Lazarus Group 的 LinkedIn 策略：網路犯罪者偽裝成求職者

臭名昭著的北韓網路犯罪組織 Lazarus Group 透過在 LinkedIn 上冒充求職者，設計了一種新的攻擊媒介。他們主動與目標公司聯繫，將惡意程式碼作為編碼工作呈現，並在程式碼執行時獲得對敏感財務資訊和加密資產的後門存取權限。這種複雜的方法凸顯了增強網路安全措施的必要性，包括徹底的背景調查、外部驗證、沙箱環境、程式碼審查流程、EDR 系統和定期軟體更新。

Lazarus Group's LinkedIn Gambit: Unveiling the Cybercriminal's Disguise

Lazarus Group 的 LinkedIn 策略：揭開網路犯罪者的偽裝

In the ever-evolving landscape of cybersecurity, the Lazarus Group stands as a formidable adversary, its nefarious operations leaving a trail of compromised networks and stolen assets. Recent reports have revealed a chilling new tactic employed by this notorious cybercrime syndicate: masquerading as job seekers on LinkedIn to infiltrate unsuspecting companies.

在不斷發展的網路安全格局中，拉撒路集團是一個可怕的對手，其邪惡行動留下了一系列受損的網路和被盜的資產。最近的報告揭露了這個臭名昭著的網路犯罪集團採用了一種令人毛骨悚然的新策略：在 LinkedIn 上偽裝成求職者，滲透到毫無戒心的公司。

The LinkedIn Deception

LinkedIn 欺騙

Lazarus Group's modus operandi hinges on exploiting the trust inherent in professional networking platforms like LinkedIn. Their operatives meticulously craft LinkedIn profiles, posing as experienced computer programmers specializing in sought-after technologies like React and Blockchain. With meticulous precision, they target specific companies within the cryptocurrency industry, reaching out to potential victims with enticing job offers.

Lazarus Group 的運作方式取決於利用 LinkedIn 等專業網路平台固有的信任。他們的工作人員精心製作 LinkedIn 個人資料，冒充經驗豐富的電腦程式設計師，專門研究 React 和區塊鏈等熱門技術。他們以一絲不苟的精準度，針對加密貨幣行業內的特定公司，向潛在受害者提供誘人的工作機會。

Once initial contact is established, the attackers leverage the allure of promising coding work, directing their targets to review code repositories hosted on platforms like GitHub. Unbeknownst to the unsuspecting victims, these repositories harbor malicious code snippets, dormant until executed. Upon execution, the malicious code initiates a series of insidious actions designed to compromise the target's computer.

一旦建立了初步聯繫，攻擊者就會利用有前途的編碼工作的誘惑，引導他們的目標審查託管在 GitHub 等平台上的程式碼儲存庫。毫無戒心的受害者並不知道，這些儲存庫中隱藏著惡意程式碼片段，在執行前一直處於休眠狀態。執行後，惡意程式碼會啟動一系列旨在危害目標電腦的陰險操作。

The Breach Aftermath

違規後果

The successful execution of Lazarus Group's LinkedIn attack provides the attackers with a virtual backdoor into the target's network, granting them access to sensitive financial information, crypto assets, and other valuable corporate resources. The consequences of such a breach are far-reaching, potentially resulting in substantial financial losses, theft of sensitive information, and irreparable damage to the company's reputation and trust.

Lazarus Group 的 LinkedIn 攻擊的成功執行為攻擊者提供了進入目標網路的虛擬後門，使他們能夠存取敏感的財務資訊、加密資產和其他有價值的企業資源。此類違規行為的後果是深遠的，可能會導致重大財務損失、敏感資訊被盜以及對公司聲譽和信任造成不可挽回的損害。

Thwarting the Cyber Threat

阻止網路威脅

To combat Lazarus Group's sophisticated attack tactics, organizations must adopt a multifaceted approach to cybersecurity, incorporating robust strategies and employing advanced technologies.

