Acronis uncovered PATCHCORD, a stealthy backdoor targeting Afghan telecom and South Asian infrastructure via fake VPN tools and Google Sheets C2. Researchers at Acronis just documented an espionage operation that reads like it was built by someone with genuinely good taste in disguises. Their Threat Research Unit report tracks a previously undocumented backdoor called PATCHCORD, […]
Attackers are buying expired domains to exploit their reputation, traffic and DNS history, using them for malware delivery, scams and C2 infrastructure. Every day, roughly 65,000 domain names that once belonged to someone else get re-registered by a new owner. Infoblox Threat Intel calls these dropcatch domains, and in the first half of 2026 they […]
A new Mirai-based modular Linux botnet malware called Evooo1Bot has been targeting internet-facing gateway devices, turning them into SOCKS5 traffic relay nodes. [...]
Threat actors are acquiring expired domains to inherit website traffic and reputation to redirect victims to scams and malware on a large scale. DNS threat intelligence firm Infoblox has given the name dropcatch domains to those that get a second chance, where an expired domain becomes available for registration and is then snapped up by another party. During the first half of 2026, 50,400
The threat actor known as HoneyMyte (aka Mustang Panda) has been observed deploying an updated version of the CoolClient backdoor with a signed Windows kernel-mode rootkit that can hide and protect malicious processes, files, registry objects, and command-and-control (C2) network information. Russian cybersecurity vendor Kaspersky said it identified victims in Myanmar, Mongolia, Pakistan,
Some weeks have one big security story. Others bring many smaller updates that are easy to miss but still matter. This week has plenty of them, covering cloud services, AI tools, malware, data breaches, scams, and new attack methods. The latest ThreatsDay Bulletin puts all of these short updates in one place, so you can quickly catch up on what happened, what changed, and what security teams
Beyond Mirai’s usual functions, the new code features include encrypted communications with command-and-control servers and a “sniffer” that looks for default access credentials.
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 (
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
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
In the past few weeks, I have been using Gemma4 as a Large Language Model (LLM) to see how useful it can be to analyze some of the malware hashes uploaded to the DShield sensor over the past 30 days and figure out how its recommendation can be considered useful about the activity my DShield sensor is collecting and tracking. The model I use for this testing is gemma4:e4b [2] using two sites to compare the data against VirusTotal and CyberGordon. 
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
A new NFC relay malware designated as WindRelay, paired with SpyNote RAT enables live-call fraud, combining social engineering with dual digital and physical cash-out.
Cybersecurity researchers have discovered a new version of the Kimwolf/AISURU Android and Internet of Things (IoT) botnet that comes with significant improvements to improve its operational resilience and conduct distributed denial-of-service (DDoS) attacks. The new version, tracked as Kimwolf v7, was discovered by Palo Alto Networks Unit 42 in February 2026. "Kimwolf v7 adds an HTTP/2-based
The Computer Emergency Response Team of Ukraine (CERT-UA) has disclosed details of a new social engineering campaign orchestrated by Russian nation-state threat actors targeting IT workers in the country by masquerading as recruiters to trick them into installing malware. CERT-UA pinned the activity on a threat cluster it tracks as UAC-0145, which is a subgroup within Sandworm (aka APT44,

A lot of security problems still begin with someone doing a completely normal thing. Cloning a repo. Answering a call. Leaving a box exposed. Trusting the default. That pretty much covers the mood this week. Old bugs are back, supply chains are getting stranger, and some exploit paths are so short you wonder what was supposed to stop them in the first place. That’s only part of it. Here’s
North Korea's state hackers are no longer content to type prompts into public chatbots. One of the country's main espionage groups has begun running artificial intelligence (AI) offline on its own servers, connecting document-search tools to files in its possession, and collecting the software parts needed to build AI into its malware. South Korean security firm Genians says it uncovered the
Go inside Huntress and the FBI’s five-year pursuit of Silk Typhoon, from 88,000 Exchange backdoors to an arrest and a wider fight against cybercrime.
Three separate research efforts last week demonstrated ways to defeat passkey protections without breaking the cryptography they rest on. Passkeys are designed to replace reusable passwords and resist phishing. The attacks instead reused signed authentication material that Windows had exposed, abused a cloud-synced passkey system from malware already on the victim's machine, and used a
Cybersecurity researchers have flagged a malicious Microsoft Visual Studio Code (VS Code) extension named Solidity Pro ("solidity-pro") that has been observed delivering a browser wallet and credential stealer. The names of the extensions are below - helper-beeps.solidity-pro web3devtoolsx.solidity-pro Although neither of the extensions is now available on Open VSX, the GitHub repository
A cluster of nearly 800 malicious packages has been published to the npm registry as part of a new campaign designed to deliver cross-platform malware targeting Windows, Mac, and Linux systems. "These packages appear to use AI slop squatted, or randomly generated typo-squatting package names, but all of them deliver a powerful RAT and infostealer payload," OpenSourceMalware researcher Paul
ClickFix-style attacks are being used to deliver a Go-based malware capable of stealing cryptocurrency assets, as well as browser-stored passwords, Apple iCloud Keychain data, and cached credentials. The macOS-focused infection chain is designed to deliver a shell script that profiles the host and then fetches a macOS malware payload that's compatible with the computer's CPU architecture. "
Entra ID researcher Dirk-jan Mollema demonstrated that malware already running in a signed-in Windows session can silently use the victim's Windows Hello for Business key to authenticate to Microsoft Entra ID. The attacker can then establish longer-term cloud access, register a device it controls, obtain a Primary Refresh Token (PRT), and add further authentication methods where tenant policies
