Ransomware is one of the most disruptive cybersecurity threats facing businesses today. A single successful attack can lock employees out of essential files, interrupt customer services, expose confidential information and bring business operations to a standstill.<\/p>\n
For a Zimbabwean business, the consequences can be particularly serious. Imagine arriving at the office on Monday morning only to discover that your accounting system is inaccessible, customer records have been encrypted, shared files will not open and a message is demanding payment in cryptocurrency to restore access.<\/p>\n
The problem is not limited to large corporations. Small businesses, schools, accounting firms, retail companies, hospitals and organisations that depend on computers and online services can all become targets.<\/p>\n
The good news is that ransomware risk can be reduced through sensible security measures, proper preparation and a tested recovery plan.<\/p>\n
In this guide, we explain how ransomware works, how businesses in Zimbabwe can protect themselves and what to do if an attack occurs.<\/p>\n
Ransomware is a type of malicious software that prevents an organisation from accessing its files, systems or devices. It commonly does this by encrypting data and demanding payment in exchange for a decryption key.<\/p>\n
However, modern ransomware attacks can involve more than locking files.<\/p>\n
Some attackers first gain access to a company’s network, steal confidential information, disable security controls and attempt to compromise backups. They may then encrypt systems and threaten to publish stolen information unless the organisation pays.<\/p>\n
This is sometimes called double extortion.<\/p>\n
For example, a business might discover that its customer database has been encrypted. Even if the company has a backup, the attackers may threaten to release copies of the stolen customer information.<\/p>\n
Ransomware is therefore both an availability problem and a potential data confidentiality incident.<\/p>\n
The New Zealand National Cyber Security Centre describes common ransomware attack stages as initial access, consolidation and preparation, followed by the impact on the target. This illustrates why businesses need several layers of protection rather than relying on a single security product.<\/p>\n
Understanding how attackers gain access is the first step towards preventing an incident.<\/p>\n
Phishing remains a common way of delivering malicious software or stealing employee credentials.<\/p>\n
An employee might receive an email that appears to come from a supplier, bank, customer or colleague. The message may contain an attachment, an invoice or a link asking the recipient to review a document.<\/p>\n
If the employee opens a malicious attachment or enters their login details on a fraudulent website, attackers may gain an opportunity to access the organisation’s systems.<\/p>\n
Attackers may use stolen credentials, password guessing or previously leaked passwords to access business accounts.<\/p>\n
If employees reuse passwords across different services, a password compromised on one platform could expose several other accounts.<\/p>\n
Administrative accounts are especially attractive because they may provide access to multiple computers, servers and business applications.<\/p>\n
Unpatched operating systems, applications, servers and internet-facing services can contain vulnerabilities that attackers exploit.<\/p>\n
A business may be running an older version of a remote access service, content management system or business application without realising that a security weakness has already been identified.<\/p>\n
Remote Desktop Protocol (RDP), VPN services and other remote access systems can become entry points when they are poorly configured or exposed to the internet without adequate protection.<\/p>\n
Businesses should identify which services are accessible externally and ensure that access is properly secured.<\/p>\n
An attacker who gains access to a business email account may use it to send convincing messages to employees, suppliers and customers.<\/p>\n
This can help the attacker spread malicious links, steal further credentials or obtain access to other business systems.<\/p>\n
The New Zealand NCSC’s ransomware guidance identifies phishing, password attacks and exploitation of vulnerabilities as common initial access methods. https:\/\/www.ncsc.govt.nz\/protect-your-organisation\/protect-your-organisation-against-ransomware\/<\/a><\/p>\n Preventing ransomware requires a combination of technology, good security practices and employee awareness. The following measures provide a practical starting point.<\/p>\n Backups are among the most important safeguards a business can have.<\/p>\n If ransomware encrypts your computers or servers, a clean and usable backup may allow you to restore operations without relying on the attackers.<\/p>\n However, simply having a backup is not enough.<\/p>\n Some ransomware operators deliberately search for accessible backup systems and attempt to delete or encrypt them before launching the final attack.<\/p>\n Businesses should therefore:<\/p>\n For example, a Harare-based accounting firm might back up its accounting database every day, retain additional weekly copies and keep a separate protected copy away from its main office network.<\/p>\n The company should also test whether it can actually restore the database. A backup that cannot be recovered when needed offers little practical protection.<\/p>\n The UK National Cyber Security Centre recommends maintaining regular backups, keeping offline copies and testing restoration procedures. https:\/\/www.ncsc.gov.uk\/guidance\/mitigating-malware-and-ransomware-attacks<\/a><\/p>\n Every laptop, desktop computer and server connected to your business network represents a potential entry point.<\/p>\n Traditional antivirus software can help identify known malicious files, but businesses should consider endpoint protection that offers broader threat detection and prevention capabilities.