The Good

Supply chain attacks continue to pose a significant threat across industry verticals. In an attempt to reduce such risks, the CISA has introduced a new Hardware Bill of Materials (HBOM) framework that would require hardware vendors to share information on all physical components used in their products. Moving on, the DHS has released a new four-year IT strategic plan to bolster the cyber workforce and security of software used across the department.

• The CISA introduced a new framework called the Hardware Bill of Materials (HBOM) to mitigate supply chain risks for hardware products. It is inspired and is meant to be a complement to SBOM, a framework that the CISA has been pushing to software vendors since the Log4Shell incident in late 2021. Under this new framework, hardware vendors are expected to produce an HBOM file that will contain information on all physical components used in their products.

• The DHS released its new IT strategic plan for fiscal years 2024 through 2028, which prioritizes including the DHS IT academy to upskill its workforce on cybersecurity, among other training. The plan also lays out to retire legacy systems and build modern, effective, and secure software across the department.

• Security firm Confiant worked with industry partners to take down the infrastructure of a threat actor named ScamClub. Active since 2018, the group has employed multiple browser zero-days and is believed to have made an estimated $8.5 million in the first half of the year alone.

• Researchers observed several instances where attackers used malicious software packages to steal information from developers. In one instance, attackers uploaded 45 packages on npm and PyPI repositories in order to steal sensitive data such as SSH keys. In another incident, hackers breached GitHub accounts to insert malicious code disguised as Dependabot contributions in an attempt to steal authentication secrets and passwords from developers.

New Threats

Talking about new threats, organizations have been warned of a new trend adopted by several ransomware operators. It involves the deployment of two ransomware simultaneously against an organization, ultimately leading to mixed data encryption, exfiltration, and financial losses in the form of ransom payments. Besides these, a new malware dubbed ZenRAT was discovered in the wild, targeting Windows systems. A new variant of Xenomorph Android trojan also surfaced in the threat landscape, enabling its operators to target banking customers across the U.S. and Portugal.

• The Budworm APT used a previously unseen variant of SysUpdate backdoor, known as SysUpdate DLL inicore_v2.3.30.dll, to target a Middle Eastern telecommunications organization and an Asian government. The malware provides attackers with various capabilities, such as capturing screenshots, command execution, and service manipulation.
• Malwarebytes shared details on a new malvertising campaign that uses Bing Chat to distribute malware.
