Threat actors are leveraging fake Google Meet web pages as part of an ongoing malware campaign dubbed ClickFix to deliver infostealers targeting Windows and macOS systems. "This tactic involves displaying fake error messages in web browsers to deceive users into copying and executing a given malicious PowerShell code, finally infecting their systems," French cybersecurity company Sekoia said in a report shared with The Hacker News. Variations of the ClickFix (aka ClearFake and OneDrive Pastejacking) campaign have been reported widely in recent months , with threat actors employing different lures to redirect users to bogus pages that aim to deploy malware by urging site visitors to run an encoded PowerShell code to address a supposed issue with displaying content in the web browser. These pages are known to masquerade as popular online services, including Facebook, Google Chrome, PDFSimpli, and reCAPTCHA, and now Google Meet as well as potentially Zoom - meet.googl

The Russian threat actor known as RomCom has been linked to a new wave of cyber attacks aimed at Ukrainian government agencies and unknown Polish entities since at least late 2023. The intrusions are characterized by the use of a variant of the RomCom RAT dubbed SingleCamper (aka SnipBot or RomCom 5.0), said Cisco Talos, which is monitoring the activity cluster under the moniker UAT-5647. "This version is loaded directly from the registry into memory and uses a loopback address to communicate with its loader," security researchers Dmytro Korzhevin, Asheer Malhotra, Vanja Svajcer, and Vitor Ventura noted . RomCom, also tracked as Storm-0978, Tropical Scorpius, UAC-0180, UNC2596, and Void Rabisu, has engaged in multi-motivational operations such as ransomware, extortion, and targeted credential gathering since its emergence in 2022. It's been assessed that the operational tempo of their attacks has increased in recent months with an aim to set up long-term persisten

An advanced persistent threat (APT) actor with suspected ties to India has sprung forth with a flurry of attacks against high-profile entities and strategic infrastructures in the Middle East and Africa. The activity has been attributed to a group tracked as SideWinder , which is also known as APT-C-17, Baby Elephant, Hardcore Nationalist, Leafperforator, Rattlesnake, Razor Tiger, and T-APT-04. "The group may be perceived as a low-skilled actor due to the use of public exploits, malicious LNK files and scripts as infection vectors, and the use of public RATs, but their true capabilities only become apparent when you carefully examine the details of their operations," Kaspersky researchers Giampaolo Dedola and Vasily Berdnikov said . Targets of the attacks include government and military entities, logistics, infrastructure and telecommunications companies, financial institutions, universities, and oil trading companies located in Bangladesh, Djibouti, Jordan, Malaysia, the

Threat actors are attempting to abuse the open-source EDRSilencer tool as part of efforts to tamper endpoint detection and response (EDR) solutions and hide malicious activity. Trend Micro said it detected "threat actors attempting to integrate EDRSilencer in their attacks, repurposing it as a means of evading detection." EDRSilencer , inspired by the NightHawk FireBlock tool from MDSec, is designed to block outbound traffic of running EDR processes using the Windows Filtering Platform ( WFP ). It supports terminating various processes related to EDR products from Microsoft, Elastic, Trellix, Qualys, SentinelOne, Cybereason, Broadcom Carbon Black, Tanium, Palo Alto Networks, Fortinet, Cisco, ESET, HarfangLab, and Trend Micro. By incorporating such legitimate red teaming tools into their arsenal, the goal is to render EDR software ineffective and make it a lot more challenging to identify and remove malware. "The WFP is a powerful framework built into Windows for

The North Korean threat actor known as ScarCruft has been linked to the zero-day exploitation of a now-patched security flaw in Windows to infect devices with malware known as RokRAT . The vulnerability in question is CVE-2024-38178 (CVSS score: 7.5), a memory corruption bug in the Scripting Engine that could result in remote code execution when using the Edge browser in Internet Explorer Mode. It was patched by Microsoft as part of its Patch Tuesday updates for August 2024. However, successful exploitation requires an attacker to convince a user to click on a specially crafted URL in order to initiate the execution of malicious code. The AhnLab Security Intelligence Center (ASEC) and the National Cyber Security Center (NCSC) of the Republic of Korea, which were credited with discovering and reporting the shortcoming, have assigned the activity cluster the name Operation Code on Toast. The organizations are tracking ScarCruft under the moniker TA-RedAnt, which was previously

A new spear-phishing campaign targeting Brazil has been found delivering a banking malware called Astaroth (aka Guildma) by making use of obfuscated JavaScript to slip past security guardrails. "The spear-phishing campaign's impact has targeted various industries, with manufacturing companies, retail firms, and government agencies being the most affected," Trend Micro said in a new analysis. "The malicious emails often impersonate official tax documents, using the urgency of personal income tax filings to trick users into downloading the malware." The cybersecurity company is tracking the threat activity cluster under the name Water Makara. It's worth pointing out that Google's Threat Analysis Group (TAG) has assigned the moniker PINEAPPLE to a similar intrusion set that delivers the same malware to Brazilian users. Both these campaigns share a point of commonality in that they commence with phishing messages that impersonate official entities su

New variants of an Android banking trojan called TrickMo have been found to harbor previously undocumented features to steal a device's unlock pattern or PIN. "This new addition enables the threat actor to operate on the device even while it is locked," Zimperium security researcher Aazim Yaswant said in an analysis published last week. First spotted in the wild in 2019, TrickMo is so named for its associations with the TrickBot cybercrime group and is capable of granting remote control over infected devices, as well as stealing SMS-based one-time passwords (OTPs) and displaying overlay screens to capture credentials by abusing Android's accessibility services. Last month, Italian cybersecurity company Cleafy disclosed updated versions of the mobile malware with improved mechanisms to evade analysis and grant itself additional permissions to perform various malicious actions on the device, including carrying out unauthorized transactions. Some of the new varia

