GoldenJackal Target Embassies and Air-Gapped Systems Using Malware Toolsets

GoldenJackal Target Embassies and Air-Gapped Systems Using Malware Toolsets

Oct 08, 2024 Cyber Attack / Malware
A little-known threat actor tracked as GoldenJackal has been linked to a series of cyber attacks targeting embassies and governmental organizations with an aim to infiltrate air-gapped systems using two disparate bespoke toolsets. Victims included a South Asian embassy in Belarus and a European Union (E.U.) government organization, Slovak cybersecurity company ESET said. "The ultimate goal of GoldenJackal seems to be stealing confidential information, especially from high-profile machines that might not be connected to the internet," security researcher Matías Porolli noted in an exhaustive analysis. GoldenJackal first came to light in May 2023, when Russian security vendor Kaspersky detailed the threat cluster's attacks on government and diplomatic entities in the Middle East and South Asia. The adversary's origins stretch back to at least 2019. An important characteristic of the intrusions is the use of a worm named JackalWorm that's capable of infectin
North Korean Hackers Using New VeilShell Backdoor in Stealthy Cyber Attacks

North Korean Hackers Using New VeilShell Backdoor in Stealthy Cyber Attacks

Oct 03, 2024 Cyber Espionage / Threat Intelligence
Threat actors with ties to North Korea have been observed delivering a previously undocumented backdoor and remote access trojan (RAT) called VeilShell as part of a campaign targeting Cambodia and likely other Southeast Asian countries. The activity, dubbed SHROUDED#SLEEP by Securonix, is believed to be the handiwork of APT37 , which is also known as InkySquid, Reaper, RedEyes, Ricochet Chollima, Ruby Sleet, and ScarCruft. Active since at least 2012, the adversarial collective is assessed to be part of North Korea's Ministry of State Security (MSS). Like with other state-aligned groups, those affiliated with North Korea, including the Lazarus Group and Kimsuky, vary in their modus operandi and likely have ever-evolving objectives based on state interests. A key malware in its toolbox is RokRAT (aka Goldbackdoor), although the group has also developed custom tools to facilitate covert intelligence gathering. It's currently not known how the first stage payload, a ZIP arc
How to Get Going with CTEM When You Don't Know Where to Start

How to Get Going with CTEM When You Don't Know Where to Start

Oct 04, 2024Vulnerability Management / Security Posture
Continuous Threat Exposure Management (CTEM) is a strategic framework that helps organizations continuously assess and manage cyber risk. It breaks down the complex task of managing security threats into five distinct stages: Scoping, Discovery, Prioritization, Validation, and Mobilization. Each of these stages plays a crucial role in identifying, addressing, and mitigating vulnerabilities - before they can be exploited by attackers.  On paper, CTEM sounds great . But where the rubber meets the road – especially for CTEM neophytes - implementing CTEM can seem overwhelming. The process of putting CTEM principles into practice can look prohibitively complex at first. However, with the right tools and a clear understanding of each stage, CTEM can be an effective method for strengthening your organization's security posture.  That's why I've put together a step-by-step guide on which tools to use for which stage. Want to learn more? Read on… Stage 1: Scoping  When you're defin

N. Korean Hackers Deploy New KLogEXE and FPSpy Malware in Targeted Attacks

Sep 26, 2024 Cyber Attack / Malware
Threat actors with ties to North Korea have been observed leveraging two new malware strains dubbed KLogEXE and FPSpy. The activity has been attributed to an adversary tracked as Kimsuky , which is also known as APT43, ARCHIPELAGO, Black Banshee, Emerald Sleet (formerly Thallium), Sparkling Pisces, Springtail, and Velvet Chollima. "These samples enhance Sparkling Pisces' already extensive arsenal and demonstrate the group's continuous evolution and increasing capabilities," Palo Alto Networks Unit 42 researchers Daniel Frank and Lior Rochberger said . Active since at least 2012, the threat actor has been called the "king of spear-phishing" for its ability to trick victims into downloading malware by sending emails that make it seem like they are from trusted parties. Unit 42's analysis of Sparkling Pisces' infrastructure has uncovered two new portable executables referred to as KLogEXE and FPSpy. "These malware strains are known to be de

