Fake Job Applications Deliver Dangerous More_eggs Malware to HR Professionals

Fake Job Applications Deliver Dangerous More_eggs Malware to HR Professionals

Oct 02, 2024 Cybercrime / Threat Intelligence
A spear-phishing email campaign has been observed targeting recruiters with a JavaScript backdoor called More_eggs, indicating persistent efforts to single out the sector under the guise of fake job applications. "A sophisticated spear-phishing lure tricked a recruitment officer into downloading and executing a malicious file disguised as a resume, leading to a more_eggs backdoor infection," Trend Micro researchers Ryan Soliven, Maria Emreen Viray, and Fe Cureg said in an analysis. More_eggs, sold as a malware-as-a-service (MaaS), is a malicious software that comes with capabilities to siphon credentials, including those related to online bank accounts, email accounts, and IT administrator accounts. It's attributed to a threat actor called the Golden Chickens group (aka Venom Spider), and has been put to use by several other e-crime groups like FIN6 (aka ITG08 ), Cobalt, and Evilnum. Earlier this June, eSentire disclosed details of a similar attack that leverages
North Korean Hackers Moonstone Sleet Push Malicious JS Packages to npm Registry

North Korean Hackers Moonstone Sleet Push Malicious JS Packages to npm Registry

Aug 06, 2024 Malware / Windows Security
The North Korea-linked threat actor known as Moonstone Sleet has continued to push malicious npm packages to the JavaScript package registry with the aim of infecting Windows systems, underscoring the persistent nature of their campaigns. The packages in question, harthat-api and harthat-hash , were published on July 7, 2024, according to Datadog Security Labs. Both the libraries did not attract any downloads and were shortly pulled after a brief period of time. The security arm of the cloud monitoring firm is tracking the threat actor under the name Stressed Pungsan, which exhibits overlaps with a newly discovered North Korean malicious activity cluster dubbed Moonstone Sleet. "While the name resembles the Hardhat npm package (an Ethereum development utility), its content does not indicate any intention to typosquat it," Datadog researchers Sebastian Obregoso and Zack Allen said . "The malicious package reuses code from a well-known GitHub repository called node-

SocGholish Malware Exploits BOINC Project for Covert Cyberattacks

Jul 22, 2024 Vulnerability / Malware
The JavaScript downloader malware known as SocGholish (aka FakeUpdates) is being used to deliver a remote access trojan called AsyncRAT as well as a legitimate open-source project called BOINC. BOINC , short for Berkeley Open Infrastructure Network Computing Client, is an open-source "volunteer computing" platform maintained by the University of California with an aim to carry out "large-scale distributed high-throughput computing" using participating home computers on which the app is installed. "It's similar to a cryptocurrency miner in that way (using computer resources to do work), and it's actually designed to reward users with a specific type of cryptocurrency called Gridcoin, designed for this purpose," Huntress researchers Matt Anderson, Alden Schmidt, and Greg Linares said in a report published last week. These malicious installations are designed to connect to an actor-controlled domain ("rosettahome[.]cn" or "rosettah

Trojanized jQuery Packages Found on npm, GitHub, and jsDelivr Code Repositories

Trojanized jQuery Packages Found on npm, GitHub, and jsDelivr Code Repositories

Jul 09, 2024 Supply Chain Attack / Web Security
Unknown threat actors have been found propagating trojanized versions of jQuery on npm, GitHub, and jsDelivr in what appears to be an instance of a "complex and persistent" supply chain attack. "This attack stands out due to the high variability across packages," Phylum said in an analysis published last week. "The attacker has cleverly hidden the malware in the seldom-used ' end ' function of jQuery, which is internally called by the more popular ' fadeTo ' function from its animation utilities." As many as 68 packages have been linked to the campaign. They were published to the npm registry starting from May 26 to June 23, 2024, using names such as cdnjquery, footersicons, jquertyi, jqueryxxx, logoo, and sytlesheets, among others.  There is evidence to suggest that each of the bogus packages were manually assembled and published due to the sheer number of packages published from various accounts, the differences in naming conventi