為了對抗 Lazarus Group 複雜的攻擊策略，組織必須採用多方面的網路安全方法，結合穩健的策略並採用先進的技術。

1. Enhanced Due Diligence:

1. 加強盡職調查：

Organizations should exercise extreme caution when evaluating new business contacts and job candidates, particularly those reaching out with unsolicited opportunities. Thoroughly vet potential hires through background checks, carefully examine company profiles on LinkedIn, and seek references to verify the legitimacy of the job offer.

組織在評估新的業務聯絡人和求職者時應格外謹慎，尤其是那些主動提供機會的人。透過背景調查徹底審查潛在員工，仔細檢查 LinkedIn 上的公司資料，並尋求參考資料以驗證工作機會的合法性。

2. External Validation:

2. 外部驗證：

When presented with job offers requiring access to code or documents, seek external validation and insights from trusted colleagues, industry contacts, or cybersecurity experts. These trusted sources can provide valuable perspectives on the legitimacy of the offer and potential red flags.

當收到需要存取程式碼或文件的工作機會時，請向值得信賴的同事、行業聯絡人或網路安全專家尋求外部驗證和見解。這些值得信賴的來源可以就要約的合法性和潛在的危險信號提供有價值的觀點。

3. Sandbox Environments:

3. 沙箱環境：

To mitigate the risk associated with executing unfamiliar code, organizations should utilize sandbox environments. These isolated environments allow potentially malicious code to be executed without jeopardizing the integrity of the organization's main network. By identifying and quarantining suspicious activities within the sandbox, organizations can proactively prevent breaches.

為了減輕與執行不熟悉的程式碼相關的風險，組織應該利用沙箱環境。這些隔離的環境允許執行潛在的惡意程式碼，而不會危及組織主網路的完整性。透過識別和隔離沙箱內的可疑活動，組織可以主動防止違規行為。

4. Code Review Processes:

4. 程式碼審查流程：

Organizations should establish mandatory code review processes, involving multiple team members, before allowing any external code to be executed within their systems. These reviews serve as an additional layer of security, ensuring that any malicious code is identified and neutralized before it can cause harm.

在允許在其係統內執行任何外部程式碼之前，組織應建立強制的程式碼審查流程，涉及多個團隊成員。這些審查充當了額外的安全層，確保在任何惡意程式碼造成損害之前識別並消除它。

5. Endpoint Detection and Response (EDR) Systems:

5. 端點檢測與響應（EDR）系統：

EDR systems play a crucial role in detecting, isolating, and remediating suspicious activities within an organization's network. These advanced systems utilize machine learning algorithms and behavioral analysis to identify potential threats and respond swiftly to neutralize them.

EDR 系統在偵測、隔離和修復組織網路內的可疑活動方面發揮著至關重要的作用。這些先進的系統利用機器學習演算法和行為分析來識別潛在威脅並快速回應以消除它們。

6. Regular Software Updates and Patching:

6. 定期軟體更新和修補程式：

Regularly updating software, particularly browsers and security tools, with the latest security patches is essential to prevent attackers from exploiting known vulnerabilities. By promptly patching known security holes, organizations can significantly reduce the risk of successful cyber-attacks.

使用最新的安全性修補程式定期更新軟體，特別是瀏覽器和安全工具，對於防止攻擊者利用已知漏洞至關重要。透過及時修補已知的安全漏洞，組織可以顯著降低網路攻擊成功的風險。

Conclusion

結論

Lazarus Group's LinkedIn attacks serve as a stark reminder of the ever-present threat posed by cybercriminals and the importance of robust cybersecurity practices. By implementing a comprehensive cybersecurity strategy that incorporates enhanced due diligence, external validation, sandbox environments, code review processes, EDR systems, and regular software updates, organizations can significantly reduce the risk of falling victim to these sophisticated attacks.

Lazarus Group 的 LinkedIn 攻擊清楚地提醒人們網路犯罪者所構成的威脅始終存在，以及強而有力的網路安全實踐的重要性。透過實施全面的網路安全策略，其中包括增強的盡職調查、外部驗證、沙箱環境、程式碼審查流程、EDR 系統和定期軟體更新，組織可以顯著降低成為這些複雜攻擊受害者的風險。
