The Colombian insurance sector is the target of a threat actor tracked as Blind Eagle with the end goal of delivering a customized version of a known commodity remote access trojan (RAT) referred to as Quasar RAT since June 2024. "Attacks have originated with phishing emails impersonating the Colombian tax authority," Zscaler ThreatLabz researcher Gaetano Pellegrino said in a new analysis published last week. The advanced persistent threat (APT), also known as AguilaCiega, APT-C-36, and APT-Q-98, has a track record of focusing on organizations and individuals in South America, particularly related to the government and finance sectors in Colombia and Ecuador. The attack chains, as recently documented by Kaspersky, originate with phishing emails that entice recipients into clicking on malicious links that serve as the launchpad for the infection process. The links, either embedded within a PDF attachment or directly in the email body, point to ZIP archives hosted on

Two men have been indicted in the U.S. for their alleged involvement in managing a dark web marketplace called WWH Club that specializes in the sale of sensitive personal and financial information. Alex Khodyrev, a 35-year-old Kazakhstan national, and Pavel Kublitskii, a 37-year-old Russian national, have been charged with conspiracy to commit access device fraud and conspiracy to commit wire fraud. Khodyrev and Kublitskii, between 2014 and 2024, acted as the main administrators of WWH Club (wwh-club[.]ws) and various other sister sites – wwh-club[.]net, center-club[.]pw, opencard[.]pw, skynetzone[.]org – that functioned as dark web marketplaces, forums, and training centers to enable cybercrime. The indictment follows an investigation launched by the U.S. Federal Bureau of Investigation (FBI) in July 2020 after determining that WWH Club's primary domain (www-club[.]ws]) resolved to an IP address belonging to DigitalOcean, allowing them to issue a federal search warrant to t

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

A non-profit supporting Vietnamese human rights has been the target of a multi-year campaign designed to deliver a variety of malware on compromised hosts. Cybersecurity company Huntress attributed the activity to a threat cluster tracked as APT32, a Vietnamese-aligned hacking crew that's also known as APT-C-00, Canvas Cyclone (formerly Bismuth), Cobalt Kitty, and OceanLotus. The intrusion is believed to have been ongoing for at least four years. "This intrusion has a number of overlaps with known techniques used by the threat actor APT32/OceanLotus, and a known target demographic which aligns with APT32/OceanLotus targets," security researchers Jai Minton and Craig Sweeney said . OceanLotus , active since at least 2012, has a history of targeting company and government networks in East-Asian countries, particularly Vietnam, the Philippines, Laos, and Cambodia with the end goal of cyber espionage and intellectual property theft. Attack chains typically make use of

Users of Chinese instant messaging apps like DingTalk and WeChat are the target of an Apple macOS version of a backdoor named HZ RAT . The artifacts "almost exactly replicate the functionality of the Windows version of the backdoor and differ only in the payload, which is received in the form of shell scripts from the attackers' server," Kaspersky researcher Sergey Puzan said . HZ RAT was first documented by German cybersecurity company DCSO in November 2022, with the malware distributed via self-extracting zip archives or malicious RTF documents presumably built using the Royal Road RTF weaponizer . The attack chains involving RTF documents are engineered to deploy the Windows version of the malware that's executed on the compromised host by exploiting a years-old Microsoft Office flaw in the Equation Editor ( CVE-2017-11882 ). The second distribution method, on the other hand, masquerades as an installer for legitimate software such as OpenVPN, PuTTYgen, or E

Cybersecurity researchers have uncovered new Android malware that can relay victims' contactless payment data from physical credit and debit cards to an attacker-controlled device with the goal of conducting fraudulent operations. The Slovak cybersecurity company is tracking the novel malware as NGate, stating it observed the crimeware campaign targeting three banks in Czechia. The malware "has the unique ability to relay data from victims' payment cards, via a malicious app installed on their Android devices, to the attacker's rooted Android phone," researchers Lukáš Štefanko and Jakub Osmani said in an analysis. The activity is part of a broader campaign that has been found to target financial institutions in Czechia since November 2023 using malicious progressive web apps (PWAs) and WebAPKs. The first recorded use of NGate was in March 2024. The end goal of the attacks is to clone near-field communication (NFC) data from victims' physical payment ca

