web crawler 在 Facebook 的最佳貼文

方保僑則指，是次事件性質嚴重，反映淘寶系統有漏洞，雖近12億條用戶數據中，部份或屬同一用戶，但外洩數據量龐大仍不容忽視。他又提醒，個人資訊「潑出去就收唔返」，騙徒可據所獲資料行騙，近期不少騙案中，騙徒能精準道出事主電話號碼、姓名、電郵等資料博取信任。

web crawler 在 Facebook 的精選貼文

2021-05-02 08:33:42 有 15 人按讚

香港資訊科技商會榮譽會長方保僑說：「Facebook在2019年洩漏了5億用戶資料，其中包括300多萬香港用戶的資料。」近期的黑客將用戶資料上載到網上，當中大部份包括電話號碼及電郵。

以往網上騙徒多數都是靠碰運氣，程序員寫一個程式，順着電話號碼次序，將欺詐內容在各個通訊軟件傳出去，看看誰會中招，但現時配合黑客上載了的5億外洩資料，就比以前更容易撞中已登記使用的電話號碼。

當中最弔詭的是，部份假冒銀行或海關職員的騙徒能說出電話使用者的資料，成功博取信任，「很多騙案的開場白內容，都是取自社交媒體，甚至是從信箱偷取信件攫取資料，近期更發展至網頁抓取（Web scraping）。」所謂網頁抓取，即騙徒或程式員寫了一些網頁爬蟲（web crawler）程式，程式會從fb上公開的個人檔案中慢慢「爬出」名字、性別以及電郵等個人資料。「我今早才收到甚麼皇朝網上賭場的訊息，大家不要打開那些連結。」方保僑警告，無論這些網上賭場存在與否，如果貪好奇點進連結，可能會誤中病毒或木馬程式，就算該網上賭場真的存在，亦可能是一個騙局，因為遊戲運作的背後，都是由人為程式所控制，最簡單的解決方法就是封鎖對方後再刪除對話。

社交媒體和網頁抓取

近期多家大型社交媒體先後發生了用戶資料外洩事件，繼Facebook於2019年被黑客盜取逾5億名客戶資料後，早前跨國求職網站LinkedIn亦爆出大規模用戶數據外洩，約5億名用家的姓名、電郵、電話號碼等資料被竊；語音社交平台Clubhouse的130萬名客戶資料被上載到一個黑客論壇。

不過，上述幾間科技企業均異口同聲否認旗下網絡系統遭黑客攻陷，且強調沒有洩漏賬號密碼或信用卡資料等，那麼，黑客究竟從何取得相關的用戶資料呢？

社交媒體本來就是一個讓朋友經由網絡互相認識的平台，因此在大家開始使用之際，往往會先把一些個人基本資料放到社交媒體上，不僅可以讓公眾瀏覽，最主要目的是讓朋友有機會藉不同條件與你取得聯繫。

昔日黑客活動還沒有那麼頻繁的時候，網民會隨便把個人資料，除真實名字外，其餘包括性別、電話號碼、電郵地址、出生日期等，全放到社交媒體的個人檔案供別人索閱。事實上，只要用搜尋引擎查找一下，往往能尋出朋友在社交媒體上的賬號或一些公開資訊；而黑客正是運用類似技術來進行「網頁抓取」（web scraping）活動，即是透過「網頁爬蟲」（web crawler）從網絡大量抓取不同用戶的資料，然後結集成一個巨大的資料庫。當大家看到社交媒體外洩的個人資料居然數以億計，就應明白不能小覷網頁抓取的能耐。

儘管個別社交媒體否認網頁抓取是漏洞，並強調客戶資料未有遭黑客盜取；不過，也有社交媒體因應事件作出補救修正。至於社交網用戶可以做的事，除了更改密碼和加設「雙重認證」登入，更關鍵是須改變社交媒體上個人賬號內的私隱設定，譬如把一些沒有需要公開的資料隱藏甚至刪除，包括出生日期、電話號碼或電郵等，避免這些資料無遮掩地暴露在互聯網上，讓黑客能隨意抓取並利用該些資料來攻擊你的互聯網賬號，以至盜取其他程式或電子郵箱等，令你蒙受更大損失，釀成「二次傷害」。
