Wiper Attacks: Key Threats, Examples, and Best Practices

Cyber threats are evolving at a very high pace in today’s digital landscape which keeps organizations vigilant and proactive. In such threats, wiper attacks stand out as one insidious form of cybercrime. They specialize in wiping out data and disrupting operations. While its variants tend to bank on financial gains through encrypted hostage data, the purpose of wiper attacks is to destroy valuable information irretrievably. This destructive intent can cause significant damage to the concerned organizations, leaving them to face huge operational setbacks and recoveries.

The aftermath of wiper attacks is not only pure data loss but at times results in reputational damages, loss of customers’ trust, and monetary implications as well. Business impact can be severe since businesses face extended downtimes with loss of intellectual property and legal repercussions. The organizations, as well as the individuals, in today’s global network, must know how wiper attacks are carried out, what the effects would look like, and how to prevent them. That way, stakeholders are educated on how they can better prepare to fight off those risks created by the absolutely devastating cyber attacks.

Researchers at Fortinet recently analyzed attack data from the second half of 2022 and observed a startling 53% increase in threat actor use of disk wipers between the third and fourth quarters of the year. This article will explore the various aspects of wiper attacks, including their definition, historical examples, methods of operation, and best practices for prevention and recovery.

What are Wiper Attacks?

Wiper attacks are malicious cyber incidents involving malware specifically created to wipe data off a system. Data destruction could be as minor as deleting individual files, while major incidents would corrupt entire databases and completely render any critical information unusable. These attacks commonly target organizations operating in high-stakes industries so that they can create chaos, disrupt operations, and cause long-lasting damage. Such a blow might bring debilitating effects because losing important information would stop business processes, damage the customer’s trust, and provide difficulties of very large recovery dimensions.

What Makes Wiper Attacks So Dangerous?

The danger of wiper attacks lies in their ability to cause instant and permanent harm. Since important data is wiped, then attackers are likely to fully cripple the operations within an organization, slow down productivity, and cause costly downtime events. This is unlike ransomware, whose possibility might be regaining lost data via some financial payment, but the wiper attack seems to completely have this chance erased. This has a lot at stake in terms of integrity in relation to data and also disrupts business continuity since organizations would be unable to operate efficiently in the wake of such an attack. The psychological damage on employees and stakeholders, in addition to possible financial implications, makes wiper attacks especially menacing in the world of cybersecurity.

History of Notable Wiper Attacks

Understanding the history of notable wiper attacks is very illuminating in its outlines of evolution from when it started to become a growing threat to organizations. These incidents illustrate the devastating potential of the threat of wiper malware, and their accounts underline the requirement for strong cybersecurity measures. Below are some significant wiper attacks that have shaped the land of cybersecurity:

1. Shamoon (2012): This was one of the first and most known wiper attacks that focused on the state-owned oil company Saudi Aramco. In this incident, data on thousands of computers were destroyed. The malware spreads across the organization’s network rapidly to erase critical data and renders operational systems inoperable. Operations of the company experienced not just disruption but also big recovery efforts, rebuilding the whole IT infrastructure of the company. Such was the importance of Shamoon that it became a moment of consciousness in cybersecurity, and organizations realized that they could also suffer from similar hostile and damaging actions.
2. NotPetya (2017): Once disguised as ransomware, NotPetya quickly turned out to be one of the most destructive cyberattacks in history. Although it focused on companies in Ukraine with geopolitical tensions at the time, its destructive payload reached across the world, targeting companies in numerous countries. It indeed deleted data from many systems and rendered incapacitation in many organizations, thus causing billions in damages. This attack unleashed the malevolent capability of wiper malware to destroy infrastructure at a global level, targeting parts of critical infrastructure and tripping supply lines globally. Its aftermath has acted as a wake-up call for organizations across the globe about the extraordinary extent of cyber warfare.
3. WhisperGate (2022): As part of these geopolitical tensions, WhisperGate concentrated its attacks on Ukrainian organizations utilizing wiper malware which deletes sensitive information and critical services. Not only was the attack timely but also it had intent. In a period where conflict has heightened, these attacks using wiper malware do more than destroy data. They destroy public confidence and upend government operations. WhisperGate defined the areas in which cyber warfare relates to political confrontations. At these times, the wiper attacks are used as a tool for strategic, more general goals. The effect of the attack was a clear call for reinforced cybersecurity protection in the face of rapidly changing threats and international cooperation over its prevention.
4. Dustman (2019): Dustman was focused against Bahrain National Oil Company, overlaying files with random data on infected computers, effectively purging their information of principle that had links with Iranian state-sponsored threat actors. This indicates how nation-states may wield wiper malware as an influence or for economic disruption purposes. The critical sector targeted in the Dustman attack was oil production, and thus, it demonstrated the ability of wiper malware to disrupt critical services and underscored the geopolitical motivation for such cyber operations. In doing so, it vindicated the observation that organizations conducting businesses in critical infrastructure sectors have a reason to be constantly alert and perhaps more proactive concerning their cybersecurity posture in preventing all risks associated with state-sponsored attacks.