Cybersecurity researchers have disclosed a new malware campaign that leverages a malware loader named PureCrypter to deliver a commodity remote access trojan (RAT) called DarkVision RAT. The activity, observed by Zscaler ThreatLabz in July 2024, involves a multi-stage process to deliver the RAT payload. "DarkVision RAT communicates with its command-and-control (C2) server using a custom network protocol via sockets," security researcher Muhammed Irfan V A said in an analysis. "DarkVision RAT supports a wide range of commands and plugins that enable additional capabilities such as keylogging, remote access, password theft, audio recording, and screen captures." PureCrypter, first publicly disclosed in 2022, is an off-the-shelf malware loader that's available for sale on a subscription basis, offering customers the ability to distribute information stealers, RATs, and ransomware. The exact initial access vector used to deliver PureCrypter and, by extensio

North Korean threat actors have been observed using a Linux variant of a known malware family called FASTCash to steal funds as part of a financially-motivated campaign. The malware is "installed on payment switches within compromised networks that handle card transactions for the means of facilitating the unauthorized withdrawal of cash from ATMs," a security researcher who goes by HaxRob said . FASTCash was first documented by the U.S. government in October 2018 as used by adversaries linked to North Korea in connection with an ATM cashout scheme targeting banks in Africa and Asia since at least late 2016. "FASTCash schemes remotely compromise payment switch application servers within banks to facilitate fraudulent transactions," the agencies noted at the time. "In one incident in 2017, HIDDEN COBRA actors enabled cash to be simultaneously withdrawn from ATMs located in over 30 different countries. In another incident in 2018, HIDDEN COBRA actors enab

Cybersecurity researchers have disclosed a new malware campaign that delivers Hijack Loader artifacts that are signed with legitimate code-signing certificates. French cybersecurity company HarfangLab, which detected the activity at the start of the month, said the attack chains aim to deploy an information stealer known as Lumma. Hijack Loader , also known as DOILoader, IDAT Loader, and SHADOWLADDER, first came to light in September 2023. Attack chains involving the malware loader typically involve tricking users into downloading a booby-trapped binary under the guise of pirated software or movies. Recent variations of these campaigns have been found to direct users to fake CAPTCHA pages that urge site visitors to prove they are human by copying and running an encoded PowerShell command that drops the malicious payload in the form of a ZIP archive. HarfangLab said it observed three different versions of the PowerShell script starting mid-September 2024 - A PowerShell script

Cybersecurity researchers have found that entry points could be abused across multiple programming ecosystems like PyPI, npm, Ruby Gems, NuGet, Dart Pub, and Rust Crates to stage software supply chain attacks. "Attackers can leverage these entry points to execute malicious code when specific commands are run, posing a widespread risk in the open-source landscape," Checkmarx researchers Yehuda Gelb and Elad Rapaport said in a report shared with The Hacker News. The software supply chain security company noted that entry-point attacks offer threat actors a more sneaky and persistent method of compromising systems in a manner that can bypass traditional security defenses. Entry points in a programming language like Python refer to a packaging mechanism that allows developers to expose certain functionality as a command-line wrapper (aka console_scripts). Alternatively, they can also serve to load plugins that augment a package's features. Checkmarx noted that while en

A new tax-themed malware campaign targeting insurance and finance sectors has been observed leveraging GitHub links in phishing email messages as a way to bypass security measures and deliver Remcos RAT, indicating that the method is gaining traction among threat actors. "In this campaign, legitimate repositories such as the open-source tax filing software, UsTaxes, HMRC, and InlandRevenue were used instead of unknown, low-star repositories," Cofense researcher Jacob Malimban said . "Using trusted repositories to deliver malware is relatively new compared to threat actors creating their own malicious GitHub repositories. These malicious GitHub links can be associated with any repository that allows comments." Central to the attack chain is the abuse of GitHub infrastructure for staging the malicious payloads. One variation of the technique, first disclosed by OALABS Research in March 2024, involves threat actors opening a GitHub issue on well-known repositories

OpenAI on Wednesday said it has disrupted more than 20 operations and deceptive networks across the world that attempted to use its platform for malicious purposes since the start of the year. This activity encompassed debugging malware, writing articles for websites, generating biographies for social media accounts, and creating AI-generated profile pictures for fake accounts on X. "Threat actors continue to evolve and experiment with our models, but we have not seen evidence of this leading to meaningful breakthroughs in their ability to create substantially new malware or build viral audiences," the artificial intelligence (AI) company said . It also said it disrupted activity that generated social media content related to elections in the U.S., Rwanda, and to a lesser extent India and the European Union, and that none of these networks attracted viral engagement or sustained audiences. This included efforts undertaken by an Israeli commercial company named STOIC (als

Cybersecurity researchers have shed light on a new digital skimmer campaign that leverages Unicode obfuscation techniques to conceal a skimmer dubbed Mongolian Skimmer. "At first glance, the thing that stood out was the script's obfuscation, which seemed a bit bizarre because of all the accented characters," Jscrambler researchers said in an analysis. "The heavy use of Unicode characters, many of them invisible, does make the code very hard to read for humans." The script, at its core, has been found to leverage JavaScript's capability to use any Unicode character in identifiers to hide the malicious functionality. The end goal of the malware is to steal sensitive data entered on e-commerce checkout or admin pages, including financial information, which are then exfiltrated to an attacker-controlled server. The skimmer, which typically manifests in the form of an inline script on compromised sites that fetches the actual payload from an external serv
