Cybersecurity researchers have disclosed a new malware campaign that leverages a malware loader named PureCrypter to deliver a commodity remote access trojan (RAT) called DarkVision RAT. The activity, observed by Zscaler ThreatLabz in July 2024, involves a multi-stage process to deliver the RAT payload. "DarkVision RAT communicates with its command-and-control (C2) server using a custom network protocol via sockets," security researcher Muhammed Irfan V A said in an analysis. "DarkVision RAT supports a wide range of commands and plugins that enable additional capabilities such as keylogging, remote access, password theft, audio recording, and screen captures." PureCrypter, first publicly disclosed in 2022, is an off-the-shelf malware loader that's available for sale on a subscription basis, offering customers the ability to distribute information stealers, RATs, and ransomware. The exact initial access vector used to deliver PureCrypter and, by extensio...

In recent years, the number and sophistication of zero-day vulnerabilities have surged, posing a critical threat to organizations of all sizes. A zero-day vulnerability is a security flaw in software that is unknown to the vendor and remains unpatched at the time of discovery. Attackers exploit these flaws before any defensive measures can be implemented, making zero-days a potent weapon for cybercriminals. A recent example is, for instance, CVE-2024-0519 in Google Chrome: this high-severity vulnerability was actively exploited in the wild and involved an out-of-bounds memory access issue in the V8 JavaScript engine. It allowed remote attackers to access sensitive information or trigger a crash by exploiting heap corruption.  Also, the zero-day vulnerability at Rackspace caused massive trouble. This incident was a zero-day remote code execution vulnerability in ScienceLogic's monitoring application that led to the compromise of Rackspace's internal systems. The breach expose...

Threat actors constantly change tactics to bypass cybersecurity measures, developing innovative methods to steal user credentials. Hybrid password attacks merge multiple cracking techniques to amplify their effectiveness. These combined approaches exploit the strengths of various methods, accelerating the password-cracking process.  In this post, we'll explore hybrid attacks — what they are and the most common types. We'll also discuss how your organization can defend against them. The blended approach of hybrid attacks Threat actors are always looking for better, more successful ways to crack passwords — and hybrid attacks allow them to combine two different hacking techniques into a single attack. By integrating attack methodologies, they can take advantage of the strengths associated with each method, increasing their chances of success. And hybrid attacks aren't just limited to cracking passwords. Cybercriminals regularly combine technical cyberattacks with other tactics, ...

Cybersecurity researchers have shed light on a new digital skimmer campaign that leverages Unicode obfuscation techniques to conceal a skimmer dubbed Mongolian Skimmer. "At first glance, the thing that stood out was the script's obfuscation, which seemed a bit bizarre because of all the accented characters," Jscrambler researchers said in an analysis. "The heavy use of Unicode characters, many of them invisible, does make the code very hard to read for humans." The script, at its core, has been found to leverage JavaScript's capability to use any Unicode character in identifiers to hide the malicious functionality. The end goal of the malware is to steal sensitive data entered on e-commerce checkout or admin pages, including financial information, which are then exfiltrated to an attacker-controlled server. The skimmer, which typically manifests in the form of an inline script on compromised sites that fetches the actual payload from an external serv...

Ivanti has warned that three new security vulnerabilities impacting its Cloud Service Appliance (CSA) have come under active exploitation in the wild. The zero-day flaws are being weaponized in conjunction with another flaw in CSA that the company patched last month, the Utah-based software services provider said. Successful exploitation of these vulnerabilities could allow an authenticated attacker with admin privileges to bypass restrictions, run arbitrary SQL statements, or obtain remote code execution. "We are aware of a limited number of customers running CSA 4.6 patch 518 and prior who have been exploited when CVE-2024-9379, CVE-2024-9380, or CVE-2024-9381 are chained with CVE-2024-8963," the company said . There is no evidence of exploitation against customer environments running CSA 5.0. A brief description of the three shortcomings is as follows - CVE-2024-9379 (CVSS score: 6.5) - SQL injection in the admin web console of Ivanti CSA before version 5.0.2 all...

Ukraine has claimed responsibility for a cyber attack that targeted Russia state media company VGTRK and disrupted its operations, according to reports from Bloomberg and Reuters .

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,...

A previously undocumented threat actor called CeranaKeeper has been linked to a string of data exfiltration attacks targeting Southeast Asia. Slovak cybersecurity firm ESET, which observed campaigns targeting governmental institutions in Thailand starting in 2023, attributed the activity cluster as aligned to China, leveraging tools previously identified as used by the Mustang Panda actor. "The group constantly updates its backdoor to evade detection and diversifies its methods to aid massive data exfiltration," security researcher Romain Dumont said in an analysis published today. "CeranaKeeper abuses popular, legitimate cloud and file-sharing services such as Dropbox and OneDrive to implement custom backdoors and extraction tools." Some of the other countries targeted by the adversary include Myanmar, the Philippines, Japan, and Taiwan, all of which have been targeted by Chinese state-sponsored threat actors in recent years. ESET described CeranaKeeper a...