Polyfill[.]io Attack Impacts Over 380,000 Hosts, Including Major Companies

Jul 05, 2024 Supply Chain Attack / Malware
The supply chain attack targeting the widely-used Polyfill[.]io JavaScript library is broader in scope than previously thought, with new findings from Censys showing that over 380,000 hosts are embedding a polyfill script linking to the malicious domain as of July 2, 2024. This includes references to "https://cdn.polyfill[.]io" or "https://cdn.polyfill[.]com" in their HTTP responses, the attack surface management firm said. "Approximately 237,700, are located within the Hetzner network (AS24940), primarily in Germany," it noted. "This is not surprising – Hetzner is a popular web hosting service, and many website developers leverage it." Further analysis of the affected hosts has revealed domains tied to prominent companies like WarnerBros, Hulu, Mercedes-Benz, and Pearson that reference the malicious endpoint in question. Details of the attack emerged in late June 2024 when Sansec alerted that code hosted on the Polyfill domain had been m
New Cyberthreat 'Boolka' Deploying BMANAGER Trojan via SQLi Attacks

New Cyberthreat 'Boolka' Deploying BMANAGER Trojan via SQLi Attacks

Jun 25, 2024 Data Theft / Web Security
A previously undocumented threat actor dubbed Boolka has been observed compromising websites with malicious scripts to deliver a modular trojan codenamed BMANAGER . "The threat actor behind this campaign has been carrying out opportunistic SQL injection attacks against websites in various countries since at least 2022," Group-IB researchers Rustam Mirkasymov and Martijn van den Berk said in a report published last week. "Over the last three years, the threat actors have been infecting vulnerable websites with malicious JavaScript scripts capable of intercepting any data entered on an infected website." Boolka gets its name from the JavaScript code inserted into the website that beacons out to a command-and-control server named "boolka[.]tk" every time an unsuspecting visitor lands on the infected site. The JavaScript is also designed to collect and exfiltrate user inputs and interactions in a Base64-encoded format, indicating the use of the malware
The End of an Era: Microsoft Phases Out VBScript for JavaScript and PowerShell

The End of an Era: Microsoft Phases Out VBScript for JavaScript and PowerShell

May 23, 2024 Endpoint Security / Data Privacy
Microsoft on Wednesday outlined its plans to deprecate Visual Basic Script (VBScript) in the second half of 2024 in favor of more advanced alternatives such as JavaScript and PowerShell. "Technology has advanced over the years, giving rise to more powerful and versatile scripting languages such as JavaScript and PowerShell," Microsoft Program Manager Naveen Shankar  said . "These languages offer broader capabilities and are better suited for modern web development and automation tasks." The tech giant originally  announced  its plans to gradually sunset VBScript in October 2023. The scripting language, also called Visual Basic Scripting Edition, was first introduced by Microsoft in 1996 as a Windows system component, offering users the ability to automate tasks and develop interactive web pages using Internet Explorer and Edge (in  Internet Explorer mode ). The announced deprecation plan consists of three phases, with the first phase kicking off in the second h

Google Patches Yet Another Actively Exploited Chrome Zero-Day Vulnerability

May 16, 2024 Browser Security / Vulnerability
Google has rolled out fixes to address a set of nine security issues in its Chrome browser, including a new zero-day that has been exploited in the wild. Assigned the CVE identifier  CVE-2024-4947 , the vulnerability relates to a type confusion bug in the V8 JavaScript and WebAssembly engine. It was reported by Kaspersky researchers Vasily Berdnikov and Boris Larin on May 13, 2024. Type confusion vulnerabilities  arise when a program attempts to access a resource with an incompatible type. It can have  serious impacts  as it allows threat actors to perform out-of-bounds memory access, cause a crash, and execute arbitrary code. The development marks the third zero-day that Google has patched within a week after  CVE-2024-4671  and  CVE-2024-4761 . As is typically the case, no additional details about the attacks are available and have been withheld to prevent further exploitation. "Google is aware that an exploit for CVE-2024-4947 exists in the wild," the company  said .

