From infiltrating secure data systems to stealing confidential information, hackers stationed all around the world are always ready to aim and fire their next cyberattack onto unsuspecting web users.
About 1 in 4 people are likely to experience a data breach .
Technology brings modern convenience to our daily lives, but it also makes us all vulnerable to online threats. From infiltrating secure data systems to stealing confidential information, hackers stationed all around the world are always ready to aim and fire their next cyberattack at unsuspecting web users.
Malware is an umbrella term for viruses, worms, trojans, ransomware, adware, and spyware. One of the worst types of malware is hybrid attack malware that may be part trojan and part virus. These hybrid attacks can have devastating effects on the end user’s device.
One such hybrid attack was detailed on an episode of RadioLab. The victim’s computer was taken over by malicious files called CryptoWall via a trojan attack and all files on the computer became totally inaccessible. The only message the user could see was a message that informed the user that all the files were encrypted and $500 in Bitcoin were required to get the files back.
Cybercriminals utilize phishing tactics to distribute malicious links and attachments via fraudulent emails or other electronic communication methods. This allows hackers to gain access to user login credentials and other confidential information.
According to the 2019 Verizon Data Breach Investigations Report, almost a third of all data breaches in the past year were phishing-based. Phishing cybercriminals trick unsuspecting users with lookalike sites to places like PayPal or Dropbox to gain login credentials.
Another phishing scam involves ransomware where a user accidentally downloads a malicious file from a seemingly real sender.
Cybercriminals aim to disrupt web traffic and pilfer data which is why connecting to a public, open WiFi network should be done with care.
4. Denial of Service (DoS)
Denial of service attacks typically flood servers, networks, or systems with traffic to overwhelm user resources and bandwidth. Users are rendered completely unable to access infected servers, networks, and systems.
5. Structured Query Language Injection
SQL attacks are characterized by an attacker's malicious code insertion into an SQL server. What’s the risk? This damaging code forces the infected server to reveal otherwise secure information.
What do cybercriminals want?
Every hacker is after something different. It’s important to recognize that there are different types of hackers in order to understand their many varied strategies and methodologies.
Cybercriminals may try to steal computer infrastructure and gain control over PC storage and network resources, for instance. Other hackers want to create a botnet, or a network of malware-infected computers used to commit mass cyber crimes.
There are others who want to disrupt and shut down web servers to render them useless, sometimes for political aims in state-sponsored attacks from other countries.
And finally, some hackers commit identity fraud by pilfering personal information like social security numbers or banking credentials to make unauthorized purchases or to claim certain benefits.
Am I at risk for a cyberattack?
All web and email users are subject to cyberattacks if you don’t use safe web-browsing practices on a daily basis. Stronger protection and wider-spread awareness about the dangers of cybercriminals has only made the modern hacker more creative and sophisticated. And cybercrime isn’t going anywhere: it’s expected to cost the world $6 trillion by the year 2021.
