The threat actors behind  RTM Locker  have developed a ransomware strain that's capable of targeting Linux machines, marking the group's first foray into the open source operating system. "Its locker ransomware infects Linux, NAS, and ESXi hosts and appears to be inspired by  Babuk  ransomware's leaked source code," Uptycs said in a new report published Wednesday. "It uses a combination of  ECDH  on Curve25519 (asymmetric encryption) and  Chacha20  (symmetric encryption) to encrypt files." RTM Locker was  first documented  by Trellix earlier this month, describing its developers as a private ransomware-as-a-service (RaaS) provider. It has its roots in a cybercrime group called Read The Manual (RTM) that's known to be active since at least 2015. The group is notable for deliberately avoiding high-profile targets such as critical infrastructure, law enforcement, and hospitals so as to draw as little attention as possible. It also lev...

Microsoft has confirmed that the  active exploitation of PaperCut servers  is linked to attacks that are designed to deliver Cl0p and LockBit ransomware families. The tech giant's threat intelligence team is attributing a subset of the intrusions to a financially motivated actor it tracks under the name  Lace Tempest  (formerly DEV-0950), which overlaps with other hacking groups like FIN11, TA505, and Evil Corp. "In observed attacks, Lace Tempest ran multiple PowerShell commands to deliver a TrueBot DLL, which connected to a C2 server, attempted to steal LSASS credentials, and injected the  TrueBot payload  into the conhost.exe service," Microsoft  said  in a series of tweets. The next phase of the attack entailed the deployment of Cobalt Strike Beacon implant to conduct reconnaissance, move laterally across the network using WMI, and exfiltrate files of interest via the file-sharing service MegaSync. Lace Tempest is a Cl0p ransomware affilia...

The Chinese nation-state group dubbed  Alloy Taurus  is using a Linux variant of a backdoor called PingPull as well as a new undocumented tool codenamed Sword2033. That's according to findings from Palo Alto Networks Unit 42, which  discovered  recent malicious cyber activity carried out by the group targeting South Africa and Nepal. Alloy Taurus is the constellation-themed moniker assigned to a threat actor that's known for its attacks targeting telecom companies since at least 2012. It's also tracked by Microsoft as Granite Typhoon (previously Gallium). Last month, the adversary was attributed to a campaign called  Tainted Love  targeting telecommunication providers in the Middle East as part of a broader operation referred to as Soft Cell. Recent cyber espionage attacks mounted by Alloy Taurus have also broadened their victimology footprint to include financial institutions and government entities. PingPull,  first documented  by Unit 42...

The prolific Iranian nation-state group known as  Charming Kitten  is actively targeting multiple victims in the U.S., Europe, the Middle East and India with a novel malware dubbed  BellaCiao , adding to its ever-expanding list of custom tools. Discovered by Bitdefender Labs, BellaCiao is a "personalized dropper" that's capable of delivering other malware payloads onto a victim machine based on commands received from an actor-controlled server. "Each sample collected was tied up to a specific victim and included hard-coded information such as company name, specially crafted subdomains, or associated public IP address," the Romanian cybersecurity firm  said  in a report shared with The Hacker News. Charming Kitten, also known as APT35, Cobalt Illusion, Educated Manticore, ITG18, Mint Sandstorm (née Phosphorus), TA453, and Yellow Garuda, is an Iranian state-sponsored APT group associated with the Islamic Revolutionary Guard Corps ( IRGC ). Over the years, the...

The advanced persistent threat (APT) group referred to as  Evasive Panda  has been observed targeting an international non-governmental organization (NGO) in Mainland China with malware delivered via update channels of legitimate applications like Tencent QQ. The attack chains are designed to distribute a Windows installer for MgBot malware, ESET security researcher Facundo Muñoz said in a new report published today. The activity commenced in November 2020 and continued throughout 2021. Evasive Panda, also known as Bronze Highland and Daggerfly, is a Chinese-speaking APT group that has been attributed to a series of  cyber espionage attacks  targeting various entities in China, Hong Kong, and other countries located in East and South Asia since at least late December 2012. The group's hallmark is the use of the custom MgBot modular malware framework, which is capable of receiving additional components on the fly to expand on its intelligence-gathering capabiliti...

