O2 Outage – The Cause

During the 6th December 2018, O2 and many other operators than use the O2 network suffered major outages leaving millions of customers with no communications.

Many rumors started to spread saying the company’s networks have been hacked or compromised, O2 quiet quickly squashed that rumor saying that they were not hacked.

24 hours later a high proportion of the network is back up, what was the cause of this major incident, apparently, some Ericson equipment using a faulty version of the software had certificates that expired this rendered them not trustworthy and so security protocols kicked in and shut down the offending equipment.

Ericson has apologised to their customers saying most of the affected customers’ network services have been successfully restored. We are working closely with the remaining customers that are still experiencing issues.

So far 2 days later all seems to be back to normal.

O2 has kindly offered 2 days compensation for the 6th December interruptions.

Beware of Phishing Emails

At this part of the year, we see a sudden increase in Phishing emails.

What are Phishing Emails?

  • They are emails that look like they came from a legitimate company i.e. Banks, Supermarkets, social media plus loads more

Generally, they will ask you to fill out a form requesting all of your details including passwords

What is real and what’s fake and where to look

  • The email address where the email came from is the main give away, in a lot of case it looks like it came from someone’s personal email account, these are people that have had their email address hacked prior to this
  • This next way to spot a fake email, if the email asks you to click a link that leads you to an obscure website name
  • Real companies will never ask you for your password or bank details, especially the CVC code on the back of the card

What are the attachments within the email?

  • Another form of phishing is sending attachments with the email and asking the recipient to open it and fill out the form, if you do happen to open these types of attachment’s in most of the time it’s too late, your computer will be infected then the whole cycle will start again using your email address to send out phishing emails to all of your friends and family
  • If you’re not expecting an email Do not open the attachments claiming to be invoices, bank statements and so on

How would I know if I get infected and what shall I do?

  • The first thing you will notice if that your company may start to be extremely slow at responding, apps and programs take ages to load
  • The other thing you will start getting calls from your friends and family saying that you are sending then spam to them
  • The first thing to do is update your antivirus guard and run a full detailed scan
  • In more extreme cases a full system restore is needed
