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

A North Korea-linked threat actor known for its cyber espionage operations has gradually expanded into financially-motivated attacks that involve the deployment of ransomware, setting it apart from other nation-state hacking groups linked to the country. Google-owned Mandiant is tracking the activity cluster under a new moniker APT45 , which overlaps with names such as Andariel, Nickel Hyatt, Onyx Sleet (formerly Plutonium), Silent Chollima, and Stonefly. "APT45 is a long-running, moderately sophisticated North Korean cyber operator that has carried out espionage campaigns as early as 2009," researchers Taylor Long, Jeff Johnson, Alice Revelli, Fred Plan, and Michael Barnhart said . "APT45 has been the most frequently observed targeting critical infrastructure." It's worth mentioning that APT45, along with APT38 (aka BlueNoroff), APT43 (aka Kimsuky), and Lazarus Group (aka TEMP.Hermit), are elements within North Korea's Reconnaissance General Bureau

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

As many as 165 customers of Snowflake are said to have had their information potentially exposed as part of an ongoing campaign designed to facilitate data theft and extortion, indicating the operation has broader implications than previously thought. Google-owned Mandiant, which is assisting the cloud data warehousing platform in its incident response efforts, is tracking the as-yet-unclassified activity cluster under the name UNC5537 , describing it as a financially motivated threat actor. "UNC5537 is systematically compromising Snowflake customer instances using stolen customer credentials, advertising victim data for sale on cybercrime forums, and attempting to extort many of the victims," the threat intelligence firm said on Monday. "UNC5537 has targeted hundreds of organizations worldwide, and frequently extorts victims for financial gain. UNC5537 operates under various aliases on Telegram channels and cybercrime forums." There is evidence to suggest tha

The WINELOADER backdoor used in recent cyber attacks targeting diplomatic entities with wine-tasting phishing lures has been attributed as the handiwork of a hacking group with links to Russia's Foreign Intelligence Service (SVR), which was responsible for  breaching SolarWinds and Microsoft . The findings come from Mandiant, which said  Midnight Blizzard  (aka APT29, BlueBravo, or Cozy Bear) used the malware to target German political parties with phishing emails bearing a logo from the Christian Democratic Union (CDU) around February 26, 2024. "This is the first time we have seen this APT29 cluster target political parties, indicating a possible area of emerging operational focus beyond the  typical   targeting  of  diplomatic missions ," researchers Luke Jenkins and Dan Black  said . WINELOADER was  first disclosed  by Zscaler ThreatLabz last month as part of a cyber espionage campaign that's believed to have been ongoing since at least July 2023. It attribute

A China-linked threat cluster leveraged security flaws in Connectwise ScreenConnect and F5 BIG-IP software to deliver custom malware capable of delivering additional backdoors on compromised Linux hosts as part of an "aggressive" campaign. Google-owned Mandiant is  tracking  the activity under its uncategorized moniker  UNC5174  (aka Uteus or Uetus), describing it as a "former member of Chinese hacktivist collectives that has since shown indications of acting as a contractor for China's Ministry of State Security (MSS) focused on executing access operations." The threat actor is believed to have orchestrated widespread attacks against Southeast Asian and U.S. research and education institutions, Hong Kong businesses, charities and non-governmental organizations (NGOs), and U.S. and U.K. government organizations between October and November 2023, and again in February 2024 using the ScreenConnect bug. Initial access to target environments is facilitated by t

Ivanti has disclosed details of a critical remote code execution flaw impacting Standalone Sentry, urging customers to apply the fixes immediately to stay protected against potential cyber threats. Tracked as  CVE-2023-41724 , the vulnerability carries a CVSS score of 9.6. "An unauthenticated threat actor can execute arbitrary commands on the underlying operating system of the appliance within the same physical or logical network," the company  said . The flaw impacts all supported versions 9.17.0, 9.18.0, and 9.19.0, as well as older versions. The company said it has made available a patch (versions 9.17.1, 9.18.1, and 9.19.1) that can be downloaded via the standard download portal. It credited Vincent Hutsebaut, Pierre Vivegnis, Jerome Nokin, Roberto Suggi Liverani and Antonin B. of NATO Cyber Security Centre for "their collaboration on this issue." Ivanti emphasized that it's not aware of any customers affected by CVE-2023-41724, and  added  that "

