Threat actors have been observed distributing malicious payloads such as cryptocurrency miner and clipper malware via SourceForge , a popular software hosting service, under the guise of cracked versions of legitimate applications like Microsoft Office. "One such project, officepackage, on the main website sourceforge.net, appears harmless enough, containing Microsoft Office add-ins copied from a legitimate GitHub project," Kaspersky said in a report published today. "The description and contents of officepackage provided below were also taken from GitHub." While every project created on sourceforge.net gets assigned a "<project>.sourceforge.io" domain name, the Russian cybersecurity company found that the domain for officepackage, "officepackage.sourceforge[.]io," displays a long list of Microsoft Office applications and corresponding links to download them in Russian. On top of that, hovering over the download button reveals a seemi...

Threat hunters have uncovered similarities between a banking malware called Coyote and a newly disclosed malicious program dubbed Maverick that has been propagated via WhatsApp. According to a report from CyberProof, both malware strains are written in .NET, target Brazilian users and banks, and feature identical functionality to decrypt, targeting banking URLs and monitor banking applications. More importantly, both include the ability to spread through WhatsApp Web . Maverick was first documented by Trend Micro early last month, attributing it to a threat actor dubbed Water Saci . The campaign involves two components: A self-propagating malware referred to as SORVEPOTEL that's spread via the desktop web version of WhatsApp and is used to deliver a ZIP archive containing the Maverick payload. The malware is designed to monitor active browser window tabs for URLs that match a hard-coded list of financial institutions in Latin America. Should the URLs match, it establishes con...

Iraqi government networks have emerged as the target of an "elaborate" cyber attack campaign orchestrated by an Iran state-sponsored threat actor called OilRig . The attacks singled out Iraqi organizations such as the Prime Minister's Office and the Ministry of Foreign Affairs, cybersecurity company Check Point said in a new analysis. OilRig, also called APT34, Crambus, Cobalt Gypsy, GreenBug, Hazel Sandstorm (formerly EUROPIUM), and Helix Kitten, is an Iranian cyber group associated with the Iranian Ministry of Intelligence and Security (MOIS). Active since at least 2014, the group has a track record of conducting phishing attacks in the Middle East to deliver a variety of custom backdoors such as Karkoff, Shark, Marlin, Saitama, MrPerfectionManager, PowerExchange, Solar, Mango, and Menorah for information theft. The latest campaign is no exception in that it involves the use of a new set of malware families dubbed Veaty and Spearal, which come with capabilities t...

The Iran-linked  OilRig threat actor  targeted an unnamed Middle East government between February and September 2023 as part of an eight-month-long campaign. The attack led to the theft of files and passwords and, in one instance, resulted in the deployment of a PowerShell backdoor called PowerExchange, the Symantec Threat Hunter Team, part of Broadcom,  said  in a report shared with The Hacker News. The cybersecurity firm is tracking the activity under the name  Crambus , noting that the adversary used the implant to "monitor incoming mails sent from an Exchange Server in  order to execute commands sent by the attackers in the form of emails, and surreptitiously forwarded results to the attackers." Malicious activity is said to have been detected on no less than 12 computers, with backdoors and keyloggers installed on a dozen other machines, indicating a broad compromise of the target. The use of PowerExchange was  first highlighted  by For...

Threat actors have been observed leveraging the deceptive social engineering tactic known as ClickFix to deploy a versatile backdoor codenamed CORNFLAKE.V3. Google-owned Mandiant described the activity, which it tracks as UNC5518, as part of an access-as-a-service scheme that employs fake CAPTCHA pages as lures to trick users into providing initial access to their systems, which is then monetized by other threat groups. "The initial infection vector, dubbed ClickFix, involves luring users on compromised websites to copy a malicious PowerShell script and execute it via the Windows Run dialog box," Google said in a report published today. The access provided by UNC5518 is assessed to be leveraged by at least two different hacking groups, UNC5774 and UNC4108, to initiate a multi-stage infection process and drop additional payloads - UNC5774, another financially motivated group that delivers CORNFLAKE as a way to deploy various subsequent payloads UNC4108, a threat act...

