What is StrandHogg that affects Android OS?

The Union Ministry of Home Affairs (MHA) has sent an alert to all States warning them about the vulnerability of Android operating system to a bug called ‘StrandHogg’, which allows real-time malware applications to pose as genuine applications and are able to access user data of all kind. The information was shared by Threat Analytical Unit, Indian Cyber Crime Coordination Centre (ICCCC) so as to take steps to create awareness among public on vulnerability of Android to ‘StrandHogg’.

About StrandHog

While all versions of Android (including Android 10) are vulnerable to this bug, but it may not be apparent to affected users that malware applications are already on board their device.

How does it affect? This malware can then potentially listen to users conversations, make calls, record conversations, access photo album, read or send messages, as well as get login credentials to various accounts. Such malware can also access private images, files, contact details, call logs, and location information.

Warning signs? Pop-up notifications in phone, asking for permission to send notifications, messages etc., are one of the main entry points for ‘StrandHogg’ to launch the attack. An app in which user is already logged in asking him/her to login again is another anomaly pointing to possibilities of a cyberattack. Once such requests are approved by users, the malware would instantly access mobile phone/ tablet for specific purposes. It can then activate microphone, allowing a hacker in a remote location to listen to live conversations and even camera could be switched on to capture visuals.

Trakea: A Unique bar-coding software used by Haryana Police

The Haryana Police Department has adopted a unique barcoding software. The software is used to ensure that 1000s of digital forensic reports are stored safe and secure. It offers a foolproof security to the samples collected from the crime scene.

Conventional Forensic Management

In conventional methods, the crime exhibits like parcels or samples are labeled with details like FIR number, names and addresses of victim, medical officers and accused. The crime exhibits include documents, DNA samples, serology, toxicology or biology examinations, lie detections, etc. These exhibits are easy to track and trace as they are stored on FIR number and are available to be tracked virtually by anyone.

About the Software

The Software features two stages of bar coding to maintain the secrecy of the samples. The samples and reports are sent through biometrically authorized chain. The cases are allocated to the biotechnology experts through automated case allocation. Therefore, the experts will not know about the details of the case or the names associated with case. Similarly, the police department or the other officials associated with the case will not know about the details of the professional performing the examination.


The software is android based and has been prepared in an application format. Therefore, usage becomes simple. It can be well integrated with the judicial system and doing so will help reduce time lags. Above all, the system helps in reducing malpractices greatly.
