How to Hack EVM Machine? Understanding Their Security and Resistance to Hacking.

Electronic Voting Machines (EVMs) have revolutionized the electoral process in many democracies by providing a fast, efficient, and reliable method of casting and counting votes. Despite their widespread adoption, concerns about their security and potential vulnerability to hacking persist. This article delves into the security mechanisms of EVMs, examines the challenges and misconceptions surrounding their potential for tampering, and highlights the measures in place to ensure the integrity of elections.

Understanding EVM Security

EVMs are designed to be robust and tamper-proof, incorporating multiple layers of security to prevent unauthorized access and manipulation. These machines have been used in several countries, including India, Brazil, and the United States, and have undergone rigorous testing and validation by independent experts and government agencies.

Physical Security Measures

  1. Sealed Units: EVMs are sealed with tamper-evident seals before and after the election process. These seals make it evident if any unauthorized access has occurred.
  2. Controlled Access: Only authorized personnel, such as election officials, can access and operate the EVMs. The machines are stored in secure locations under strict surveillance when not in use.
  3. Standalone Devices: EVMs are standalone devices that are not connected to the internet or any external network, making remote hacking virtually impossible.

Technical Security Features

  1. Unique Firmware: Each EVM operates on a unique firmware that is not publicly accessible, reducing the risk of software tampering. The firmware is rigorously tested and certified before deployment​ (​.
  2. Voter Verifiable Paper Audit Trail (VVPAT): VVPAT systems provide a physical printout of each vote cast, allowing voters to verify their selection. These paper trails can be cross-verified with electronic results to ensure accuracy and transparency​ (PWOnlyIAS)​.
  3. Regular Audits and Testing: EVMs undergo regular audits and pre-election testing to ensure they are functioning correctly. Mock polls are conducted to verify their accuracy and reliability before actual voting begins​ (Hindustan Times)​.

Common Misconceptions and Challenges

Despite the stringent security measures, EVMs have been at the center of various controversies and misconceptions.

The Myth of Remote Hacking

One of the most persistent myths is that EVMs can be hacked remotely. Given that EVMs are not connected to the internet or any external network, remote hacking is not feasible. All data is stored locally within the device, which must be physically accessed to alter any information​ (​​ (PWOnlyIAS)​.

Claims of Tampering

Over the years, there have been several claims of EVM tampering. However, these claims often lack substantial evidence. For instance, the Election Commission of India (ECI) has repeatedly demonstrated the security of EVMs through public challenges where experts and political parties were invited to tamper with the machines. These challenges have consistently shown that EVMs are secure and tamper-proof​ (Hindustan Times)​.

Measures to Enhance Trust and Transparency

To further enhance trust in the electoral process, various measures have been implemented:

  1. Public Demonstrations and Challenges: Election commissions in different countries regularly conduct public demonstrations and hacking challenges to showcase the robustness of EVMs and address any security concerns.
  2. Independent Audits: Independent technical experts are often invited to audit the EVMs and their software to ensure they meet the highest security standards​ (​.
  3. VVPAT Implementation: The integration of VVPAT with EVMs provides an additional layer of verification, allowing for manual recounts and audits if necessary​ (PWOnlyIAS)​.


EVMs represent a significant advancement in electoral technology, offering a secure, efficient, and reliable method of voting. While no system is entirely foolproof, the extensive security measures and continuous improvements in EVM technology ensure that elections are conducted with the highest integrity. The myths surrounding EVM hacking largely stem from misinformation and a lack of understanding of the robust security protocols in place. By maintaining transparency and inviting independent audits, election commissions worldwide can continue to uphold the trust and confidence of the electorate.