<\/p>\n Depending on the selected product, business endpoint security can help with:<\/p>\n Businesses can consider solutions such as ESET business security products, with the appropriate protection level selected for their environment.<\/p>\n Tremhost offers ESET security solutions for organisations looking to strengthen endpoint protection across their computers and devices.<\/p>\n Explore: https:\/\/tremhost.com\/eset-security<\/a><\/p>\n It is important to remember that endpoint protection is one layer of defence. It should work alongside backups, email security, access controls and system updates.<\/p>\n Email is one of the most important communication tools in a modern business, but it is also a common attack channel.<\/p>\n Employees regularly receive invoices, quotations, purchase orders, statements and attachments from external contacts. This creates opportunities for attackers to disguise malicious messages as legitimate business correspondence.<\/p>\n Businesses should introduce stronger email security controls that can help identify:<\/p>\n Staff should also be trained to verify unexpected payment instructions, especially when a supplier suddenly changes banking details.<\/p>\n For organisations using Microsoft 365, Google Workspace or supported hosted email services, additional email security can provide another layer of protection.<\/p>\n Tremhost Armor Mail is designed to help businesses strengthen email security through managed protection against threats such as phishing, impersonation and malicious attachments.<\/p>\n Learn more: https:\/\/tremhost.com\/armormail<\/a><\/p>\n A password alone should not be the only thing protecting important business accounts.<\/p>\n Multi-factor authentication (MFA) requires users to provide an additional verification method when signing in.<\/p>\n This may involve an authenticator application, a security key or another supported verification method.<\/p>\n Businesses should prioritise MFA for:<\/p>\n MFA can make it significantly harder for an attacker to access an account using only a stolen password.<\/p>\n Where possible, use phishing-resistant authentication methods, particularly for privileged accounts.<\/p>\n Software updates are not just about adding new features. Many updates fix security vulnerabilities that attackers may already be attempting to exploit.<\/p>\n Businesses should maintain an update schedule covering:<\/p>\n Internet-facing systems should receive particular attention because attackers can search for vulnerable services remotely.<\/p>\n An organisation should also know which devices and applications it owns. You cannot reliably secure systems that you do not know exist.<\/p>\n Where an update cannot be installed immediately, the business should assess the risk and introduce appropriate temporary controls.<\/p>\n Not every employee needs access to every business system.<\/p>\n If an ordinary user account becomes compromised and has extensive administrative permissions, an attacker may be able to cause significantly more damage.<\/p>\n The principle of least privilege means giving employees only the access necessary to perform their responsibilities.<\/p>\n For example:<\/p>\n Businesses should also remove access promptly when employees leave or change roles.<\/p>\n Limiting permissions can help prevent an attacker from moving easily from one compromised computer to other systems.<\/p>\n Businesses with employees working remotely, multiple offices or external IT providers need to pay attention to how people connect to internal systems.<\/p>\n Remote access should be restricted to authorised users and protected with MFA, appropriate device controls and monitoring.<\/p>\n Other useful measures include:<\/p>\n For example, a company with offices in Harare, Bulawayo and Mutare should not assume that every device on its internal network needs unrestricted access to every other device.<\/p>\n Network segmentation can limit how far an attacker can move if one computer is compromised.<\/p>\n Tremhost Armor Network and Armor Workforce address different parts of this challenge. Armor Network focuses on managed network security, while Armor Workforce focuses on controlling access to business applications and resources.<\/p>\n Explore:<\/p>\n Technology cannot prevent every mistake.<\/p>\n An employee may receive a convincing message from someone pretending to be a director, supplier or customer. Another may download an attachment without checking its source.<\/p>\n Security awareness training should therefore form part of the organisation’s cybersecurity programme.<\/p>\n Employees should know how to identify:<\/p>\n Businesses should create a simple reporting process so that employees can quickly alert the appropriate person when something appears suspicious.<\/p>\n The objective is not to blame employees for mistakes. It is to build a workplace where suspicious activity is reported early.<\/p>\n Ransomware does not always encrypt files immediately after an attacker gains access.<\/p>\n Attackers may spend time exploring a network, obtaining additional credentials, accessing sensitive files and preparing to compromise multiple systems.<\/p>\n Businesses should monitor for warning signs such as:<\/p>\n Monitoring and alerting can help an organisation identify suspicious behaviour before it develops into a major incident.<\/p>\n For businesses without an internal security team, managed cybersecurity services can help provide structured monitoring, investigation and response support.<\/p>\n Even well-protected organisations need to prepare for the possibility of a successful attack.<\/p>\n An incident response plan should identify who is responsible for making decisions, isolating affected systems, contacting technical support and communicating with employees and customers.<\/p>\n The plan should include:<\/p>\n Keep a copy of essential incident response information somewhere that would remain accessible if the company’s email and file-sharing systems became unavailable.