A 33-year-old Latvian national living in Moscow, Russia, has been charged in the U.S. for allegedly stealing data, extorting victims, and laundering ransom payments since August 2021. Deniss Zolotarjovs (aka Sforza_cesarini) has been charged with conspiring to commit money laundering, wire fraud and Hobbs Act extortion. He was arrested in Georgia in December 2023 and has since been extradited to the U.S. as of this month. "Zolotarjovs is a member of a known cybercriminal organization that attacks computer systems of victims around the world," the U.S. Department of Justice (DoJ) said in a press release this week. "Among other things, the Russian cybercrime group steals victim data and threatens to release it unless the victim pays ransom in cryptocurrency. The group maintains a leaks and auction website that lists victim companies and offers stolen data for download." Zolotarjovs is believed to have been an active member of the e-crime group, engaging with ot

In what's a case of an operational security (OPSEC) lapse, the operator behind a new information stealer called Styx Stealer leaked data from their own computer, including details related to the clients, profit information, nicknames, phone numbers, and email addresses. Styx Stealer, a derivative of the Phemedrone Stealer , is capable of stealing browser data, instant messenger sessions from Telegram and Discord, and cryptocurrency wallet information, cybersecurity company Check Point said in an analysis. It first emerged in April 2024. "Styx Stealer is most likely based on the source code of an old version of Phemedrone Stealer, which lacks some features found in newer versions such as sending reports to Telegram, report encryption, and more," the company noted . "However, the creator of Styx Stealer added some new features: auto-start, clipboard monitor and crypto-clipper, additional sandbox evasion, and anti-analysis techniques, and re-implemented sending dat

The Computer Emergency Response Team of Ukraine (CERT-UA) has warned of new phishing attacks that aim to infect devices with malware. The activity has been attributed to a threat cluster it tracks as UAC-0020, which is also known as Vermin . The exact scale and scope of the attacks are presently unknown. The attack chains commence with phishing messages with photos of alleged prisoners of war (PoWs) from the Kursk region, urging recipients to click on a link pointing to a ZIP archive. The ZIP file contains a Microsoft Compiled HTML Help (CHM) file that embeds JavaScript code responsible for launching an obfuscated PowerShell script. "Opening the file installs components of known spyware SPECTR, as well as the new malware called FIRMACHAGENT," CERT-UA said. "The purpose of FIRMACHAGENT is to retrive the data stolen by SPECTR and send it to a remote management server." SPECTR is a known malware linked to Vermin as far back as 2019. The group is assessed to be

Mobile users in the Czech Republic are the target of a novel phishing campaign that leverages a Progressive Web Application (PWA) in an attempt to sidestep security protections and steal their banking account credentials. The attacks have targeted the Czech-based Československá obchodní banka (CSOB), as well as the Hungarian OTP Bank and a Georgian Bank, according to Slovak cybersecurity company ESET. "The phishing websites targeting iOS instruct victims to add a Progressive Web Application ( PWA ) to their home-screens, while on Android the PWA is installed after confirming custom pop-ups in the browser," security researcher Jakub Osmani said . "At this point, on both operating systems, these phishing apps are largely indistinguishable from the real banking apps that they mimic." What's notable about this tactic is that users are deceived into installing a PWA, or even WebAPKs in some cases on Android, from a third-party site without having to specificall

