Threat actors affiliated with North Korea have been observed leveraging LinkedIn as a way to target developers as part of a fake job recruiting operation. These attacks employ coding tests as a common initial infection vector, Google-owned Mandiant said in a new report about threats faced by the Web3 sector. "After an initial chat conversation, the attacker sent a ZIP file that contained COVERTCATCH malware disguised as a Python coding challenge," researchers Robert Wallace, Blas Kojusner, and Joseph Dobson said . The malware functions as a launchpad to compromise the target's macOS system by downloading a second-stage payload that establishes persistence via Launch Agents and Launch Daemons. It's worth pointing out that this is one of many activity clusters – namely Operation Dream Job , Contagious Interview , and others – undertaken by North Korean hacking groups that make use of job-related decoys to infect targets with malware. Recruiting-themed lures have

A recently disclosed security flaw in OSGeo GeoServer GeoTools has been exploited as part of multiple campaigns to deliver cryptocurrency miners, botnet malware such as Condi and JenX, and a known backdoor called SideWalk. The security vulnerability is a critical remote code execution bug (CVE-2024-36401, CVSS score: 9.8) that could allow malicious actors to take over susceptible instances. In mid-July, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) added it to its Known Exploited Vulnerabilities (KEV) catalog, based on evidence of active exploitation. The Shadowserver Foundation said it detected exploitation attempts against its honeypot sensors starting July 9, 2024. According to Fortinet FortiGuard Labs, the flaw has been observed being used to deliver GOREVERSE, a reverse proxy server designed to establish a connection with a command-and-control (C2) server for post-exploitation activity. These attacks are said to target IT service providers in India, tech

Account takeover attacks have emerged as one of the most persistent and damaging threats to cloud-based SaaS environments. Yet despite significant investments in traditional security measures, many organizations continue to struggle with preventing these attacks. A new report, " Why Account Takeover Attacks Still Succeed, and Why the Browser is Your Secret Weapon in Stopping Them " argues that the browser is the primary battleground where account takeover attacks unfold and, thus, where they should be neutralized. The report also provides effective guidance for mitigating the account takeover risk.  Below are some of the key points raised in the report: The Role of the Browser in Account Takeovers According to the report, the SaaS kill chain takes advantage of the fundamental components that are contained within the browser. For account takeover, these include: Executed Web Pages - Attackers can create phishing login pages or use MiTM over legitimate web pages to harve

Threat actors have long leveraged typosquatting as a means to trick unsuspecting users into visiting malicious websites or downloading booby-trapped software and packages. These attacks typically involve registering domains or packages with names slightly altered from their legitimate counterparts (e.g., goog1e.com vs. google.com). Adversaries targeting open-source repositories across platforms have relied on developers making typing errors to initiate software supply chain attacks through PyPI, npm, Maven Central, NuGet, RubyGems, and Crate. The latest findings from cloud security firm Orca show that even GitHub Actions , a continuous integration and continuous delivery ( CI/CD ) platform, is not immune from the threat. "If developers make a typo in their GitHub action that matches a typosquatter's action,, applications could be made to run malicious code without the developer even realizing," security researcher Ofir Yakobi said in a report shared with The H

Unnamed government entities in the Middle East and Malaysia are the target of a persistent cyber campaign orchestrated by a threat actor known as Tropic Trooper since June 2023. "Sighting this group's [Tactics, Techniques, and Procedures] in critical governmental entities in the Middle East, particularly those related to human rights studies, marks a new strategic move for them," Kaspersky security researcher Sherif Magdy said . The Russian cybersecurity vendor said it detected the activity in June 2024 upon discovering a new version of the China Chopper web Shell, a tool shared by many Chinese-speaking threat actors for remote access to compromised servers, on a public web server hosting an open-source content management system (CMS) called Umbraco. The attack chain is designed to deliver a malware implant named Crowdoor , a variant of the SparrowDoor backdoor documented by ESET back in September 2021. The efforts were ultimately unsuccessful. Tropic Trooper, also

