The U.S. Cybersecurity and Infrastructure Security Agency (CISA), along with the Coast Guard Cyber Command (CGCYBER), on Thursday released a joint advisory warning of continued attempts on the part of threat actors to exploit the Log4Shell flaw in VMware Horizon servers to breach target networks. "Since December 2021, multiple threat actor groups have exploited Log4Shell on unpatched, public-facing VMware Horizon and [Unified Access Gateway] servers," the agencies  said . "As part of this exploitation, suspected APT actors implanted loader malware on compromised systems with embedded executables enabling remote command-and-control (C2)." In one instance, the adversary is said to have been able to move laterally inside the victim network, obtain access to a disaster recovery network, and collect and exfiltrate sensitive law enforcement data. Log4Shell , tracked as  CVE-2021-44228  (CVSS score: 10.0), is a remote code execution vulnerability affecting the Apache ...

The beleaguered Israeli surveillanceware vendor NSO Group this week admitted to the European Union lawmakers that its Pegasus tool was used by at least five countries in the region. "We're trying to do the right thing and that's more than other companies working in the industry," Chaim Gelfand, the company's general counsel and chief compliance officer, said, according to a  report  from Politico. Acknowledging that it had "made mistakes," the company also stressed on the need for an international standard to regulate the government use of spyware. The disclosure comes as a special inquiry committee was  launched in April 2022  to investigate alleged breaches of E.U. law following revelations that the company's Pegasus spyware is being used to snoop on phones belonging to politicians, diplomats, and civil society members. "The committee is going to look into existing national laws regulating surveillance, and whether Pegasus spyware was us...

When it comes to keeping SaaS stacks secure, IT and security teams need to be able to streamline the detection and remediation of misconfigurations in order to best protect their SaaS stack from threats. However, while companies adopt more and more apps, their increase in SaaS security tools and staff has lagged behind, as found in the  2022 SaaS Security Survey Report.  The survey report, completed by Adaptive Shield in conjunction with Cloud Security Alliance (CSA), dives into how CISOs today are managing the growing SaaS app attack surface and the steps they are taking to secure their organizations.  The report finds that at least 43% of organizations have experienced a security incident as a result of a SaaS misconfiguration; however, with another 20% being "unsure," the real number could be  as high as 63% . These numbers are particularly striking when compared to the 17% of organizations experiencing security incidents due to an IaaS misconfiguration.  ...

A threat cluster with ties to a hacking group called Tropic Trooper has been spotted using a previously undocumented malware coded in Nim language to strike targets as part of a newly discovered campaign. The novel loader, dubbed Nimbda, is "bundled with a Chinese language greyware 'SMS Bomber' tool that is most likely illegally distributed in the Chinese-speaking web," Israeli cybersecurity company Check Point  said  in a report. "Whoever crafted the Nim loader took special care to give it the same executable icon as the SMS Bomber that it drops and executes," the researchers said. "Therefore the entire bundle works as a trojanized binary." SMS Bomber, as the name indicates, allows a user to input a phone number (not their own) so as to flood the victim's device with messages and potentially render it unusable in what's a denial-of-service (DoS) attack. The fact that the binary doubles up as SMS Bomber and a backdoor suggests that t...

QNAP, Taiwanese maker of network-attached storage (NAS) devices, on Wednesday said it's in the process of fixing a critical three-year-old PHP vulnerability that could be abused to achieve remote code execution. "A vulnerability has been reported to affect PHP versions 7.1.x below 7.1.33, 7.2.x below 7.2.24, and 7.3.x below 7.3.11 with improper nginx config," the hardware vendor  said  in an advisory. "If exploited, the vulnerability allows attackers to gain remote code execution." The vulnerability, tracked as  CVE-2019-11043 , is rated 9.8 out of 10 for severity on the CVSS vulnerability scoring system. That said, it's required that Nginx and php-fpm are running in appliances using the following QNAP operating system versions - QTS 5.0.x and later QTS 4.5.x and later QuTS hero h5.0.x and later QuTS hero h4.5.x and later QuTScloud c5.0.x and later "As QTS, QuTS hero or QuTScloud does not have nginx installed by default, QNAP NAS are not aff...

A new piece of research from academics at ETH Zurich has identified a number of critical security issues in the MEGA cloud storage service that could be leveraged to break the confidentiality and integrity of user data. In a paper titled " MEGA: Malleable Encryption Goes Awry ," the researchers point out how MEGA's system does not protect its users against a malicious server, thereby enabling a rogue actor to fully compromise the privacy of the uploaded files. "Additionally, the integrity of user data is damaged to the extent that an attacker can insert malicious files of their choice which pass all authenticity checks of the client," ETH Zurich's Matilda Backendal, Miro Haller, and Kenneth G. Paterson said in an analysis of the service's cryptographic architecture. MEGA, which  advertises  itself as the "privacy company" and claims to provide user-controlled end-to-end encrypted cloud storage, has more than 10 million daily active users, w...

The Computer Emergency Response Team of Ukraine (CERT-UA) has  cautioned  of a new set of spear-phishing attacks exploiting the "Follina" flaw in the Windows operating system to deploy password-stealing malware. Attributing the intrusions to a Russian nation-state group tracked as APT28 (aka Fancy Bear or Sofacy), the agency said the attacks commence with a lure document titled "Nuclear Terrorism A Very Real Threat.rtf" that, when opened, exploits the recently disclosed vulnerability to download and execute a malware called CredoMap. Follina ( CVE-2022-30190 , CVSS score: 7.8), which concerns a case of remote code execution affecting the Windows Support Diagnostic Tool (MSDT), was addressed by Microsoft on June 14, as part of its Patch Tuesday updates , but not before it was subjected to widespread zero-day exploit activity by numerous threat actors. According to an independent report published by Malwarebytes,  CredoMap  is a variant of the .NET-based credenti...
