four abuse paths: stealing proprietary reasoning for  model distillation , extracting private data from other users' published traces, recovering harmful content concealed behind a safe visible answer, and hiding prompt injections inside opaque reasoning blocks. Across 6,708 public agent trajectories, the team decoded 315,320 thinking blocks. After excluding benchmark sources, it counted 704...

Enterprise defenses are tuned to catch the attacks that make noise. This year's data shows attackers winning by making none. According to Picus Labs' new Blue Report 2026 , which measured more than 338 million real attack simulations across actual client production environments in the first half of 2026, defenses are having one of their strongest years yet. Average prevention effectiveness climbed from 62% to 69% , matching its 2024 peak, and logging reached a four-year high of 58% . The good news: The recovery is real. The bad news: It's taking place almost exclusively at the perimeter. The report's sharper finding is what happens after that perimeter is crossed . Inside, the picture inverts : defenses that look strong from the outside turn soft , and are the softest of all against the quiet moves, the reconnaissance and credential theft that precede every serious breach.  This is a fault line that runs through the entire report. A vulnerable interior behin...