The threat actors behind the zero-day exploitation of a recently-patched security vulnerability in Microsoft Windows have been found to deliver two new backdoors called SilentPrism and DarkWisp . The activity has been attributed to a suspected Russian hacking group called Water Gamayun , which is also known as EncryptHub and LARVA-208. "The threat actor deploys payloads primarily by means of malicious provisioning packages, signed .msi files, and Windows MSC files, using techniques like the IntelliJ runnerw.exe for command execution," Trend Micro researchers Aliakbar Zahravi and Ahmed Mohamed Ibrahim said in a follow-up analysis published last week. Water Gamayun has been linked to the active exploitation of CVE-2025-26633 (aka MSC EvilTwin), a vulnerability in the Microsoft Management Console (MMC) framework, to execute malware by means of a rogue Microsoft Console (.msc) file. The attack chains involve the use of provisioning packages (.ppkg), signed Microsoft Windows...

A China-aligned threat actor codenamed UTA0388 has been attributed to a series of spear-phishing campaigns targeting North America, Asia, and Europe that are designed to deliver a Go-based implant known as GOVERSHELL . "The initially observed campaigns were tailored to the targets, and the messages purported to be sent by senior researchers and analysts from legitimate-sounding, completely fabricated organizations," Volexity said in a Wednesday report. "The goal of these spear phishing campaigns was to socially engineer targets into clicking links that led to a remotely hosted archive containing a malicious payload." Since then, the threat actor behind the attacks is said to have leveraged different lures and fictional identities, spanning several languages, including English, Chinese, Japanese, French, and German. Early iterations of the campaigns have been found to embed links to phishing content either hosted on a cloud-based service or their own infrastruc...

Microsoft is calling attention to an ongoing malvertising campaign that makes use of Node.js to deliver malicious payloads capable of information theft and data exfiltration. The activity, first detected in October 2024, uses lures related to cryptocurrency trading to trick users into installing a rogue installer from fraudulent websites that masquerade as legitimate software like Binance or TradingView. The downloaded installer comes embedded with a dynamic-link library ("CustomActions.dll") that's responsible for harvesting basic system information using Windows Management Instrumentation (WMI) and setting up persistence on the host via a scheduled task. In an attempt to keep up the ruse, the DLL launches a browser window via " msedge_proxy.exe " that displays the legitimate cryptocurrency trading website. It's worth noting that "msedge_proxy.exe" can be used to display any website as a web application. The scheduled task, in the meanwhile...

The threat actor known as Tomiris has been attributed to attacks targeting foreign ministries, intergovernmental organizations, and government entities in Russia with an aim to establish remote access and deploy additional tools. "These attacks highlight a notable shift in Tomiris's tactics, namely the increased use of implants that leverage public services (e.g., Telegram and Discord) as command-and-control (C2) servers," Kaspersky researchers Oleg Kupreev and Artem Ushkov said in an analysis. "This approach likely aims to blend malicious traffic with legitimate service activity to evade detection by security tools." The cybersecurity company said more than 50% of the spear-phishing emails and decoy files used in the campaign used Russian names and contained Russian text, indicating that Russian-speaking users or entities were the primary focus. The spear-phishing emails have also targeted Turkmenistan, Kyrgyzstan, Tajikistan, and Uzbekistan using tailored...

