Attackers used the Ethersphere project's own release automation to publish malicious versions of two of its tools for the Swarm decentralized storage network: bee-js 13.3.0 and Swarm Desktop 0.56.2. Both releases download and run code built to steal the wallet key that Swarm Desktop keeps for its node, along with the stored password that unlocks it. The code is also built to install a backdoor on Windows, macOS, and Linux machines. The bee-js package is the JavaScript library behind Swarm Desktop and the swarm-cli command-line tool. Swarm Desktop runs a Swarm node on a user's own computer and saves the node's private keys there. Both malicious releases have been taken down, and the project's maintainers released a clean Swarm Desktop update today. Neither step removes a backdoor already installed nor protects a key already sent. No theft of funds had been reported at the time of writing. Swarm Desktop 0.56.2 appeared on GitHub at about 00:36 UTC today and was w...

The South Asian cyber espionage group known as Bitter (aka APT-C-08, APT-Q-37, Hazy Tiger, Orange Yali, T-APT-17, and TA397) has been observed targeting South Asian organizations with a previously unreported remote access trojan called PapRAT. "PapRAT has both C++ and Rust implementations," Fortinet FortiGuard Labs researcher Cara Lin said . "Its capabilities include command execution, file uploads and downloads, file deletion, directory and drive enumeration, and screenshot capture. The Rust variant adds PowerShell execution and other commands." The campaign is notable for making use of three different infection chains - A Windows Shortcut (LNK) file that abuses the native "ftp.exe" utility to run scripts and create scheduled tasks designed to maintain contact with a command-and-control (C2) server. A VHDX disk image containing a LNK file that launches a lure Microsoft Excel spreadsheet, while running an MSI installer in the background to d...

A system doesn't always need a complicated bug to let someone in. Sometimes, a blank password is enough. That's one of the bigger stories this week. And it gets worse when the tools meant to keep systems updated or running safely become part of the attack. Elsewhere, attackers are hiding inside normal web traffic, stealing credentials from network devices, and finding new uses for exposed systems. AI is helping some of them move faster, but old mistakes are doing plenty of the work too. Even forgotten settings and small changes made months ago are coming back to cause trouble. There's a lot packed into this week's news, including some strange research findings, fresh attacks, and a few warnings worth taking seriously. Here's the full recap. ⚡ Threat of the Week OpenSSH Flaw Sees Exploitation Attempts — Threat actors are attempting to exploit a recently disclosed security flaw impacting OpenSSH that can enable sign-ins to accounts that have no password set....

A backdoor has been found hiding in the web server that runs Control Web Panel (CWP), a free panel for managing Linux hosting servers, researchers at QiAnXin's XLab said this week. The backdoored web server executes commands that attackers send via web requests, and those requests never appear in its access logs. Installing it takes root access, so the attackers must already control the server. The researchers, who named the backdoor cwpdoor , captured its installer, a shell script posing as a version update, on June 29. The installer handles only two versions of that web server, cwpsrv 1.15.10 and 1.24.0. The researchers do not yet know how attackers get the root access the installer needs. On September 30, an archive holding a copy of the backdoor was uploaded to VirusTotal from Brazil. The researchers say this indicates that "real victims already exist in the wild." They give no count of infected servers. The backdoor is cwpsrv itself, rebuilt with extra code...

How much damage can someone do without breaking much? Quite a lot, it seems. A stolen login can open doors across several systems. A trusted setting can be used to lock people out. Even a simple file copy can reach places it shouldn't. And while new tools are helping find security holes faster, some important systems are still taking months, sometimes over a year, to get patched. Not exactly a great match. The stranger part is how little some attacks now need. Ransom demands without encrypted files. Fake websites that look real enough to steal money. AI tools picking up dangerous instructions while trying to help. Even the attackers are making mistakes in their own code. This week's stories are a reminder that the biggest problems don't always come from clever tricks. Sometimes the easy way works just fine. Here's what else happened. The threats change every week. Subscribe, and we’ll alert you when each new ThreatsDay Bulletin is out.

