Cyber-crime is estimated to cost more than $6 trillion annually by 2021. Companies face real threats from real criminals daily. Network security companies can help protect company’s data from these criminals.

Here are a few common threats you should know about:

Spear Phishing is the attempt to steal individual financial account credentials. This is different from phishing which is targeted to groups of people. Spear Phishers target people who put sensitive information on the internet. The attackers view profiles while scanning networking sites gaining email addresses, friends lists, geographic locations and purchasing behaviors and histories. With this information, the attacker can disguise as a friend and send fraudulent messages. They could ask for usernames and passwords to access confidential websites, typically explaining they are in an emergency and need help fast.

Ransomware is an especially vicious form of malware. Criminals send out emails with a malicious link or attachment that appears legitimate but opens a computer virus and holds the data on the device for ransom. Criminals who hold files for ransom often threaten to publish stolen data or block access to it until the ransom is paid.

Not all ransomware or phishing attacks will have the following indicators, but they’re common nonetheless:

* Strange spellings or errors in the email
* Official looking (but slightly off) sender’s email address
* Generic addressee line
* Link with a strange URL (hover, never click)
* Unknown attachment with strange file extensions

In many cases, it may take only one malicious email being successful to provide attackers with a doorway into the back end of a target network and a route to significant damage. Network security companies can teach you tips to avoid attacks such as: never click on email attachments or website links from unknown senders.

Network Printers – less than 2% of the 600 million printers in the world are unsecured. Criminals can hack into the operating system on the printers easily from mobile phones gathering information. Further, they send fraudulent emails with malware to unsuspecting people. For example, the email may look like a legitimate gift certificate with instructions to print. Afterwards, the hacker has access to unencrypted data because most companies don’t think about malware protection for their printers.

Wireless networks are vulnerable to hackers because data is transmitted through broadcast radio technology instead of dedicated cable. There is no firewall installed because the networking transmissions are broadcasted indiscriminately. Intruders can pick up signals as far as 500 meters away. Be safe by securing sensitive personal and financial information. Network Security Companies can help you take steps to secure your router, such as turning off remote management features; changing pre-set passwords; changing the default name of the router and keeping the software up to date.

Mobile Phone use in a rental car is also a vulnerability. Using the rental car’s hands-free system stores contacts called, for example. If the data isn’t deleted from the car’s system, the next person who rents the car can access the data.
