The U.S. Federal Bureau of Investigation (FBI) on Monday announced the disruption of online infrastructure associated with a nascent ransomware group called Radar/Dispossessor. The effort saw the dismantling of three U.S. servers, three United Kingdom servers, 18 German servers, eight U.S.-based criminal domains, and one German-based criminal domain. Dispossessor is said to be led by individual(s) who go by the online moniker "Brain." "Since its inception in August 2023, Radar/Dispossessor has quickly developed into an internationally impactful ransomware group, targeting and attacking small-to-mid-sized businesses and organizations from the production, development, education, healthcare, financial services, and transportation sectors," the FBI said in a statement. As many as 43 companies have been identified as victims of Dispossessor attacks, including those located in Argentina, Australia, Belgium, Brazil, Canada, Croatia, Germany, Honduras, India, Peru, Pol

The ransomware strain known as BlackSuit has demanded as much as $500 million in ransoms to date, with one individual ransom demand hitting $60 million. That's according to an updated advisory from the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI). "BlackSuit actors have exhibited a willingness to negotiate payment amounts," the agencies said . "Ransom amounts are not part of the initial ransom note, but require direct interaction with the threat actor via a .onion URL (reachable through the Tor browser) provided after encryption." Attacks involving ransomware have targeted several critical infrastructure sectors spanning commercial facilities, healthcare and public health, government facilities, and critical manufacturing. An evolution of the Royal ransomware , it leverages the initial access obtained via phishing emails to disarm antivirus software and exfiltrate sensitive data before ultimately

Want to know what's the latest and greatest in SecOps for 2024? Gartner's recently released Hype Cycle for Security Operations report takes important steps to organize and mature the domain of Continuous Threat Exposure Management, aka CTEM. Three categories within this domain are included in this year's report: Threat Exposure Management, Exposure Assessment Platforms (EAP), and Adversarial Exposure Validation (AEV). These category definitions are aimed at providing some structure to the evolving landscape of exposure management technologies. Pentera, listed as a sample vendor in the newly defined AEV category, is playing a pivotal role in increasing the adoption of CTEM, with a focus on security validation. Following is our take on the CTEM related product categories and what they mean for enterprise security leaders. The Industry is Maturing CTEM, coined by Gartner in 2022, presents a structural approach for continuously assessing, prioritizing, validating, and remediating expo

As more people work remotely, IT departments must manage devices distributed over different cities and countries relying on VPNs and remote monitoring and management (RMM) tools for system administration.  However, like any new technology, RMM tools can also be used maliciously. Threat actors can establish connections to a victim's device and run commands, exfiltrate data, and stay undetected.  This article will cover real-world examples of RMM exploits and show you how to protect your organization from these attacks.  What are RMM tools?  RMM software simplifies network management, allowing IT professionals to remotely solve problems, install software, and upload or download files to or from devices.  Unfortunately, this connection is not always secure, and attackers can use malicious software to connect their servers to a victim's device. As these connections become easier to detect, however,  ransomware-as-a-service (RaaS) groups have had to adjust their methods.  In

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.  The deep and dark web, otherwise known as the cybercriminal underground, is where malicious actors gather to exchange plans, sell goods or services, and recruit others to help in their illicit activities. Grasping how it functions and the intelligence it offers is crucial for proactively safeguarding your environment against attacks, as it is in these spaces that threat actors frequently reveal their intentions prior to launching an attack. The State of the Underground 2024 Our annual State of the Underground 2024 is a detailed report that sheds light on the evolving underworld of cybercrime, exploring trends and behaviors observed within the deep, dark web during 2023.

A recently patched security flaw impacting VMware ESXi hypervisors has been actively exploited by "several" ransomware groups to gain elevated permissions and deploy file-encrypting malware. The attacks involve the exploitation of CVE-2024-37085 (CVSS score: 6.8), an Active Directory integration authentication bypass that allows an attacker to obtain administrative access to the host. "A malicious actor with sufficient Active Directory (AD) permissions can gain full access to an ESXi host that was previously configured to use AD for user management by re-creating the configured AD group ('ESXi Admins' by default) after it was deleted from AD," Broadcom-owned VMware noted in an advisory released in late June 2024. In other words, escalating privileges on ESXi to the administrator was as simple as creating a new AD group named "ESX Admins" and adding any user to it, or renaming any group in the domain to "ESX Admins" and adding a user

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

The JavaScript downloader malware known as SocGholish (aka FakeUpdates) is being used to deliver a remote access trojan called AsyncRAT as well as a legitimate open-source project called BOINC. BOINC , short for Berkeley Open Infrastructure Network Computing Client, is an open-source "volunteer computing" platform maintained by the University of California with an aim to carry out "large-scale distributed high-throughput computing" using participating home computers on which the app is installed. "It's similar to a cryptocurrency miner in that way (using computer resources to do work), and it's actually designed to reward users with a specific type of cryptocurrency called Gridcoin, designed for this purpose," Huntress researchers Matt Anderson, Alden Schmidt, and Greg Linares said in a report published last week. These malicious installations are designed to connect to an actor-controlled domain ("rosettahome[.]cn" or "rosettah

