Cyber Threat | Breaking Cybersecurity News | The Hacker News

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 the current cyber threat landscape, the protection of personal and corporate identities has become vital. Once in the hands of cybercriminals, compromised credentials and accounts provide unauthorized access to corporations' sensitive information and an entry point to launch costly ransomware and other malware attacks. To properly mitigate threats stemming from compromised credentials and accounts, organizations need identity intelligence. Understanding the significance of identity intelligence and the benefits it delivers is foundational to maintaining a secure posture and minimizing risk.  There is a perception that security teams and threat analysts are already overloaded by too much data. By these

Cybersecurity researchers said they discovered an accidentally leaked GitHub token that could have granted elevated access to the GitHub repositories of the Python language, Python Package Index (PyPI), and the Python Software Foundation (PSF). JFrog, which found the GitHub Personal Access Token, said the secret was leaked in a public Docker container hosted on Docker Hub. "This case was exceptional because it is difficult to overestimate the potential consequences if it had fallen into the wrong hands – one could supposedly inject malicious code into PyPI packages (imagine replacing all Python packages with malicious ones), and even to the Python language itself," the software supply chain security company said . An attacker could have hypothetically weaponized their admin access to orchestrate a large-scale supply chain attack by poisoning the source code associated with the core of the Python programming language, or the PyPI package manager. JFrog noted that the aut

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

Cybersecurity researchers have shed light on a short-lived DarkGate malware campaign that leveraged Samba file shares to initiate the infections. Palo Alto Networks Unit 42 said the activity spanned the months of March and April 2024, with the infection chains using servers running public-facing Samba file shares hosting Visual Basic Script (VBS) and JavaScript files. Targets included North America, Europe, and parts of Asia. "This was a relatively short-lived campaign that illustrates how threat actors can creatively abuse legitimate tools and services to distribute their malware," security researchers Vishwa Thothathri, Yijie Sui, Anmol Maurya, Uday Pratap Singh, and Brad Duncan said . DarkGate, which first emerged in 2018, has evolved into a malware-as-a-service (MaaS) offering used by a tightly controlled number of customers. It comes with capabilities to remotely control compromised hosts, execute code, mine cryptocurrency, launch reverse shells, and drop addit

In today's digital age, passwords serve as the keys to our most sensitive information, from social media accounts to banking and business systems. This immense power brings with it significant responsibility—and vulnerability. Most people don't realize their credentials have been compromised until the damage is done. Imagine waking up to drained bank accounts, stolen identities, or a company's reputation in tatters. This isn't just a hypothetical scenario – it's the harsh reality faced by countless individuals and organizations every day. Recent data reveals that compromised credentials are the single biggest attack vector in 2024. That means stolen passwords, not exotic malware or zero-day exploits, are the most common way hackers breach systems and wreak havoc. To help you navigate this critical issue, we invite you to join our exclusive webinar, " Compromised Credentials in 2024: What to Know About the World's #1 Attack Vector. " What You'

Financial institutions in Latin America are being threatened by a banking trojan called Mekotio (aka Melcoz). That's according to findings from Trend Micro, which said it recently observed a surge in cyber attacks distributing the Windows malware. Mekotio , known to be actively put to use since 2015, is known to target Latin American countries like Brazil, Chile, Mexico, Spain, Peru, and Portugal with an aim to steal banking credentials. First documented by ESET in August 2020, it's part of a tetrade of banking trojans targeting the region, such as Guildma, Javali, and Grandoreiro , the latter of which was dismantled by law enforcement earlier this year. "Mekotio shares common characteristics for this type of malware, such as being written in Delphi, using fake pop-up windows, containing backdoor functionality and targeting Spanish- and Portuguese-speaking countries," the Slovakian cybersecurity firm said at the time. The malware operation suffered a blow in

French cloud computing firm OVHcloud said it mitigated a record-breaking distributed denial-of-service (DDoS) attack in April 2024 that reached a packet rate of 840 million packets per second (Mpps). This is just above the previous record of 809 million Mpps reported by Akamai as targeting a large European bank in June 2020. The 840 Mpps DDoS attack is said to have been a combination of a TCP ACK flood that originated from 5,000 source IPs and a DNS reflection attack leveraging about 15,000 DNS servers to amplify the traffic. "While the attack was distributed worldwide, 2/3 of total packets entered from only four [points of presence], all located in the U.S. with 3 of them being on the west coast," OVHcloud noted . "This highlights the capability of the adversary to send a huge packet rate through only a few peerings, which can prove very problematic." The company said it has observed a significant uptick in DDoS attacks in terms of both frequency and intensi

