Russian organizations have become the target of a phishing campaign that distributes malware called PureRAT, according to new findings from Kaspersky. "The campaign aimed at Russian business began back in March 2023, but in the first third of 2025 the number of attacks quadrupled compared to the same period in 2024," the cybersecurity vendor said . The attack chains, which have not been attributed to any specific threat actor, commence with a phishing email that contains a RAR file attachment or a link to the archive that masquerades as a Microsoft Word or a PDF document by making use of double extensions ("doc_054_[redacted].pdf.rar"). Present within the archive file is an executable that, when launched, copies itself to the "%AppData%" location of the compromised Windows machine under the name "task.exe" and creates a Visual Basic Script called "Task.vbs" in the Startup VBS folder. The executable then proceeds to unpack another ...

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...

Threat actors have been observed leveraging fake artificial intelligence (AI)-powered tools as a lure to entice users into downloading an information stealer malware dubbed Noodlophile . "Instead of relying on traditional phishing or cracked software sites, they build convincing AI-themed platforms – often advertised via legitimate-looking Facebook groups and viral social media campaigns," Morphisec researcher Shmuel Uzan said in a report published last week. Posts shared on these pages have been found to attract over 62,000 views on a single post, indicating that users looking for AI tools for video and image editing are the target of this campaign. Some of the fake social media pages identified include Luma Dreammachine Al, Luma Dreammachine, and gratistuslibros. Users who land on the social media posts are urged to click on links that advertise AI-powered content creation services, including videos, logos, images, and even websites. One of the bogus websites masquerad...

The Russia-linked threat actor known as COLDRIVER has been observed distributing a new malware called LOSTKEYS as part of an espionage-focused campaign using ClickFix-like social engineering lures. "LOSTKEYS is capable of stealing files from a hard-coded list of extensions and directories, along with sending system information and running processes to the attacker," the Google Threat Intelligence Group (GTIG) said . The malware, the company said, was observed in January, March, and April 2025 in attacks on current and former advisors to Western governments and militaries, as well as journalists, think tanks, and NGOs. In addition, individuals connected to Ukraine have also been singled out. LOSTKEYS is the second custom malware attributed to COLDRIVER after SPICA , marking a continued departure from the credential phishing campaigns the threat actor has been known for. The hacking group is also tracked under the names Callisto, Star Blizzard, and UNC4057. "They ar...

Threat actors with links to the Play ransomware family exploited a recently patched security flaw in Microsoft Windows as a zero-day as part of an attack targeting an unnamed organization in the United States. The attack, per the Symantec Threat Hunter Team, part of Broadcom, leveraged CVE-2025-29824 , a privilege escalation flaw in the Common Log File System (CLFS) driver. It was patched by Microsoft last month. Play , also called Balloonfly and PlayCrypt, is known for its double extortion tactics, wherein sensitive data is exfiltrated prior to encryption in exchange for a ransom. It's active since at least mid-2022. In the activity observed by Symantec, the threat actors are said to have likely leveraged a public-facing Cisco Adaptive Security Appliance (ASA) as an entry point, taking advantage of an as-yet-undetermined method to move to another Windows machine on the target network. The attack is notable for the use of Grixba , a bespoke information stealer previously attr...

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 Russia-linked threat actor known as Gamaredon (aka Shuckworm) has been attributed to a cyber attack targeting a foreign military mission based in Ukraine with an aim to deliver an updated version of a known malware called GammaSteel. The group targeted the military mission of a Western country, per the Symantec Threat Hunter team, with first signs of the malicious activity detected on February 26, 2025. "The initial infection vector used by the attackers appears to have been an infected removable drive," the Broadcom-owned threat intelligence division said in a report shared with The Hacker News. The attack started with the creation of a Windows Registry value under the UserAssist key, followed by launching "mshta.exe" using "explorer.exe" to initiate a multi-stage infection chain and launch two files. The first file, named "NTUSER.DAT.TMContainer00000000000000000001.regtrans-ms," is used to establish communications with a command-and...

A likely lone wolf actor behind the EncryptHub persona was acknowledged by Microsoft for discovering and reporting two security flaws in Windows last month, painting a picture of a "conflicted" individual straddling a legitimate career in cybersecurity and pursuing cybercrime. In a new extensive analysis published by Outpost24 KrakenLabs, the Swedish security company unmasked the up-and-coming cybercriminal, who, about 10 years ago, fled his hometown in Kharkov, Ukraine, to a new place somewhere near the Romanian coast. The vulnerabilities were credited by Microsoft to a party named "SkorikARI with SkorikARI," which has been assessed to be another username used by EncryptHub. The flaws in question, both of which were fixed by Redmond as part of its Patch Tuesday update last month, are below - CVE-2025-24061 (CVSS score: 7.8) - Microsoft Windows Mark-of-the-Web (MotW) Security Feature Bypass Vulnerability CVE-2025-24071 (CVSS score: 6.5) - Microsoft Windo...