The maintainers of the  Apache Superset  open source data visualization software have released fixes to plug an insecure default configuration that could lead to remote code execution. The vulnerability, tracked as  CVE-2023-27524  (CVSS score: 8.9), impacts versions up to and including 2.0.1 and relates to the use of a default SECRET_KEY that could be abused by attackers to authenticate and access unauthorized resources on internet-exposed installations. Naveen Sunkavally, the chief architect at Horizon3.ai, described the issue as "a dangerous default configuration in Apache Superset that allows an unauth attacker to gain remote code execution, harvest credentials, and compromise data." It's worth noting that the flaw does not affect Superset instances that have changed the default value for the SECRET_KEY config to a more cryptographically secure random string. The cybersecurity firm, which found that the SECRET_KEY is defaulted to the value "\x02\x01thisismy...

VMware has released updates to resolve multiple security flaws impacting its Workstation and Fusion software, the most critical of which could allow a local attacker to achieve code execution. The vulnerability, tracked as CVE-2023-20869 (CVSS score: 9.3), is described as a stack-based buffer-overflow vulnerability that resides in the functionality for sharing host Bluetooth devices with the virtual machine. "A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host," the company  said . Also patched by VMware is an out-of-bounds read vulnerability affecting the same feature (CVE-2023-20870, CVSS score: 7.1), that could be abused by a local adversary with admin privileges to read sensitive information contained in hypervisor memory from a virtual machine. Both vulnerabilities were  demonstrated  by researchers from STAR Labs on the third day of the Pwn2O...

Details have emerged about a high-severity security vulnerability impacting Service Location Protocol ( SLP ) that could be weaponized to launch volumetric denial-of-service attacks against targets. "Attackers exploiting this vulnerability could leverage vulnerable instances to launch massive Denial-of-Service (DoS) amplification attacks with a factor as high as 2,200 times, potentially making it one of the largest amplification attacks ever reported," researchers Pedro Umbelino from Bitsight and Marco Lux from Curesec  said  in a report shared with The Hacker News.

An Iranian nation-state threat actor has been linked to a new wave of phishing attacks targeting Israel that's designed to deploy an updated version of a Windows backdoor called PowerLess . Cybersecurity firm Check Point is tracking the activity cluster under its mythical creature handle  Educated Manticore , which exhibits "strong overlaps" with a hacking crew known as APT35, Charming Kitten, Cobalt Illusion, ITG18, Mint Sandstorm (formerly Phosphorus), TA453, and Yellow Garuda. "Like many other actors, Educated Manticore has adopted recent trends and started using ISO images and possibly other archive files to initiate infection chains," the Israeli company  said  in a technical report published today. Active since at least 2011, APT35 has cast a  wide net of targets  by leveraging  fake social media personas ,  spear-phishing techniques , and  N-day vulnerabilities in internet-exposed applications  to gain initial access and drop vario...

Managing vulnerabilities in the constantly evolving technological landscape is a difficult task. Although vulnerabilities emerge regularly, not all vulnerabilities present the same level of risk. Traditional metrics such as CVSS score or the number of vulnerabilities are insufficient for effective vulnerability management as they lack business context, prioritization, and understanding of attackers' opportunities. Vulnerabilities only represent a small part of the attack surface that attackers can leverage. Initially, organizations used manual methods to address known security weaknesses, but as technology and cyber threats evolved, a more automated and comprehensive approach became necessary. However, legacy vulnerability management tools were designed primarily for compliance and modern tools still face challenges in prioritization and limited resources, especially in dynamic and agile cloud environments. Modern vulnerability management integrates security tools such as scanne...
