As many as 77 banking institutions, cryptocurrency exchanges, and national organizations have become the target of a newly discovered Android remote access trojan (RAT) called DroidBot . "DroidBot is a modern RAT that combines hidden VNC and overlay attack techniques with spyware-like capabilities, such as keylogging and user interface monitoring," Cleafy researchers Simone Mattia, Alessandro Strino, and Federico Valentini said . "Moreover, it leverages dual-channel communication, transmitting outbound data through MQTT and receiving inbound commands via HTTPS, providing enhanced operation flexibility and resilience." The Italian fraud prevention company said it discovered the malware in late October 2024, although there is evidence to suggest that it has been active since at least June, operating under a malware-as-a-service (MaaS) model for a monthly fee of $3,000. No less than 17 affiliate groups have been identified as paying for access to the offering. ...

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 ...

CrowdStrike is named a Leader in the 2024 Gartner® Magic Quadrant™ for Endpoint Protection Platforms for the fifth consecutive time, positioned highest on Ability to Execute and furthest to the right on Completeness of Vision.

A South Korea-aligned cyber espionage has been linked to the zero-day exploitation of a now-patched critical remote code execution flaw in Kingsoft WPS Office to deploy a bespoke backdoor dubbed SpyGlace. The activity has been attributed to a threat actor dubbed APT-C-60 , according to cybersecurity firms ESET and DBAPPSecurity. The attacks have been found to infect Chinese and East Asian users with malware. The security flaw in question is CVE-2024-7262 (CVSS score: 9.3), which stems from a lack of proper validation of user-provided file paths. This loophole essentially allows an adversary to upload an arbitrary Windows library and achieve remote code execution. The bug "allows code execution via hijacking the control flow of the WPS Office plugin component promecefpluginhost.exe," ESET said , adding it found another way to achieve the same effect. The second vulnerability is tracked as CVE-2024-7263 (CVSS score: 9.3). The attack conceived by APT-C-60 weaponizes the...

An installer for a tool likely used by the Russian Consular Department of the Ministry of Foreign Affairs (MID) has been backdoored to deliver a remote access trojan called  Konni RAT  (aka  UpDog ). The findings come from German cybersecurity company DCSO, which linked the activity as originating from the Democratic People's Republic of Korea (DPRK)-nexus actors targeting Russia. The Konni (aka Opal Sleet, Osmium, or  TA406 ) activity cluster has an established pattern of deploying Konni RAT against Russian entities, with the threat actor also linked to  attacks directed against MID  at least since October 2021. In November 2023, Fortinet FortiGuard Labs  revealed  the use of Russian-language Microsoft Word documents to deliver malware capable of harvesting sensitive information from compromised Windows hosts. DCSO said the packaging of Konni RAT within software installers is a technique  previously adopted  by the group in Octobe...

A new "post-exploitation tampering technique" can be abused by malicious actors to visually deceive a target into believing that their Apple iPhone is running in Lockdown Mode when it's actually not and carry out covert attacks. The novel method, detailed by Jamf Threat Labs in a  report  shared with The Hacker News, "shows that if a hacker has already infiltrated your device, they can cause Lockdown Mode to be 'bypassed' when you trigger its activation." In other words, the goal is to implement Fake Lockdown Mode on a device that's compromised by an attacker through other means, such as  unpatched security flaws  that can trigger execution of arbitrary code. Lockdown Mode , introduced by Apple last year with iOS 16, is an  enhanced security measure  that aims to safeguard high-risk individuals from sophisticated digital threats such as mercenary spyware by  minimizing the attack surface . What it doesn't do is prevent the execution of mali...

A hacking group that leveraged a recently disclosed security flaw in the WinRAR software as a zero-day has now been categorized as an entirely new advanced persistent threat (APT). Cybersecurity company NSFOCUS has described  DarkCasino  as an "economically motivated" actor that first came to light in 2021. "DarkCasino is an APT threat actor with strong technical and learning ability, who is good at integrating various popular APT attack technologies into its attack process," the company  said  in an analysis. "Attacks launched by the APT group DarkCasino are very frequent, demonstrating a strong desire to steal online property." DarkCasino was most recently linked to the zero-day exploitation of  CVE-2023-38831  (CVSS score: 7.8), a security flaw that can be weaponized to launch malicious payloads. In August 2023, Group-IB disclosed real-world attacks weaponizing the vulnerability and aimed at online trading forums at least since April 2023 to deli...

