HealthEquity is offering two years of free credit monitoring and advising affected individuals to watch for suspicious activity.
SolarWinds Legal Ruling Expected to Narrow, but Maintain SEC Oversight on Cyber Transparency
Source: Cybersecurity Dive
A federal court ruling in the SolarWinds civil fraud case has significant implications for cybersecurity risk disclosures. Judge Paul Engelmayer dismissed most charges against SolarWinds and its CISO, including claims related to internal accounting practices. However, he upheld a charge concerning the company's pre-IPO security statement. This decision maintains the SEC's ability to pursue fraud claims when public companies' cybersecurity representations don't align with internal reporting. As demonstrated by recent settlements and prosecutions, federal authorities continue to scrutinize firms for inadequate cybersecurity incident disclosures. The SolarWinds case is set for an initial pretrial conference on August 14, which will further test the limits of SEC enforcement in cybersecurity matters.
Casper Network Pauses Operations After Cyberattack: What You Need to Know
Source: The Cyber Express
Casper Network halted all operations following a cyberattack. The breach led to the freezing of transactions, including transfers, to protect user assets and maintain network integrity. Casper Network's team is working to resolve the issue and will release a post-mortem report and code updates on GitHub. While operations are paused, $CSPR trading continues on exchanges to maintain liquidity.
Proofpoint Email Routing Flaw Exploited to Send Millions of Spoofed Phishing Emails
Source: The Hacker News
A massive phishing scam exploited an email routing misconfiguration in Proofpoint's defenses and allowed a threat actor to send millions of spoofed emails from legitimate companies like Best Buy and IBM. This campaign leveraged authenticated SPF and DKIM signatures to bypass security protections and deceive recipients into divulging sensitive information. The attackers used a loophole in Proofpoint's servers to route messages through Microsoft 365 tenants and relay them via Proofpoint’s infrastructure. Although no customer data was exposed, Proofpoint has since implemented stricter controls and urged email service providers to limit bulk messaging capabilities to prevent similar exploits in the future.
US Border Agents Must Get Warrant Before Cell Phone Searches, Federal Court Rules
Source: TechCrunch
A federal court in New York ruled on July 24 that U.S. border agents must obtain a warrant before searching the electronic devices of Americans and international travelers. This decision challenges the long-standing practice of allowing warrantless device searches at U.S. ports of entry. The ruling reflects growing concerns about Fourth and First Amendment rights, including privacy and free speech. The decision could prompt further legal action or appeal.
Unveiling the Stargazer Goblin: A Closer Look at the Stargazers Ghost Network’s $100,000 Malware Operation
Source: The Cyber Express
Cybersecurity experts uncovered the Stargazers Ghost Network, a sophisticated $100,000 malware distribution scheme utilizing over 3,000 fake GitHub accounts. Operated by the threat actor “Stargazer Goblin,” the network uses these accounts to distribute information-stealing malware across thousands of repositories. The network's strategy involves using fake accounts to simulate normal user behavior and enhance the legitimacy of its malicious activities. It has affected over 1,300 victims in a single campaign and operates across multiple platforms, including Discord and YouTube.

Walmart Discovers New PowerShell Backdoor Linked to Zloader Malware
Source: Infosecurity Magazine
Walmart's Cyber Intelligence Team identified a new PowerShell backdoor associated with a variant of Zloader/SilentNight malware. This backdoor was uncovered during routine threat investigations and provides threat actors with access for reconnaissance and deploying additional malware. Using sophisticated obfuscation techniques, the backdoor evades detection by hiding its components and performing checks to avoid analysis. The malware has few detections on VirusTotal and is challenging to sandbox–reflecting a broader trend of advanced threat actors utilizing scripting languages for backdoor operations.
VULNERABILITIES TO WATCH
Millions of Websites Susceptible to XSS Attack via OAuth Implementation Flaw
Source: Security Week
Security researchers at Salt Labs uncovered a critical cross-site scripting (XSS) vulnerability affecting millions of websites worldwide due to flawed OAuth implementations. This widespread issue stems from developers' complacency with XSS mitigation and the ease of implementing OAuth for social logins. The vulnerability allows attackers to bypass existing XSS protections, potentially leading to complete account takeovers. High-profile sites like HotJar and Business Insider were found vulnerable, with HotJar's extensive data collection posing significant risks to user privacy. The attack exploits the OAuth redirect process, intercepting login secrets through crafted links and social engineering. To address this threat, Salt Labs released a free scanner for websites to check their OAuth implementations and urges developers to prioritize secure integration of social login features.
Threat Actors Exploiting OS Command Injection Flaws To Hack Systems, CISA Warns
Source: Cyber Security News
CISA warns that OS command injection flaws are being exploited by attackers to run unauthorized commands on systems–risking data theft, system compromise, and service disruption. These vulnerabilities arise from insufficient validation of user input which leads to potential remote code execution. CISA's alert emphasizes the need for secure-by-design practices, including input validation and the use of safe command functions. Key recommendations for software manufacturers include taking ownership of security outcomes, embracing transparency, and building strong organizational structures. Adhering to these practices from the design phase can prevent such vulnerabilities and improve overall product security.
RADIUS Protocol Vulnerability Impacted Multiple Cisco Products
Source: Cyber Security News
A critical vulnerability in the RADIUS protocol (CVE-2024-3596) affects various Cisco products by allowing attackers to forge RADIUS responses and potentially gain unauthorized network access. Disclosed on July 7, 2024, the flaw exploits MD5’s use in response authentication, enabling chosen-prefix collision attacks without needing the shared secret. Cisco's investigation revealed that products like ASA, Firepower, and Nexus series are vulnerable, while others are not. The company advises using TLS/DTLS encryption, network isolation, and software updates as mitigations. Other vendors are also assessing the vulnerability’s impact.
Hackers Exploiting MSHTML Vulnerability to Deliver Atlantida Malware
Source: Cyber Security News
A critical MSHTML vulnerability (CVE-2024-38112) is being exploited by the threat actor Void Banshee to spread the Atlantida InfoStealer malware. The attack targets users through seemingly innocent PDF books shared on public platforms like online libraries and Discord. Despite Internet Explorer's disabled status, attackers abuse its rendering engine via URL files to execute malicious code. Victims unknowingly download archives containing the stealer, which then pilfers sensitive data from various applications and browsers.?
SPECIAL REPORTS
Three Ways to Mitigate AI-Based Supply Chain Attacks
Source: SC Media
As AI tools increasingly enhance the speed and scale of supply chain attacks, organizations must adopt rigorous defense strategies. Recent incidents highlight how attackers exploit vulnerabilities in software and cloud dependencies, often targeting third-party suppliers to access broader networks. To mitigate these risks, companies should minimize third-party privileges, utilize the MITRE ATT&CK framework for detection validation, and enhance their analysis and testing processes. Despite ongoing efforts like SBOM and VEX guidance, companies must proactively manage their dependency risks to counteract sophisticated AI-driven threats.
