Hugo addresses common concerns about online security and privacy that viewers have while spending significant time on the internet.

Félix, a cybersecurity specialist working at Kaspersky with expertise in online security, is introduced to answer collected viewer questions.

Hugo collected questions from Instagram followers and other YouTubers in the Kaspersky brigade to address the most common security concerns.

To clarify and explain online security risks in approximately ten minutes through expert answers.

• Theft of banking data and financial information • Ransomware attacks involving encryption of personal files and data

Hackers encrypt important documents like theses and backups, then demand payment for decryption of the data.

Hackers steal photos from computers and threaten to publish them unless the victim pays money.

Victims lose access to critical files and face financial and reputational damage through these extortion tactics.

• Interception of data by someone on the same network • Fake public WiFi networks set up by pirates in airports and train stations

Hackers create fraudulent WiFi networks and request connection credentials or banking information from users trying to connect.

Using a VPN is the primary solution to protect data on public WiFi networks.

Using mobile 4G or 5G networks instead of public WiFi reduces exposure to these risks.

Private browsing only prevents people sharing the same computer from seeing which websites you visit.

• Internet service providers can still see which sites you visit • Websites you access can track your visits • In corporate networks, employers can monitor browsing activity

True anonymity on the internet is virtually non-existent despite using private browsing mode.

Private browsing ensures that people sharing your device remain unaware of your browsing habits.

• Store login credentials and maintain session connections to services • Remember user preferences and display settings on websites

Cookies themselves do not present direct security risks beyond tracking activities.

The main risk with cookies is tracking for targeted advertising purposes to personalize ads based on user behavior.

Companies use cookie data to understand user interests and display relevant advertisements.

• Use a phrase as a password instead of single words • Include accents, spaces, uppercase letters, numbers, and special characters like ? or !

Traditional passwords are becoming obsolete and are being replaced by two-factor authentication methods.

• SMS authentication • Certificate-based authentication • Other multi-factor verification methods reduce hacking chances significantly

Saving passwords in browsers is risky because anyone accessing your computer could steal the password database.

Social networks primarily use collected data to finance operations through targeted advertising and user profiling.

• All user interactions with the platform • Click activities and engagement metrics • Location information and precise geographic positioning • User interests inferred from behavior patterns

Social networks track user interests at specific times to display personalized advertisements related to recent browsing or clicks.

The primary risk occurs if social networks experience a security vulnerability allowing third parties to steal and misuse the collected data, as seen in the Cambridge Analytica case.

Hackers can technically access webcams and microphones by installing applications on computers, smartphones, or devices without proper validation.

Hackers prioritize quick financial returns and generally do not waste time watching random webcams waiting for opportune moments to gather compromising content.

• Fake dating profiles where scammers pose as real people and request inappropriate photos • Photos sent to partners that can be shared or leaked to others • Malicious applications disguised as legitimate apps that secretly access cameras at any time

Using camera covers or tape on devices serves as a precautionary measure to prevent unauthorized access.

The human factor is very important and users must remain constantly alert to security threats.

Keeping products and applications updated is crucial as updates often resolve security vulnerabilities and problems.

Installing and maintaining antivirus software provides essential protection against cyber threats.