The suspected Pakistan-linked threat actor known as  Transparent Tribe  is using malicious Android apps mimicking YouTube to distribute the CapraRAT mobile remote access trojan (RAT), demonstrating the continued evolution of the activity. "CapraRAT is a highly invasive tool that gives the attacker control over much of the data on the Android devices that it infects," SentinelOne security researcher Alex Delamotte  said  in a Monday analysis. Transparent Tribe , also known as APT36, is known to  target Indian entities  for intelligence-gathering purposes, relying on an arsenal of tools capable of infiltrating Windows, Linux, and Android systems. A crucial component of its toolset is  CapraRAT , which has been propagated in the form of trojanized secure messaging and calling apps branded as MeetsApp and MeetUp. These weaponized apps are distributed using social engineering lures. The latest set of Android package (APK) files discovered by SentinelO...

Businesses operating in the Latin American (LATAM) region are the target of a new Windows-based banking trojan called  TOITOIN  since May 2023. "This sophisticated campaign employs a trojan that follows a multi-staged infection chain, utilizing specially crafted modules throughout each stage," Zscaler researchers Niraj Shivtarkar and Preet Kamal  said  in a report published last week. "These modules are custom designed to carry out malicious activities, such as injecting harmful code into remote processes, circumventing User Account Control via COM Elevation Moniker, and evading detection by Sandboxes through clever techniques like system reboots and parent process checks." The six-stage endeavor has all the hallmarks of a well-crafted attack sequence, beginning with a phishing email containing an embedded link that points to a ZIP archive hosted on an Amazon EC2 instance to evade domain-based detections. The email messages leverage an invoice-themed lure to t...

Trojanized versions of legitimate applications are being used to deploy evasive cryptocurrency mining malware on macOS systems. Jamf Threat Labs, which made the discovery, said the XMRig coin miner was executed by means of an unauthorized modification in Final Cut Pro, a video editing software from Apple. "This malware makes use of the Invisible Internet Project (i2p) [...] to download malicious components and send mined currency to the attacker's wallet," Jamf researchers Matt Benyo, Ferdous Saljooki, and Jaron Bradley  said  in a report shared with The Hacker News. An earlier iteration of the campaign was  documented  exactly a year ago by Trend Micro, which pointed out the malware's use of i2p to conceal network traffic and speculated that it may have been delivered as a DMG file for Adobe Photoshop CC 2019.  The Apple device management company said the source of the cryptojacking apps can be traced to Pirate Bay, with the earliest uploads dating all th...

A new variant of the macOS malware tracked as UpdateAgent has been spotted in the wild, indicating ongoing attempts on the part of its authors to upgrade its functionalities. "Perhaps one of the most identifiable features of the malware is that it relies on the AWS infrastructure to host its various payloads and perform its infection status updates to the server," researchers from Jamf Threat Labs  said  in a report. UpdateAgent, first detected in late 2020, has since  evolved  into a malware dropper, facilitating the distribution of second-stage payloads such as adware while also bypassing macOS  Gatekeeper  protections. The newly discovered Swift-based dropper masquerades as Mach-O binaries named " PDFCreator " and " ActiveDirectory " that, upon execution, establish a connection to a remote server and retrieve a bash script to be executed. "The primary difference [between the two executables] is that it reaches out to a different URL from wh...

Cybersecurity researchers have shed light on an actively maintained remote access trojan called DCRat (aka DarkCrystal RAT) that's offered on sale for "dirt cheap" prices, making it accessible to professional cybercriminal groups and novice actors alike. "Unlike the well-funded, massive Russian threat groups crafting custom malware [...], this remote access Trojan (RAT) appears to be the work of a lone actor, offering a surprisingly effective homemade tool for opening backdoors on a budget," BlackBerry researchers said in a report shared with The Hacker News. "In fact, this threat actor's commercial RAT sells at a fraction of the standard price such tools command on Russian underground forums." Written in .NET by an individual codenamed "boldenis44" and "crystalcoder," DCRat is a full-featured backdoor whose functionalities can be further augmented by third-party plugins developed by affiliates using a dedicated integrated ...

An ongoing search engine optimization (SEO) poisoning attack campaign has been observed abusing trust in legitimate software utilities to trick users into downloading BATLOADER malware on compromised machines. "The threat actor used 'free productivity apps installation' or 'free software development tools installation' themes as SEO keywords to lure victims to a compromised website and to download a malicious installer," researchers from Mandiant  said  in a report published this week. In  SEO poisoning  attacks, adversaries artificially increase the search engine ranking of websites (genuine or otherwise) hosting their malware to make them show up on top of search results so that users searching for specific apps like TeamViewer, Visual Studio, and Zoom are infected with malware. The installer, while packing the legitimate software, is also bundled with the BATLOADER payload that's executed during the installation process. The malware then acts as a ...