The threat actor known as Sticky Werewolf has been linked to targeted attacks primarily in Russia and Belarus with the aim of delivering the Lumma Stealer malware by means of a previously undocumented implant. Cybersecurity company Kaspersky is tracking the activity under the name Angry Likho, which it said bears a "strong resemblance" to Awaken Likho (aka Core Werewolf, GamaCopy, and PseudoGamaredon). "However, Angry Likho's attacks tend to be targeted, with a more compact infrastructure, a limited range of implants, and a focus on employees of large organizations, including government agencies and their contractors," the Russian company said . It's suspected that the threat actors are likely native Russian speakers given the use of fluent Russian in the bait files used to trigger the infection chain. Last month, cybersecurity company F6 (formerly F.A.C.C.T.) described it as a "pro-Ukrainian cyberspy group." The attackers have been found...

Cybersecurity researchers are calling attention to an ongoing campaign that's targeting gamers and cryptocurrency investors under the guise of open-source projects hosted on GitHub . The campaign, which spans hundreds of repositories, has been dubbed GitVenom by Kaspersky. "The infected projects include an automation instrument for interacting with Instagram accounts, a Telegram bot that enables the remote management of Bitcoin wallets and a crack tool to play the Valorant game," the Russian cybersecurity vendor said. "All of this alleged project functionality was fake, and cybercriminals behind the campaign stole personal and banking data and hijacked cryptowallet addresses from the clipboard." The malicious activity has facilitated the theft of 5 bitcoins, approximately worth $456,600 as of writing. It's believed the campaign has been ongoing for at least two years, when some of the fake projects were published. A majority of the infection attempts...

Threat actors have been observed concealing malicious code in images to deliver malware such as VIP Keylogger and 0bj3ctivity Stealer as part of separate campaigns. "In both campaigns, attackers hid malicious code in images they uploaded to archive[.]org, a file-hosting website, and used the same .NET loader to install their final payloads," HP Wolf Security said in its Threat Insights Report for Q3 2024 shared with The Hacker News. The starting point is a phishing email that masquerades as invoices and purchase orders to trick recipients into opening malicious attachments, such as Microsoft Excel documents, that, when opened, exploits a known security flaw in Equation Editor ( CVE-2017-11882 ) to download a VBScript file. The script, for its part, is designed to decode and run a PowerShell script that retrieves an image hosted on archive[.]org and extracts a Base64-encoded code, which is subsequently decoded into a .NET executable and executed. The .NET executable ser...

Cybersecurity researchers have shed light on a previously undocumented aspect associated with ClickFix-style attacks that hinge on taking advantage of a single ad network service as part of a malvertising-driven information stealer campaign dubbed DeceptionAds . "Entirely reliant on a single ad network for propagation, this campaign showcases the core mechanisms of malvertising — delivering over 1 million daily 'ad impressions' [in the last ten days] and causing thousands of daily victims to lose their accounts and money through a network of 3,000+ content sites funneling traffic," Nati Tal, head of Guardio Labs, said in a report shared with The Hacker News. The campaigns, as documented by several cybersecurity companies in recent months, involve directing visitors of pirated movie sites and others to bogus CAPTCHA verification pages that instruct them to copy and execute a Base64-encoded PowerShell command, ultimately leading to the deployment of information st...

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 ...

Users searching for game cheats are being tricked into downloading a Lua-based malware that is capable of establishing persistence on infected systems and delivering additional payloads. "These attacks capitalize on the popularity of Lua gaming engine supplements within the student gamer community," Morphisec researcher Shmuel Uzan said in a new report published today, adding "this malware strain is highly prevalent across North America, South America, Europe, Asia, and even Australia." Details about the campaign were first documented by OALabs in March 2024, in which users were lured into downloading a malware loader written in Lua by exploiting a quirk in GitHub to stage malicious payloads. McAfee Labs, in a subsequent analysis , detailed threat actors' use of the same technique to deliver a variant of the RedLine information stealer by hosting the malware-bearing ZIP archives within legitimate Microsoft repositories. "We disabled user accounts an...