Researchers Detail Multistage Attack Hijacking Systems with SSLoad, Cobalt Strike

Apr 24, 2024 Malware / Endpoint Security
Cybersecurity researchers have discovered an ongoing attack campaign that's leveraging phishing emails to deliver a malware called SSLoad . The campaign, codenamed  FROZEN#SHADOW  by Securonix, also involves the deployment of Cobalt Strike and the ConnectWise ScreenConnect remote desktop software. "SSLoad is designed to stealthily infiltrate systems, gather sensitive information and transmit its findings back to its operators," security researchers Den Iuzvyk, Tim Peck, and Oleg Kolesnikov said in a report shared with The Hacker News. "Once inside the system, SSLoad deploys multiple backdoors and payloads to maintain persistence and avoid detection." Attack chains involve the use of phishing messages to randomly target organizations in Asia, Europe, and the Americas, with emails containing links that lead to the retrieval of a JavaScript file that kicks off the infection flow. Earlier this month, Palo Alto Networks uncovered at least two different method

OpenJS Foundation Targeted in Potential JavaScript Project Takeover Attempt

Apr 16, 2024 Supply Chain / Software Security
Security researchers have uncovered a "credible" takeover attempt targeting the OpenJS Foundation in a manner that evokes similarities to the recently uncovered incident aimed at the open-source XZ Utils project. "The OpenJS Foundation Cross Project Council received a suspicious series of emails with similar messages, bearing different names and overlapping GitHub-associated emails," OpenJS Foundation and Open Source Security Foundation (OpenSSF)  said  in a joint alert. According to Robin Bender Ginn, executive director of OpenJS Foundation, and Omkhar Arasaratnam, general manager at OpenSSF, the email messages urged OpenJS to take action to update one of its popular JavaScript projects to remediate critical vulnerabilities without providing any specifics. The email author(s) also called on OpenJS to designate them as a new maintainer of the project despite having little prior involvement. Two other popular JavaScript projects not hosted by OpenJS are also sai
Sneaky Credit Card Skimmer Disguised as Harmless Facebook Tracker

Sneaky Credit Card Skimmer Disguised as Harmless Facebook Tracker

Apr 12, 2024 Web Security / WordPress
Cybersecurity researchers have discovered a credit card skimmer that's concealed within a fake  Meta Pixel tracker script  in an attempt to evade detection. Sucuri said that the malware is injected into websites through tools that allow for custom code, such as WordPress plugins like  Simple Custom CSS and JS  or the " Miscellaneous Scripts " section of the Magento admin panel. "Custom script editors are popular with bad actors because they allow for external third party (and malicious) JavaScript and can easily pretend to be benign by leveraging naming conventions that match popular scripts like Google Analytics or libraries like JQuery," security researcher Matt Morrow  said . The bogus Meta Pixel tracker script identified by the web security company contains similar elements as its legitimate counterpart, but a closer examination reveals the addition of JavaScript code that substitutes references to the domain "connect.facebook[.]net" with "
Google Chrome Adds V8 Sandbox - A New Defense Against Browser Attacks

Google Chrome Adds V8 Sandbox - A New Defense Against Browser Attacks

Apr 08, 2024 Software Security / Cybersecurity
Google has announced support for what's called a  V8 Sandbox  in the Chrome web browser in an effort to address memory corruption issues. The sandbox, according to V8 security technical lead Samuel Groß,  aims  to prevent "memory corruption in V8 from spreading within the host process." The search behemoth has  described  V8 Sandbox as a lightweight, in-process sandbox for the JavaScript and WebAssembly engine that's designed to mitigate common V8 vulnerabilities. The idea is to limit the impact of V8 vulnerabilities by restricting the code executed by V8 to a subset of the process' virtual address space ("the sandbox") and isolating it from the rest of the process. Shortcomings affecting V8 have accounted for a significant chunk of the zero-day vulnerabilities that Google has  addressed  between  2021  and  2023 , with as many as 16 security flaws discovered over the time period. "The sandbox assumes that an attacker can arbitrarily and conc

New Wave of JSOutProx Malware Targeting Financial Firms in APAC and MENA

Apr 05, 2024 Cyber Espionage / Cybersecurity
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 out
Microsoft Edge Bug Could Have Allowed Attackers to Silently Install Malicious Extensions

