A new phishing campaign has set its eyes on the Latin American region to deliver malicious payloads to Windows systems. "The phishing email contained a ZIP file attachment that when extracted reveals an HTML file that leads to a malicious file download posing as an invoice," Trustwave SpiderLabs researcher Karla Agregado  said . The email message, the company said, originates from an email address format that uses the domain "temporary[.]link" and has Roundcube Webmail listed as the User-Agent string. The HTML file points containing a link ("facturasmex[.]cloud") that displays an error message saying "this account has been suspended," but when visited from an IP address geolocated to Mexico, loads a CAPTCHA verification page that uses Cloudflare Turnstile. This step paves the way for a redirect to another domain from where a malicious RAR file is downloaded. The RAR archive comes with a PowerShell script that gathers system metadata as well...

Google has filed a lawsuit in the U.S. against two app developers for allegedly engaging in an "international online consumer investment fraud scheme" that tricked users into downloading bogus Android apps from the Google Play Store and other sources and stealing their funds under the guise of promising higher returns. The individuals in question are Yunfeng Sun (aka Alphonse Sun) and Hongnam Cheung (aka Zhang Hongnim or Stanford Fischer), who are believed to be based in Shenzhen and Hong Kong, respectively. The defendants are said to have uploaded about 87 crypto apps to the Play Store to pull off the social engineering scam since at least 2019, with over 100,000 users downloading them and leading to substantial financial losses. "The gains conveyed by the apps were illusory," the tech giant said in its complaint. "And the scheme did not end there." "Instead, when individual victims attempted to withdraw their balances, defendants and their co...

Threat actors have been found exploiting a critical flaw in Magento to inject a persistent backdoor into e-commerce websites. The attack leverages  CVE-2024-20720  (CVSS score: 9.1), which has been described by Adobe as a case of "improper neutralization of special elements" that could pave the way for arbitrary code execution. It was  addressed  by the company as part of security updates released on February 13, 2024. Sansec said it discovered a "cleverly crafted layout template in the database" that's being used to automatically inject malicious code to execute arbitrary commands. "Attackers combine the Magento layout parser with the beberlei/assert package (installed by default) to execute system commands," the company  said . "Because the layout block is tied to the checkout cart, this command is executed whenever <store>/checkout/cart is requested." The command in question is  sed , which is used to insert a code execution ...

New research has found that artificial intelligence (AI)-as-a-service providers such as Hugging Face are susceptible to two critical risks that could allow threat actors to escalate privileges, gain cross-tenant access to other customers' models, and even take over the continuous integration and continuous deployment (CI/CD) pipelines. "Malicious models represent a major risk to AI systems, especially for AI-as-a-service providers because potential attackers may leverage these models to perform cross-tenant attacks," Wiz researchers Shir Tamari and Sagi Tzadik  said . "The potential impact is devastating, as attackers may be able to access the millions of private AI models and apps stored within AI-as-a-service providers." The development comes as machine learning pipelines have emerged as a brand new supply chain attack vector, with repositories like Hugging Face becoming an attractive target for staging adversarial attacks designed to glean sensitive infor...

Bogus installers for Adobe Acrobat Reader are being used to  distribute  a new multi-functional malware dubbed  Byakugan . The starting point of the attack is a PDF file written in Portuguese that, when opened, shows a blurred image and asks the victim to click on a link to download the Reader application to view the content. According to Fortinet FortiGuard Labs, clicking the URL leads to the delivery of an installer ("Reader_Install_Setup.exe") that activates the infection sequence. Details of the campaign were  first disclosed  by the AhnLab Security Intelligence Center (ASEC) last month. The attack chain leverages techniques like DLL hijacking and Windows User Access Control (UAC) bypass to load a malicious dynamic-link library (DLL) file named "BluetoothDiagnosticUtil.dll," which, in turn, loads unleashes the final payload. It also deploys a legitimate installer for a PDF reader like Wondershare PDFelement. The binary is equipped to gather and exfiltra...

Financial organizations in the Asia-Pacific (APAC) and Middle East and North Africa (MENA) are being targeted by a new version of an "evolving threat" called  JSOutProx . "JSOutProx is a sophisticated attack framework utilizing both JavaScript and .NET," Resecurity  said  in a technical report published this week. "It employs the .NET (de)serialization feature to interact with a core JavaScript module running on the victim's machine. Once executed, the malware enables the framework to load various plugins, which conduct additional malicious activities on the target." First  identified  in December 2019 by Yoroi, early attacks distributing JSOutProx have been attributed to a threat actor tracked as  Solar Spider . The cyber crime actors behind the malware have a track record of striking banks and other big companies in Asia and Europe. In late 2021, Quick Heal Security Labs  detailed  attacks leveraging the remote access trojan (RAT) to single...

Multiple China-nexus threat actors have been linked to the zero-day exploitation of three security flaws impacting Ivanti appliances (CVE-2023-46805, CVE-2024-21887, and CVE-2024-21893). The clusters are being tracked by Mandiant under the uncategorized monikers  UNC5221 , UNC5266, UNC5291,  UNC5325 , UNC5330, and UNC5337. Also previously linked to the exploitation spree is a Chinese hacking crew called UNC3886 , whose tradecraft is notable for weaponizing zero-day bugs in Fortinet and VMware to breach target networks. The Google Cloud subsidiary said it has also observed financially motivated actors exploiting CVE-2023-46805 and CVE-2024-21887, likely in an attempt to conduct cryptocurrency mining operations. "UNC5266 overlaps in part with UNC3569, a China-nexus espionage actor that has been observed exploiting vulnerabilities in Aspera Faspex, Microsoft Exchange, and Oracle Web Applications Desktop Integrator, among others, to gain initial access to target environments,...