At least two different suspected China-linked cyber espionage clusters, tracked as  UNC5325  and  UNC3886 , have been attributed to the exploitation of security flaws in Ivanti Connect Secure VPN appliances. UNC5325 abused  CVE-2024-21893  to deliver a wide range of new malware called LITTLELAMB.WOOLTEA, PITSTOP, PITDOG, PITJET, and PITHOOK, as well as attempted to maintain persistent access to compromised appliances, Mandiant said. The Google-owned threat intelligence firm has assessed with moderate confidence that UNC5325 is associated with UNC3886 owing to source code overlaps in LITTLELAMB.WOOLTEA and PITHOOK with malware used by the latter. It's worth pointing out that  UNC3886  has a track record of leveraging zero-day flaws in Fortinet and VMware solutions to deploy a variety of implants like VIRTUALPITA, VIRTUALPIE, THINCRUST, and CASTLETAP. "UNC3886 has primarily targeted the defense industrial base, technology, and telecommunication organizations located in the U.S. and

A financially motivated threat actor known as  UNC4990  is leveraging weaponized USB devices as an initial infection vector to target organizations in Italy. Google-owned Mandiant said the attacks single out multiple industries, including health, transportation, construction, and logistics. "UNC4990 operations generally involve widespread USB infection followed by the deployment of the EMPTYSPACE downloader," the company  said  in a Tuesday report. "During these operations, the cluster relies on third-party websites such as GitHub, Vimeo, and Ars Technica to host encoded additional stages, which it downloads and decodes via PowerShell early in the execution chain." UNC4990, active since late 2020, is assessed to be operating out of Italy based on the extensive use of Italian infrastructure for command-and-control (C2) purposes. It's currently not known if UNC4990 functions only as an initial access facilitator for other actors. The end goal of the threat

The compromise of Mandiant's X (formerly Twitter) account last week was likely the result of a "brute-force password attack," attributing the hack to a drainer-as-a-service (DaaS) group. "Normally, [two-factor authentication] would have mitigated this, but due to some team transitions and a change in X's 2FA policy , we were not adequately protected," the threat intelligence firm  said  in a post shared on X. The attack, which took place on January 3, 2023,  enabled  the threat actor to take control of the company's X account and distribute links to a phishing page hosting a cryptocurrency drainer tracked as CLINKSINK. Drainers refer to malicious scripts and smart contracts that facilitate the theft of digital assets from the victim's wallets after they are tricked into approving the transactions. According to the Google-owned subsidiary, multiple threat actors are believed to have leveraged CLINKSINK since December 2023 to siphon funds and tok

American cybersecurity firm and Google Cloud subsidiary Mandiant had its X (formerly Twitter) account compromised for more than six hours by an unknown attacker to propagate a cryptocurrency scam. As of writing, the  account has been restored  on the social media platform. It's currently not clear how the account was breached. But the hacked Mandiant account was initially renamed to "@phantomsolw" to impersonate the Phantom crypto wallet service, according to  MalwareHunterTeam  and  vx-underground . Specifically, the scam posts from the account advertised an airdrop scam that urged users to click on a bogus link and earn free tokens, with follow-up messages asking Mandiant to "change password please" and "check bookmarks when you get account back." Mandiant, a leading threat intelligence firm, was  acquired by Google  in March 2022 for $5.4 billion. It is now part of Google Cloud. "The Mandiant Twitter account takeover could have happened

The notorious Russian hackers known as  Sandworm  targeted an electrical substation in Ukraine last year, causing a brief power outage in October 2022. The findings come from Google's Mandiant, which described the hack as a "multi-event cyber attack" leveraging a novel technique for impacting industrial control systems (ICS). "The actor first used OT-level living-off-the-land ( LotL ) techniques to likely trip the victim's substation circuit breakers, causing an unplanned power outage that coincided with mass missile strikes on critical infrastructure across Ukraine," the company  said . "Sandworm later conducted a second disruptive event by deploying a new variant of  CaddyWiper  in the victim's IT environment." The threat intelligence firm did not reveal the location of the targeted energy facility, the duration of the blackout, and the number of people who were impacted by the incident. The development marks Sandworm's  continuous

A group with links to Iran targeted transportation, logistics, and technology sectors in the Middle East, including Israel, in October 2023 amid a surge in Iranian cyber activity since the onset of the Israel-Hamas war. The attacks have been attributed by CrowdStrike to a threat actor it tracks under the name  Imperial Kitten , and which is also known as Crimson Sandstorm (previously Curium), TA456, Tortoiseshell, and Yellow Liderc. The latest findings from the company build on prior reports from  Mandiant ,  ClearSky , and  PwC , the latter of which also detailed instances of strategic web compromises (aka watering hole attacks) leading to the deployment of IMAPLoader on infected systems. "The adversary, active since at least 2017, likely fulfills Iranian strategic intelligence requirements associated with IRGC operations," CrowdStrike  said  in a technical report. "Its activity is characterized by its use of social engineering, particularly job recruitment-themed content, to deli

