A Chinese advanced persistent threat tracked as Deep Panda has been observed exploiting the  Log4Shell vulnerability  in VMware Horizon servers to deploy a backdoor and a novel rootkit on infected machines with the goal of stealing sensitive data. "The nature of targeting was opportunistic insofar that multiple infections in several countries and various sectors occurred on the same dates,"  said  Rotem Sde-Or and Eliran Voronovitch, researchers with Fortinet's FortiGuard Labs, in a report released this week. "The victims belong to the financial, academic, cosmetics, and travel industries." Deep Panda , also known by the monikers Shell Crew, KungFu Kittens, and Bronze Firestone, is said to have been active since at least 2010, with recent attacks "targeting legal firms for data exfiltration and technology providers for command-and-control infrastructure building,"  according  to Secureworks. Cybersecurity firm CrowdStrike, which assigned the panda...

Threat actor groups like Wizard Spider and Sandworm have been wreaking havoc over the past few years – developing and deploying cybercrime tools like Conti, Trickbot, and Ryuk ransomware. Most recently, Sandworm (suspected to be a Russian cyber-military unit) unleashed cyberattacks against Ukranian infrastructure targets. To ensure cybersecurity providers are battle ready, MITRE Engenuity uses real-world attack scenarios and tactics implemented by threat groups to test security vendors' capabilities to protect against threats – the MITRE ATT&CK Evaluation. Each vendor's detections and capabilities are assessed within the context of the  MITRE ATT&CK Framework. This year, they used the tactics seen in Wizard Spider and Sandworm's during their evaluation simulations. And MITRE Engenuity didn't go easy on these participating vendors. As mentioned before – the stakes are too high, and risk is growing. The 2022 results overview To think about it simply, this MITRE ATT&C...

The North Korean state-backed hacking crew, otherwise known as the  Lazarus Group , has been attributed to yet another financially motivated campaign that leverages a trojanized decentralized finance (DeFi) wallet app to distribute a fully-featured backdoor onto compromised Windows systems. The app, which is equipped with functionalities to save and manage a cryptocurrency wallet, is also designed to trigger the launch of the implant that can take control of the infected host. Russian cybersecurity firm Kaspersky  said  it first encountered the rogue application in mid-December 2021. The infection scheme initiated by the app also results in the deployment of the installer for a legitimate application, which gets overwritten with a trojanized version in an effort to cover its tracks. That said, the initial access avenue is unclear, although it's suspected to be a case of social engineering. The spawned malware, which masquerades as Google's Chrome web browser, subsequ...

Networking equipment maker Zyxel has pushed security updates for a critical vulnerability affecting some of its business firewall and VPN products that could enable an attacker to take control of the devices. "An authentication bypass vulnerability caused by the lack of a proper access control mechanism has been found in the CGI program of some firewall versions," the company  said  in an advisory published this week. "The flaw could allow an attacker to bypass the authentication and obtain administrative access to the device." The flaw has been assigned the identifier  CVE-2022-0342  and is rated 9.8 out of 10 for severity. Credited with reporting the bug are Alessandro Sgreccia from Tecnical Service Srl and Roberto Garcia H and Victor Garcia R from Innotec Security. The following Zyxel products are impacted – USG/ZyWALL running firmware versions ZLD V4.20 through ZLD V4.70 (fixed in ZLD V4.71) USG FLEX running firmware versions ZLD V4.50 through ZLD V5.20 ...

Apple on Thursday rolled out emergency patches to address two zero-day flaws in its  mobile  and  desktop operating systems  that it said may have been exploited in the wild. The shortcomings have been fixed as part of updates to iOS and iPadOS 15.4.1, macOS Monterey 12.3.1, tvOS 15.4.1, and watchOS 8.5.1. Both the vulnerabilities have been reported to Apple anonymously. Tracked as  CVE-2022-22675 , the issue has been described as an  out-of-bounds write  vulnerability in an audio and video decoding component called AppleAVD that could allow an application to execute arbitrary code with kernel privileges. Apple said the defect was resolved with improved bounds checking, adding it's aware that "this issue may have been actively exploited." The latest version of macOS Monterey, besides fixing CVE-2022-22675, also includes remediation for  CVE-2022-22674 , an  out-of-bounds read  issue in the Intel Graphics Driver module that could en...

The maintainers of Spring Framework have released an emergency patch to address a newly disclosed  remote code execution flaw  that, if successfully exploited, could allow an unauthenticated attacker to take control of a targeted system. Tracked as  CVE-2022-22965 , the high-severity flaw impacts Spring Framework versions 5.3.0 to 5.3.17, 5.2.0 to 5.2.19, and other older, unsupported versions. Users are recommended to upgrade to versions 5.3.18 or later and 5.2.20 or later. The Spring Framework is a Java framework that offers infrastructure support to develop web applications. "The vulnerability impacts Spring  MVC  [model–view–controller] and Spring WebFlux applications running on [Java Development Kit] 9+," Rossen Stoyanchev of Spring.io  said  in an advisory published Thursday. "The specific exploit requires the application to run on Tomcat as a WAR deployment. If the application is deployed as a Spring Boot executable jar, i.e., the default, ...

Three security vulnerabilities have been disclosed in the popular Wyze Cam devices that grant malicious actors to execute arbitrary code and access camera feeds as well as unauthorizedly read the SD cards, the latter of which remained unresolved for nearly three years after the initial discovery. The security flaws relate to an authentication bypass (CVE-2019-9564), a remote code execution bug stemming from a stack-based buffer overflow (CVE-2019-12266), and a case of unauthenticated access to the contents of the SD card (no CVE). Successful exploitation of the bypass vulnerability could allow an outside attacker to fully control the device, including disabling recording to the SD card and turning on/off the camera, not to mention chaining it with CVE-2019-12266 to view the live audio and video feeds. Romanian cybersecurity firm Bitdefender, which  discovered the shortcomings , said it reached out to the vendor way back in May 2019, following which Wyze released patches to fix...

Researchers have disclosed what they say is the first-ever Python-based ransomware strain specifically designed to target exposed Jupyter notebooks, a web-based interactive computing platform that allows editing and running programs via a browser. "The attackers gained initial access via misconfigured environments, then ran a ransomware script that encrypts every file on a given path on the server and deletes itself after execution to conceal the attack," Assaf Morag, a data analyst at Aqua Security,  said  in a report. The new ransomware sample, which the cloud security firm detected after it was trapped in one of its honeypot servers, is said to have been executed after the unnamed adversary gained access to the server and downloaded the necessary tools required to carry out the encryption process by opening a terminal. Aqua Security characterized the attack as "simple and straightforward," unlike other traditional ransomware-as-a-service (RaaS) schemes, add...
