TWCERT/CC published a critical vulnerability notice for NewSoftOA, an office automation product from NewSoft (力新國際). The issue, tracked as CVE-2026-5965 and TVN-202604008, is an OS command injection flaw with a CVSS 3.1 score of 9.8. TWCERT/CC recommends upgrading to NewSoftOA 10.1.8.3 or later to address the risk.

Taiwan’s national CERT (TWCERT/CC) reports an active social-engineering campaign that combines legitimate Microsoft 365 email accounts, near-typosquat domains, and short-term SSL certificates to bypass email and web defenses. The activity includes two waves: (1) broad phishing emails themed as “Microsoft account abnormal sign-in activity” and (2) targeted spear-phishing that repeatedly sends “Microsoft one-time code” lures to create urgency before delivering an “abnormal sign-in” message. A notable tactic described by TWCERT is URL-pattern-based gating: victims who match attacker-defined URL rules see a customized phishing page that harvests credentials, while non-matching visitors are redirected to a legitimate login page—reducing detection and increasing credibility.

Taiwan’s TWCERT/CC issued an urgent alert citing SecurityScorecard’s STRIKE team research into “Operation WrtHug,” a sustained campaign targeting ASUS small office/home office routers worldwide. The activity is reported to abuse known, publicly disclosed OS command-injection vulnerabilities—including issues referenced alongside CVE-2023-39780—focused on the AiCloud service. TWCERT/CC says compromised routers may be backdoored and incorporated into a large global infected network used for follow-on cyber threat activity and espionage, with STRIKE reporting identification of more than 50,000 infected IP devices over the past six months. The advisory urges immediate firmware updates, replacement of end-of-life (EoL) models that cannot be patched, and consultation of ASUS product security advisories for official mitigation steps.

Taiwan’s TWCERT/CC is urging organizations to urgently patch a high-severity Windows Server Update Services (WSUS) vulnerability, CVE-2025-59287 (CVSS 9.8), after U.S. CISA added it to the Known Exploited Vulnerabilities (KEV) catalog and Dutch NCSC-NL also confirmed real-world exploitation. The flaw enables unauthenticated remote code execution as SYSTEM via a deserialization trigger, but only impacts Windows Server systems where the WSUS server role is enabled. TWCERT/CC also cited Huntress reporting attacker scanning for exposed WSUS ports 8530/8531 and delivering malicious requests, with post-exploitation activity potentially involving PowerShell-based payload execution and data discovery/exfiltration.

Taiwan’s national CERT (TWCERT/CC) warns that attackers are increasingly using public blockchains as command-and-control (C2) infrastructure. The advisory highlights “EtherHide,” a technique first described by security researchers in October 2023, where adversaries store malicious commands or payload locations inside smart contracts. Malware (or malicious web scripts) can then query the chain for updated instructions, reducing the effectiveness of traditional controls like domain/IP blocking and traffic monitoring. TWCERT/CC also notes EtherHide is frequently chained with the “ClearFake” social-engineering pattern—fake system notifications or software update prompts—often delivered via compromised WordPress sites embedding malicious JavaScript. The combined flow uses Binance Smart Chain (BSC) smart contracts and read-only calls (e.g., eth_call) to retrieve attacker instructions without on-chain transaction fees, improving stealth and persistence.

Taiwan’s national CERT (TWCERT/CC) held its 2025 Taiwan Cybersecurity Incident Notification & Response Annual Conference on Dec. 3 under the theme “Build Secure Products, Connect a Trusted Defense Line.” Government leaders from the Ministry of Digital Affairs and the Administration for Cyber Security emphasized that product security is now tied to brand trust and global market access, citing AI, IoT, and smart manufacturing expansion—and noting that international rules increasingly treat product security as a supply-chain governance requirement. The event brought together major Taiwan and regional vendors and institutes (including ASUS, Zyxel, Delta Electronics, Synology, Panasonic Taiwan, Institute for Information Industry, and others) to share practices around AI-driven threats, vulnerability disclosure, and PSIRT governance—signals relevant to global security and infrastructure teams that rely on Taiwan-linked hardware, NAS, networking, and industrial components.

Taiwan’s TWCERT/CC warns that a high-risk MongoDB Server vulnerability, CVE-2025-14847 (CVSS v4: 8.7), is under active exploitation and can leak sensitive data from server memory. The issue—dubbed “MongoBleed” by researchers—stems from incorrect handling of the reported length of zlib-decompressed messages, which can cause uninitialized heap memory residues to be included in responses. TWCERT/CC notes that more than 87,000 internet-exposed MongoDB servers could be at risk, and that CISA added the CVE to its Known Exploited Vulnerabilities (KEV) catalog on 2025-12-29, signaling elevated urgency for enterprises and government agencies.

OpenSSF’s review of CVE-2024-3094 describes an intentionally inserted, obfuscated backdoor affecting xz/liblzma 5.6.0 and 5.6.1. The tampering was designed to land in specific Linux distribution build outputs—DEB/RPM packages for x86-64 built with gcc and the GNU linker—rather than appearing uniformly across all builds. Red Hat warned the issue could allow remote compromise via sshd authentication bypass, but OpenSSF notes exposure was limited because the impacted versions were largely confined to experimental or pre-release distro channels and were detected quickly through community oversight and coordinated distro response.

Okta’s root-cause report says a threat actor accessed files in its customer support case management system from Sept. 28 to Oct. 17, 2023, affecting 134 customers (under 1%). Some accessed files were HAR files containing session tokens, enabling session hijacking; Okta says tokens were used to hijack sessions for 5 customers. The incident stemmed from a support-system service account credential that was likely exposed after being saved to an employee’s personal Google account via Chrome sign-in on an Okta-managed laptop. Okta also disclosed a logging visibility gap that delayed identifying file downloads until an IP indicator was shared by BeyondTrust. Read more
Microsoft’s MSRC investigation into Storm-0558 concludes that operational errors likely allowed Microsoft Account (MSA) consumer signing key material to escape a secure token signing environment via a crash-dump/debug workflow, after which the actor (attributed by Microsoft as China-based) likely obtained it by compromising a Microsoft engineer’s corporate account with access to the debugging environment. A separate engineering failure—missing issuer/scope validation when mail systems relied on a common key metadata endpoint—meant a consumer key could be used to forge tokens accepted for enterprise email access. Microsoft says it has since corrected the race condition, improved key-material detection and credential scanning, and updated libraries to automate scope validation. Read more
