Addressing cybersecurity challenges: What’s the best anti-virus advice?

A cybersecurity expert has explained to Digital Journal about the six signs that indicate if you have a computer virus. The advice then expands on how to remove the virus from your device.

In 2022, there were over 1.3 billion malware programmes in existence and 10 percent of these were computer viruses, according to research from the AV-Test Institute. A computer virus may spread from one device to another, take over your software and steal information that can be held at ransom.

Spam emails, instant messaging, file-sharing devices, fake antivirus downloads, unpatched software and infected hardware are the ways in which viruses can infect your computer.

The new advice comes from VPN Overview and it reveals six common symptoms of having a computer virus and how to remove it.

Slow performance

Observing computer performance is one of the first tell-tale signs in terms of whether there is a virus at play. Malicious code typically hijacks computing power and may lead to unbearably slow performance.

Freeze-ups and crashing

There are multiple reasons why a laptop might be crashing. It may be time to restart it, close down one of the many windows you have open or buy a new one – but it could also be a sign your computer has a virus.

Missing files

Malware has been known to delete important data. Once it has infiltrated your device, you may receive multiple pop-ups and notice your files are missing. Do not ignore this – it is a tell-tale sign of a virus that should be taken seriously.

New files appear

In addition to missing files, you may also notice new files mysteriously appearing. Viruses can replace your files with encrypted ones, although these are likely malicious and will only further harm your device if you click on them.

Problems with hardware

Viruses have been known to cause system changes that affect external hardware and accessories. If you can’t get that USB drive and wireless mouse to connect properly or work as it should, for example, it could be a sign of a virus.

Computer operating by itself

Computers are complex machines, but they shouldn’t be executing demands without your…

OnDemand | Hacking the Hacker: Assessing and Addressing Your Organization’s Cyber Defense Weaknesses

Cybercriminals are out there, watching and waiting for the perfect opportunity. They are gathering information about your organization and users, devising the perfect plan to infiltrate your defenses.


But with a strategic approach to cyber defense you can hack the hacker before they strike! In this session, we’ll share insights into their strategies and their motivations. You’ll learn how to use that understanding, along with simple strategies to make your organization a hard target.


In this webinar, Roger A. Grimes, Data-Driven Defense Evangelist at KnowBe4, exposes the mind of a hacker to help you see your cyber risks from the outside in.


In this session you’ll learn:

  • How hackers collect “private” details about your organization and your users

  • The most common root causes that lead to damaging cyber attacks

  • Common mistakes made when designing cyber defenses and how to fix them

  • Data-driven strategies for mitigating your biggest weaknesses

  • Why a strong human firewall is your best, last line of defense

Why NI is vital in addressing RAN threats

Why network intelligence is vital in addressing RAN threats

 

The cybersecurity threat landscape is always evolving, with increasing volume and types of breaches annually. This means CSPs ( Communications Service Providers )need to stay on top of these evolving threats to be better prepared for attackers lurking in the shadows. While every organization will experience some version of a breach, it is important to be prepared for when it happens, despite the fact that mobile networks are well protected against intrusions. To reduce the impact of an attack, it is critical to detect a security incident as soon as it occurs, before it gets a foothold and spreads around in an uncontrolled manner.

In this blog, we will unveil a novel way to detect false base station attacks and finally counter the threat.

What’s new with false base stations?

With telecommunication networks playing an increasingly vital part in our lives, they’ve become an obvious target for malicious actors to launch high-impact attacks. In the RAN domain, which is the most physically accessible part of mobile networks, the limited awareness of the scale and sophistication of the false base station (FBS) threat makes it attractive to malicious actors. Without adequate detection capabilities these threats will remain unknown to service providers. The malicious use of FBSs can have a high impact through techniques such as eavesdropping, tracking, identity spoofing, data and traffic modification, or denial-of-service (DoS) attacks.

The main challenges with detecting false base stations include:

Limited awareness of the scale of the threat

Current methods to detect false base stations are insufficient to understand and quantify the scale of the threat. Examples methods include user equipment (UE)-based detectors, UE applications, crowd-sourced detectors, network-based detectors not using UE measurements, and drive-test based detectors.

Lack of timely and precise detection

Manual threat detection is resource-intensive, limited in coverage (time and place), and prone to human errors and false positives. Even with specialized equipment or sophisticated software, it is hard to do timely and precise…