The attack surface isn't what it once was and it's becoming a nightmare to protect. A constantly expanding and evolving attack surface means risk to the business has skyrocketed and current security measures are struggling to keep it protected. If you've clicked on this article, there's a good chance you're looking for solutions to manage this risk. In 2022, a new framework was coined by Gartner to address these challenges - Continuous Threat Exposure Management (CTEM). Since then, putting this framework into action has become a priority across many organizations for the profound improvement it is expected to make toward maintaining a high level of security readiness and resilience.  "By 2026 organizations that prioritize their security investments based on a continuous exposure management program will be three times less likely to suffer a breach." Gartner, "How to Manage Cybersecurity Threats, Not Episodes," August 21, 2023 CTEM provides a continuous and comprehensive view of the

The loader-as-a-service (LaaS) known as FakeBat has become one of the most widespread loader malware families distributed using the drive-by download technique this year, findings from Sekoia reveal. "FakeBat primarily aims to download and execute the next-stage payload, such as IcedID , Lumma , RedLine , SmokeLoader , SectopRAT , and Ursnif ," the company said in a Tuesday analysis. Drive-by attacks entail the use of methods like search engine optimization (SEO) poisoning, malvertising, and nefarious code injections into compromised sites to entice users into downloading bogus software installers or browser updates. The use of malware loaders over the past few years dovetails with the growing use of landing pages impersonating legitimate software websites by passing them off as legitimate installers. This ties into the larger aspect that phishing and social engineering remain one of the threat actors' main ways to acquire initial access. FakeBat , also known as Eu

A new campaign is tricking users searching for the Meta Quest (formerly Oculus) application for Windows into downloading a new adware family called AdsExhaust. "The adware is capable of exfiltrating screenshots from infected devices and interacting with browsers using simulated keystrokes," cybersecurity firm eSentire said in an analysis, adding it identified the activity earlier this month. "These functionalities allow it to automatically click through advertisements or redirect the browser to specific URLs, generating revenue for the adware operators." The initial infection chain involves surfacing the bogus website ("oculus-app[.]com") on Google search results pages using search engine optimization (SEO) poisoning techniques, prompting unsuspecting site visitors to download a ZIP archive ("oculus-app.EXE.zip") containing a Windows batch script. The batch script is designed to fetch a second batch script from a command-and-control (C2) se

The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) imposed sanctions against a dozen individuals serving executive and senior leadership roles at Kaspersky Lab, a day after the Russian company was banned by the Commerce Department. The move "underscores our commitment to ensure the integrity of our cyber domain and to protect our citizens against malicious cyber threats," Under Secretary of the Treasury for Terrorism and Financial Intelligence, Brian E. Nelson, said. "The United States will take action where necessary to hold accountable those who would seek to facilitate or otherwise enable these activities." The sanctions, however, do not extend to Kaspersky Lab, its parent or subsidiary companies, nor the company's founder and chief executive officer (CEO), Eugene Kaspersky, OFAC noted. The 12 C-suite and senior-level executives sanctioned are listed below - Andrei Gennadyevich Tikhonov, Chief Operating Officer (COO) and

A malvertising campaign is leveraging trojanized installers for popular software such as Google Chrome and Microsoft Teams to drop a backdoor called Oyster (aka Broomstick and CleanUpLoader). That's according to findings from Rapid7, which identified lookalike websites hosting the malicious payloads that users are redirected to after searching for them on search engines like Google and Bing. The threat actors are luring unsuspecting users to fake websites purporting to contain legitimate software. But attempting to download the setup binary launches a malware infection chain instead. Specifically, the executable serves as a pathway for a backdoor called Oyster, which is capable of gathering information about the compromised host, communicating with a hard-coded command-and-control (C2) address, and supporting remote code execution. While Oyster has been observed in the past being delivered by means of a dedicated loader component known as Broomstick Loader (aka Oyster Instal

Cyber espionage groups associated with China have been linked to a long-running campaign that has infiltrated several telecom operators located in a single Asian country at least since 2021. "The attackers placed backdoors on the networks of targeted companies and also attempted to steal credentials," the Symantec Threat Hunter Team, part of Broadcom, said in a report shared with The Hacker News. The cybersecurity firm did not reveal the country that was targeted, but said it found evidence to suggest that the malicious cyber activity may have started as far back as 2020. The attacks also targeted an unnamed services company that catered to the telecoms sector and a university in another Asian country, it added. The choice of tools used in this campaign overlaps with other missions conducted by Chinese espionage groups like Mustang Panda (aka Earth Preta and Fireant), RedFoxtrot (aka Neeedleminer and Nomad Panda), and Naikon (aka Firefly) in recent years. This incl