Iranian APT UNC1860 Linked to MOIS Facilitates Cyber Intrusions in Middle East

Sep 20, 2024 Malware / Cyber Threat
An Iranian advanced persistent threat (APT) threat actor likely affiliated with the Ministry of Intelligence and Security (MOIS) is now acting as an initial access facilitator that provides remote access to target networks. Google-owned Mandiant is tracking the activity cluster under the moniker UNC1860 , which it said shares similarities with intrusion sets tracked by Microsoft, Cisco Talos, and Check Point as Storm-0861 (formerly DEV-0861), ShroudedSnooper , and Scarred Manticore , respectively. "A key feature of UNC1860 is its collection of specialized tooling and passive backdoors that [...] supports several objectives, including its role as a probable initial access provider and its ability to gain persistent access to high-priority networks, such as those in the government and telecommunications space throughout the Middle East," the company said . The group first came to light in July 2022 in connection with destructive cyber attacks targeting Albania with a rans
New Cross-Platform Malware KTLVdoor Discovered in Attack on Chinese Trading Firm

New Cross-Platform Malware KTLVdoor Discovered in Attack on Chinese Trading Firm

Sep 05, 2024 Cyber Attack / Malware
The Chinese-speaking threat actor known as Earth Lusca has been observed using a new backdoor dubbed KTLVdoor as part of a cyber attack targeting an unnamed trading company based in China. The previously unreported malware is written in Golang, and thus is a cross-platform weapon capable of targeting both Microsoft Windows and Linux systems. "KTLVdoor is a highly obfuscated malware that masquerades as different system utilities, allowing attackers to carry out a variety of tasks including file manipulation, command execution, and remote port scanning," Trend Micro researchers Cedric Pernet and Jaromir Horejsi said in an analysis published Wednesday. Some of the tools KTLVdoor impersonates include sshd, Java, SQLite, bash, and edr-agent, among others, with the malware distributed in the form of dynamic-link library (.dll) or a shared object (.so). Perhaps the most unusual aspect of the activity cluster is the discovery of more than 50 command-and-control (C&C) s

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 Cyberattack Targets Chinese-Speaking Businesses with Cobalt Strike Payloads

New Cyberattack Targets Chinese-Speaking Businesses with Cobalt Strike Payloads

Aug 30, 2024 Cyber Espionage / Threat Intelligence
Chinese-speaking users are the target of a "highly organized and sophisticated attack" campaign that is likely leveraging phishing emails to infect Windows systems with Cobalt Strike payloads. "The attackers managed to move laterally, establish persistence and remain undetected within the systems for more than two weeks," Securonix researchers Den Iuzvyk and Tim Peck said in a new report. The covert campaign, codenamed SLOW#TEMPEST and not attributed to any known threat actor, commences with malicious ZIP files that, when unpacked, activates the infection chain, leading to the deployment of the post-exploitation toolkit on compromised systems. Present with the ZIP archive is a Windows shortcut (LNK) file that disguises itself as a Microsoft Word file, "违规远程控制软件人员名单.docx.lnk," which roughly translates to "List of people who violated the remote control software regulations." "Given the language used in the lure files, it's likely th

Chinese Volt Typhoon Exploits Versa Director Flaw, Targets U.S. and Global IT Sectors

