Cyberattackers Exploit Google Sheets for Malware Control in Likely Espionage Campaign

Aug 30, 2024 Malware / Threat Intelligence
Cybersecurity researchers have uncovered a novel malware campaign that leverages Google Sheets as a command-and-control (C2) mechanism. The activity, detected by Proofpoint starting August 5, 2024, impersonates tax authorities from governments in Europe, Asia, and the U.S., with the goal of targeting over 70 organizations worldwide by means of a bespoke tool called Voldemort that's equipped to gather information and deliver additional payloads. Targeted sectors include insurance, aerospace, transportation, academia, finance, technology, industrial, healthcare, automotive, hospitality, energy, government, media, manufacturing, telecom, and social benefit organizations.  The suspected cyber espionage campaign has not been attributed to a specific named threat actor. As many as 20,000 email messages have been sent as part of the attacks. These emails claim to be from tax authorities in the U.S., the U.K., France, Germany, Italy, India, and Japan, alerting recipients about chan

New Malware Masquerades as Palo Alto VPN Targeting Middle East Users

Aug 30, 2024 Malware / Network Security
Cybersecurity researchers have disclosed a new campaign that potentially targets users in the Middle East through malware that disguises itself as Palo Alto Networks GlobalProtect virtual private network (VPN) tool. "The malware can execute remote PowerShell commands, download and exfiltrate files, encrypt communications, and bypass sandbox solutions, representing a significant threat to targeted organizations," Trend Micro researcher Mohamed Fahmy said in a technical report. The sophisticated malware sample has been observed employing a two-stage process and involves setting up connections to command-and-control (C2) infrastructure that purports to be a company VPN portal, allowing the threat actors to operate freely without tripping any alarms. The initial intrusion vector for the campaign is currently unknown, although it's suspected to involve the use of phishing techniques to deceive users into thinking that they are installing the GlobalProtect agent.

Chinese Hackers Target Japanese Firms with LODEINFO and NOOPDOOR Malware

Jul 31, 2024 Cyber Attack / Threat Intelligence
Japanese organizations are the target of a Chinese nation-state threat actor that leverages malware families like LODEINFO and NOOPDOOR to harvest sensitive information from compromised hosts while stealthily remaining under the radar in some cases for a time period ranging from two to three years. Israeli cybersecurity company Cybereason is tracking the campaign under the name Cuckoo Spear , attributing it as related to a known intrusion set dubbed APT10, which is also known as Bronze Riverside, ChessMaster, Cicada, Cloudhopper, MenuPass, MirrorFace, Purple Typhoon (formerly Potassium), and Stone Panda. "The actors behind NOOPDOOR not only utilized LODEINFO during the campaign, but also utilized the new backdoor to exfiltrate data from compromised enterprise networks," it said . The findings come weeks after JPCERT/CC warned of cyber attacks mounted by the threat actor targeting Japanese entities using the two malware strains. Earlier this January, ITOCHU Cyber & I

GitHub Token Leak Exposes Python's Core Repositories to Potential Attacks

GitHub Token Leak Exposes Python's Core Repositories to Potential Attacks

Jul 15, 2024 Supply Chain Attack / Cyber Threat
Cybersecurity researchers said they discovered an accidentally leaked GitHub token that could have granted elevated access to the GitHub repositories of the Python language, Python Package Index (PyPI), and the Python Software Foundation (PSF). JFrog, which found the GitHub Personal Access Token, said the secret was leaked in a public Docker container hosted on Docker Hub. "This case was exceptional because it is difficult to overestimate the potential consequences if it had fallen into the wrong hands – one could supposedly inject malicious code into PyPI packages (imagine replacing all Python packages with malicious ones), and even to the Python language itself," the software supply chain security company said . An attacker could have hypothetically weaponized their admin access to orchestrate a large-scale supply chain attack by poisoning the source code associated with the core of the Python programming language, or the PyPI package manager. JFrog noted that the aut

New APT Group "CloudSorcerer" Targets Russian Government Entities

Jul 08, 2024 Cyber Espionage / Cloud Security
A previously undocumented advanced persistent threat (APT) group dubbed CloudSorcerer has been observed targeting Russian government entities by leveraging cloud services for command-and-control (C2) and data exfiltration. Cybersecurity firm Kaspersky, which discovered the activity in May 2024, said the tradecraft adopted by the threat actor bears similarities with that of CloudWizard , but pointed out the differences in the malware source code. The attacks wield an innovative data-gathering program and a slew of evasion tactics for covering its tracks. "It's a sophisticated cyber espionage tool used for stealth monitoring, data collection, and exfiltration via Microsoft Graph, Yandex Cloud, and Dropbox cloud infrastructure," the Russian security vendor said . "The malware leverages cloud resources as its command and control (C2) servers, accessing them through APIs using authentication tokens. Additionally, CloudSorcerer uses GitHub as its initial C2 server.&q

New Rust-based Fickle Malware Uses PowerShell for UAC Bypass and Data Exfiltration