Cybersecurity researchers have shed light on a sophisticated information stealer campaign that impersonates legitimate brands to distribute malware like DanaBot and StealC . The activity cluster, orchestrated by Russian-speaking cybercriminals and collectively codenamed Tusk, is said to encompass several sub-campaigns, leveraging the reputation of the platforms to trick users into downloading the malware using bogus sites and social media accounts. "All the active sub-campaigns host the initial downloader on Dropbox," Kaspersky researchers Elsayed Elrefaei and AbdulRhman Alfaifi said . "This downloader is responsible for delivering additional malware samples to the victim's machine, which are mostly info-stealers (DanaBot and StealC) and clippers." Of the 19 sub-campaigns identified to date, three are said to be currently active. The name "Tusk" is a reference to the word "Mammoth" used by the threat actors in log messages associated with t

Cybersecurity researchers have uncovered new stealer malware that's designed to specifically target Apple macOS systems. Dubbed Banshee Stealer, it's offered for sale in the cybercrime underground for a steep price of $3,000 a month and works across both x86_64 and ARM64 architectures.  "Banshee Stealer targets a wide range of browsers, cryptocurrency wallets, and around 100 browser extensions, making it a highly versatile and dangerous threat," Elastic Security Labs said in a Thursday report. The web browsers and crypto wallets targeted by the malware comprise Safari, Google Chrome, Mozilla Firefox, Brave, Microsoft Edge, Vivaldi, Yandex, Opera, OperaGX, Exodus, Electrum, Coinomi, Guarda, Wasabi Wallet, Atomic, and Ledger. It's also equipped to harvest system information and data from iCloud Keychain passwords and Notes, as well as incorporate a slew of anti-analysis and anti-debugging measures to determine if it's running in a virtual environment in a

A previously unknown threat actor has been attributed to a spate of attacks targeting Azerbaijan and Israel with an aim to steal sensitive data. The attack campaign, detected by NSFOCUS on July 1, 2024, leveraged spear-phishing emails to single out Azerbaijani and Israeli diplomats. The activity is being tracked under the moniker Actor240524 . "Actor240524 possesses the ability to steal secrets and modify file data, using a variety of countermeasures to avoid overexposure of attack tactics and techniques," the cybersecurity company said in an analysis published last week. The attack chains commence with the use of phishing emails bearing Microsoft Word documents that, upon opening, urge the recipients to " Enable Content " and run a malicious macro responsible for executing an intermediate loader payload codenamed ABCloader ("MicrosoftWordUpdater.log"). In the next step, ABCloader acts as a conduit to decrypt and load a DLL malware called ABCsync (&

The Russian government and IT organizations are the target of a new campaign that delivers a number of backdoors and trojans as part of a spear-phishing campaign codenamed EastWind . The attack chains are characterized by the use of RAR archive attachments containing a Windows shortcut (LNK) file that, upon opening, activates the infection sequence, culminating in the deployment of malware such as GrewApacha, an updated version of the CloudSorcerer backdoor, and a previously undocumented implant dubbed PlugY. PlugY is "downloaded through the CloudSorcerer backdoor, has an extensive set of commands and supports three different protocols for communicating with the command-and-control server," Russian cybersecurity company Kaspersky said . The initial infection vector relies on a booby-trapped LNK file, which employs DLL side-loading techniques to launch a malicious DLL file that uses Dropbox as a communications mechanism to execute reconnaissance commands and download add

An ongoing, widespread malware campaign has been observed installing rogue Google Chrome and Microsoft Edge extensions via a trojan distributed via fake websites masquerading as popular software. "The trojan malware contains different deliverables ranging from simple adware extensions that hijack searches to more sophisticated malicious scripts that deliver local extensions to steal private data and execute various commands," the ReasonLabs research team said in an analysis. "This trojan malware, existing since 2021, originates from imitations of download websites with add-ons to online games and videos." The malware and the extensions have a combined reach of at least 300,000 users of Google Chrome and Microsoft Edge, indicating that the activity has a broad impact. At the heart of the campaign is the use of malvertising to push lookalike websites promoting known software like Roblox FPS Unlocker, YouTube, VLC media player, Steam, or KeePass to trick users s

