Cybercriminals disguise their malicious software as legitimate applications to trick users into downloading it. One such example is the “infostealer’ malware disguised as an Adobe Reader installer.

What is an Infostealer?

An infostealer is a type of malware that steals sensitive data from a victim’s system. This stolen data could be:

• Usernames, passwords, for online accounts (banking, email, social media, etc.)
• Credit card numbers, bank account details
• Names, addresses, phone numbers, Social Security numbers (if applicable)
• Websites visited, online searches performed

Upon data collection, the infostealer sends it back to the cybercriminal via web. Cybercriminals leverage these stolen data to commit Identity theft, Financial fraud, Selling your information on the dark web & launching further attacks.

How does the Adobe Reader Infostealer Work?

Deceptive Download

Cybercriminals create a fake website or pop-up ad that mimics the official Adobe Reader download page. Users visiting these sites may download as they believe it is a legitimate Adobe Reader installer.

Malware Installation

Instead of installing Adobe Reader, the downloaded file installs the infostealer malware onto the victim’s computer. The installation process could include the legitimate Adobe Reader software to avoid suspicion.

Data Harvesting

Once installed, the infostealer runs in the background. It collects sensitive data such as login credentials, credit card numbers & browsing history.

Data Transmission

The stolen data is then sent back to the cybercriminal, who can use it for criminal activities.

How to Protect Yourself from Infostealer?

Download from Official Sources

It is recommended to download only from official website or a trusted source. Avoid clicking on pop-up ads or suspicious links that claim to offer software downloads.

Verify the URL

Check the URL of the website to ensure it is legitimate. Look for the “https://” prefix and a padlock icon in the address bar.

Use Security Software

Install &regularly update reputable antivirus, anti-malware software to detect and prevent malicious downloads.

Be Cautious with Emails

Be wary of unsolicited emails that prompt you to download software or click on links. Verify the sender’s identity before taking any action.

Keep Software Updated

Regularly update all software, including your OS & applications, to protect against known vulnerabilities.

Wrap Up

Infostealers are a serious threat because they can be very difficult to detect. They often run in the background without any noticeable symptoms. They could also be disguised as legitimate software.
