1,500+ Minecraft Players Infected by Java Malware Masquerading as Game Mods on GitHub

1,500+ Minecraft Players Infected by Java Malware Masquerading as Game Mods on GitHub

июн. 18, 2025 Cryptocurrency / Malware
A new multi-stage malware campaign is targeting Minecraft users with a Java-based malware that employs a distribution-as-service (DaaS) offering called Stargazers Ghost Network . "The campaigns resulted in a multi-stage attack chain targeting Minecraft users specifically," Check Point researchers Jaromír Hořejší and Antonis Terefos said in a report shared with The Hacker News. "The malware was impersonating Oringo and Taunahi, which are 'Scripts and macros tools' (aka cheats). Both the first and second stages are developed in Java and can only be executed if the Minecraft runtime is installed on the host machine." The end goal of the attack is to trick players into downloading a Minecraft mod from GitHub and deliver a .NET information stealer with comprehensive data theft capabilities. The campaign was first detected by the cybersecurity company in March 2025. What makes the activity notable is its use of an illicit offering called the Stargazers Ghost...

Water Curse Employs 76 GitHub Accounts to Deliver Multi-Stage Malware Campaign

июн. 18, 2025 Threat Intelligence / Malware
Cybersecurity researchers have exposed a previously unknown threat actor known as Water Curse that relies on weaponized GitHub repositories to deliver multi-stage malware. "The malware enables data exfiltration (including credentials, browser data, and session tokens), remote access, and long-term persistence on infected systems," Trend Micro researchers Jovit Samaniego, Aira Marcelo, Mohamed Fahmy, and Gabriel Nicoleta said in an analysis published this week. The "broad and sustained" campaign, first spotted last month, set up repositories offering seemingly innocuous penetration testing utilities, such as SMTP email bomber and Sakura-RAT, but harbored within their Visual Studio project configuration files malicious payloads that are designed to siphon sensitive data. Water Curse's arsenal incorporates a wide range of tools and programming languages, underscoring their cross-functional development capabilities to target the supply chain with "develope...

Google Chrome Zero-Day CVE-2025-2783 Exploited by TaxOff to Deploy Trinper Backdoor

июн. 17, 2025 Malware / Cyber Espionage
A now-patched security flaw in Google Chrome was exploited as a zero-day by a threat actor known as TaxOff to deploy a backdoor codenamed Trinper . The attack, observed in mid-March 2025 by Positive Technologies, involved the use of a sandbox escape vulnerability tracked as CVE-2025-2783 (CVSS score: 8.3). Google addressed the flaw later that month after Kaspersky reported in-the-wild exploitation in a campaign dubbed Operation ForumTroll targeting various Russian organizations. "The initial attack vector was a phishing email containing a malicious link," security researchers Stanislav Pyzhov and Vladislav Lunin said . "When the victim clicked the link, it triggered a one-click exploit (CVE-2025-2783), leading to the installation of the Trinper backdoor employed by TaxOff." The phishing email is said to have been disguised as an invitation to the Primakov Readings forum – the same lure detailed by Kaspersky – urging users to click on a link that led to a fake...

Discord Invite Link Hijacking Delivers AsyncRAT and Skuld Stealer Targeting Crypto Wallets

Discord Invite Link Hijacking Delivers AsyncRAT and Skuld Stealer Targeting Crypto Wallets

июн. 14, 2025 Malware / Threat Intelligence
A new malware campaign is exploiting a weakness in Discord's invitation system to deliver an information stealer called Skuld and the AsyncRAT remote access trojan. "Attackers hijacked the links through vanity link registration, allowing them to silently redirect users from trusted sources to malicious servers," Check Point said in a technical report. "The attackers combined the ClickFix phishing technique, multi-stage loaders, and time-based evasions to stealthily deliver AsyncRAT, and a customized Skuld Stealer targeting crypto wallets." The issue with Discord's invite mechanism is that it allows attackers to hijack expired or deleted invite links and secretly redirect unsuspecting users to malicious servers under their control. This also means that a Discord invite link that was once trusted and shared on forums or social media platforms could unwittingly lead users to malicious sites. Details of the campaign come a little over a month after the ...

Rare Werewolf APT Uses Legitimate Software in Attacks on Hundreds of Russian Enterprises

июн. 10, 2025 Cryptocurrency / Malware
The threat actor known as Rare Werewolf (formerly Rare Wolf) has been linked to a series of cyber attacks targeting Russia and the Commonwealth of Independent States (CIS) countries. "A distinctive feature of this threat is that the attackers favor using legitimate third-party software over developing their own malicious binaries," Kaspersky said . "The malicious functionality of the campaign described in this article is implemented through command files and PowerShell scripts." The intent of the attacks is to establish remote access to compromised hosts, and siphon credentials, and deploy the XMRig cryptocurrency miner. The activity impacted hundreds of Russian users spanning industrial enterprises and engineering schools, with a smaller number of infections also recorded in Belarus and Kazakhstan. Rare Werewolf , also known by the names Librarian Ghouls and Rezet, is the moniker assigned to an advanced persistent threat (APT) group that has a track record of...