Cybersecurity researchers have discovered a novel phishing campaign that leverages Google Drawings and shortened links generated via WhatsApp to evade detection and trick users into clicking on bogus links designed to steal sensitive information. "The attackers chose a group of the best-known websites in computing to craft the threat, including Google and WhatsApp to host the attack elements, and an Amazon look-alike to harvest the victim's information," Menlo Security researcher Ashwin Vamshi said . "This attack is a great example of a Living Off Trusted Sites ( LoTS ) threat." The starting point of the attack is a phishing email that directs the recipients to a graphic that appears to be an Amazon account verification link. This graphic, for its part, is hosted on Google Drawings, in an apparent effort to evade detection. Abusing legitimate services has obvious benefits for attackers in that they're not only a low-cost solution, but more importantly,

The threat actors behind an ongoing malware campaign targeting software developers have demonstrated new malware and tactics, expanding their focus to include Windows, Linux, and macOS systems. The activity cluster, dubbed DEV#POPPER and linked to North Korea, has been found to have singled out victims across South Korea, North America, Europe, and the Middle East. "This form of attack is an advanced form of social engineering, designed to manipulate individuals into divulging confidential information or performing actions that they might normally not," Securonix researchers Den Iuzvyk and Tim Peck said in a new report shared with The Hacker News. DEV#POPPER is the moniker assigned to an active malware campaign that tricks software developers into downloading booby-trapped software hosted on GitHub under the guise of a job interview. It shares overlaps with a campaign tracked by Palo Alto Networks Unit 42 under the name Contagious Interview . Signs that the campaign

The remote access trojan known as Gh0st RAT has been observed being delivered by an "evasive dropper" called Gh0stGambit as part of a drive-by download scheme targeting Chinese-speaking Windows users. These infections stem from a fake website ("chrome-web[.]com") serving malicious installer packages masquerading as Google's Chrome browser, indicating that users searching for the software on the web are being singled out. Gh0st RAT is a long-standing malware that has been observed in the wild since 2008, manifesting in the form of different variants over the years in campaigns primarily orchestrated by China-nexus cyberespionage groups. Some iterations of the trojan have also been previously deployed by infiltrating poorly-secured MS SQL server instances, using it as a conduit to install the Hidden open-source rootkit. According to cybersecurity firm eSentire, which discovered the latest activity, the targeting of Chinese-speaking users is based on &quo

Several organizations operating within global shipping and logistics, media and entertainment, technology, and automotive sectors in Italy, Spain, Taiwan, Thailand, Turkey, and the U.K. have become the target of a "sustained campaign" by the prolific China-based APT41 hacking group. "APT41 successfully infiltrated and maintained prolonged, unauthorized access to numerous victims' networks since 2023, enabling them to extract sensitive data over an extended period," Google-owned Mandiant said in a new report published Thursday. The threat intelligence firm described the adversarial collective as unique among China-nexus actors owing to its use of "non-public malware typically reserved for espionage operations in activities that appear to fall outside the scope of state-sponsored missions." Attack chains involve the use of web shells (ANTSWORD and BLUEBEAM), custom droppers (DUSTPAN and DUSTTRAP), and publicly available tools (SQLULDR2 and PINEGROV

Cybersecurity researchers have discovered an updated variant of a known stealer malware that attackers affiliated with the Democratic People's Republic of Korea (DPRK) have delivered as part of prior cyber espionage campaigns targeting job seekers. The artifact in question is an Apple macOS disk image (DMG) file named "MiroTalk.dmg" that mimics the legitimate video call service of the same name, but, in reality, serves as a conduit to deliver a native version of BeaverTail, security researcher Patrick Wardle said . BeaverTail refers to a JavaScript stealer malware that was first documented by Palo Alto Networks Unit 42 in November 2023 as part of a campaign dubbed Contagious Interview that aims to infect software developers with malware through a supposed job interview process. Securonix is tracking the same activity under the moniker DEV#POPPER . Besides siphoning sensitive information from web browsers and crypto wallets, the malware is capable of delivering addi
