The North Korea-aligned threat actor known as Kimsuky has been linked to a series of phishing attacks that involve sending email messages that originate from Russian sender addresses to ultimately conduct credential theft. "Phishing emails were sent mainly through email services in Japan and Korea until early September," South Korean cybersecurity company Genians said . "Then, from mid-September, some phishing emails disguised as if they were sent from Russia were observed." This entails the abuse of VK's Mail.ru email service, which supports five different alias domains, including mail.ru, internet.ru, bk.ru, inbox.ru, and list.ru. Genians said it has observed the Kimsuky actors leveraging all the aforementioned sender domains for phishing campaigns that masquerade as financial institutions and internet portals like Naver. Other phishing attacks have entailed sending messages that mimic Naver's MYBOX cloud storage service and aim to trick users into ...

The North Korea-linked threat actor known as Sapphire Sleet is estimated to have stolen more than $10 million worth of cryptocurrency as part of social engineering campaigns orchestrated over a six-month period. These findings come from Microsoft, which said that multiple threat activity clusters with ties to the country have been observed creating fake profiles on LinkedIn, posing as both recruiters and job seekers to generate illicit revenue for the sanction-hit nation. Sapphire Sleet, which is known to be active since at least 2020, overlaps with hacking groups tracked as APT38 and BlueNoroff. In November 2023, the tech giant revealed that the threat actor had established infrastructure that impersonated skills assessment portals to carry out its social engineering campaigns. One of the main methods adopted by the group for over a year is to pose as a venture capitalist, deceptively claiming an interest in a target user's company in order to set up an online meeting. Targ...

Are you using the cloud or thinking about transitioning? Undoubtedly, multi-cloud and hybrid environments offer numerous benefits for organizations. However, the cloud's flexibility, scalability, and efficiency come with significant risk — an expanded attack surface. The decentralization that comes with utilizing multi-cloud environments can also lead to limited visibility into user activity and poor access management.  Privileged accounts with access to your critical systems and sensitive data are among the most vulnerable elements in cloud setups. When mismanaged, these accounts open the doors to unauthorized access, potential malicious activity, and data breaches. That's why strong privileged access management (PAM) is indispensable. PAM plays an essential role in addressing the security challenges of complex infrastructures by enforcing strict access controls and managing the life cycle of privileged accounts. By employing PAM in hybrid and cloud environments, you're not...

Threat actors with ties to the Democratic People's Republic of Korea (DPRK) are impersonating U.S.-based software and technology consulting businesses in order to further their financial objectives as part of a broader information technology (IT) worker scheme. "Front companies, often based in China, Russia, Southeast Asia, and Africa, play a key role in masking the workers' true origins and managing payments," SentinelOne security researchers Tom Hegel and Dakota Cary said in a report shared with The Hacker News. North Korea's network of IT workers, both in an individual capacity and under the cover of front companies, is seen as a technique to evade international sanctions imposed on the country and generate illicit revenues. The global campaign, which is also tracked as Wagemole by Palo Alto Networks Unit 42, entails using forged identities to obtain employment at various companies in the U.S. and elsewhere, and send back a huge portion of their wages bac...

Threat actors have been found leveraging a new technique that abuses extended attributes for macOS files to smuggle a new malware called RustyAttr . The Singaporean cybersecurity company has attributed the novel activity with moderate confidence to the infamous North Korea-linked Lazarus Group, citing infrastructure and tactical overlaps observed in connection with prior campaigns, including RustBucket .  Extended attributes refer to additional metadata associated with files and directories that can be extracted using a dedicated command called xattr . They are often used to store information that goes beyond the standard attributes, such as file size, timestamps, and permissions. The malicious applications discovered by Group-IB are built using Tauri , a cross-platform desktop application framework, and signed with a leaked certificate that has since been revoked by Apple. They include an extended attribute that's configured to fetch and run a shell script. The execution of...

Threat actors with ties to the Democratic People's Republic of Korea (DPRK aka North Korea) have been found embedding malware within Flutter applications, marking the first time this tactic has been adopted by the adversary to infect Apple macOS devices. Jamf Threat Labs, which made the discovery based on artifacts uploaded to the VirusTotal platform earlier this month, said the Flutter-built applications are part of a broader activity that includes malware written in Golang and Python. It's currently not known how these samples are distributed to victims, and if it has been used against any targets, or if the attackers are switching to a new delivery method. That said, North Korean threat actors are known to engage in extensive social engineering efforts targeting employees of cryptocurrency and decentralized finance businesses. "We suspect these specific examples are testing," Jaron Bradley, director at Jamf Threat Labs, told The Hacker News. "It's p...

A threat actor with ties to the Democratic People's Republic of Korea (DPRK) has been observed targeting cryptocurrency-related businesses with a multi-stage malware capable of infecting Apple macOS devices . Cybersecurity company SentinelOne, which dubbed the campaign Hidden Risk , attributed it with high confidence to BlueNoroff, which has been previously linked to malware families such as RustBucket , KANDYKORN , ObjCShellz , RustDoor (aka Thiefbucket ), and TodoSwift . The activity "uses emails propagating fake news about cryptocurrency trends to infect targets via a malicious application disguised as a PDF file," researchers Raffaele Sabato, Phil Stokes, and Tom Hegel said in a report shared with The Hacker News. "The campaign likely began as early as July 2024 and uses email and PDF lures with fake news headlines or stories about crypto-related topics." As revealed by the U.S. Federal Bureau of Investigation (FBI) in a September 2024 advisory, the...

