Facebook Like Farming Scams

25/05/2015

I’ve seen a few like scams doing the rounds. They usually take the form of competition. However, there is no prize.

They usually follow the same pattern of “like and share”. They will offer “prizes” such as: a cruise, airline tickets, a phone… There is no prize. They don’t exist. The promised prizes are just the bait used to hook people into liking the page and sharing the content.

11/09/2014

A list of 5 million GMail addresses and passwords were recently published on a Russian bitcoin forum. Security experts say that the source was most likely from a phishing attack rather than Google being hacked. The list appears to be old. There is no need to panic

Heartbleed

16/04/2014

Heartbleed still continues to ripple through the internet. Heartbleed was a hole in Open SSL that allowed some people access to small amounts of data during a secure http transaction. It is not so much a break in and burglary attempt. It is more of an open window where someone can reach in a take a few small things. That is not to say that it is nothing to worry about. It is.

Mashable has a list of sites affected by Heartbleed.

Warning! Domain name scam strikes again.

2/04/2013

We received a letter from a company called Domain Renewal Group. The letter looks like a renewal notice for a soon to expire domain. It has the appearance of an invoice. It is not. It is a scam. If get one of these in the mail, send to the recycling.

It operates by looking like an invoice. If you are a time-pressed business, you could easily just pay it without giving any thought. They offer to renew a .com domain for AUD$75 and make it look cheap. By way of comparison, here is a sample of typical .com registration costs:

Google Adwords Phishing Scam

19/12/2011

We recently received an email asking us to to update our Google AdWords. This is clearly a phishing scam that has nothing to do with Google. This makes a change from the regular banking or eBay ones we get.

The link says http://adwords.google.com/select/login while it really points to http://www.adwords.google.com.0lks.cn/select/Login. Note the extra bit in the URL.

Don't get caught out.

Avoid the Attack of the Killer Virii

2/09/2010

The nature of the computer virus has changed over the years. It used to be that the humble floppy disk was the vector for transmission. Now that has changed . The number one vector is email.

Some of the new viruses can be quite sinister. Some run inside the computer collecting keystrokes and details such credit card numbers. Others turn machines into "zombies: sending out spam. Some viruses are political, designed to attack major corporations such as Microsoft. In fact Microsoft has often been a target. A lot of viruses have been written exploiting some security holes in the code. Once a security hole has been discovered Microsoft issue a patch pretty quickly.

The Scourge of Spam

23/03/2010

Spam used to just a nuisance. A little bit of junk email here and there. Hit delete and forget it. Now it is turning into a major headache. Some spam contains viruses. A lot is just plain fraud. The fraud ranges from spam proporting to be from your bank asking you to click a fake link to supply your net banking login and password, to the Nigerian scams, to advertising products that have doubtful claims.

A lot of spam is theft. Many spammers scour the internet looking for open relay mail servers. They then send a flood of spam and move on the next victim. A kind of internet mugging.
