A new Go-based botnet has been spotted scanning and brute-forcing self-hosted websites using the WordPress content management system (CMS) to seize control of targeted systems. "This new brute forcer is part of a new campaign we have named GoTrim because it was written in Go and uses ':::trim:::' to split data communicated to and from the C2 server," Fortinet FortiGuard Labs researchers Eduardo Altares, Joie Salvio, and Roy Tay  said . The active campaign, observed since September 2022, utilizes a bot network to perform distributed brute-force attacks in an attempt to login to the targeted web server. A successful break-in is followed by the operator installing a downloader PHP script in the newly compromised host that, in turn, is designed to deploy the "bot client" from a hard-coded URL, effectively adding the machine to the growing network. In its present form, GoTrim does not have self-propagation capabilities of its own, nor can it distribute oth...

Microsoft on Tuesday disclosed it took steps to implement blocking protections and suspend accounts that were used to publish malicious drivers that were certified by its Windows Hardware Developer Program . The tech giant said its investigation revealed the activity was restricted to a number of developer program accounts and that no further compromise was detected. Cryptographically signing malware is concerning not least because it not only undermines a key security mechanism but also allows threat actors to subvert traditional detection methods and infiltrate target networks to perform highly privileged operations. The probe, Redmond stated, was initiated after it was notified of rogue drivers being used in post-exploitation efforts, including deploying ransomware, by cybersecurity firms Mandiant, SentinelOne, and Sophos on October 19, 2022. One notable aspect of these attacks was that the adversary had already obtained administrative privileges on compromised systems before ...

Protecting customer data is critical for any business accepting online payment information. The Payment Card Industry Data Security Standard (PCI DSS), created by leading credit card companies, establishes best practices for protecting consumers' information. By adhering to these standards, businesses can ensure that their customer's personal and financial information is secure.  The PCI DSS security standards apply to any business that processes, stores, or transmits credit card information. Failure to comply with the PCI DSS can result in costly fines and penalties from credit card companies. It can also lead to a loss of customer trust, which can be devastating for any business. PCI DSS 4.0 was released in March 2022 and will replace the current PCI DSS 3.2.1 standard in March 2025. That provides a three-year transition period for organizations to be compliant with 4.0. The latest version of the standard will bring a new focus to an overlooked yet critically important ar...

Tech giant Microsoft released its last set of monthly security updates for 2022 with  fixes for 49 vulnerabilities  across its software products. Of the 49 bugs, six are rated Critical, 40 are rated Important, and three are rated Moderate in severity. The updates are in addition to  24 vulnerabilities  that have been addressed in the Chromium-based Edge browser since the start of the month. December's Patch Tuesday plugs two zero-day vulnerabilities, one that's actively exploited and another issue that's listed as publicly disclosed at the time of release. The former relates to  CVE-2022-44698  (CVSS score: 5.4), one of the  three security bypass issues  in Windows SmartScreen that could be exploited by a malicious actor to evade mark of the web (MotW) protections. It's worth noting that this issue, in conjunction with  CVE-2022-41091  (CVSS score: 5.4), has been observed being exploited by Magniber ransomware actors to deliver rogu...

The U.S. National Security Agency (NSA) on Tuesday  said  a threat actor tracked as APT5 has been actively exploiting a zero-day flaw in Citrix Application Delivery Controller (ADC) and Gateway to take over affected systems. The critical remote code execution vulnerability, identified as  CVE-2022-27518 , could allow an unauthenticated attacker to execute commands remotely on vulnerable devices and seize control. Successful exploitation, however, requires that the Citrix ADC or Citrix Gateway appliance is configured as a SAML service provider (SP) or a SAML identity provider (IdP). The following supported versions of Citrix ADC and Citrix Gateway are affected by the vulnerability - Citrix ADC and Citrix Gateway 13.0 before 13.0-58.32 Citrix ADC and Citrix Gateway 12.1 before 12.1-65.25 Citrix ADC 12.1-FIPS before 12.1-55.291 Citrix ADC 12.1-NDcPP before 12.1-55.291 Citrix ADC and Citrix Gateway versions 13.1 are not impacted. The company also said there are no...

Apple on Tuesday rolled out security updates to iOS, iPadOS, macOS, tvOS, and Safari web browser to address a new zero-day vulnerability that could result in the execution of malicious code. Tracked as  CVE-2022-42856 , the issue has been described by the tech giant as a type confusion issue in the WebKit browser engine that could be triggered when processing specially crafted content, leading to arbitrary code execution. The company said it's "aware of a report that this issue may have been actively exploited against versions of iOS released before iOS 15.1." While details surrounding the exact nature of the attacks are unknown as yet, it's likely that it involved a case of social engineering or a watering hole to infect the devices when visiting a rogue or legitimate-but-compromised domain via the browser. It's worth noting that every third-party web browser that's available for iOS and iPadOS, including Google Chrome, Mozilla Firefox, and Microsoft Edg...