A new Rust-based information stealer malware called Fickle Stealer has been observed being delivered via multiple attack chains with the goal of harvesting sensitive information from compromised hosts. Fortinet FortiGuard Labs said it's aware of four different distribution methods -- namely VBA dropper, VBA downloader, link downloader, and executable downloader -- with some of them using a PowerShell script to bypass User Account Control (UAC) and execute Fickle Stealer. The PowerShell script ("bypass.ps1" or "u.ps1") is also designed to periodically send information about the victim, including country, city, IP address, operating system version, computer name, and username to a Telegram bot controlled by the attacker. The stealer payload, which is protected using a packer, runs a series of anti-analysis checks to determine if it's running in a sandbox or a virtual machine environment, following which it beacons out to a remote server to exfiltrate da

Threat actors have been observed deploying a malware called NiceRAT to co-opt infected devices into a botnet. The attacks, which target South Korean users, are designed to propagate the malware under the guise of cracked software, such as Microsoft Windows, or tools that purport to offer license verification for Microsoft Office. "Due to the nature of crack programs, information sharing amongst ordinary users contributes to the malware's distribution independently from the initial distributor," the AhnLab Security Intelligence Center (ASEC) said . "Because threat actors typically explain ways to remove anti-malware programs during the distribution phase, it is difficult to detect the distributed malware." Alternate distribution vectors involve the use of a botnet comprising zombie computers that are infiltrated by a remote access trojan (RAT) known as NanoCore RAT , mirroring prior activity that leveraged the Nitol DDoS malware for propagating another malware

Cybersecurity researchers have uncovered a new suspicious package uploaded to the npm package registry that's designed to drop a remote access trojan (RAT) on compromised systems. The package in question is glup-debugger-log , which targets users of the gulp toolkit by masquerading as a "logger for gulp and gulp plugins." It has been downloaded 175 times to date. Software supply chain security firm Phylum, which discovered the package, said the software comes fitted with two obfuscated files that work in tandem to deploy the malicious payload. "One worked as a kind of initial dropper setting the stage for the malware campaign by compromising the target machine if it met certain requirements, then downloading additional malware components, and the other script providing the attacker with a persistent remote access mechanism to control the compromised machine," it said . Phylum's closer examination of the library's package.json file – which acts as

Cybersecurity researchers have warned of a new malicious Python package that has been discovered in the Python Package Index (PyPI) repository to facilitate cryptocurrency theft as part of a broader campaign. The package in question is pytoileur , which has been downloaded 316 times as of writing. Interestingly, the package author, who goes by the name PhilipsPY, has uploaded a new version of the package (1.0.2) with identical functionality after a previous version (1.0.1) was yanked by PyPI maintainers on May 28, 2024. According to an analysis released by Sonatype, the malicious code is embedded in the package's setup.py script, allowing it to execute a Base64-encoded payload that's responsible for retrieving a Windows binary from an external server. "The retrieved binary, 'Runtime.exe,' is then run by leveraging Windows PowerShell and VBScript commands on the system," security researcher Ax Sharma said . Once installed, the binary establishes persiste

The threat actors behind the CatDDoS malware botnet have exploited over 80 known security flaws in various software over the past three months to infiltrate vulnerable devices and co-opt them into a botnet for conducting distributed denial-of-service (DDoS) attacks. "CatDDoS-related gangs' samples have used a large number of known vulnerabilities to deliver samples," the QiAnXin XLab team  said . "Additionally, the maximum number of targets has been observed to exceed 300+ per day." The flaws impact routers, networking gear, and other devices from vendors such as Apache (ActiveMQ, Hadoop, Log4j, and RocketMQ), Cacti, Cisco, D-Link, DrayTek, FreePBX, GitLab, Gocloud, Huawei, Jenkins, Linksys, Metabase, NETGEAR, Realtek, Seagate, SonicWall, Tenda, TOTOLINK, TP-Link, ZTE, and Zyxel, among others. CatDDoS was previously documented by  QiAnXin  and  NSFOCUS  in late 2023, describing it as a  Mirai botnet variant  capable of performing DDoS attacks using UDP, TCP,

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