Cybersecurity researchers have discovered a new Linux variant of a ransomware strain known as Play (aka Balloonfly and PlayCrypt) that's designed to target VMware ESXi environments. "This development suggests that the group could be broadening its attacks across the Linux platform, leading to an expanded victim pool and more successful ransom negotiations," Trend Micro researchers said in a report published Friday. Play, which arrived on the scene in June 2022, is known for its double extortion tactics, encrypting systems after exfiltrating sensitive data and demanding payment in exchange for a decryption key. According to estimates released by Australia and the U.S., as many as 300 organizations have been victimized by the ransomware group as of October 2023. Statistics shared by Trend Micro for the first seven months of 2024 show that the U.S. is the country with the highest number of victims, followed by Canada, Germany, the U.K., and the Netherlands. Manufactu

Law enforcement officials in the U.K. have arrested a 17-year-old boy from Walsall who is suspected to be a member of the notorious Scattered Spider cybercrime syndicate. The arrest was made "in connection with a global cyber online crime group which has been targeting large organizations with ransomware and gaining access to computer networks," West Midlands police said . "The arrest is part of a global investigation into a large-scale cyber hacking community which has targeted a number of major companies which includes MGM Resorts in America." The teen's arrest, carried out in coordination with the U.K. National Crime Agency (NCA) and the U.S. Federal Bureau of Investigation (FBI), comes a little over a month after another 22-year-old member of the e-crime gang from the U.K. was apprehended in Spain. Scattered Spider, an offshoot of a loose-knit group called The Com, has evolved into an initial access broker and affiliate, delivering ransomware familie

Two Russian nationals have pleaded guilty in a U.S. court for their participation as affiliates in the LockBit ransomware scheme and helping facilitate ransomware attacks across the world. The defendants include Ruslan Magomedovich Astamirov, 21, of Chechen Republic, and Mikhail Vasiliev, 34, a dual Canadian and Russian national of Bradford, Ontario. Astamirov was arrested in Arizona by U.S. law enforcement agencies in May 2023. Vasiliev, who is already wanted for similar charges in Canada, was sentenced to nearly four years in jail. He was subsequently extradited to the U.S. last month. The development comes more than two months after the U.K. National Crime Agency (NCA) unmasked a 31-year-old Russian national named Dmitry Yuryevich Khoroshev as the administrator and developer of the LockBit ransomware operation. LockBit, which is estimated to have attacked over 2,500 entities since its appearance towards the end of 2019, raking in at least approximately $500 million in ranso

The financially motivated threat actor known as FIN7 has been observed using multiple pseudonyms across several underground forums to likely advertise a security dodging tool known to be used by ransomware groups like AvosLocker, Black Basta, BlackCat, LockBit, and Trigona. "AvNeutralizer (aka AuKill ), a highly specialized tool developed by FIN7 to tamper with security solutions, has been marketed in the criminal underground and used by multiple ransomware groups," cybersecurity company SentinelOne said in a report shared with The Hacker News. FIN7, an e-crime group of Russian and Ukrainian origin, has been a persistent threat since at least 2012, shifting gears from its initial targeting of point-of-sale (PoS) terminals to acting as a ransomware affiliate for now-defunct gangs such as REvil and Conti, before launching its own ransomware-as-a-service (RaaS) programs DarkSide and BlackMatter. The threat actor, which is also tracked under the names Carbanak, Carbon Spide

The infamous cybercrime group known as Scattered Spider has incorporated ransomware strains such as RansomHub and Qilin into its arsenal, Microsoft has revealed. Scattered Spider is the designation given to a threat actor that's known for its sophisticated social engineering schemes to breach targets and establish persistence for follow-on exploitation and data theft. It also has a history of targeting VMWare ESXi servers and deploying BlackCat ransomware. It shares overlaps with activity clusters tracked by the broader cybersecurity community under the monikers Gold Harvest, 0ktapus, Octo Tempest, and UNC3944. Last month, it was reported that a key member of the group was arrested in Spain. RansomHub, which arrived on the scene earlier this February, has been assessed to be a rebrand of another ransomware strain called Knight, according to an analysis from Broadcom-owned Symantec last month. "RansomHub is a ransomware-as-a-service (RaaS) payload used by more and mor

Cybersecurity researchers have shed light on a new version of a ransomware strain called HardBit that comes packaged with new obfuscation techniques to deter analysis efforts. "Unlike previous versions, HardBit Ransomware group enhanced the version 4.0 with passphrase protection," Cybereason researchers Kotaro Ogino and Koshi Oyama said in an analysis. "The passphrase needs to be provided during the runtime in order for the ransomware to be executed properly. Additional obfuscation hinders security researchers from analyzing the malware." HardBit, which first emerged in October 2022, is a financially motivated threat actor that, similar to other ransomware groups, operates with an aim to generate illicit revenues via double extortion tactics. What makes the threat group stand out is that it does not operate a data leak site, and instead pressurizes victims to pay up by threatening to conduct additional attacks in the future. Its primary mode of communication

A now-patched security flaw in Veeam Backup & Replication software is being exploited by a nascent ransomware operation known as EstateRansomware. Singapore-headquartered Group-IB, which discovered the threat actor in early April 2024, said the modus operandi involved the exploitation of CVE-2023-27532 (CVSS score: 7.5) to carry out the malicious activities. Initial access to the target environment is said to have been facilitated by means of a Fortinet FortiGate firewall SSL VPN appliance using a dormant account. "The threat actor pivoted laterally from the FortiGate Firewall through the SSL VPN service to access the failover server," security researcher Yeo Zi Wei said in an analysis published today. "Before the ransomware attack, there were VPN brute-force attempts noted in April 2024 using a dormant account identified as 'Acc1.' Several days later, a successful VPN login using 'Acc1' was traced back to the remote IP address 149.28.106[.]25
