警惕!2025年五大加密詐騙手法

5個「隱秘」加密貨幣詐騙需提防

隨著加密貨幣使用者面對越來越多的「心理操控」攻擊,黑客們也想出了更高明的手法來竊取資金,這是來自區塊鏈安全公司SlowMist的警告。

SlowMist的運營主管Lisa在該公司第二季度的《MistTrack被盜資金分析報告》中表示,儘管黑客的技術並沒有顯著進步,但詐騙手法卻變得更加精密,包括假冒瀏覽器擴展、被篡改的硬件錢包和社交工程攻擊。

“回顧第二季度,有一個明顯的趨勢:攻擊者的方法可能沒有在技術上變得更先進,但他們變得更加心理操控。”

“我們看到從純粹的鏈上攻擊轉向鏈下的入侵點——瀏覽器擴展、社交媒體賬號、身份驗證流程和用戶行為都成為了常見的攻擊面。”Lisa說。

惡意瀏覽器擴展假裝是安全插件

諷刺的是,一種新興的攻擊手法涉及到假冒安全插件的瀏覽器擴展,例如“Osiris”Chrome擴展,該擴展聲稱能檢測釣魚鏈接和可疑網站。

然而,這個擴展實際上會攔截所有.exe、.dmg和.zip文件的下載,並將這些文件替換為惡意程序。

“更隱秘的是,攻擊者會引導用戶訪問一些知名且常用的網站,例如Notion或Zoom,”Lisa說。

“當用戶試圖從這些官方網站下載軟件時,實際交付的文件已經被惡意替換——但瀏覽器仍然顯示下載來自合法來源,讓用戶幾乎無法察覺任何可疑之處。”

這些程序會收集用戶計算機上的敏感信息,包括Chrome瀏覽器數據和macOS Keychain憑證,從而使攻擊者能夠訪問種子短語、私鑰或登錄憑證。

攻擊利用加密貨幣用戶的焦慮

SlowMist還指出,另一種攻擊手法是欺騙加密貨幣投資者使用被篡改的硬件錢包。

在某些情況下,黑客會向用戶發送一個受損的冷錢包,告訴受害者他們在“抽獎中”贏得了免費設備,或者告訴他們現有設備已被攻擊,需要轉移資產。

在第二季度,一名受害者報告稱因購買了一個在TikTok上看到的被篡改冷錢包而損失了650萬美元。

另一名攻擊者則出售了一個已被預先激活的硬件錢包,讓他們能在新用戶將加密貨幣轉入儲存後立即排空資金。

社交工程與假冒撤銷網站

SlowMist還在第二季度接到一名用戶的求助,該用戶無法撤銷其錢包中的“風險授權”。

經調查,SlowMist發現用戶試圖撤銷智能合約權限的網站是一個“幾乎完美複製”流行的Revoke Cash界面的網站,該網站要求用戶輸入私鑰以“檢查風險簽名”。

“經過分析前端代碼,我們確認這個釣魚網站使用EmailJS將用戶的輸入——包括私鑰和地址——發送到攻擊者的電子郵件收件箱。”

“這些社交工程攻擊在技術上並不複雜,但它們擅長利用緊迫感和信任,”Lisa說。

“攻擊者知道像‘檢測到風險簽名’這樣的短語會引發恐慌,促使用戶採取匆忙的行動。一旦觸發這種情緒狀態,操控他們做出平時不會做的事情就變得容易了——例如點擊鏈接或分享敏感信息。”

攻擊利用Pectra升級、微信好友

其他攻擊還包括利用以太坊最新Pectra升級中引入的EIP-7702的釣魚技術,還有針對多名微信用戶的攻擊,通過控制他們的賬號來進行詐騙。

SlowMist的第二季度數據來自429份提交的被盜資金報告。該公司表示,已凍結並追回約1200萬美元,這些資金來自11名報告稱在第二季度遭到加密貨幣盜竊的受害者。

這些詐騙手法的演變顯示出黑客們不斷適應並利用人們的心理,這提醒我們在數字世界中保持警惕。隨著技術的進步,詐騙手法也在不斷演變,這意味著用戶需要更加謹慎,並提高自身的安全意識,以防止成為下一個受害者。

A captivating portrait of a young Asian woman, inspired by Imada Mio and embodying an exquisitely delicate, doll-like (精緻洋娃娃臉) aesthetic. She has large, round, expressive eyes that radiate innocence and curiosity, subtly accented with a moist shimmer. Her petite V-line face is framed by soft, rosy cheeks, and her lips are naturally pink and slightly parted, exuding an energetic, slightly flirty, yet pure aura. Her expression is a candid blend of sweetness and playful allure.

Her long, dark brown hair is artfully tousled with a messy morning (剛睡醒的凌亂感) effect—loose strands fall gently around her face, conveying natural volume and effortless beauty. The hair has a silky texture, catching the light in places, suggesting a recent awakening.

She is dressed in an oversized, translucent white button-down shirt (男友風白襯衫) with the top buttons casually undone, delicately revealing her collarbones and a slender neckline. The shirt drapes loosely, giving a tasteful "bottomless" look (下衣失蹤風格), her bare legs just barely visible beneath the shirt's hem, enhancing the innocent-meets-sensual ambiance.

The composition is styled in the manner of a Japanese Gravure Photobook (寫真集風格), exuding a pure & sexy vibe with an airy, dreamy atmosphere. Employ bright, high-key lighting for a clean, luminous effect that highlights her velvety soft skin texture. Use Fujifilm PRO 400H film tones for subtle pastel hues, gentle contrast, and a seamless blend of natural colors, further enriching the soft, ethereal, and intimate photographic quality.

The background is minimalist and softly blurred, ensuring complete focus on the subject, and enhancing the overall sense of warmth, comfort, and inviting allure typical of high-end Japanese photobooks.

Maintain 100% accuracy of the facial features — do not alter or modify any aspect of the face. Render the skin texture, lighting, and overall composition with photo-realistic detail, ensuring lifelike color tones and natural depth of field. A man with his original hair is sitting casually on a white cube, smiling warmly at the camera. He is wearing a cream-colored cable-knit sweater, blue jeans, and brown loafers. His legs are crossed, with one hand resting on his knee.
The background reveals a cozy and festive living room. A large, beautifully decorated Christmas tree with numerous warm lights and gold ornaments stands prominently behind him. Several wrapped gift boxes are visible at the base of the tree. To his left, another smaller decorated Christmas tree and a wreath on the wall further enhance the holiday atmosphere. The lighting is soft and inviting, creating a warm and welcoming scene. A beautiful young woman in her early twenties from Hong Kong has flawless, fair skin with a subtle glow. She possesses large, clear eyes with soft eyeliner and long, delicate eyelashes. Her nose is straight, and her face is exquisitely heart-shaped. Her lips are naturally pink. She has long, layered, dark brown hair parted in the middle. She wears a loose-fitting light gray and beige striped knit sweater with a waffle pattern and slightly oversized ribbed cuffs. One shoulder of the sweater slips slightly. She pairs this with a burgundy high-waisted quilted mini skirt with a diamond pattern and ruffles at the hem, revealing her long, smooth legs. She strikes a playful pose, her eyes innocent yet subtly alluring. She stands in front of a pristine white studio backdrop, the soft, even lighting creating a natural atmosphere without harsh shadows. This is a high-key portrait; the minimalist background highlights her delicate skin texture, and her sharp, clear eyes, presenting a realistic sense of style.