A financially motivated threat actor has been outed as an initial access broker (IAB) that sells access to compromised organizations for other adversaries to conduct follow-on attacks such as ransomware. SecureWorks Counter Threat Unit (CTU) has dubbed the e-crime group  Gold Melody , which is also known by the names Prophet Spider (CrowdStrike) and UNC961 (Mandiant). "This financially motivated group has been active since at least 2017, compromising organizations by exploiting vulnerabilities in unpatched internet-facing servers," the cybersecurity company  said . "The victimology suggests opportunistic attacks for financial gain rather than a targeted campaign conducted by a state-sponsored threat group for espionage, destruction, or disruption." Gold Melody has been  previously   linked  to  attacks  exploiting security flaws in JBoss Messaging (CVE-2017-7504), Citrix ADC (CVE-2019-19781), Oracle WebLogic (CVE-2020-14750 and CVE-2020-14882), GitLab (CVE-20

The financially motivated threat actor known as  UNC3944  is pivoting to ransomware deployment as part of an expansion to its monetization strategies, Mandiant has revealed. "UNC3944 has demonstrated a stronger focus on stealing large amounts of sensitive data for extortion purposes and they appear to understand Western business practices, possibly due to the geographical composition of the group," the threat intelligence firm  said . "UNC3944 has also consistently relied on publicly available tools and legitimate software in combination with malware available for purchase on underground forums." The group, also known by the names 0ktapus, Scatter Swine, and Scattered Spider, has been active since early 2022, adopting phone-based social engineering and SMS-based phishing to obtain employees' valid credentials using bogus sign-in pages and infiltrate victim organizations, mirroring tactics adopted by another group called  LAPSUS$ . While the group originall

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday disclosed details of a "novel persistent backdoor" called  SUBMARINE  deployed by threat actors in connection with the hack on Barracuda Email Security Gateway (ESG) appliances. "SUBMARINE comprises multiple artifacts — including a SQL trigger, shell scripts, and a loaded library for a Linux daemon — that together enable execution with root privileges, persistence, command and control, and cleanup," the agency  said . The findings come from an analysis of malware samples obtained from an unnamed organization that had been compromised by threat actors exploiting a critical flaw in ESG devices,  CVE-2023-2868  (CVSS score: 9.8), which allows for remote command injection. Evidence gathered so far shows that the attackers behind the activity, a suspected China nexus-actor tracked by Mandiant as  UNC4841 , leveraged the flaw as a zero-day in October 2022 to gain initial access to victim envir

VMware has flagged that a recently patched critical command injection vulnerability in Aria Operations for Networks (formerly vRealize Network Insight) has come under active exploitation in the wild. The flaw, tracked as  CVE-2023-20887 , could  allow  a malicious actor with network access to the product to perform a command injection attack, resulting in remote code execution. It impacts VMware Aria Operations Networks versions 6.x, with fixes released in versions 6.2, 6.3, 6.4, 6.5.1, 6.6, 6.7, 6.8, 6.9, and 6.10 on June 7, 2023. Now according to an update shared by the virtualization services provider on June 20, 2023, the flaw has been weaponized in real-world attacks, although the exact specifics are unknown as yet. "VMware has confirmed that exploitation of CVE-2023-20887 has occurred in the wild," the company  noted . Data gathered by threat intelligence firm GreyNoise  shows  active exploitation of the flaw from two different IP addresses located in the Netherl

A new strain of malicious software that's engineered to penetrate and disrupt critical systems in industrial environments has been unearthed. Google-owned threat intelligence firm Mandiant dubbed the malware  COSMICENERGY , adding it was uploaded to the VirusTotal public malware scanning utility in December 2021 by a submitter in Russia. There is no evidence that it has been put to use in the wild. "The malware is designed to cause electric power disruption by interacting with IEC 60870-5-104 (IEC-104) devices, such as remote terminal units ( RTUs ), that are commonly leveraged in electric transmission and distribution operations in Europe, the Middle East, and Asia," the company  said . COSMICENERGY is the latest addition to  specialized   malware  like Stuxnet, Havex, Triton, IRONGATE, BlackEnergy2, Industroyer, and PIPEDREAM, which are capable of sabotaging critical systems and wreaking havoc. Mandiant said that there are circumstantial links that it may have bee