Threat actors are likely employing a tool designated for red teaming exercises to serve malware, according to new findings from Cisco Talos. The program in question is a payload generation framework called MacroPack , which is used to generate Office documents, Visual Basic scripts, Windows shortcuts, and other formats for penetration testing and social engineering assessments. It was developed by French developer Emeric Nasi. The cybersecurity company said it found artifacts uploaded to VirusTotal from China, Pakistan, Russia, and the U.S. that were all generated by MacroPack and used to deliver various payloads such as Havoc, Brute Ratel , and a new variant of PhantomCore , a remote access trojan (RAT) attributed to a hacktivist group named Head Mare. "A common feature in all the malicious documents we dissected that caught our attention is the existence of four non-malicious VBA subroutines," Talos researcher Vanja Svajcer said . "These subroutines appeared

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

North Korean threat actors have leveraged a fake Windows video conferencing application impersonating FreeConference.com to backdoor developer systems as part of an ongoing financially-driven campaign dubbed Contagious Interview. The new attack wave, spotted by Singaporean company Group-IB in mid-August 2024, is yet another indication that the activity is also leveraging native installers for Windows and Apple macOS to deliver malware. Contagious Interview, also tracked as DEV#POPPER, is a malicious campaign orchestrated by a North Korean threat actor tracked by CrowdStrike under the moniker Famous Chollima. The attack chains begin with a fictitious job interview, tricking job seekers into downloading and running a Node.js project that contains the BeaverTail downloader malware, which in turn delivers InvisibleFerret, a cross-platform Python backdoor that's equipped with remote control, keylogging, and browser stealing capabilities. Some iterations of BeaverTail, which also

A new supply chain attack technique targeting the Python Package Index (PyPI) registry has been exploited in the wild in an attempt to infiltrate downstream organizations. It has been codenamed Revival Hijack by software supply chain security firm JFrog, which said the attack method could be used to hijack 22,000 existing PyPI packages and result in "hundreds of thousands" of malicious package downloads. These susceptible packages have more than 100,000 downloads or have been active for over six months. "This attack technique involves hijacking PyPI software packages by manipulating the option to re-register them once they're removed from PyPI's index by the original owner," JFrog security researchers Andrey Polkovnychenko and Brian Moussalli said in a report shared with The Hacker News. At its core, the attack hinges on the fact that Python packages published in the PyPI repository may get removed, making available the names of those deleted projects

A new malware campaign is spoofing Palo Alto Networks' GlobalProtect VPN software to deliver a variant of the WikiLoader (aka WailingCrab) loader by means of a search engine optimization (SEO) campaign. The malvertising activity, observed in June 2024, is a departure from previously observed tactics wherein the malware has been propagated via traditional phishing emails, Unit 42 researchers Mark Lim and Tom Marsden said . WikiLoader, first documented by Proofpoint in August 2023, has been attributed to a threat actor known as TA544, with the email attacks leveraging the malware to deploy Danabot and Ursnif. Then earlier this April, South Korean cybersecurity company AhnLab detailed an attack campaign that leveraged a trojanized version of a Notepad++ plugin as the distribution vector. That said, the loader for rent is suspected to be used by at least two initial access brokers (IABs), per Unit 42, stating the attack chains are characterized by tactics that allow it to e

A hacktivist group known as Head Mare has been linked to cyber attacks that exclusively target organizations located in Russia and Belarus. "Head Mare uses more up-to-date methods for obtaining initial access," Kaspersky said in a Monday analysis of the group's tactics and tools. "For instance, the attackers took advantage of the relatively recent CVE-2023-38831 vulnerability in WinRAR, which allows the attacker to execute arbitrary code on the system via a specially prepared archive. This approach allows the group to deliver and disguise the malicious payload more effectively." Head Mare, active since 2023, is one of the hacktivist groups attacking Russian organizations in the context of the Russo-Ukrainian conflict that began a year before. It also maintains a presence on X , where it has leaked sensitive information and internal documentation from victims. Targets of the group's attacks include governments, transportation, energy, manufacturing,

Mobile users in Brazil are the target of a new malware campaign that delivers a new Android banking trojan named Rocinante. "This malware family is capable of performing keylogging using the Accessibility Service, and is also able to steal PII from its victims using phishing screens posing as different banks," Dutch security company ThreatFabric said . "Finally, it can use all this exfiltrated information to perform device takeover (DTO) of the device, by leveraging the accessibility service privileges to achieve full remote access on the infected device." Some of the prominent targets of the malware include financial institutions such as Itaú Shop, Santander, with the phony apps masquerading as Bradesco Prime and Correios Celular, among others - Livelo Pontos (com.resgatelivelo.cash) Correios Recarga (com.correiosrecarga.android) Bradesco Prime (com.resgatelivelo.cash) Módulo de Segurança (com.viberotion1414.app) Source code analysis of the ma

