Being aware of all the possible internet security threats you can be a victim of is a must if you want to stay safe while browsing the web and doing all your everyday online activities, such as using your social network accounts, performing web banking transactions and even checking your e-mail. 2017 was a year of technological progress and new developments in every single area, and this also included malicious activity.

If you want to enjoy a safe internet experience during 2018, then check out this list of security threats you need to be careful with.

Identity theft

One of the biggest and most dangerous threats is identity theft. Malicious individuals or groups are always looking to steal user accounts, banking information, e-mail addresses and passwords in order to perform or aid themselves in their illegal activities posing as someone else. Another reason identity theft is such a big deal is because it may grant hackers access to sensitive information they can use to target a business or bigger organization.

Social network attacks

Social networks have spread into every single aspect of our everyday life, and they have become a widely used platform for malware distribution and phishing attacks. During 2018, it is expected that hackers and phishers exploit social networks to reach more people with their attacks and threats. Be careful with every link and post you see or receive on these social platforms, even if they come from people you know.

Mobile malware

Mobile devices such as phones and tablets have taken the lead over more traditional, desktop computers and others. As more and more people acquire one or more of these devices, cyber criminals are trying to develop more sophisticated and complex malware applications specifically targeted at them, serving as a bridge for information theft and other malicious activities. Mobile operating system developers must enforce more and better security measures to reduce the number of successful attacks on these platforms.

Data Breaches

Digital systems are always vulnerable, and data breaches and leaks are a latent risk that can happen anytime, with catastrophic consequences such as e-mail, password, social security number and other sensitive and confidential information theft, just like it has happened in recent years to big companies and organizations. Be careful with the platforms and services you choose to use, and make sure you’re trusting good hands with your data, but be also ready to act in case a system breach happens.

Organized cyber crime

One final threat to be aware of during 2018 is organized cyber crime. Cyber criminals have stopped working by themselves or in small groups and have been found to assemble in “hacker groups” and distinct criminal organizations, posing a greater risk for institutions, services and the general public. This is also relevant for countries, given that these cyber criminal organizations also target official institutions and systems. One barrier against these attacks is making sure your devices are protected by a robust and powerful security suite.

OpenAI’s shiny new Atlas browser might have some serious security shortcomings – and it’s not the only one under threat from dangerous spoof attacks

Fake AI sidebars can perfectly imitate real ones to steal secrets, experts warn Malicious extensions need only minimal permissions to cause maximum chaos AI browsers risk turning helpful automation into channels for silent data theft New “agentic” browsers which offer an AI-powered sidebar promise convenience but may widen the window for deceptive attacks, experts have


  • Fake AI sidebars can perfectly imitate real ones to steal secrets, experts warn
  • Malicious extensions need only minimal permissions to cause maximum chaos
  • AI browsers risk turning helpful automation into channels for silent data theft

New “agentic” browsers which offer an AI-powered sidebar promise convenience but may widen the window for deceptive attacks, experts have warned.

Researchers from browser security firm SquareX found a benign-looking extension can overlay a counterfeit sidebar onto the browsing surface, intercept inputs, and return malicious instructions that appear legitimate.

This technique undermines the implicit trust users place in in-browser assistants and makes detection difficult because the overlay mimics standard interaction flows.

How the spoofing works in practice

The attack uses extension features to inject JavaScript into web pages, rendering a fake sidebar that sits above the genuine interface and captures user actions.

Reported scenarios include directing users to phishing sites and capturing OAuth tokens through fake file-sharing prompts. It also recommends commands that install remote access backdoors on victims’ devices.

The consequences escalate quickly when these instructions involve account credentials or automated workflows.

Many extensions request broad permissions, such as host access and storage, that are commonly granted to productivity tools, which reduces the value of permission analysis as a detection method.

Conventional antivirus suites and browser permission models were not designed to recognize a deceptive overlay that never modifies the browser code itself.

As more vendors integrate sidebars across major browser families, the collective attack surface expands and becomes harder to secure.

Users should treat in-browser AI assistants as experimental features and avoid handling sensitive data or authorizing account linkages through them, because doing so can greatly raise the risk of compromise.

Security teams should tighten extension governance, implement stronger endpoint controls, and monitor for abnormal OAuth activity to reduce risk.

The threat also links directly to identity theft when fraudulent interfaces harvest credentials and session tokens with convincing accuracy.

Agentic browsers introduce new convenience while also creating new vectors for social engineering and technical abuse.

Therefore, vendors need to build interface integrity checks, improve extension vetting, and provide clearer guidance about acceptable use.

Until those measures are widely established and audited, users and organizations should remain skeptical about trusting sidebar agents with any tasks involving sensitive accounts.

Security teams and vendors must prioritize practical mitigations, including mandatory code audits for sidebar components and transparent update logs that users and administrators can review regularly.
