TWCERT warns of phishing campaigns abusing Microsoft 365, lookalike domains, and short-lived SSL certificates to evade defenses

May 13, 2026

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 CERT warns of “Operation WrtHug” targeting ASUS routers via AiCloud command-injection flaws

May 13, 2026

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 CERT warns WSUS RCE CVE-2025-59287 (CVSS 9.8) is under active exploitation

May 13, 2026

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.
