Last year in 2017, Ransomware attacks were used by cyber-criminals to compromise many businesses, with success.
Ransomware A type of malicious soft
ware. It is designed to block access to a computer system until a sum of money is paid.
This was, in the past, aimed at individuals at home, however is now more than ever being targeted at businesses & larger organisations. Because of the success, cyber-criminals are now looking at other ways to secure their pay-outs.
Phishing emails are from criminals pretending to be from reputable companies. In order to gain personal information, such as passwords and credit card numbers or to place orders causing great loss to the company, they send out attachments and links.
Nowadays, it doesn’t even matter if you know who its from. Cyber-criminals are impersonating banks, reputable organisations and even your friends. If the attachment looks unusual or the link looks funny…it probably is!
Back in 2016 there was a piece of Malware called Mirai. This basically bypassed devices with security by using ones instead that have default username and passwords. (Think standard home routers, baby monitors, IP Cameras, TV’s, home appliances etc.) Once infected, the device is “available” for remote access & control by hackers.
So this year & next, businesses must ensure that the basics are covered. Data management, protection and patching are good places to start. (E.g. Create alerts for anonymous new users, changes in device performance, and regularly auditing passwords)
Its not all doom & gloom…
Businesses must exploit the advantage that they have in knowing what their data network looks like, and use security analytics to spot any anomalies fast.
It’s also vital not to allow internet of things (IoT) devices to simply connect to your network without proper security – Vehicles, wearable’s, health appliances, heating & cooling systems etc.
