Threat actors linked to the Black Basta ransomware may have exploited a recently disclosed privilege escalation flaw in the Microsoft Windows Error Reporting Service as a zero-day, according to new findings from Symantec. The security flaw in question is CVE-2024-26169 (CVSS score: 7.8), an elevation of privilege bug in the Windows Error Reporting Service that could be exploited to achieve SYSTEM privileges. It was patched by Microsoft in March 2024. "Analysis of an exploit tool deployed in recent attacks revealed evidence that it could have been compiled prior to patching, meaning at least one group may have been exploiting the vulnerability as a zero-day," the Symantec Threat Hunter Team, part of Broadcom, said in a report shared with The Hacker News. The financially motivated threat cluster is being tracked by the company under the name Cardinal. It's also monitored by the cybersecurity community under the names Storm-1811 and UNC4393 . It's known to mon

The U.S. Federal Bureau of Investigation (FBI) has disclosed that it's in possession of more than 7,000 decryption keys associated with the LockBit ransomware operation to help victims get their data back at no cost. "We are reaching out to known LockBit victims and encouraging anyone who suspects they were a victim to visit our Internet Crime Complaint Center at ic3.gov," FBI Cyber Division Assistant Director Bryan Vorndran said in a keynote address at the 2024 Boston Conference on Cyber Security (BCCS). LockBit, which was once a prolific ransomware gang, has been linked to over 2,400 attacks globally, with no less than 1,800 impacting entities in the U.S. Earlier this February, an international law enforcement operation dubbed Cronos led by the U.K. National Crime Agency (NCA) dismantled its online infrastructure. Last month, a 31-year-old Russian national named Dmitry Yuryevich Khoroshev was outed by authorities as the group's administrator and developer, a

Learn about critical threats that can impact your organization and the bad actors behind them from Cybersixgill's threat experts. Each story shines a light on underground activities, the threat actors involved, and why you should care, along with what you can do to mitigate risk.  In an increasingly interconnected world, supply chain attacks have emerged as a formidable threat, compromising not just individual organizations but the broader digital ecosystem. The web of interdependencies among businesses, especially for software and IT vendors, provides fertile ground for cybercriminals to exploit vulnerabilities. By targeting one weak link in the supply chain, threat actors can gain unauthorized access to sensitive information and can conduct malicious activities with severe consequences on multiple organizations, from data breaches and financial losses to widespread disruption and reputational damage. Understanding the nature, impact, and mitigation strategies of supply chain att

An analysis of a nascent ransomware strain called RansomHub has revealed it to be an updated and rebranded version of Knight ransomware, itself an evolution of another ransomware known as Cyclops. Knight (aka Cyclops 2.0) ransomware first arrived in May 2023, employing double extortion tactics to steal and encrypt victims' data for financial gain. It's operational across multiple platforms, including Windows, Linux, macOS, ESXi, and Android. Advertised and sold on the RAMP cybercrime forum, attacks involving the ransomware have been found to leverage phishing and spear-phishing campaigns as a distribution vector in the form of malicious attachments. The ransomware-as-a-service (RaaS) operation has since shut down as of late February 2024, when its source code was put up for sale , raising the possibility that it may have changed hands to a different actor, who subsequently decided to update and relaunch it under the RansomHub brand. RansomHub, which posted its first v

Law enforcement authorities behind Operation Endgame are seeking information related to an individual who goes by the name Odd and is allegedly the mastermind behind the Emotet malware.  Odd is also said to go by the nicknames Aron, C700, Cbd748, Ivanov Odd, Mors, Morse, and Veron over the past few years, according to a video released by the agencies. "Who is he working with? What is his current product?," the video continues, suggesting that he is likely not acting alone and may be collaborating with others on malware other than Emotet. The threat actor(s) behind Emotet has been tracked by the cybersecurity community under the monikers Gold Crestwood, Mealybug, Mummy Spider, and TA542. Originally conceived as a banking trojan, it evolved into a broader-purpose tool capable of delivering other payloads, along the lines of malware such as TrickBot, IcedID, QakBot, and others. It re-emerged in late 2021, albeit as part of low-volume campaigns, following a law enforceme

Europol on Thursday said it shut down the infrastructure associated with several malware loader operations such as IcedID, SystemBC, PikaBot, SmokeLoader, Bumblebee, and TrickBot as part of a coordinated law enforcement effort codenamed Operation Endgame . "The actions focused on disrupting criminal services through arresting High Value Targets, taking down the criminal infrastructures and freezing illegal proceeds," Europol said in a statement. "The malware [...] facilitated attacks with ransomware and other malicious software." The action, which took place between May 27 and May 29, has resulted in the dismantling of over 100 servers worldwide and the arrest of four people, one in Armenia three in Ukraine , following searches across 16 locations in Armenia, the Netherlands, Portugal, and Ukraine. The servers, according to Europol, were located in Bulgaria, Canada, Germany, Lithuania, the Netherlands, Romania, Switzerland, Ukraine, the United Kingdom, and the

