Malware in Cars and Hacking Cars

-
If a hacker were to bring in a malware-harboring car for service, the vehicle could spread that infection to a dealership’s testing equipment, which in turn would spread the malware to every vehicle the dealership services, kicking off an epidemic of nasty code capable of attacking critical driving systems like transmission and brakes.
Once you compromise a dealership, you’d have a lot of control,” “You could create a malicious car…The worst case would be a virus-like system where a car pulls in, infects the dealership, and the dealership then spreads that infection to all the other cars.”
That “auto brothel” attack is hypothetical, but it’s not as farfetched as it might seem. In 2010 and 2011, researchers at the University of California at San Diego and the University of Washington revealed a slew of hackable vulnerabilities in a 2009 Chevy Impala that allowed them to perform tricks like disabling its brakes, although they didn’t name the make or model of the vehicle at the time. One of those attacks was designed to take advantage of an auto dealership: The researchers found that they could break into the dealership’s Wi-Fi network and gain access to the same diagnostic tools. Wi-Fi connections. From there, they could hack any vehicle an infected tool plugged into.
Stefan Savage had said
“Any car ever connected to it, it would compromise,” the computer science professor who led the UCSD team in 2011. “You just get through the Wi-Fi in the dealership’s waiting room and the attack spreads to the mechanics shop.”

Consumer Dispute resolution under the Telecom Act 2023

-

The Telecommunications Act of 2023 has strengthened the dispute resolution framework by introducing an online grievance redressal system. The aim is to expedite the resolution of conflicts between telecommunications companies and consumers while ensuring transparency in the redressal process. Following an inquiry, a telecom company found violating license or service terms may incur severe penalties, spectrum holdings cancellation, service restrictions, or even be prohibited from providing telecom services, depending on the seriousness of the breach.  How does the online grievance redressal system operate, and who plays key roles?   An Adjudicating Officer (AO), appointed by the Centre and not below the rank of joint secretary, will conduct inquiries to resolve disputes between telecom service providers and consumers. Additionally, a separate Designated Appeals Committee (DAC) will be formed, consisting of officers at the rank of additional secretaries. Individuals dissatisfie...

Types of Cyber Attacks

Types of Cyber Attacks There are several effective methods for disrupting computer systems. We are talking of a method known as cyber attack, or computer network attack , which uses malicious computer code to disrupt computer processing, or steal data.  A brief description of three different methods are shown here. However, as technology changes, future distinctions between these methods may begin to blur. An attack against computers may be targeted or un-targeted (i) disrupt equipment and hardware reliability, (ii) change processing logic, or (iii) steal or corrupt data. The methods discussed here are chosen based on the technology asset against which each attack mode is directed, and the effects each method can produce. The assets affected or effects produced can sometimes overlap for different attack methods.  Conventional kinetic weapons can be directed against computer equipment, a computer facility, or transmission lines to create a physical attack that ...

What to do when police does not take your FIR?

What to do when FIR is not taken by the Police ? A First Information Report is the first legal document that initiates criminal proceedings. The first information received about the commission of a cognizable offense has to be noted down by a Police Officer. It is called as  First Information Report under Section 154 of CRPC. Cognizable and Non-Cognizable Offences: Cognizable offences  are offences where the police can arrest the accused without any warrant. In such offences, the police can Suo-moto take cognizance of the offence and it does not require any sanction from the court in order to begin the investigation. On the other hand,  Non-Cognizable  offences are those in which police cannot make an arrest without taking prior assent from the court. Schedule I of the Criminal Procedure Code clearly distinguishes which offenses are cognizable and which are not. According to section 154(1) of the Criminal Procedural Code,  an FIR can be filed only in cognizable ...