At least 17 malware-laced packages have been discovered on the NPM package Registry, adding to a  recent barrage of malicious software  hosted and delivered through open-source software repositories such as PyPi and RubyGems. DevOps firm JFrog said the libraries, now taken down, were designed to grab Discord access tokens and  environment variables  from users' computers as well as gain full control over a victim's system. "The packages' payloads are varied, ranging from infostealers up to full remote access backdoors," researchers Andrey Polkovnychenko and Shachar Menashe said in a  report  published Wednesday. "Additionally, the packages have different infection tactics, including typosquatting,  dependency confusion  and trojan functionality." The list of packages is below - prerequests-xcode (version 1.0.4) discord-selfbot-v14 (version 12.0.3) discord-lofy (version 11.5.1) discordsystem (version 11.5.1) discord-vilao (version 1.0.0)...

Cybercriminals are now deploying remote access Trojans (RATs) under the guise of seemingly innocuous images hosted on infected websites, once again highlighting how threat actors quickly change tactics when their attack methods are discovered and exposed publicly. New research released by Cisco Talos reveals an active malware campaign targeting organizations in South Asia that utilize malicious Microsoft Office documents forged with macros to spread a RAT that goes by the name of  ObliqueRAT . First documented in  February 2020 , the malware has been linked to a threat actor tracked as  Transparent Tribe  (aka Operation C-Major, Mythic Leopard, or APT36), a highly prolific group allegedly of Pakistani origin known for its attacks against human rights activists in the country as well as military and government personnel in India. While the ObliqueRAT modus operandi previously overlapped with another Transparent Tribe campaign in December 2019 to disseminate Crims...

A framework notorious for delivering a banking Trojan has received a facelift to deploy a wider range of malware, including ransomware payloads. "The  Gootkit  malware family has been around more than half a decade – a mature Trojan with functionality centered around banking credential theft," Sophos researchers Gabor Szappanos and Andrew Brandt  said  in a write-up published today. "In recent years, almost as much effort has gone into improvement of its delivery method as has gone into the NodeJS-based malware itself." Dubbed "Gootloader," the expanded malware delivery system comes amid a surge in the number of infections targeting users in France, Germany, South Korea, and the U.S. First documented in 2014, Gootkit is a Javascript-based malware platform capable of carrying out an array of covert activities, including web injection, capturing keystrokes, taking screenshots, recording videos, as well as email and password theft. Over the years, the ...

Four months after security researchers uncovered a " Tetrade " of four Brazilian banking Trojans targeting financial institutions in Brazil, Latin America, and Europe, new findings show that the criminals behind the operation have expanded their tactics to infect mobile devices with spyware. According to Kaspersky's Global Research and Analysis Team (GReAT), the Brazil-based threat group Guildma has deployed " Ghimob ," an Android banking Trojan targeting financial apps from banks, fintech companies, exchanges, and cryptocurrencies in Brazil, Paraguay, Peru, Portugal, Germany, Angola, and Mozambique. "Ghimob is a full-fledged spy in your pocket: once infection is completed, the hacker can access the infected device remotely, completing the fraudulent transaction with the victim's smartphone, so as to avoid machine identification, security measures implemented by financial institutions and all their anti-fraud behavioral systems," the cybersecur...

A Windows-based remote access Trojan believed to be designed by Pakistani hacker groups to infiltrate computers and steal users' data has resurfaced after a two-year span with retooled capabilities to target Android and macOS devices. According to cybersecurity firm Kaspersky, the malware — dubbed " GravityRAT " — now masquerades as legitimate Android and macOS apps to capture device data, contact lists, e-mail addresses, and call and text logs and transmit them to an attacker-controlled server. First documented by the Indian Computer Emergency Response Team (CERT-In) in August 2017 and subsequently by  Cisco Talos  in April 2018, GravityRAT has been known to target Indian entities and organizations via malware-laced Microsoft Office Word documents at least since 2015. Noting that the threat actor developed at least four different versions of the espionage tool, Cisco said, "the developer was clever enough to keep this infrastructure safe, and not have it blackl...

The US-CERT has released a joint technical alert from the DHS and the FBI, warning about two newly identified malware being used by the prolific North Korean APT hacking group known as Hidden Cobra. Hidden Cobra, often known as Lazarus Group and Guardians of Peace, is believed to be backed by the North Korean government and known to launch attacks against media organizations, aerospace, financial and critical infrastructure sectors across the world. The group was even associated with the WannaCry ransomware menace that last year shut down hospitals and businesses worldwide. It is reportedly also linked to the 2014 Sony Pictures hack , as well as the SWIFT Banking attack in 2016. Now, the Department of Homeland Security (DHS) and the FBI have uncovered two new pieces of malware that Hidden Cobra has been using since at least 2009 to target companies working in the media, aerospace, financial, and critical infrastructure sectors across the world. The malware Hidden Cobra is...
