All citizens are using tech to their advantage, and so we see a lot of upskilling among the population leading to innovation in India. As we go deeper into cyberspace, we must maintain our cyber security efficiently and effectively. When bad actors use technology to their advantage, we often see data loss or financial loss of the victim, In this blog, we will shine light upon two new forms of cyber attacks, causing havoc upon the innocent. The “Daam” Malware and a new malicious app are the two new issues.
Since 2021, the DAAM Android botnet has been used to acquire unauthorised access to targeted devices. Cybercriminals use it to carry out different destructive actions. Using the DAAM Android botnet’s APK binding service, threat actors can combine malicious code with a legitimate application. Keylogging, ransomware, VOIP call records, runtime code execution, browser history collecting, incoming call recording, PII data theft, phishing URL opening, photo capture, clipboard data theft, WiFi and data status switching, and browser history gathering are just a few of the functions offered by the DAAM Android botnet. The DAAM botnet tracks user activity using the Accessibility Service and stores keystrokes it has recorded together with the name of the programme package in a database. It also contains a ransomware module that encrypts and decrypts data on the infected device using the AES method.
Additionally, the botnet uses the Accessibility service to monitor the VOIP call-making features of social media apps like WhatsApp, Skype, Telegram, and others. When a user engages with these elements, the virus begins audio recording.
CERT-IN, the central nodal institution that reacts to computer security-related issues, claims that Daam connects with various Android APK files to access a phone. The files on the phone are encrypted using the AES encryption technique, and it is distributed through third-party websites.
It is claimed that the malware can damage call recordings and contacts, gain access to the camera, change passwords, take screenshots, steal SMS, download/upload files, and perform a variety of other things.
Safeguards and Guidelines by Cert-In
Cert-In has released the guideline for combating malware. These were issued in the public interest. The recommendations by Cert-In are as follows-
- Only download from official app stores to limit the risk of potentially harmful apps.
- Before downloading an app, always read the details and user reviews; likewise, always give permissions that are related to the program’s purpose.
- Install Android updates solely from Android device vendors as they become available.
- Avoid visiting untrustworthy websites or clicking on untrustworthy
- Install and keep anti-virus and anti-spyware software up to date.
- Be cautious if you see mobile numbers that appear to be something other than genuine/regular mobile numbers.
- Conduct sufficient investigation Before clicking on a link supplied in a communication.
- Only click on URLs that clearly display the website domain; avoid abbreviated URLs, particularly those employing bit.ly and tinyurl.
- Use secure browsing technologies and filtering tools in antivirus, firewall, and filtering services.
- Before providing sensitive information, look for authentic encryption certificates by looking for the green lock in your browser’s URL information, look for authentic encryption certificates by looking for the green lock in your browser’s URL bar.
- Any ‘strange’ activity in a user’s bank account must be reported immediately to the appropriate bank.
New Malicious App
From the remote parts of Jharkhand, a new form of malicious application has been circulated among people on the pretext of a bank account closure. The bad actors have always used messaging platforms like Whatsapp and Telegram to circulate malicious links among unaware and uneducated people to dupe them of their hard-earned money.
They send an ordinary-looking message on Whatsapp or Telegram where they mention that the user has a bank account at ICICI bank and, due to irregularity with the credentials, their account is being deactivated. Further, they ask users to update their PAN card to reactivate their account by uploading the PAN card on an application. This app, in turn, is a malicious app that downloads all the user’s personal credentials and shares them with the bad actors via text message, allowing them to bypass banks’ two-factor authentication and drain the money from their accounts. The Jharkhand Police Cyber Cells have registered numerous FIRs pertaining to this type of cybercrime and are conducting full-scale investigations to apprehend the criminals.
Malware and phishing attacks have gained momentum in the previous years and have become a major contributor to the tally of cybercrimes in the country. DaaM malware is one of the examples brought into light due to the timely action by Cert-In, but still, a lot of such malware are deployed by bad actors, and we as netizens need to use our best practices to keep such criminals at bay. Phishing crimes are often substantiated by exploiting vulnerabilities and social engineering. Thus working towards a rise in awareness is the need of the hour to safeguard the population by and large.