A "potentially destructive actor" aligned with the government of Iran is actively exploiting the well-known  Log4j vulnerability  to infect unpatched VMware Horizon servers with ransomware. Cybersecurity firm SentinelOne dubbed the group " TunnelVision " owing to their heavy reliance on tunneling tools, with overlaps in tactics observed to that of a broader group tracked under the moniker  Phosphorus  as well as Charming Kitten and Nemesis Kitten. "TunnelVision activities are characterized by wide-exploitation of 1-day vulnerabilities in target regions," SentinelOne researchers Amitai Ben Shushan Ehrlich and Yair Rigevsky  said  in a report, with the intrusions detected in the Middle East and the U.S. Also observed alongside Log4Shell is the exploitation of Fortinet FortiOS path traversal flaw ( CVE-2018-13379 ) and the Microsoft Exchange  ProxyShell  vulnerability to gain initial access into the target networks for post-exploitation. "Tunne...

The Russian advanced persistent threat (APT) group known as COLDRIVER has been attributed to a fresh round of ClickFix-style attacks designed to deliver two new "lightweight" malware families tracked as BAITSWITCH and SIMPLEFIX. Zscaler ThreatLabz, which detected the new multi-stage ClickFix campaign earlier this month, described BAITSWITCH as a downloader that ultimately drops SIMPLEFIX, a PowerShell backdoor. COLDRIVER , also tracked as Callisto, Star Blizzard, and UNC4057, is the moniker assigned to a Russia-linked threat actor that's known to target a wide range of sectors since 2019. While early campaign waves were observed using spear-phishing lures to direct targets to credential harvesting pages, the group has been fleshing out its arsenal with custom tools like SPICA and LOSTKEYS , which underscores its technical sophistication. The adversary's use of ClickFix tactics was previously documented by the Google Threat Intelligence Group (GTIG) back in May 2...

A threat actor tracked as Polonium has been linked to over a dozen highly targeted attacks aimed at Israelian entities with seven different custom backdoors since at least September 2021. The intrusions were aimed at organizations in various verticals, such as engineering, information technology, law, communications, branding and marketing, media, insurance, and social services, cybersecurity firm ESET said. Polonium  is the chemical element-themed moniker given by Microsoft to a sophisticated operational group that's believed to be based in Lebanon and is known to exclusively strike Israeli targets. Activities undertaken by the group first came to light earlier this June when the Windows maker disclosed it suspended more than 20 malicious OneDrive accounts created by the adversary for command-and-control (C2) purposes. Core to the attacks has been the use of implants coined CreepyDrive and CreepyBox for their ability to exfiltrate sensitive data to actor-controlled OneDrive ...

Cybersecurity researchers have disclosed a new campaign that potentially targets users in the Middle East through malware that disguises itself as Palo Alto Networks GlobalProtect virtual private network (VPN) tool. "The malware can execute remote PowerShell commands, download and exfiltrate files, encrypt communications, and bypass sandbox solutions, representing a significant threat to targeted organizations," Trend Micro researcher Mohamed Fahmy said in a technical report. The sophisticated malware sample has been observed employing a two-stage process and involves setting up connections to command-and-control (C2) infrastructure that purports to be a company VPN portal, allowing the threat actors to operate freely without tripping any alarms. The initial intrusion vector for the campaign is currently unknown, although it's suspected to involve the use of phishing techniques to deceive users into thinking that they are installing the GlobalProtect agent. The ...

The first quarter of 2025 has been a battlefield in the world of cybersecurity. Cybercriminals continued launching aggressive new campaigns and refining their attack methods. Below is an overview of five notable malware families, accompanied by analyses conducted in controlled environments. NetSupport RAT Exploiting the ClickFix Technique In early 2025, threat actors began exploiting a technique known as ClickFix to distribute the NetSupport Remote Access Trojan (RAT).  This method involves injecting fake CAPTCHA pages into compromised websites, prompting users to execute malicious PowerShell commands that download and run the NetSupport RAT.  Once installed, this RAT grants attackers full control over the victim's system, allowing activities such as real-time screen monitoring, file manipulation, and execution of arbitrary commands. Main technical characteristics of NetSupport RAT Attackers can view and control the victim's screen in real time. Uploads, downloads, m...