Microsoft Edge Bug Could Have Allowed Attackers to Silently Install Malicious Extensions

Mar 27, 2024 Vulnerability / API Security
A now-patched security flaw in the Microsoft Edge web browser could have been abused to install arbitrary extensions on users' systems and carry out malicious actions.  "This flaw could have allowed an attacker to exploit a private API, initially intended for marketing purposes, to covertly install additional browser extensions with broad permissions without the user's knowledge," Guardio Labs security researcher Oleg Zaytsev  said  in a new report shared with The Hacker News. Tracked as  CVE-2024-21388  (CVSS score: 6.5), it was addressed by Microsoft in Edge stable version 121.0.2277.83 released on January 25, 2024, following responsible disclosure in November 2023. The Windows maker credited both Zaytsev and Jun Kokatsu for reporting the issue. "An attacker who successfully exploited this vulnerability could gain the privileges needed to install an extension," Microsoft said in an advisory for the flaw, adding it "could lead to a browser sandbo
Massive Sign1 Campaign Infects 39,000+ WordPress Sites with Scam Redirects

Massive Sign1 Campaign Infects 39,000+ WordPress Sites with Scam Redirects

Mar 22, 2024 Web Security / Vulnerability
A massive malware campaign dubbed  Sign1  has compromised over 39,000 WordPress sites in the last six months, using malicious JavaScript injections to redirect users to scam sites. The most recent variant of the malware is estimated to have infected no less than 2,500 sites over the past two months alone, Sucuri said in a report published this week. The attacks entail injecting rogue JavaScript into legitimate HTML widgets and plugins that allow for arbitrary JavaScript and other code to be inserted, providing attackers with an opportunity to add their malicious code. The XOR-encoded JavaScript code is subsequently decoded and used to execute a JavaScript file hosted on a remote server, which ultimately facilitates redirects to a  VexTrio -operated traffic distribution system (TDS) but only if certain criteria are met. What's more, the malware uses time-based randomization to fetch dynamic URLs that change every 10 minutes to get around blocklists. These domains are registere
Hacked WordPress Sites Abusing Visitors' Browsers for Distributed Brute-Force Attacks

Hacked WordPress Sites Abusing Visitors' Browsers for Distributed Brute-Force Attacks

Mar 07, 2024 Vulnerability / Web Security
Threat actors are conducting brute-force attacks against WordPress sites by leveraging malicious JavaScript injections, new findings from Sucuri reveal. The attacks, which take the form of distributed brute-force attacks, "target WordPress websites from the browsers of completely innocent and unsuspecting site visitors," security researcher Denis Sinegubko  said . The activity is part of a  previously documented attack wave  in which compromised WordPress sites were used to inject crypto drainers such as Angel Drainer directly or redirect site visitors to Web3 phishing sites containing drainer malware. The latest iteration is notable for the fact that the injections – found on  over 700 sites  to date – don't load a drainer but rather use a list of common and leaked passwords to brute-force other WordPress sites. The attack unfolds over five stages, enabling a threat actor to take advantage of already compromised websites to launch distributed brute-force attacks against other po
New Backdoor Targeting European Officials Linked to Indian Diplomatic Events

New Backdoor Targeting European Officials Linked to Indian Diplomatic Events

Feb 29, 2024 Cyber Espionage / Malware
A previously undocumented threat actor dubbed  SPIKEDWINE  has been observed targeting officials in European countries with Indian diplomatic missions using a new backdoor called WINELOADER . The adversary, according to a  report  from Zscaler ThreatLabz, used a PDF file in emails that purported to come from the Ambassador of India, inviting diplomatic staff to a wine-tasting event on February 2, 2024. The  PDF document  was uploaded to VirusTotal from Latvia on January 30, 2024. That said, there is evidence to suggest that this campaign may have been active at least since July 6, 2023, going by the discovery of  another similar PDF file  uploaded from the same country. "The attack is characterized by its very low volume and the advanced tactics, techniques, and procedures (TTPs) employed in the malware and command-and-control (C2) infrastructure," security researchers Sudeep Singh and Roy Tay said. Central to the novel attack is the PDF file that comes embedded with a malicious