Wiper Attacks vs Ransomware

While both ransomware and wiper attacks can be brutal, they fundamentally work on different principles, and understanding the difference can play an important role for organizations as they develop their cybersecurity strategies.

• Ransomware: Ransomware is a type of malware that works by encrypting victim data so it cannot be accessed until a ransom is paid to the attacker. Ransomware is primarily a financially motivated attack that usually provides the decryption key when paid. Companies have a very tough decision: to pay the ransom and, hopefully, recover the data or not pay at all and risk permanent loss of data. While damaging and disruptive, ransomware attacks sometimes offer opportunities for retrieval through appropriate backups or even negotiation with the attackers.
• Wiper Attacks: A wiper attack is meant to irrevocably wipe or delete information, and recovery is not possible. In most cases, a wiper attack is not so much for financial gain but to create chaos, disrupt operations, or for long-term effects on an organization. By deleting such critical data, an attacker cripples the organizational operations at a high risk of costly downtime and business disruption. In contrast, wiper attacks primarily target the direct destruction of valuable information whereas ransomware mainly relies on extorting money. Thus, it is even more hazardous in environments where data integrity is of high value.

How Wiper Attacks Affect Business Continuity

Wiper attacks would have also been a contributor to severely affecting the continuity of businesses, by disrupting operations and causing a long period of downtime. The immediate consequences of such attacks often manifest in multiple ways:

• Operational Disruption: When critical data gets erased, organizations face the inability to access crucial information leading to halted productivity. This can cause not only the tasks at hand to get disrupted but also other business functionalities, causing delays on projects and affecting the entire workflow. The departments of shared data will be affected because the delay in one portion creates ripples across the entire organization. Marketing teams may not be able to launch their campaigns while finance departments could struggle in processing some of the transactions or even payroll.
• Financial Losses: Financial loss resulting from a wiper attack is enormous. The cost resulting from data recovery, system rebuilding, and enhanced IT support become burdensome. In addition, the lost time that an organization experiences due to a wiper attack is equivalent to revenues and productivity not obtained, further increasing the strain on its financial resources. The companies also incur unnecessary costs since it has to engage external cybersecurity analysts to analyze the breach and restore systems back to functionality. In extreme cases, the cost of a wiper attack can be in the millions, especially for large organizations where a minute lost can translate to hundreds of thousands of dollars.
• Damage to Customer Trust: In the cutthroat market today, customer trust is invaluable. Data loss due to a wiper attack may raise a question and doubt within the minds of clients as to the dependability of the organization and its security measures. The outcome of such damage with respect to customer goodwill would be reduced customer loyalty, bad word-of-mouth, and even loss of potential future business. For example, customers may take their businesses elsewhere if they fear that their data might not be secure, hence a long-term loss in revenues. In addition, the public relations efforts that can also strive to undo these impacts take significant resources and time in the process.
• Regulatory Penalties: Companies operating in regulated industries are exposed to legal and regulatory challenges when a data wiper malware destroys information. Violation of confidentiality would attract the regulatory authorities through fines, court actions, and other compliance-related expenses that are total to the bottom-line impact of the attack. The regulatory bodies might also raise the standards. This would result in immense investment in security solutions. Focus and efforts would be diverted toward such attention away from the core business activities.
• Long-term Viability: The inability to recover from a wiper attack can pose threats to the long-term viability of an organization. Even if critical information cannot be recovered, since it is lost, strategic decision-making may be compromised and, hence, growth potential and overall operational effectiveness may be curtailed. Organizations may fail to honor contracts with their clients or deliver services and therefore threaten their reputation in the industry. At times, attacks from highly virulent wipers can be so extreme that companies can shut them down entirely, and, therefore, exemplify the life-or-death threat that this kind of malware poses.