Three malicious packages published to the npm registry in September 2024 have been found to contain a known malware called BeaverTail, a JavaScript downloader and information stealer linked to an ongoing North Korean campaign tracked as Contagious Interview. The Datadog Security Research team is monitoring the activity under the name Tenacious Pungsan , which is also known by the monikers CL-STA-0240 and Famous Chollima. The names of the malicious packages, which are no longer available for download from the package registry, are listed below - passports-js, a backdoored copy of the passport (118 downloads) bcrypts-js, a backdoored copy of bcryptjs (81 downloads) blockscan-api, a backdoored copy of etherscan-api (124 downloads) Contagious Interview refers to a yearlong-campaign undertaken by the Democratic People's Republic of Korea (DPRK) that involves tricking developers into downloading malicious packages or seemingly innocuous video conferencing applications as part...

North Korean information technology (IT) workers who obtain employment under false identities in Western companies are not only stealing intellectual property, but are also stepping up by demanding ransoms in order to not leak it, marking a new twist to their financially motivated attacks. "In some instances, fraudulent workers demanded ransom payments from their former employers after gaining insider access, a tactic not observed in earlier schemes," Secureworks Counter Threat Unit (CTU) said in an analysis published this week. "In one case, a contractor exfiltrated proprietary data almost immediately after starting employment in mid-2024." The activity, the cybersecurity company added, shares similarities with a threat group it tracks as Nickel Tapestry, which is also known as Famous Chollima and UNC5267 . The fraudulent IT worker scheme, orchestrated with the intent to advance North Korea's strategic and financial interests, refers to an insider threat...

Threat actors with ties to North Korea have been observed targeting job seekers in the tech industry to deliver updated versions of known malware families tracked as BeaverTail and InvisibleFerret. The activity cluster, tracked as CL-STA-0240, is part of a campaign dubbed Contagious Interview that Palo Alto Networks Unit 42 first disclosed in November 2023. "The threat actor behind CL-STA-0240 contacts software developers through job search platforms by posing as a prospective employer," Unit 42 said in a new report. "The attackers invite the victim to participate in an online interview, where the threat actor attempts to convince the victim to download and install malware." The first stage of infection involves the BeaverTail downloader and information stealer that's designed for targeting both Windows and Apple macOS platforms. The malware acts as a conduit for the Python-based InvisibleFerret backdoor. There is evidence to suggest that the activity ...

Three different organizations in the U.S. were targeted in August 2024 by a North Korean state-sponsored threat actor called Andariel as part of a likely financially motivated attack. "While the attackers didn't succeed in deploying ransomware on the networks of any of the organizations affected, it is likely that the attacks were financially motivated," Symantec, part of Broadcom, said in a report shared with The Hacker News. Andariel is a threat actor that's assessed to be a sub-cluster within the infamous Lazarus Group. It's also tracked as APT45, DarkSeoul, Nickel Hyatt, Onyx Sleet (formerly Plutonium), Operation Troy, Silent Chollima, and Stonefly. It's been active since at least 2009. An element within North Korea's Reconnaissance General Bureau (RGB), the hacking crew has a track record of deploying ransomware strains such as SHATTEREDGLASS and Maui , while also developing an arsenal of custom backdoors like Dtrack (aka Valefor and Preft), ...

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...

A North Korea-linked cyber-espionage group has been observed leveraging job-themed phishing lures to target prospective victims in energy and aerospace verticals and infect them with a previously undocumented backdoor dubbed MISTPEN. The activity cluster is being tracked by Google-owned Mandiant under the moniker UNC2970 , which it said overlaps with a threat group known as TEMP.Hermit , which is also broadly called Lazarus Group or Diamond Sleet (formerly Zinc). The threat actor has a history of targeting government, defense, telecommunications, and financial institutions worldwide since at least 2013 to collect strategic intelligence that furthers North Korean interests. It's affiliated with the Reconnaissance General Bureau (RGB). The threat intelligence firm said it has observed UNC2970 singling out various entities located in the U.S., the U.K., the Netherlands, Cyprus, Sweden, Germany, Singapore, Hong Kong, and Australia. "UNC2970 targets victims under the guise o...

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 ...

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 recently patched security flaw in Google Chrome and other Chromium web browsers was exploited as a zero-day by North Korean actors in a campaign designed to deliver the FudModule rootkit. The development is indicative of the persistent efforts made by the nation-state adversary, which has made a habit of incorporating rafts of Windows zero-day exploits into its arsenal in recent months. Microsoft, which detected the activity on August 19, 2024, attributed it to a threat actor it tracks as Citrine Sleet (formerly DEV-0139 and DEV-1222), which is also known as AppleJeus, Labyrinth Chollima, Nickel Academy, and UNC4736 . It's assessed to be a sub-cluster within the Lazarus Group (aka Diamond Sleet and Hidden Cobra). It's worth mentioning that the use of the AppleJeus malware has also been previously attributed by Kaspersky to another Lazarus subgroup called BlueNoroff (aka APT38, Nickel Gladstone, and Stardust Chollima), indicative of the infrastructure and toolset sharin...

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...
