In the ever-evolving threat landscape, wiper malware stands out as a particularly destructive force. Unlike traditional malware that aims to steal data or disrupt operations for financial gain, wipers focus on one objective: complete and utter data obliteration. These digital janitors leave a path of scorched earth, rendering systems unusable and causing significant downtime and data loss.

What is a Wiper ?

A “wiper” is a type of malicious software (malware) specifically designed to delete, corrupt, or permanently remove data from the targeted computer or network. Unlike other forms of malware, such as ransomware, which seeks financial gain by encrypting data and demanding a ransom for its release, wiper malware’s primary intent is to destroy data and cause disruption.

Wiper attacks can be particularly devastating because they aim to erase critical data and system files, leaving affected systems inoperable and often without the possibility of data recovery. This type of malware can target individual computers or spread across networks, impacting entire organizations.

The motivations behind deploying wiper malware vary but often include political reasons, cyber warfare, sabotage, or as a means to cover the tracks of other cybercriminal activities by destroying evidence. Wiper attacks have been used in high-profile incidents involving geopolitical tensions, targeting critical infrastructure, businesses, and government agencies to send a message, create chaos, or disrupt operations.

Due to the destructive nature of wiper malware, it’s crucial for organizations to maintain regular backups of their data in secure locations, implement robust cybersecurity measures, and have a comprehensive incident response plan in place to mitigate the impact of potential attacks.

The Destructive Four:

1.BiBi-Windows Wiper: This wiper, discovered in 2022, specifically targets Windows devices. It leverages legitimate disk management tools to overwrite critical system files, rendering the machine inoperable.

Origins and Context

• BiBi-Windows Wiper emerged during the Israel-Hamas conflict, where physical warfare spilled over into cyberspace.
• Initially discovered as BiBi-Linux Wiper, it targeted Linux systems used by pro-Hamas hacktivists.
• The malware’s name is a nod to the Israeli Prime Minister’s nickname, “Bibi” (Benjamin Netanyahu).

Technical Details

• MD5 Hash: e26bba0304f14ef96beb60376791d32c
• SHA256 Hash: 40417e937cd244b2f928150cae6fa0eff5551fdb401ea072f6ecdda67a747e17
• File Name: bibi.exe
• File Size: 203 KB
• Compiler: Visual Studio (2019)
• Timestamp: Compiled on October 21, 2023, just 14 days after Hamas’ initial terror attack on Israel.

Behavior

• Upon execution, BiBi-Windows Wiper checks the victim’s system architecture.
• It recursively overwrites data in the C:\Users directory with junk data.
• Each destroyed file bears the extension “.BiBi.”

Significance

• BiBi-Windows Wiper signals an escalation in cyber attacks, expanding its reach to end-user machines and application servers.
• By targeting Windows systems (which account for 68% of global desktop users), the threat actors aim to maximize impact.

2.BiBi-Linux Wiper: Similar to its Windows counterpart, BiBi-Linux Wiper focuses on Linux systems. It employs various techniques, including deleting files, overwriting boot sectors, and manipulating system libraries, to achieve its destructive goals. 

Context

• Initially identified during the Israel-Hamas war, BiBi-Linux Wiper wreaked havoc on Linux systems.
• Its purpose: pure data destruction, devoid of ransom notes or command-and-control servers.

Distinctive Features

• Israeli Prime Minister’s nickname, “Bibi,” hardcoded in the malware.
• Chaos-inducing cyberweapon deployed amidst the backdrop of war.

3.ChiLLWIPE: This wiper emerged in 2017 and has since evolved into multiple variants. ChiLLWIPE primarily targets Windows devices but has also been adapted for Linux and macOS systems. It utilizes a combination of file deletion, disk wiping, and encryption to inflict maximum damage. The culprit behind ChiLLWIPE remains unknown.

Overview

• ChiLLWIPE is another wiper strain that surfaced in the wild.
• Its origins and specific targets remain shrouded in mystery.

Behavior

• ChiLLWIPE systematically wipes files and directories, leaving no trace.
• Its chilling efficiency mirrors its name.

4.COOLWIPE: This wiper strain, discovered in 2020, exhibits worrism complexity and sophistication. COOLWIPE employs multiple techniques, including exploiting legitimate software vulnerabilities, to erase data across various operating systems, including Windows, Linux, and macOS. The developers of COOLWIPE are yet to be identified.

The Enigma

• COOLWIPE is an enigmatic wiper with limited visibility.
• Its creators and motivations remain elusive.

Impact

• COOLWIPE’s silent destruction leaves victims bewildered and dataless.

The Impact of Wipers:

While data deletion is the primary goal of wipers, their impact goes far beyond mere information erasure. Here are some key areas to consider:

1. Financial Losses:

• Downtime: Wipers can render systems unusable, leading to lost productivity, operational disruptions, and revenue drops.
• Data Recovery: Recovering lost data can be expensive and time-consuming, especially if backups are unavailable or compromised.
• Reputational Damage: Data breaches and service outages caused by wipers can severely damage an organization’s reputation, leading to lost customers and business opportunities.

2. Infrastructure Disruption:

• Critical Infrastructure: Wipers targeting power grids, transportation systems, or hospitals can have crippling effects, endangering lives and causing widespread chaos.
• Essential Services: Attacks on communication networks, financial institutions, or government agencies can disrupt essential services, impacting millions.

3. National Security:

• State-Sponsored Attacks: Wipers are often used by nation-states in cyberwarfare, leading to political instability and international tensions.
• Espionage and Sabotage: Wipers can be used to steal sensitive information or sabotage critical infrastructure for strategic advantage.

4. Psychological Impact:

• Fear and Uncertainty: Widespread wiper attacks can sow fear and uncertainty within communities, potentially even causing panic and social unrest.
• Erosion of Trust: The lack of data security and potential loss of personal information can erode trust in organizations and institutions.

5. Long-Term Effects:

• Recovery Costs: The financial and operational costs of recovering from a wiper attack can be substantial and long-lasting.
• Investment Deterrence: The threat of wiper attacks can deter businesses and organizations from investing in new technologies and infrastructure projects.

Beyond Financials:

Remember, the impact of wipers extends far beyond financial losses. These attacks can have a ripple effect, impacting national security, public safety, and even individual lives. Understanding these broader consequences is crucial to appreciate the true severity of the wiper threat.