October 2026 brought another wave of cyber threats targeting US businesses, with attackers exploiting trusted platforms, legitimate authentication processes, and everyday business workflows. For enterprises, these campaigns raise the stakes beyond individual security incidents, increasing the risk of financial losses, data breaches, and costly operational disruption. Below, we examine five active cyber threats through real-world sandbox investigations, revealing how they operate, the risks they pose to organizations, and how security teams can detect and contain attacks faster to minimize business impact. 1. SkyW4lker: Microsoft 365 Phishing Puts US Corporate Accounts at Risk SkyW4lker is an active phishing kit that exploits Microsoft's legitimate device-code authentication to compromise corporate accounts without stealing passwords or bypassing MFA. ANY.RUN researchers identified 618 related sandbox analyses between June and October 21, 2026, with 46% coming from the US. ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added a medium-severity security flaw impacting multiple Apple operating systems to its Known Exploited Vulnerabilities ( KEV ) catalog, following reports of active exploitation. The vulnerability in question is CVE-2024-27834 (CVSS score: 5.5), a case of improper authentication that could allow an attacker with arbitrary read and write capability to bypass Pointer Authentication. It was addressed by Apple in May 2024 with improved checks in iOS 16.7.8 and iPadOS 16.7.8, iOS 17.5 and iPadOS 17.5, macOS Sonoma 14.5, tvOS 17.5, watchOS 10.5, and Safari 17.5. The vulnerability was demonstrated as a zero-day at the Pwn2Own Vancouver hacking contest held in March that year. The addition of CVE-2024-27834 to the KEV catalog follows a report from Sekoia that threat actors possibly linked to Russia exploited previously patched vulnerabilities in Safari and Google Chrome to deliver malware capable of harves...

The Russia-linked threat actor known as APT29 is presumed to be behind a large-scale watering hole campaign targeting iOS and Android users through compromised websites, fake domains, and a supply chain attack involving a Ukrainian web analytics service called Plerdy SEO Tracker. "The injected JavaScript code collects browser and device attributes," Sekoia researchers Amaury-Jacques Garçon and Félix Aime said in a technical report shared with The Hacker News. "Then, the delivery infrastructure delivers a platform-specific N-day exploit chain targeting either iOS or Android." The end goal of the attacks is to serve payloads capable of stealing browser cookies, and in some cases, Wi-Fi passwords or full mobile device data. The activity, codenamed Poisoned Source , was discovered by the French cybersecurity company in mid-October 2026. A defining aspect of the campaign is the use of three infection vectors - Compromise of legitimate websites to inject mal...

A China-aligned threat actor known as SlippyNunchucks has been attributed to a Domain Name System (DNS) hijacking operation abusing insecure HTTP communications in Windows versions of Sogou Input Method as part of a surveillance campaign designed to deploy an implant called DarkVigil (aka FDMTP). The campaign, observed starting July 1, 2026, is assessed to have targeted organizations and Chinese-speaking individuals in Hong Kong, Thailand, Japan, Vietnam, Oman, and Sri Lanka, according to ESET. "DarkVigil implants are typically deployed through popular Chinese applications," ESET researcher Anh Ho said in a report shared with The Hacker News. "By abusing these applications, the SlippyNunchucks threat actor has been able to reach Chinese-speaking users across Asia and Europe." Some of the applications abused by the adversary include Sogou Input Method, QuickFox, QingTalk, MiYunChat, SoftCam, and tawk.to. Active since at least September 15, 2023, SlippyNunc...

Russian authorities have arrested three suspected members of a threat group known as VasyGrek and dismantled its criminal infrastructure. Also known as Fluffy Wolf, the threat actor has a history of targeting Russian and international companies since 2016. The Ministry of Internal Affairs of the Russian Federation (MVD) said members of the group are "suspected of embezzling funds from the accounts of organizations, as well as creating, distributing, and using malicious software." In one September 2025 case highlighted by the ministry, the attackers are said to have sent a phishing email to an unnamed organization, masquerading it as business correspondence and instructing recipients to open a reconciliation report that triggered the execution of malware. The incident resulted in losses of 660,000 rubles ($8,000) from the organization's bank account, with the attackers transferring the funds to accounts under their control. "The attacks utilized a vast ...

