25 August 2016

”Oversharing on networking sites such as google hangouts leave 30% of users vulnerable to cybercrime…”

Unfortunately, any connected device operating in the digital world is increasingly vulnerable to cyber attackers.

A recent scam involving Google hangouts, found that hackers have attempted to install malware on computer, android and apple devices by creating a feature that is included in google hangouts. The strategy is reported to have been used in the form of an email that asks users to download a video conferencing service as a part of google hangouts.

Sadly, once the innocent users had fallen into the attacker’s trap, the malware attempted to download a file which contained Trojan.

What is a Trojan?

A Trojan is a form of malware that is usually disguised as legitimate software to encourage users to click.  Usually employed by hackers, their aim is to gain complete access to user’s systems in order to spy, steal and obtain any sensitive data that may be stored within the computer database.

The popularity of Trojans has boomed and cyber criminals are using them more now than ever. The versatility of Trojans allows them to become unnoticed, affecting innocent users and allowing cyber criminals to gain complete access to the computer.

”27 million different types of malware were reported in 2015 – 21% of these were Trojans”

After a Trojan has been effectively installed on your computer, cyber criminals have full access to your system and activities normally include:

The effect on you…
