LodaRAT Malware Resurfaces with New Variants Employing Updated Functionalities

LodaRAT Malware Resurfaces with New Variants Employing Updated Functionalities

Nov 18, 2022
The LodaRAT malware has resurfaced with new variants that are being deployed in conjunction with other sophisticated malware, such as RedLine Stealer and Neshta. "The ease of access to its source code makes LodaRAT an attractive tool for any threat actor who is interested in its capabilities," Cisco Talos researcher Chris Neal  said  in a write-up published Thursday. Aside from being dropped alongside other malware families, LodaRAT has also been observed being delivered through a previously unknown variant of another commodity trojan called  Venom RAT , which has been codenamed S500. An AutoIT-based malware, LodaRAT (aka  Nymeria ) is attributed to a group called Kasablanca and is capable of harvesting sensitive information from compromised machines. In February 2021, an  Android version  of the malware sprang forth as a way for the threat actors to expand their attack surface. Then in September 2022, Zscaler ThreatLabz uncovered a new delivery mechanism that involved
Threat hunting with MITRE ATT&CK and Wazuh

Threat hunting with MITRE ATT&CK and Wazuh

Nov 18, 2022
Threat hunting is the process of looking for malicious activity and its artifacts in a computer system or network. Threat hunting is carried out intermittently in an environment regardless of whether or not threats have been discovered by automated security solutions. Some threat actors may stay dormant in an organization's infrastructure, extending their access while waiting for the right opportunity to exploit discovered weaknesses. Therefore it is important to perform threat hunting to identify malicious actors in an environment and stop them before they achieve their ultimate goal.  To effectively perform threat hunting, the threat hunter must have a systematic approach to emulating possible adversary behavior. This adversarial behavior determines what artifacts can be searched for that indicate ongoing or past malicious activity. MITRE ATT&CK Over the years, the security community has observed that threat actors have commonly used many tactics, techniques, and procedu
How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

Mar 21, 2024SaaS Security / Endpoint Security
In today's digital-first business environment dominated by SaaS applications, organizations increasingly depend on third-party vendors for essential cloud services and software solutions. As more vendors and services are added to the mix, the complexity and potential vulnerabilities within the  SaaS supply chain  snowball quickly. That's why effective vendor risk management (VRM) is a critical strategy in identifying, assessing, and mitigating risks to protect organizational assets and data integrity. Meanwhile, common approaches to vendor risk assessments are too slow and static for the modern world of SaaS. Most organizations have simply adapted their legacy evaluation techniques for on-premise software to apply to SaaS providers. This not only creates massive bottlenecks, but also causes organizations to inadvertently accept far too much risk. To effectively adapt to the realities of modern work, two major aspects need to change: the timeline of initial assessment must shorte

Hive Ransomware Attackers Extorted $100 Million from Over 1,300 Companies Worldwide

Nov 18, 2022
The threat actors behind the Hive ransomware-as-a-service (RaaS) scheme have launched attacks against over 1,300 companies across the world, netting the gang $100 million in illicit payments as of November 2022. "Hive ransomware has targeted a wide range of businesses and critical infrastructure sectors, including government facilities, communications, critical manufacturing, information technology, and — especially — Healthcare and Public Health (HPH)," U.S. cybersecurity and intelligence authorities  said  in an alert. Active since June 2021, Hive's RaaS operation involves a mix of developers, who create and manage the malware, and affiliates, who are responsible for conducting the attacks on target networks by often purchasing initial access from initial access brokers (IABs). In most cases, gaining a foothold involves the exploitation of  ProxyShell flaws  in Microsoft Exchange Server, followed by taking steps to terminate processes associated with antivirus engi

W4SP Stealer Constantly Targeting Python Developers in Ongoing Supply Chain Attack

W4SP Stealer Constantly Targeting Python Developers in Ongoing Supply Chain Attack