Aug 27, 2024 Cyber Espionage / Network Security
The China-nexus cyber espionage group tracked as Volt Typhoon has been attributed with moderate confidence to the zero-day exploitation of a recently disclosed high-severity security flaw impacting Versa Director. The attacks targeted four U.S. victims and one non-U.S. victim in the Internet service provider (ISP), managed service provider (MSP) and information technology (IT) sectors as early as June 12, 2024, the Black Lotus Labs team at Lumen Technologies said in a technical report shared with The Hacker News. The campaign is believed to be ongoing against unpatched Versa Director systems. The security flaw in question is CVE-2024-39717 (CVSS score: 6.6), a file upload bug affecting Versa Director that was added to the Known Exploited Vulnerabilities (KEV) catalog last week by the U.S. Cybersecurity and Infrastructure Security Agency (CISA). "This vulnerability allowed potentially malicious files to be uploaded by users with Provider-Data-Center-Admin or Provider-Data-Ce
New Linux Malware 'sedexp' Hides Credit Card Skimmers Using Udev Rules

New Linux Malware 'sedexp' Hides Credit Card Skimmers Using Udev Rules

Aug 25, 2024 Financial Fraud / Cybercrime
Cybersecurity researchers have uncovered a new stealthy piece of Linux malware that leverages an unconventional technique to achieve persistence on infected systems and hide credit card skimmer code. The malware, attributed to a financially motivated threat actor, has been codenamed sedexp by Aon's Stroz Friedberg incident response services team. "This advanced threat, active since 2022, hides in plain sight while providing attackers with reverse shell capabilities and advanced concealment tactics," researchers Zachary Reichert, Daniel Stein, and Joshua Pivirotto said . It's not surprising that malicious actors are constantly improvising and refining their tradecraft, and have turned to novel techniques to evade detection. What makes sedexp noteworthy is its use of udev rules to maintain persistence. Udev, a replacement for the Device File System, offers a mechanism to identify devices based on their properties and configure rules to respond when there is a ch
Multi-Stage ValleyRAT Targets Chinese Users with Advanced Tactics

Multi-Stage ValleyRAT Targets Chinese Users with Advanced Tactics

Aug 16, 2024 Cyber Attack / Malware
Chinese-speaking users are the target of an ongoing campaign that distributes a malware known as ValleyRAT. "ValleyRAT is a multi-stage malware that utilizes diverse techniques to monitor and control its victims and deploy arbitrary plugins to cause further damage," Fortinet FortiGuard Labs researchers Eduardo Altares and Joie Salvio said . "Another noteworthy characteristic of this malware is its heavy usage of shellcode to execute its many components directly in memory, significantly reducing its file footprint in the victim's system." Details about the campaign first emerged in June 2024, when Zscaler ThreatLabz detailed attacks involving an updated version of the malware. Exactly how the latest iteration of ValleyRAT is distributed is currently not known, although previous campaigns have leveraged email messages containing URLs pointing to compressed executables. "Based on the filenames of the executables we found, they're likely using phis

New Cyber Threat Targets Azerbaijan and Israel Diplomats, Stealing Sensitive Data

Aug 15, 2024 Cyber Espionage / Data Theft
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 (&

EastWind Attack Deploys PlugY and GrewApacha Backdoors Using Booby-Trapped LNK Files

Aug 12, 2024 Cloud Security / Malware
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

Cyber Espionage Group XDSpy Targets Companies in Russia and Moldova

Jul 31, 2024 Cyber Espionage / Threat Intelligence
Companies in Russia and Moldova have been the target of a phishing campaign orchestrated by a little-known cyber espionage group known as XDSpy . The findings come from cybersecurity firm F.A.C.C.T., which said the infection chains lead to the deployment of a malware called DSDownloader. The activity was observed this month, it added. XDSpy is a threat actor of indeterminate origin that was first uncovered by the Belarusian Computer Emergency Response Team, CERT.BY, in February 2020. A subsequent analysis by ESET attributed the group to information-stealing attacks aimed at government agencies in Eastern Europe and the Balkans since 2011. Attack chains mounted by the adversary are known to leverage spear-phishing emails in order to infiltrate their targets with a main malware module known as XDDown that, in turn, drops additional plugins for gathering system information, enumerating C: drive, monitoring external drives, exfiltrating local files, and gathering passwords.
