DJVU Ransomware's Latest Variant 'Xaro' Disguised as Cracked Software

DJVU Ransomware's Latest Variant 'Xaro' Disguised as Cracked Software

Nov 29, 2023 Ransomware / Cyber Threat
A variant of a ransomware strain known as DJVU has been observed to be distributed in the form of cracked software. "While this attack pattern is not new, incidents involving a DJVU variant that appends the .xaro extension to affected files and demanding ransom for a decryptor have been observed infecting systems alongside a host of various commodity loaders and infostealers," Cybereason security researcher Ralph Villanueva  said . The new variant has been codenamed Xaro by the American cybersecurity firm. DJVU, in itself, is a  variant of the STOP ransomware , typically arrives on the scene masquerading as legitimate services or applications. It's also delivered as a payload of  SmokeLoader . A significant aspect of DJVU attacks is the deployment of additional malware, such as information stealers (e.g., RedLine Stealer and Vidar), making them more damaging in nature. In the latest attack chain documented by Cybereason, Xaro is propagated as an archive file from a
New "Whiffy Recon" Malware Triangulates Infected Device Location via Wi-Fi Every Minute

New "Whiffy Recon" Malware Triangulates Infected Device Location via Wi-Fi Every Minute

Aug 24, 2023 Malware / Privacy
The SmokeLoader malware is being used to deliver a new Wi-Fi scanning malware strain called  Whiffy Recon  on compromised Windows machines. "The new malware strain has only one operation. Every 60 seconds it triangulates the infected systems' positions by scanning nearby Wi-Fi access points as a data point for Google's geolocation API," Secureworks Counter Threat Unit (CTU)  said  in a statement shared with The Hacker News. "The location returned by Google's  Geolocation API  is then sent back to the adversary." SmokeLoader , as the name implies, is a loader malware whose sole purpose is to drop additional payloads onto a host. Since 2014, the malware has been  offered for sale  to Russian-based threat actors. It's traditionally distributed via phishing emails. Whiffy Recon works by checking for the WLAN AutoConfig service (WLANSVC) on the infected system and terminating itself if the service name doesn't exist. It's worth noting that th
SaaS Compliance through the NIST Cybersecurity Framework

SaaS Compliance through the NIST Cybersecurity Framework

Feb 20, 2024Cybersecurity Framework / SaaS Security
The US National Institute of Standards and Technology (NIST) cybersecurity framework is one of the world's most important guidelines for securing networks. It can be applied to any number of applications, including SaaS.  One of the challenges facing those tasked with securing SaaS applications is the different settings found in each application. It makes it difficult to develop a configuration policy that will apply to an HR app that manages employees, a marketing app that manages content, and an R&D app that manages software versions, all while aligning with NIST compliance standards.  However, there are several settings that can be applied to nearly every app in the SaaS stack. In this article, we'll explore some universal configurations, explain why they are important, and guide you in setting them in a way that improves your SaaS apps' security posture.  Start with Admins Role-based access control (RBAC) is a key to NIST adherence and should be applied to every SaaS a
CERT-UA Warns of SmokeLoader and RoarBAT Malware Attacks Against Ukraine

CERT-UA Warns of SmokeLoader and RoarBAT Malware Attacks Against Ukraine

May 08, 2023 Cyber Attack / Data Safety
An ongoing phishing campaign with invoice-themed lures is being used to distribute the SmokeLoader malware in the form of a polyglot file, according to the Computer Emergency Response Team of Ukraine (CERT-UA). The emails, per the  agency , are sent using compromised accounts and come with a ZIP archive that, in reality, is a  polyglot file  containing a decoy document and a JavaScript file. The JavaScript code is then used to launch an executable that paves for the execution of the  SmokeLoader malware . SmokeLoader, first detected in 2011, is a  loader  whose main objective is to download or load a stealthier or more effective malware onto infected systems. CERT-UA attributed the activity to a threat actor it calls UAC-0006 and characterized it as a financially motivated operation carried out with the goal of stealing credentials and making unauthorized fund transfers. In a related advisory, Ukraine's cybersecurity authority also revealed details of destructive attacks orch

Cybersecurity Experts Uncover Inner Workings of Destructive Azov Ransomware

Cybersecurity Experts Uncover Inner Workings of Destructive Azov Ransomware

Dec 13, 2022 Data Security / Endpoint Security
Cybersecurity researchers have published the inner workings of a new wiper called  Azov Ransomware  that's deliberately designed to corrupt data and "inflict impeccable damage" to compromised systems. Distributed through another malware loader known as  SmokeLoader , the malware has been  described  as an "effective, fast, and unfortunately unrecoverable data wiper," by Israeli cybersecurity company Check Point. Its origins have yet to be determined. The wiper routine is set to overwrite a file's contents in alternating 666-byte chunks with random noise, a technique referred to as  intermittent encryption  that's being increasingly leveraged by ransomware operators to evade detection and encrypt victims' files faster. "One thing that sets Azov apart from your garden-variety ransomware is its modification of certain 64-bit executables to execute its own code," threat researcher Jiří Vinopal said. "The modification of executables is
New Laplas Clipper Malware Targeting Cryptocurrency Users via SmokeLoader

New Laplas Clipper Malware Targeting Cryptocurrency Users via SmokeLoader

Nov 08, 2022
Cryptocurrency users are being targeted with a new clipper malware strain dubbed  Laplas  by means of another malware known as SmokeLoader. SmokeLoader, which is delivered by means of weaponized documents sent through spear-phishing emails, further acts as a conduit for other  commodity trojans  like  SystemBC  and  Raccoon Stealer 2.0 , according to an  analysis  from Cyble. Observed in the wild since circa 2013,  SmokeLoader  functions as a generic loader capable of distributing additional payloads onto compromised systems, such as information-stealing malware and other implants. In July 2022, it was found to deploy a backdoor called  Amadey . Cyble said it discovered over 180 samples of the Laplas since October 24, 2022, suggesting a wide deployment. Clippers, also called ClipBankers, fall under a category of malware that Microsoft calls  cryware , which are designed to steal crypto by keeping close tabs on a victim's clipboard activity and swapping the original wallet ad
