Have you ever noticed that your PC or Smart phone has suddenly slowed down to a crawl for no apparent reason?
“How can this be? My anti-virus software is up to date?” you say. It might be busy doing other thing such as attacking other computers around the world as a part of a bot net controlled by hackers, or other guys who wanted just wanted to see the world burn!
You might be a victim tricked to install the malware by many social engineering techniques. The software might show itself as a legitimate product claiming to be a cleaner which would make your PC faster. Once installed, it provides a gateway into your system for malware software developers to install rootkits or botnet software.
So, how this works?
Once the malicious botnet software is installed, it efffectively sets your computer up to receive instructions from a master control terminal that is controlled by the botnet owner who might usually a crazy black-hat hacker or other cyber criminal that purchased the use it to cyber crimes such as DD0S attacks.
It’s like renting out your computer for someone else’s illegal use without your knowledge. Mind boggling isn’t it? A typical botnet may consist of tens of thousands of computers that are all controlled by a single control terminal over the internet. One of such kind is the Mirai Botnet which caused one of the world’s largest DDoS attacks over world leading internet giants such as Dyn Inc. and its DNS service which almost broke major parts of the internet causing Twitter, Instagram servers not reachable in 2016. These attacks are called Distributed Denial of Service Attacks aka DDoS attacks.
Its the acronym for Distributed Denial of Service Attacks. These attacks are caused by many factors. Traditional DDoS attacks are triggered by just one person or computer or it could be as huge as consisting of ten of thousands of computers from a zombie network sending continuous underrated TCP/UDP packets and http requests enough to take down a server or flooding a target site with immense amounts of network traffic. It could also be accidental DoS. Unintentionally many users suddenly trying to access a network or a server at the same time, such a visiting a e-commerce website on black friday or a live viral telecast of a sport. It might also occur by a system becoming infected with a computer virus or worm in a data center.
So how can I save myself from it?
There could be a lot of ways the malware gets installed on the host computer. Many security research companies have levied their paths on working on this field and ensure better security in today’s world! Through some measures one can get rid of this accidental installation of the malicious programs.
1.Get a malware-specific scanner
It might be a reason that your anti-virus couldn’t be able to scan for rootkits or the malicious bot-net software. Consider something like Malwarebytes which is known for finding malware that often evade traditional virus scanners.
2.Get a third-party firewall
Consider getting a third party firewall such as from avast solutions which would analyse the traffic from your computer in addition to the traditional Windows firewall.
3. Avoid fake anti-virus programs
In search for malware protection many end up installing something malicious. Google the product to see false reports and be sure while installing. Never install anything received from unknown sources through e-mail or through a third-party website other than the original developer website. These are often delivery methods for malware developers and malware affiliates.
If you want to be extra sure that the malware infection is gone then you should consider a performing full backup, wipe and reload of your computer to ensure that the malware is gone.
