CACTUS Ransomware Exploits Qlik Sense Vulnerabilities in Targeted Attacks
Nov 30, 2023
Ransomware / Vulnerability
A CACTUS ransomware campaign has been observed exploiting recently disclosed security flaws in a cloud analytics and business intelligence platform called Qlik Sense to obtain a foothold into targeted environments. "This campaign marks the first documented instance [...] where threat actors deploying CACTUS ransomware have exploited vulnerabilities in Qlik Sense for initial access," Arctic Wolf researchers Stefan Hostetler, Markus Neis, and Kyle Pagelow said . The cybersecurity company, which said it's responding to "several instances" of exploitation of the software, noted that the attacks are likely taking advantage of three flaws that have been disclosed over the past three months - CVE-2023-41265 (CVSS score: 9.9) - An HTTP Request Tunneling vulnerability that allows a remote attacker to elevate their privilege and send requests that get executed by the backend server hosting the repository application. CVE-2023-41266 (CVSS score: 6.5) - A path tr

Nov 29, 2023
Cyber Attack / Data Breach
Identity services provider Okta has disclosed that it detected "additional threat actor activity" in connection with the October 2023 breach of its support case management system. "The threat actor downloaded the names and email addresses of all Okta customer support system users," the company said in a statement shared with The Hacker News. "All Okta Workforce Identity Cloud (WIC) and Customer Identity Solution (CIS) customers are impacted except customers in our FedRamp High and DoD IL4 environments (these environments use a separate support system NOT accessed by the threat actor). The Auth0/CIC support case management system was not impacted by this incident." On top of that, the adversary is believed to have accessed reports containing contact information of all Okta certified users, some Okta Customer Identity Cloud (CIC) customers, and unspecified Okta employee information. However, it emphasized that the data does not include user credenti

How to Handle Retail SaaS Security on Cyber Monday
Nov 27, 2023
SaaS Security / Cyber Monday
If forecasters are right, over the course of today, consumers will spend $13.7 billion . Just about every click, sale, and engagement will be captured by a CRM platform. Inventory applications will trigger automated re-orders; communication tools will send automated email and text messages confirming sales and sharing shipping information. SaaS applications supporting retail efforts will host nearly all of this behind-the-scenes activity. While retailers are rightfully focused on sales during this time of year, they need to ensure that the SaaS apps supporting their business operations are secure. No one wants a repeat of one of the biggest retail cyber-snafus in history, like when one U.S.-based national retailer had 40 million credit card records stolen. The attack surface is vast and retailers must remain vigilant in protecting their entire SaaS app stack. For example, many often use multiple instances of the same application. They may use a different Salesforce tenant for eve
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
Key Cybercriminals Behind Notorious Ransomware Families Arrested in Ukraine
Nov 28, 2023
Ransomware / Cybercrime
A coordinated law enforcement operation has led to the arrest of key individuals in Ukraine who are alleged to be a part of several ransomware schemes. "On 21 November, 30 properties were searched in the regions of Kyiv, Cherkasy, Rivne, and Vinnytsia, resulting in the arrest of the 32-year-old ringleader," Europol said in a statement today. "Four of the ringleader's most active accomplices were also detained." The development comes more than two years after 12 people were apprehended in connection with the same operation. The individuals are primarily linked to LockerGoga, MegaCortex, and Dharma ransomware families. The suspects are estimated to have targeted over 1,800 victims across 71 countries since 2019. They have also been accused of deploying the now-defunct Hive ransomware against high-profile organizations. Some of the co-conspirators are believed to be involved in penetrating IT networks by orchestrating brute-force attacks, SQL injectio
LockBit Ransomware Exploiting Critical Citrix Bleed Vulnerability to Break In
Nov 22, 2023
Threat Analysis / Vulnerability
Multiple threat actors, including LockBit ransomware affiliates, are actively exploiting a recently disclosed critical security flaw in Citrix NetScaler application delivery control (ADC) and Gateway appliances to obtain initial access to target environments. The joint advisory comes from the U.S. Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), Multi-State Information Sharing and Analysis Center (MS-ISAC), and Australian Signals Directorate's Australian Cyber Security Center (ASD's ACSC). "Citrix Bleed, known to be leveraged by LockBit 3.0 affiliates, allows threat actors to bypass password requirements and multifactor authentication (MFA), leading to successful session hijacking of legitimate user sessions on Citrix NetScaler web application delivery control (ADC) and Gateway appliances," the agencies said . "Through the takeover of legitimate user sessions, malicious actors acquire elevated permissions to
