What is Personally Identifiable Information (PII)?

Personally identifiable information (PII)

In a disturbing revelation, Resecurity, an American cybersecurity company, has uncovered a massive data breach compromising the personally identifiable information (PII) of 815 million Indian citizens. The breach includes highly sensitive details such as Aadhaar numbers and passport information, all of which are being sold on the dark web by a threat actor known as “pwn0001.” This alarming breach has raised significant concerns about data security, identity theft, and the government’s response in India.

Understanding Personally Identifiable Information (PII)

Definition of PII: Personally Identifiable Information (PII) encompasses data that can identify an individual, including both direct identifiers like passport information and quasi-identifiers that, when combined, can reveal a person’s identity.

Details of Compromised Information: The compromised data involves Aadhaar numbers, unique 12-digit individual identification numbers issued by the Unique Identification Authority of India (UIDAI) on behalf of the Indian government. This data is currently being offered for sale by the threat actor “pwn0001.”

Additional Compromised Information: Adding to the gravity of the situation, another threat actor named “Lucius” claims to possess access to a more extensive array of PII data, including voter IDs and driving license records, raising concerns about the scale of the breach.

Access to Sensitive Data by Threat Actors

Unclear Origins of Data Breach: A significant challenge in addressing this breach is the lack of specific information from the threat actors regarding how they obtained this data, making it challenging to pinpoint the source of the breach.

Claims of Data Access: “Lucius” alleges access to a 1.8 terabyte data leak, impacting an unnamed “India internal law enforcement agency.” However, the authenticity of this claim is yet to be verified, further complicating the investigation.

Security Measures and Government Response

Investigation by India’s CERT-In: India’s Computer Emergency Response Team (CERT-In) is actively investigating the reported data leak. However, the government has not yet confirmed the size of the breach, leaving many questions unanswered.

Challenges in Data Security: India’s junior IT minister, Rajeev Chandrasekhar, acknowledged the challenges in transitioning to a robust data security infrastructure, citing previous instances of data leaks, including those related to Aadhaar and the PM Kisan website.

Threats Arising from the Leaked Information

Increased Cyberattacks: India has witnessed a significant surge in disruptive cyberattacks, leading to heightened risks of digital identity theft and cyber-enabled financial crimes.

Vulnerability to Identity Theft: With India ranking fourth globally in malware detection, the leaked information poses a serious threat, enabling threat actors to carry out various malicious activities, including online-banking theft and tax frauds.

Impact of Unrest in West Asia: Recent disturbances in West Asia have exposed personally identifiable data, exacerbating the risk of identity theft and other cyber threats, as this data can be used in various malicious activities.

Safeguarding Personal Information: User Measures

Check for Personal Data Leaks: Users are advised to determine whether their information has been compromised in the data breach, as being informed is the first step in protecting oneself.

Exercise Caution with Emails and Accounts: Vigilance is crucial, especially when dealing with emails from unknown sources, as stolen information may be used for phishing campaigns and brute force attacks.

Implement Two-Factor Authentication: To enhance security, users should enable two-factor authentication for all their online accounts and promptly report any suspicious activity to the authorities.

Be Mindful of Security Upgrades: Regularly updating security measures and staying informed about emerging threats is essential for safeguarding personal information in an increasingly digitized world.

As the investigation unfolds and the government takes measures to address this breach, it is imperative for individuals to take personal responsibility for their data security. The gravity of this situation emphasizes the urgent need for enhanced data protection measures, both at the individual and governmental levels.