<\/p>\n A plan should be tested periodically through practical exercises. Finding out that nobody knows how to restore the accounting system during an actual ransomware incident is an expensive way to discover a weakness.<\/p>\n If you suspect a ransomware attack, act quickly. Avoid making changes without understanding their potential impact, and involve qualified incident response professionals.<\/p>\n The following steps provide a starting point.<\/p>\n Disconnect suspected infected computers from the business network.<\/p>\n This may involve removing network cables or disabling Wi-Fi connections. The objective is to reduce the opportunity for the malware to spread to other devices and shared resources.<\/p>\n Do not immediately reconnect an affected device simply because it appears to be working again.<\/p>\n Notify the person or organisation responsible for your cybersecurity.<\/p>\n If your business has a managed security provider, contact them using a verified emergency contact method.<\/p>\n Avoid relying on the infected email account or potentially compromised communication channels.<\/p>\n Identify which devices, servers and accounts may have been affected.<\/p>\n Where necessary, isolate systems that could be compromised. Protect clean backup environments and ensure attackers cannot continue accessing administrative accounts.<\/p>\n A professional incident response team should help establish the scope of the compromise before systems are returned to service.<\/p>\n Keep ransom notes, suspicious emails, relevant logs and other incident information.<\/p>\n Do not rush to wipe every affected computer before appropriate technical assessment. Evidence may be important when determining how the attackers gained access, what information was exposed and whether the threat remains active.<\/p>\n Credentials used by compromised systems may need to be reset.<\/p>\n Prioritise privileged accounts and other critical services, but coordinate changes with the response team to avoid disrupting systems needed for investigation and recovery.<\/p>\n Determine whether the attackers accessed or copied confidential information.<\/p>\n This is particularly important where the business holds customer information, employee records, financial data or other personal information.<\/p>\n An attack involving encrypted files does not automatically prove that data was stolen. Equally, recovering encrypted files does not prove that confidential information was never accessed.<\/p>\n The investigation should establish what happened as far as reasonably possible.<\/p>\n Before restoring operations, confirm that the selected backups are not infected or otherwise compromised.<\/p>\n Affected systems may need to be rebuilt, patched and secured before data is restored.<\/p>\n Do not simply reconnect an infected computer to the network and assume the problem has disappeared.<\/p>\n If personal data has been compromised, the organisation should assess its reporting obligations under Zimbabwe’s applicable data protection legislation.<\/p>\n Under the Cyber and Data Protection framework, including Statutory Instrument 155 of 2024, a data controller is required to report personal data breaches to the Data Protection Authority within 24 hours of becoming aware of the breach. Where the breach is likely to create a high risk to individuals’ rights and freedoms, affected data subjects must also be informed within 72 hours.<\/p>\n The organisation should obtain appropriate legal and data protection advice to determine how the requirements apply to the particular incident.<\/p>\n Paying a ransom should not be treated as a guaranteed recovery strategy.<\/p>\n There is no assurance that criminals will provide a working decryption key, delete stolen information or stop targeting the organisation.<\/p>\n Payment may also fund further criminal activity.<\/p>\n The UK National Cyber Security Centre advises organisations against paying ransom demands because payment does not guarantee recovery and may leave systems compromised.<\/p>\n The better approach is to involve experienced incident response professionals, preserve evidence, assess the damage and work towards a safe recovery.<\/p>\n Reference: https:\/\/www.ncsc.gov.uk\/section\/respond-recover\/sole-ransomware-attack<\/a><\/p>\n Cybersecurity is not only about protecting computers. It is also about protecting the information entrusted to a business.<\/p>\n Zimbabwe’s Cyber and Data Protection Act [Chapter 12:07] establishes requirements relating to the processing and protection of personal data.<\/p>\n Statutory Instrument 155 of 2024 also sets out provisions concerning security measures and personal data breach notifications.<\/p>\n For organisations that process personal information, a ransomware incident may therefore create responsibilities beyond restoring access to files.<\/p>\n For example, consider a business that stores customer names, contact details, identification information and transaction records. If attackers gain access to this information during a ransomware incident, the organisation may need to assess whether a reportable personal data breach has occurred.<\/p>\n Businesses should maintain appropriate security measures, internal reporting procedures and incident records.<\/p>\n They should also understand their responsibilities as data controllers or processors.<\/p>\n Importantly, purchasing a cybersecurity product does not automatically make an organisation compliant with Zimbabwean data protection requirements. Compliance depends on the organisation’s actual data processing activities, security arrangements and legal obligations.<\/p>\n Relevant legislation and regulations:<\/p>\n The cost of ransomware protection depends on the size of the organisation, the number of employees, the devices being protected and the complexity of its IT infrastructure.<\/p>\n A small business with five employees will not necessarily need the same security architecture as a financial institution with several branches.<\/p>\n A practical cybersecurity budget should consider the following:<\/p>\n10 ways to protect your business from ransomware in Zimbabwe<\/h2>\n