Roblox developers are the target of a persistent campaign that seeks to compromise systems through bogus npm packages, once again underscoring how threat actors continue to exploit the trust in the open-source ecosystem to deliver malware. "By mimicking the popular 'noblox.js' library, attackers have published dozens of packages designed to steal sensitive data and compromise systems," Checkmarx researcher Yehuda Gelb said in a technical report. Roblox is an online game platform and game creation system with nearly 80 million daily active users , and thus makes for an attractive target for threat actors. It was launched in September 2006 for Windows, before debuting in other platforms, including iOS, Android, Xbox One, Meta Quest, and PlayStation 4. Details about the activity were first documented by ReversingLabs in August 2023 as part of a campaign that delivered a stealer called Luna Token Grabber, which it said was a "replay of an attack uncovered two

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

Cybersecurity researchers have unearthed new network infrastructure set up by Iranian threat actors to support activities linked to the recent targeting of U.S. political campaigns. Recorded Future's Insikt Group has linked the infrastructure to a hacking group it tracks as GreenCharlie, an Iran-nexus cyber threat group that overlaps with APT42, Charming Kitten, Damselfly, Mint Sandstorm (formerly Phosphorus), TA453, and Yellow Garuda. "The group's infrastructure is meticulously crafted, utilizing dynamic DNS (DDNS) providers like Dynu, DNSEXIT, and Vitalwerks to register domains used in phishing attacks," the cybersecurity company said . "These domains often employ deceptive themes related to cloud services, file sharing, and document visualization to lure targets into revealing sensitive information or downloading malicious files." Examples include terms like "cloud," "uptimezone," "doceditor," "joincloud,"

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. The

Threat actors with ties to North Korea have been observed publishing a set of malicious packages to the npm registry, indicating "coordinated and relentless" efforts to target developers with malware and steal cryptocurrency assets. The latest wave, which was observed between August 12 and 27, 2024, involved packages named temp-etherscan-api, ethersscan-api, telegram-con, helmet-validate, and qq-console. "Behaviors in this campaign lead us to believe that qq-console is attributable to the North Korean campaign known as 'Contagious Interview,'" software supply chain security firm Phylum said . Contagious Interview refers to an ongoing campaign that seeks to compromise software developers with information stealing malware as part of a purported job interview process that involves tricking them into downloading bogus npm packages or fake installers for video conferencing software such as MiroTalk hosted on decoy websites. The end goal of the attacks is to

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

A non-profit supporting Vietnamese human rights has been the target of a multi-year campaign designed to deliver a variety of malware on compromised hosts. Cybersecurity company Huntress attributed the activity to a threat cluster tracked as APT32, a Vietnamese-aligned hacking crew that's also known as APT-C-00, Canvas Cyclone (formerly Bismuth), Cobalt Kitty, and OceanLotus. The intrusion is believed to have been ongoing for at least four years. "This intrusion has a number of overlaps with known techniques used by the threat actor APT32/OceanLotus, and a known target demographic which aligns with APT32/OceanLotus targets," security researchers Jai Minton and Craig Sweeney said . OceanLotus , active since at least 2012, has a history of targeting company and government networks in East-Asian countries, particularly Vietnam, the Philippines, Laos, and Cambodia with the end goal of cyber espionage and intellectual property theft. Attack chains typically make use of

Cybersecurity researchers have flagged multiple in-the-wild exploit campaigns that leveraged now-patched flaws in Apple Safari and Google Chrome browsers to infect mobile users with information-stealing malware. "These campaigns delivered n-day exploits for which patches were available, but would still be effective against unpatched devices," Google Threat Analysis Group (TAG) researcher Clement Lecigne said in a report shared with The Hacker News. The activity, observed between November 2023 and July 2024, is notable for delivering the exploits by means of a watering hole attack on Mongolian government websites, cabinet.gov[.]mn and mfa.gov[.]mn. A watering hole attack, also called a strategic website compromise attack, is a form of cyber attack that targets groups of users or those within a particular industry by compromising websites that they commonly visit in order to serve them with malware and gain access to their systems. The intrusion set has been attributed wi