Nov 18, 2022
An ongoing supply chain attack has been leveraging malicious Python packages to distribute malware called W4SP Stealer, with over hundreds of victims ensnared to date. "The threat actor is still active and is releasing more malicious packages," Checkmarx researcher Jossef Harush  said  in a technical write-up, calling the adversary  WASP . "The attack seems related to cybercrime as the attacker claims that these tools are undetectable to increase sales." The findings from Checkmarx build on recent reports from  Phylum  and  Check Point , which flagged 30 different modules published on the Python Package Index (PyPI) that were designed to propagate malicious code under the guise of benign-looking packages. The attack is just the latest threat to target the software supply chain. What makes it notable is the use of steganography to extract a  polymorphic malware  payload hidden within an image file hosted on Imgur. The installation of the package ultimately mak

Chinese Hackers Using 42,000 Imposter Domains in Massive Phishing Attack Campaign

Nov 17, 2022
A China-based financially motivated group is leveraging the trust associated with popular international brands to orchestrate a large-scale phishing campaign dating back as far as 2019. The threat actor, dubbed Fangxiao by Cyjax, is said to have registered over  42,000 imposter domains , with initial activity observed in 2017. "It targets businesses in multiple verticals including retail, banking, travel, and energy," researchers Emily Dennison and Alana Witten  said . "Promised financial or physical incentives are used to trick victims into further spreading the campaign via WhatsApp." Users clicking on a link sent through the messaging app are directed to an actor-controlled site, which, in turn, sends them to a landing domain impersonating a well-known brand, from where the victims are once again taken to sites distributing fraudulent apps and bogus rewards. These sites prompt the visitors to complete a survey to claim cash prizes, in exchange for which the

A Ukrainian national who has been wanted by the U.S for over a decade has been arrested by Swiss authorities for his role in a notorious cybercriminal ring that stole millions of dollars from victims' bank accounts using malware called Zeus . Vyacheslav Igorevich Penchukov, who went by online pseu­do­nyms "tank" and "father," is alleged to have been involved in the day-to-day operations of the group. He was apprehended in Geneva on October 23, 2022, and is pending extradition to the U.S. Details of the arrest were  first reported  by independent security journalist Brian Krebs. Penchukov, along with Ivan Viktorovich Klepikov (aka "petrovich" and "nowhere") and Alexey Dmitrievich Bron (aka "thehead"), was originally charged in the District of Nebraska in August 2012. According to court documents released by the U.S. Department of Justice (DoJ) in 2014, Penchukov and eight other members of the cybercriminal group  infected  &qu

100 Apps, Endless Security Checks

Nov 17, 2022
On average, organizations  report  using 102 business-critical SaaS applications, enabling operations of most departments across an organization, such as IT and Security, Sales, Marketing, R&D, Product Management, HR, Legal, Finance, and Enablement. An attack can come from any app, no matter how robust the app is. Without visibility and control over a critical mass of an organization's entire SaaS app stack, security teams are flying blind. This is why it's important that all SaaS apps across the organization be managed at scale.  While this breadth of coverage is critical, each app has its own characteristics, UI, and terminology. Mitigating these threats requires a deep understanding of all security controls its configurations.  Learn how to automate SaaS security management . Security teams need to map out the entire SaaS ecosystem within the organization, including the core SaaS apps and the numerous additional apps that employees connect to without checking or informing th

Iranian Hackers Compromised a U.S. Federal Agency's Network Using Log4Shell Exploit

Nov 17, 2022
Iranian government-sponsored threat actors have been blamed for compromising a U.S. federal agency by taking advantage of the Log4Shell vulnerability in an unpatched VMware Horizon server. The details, which were shared by the U.S. Cybersecurity and Infrastructure Security Agency (CISA), come in response to incident response efforts undertaken by the authority from mid-June through mid-July 2022. "Cyber threat actors exploited the Log4Shell vulnerability in an unpatched VMware Horizon server, installed XMRig crypto mining software, moved laterally to the domain controller (DC), compromised credentials, and then implanted Ngrok reverse proxies on several hosts to maintain persistence," CISA  noted . LogShell, aka  CVE-2021-44228 , is a critical remote code execution flaw in the widely-used Apache Log4j Java-based logging library. It was addressed by the open source project maintainers in December 2021. The latest development  marks  the  continued   abuse  of the Log4j v