Types of Wiper Malware

Wiper malware has been programmed to execute data destruction in various ways, designed to suit different targets and objectives. Among the most common ones are as follows:

• File Wipers: They are aimed at deleting specific files or folders in the system. Targeting specific documents creates pandemonium without necessarily uprooting the whole system. This enables the attackers to strategically target critical files to operations that may include project documents or sensitive reports. This may hinder the ability of an organization to function and may take a significant amount of time and effort to rebuild lost data.
• Disk Wipers: Disk wipers will erase the entire disk drive or partitions, completely erasing all the data on them. In the damage that results, a significant amount of information will not be recoverable. To the injured organization, its critical software applications and databases will be useless, and it will have to engage in a huge effort to reinstall software and recover information from backups, if any existed in the first place, causing enormous downtime and operational challenges.
• MBR Wipers: These wipers target the master boot record, which is part of a storage device that contains information regarding how the operating system is to be loaded. Once the MBR gets corrupted, it is impossible for the operating system to boot thereby rendering the machine useless. It may be necessary to restore the entire installation of the OS, implying a significant loss in terms of time and resources. The impact of system failure can be quite magnified if multiple machines have been affected, thereby making recovery efforts more complicated.
• Database Wipers: This malware is designed to damage or destroy entries in a database. It causes critical disturbances, mainly in organizations that depend on data management. The complete disruption and major setbacks in data-driven decision-making occur from the loss of information in databases. The operational information of businesses, if they rely on real-time data for decisions, can be seriously crippled in the ability to make wise choices which may result in costly errors and missed opportunities.

In addition to these specific types of wiper malware, organizations must also be aware of threats like scareware, which can compound the chaos by tricking users into believing their systems are infected, leading to unnecessary actions that may further compromise security.

How Wiper Malware Works

Wiper malware follows a multi-stage attack process that is, primarily, aimed at inflicting maximum damage by wiping out critical data and crippling entire systems. Knowing this mechanism can help in better defending an organization from it or other malicious threats.

1. Initial Infection: Wiper malware enters a system using a plethora of attack vectors. So commonly encountered are phishing emails with embedded links or attachments the user has been tricked into downloading without knowing what they do. Other forms of attack are to transfer the malware across from removable media, in the form of USB keys, for example. Once installed, the malware can begin its silent infiltration.
2. Command Execution: Following the installation of the malware to the system, it will initiate a series of delete or overwrite commands on sensitive data. Here, it systematically deletes files, folders, or even entire drives. In some of the advanced cases, it might manipulate data structures or metadata in the filesystem to make the data unrecoverable. The effect of such strategic execution is the elimination of such large amounts of data and its irrecoverability.
3. Evasion Techniques: Evading malware often uses advanced techniques of evasion. For instance, it may deactivate antivirus software, alter system logs to remove signs of its existence, or mask its processes as authentic system events. Hence, by mimicking normal behaviors, it evades detection until much too late in the situation. This is why organizations must continually monitor and be proactive concerning cybersecurity measures.
4. Data Loss: The summation of the successful wiper attack is catastrophic data loss. Once the malware executes its deletion commands, files and systems can become permanently unrecoverable. It is not only a temporary short-term disruptive operation but also has long-term effects because organizations will be unable to recover key information necessary for daily functions. Impacts can trickle down to create unhindered productivity, financial instability, and even losing customers.

How to Detect and Prevent Wiper Attacks

Since wiper attacks tend to be stealthy by nature, detection, and prevention can prove rather difficult. However, organizations can leverage a strong multi-layered approach in order to solidify their defenses:

1. Regular Backups: The best way of limiting the impact of a wiper attack would be to maintain regular and secure backups. This would ensure that all such important data are backed up frequently to safe offsite locations; consequently, permanent data loss would become less probable. Regular testing of backup integrity and accessibility can also ensure an operation within a short time after an attack.
2. Intrusion Detection Systems (IDS): A robust IDS has to be used to track network traffic and identify strange activities that might be that of an attack by a wiper. IDS can identify patterns or anomalies that alert an intrusion so that security teams come to inspect potential threats before they become huge issues. Highly advanced IDS based on machine learning can be invested in to increase its capability of detection.
3. Security Awareness Training: Educating employees about potential threats is a critical component of any cybersecurity strategy. Training programs should cover various topics, including identifying phishing attempts, understanding the dangers of unsolicited downloads, and promoting safe browsing habits. An informed workforce acts as a critical line of defense, helping to prevent initial infection points for wiper malware.
4. Regular Security Audits: Regular comprehensive security audits of the systems will help identify and mitigate vulnerabilities that might exist in any system. This will be an analysis of both technical controls and organizational policies to ensure that security measures are current and effective against emerging threats. Identifying weaknesses proactively reduces the risk of experiencing wiper attacks or other cyber threats.
5. Endpoint Protection: It focuses on the implementation of advanced endpoint protection solutions when it comes to malicious activities, such as identification and blocking before compromising the system. Solutions that include behavior-based detection and machine learning algorithms effectively monitor for endpoints with signs of the wiper malware, therefore providing additional security.