Binance on Tuesday said the record-setting theft of $6.43 billion in assets from the world's largest cryptocurrency exchange was the culmination of a "sophisticated, multi-stage campaign" that involved the use of a tampered Homebrew installation and recruitment-themed social engineering attack targeting two of its engineers. "It was not a single isolated breach or a simple phishing incident," the company said . "The attackers combined a range of techniques, including social engineering by fake recruitment interviews, malicious software downloads, compromised internal AI tooling, endpoint compromise, and an advanced transaction-authorisation method." The starting point has been traced back to a supply chain attack targeting one of its engineers from the Wallet DevOps team (named "Engineer A"), who downloaded a trojanized Homebrew installer to install a popular artificial intelligence (AI) tool after searching for it on a search engine....

An attacker broke into the update system of the cPGuard security tool on November 2 and used it to send a malicious script to customers' Linux servers. The script installed a backdoor and collected password hashes and other sensitive files from servers that ran it, cPGuard maker OPSSHIELD said in an advisory . In a later disclosure , OPSSHIELD said about 2,950 customer servers ran the script, which sent the files it collected back to the attacker. OPSSHIELD first named cPGuard 5.88.25 as the fix. Its later disclosure says version 5.88.26 removes the backdoor, and a follow-up update removes a scheduled task the script also left. Admins should install the latest version and then check that those files are gone. Credentials the script copied may still work after the update, so any server that may have run the script also needs new passwords and keys. At 02:06 UTC, the attacker, who has not been identified, used compromised credentials to get into cPGuard's update system. ...

A Russia-aligned threat actor known as Gorbag has been observed using simple information stealer malware in attacks targeting Ukrainian organizations. "Active since at least February 2025, the group has focused exclusively on Ukrainian targets, with a clear preference for law enforcement and justice entities, local administrations near the front line, and the defense sector," ESET researcher Damien Schaeffer said in a report shared with The Hacker News. The activity shares overlaps with a cluster tracked by the Computer Emergency Response Team of Ukraine (CERT-UA) under the moniker UAC-0226 and by Trend Micro as SHADOW-EARTH-066 . Gorbag is known to be active since at least February 2025. A key tool in the threat actor's malware arsenal is GIFTEDCROOK, a C/C++ stealer that facilitates the theft of sensitive data from web browsers like Google Chrome, Microsoft Edge, and Mozilla Firefox, such as cookies, browsing history, and authentication data. Earlier this Ju...

A maximum-severity security flaw impacting Siemens SIMATIC IoT2050 Advanced devices has come under active exploitation, VulnCheck has revealed . The vulnerability, tracked as CVE-2026-58115 (CVSS score: 10.0), is a case of missing authentication for a critical function that could be exploited by an unauthenticated remote attacker to run arbitrary code. "SIMATIC IoT2050 Advanced devices running Industrial OS with Node-RED installed contain a missing authentication vulnerability in the Node-RED HTTP interface that could allow an unauthenticated remote attacker to create malicious flows and execute arbitrary code on the underlying server with maximum privileges," Siemens said in an advisory released back in August 2026. The issue has been remediated in versions 4.3.4.1 or later. As mitigations, Siemens recommends that users uninstall Node-RED or harden the installation by following the steps below - Enabling HTTPS access Securing the editor and admin API via cre...

Some attacks this week didn't need much of a trick. A fake support call, a trusted extension, a shared link, or a device with no password. Small things that people barely think about. Yet each was enough to cause serious trouble. Then there were the bigger messes. Billions stolen, hidden networks of hacked devices, poisoned software, and attackers finding new ways to turn normal tools against their users. Even the places meant to keep money and systems safe ended up with problems of their own. The strange part is how often the damage started somewhere nobody was looking. And that's before getting to the long list of fresh bugs, shady services, and scams making the rounds. Quite a bit to sort through. Here's what made the list. ⚡ Threat of the Week N. Korea Sets New Record with Binance $6.43B Crypto Theft — The U.S. Federal Bureau of Investigation (FBI) has officially attributed the theft of more than $6 billion in virtual assets from Binance to a North Korean hack...

