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 pac...

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  ...

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 check...

Multiple security vulnerabilities have been disclosed in F5 BIG-IP and BIG-IQ devices that, if successfully exploited, to completely compromise affected systems. Cybersecurity firm Rapid7 said the  flaws  could be abused to remote access to the devices and defeat security constraints. The issues impact BIG-IP versions 13.x, 14.x, 15.x, 16.x, and 17.x, and BIG-IQ Centralized Management versions 7.x and 8.x. The two high-severity issues, which were reported to F5 on August 18, 2022, are as follows - CVE-2022-41622  (CVSS score: 8.8) - A cross-site request forgery ( CSRF ) vulnerability through iControl SOAP, leading to unauthenticated remote code execution. CVE-2022-41800  (CVSS score: 8.7) - An iControl REST vulnerability that could allow an authenticated user with an Administrator role to bypass  Appliance mode  restrictions. "By successfully exploiting the worst of the vulnerabilities (CVE-2022-41622), an attacker could gain persistent root access...

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   ab...

Hackers tied to the North Korean government have been observed using an updated version of a backdoor known as Dtrack targeting a wide range of industries in Germany, Brazil, India, Italy, Mexico, Switzerland, Saudi Arabia, Turkey, and the U.S. "Dtrack allows criminals to upload, download, start or delete files on the victim host," Kaspersky researchers Konstantin Zykov and Jornt van der Wiel  said  in a report. The victimology patterns indicate an expansion to Europe and Latin America. Sectors targeted by the malware are education, chemical manufacturing, governmental research centers and policy institutes, IT service providers, utility providers, and telecommunication firms. Dtrack, also called Valefor and Preft, is the handiwork of Andariel, a subgroup of the  Lazarus nation-state threat actor  that's publicly tracked by the broader cybersecurity community using the monikers Operation Troy, Silent Chollima, and Stonefly. Discovered in September 2019, the mal...