Best Practices for Recovering from a Wiper Attack

The recovery process from a wiper attack is complex and challenging; however, adhering to the best practices of restoration can help an organization regain operations quickly with minimal damage. Some of the key strategies for recovery are as follows:

1. Immediate Isolation: Once the presence of a wiper attack is established, isolate affected systems immediately from the network. It will prevent the malware from spreading further and minimize data loss if the access of the infected devices from other systems is removed. This may include taking the systems offline or disabling their network connections to make sure that the spread is not possible.
2. Data Recovery: Data recovery should begin once affected systems have been isolated. This typically occurs by leveraging accessible current backups to recover lost data. Anyone who regularly takes scheduled backups that are stored securely and tested for integrity may find those to be extremely helpful at this recovery stage. If no backups exist or those too are impacted, companies may have little option but to look for data recovery services, with no guarantee of success.
3. Forensic Analysis: A thorough forensic analysis would give the organizations involved knowledge of the nature of the attack. It would involve studying the entry process of the wiper malware, the weaknesses it exploited, and what was lost. Such information would aid immunity against such attacks in the future. Moreover, the process would be incident documentation to fulfill all the requirements on the aspects of compliance and reporting.
4. Communication: Keeping the stakeholders, customers, and employees well-informed on the issue of the wiper attack is very important. Taking them into confidence maintains transparency and trust. Letting the stakeholders know the status of the recovery activities and their potential effects on customers or services would be very helpful. Proactive communication is hence positive as it negates reputational damage or any other losses, using credible communication to exhibit stakeholder concern that the organization takes the incident seriously.
5. Review and Revise Incident Response Plans: In organizations, the process of recovery serves as an avenue to review their incident response plans and processes. This review will discern the things that have worked well in responding to the incident and also determine the areas that are calling for change. By this, the organization will be better situated to counter any future threat after integrating the lessons learned into the incident response strategy.
6. Enhance Security Measures: As a matter of fact, the recovery process should enforce improved security. This is where advanced threat controls to keep a vigilant eye on those threats, multi-factored authentication, and developing different training programs for employees can help. This would thereby save the organizations from future wiper attacks and other malicious cyberattacks.

Understanding the Role of MBR Wipers in Cyber Attacks

MBR wipers pose particularly perilous types of wiper malware since they target so specifically. When a system’s Master Boot Record—the vital part of its storage system—is wiped, the attack can leave a computer incapable of functioning. Here’s what organizations should know about MBR wipers:

1. Targeting Critical Components: The Master Boot Record is essential for booting an operating system, as it contains information about the disk’s partitions and the operating system loader. When MBR wipers attack this critical area, they can block the system from booting up and literally shut off the system. This is a significant operational disruption and data unavailability.
2. Impact on Recovery: Recovery from a Wiper MBR attack is particularly deleterious. Because the MBR is involved in the boot process, often specific recovery tools or services are needed, capable of repairing or rewriting the compromised MBR. Sometimes this involves the full restoration of the operating system, which again complicates the recovery activities themselves.
3. Preventive Measures: Organizations have to take appropriate protective measures to avoid MBR wiper attacks. Scheduled backups that include system images can prove to be of great help in points of recovery in case of an MBR wiper attack. Updating the operating system and applications along with the usage of powerful endpoint protection solutions would also help in decreasing the possibility of such attacks. The IDS installation along with the monitoring of network traffic happening in the network may also raise an alarm for possible instances of attacks.
4. Awareness and Training: Educating IT staff and employees on MBR wipers awareness can keep a strong defense in an organization. Overall, training IT staff and employees on phishing attempts and malicious attachments can become the most common entry points for wiper malware to prevent initial infections.

Mitigate Wiper Attacks with SentinelOne

SentinelOne uses advanced behavioral AI and can identify Wiper attacks in real time. For instance, it can identify patterns that indicate abnormal file access as one of the signs of the presence of a wiper, and it acts instantly before damage is extensive. Once a wiper attack is detected, SentinelOne has containment features that isolate systems affected by the malware thereby preventing the spread of bad code and further compromising a network.

Remediation capabilities offered by SentinelOne will help organizations roll back affected systems to the pre-attack state so that business can be conducted without much delay and with reduced downtime. Real-life scenarios that occurred during cyber attacks on Ukraine’s infrastructure had organisations protected with SentinelOne limiting the damage significantly and restoring their services faster than those organisations without such protections.

To ensure that such incidents do not happen again, SentinelOne uses threat intelligence and continuous monitoring, giving enterprises a chance to identify vulnerabilities before they can be exploited. With this proactive security posture, organizations are put ahead of wiper threats in evolution. Organizations would then protect their critical assets from being targeted in the first place, and that’s what SentinelOne provides by combining AI threat detection, containment, remediation, and evolving threat intelligence.