A botnet of more than 1.3 million Android devices, mostly TV set-top boxes, lost control of its servers in late October in a takedown led by Google. Google says  it is highly confident that device maker Videostrong intentionally put a backdoor in the boxes and sold access to criminals. They used the boxes for ad fraud and to pass other people's internet traffic through owners' home connections. The backdoor is still on the boxes, and owners cannot remove it themselves. Videostrong, based in Shenzhen, China, makes Android TV boxes and other devices under its own name and for other brands. The backdoor, called x.cpe, was built into many device models and brands over several years. Google does not believe a rogue insider or a mistake was to blame. Google used legal action to take down the domains and servers that controlled the botnet. It also took down the control domains of more than a dozen malware families loaded through the backdoor. Japan's National Police Agenc...

Cybersecurity researchers have disclosed details of a cyber espionage campaign targeting Israel and the Kurdistan Region of Iraq by an Iran state-aligned threat actor between August and October 2026. According to a report published by Dream Research Labs, the campaign has led to the compromise of a high-profile individual in Israel, along with additional compromises affecting a government cloud environment in the Kurdistan Region. The activity has been attributed to a threat actor known as DarkBlinders , an Iran-nexus group assessed to be active since at least September 2024 and linked to attacks aimed at aviation infrastructure and telecommunications in the U.A.E. and Iraq. It exhibits no technical overlap with other known hacking groups. Attacks mounted by the group are known to rely on spear-phishing as an initial access pathway to lure recipients into opening trojanized utilities or clicking on attacker-controlled websites that host similar tools as direct downloads. Prev...

Cybersecurity researchers have disclosed details of a cyber espionage campaign specifically targeting Linux infrastructure associated with government entities and state-affiliated infrastructure. The activity, observed by Palo Alto Networks Unit 42 between October 2025 and April 2026, has been tracked under the moniker CL-UNK-1211 , where "CL" refers to cluster and "UNK" stands for unknown motivation. A notable aspect of the campaign concerns the use of large language models (LLMs) and/or automated artificial intelligence (AI) agents to generate payloads and execute malicious code. "The attackers behind this cluster of activity focused on Linux environments to conduct extensive reconnaissance and maintain persistent network access to support intelligence-gathering," researchers Roey Porat and Tom Fakterman said . "The attackers attempted to dump sensitive databases and exfiltrate government mailboxes to access social media accounts." T...

Cybersecurity researchers have discovered a new Windows infostealer malware called VOLTA-AUTODOXER (aka VOLTA) that makes use of a large language model (LLM) to rank a victim's stolen data by their monetization value. Like other typical stealer families, VOLTA is equipped to harvest passwords and cookies from Chromium-based web browsers; data from Outlook profiles and Slack workspaces; payment cards; cryptocurrency wallet seed phrases; Discord, Telegram, Steam, and Roblox sessions; Microsoft OAuth tokens; SSH and cloud-provider keys; Wi-Fi profiles; and screenshots. "VOLTA builds a structured evidence bundle about the person behind the machine," Cisco Talos researcher Ryan Fetterman said . "This bundle contains geolocation and home address, employer and employer domain, inferred birth year, card last-4 digits, Slack workspaces, document authorship metadata, iPhone backup indicators, and a live Roblox account valuation." To make this information more va...

The U.S. Federal Bureau of Investigation (FBI) has officially attributed the theft of more than $6 billion in virtual assets from Binance to TraderTraitor , a North Korea-aligned elite hacking group also tracked as Jade Sleet, Pressure Chollima, PUKCHONG, Slow Pisces, and UNC4899. The FBI, along with the U.S. Secret Service (USSS) and the Internal Revenue Service Criminal Investigation (IRS-CI), said it observed the threat actor converting stolen assets primarily into Ethereum (ETH). "It is expected these assets will then be further laundered by converting them using DeFi and instant swap services as they prepare them for further laundering stages," the FBI said in a statement. The agency has also provided a list of wallet addresses that the attackers are said to be using to launder the stolen assets. The development comes as Binance said it has resumed phase one of withdrawals starting today between 6 and 9 a.m. UTC after they were paused in the wake of the incide...