Jun 20, 2024 Threat Intelligence / Cybercrime
A new Rust-based information stealer malware called Fickle Stealer has been observed being delivered via multiple attack chains with the goal of harvesting sensitive information from compromised hosts. Fortinet FortiGuard Labs said it's aware of four different distribution methods -- namely VBA dropper, VBA downloader, link downloader, and executable downloader -- with some of them using a PowerShell script to bypass User Account Control (UAC) and execute Fickle Stealer. The PowerShell script ("bypass.ps1" or "u.ps1") is also designed to periodically send information about the victim, including country, city, IP address, operating system version, computer name, and username to a Telegram bot controlled by the attacker. The stealer payload, which is protected using a packer, runs a series of anti-analysis checks to determine if it's running in a sandbox or a virtual machine environment, following which it beacons out to a remote server to exfiltrate da

Malware Delivery via Cloud Services Exploits Unicode Trick to Deceive Users

May 21, 2024 Cloud Security / Data Security
A new attack campaign dubbed  CLOUD#REVERSER  has been observed leveraging legitimate cloud storage services like Google Drive and Dropbox to stage malicious payloads. "The VBScript and PowerShell scripts in the CLOUD#REVERSER inherently involves command-and-control-like activities by using Google Drive and Dropbox as staging platforms to manage file uploads and downloads," Securonix researchers Den Iuzvyk, Tim Peck, and Oleg Kolesnikov  said  in a report shared with The Hacker News. "The scripts are designed to fetch files that match specific patterns, suggesting they are waiting for commands or scripts placed in Google Drive or Dropbox." The starting point of the attack chain is a phishing email bearing a ZIP archive file, which contains an executable that masquerades as a Microsoft Excel file. In an interesting twist, the filename makes use of the hidden right-to-left override ( RLO ) Unicode character (U+202E) to reverse the order of the characters that co

APT42 Hackers Pose as Journalists to Harvest Credentials and Access Cloud Data

May 07, 2024 Cyber Espionage / Malware
The Iranian state-backed hacking outfit called  APT42  is making use of enhanced social engineering schemes to infiltrate target networks and cloud environments. Targets of the attack include Western and Middle Eastern NGOs, media organizations, academia, legal services and activists, Google Cloud subsidiary Mandiant said in a report published last week. "APT42 was observed  posing as journalists  and event organizers to build trust with their victims through ongoing correspondence, and to deliver invitations to conferences or legitimate documents," the company  said . "These social engineering schemes enabled APT42 to harvest credentials and use them to gain initial access to cloud environments. Subsequently, the threat actor covertly exfiltrated data of strategic interest to Iran, while relying on built-in features and open-source tools to avoid detection." APT42 (aka Damselfly and UNC788),  first documented  by the company in September 2022, is an Iranian st

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

Linux Version of DinodasRAT Spotted in Cyber Attacks Across Several Countries

Mar 28, 2024 Linux / Network Security
A Linux version of a multi-platform backdoor called  DinodasRAT  has been detected in the wild targeting China, Taiwan, Turkey, and Uzbekistan,  new findings  from Kaspersky reveal. DinodasRAT, also known as XDealer, is a C++-based malware that offers the ability to harvest a wide range of sensitive data from compromised hosts. In October 2023, Slovak cybersecurity firm ESET  revealed  that a governmental entity in Guyana had been targeted as part of a cyber espionage campaign dubbed Operation Jacana to deploy the Windows version of the implant. Then last week, Trend Micro  detailed  a threat activity cluster it tracks as Earth Krahang and which has shifted to using DinodasRAT since 2023 in its attacks aimed at several government entities worldwide. The use of DinodasRAT has been attributed to various China-nexus threat actors, including  LuoYu , once again reflecting the tool sharing prevalent among hacking crews identified as acting on behalf of the country.

Russia Hackers Using TinyTurla-NG to Breach European NGO's Systems

Mar 21, 2024 Threat Intelligence / Malware
The Russia-linked threat actor known as Turla infected several systems belonging to an unnamed European non-governmental organization (NGO) in order to deploy a backdoor called TinyTurla-NG (TTNG) . "The attackers compromised the first system, established persistence and added exclusions to antivirus products running on these endpoints as part of their preliminary post-compromise actions," Cisco Talos  said  in a new report published today. "Turla then opened additional channels of communication via Chisel for data exfiltration and to pivot to additional accessible systems in the network." There is evidence indicating that the infected systems were breached as early as October 2023, with Chisel deployed in December 2023 and data exfiltration taking place via the tool a month later, around January 12, 2024. TinyTurla-NG was  first documented  by the cybersecurity company last month after it was found to be used in connection with a cyber attack targeting a Poli

Hackers Using Cracked Software on GitHub to Spread RisePro Info Stealer

Mar 16, 2024 Malware / Cybercrime
Cybersecurity researchers have found a number of GitHub repositories offering cracked software that are used to deliver an information stealer called RisePro. The campaign, codenamed  gitgub , includes 17 repositories associated with 11 different accounts, according to G DATA. The repositories in question have since been taken down by the Microsoft-owned subsidiary. "The repositories look similar, featuring a README.md file with the promise of free cracked software," the German cybersecurity company  said . "Green and red circles are commonly used on Github to display the status of automatic builds. Gitgub threat actors added four green Unicode circles to their README.md that pretend to display a status alongside a current date and provide a sense of legitimacy and recency." The list of repositories is as follows, with each of them pointing to a download link ("digitalxnetwork[.]com") containing a RAR archive file - andreastanaj/AVAST andreastanaj