Malicious Browser Extensions Infect Over 700 Users Across Latin America Since Early 2025

июн. 08, 2025 Malware / Browser Security
Cybersecurity researchers have shed light on a new campaign targeting Brazilian users since the start of 2025 to infect users with a malicious extension for Chromium-based web browsers and siphon user authentication data. "Some of the phishing emails were sent from the servers of compromised companies, increasing the chances of a successful attack," Positive Technologies security researcher Klimentiy Galkin said in a report. "The attackers used a malicious extension for Google Chrome, Microsoft Edge, and Brave browsers, as well as Mesh Agent and PDQ Connect Agent." The Russian cybersecurity company, which is tracking the activity under the name Operation Phantom Enigma , said the malicious extension was downloaded 722 times from across Brazil, Colombia, the Czech Republic, Mexico, Russia, and Vietnam, among others. As many as 70 unique victim companies have been identified. Some aspects of the campaign were disclosed in early April by a researcher who goes by th...
Fake Docusign, Gitcode Sites Spread NetSupport RAT via Multi-Stage PowerShell Attack

Fake Docusign, Gitcode Sites Spread NetSupport RAT via Multi-Stage PowerShell Attack

июн. 03, 2025 United States
Threat hunters are alerting to a new campaign that employs deceptive websites to trick unsuspecting users into executing malicious PowerShell scripts on their machines and infect them with the NetSupport RAT malware. The DomainTools Investigations (DTI) team said it identified "malicious multi-stage downloader Powershell scripts" hosted on lure websites that masquerade as Gitcode and Docusign. "These sites attempt to deceive users into copying and running an initial PowerShell script on their Windows Run command," the company said in a technical report shared with The Hacker News. "Upon doing so, the powershell script downloads another downloader script and executes on the system, which in turn retrieves additional payloads and executes them eventually installing NetSupport RAT on the infected machines." It's believed that these counterfeit sites may be propagated via social engineering attempts over email and/or social media platforms. The Po...
New EDDIESTEALER Malware Bypasses Chrome's App-Bound Encryption to Steal Browser Data

New EDDIESTEALER Malware Bypasses Chrome's App-Bound Encryption to Steal Browser Data

мая 30, 2025 Browser Security / Malware
A new malware campaign is distributing a novel Rust-based information stealer dubbed EDDIESTEALER using the popular ClickFix social engineering tactic initiated via fake CAPTCHA verification pages. "This campaign leverages deceptive CAPTCHA verification pages that trick users into executing a malicious PowerShell script, which ultimately deploys the infostealer, harvesting sensitive data such as credentials, browser information, and cryptocurrency wallet details," Elastic Security Labs researcher Jia Yu Chan said in an analysis. The attack chains begin with threat actors compromising legitimate websites with malicious JavaScript payloads that serve bogus CAPTCHA check pages, which prompt site visitors to "prove you are not [a] robot" by following a three-step process, a prevalent tactic called ClickFix . This involves instructing the potential victim to open the Windows Run dialog prompt, paste an already copied command into the "verification window"...
New Windows RAT Evades Detection for Weeks Using Corrupted DOS and PE Headers

New Windows RAT Evades Detection for Weeks Using Corrupted DOS and PE Headers

мая 29, 2025 Malware / Windows Security
Cybersecurity researchers have taken the wraps off an unusual cyber attack that leveraged malware with corrupted DOS and PE headers, according to new findings from Fortinet. The DOS (Disk Operating System) and PE (Portable Executable) headers are essential parts of a Windows PE file , providing information about the executable. While the DOS header makes the executable file backward compatible with MS-DOS and allows it to be recognized as a valid executable by the operating system, the PE header contains the metadata and information necessary for Windows to load and execute the program. "We discovered malware that had been running on a compromised machine for several weeks," researchers Xiaopeng Zhang and John Simmons from the FortiGuard Incident Response Team said in a report shared with The Hacker News. "The threat actor had executed a batch of scripts and PowerShell to run the malware in a Windows process." Fortinet said while it was unable to extract th...
Hackers Use TikTok Videos to Distribute Vidar and StealC Malware via ClickFix Technique

Hackers Use TikTok Videos to Distribute Vidar and StealC Malware via ClickFix Technique

мая 23, 2025 Cryptocurrency / Malware
The malware known as Latrodectus has become the latest to embrace the widely-used social engineering technique called ClickFix as a distribution vector. "The ClickFix technique is particularly risky because it allows the malware to execute in memory rather than being written to disk," Expel said in a report shared with The Hacker News. "This removes many opportunities for browsers or security tools to detect or block the malware." Latrodectus, believed to be a successor to IcedID, is the name given to a malware that acts as a downloader for other payloads, such as ransomware. It was first documented by Proofpoint and Team Cymru in April 2024.
Fileless Remcos RAT Delivered via LNK Files and MSHTA in PowerShell-Based Attacks

Fileless Remcos RAT Delivered via LNK Files and MSHTA in PowerShell-Based Attacks

мая 16, 2025 Malware / Cyber Attack
Cybersecurity researchers have shed light on a new malware campaign that makes use of a PowerShell-based shellcode loader to deploy a remote access trojan called Remcos RAT. "Threat actors delivered malicious LNK files embedded within ZIP archives, often disguised as Office documents," Qualys security researcher Akshay Thorve said in a technical report. "The attack chain leverages mshta.exe for proxy execution during the initial stage." The latest wave of attacks, as detailed by Qualys, employs tax-related lures to entice users into opening a malicious ZIP archive containing a Windows shortcut (LNK) file, which, in turn, makes use of mshta.exe, a legitimate Microsoft tool used to run HTML Applications (HTA). The binary is used to execute an obfuscated HTA file named "xlab22.hta" hosted on a remote server, which incorporates Visual Basic Script code to download a PowerShell script, a decoy PDF, and another HTA file similar to xlab22.hta called "3...