Ransomware attacks targeting VMware ESXi infrastructure follow an established pattern regardless of the file-encrypting malware deployed, new findings show. "Virtualization platforms are a core component of organizational IT infrastructure, yet they often suffer from inherent misconfigurations and vulnerabilities, making them a lucrative and highly effective target for threat actors to abuse," cybersecurity firm Sygnia  said  in a report shared with The Hacker News. The Israeli company, through its incident response efforts involving various ransomware families like LockBit, HelloKitty, BlackMatter, RedAlert (N13V), Scattered Spider, Akira, Cactus, BlackCat and Cheerscrypt, found that attacks on virtualization environments adhere to a similar sequence of actions. This includes the following steps - Obtaining initial access through phishing attacks, malicious file downloads, and exploitation of known vulnerabilities in internet-facing assets Escalating their privilege

An Iranian threat actor affiliated with the Ministry of Intelligence and Security (MOIS) has been attributed as behind destructive wiping attacks targeting Albania and Israel under the personas Homeland Justice and Karma, respectively. Cybersecurity firm Check Point is tracking the activity under the moniker  Void Manticore , which is also referred to as  Storm-0842  (formerly DEV-0842) by Microsoft. "There are clear overlaps between the targets of Void Manticore and  Scarred Manticore , with indications of systematic hand off of targets between those two groups when deciding to conduct destructive activities against existing victims of Scarred Manticore," the company  said  in a report published today. The threat actor is known for its disruptive cyber attacks against Albania since July 2022 under the name Homeland Justice that involve the use of bespoke wiper malware called  Cl Wiper  and  No-Justice  (aka LowEraser). Similar wiper malware attacks have also targeted Wi

Security researchers have disclosed almost a dozen security flaws impacting the GE HealthCare Vivid Ultrasound product family that could be exploited by malicious actors to tamper with patient data and even install ransomware under certain circumstances. "The impacts enabled by these flaws are manifold: from the implant of ransomware on the ultrasound machine to the access and manipulation of patient data stored on the vulnerable devices," operational technology (OT) security vendor Nozomi Networks  said  in a technical report. The security issues impact the Vivid T9 ultrasound system and its pre-installed Common Service Desktop web application, which is exposed on the localhost interface of the device and allows users to perform administrative actions. They also affect another software program called EchoPAC that's installed on a doctor's Windows workstation to help them access multi-dimensional echo, vascular, and abdominal ultrasound images. That being said, s

The Microsoft Threat Intelligence team said it has observed a threat actor it tracks under the name  Storm-1811  abusing the client management tool Quick Assist to target users in social engineering attacks. "Storm-1811 is a financially motivated cybercriminal group known to deploy  Black Basta  ransomware," the company  said  in a report published on May 15, 2024. The attack chain involves the use of impersonation through voice phishing to trick unsuspecting victims into installing remote monitoring and management (RMM) tools, followed by the delivery of  QakBot , Cobalt Strike, and ultimately Black Basta ransomware. "Threat actors misuse Quick Assist features to perform social engineering attacks by pretending, for example, to be a trusted contact like Microsoft technical support or an IT professional from the target user's company to gain initial access to a target device," the tech giant said. Quick Assist is a  legitimate application  from Microsoft t

Cybersecurity researchers have uncovered an ongoing social engineering campaign that bombards enterprises with spam emails with the goal of obtaining initial access to their environments for follow-on exploitation. "The incident involves a threat actor overwhelming a user's email with junk and calling the user, offering assistance," Rapid7 researchers Tyler McGraw, Thomas Elkins, and Evan McCann  said . "The threat actor prompts impacted users to download remote monitoring and management software like AnyDesk or utilize Microsoft's built-in Quick Assist feature in order to establish a remote connection." The novel campaign is said to be underway since late April 2024, with the emails primarily consisting of newsletter sign-up confirmation messages from legitimate organizations and done so with an aim to overwhelm email protection solutions. The impacted users are then approached over phone calls by masquerading as the company's IT team, tricking the

The Black Basta ransomware-as-a-service (RaaS) operation has targeted more than 500 private industry and critical infrastructure entities in North America, Europe, and Australia since its emergence in April 2022. In a joint advisory published by the Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), the Department of Health and Human Services (HHS), and the Multi-State Information Sharing and Analysis Center (MS-ISAC), the agencies said the threat actors encrypted and stole data from at least 12 out of 16 critical infrastructure sectors. "Black Basta affiliates use common initial access techniques — such as phishing and exploiting known vulnerabilities — and then employ a double-extortion model, both encrypting systems and exfiltrating data," the bulletin  read . Unlike other ransomware groups, the ransom notes dropped at the end of the attack do not contain an initial ransom demand or payment instructions. Rather, the note
