Felt amazing while working with children on their after school time, the children wanted to learn so was easy to carrying on with and showing them things that they are seeing for the first time was a great and reward for my time with them.

Here, all the best practices, experience, tweaks, troubleshooting, WAN accelerators have huge importance.
I am very proud to had been involved in this 5 years project or more, I was in full time working in the initial 3 years.

🛡️ Critical Vulnerability Found on justice.gov.uk Me and my brother Kazi Sabbir recently discovered a high-impact vulnerability on a UK Government subdomain — justice.gov.uk — which we have now responsibly reported. The issue originated from a forgotten and unrestricted API endpoint, which allowed us to inject and publicly render custom HTML, CSS, and JavaScript directly under the trusted *.justice.gov.uk domain. With this flaw, an attacker could have: ▫️Crafted realistic phishing pages, impersonating government services. ▫️Hosted fake login portals to steal credentials or personal information. ▫️Delivered malicious scripts to perform client-side attacks. ▫️Leveraged the domain’s trust to bypass spam filters and deceive users via email. ▫️Spread false information, mimicking official government statements. ▫️Created fraudulent payment pages, tricking victims into sharing sensitive financial data. This issue posed a serious risk to public trust and the security of government services. We found the issue through a forgotten, misconfigured API endpoint and reported it through responsible disclosure — helping protect a trusted government platform. #BugBounty #CyberSecurity #ResponsibleDisclosure #EthicalHacking #UKGov #JusticeGovUK #InfoSec #WebSecurity

Cyber-spying is possible with embedded sensors in the mobile phone. For those who don't know, modern mobile devices are full of these sensors and they all look innocent. Because of their embedded mechanisms, most data is hosted locally. The most widely used of these sensors are MEMS (Micro-Electro-Mechanical Systems) based structures such as accelerometers, gyroscopes and magnetometers. As a note and an example, these sensors are usually called directly at the system level via APIs such as SensorManager (Android) or Core Motion (iOS). Third-party applications can receive hundreds of samples per second through these APIs, subject to permissions. Sensor data is usually unencrypted, processed directly in user space, and accessible to multiple applications simultaneously. If you are curious, you can check how many apps installed on your mobile device ask for this permission. With each permission, the manufacturer can access your sensor data. Keylogger? Yes, even that is possible. When typing on a mobile device, the user creates very slight tilts and movements on the surface of the device. In 2014, a concept called Touchlogger demonstrated that by analyzing only gyroscope and accelerometer data, it could predict with up to 70% accuracy which keys the user pressed on a virtual keyboard. Ambient sound listening? That is possible. Gyroscopes show a low frequency (typically 80-250 Hz) sensitivity to sound waves. This makes them low-resolution passive microphones. In 2014, researchers from Stanford University developed a system that uses gyroscope sensors in mobile devices to detect surrounding speech. Take a look at the concept of a "gyrophone". PIN attack? Yes. Mobile browsers support access to sensor data via JavaScript. This means that sensor data can be collected from a user simply by visiting a website, without the need to install an application. A 2017 study by Newcastle University showed that by collecting accelerometer and gyroscope data through a web page, 4-digit PINs can be guessed with 74% accuracy. To all this you need to add behavior patterns. If I tell you that the Pegasus spyware developed by NSO Group also accesses sensor data, I think you will understand the seriousness of the situation. Such data has been used to determine when the target person is in a meeting, how often they enter and leave a room, or even if they are asleep. The misuse of these sensors threatens not only individual privacy but also national security. In particular, surveillance of vulnerable individuals such as diplomatic officials, journalists and corporate executives through sensors on their devices poses a great risk. I suggest you take a look at this little spy data. Just as a matter of awareness, friends! ^-^/ #cybersecurity #dataprivacy #informationsecurity #privacy #technology #threatintelligence
