Quantum Computing and Cyber Threats from it !!

 What is Quantum Computing?

Quantum computing is a rapidly-emerging technology that harnesses the laws of quantum mechanics to solve problems too complex for classical computers.

Why do we need Quantum Computers?
Quantum computers will help immensely with problems related to optimization, which play key roles in everything from defence to financial trading.

The Cybersecurity Implications of Quantum Computing

·       Threat 1: Harvest Now, Decrypt Later-
Threat actors collect encrypted data from target organizations today, fully anticipating that data can be decrypted later when quantum computing reaches a maturity level capable of rendering many publicly utilized cryptographic algorithms like RSA entirely obsolete.

·       Threat 2: Making Asymmetric Cryptography Obsolete
It poses a “Quantum Threat,” a match for the complicated math problems previously unbeatable by classic computers. The world's data, currently protected by asymmetric cryptography algorithms such as RSA, DH and ECC, will soon become readable – and subsequently, easy for cybercriminals to infiltrate and bring down global digital security.

·       Threat 3: The vulnerabilities of blockchain technology-
Because blockchain depends on the disseminated consensus of trust, achieved through the use of public-key cryptography, it is particularly susceptible to attacks that reveal a user’s private key given, only the public key.

Emerging Cyber Crime !!

 In India, cyber crime has emerged a lot. From password hacking to national cyber crime, Cyber crime has evolved a lot. Nowadays money is been transferred by hackers to their account from people accounts unknowingly that this is a crime . This type of Hacking or Hijacking of money of people's bank accounts by hackers is a cyber crime which must be reported in the cyber cell. In India it can be reported on the contact number 1930. MY OWN EXAMPLE Speaking about the last week, my father received a call which said - ' we are speaking from khufiya(undercover) agency, is it your son, he is going to be kidnapped and it can be stopped if my father gave the ransom amount', here my father scolded them knowing that this is a fraud call. But he took notice and asked about me from my mother. After I got to know about this, knowing this is a scam call I reported this in cyber cell (1930). Cyber cell not only takes action on the report but also spread awareness about such incidents. Again...

BlackRock Scam Explained: How a Telecom Giant Fell for a Phishing & Investment Fraud

Who is BlackRock? BlackRock is a renowned global firm with major operations in New York and London. While it is often associated with finance, in this context we refer to BlackRock’s telecommunication partnerships and its global influence—similar to what Airtel holds in India. However, unlike Airtel, BlackRock recently became a victim of a massive investment and phishing scam. Phishing and Investment Scam: What Happened? According to reports, Indian-origin telecom executive Bankim Brahmbhatt has been linked to an alleged multi-million-dollar fraud involving BlackRock. Here’s how the scam is believed to have unfolded: Brahmbhatt reportedly approached BlackRock claiming he had substantial investments from companies that were mutually associated with the firm. By building trust and maintaining regular communication with BlackRock, he managed to secure a loan of nearly $500 million . To support the claim, spoofed emails were allegedly sent to BlackRock from addresses mimicking o...

The Dark Side of the Internet: Understanding Online Bullying and Abuse

Introduction Nowadays, even children have the technology that was once only accessible to industry giants and MNC's. The difference is of maturity. This technology was once used to be for a good because as it was in safe hands, but as of now, it is seen that the the tech, the internet or the social media has both pros and cons.  If used in a good way, this may take us to reach great heights, but if used wrongly it may lead to paths which are unethical.
