Obviously this week the big story has been TalkTalk who it would appear have been hacked and potentially allowed details of 4 million customers into the wrong hands. This is the third large cyber-attack which TalkTalk have received and it is not at present clear why TalkTalk are targeted or who did it but it is far from being the only company that keeps being hit!
Most, if not all, large companies will receive cyber-attacks every day, it is unfortunately the norm. This is the reason why large companies invest in heavily in cyber security but being ahead of the cyber criminals isn’t easy. Around 1 million new malicious programs are created on a daily basis according to security firm Symantec.
It is extremely unlikely that any large company has not received cyber-attacks, it is also very unlikely that any of these large companies haven’t suffered a breach of security due to these attacks at some point. It is only the clever companies that are aware of these breaches and learn from them. It is likely that many companies will not know they have been breached which is much more dangerous than being aware!
Can it be stopped? Very unlikely, unfortunately it is just a case of staying one step ahead of the hackers which in reality is extremely difficult and expensive.
