各位师生同仁您好：

近期校内发生多起钓鱼信件攻击，有外部有心人士假冒校内主管名义发送电子邮件。
該類詐騙信件會使用免費電子郵件信箱偽裝成首長，並以「工作安排」、「後續業務聯繫」等公務需求為由，誘騙同仁協助建立 LINE 工作群組並回傳群組 QR Code，藉此進行後續詐騙或不當意圖。

请全校师生务必提高警觉，收到长官或同事交办事项之信件时，切勿仅凭信件显示的「寄件者名称」就轻信，务必点开并检查「实际寄件者电子邮件地址」是否為学校官方信箱。若收到来源不明或内容可疑之讯息，请勿回信、点击连结、下载档案、或依指示建立通讯软体群组。如有疑虑，请先透过校内分机或其他官方管道向当事人确认讯息真偽。

资讯中心提醒您：
1.仔細核對寄件者信箱：確認信件來源為學校官方網域，而非假冒長官名義的免費外部信箱（如 Gmail、Yahoo 等）。
2.勿輕易建立或加入不明群組：對於要求私下加 LINE、建立工作群組或回傳 QR Code 的要求，應提高警覺並向當事人二次查證。
3.切勿提供敏感资讯：勿任意提供帐号、密码、验证码或金融帐户等资讯。

敬请大家共同提高资安警觉，维护校园资讯安全。

Dear Faculty, Staff, and Students:

Recently, there have been multiple phishing attacks targeting the campus, involving malicious external actors who impersonate university administrators to send emails.
These fraudulent emails often use free email accounts to masquerade as senior officials. Citing official business needs—such as "work arrangements" or "follow-up coordination"—they trick recipients into creating LINE work groups and sharing the group's QR code, thereby facilitating further scams or malicious activities.

We urge all faculty, staff, and students to remain vigilant. When receiving emails regarding tasks assigned by supervisors or colleagues, do not rely solely on the displayed "Sender Name." You must open the email details to verify that the "Actual Sender's Email Address" belongs to an official university domain. If you receive messages from unknown sources or with suspicious content, do not reply, click links, download files, or create messaging app groups as instructed. If in doubt, please verify the message's authenticity with the alleged sender via campus extensions or other official channels.

The Information Center reminds you to:
1. Carefully verify the sender's email address: Ensure the email originates from an official university domain rather than a free external account (e.g., Gmail, Yahoo) impersonating a senior official.
2. Do not hastily create or join unknown groups: Be wary of requests to connect privately on LINE, set up work groups, or share QR codes; always double-check such requests with the person involved.
3. Never disclose sensitive information: Do not share account details, passwords, verification codes, or financial account information.

Let us work together to heighten cybersecurity awareness and safeguard our campus information security.
