Horabot Malware Targets 6 Latin American Nations Using Invoice-Themed Phishing Emails

May 14, 2025 Windows Security / Threat Intelligence
Cybersecurity researchers have discovered a new phishing campaign that's being used to distribute malware called Horabot targeting Windows users in Latin American countries like Mexico, Guatemala, Colombia, Peru, Chile, and Argentina. The campaign is "using crafted emails that impersonate invoices or financial documents to trick victims into opening malicious attachments and can steal email credentials, harvest contact lists, and install banking trojans," Fortinet FortiGuard Labs researcher Cara Lin said . The activity, observed by the network security company in April 2025, has primarily singled out Spanish-speaking users. The attacks have also been found to send phishing messages from victims' mailboxes using Outlook COM automation, effectively propagating the malware laterally within corporate or personal networks. In addition, the threat actors behind the campaign execute various VBScript, AutoIt, and PowerShell scripts to conduct system reconnaissance, stea...

May 13, 2025 Cyber Espionage / Malware
The North Korea-linked threat actor known as Konni APT has been attributed to a phishing campaign targeting government entities in Ukraine, indicating the threat actor's targeting beyond Russia . Enterprise security firm Proofpoint said the end goal of the campaign is to collect intelligence on the "trajectory of the Russian invasion." "The group's interest in Ukraine follows historical targeting of government entities in Russia for strategic intelligence gathering purposes," security researchers Greg Lesnewich, Saher Naumaan, and Mark Kelly said in a report shared with The Hacker News. Konni APT , also known as Opal Sleet, Osmium, TA406, and Vedalia , is a cyber espionage group that has a history of targeting entities in South Korea, the United States, and Russia. It's operational since at least 2014. Attack chains mounted by the threat actor often involve the use of phishing emails to distribute malware called Konni RAT (aka UpDog) and redirect r...

MintsLoader Drops GhostWeaver via Phishing, ClickFix — Uses DGA, TLS for Stealth Attacks

May 02, 2025 Malware / Threat Intelligence
The malware loader known as MintsLoader has been used to deliver a PowerShell-based remote access trojan called GhostWeaver. "MintsLoader operates through a multi-stage infection chain involving obfuscated JavaScript and PowerShell scripts," Recorded Future's Insikt Group said in a report shared with The Hacker News. "The malware employs sandbox and virtual machine evasion techniques, a domain generation algorithm (DGA), and HTTP-based command-and-control (C2) communications." Phishing and drive-by download campaigns distributing MintsLoader have been detected in the wild since early 2023, per Orange Cyberdefense . The loader has been observed delivering various follow-on payloads like StealC and a modified version of the Berkeley Open Infrastructure for Network Computing (BOINC) client. The malware has also been put to use by threat actors operating e-crime services like SocGholish (aka FakeUpdates) and LandUpdate808 (aka TAG-124), distributing via p...
Multi-Stage Malware Attack Uses .JSE and PowerShell to Deploy Agent Tesla and XLoader

Multi-Stage Malware Attack Uses .JSE and PowerShell to Deploy Agent Tesla and XLoader

Apr 18, 2025 Malware / Email Security
A new multi-stage attack has been observed delivering malware families like Agent Tesla variants, Remcos RAT, and XLoader. "Attackers increasingly rely on such complex delivery mechanisms to evade detection, bypass traditional sandboxes, and ensure successful payload delivery and execution," Palo Alto Networks Unit 42 researcher Saqib Khanzada said in a technical write-up of the campaign. The starting point of the attack is a deceptive email that poses as an order request to deliver a malicious 7-zip archive attachment, which contains a JavaScript encoded (.JSE) file. The phishing email, observed in December 2024, falsely claimed that a payment had been made and urged the recipient to review an attached order file. Launching the JavaScript payload triggers the infection sequence, with the file acting as a downloader for a PowerShell script from an external server. The script, in turn, houses a Base64-encoded payload that's subsequently deciphered, written to the Wi...
State-Sponsored Hackers Weaponize ClickFix Tactic in Targeted Malware Campaigns

State-Sponsored Hackers Weaponize ClickFix Tactic in Targeted Malware Campaigns

Apr 17, 2025 Social Engineering / Malware
Multiple state-sponsored hacking groups from Iran, North Korea, and Russia have been found leveraging the increasingly popular ClickFix social engineering tactic to deploy malware over a three-month period from late 2024 through the beginning of 2025. The phishing campaigns adopting the strategy have been attributed to clusters tracked as TA427 (aka Kimsuky), TA450 (aka MuddyWater), UNK_RemoteRogue, and TA422 (aka APT28). ClickFix has been an initial access technique primarily affiliated with cybercrime groups, although the effectiveness of the approach has led to it also being adopted by nation-state groups. "The incorporation of ClickFix is not revolutionizing the campaigns carried out by TA427, TA450, UNK_RemoteRogue, and TA422 but instead is replacing the installation and execution stages in existing infection chains," enterprise security firm Proofpoint said in a report published today. ClickFix , in a nutshell, refers to a sneaky technique that tricks users int...
Node.js Malware Campaign Targets Crypto Users with Fake Binance and TradingView Installers

Node.js Malware Campaign Targets Crypto Users with Fake Binance and TradingView Installers

Apr 17, 2025 Cybersecurity / Malware
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...

Gamaredon Uses Infected Removable Drives to Breach Western Military Mission in Ukraine

Apr 10, 2025 Cyber Espionage / Malware
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...

Cryptocurrency Miner and Clipper Malware Spread via SourceForge Cracked Software Listings

Apr 08, 2025 Cryptocurrency / Malware
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...
