There is a new wave of phishing scams to try and give your credit card details or passwords to the unwary. Thankfully, while some are worryingly convincing, others are surprisingly poor. The Mimecast cybersecurity company has found a rise in scams using the promise of tax refunds to encourage people to give up their personal information, including their name, address, telephone number and card details. The growth in scams is likely to coincide with the deadline of 31 January to submit HMRC self-assessment tax returns. In the United Kingdom, around 12 million people are required this year to complete a self-evaluation tax return, so such schemes can seem like an enticing proposition. Fortunately, many of these scams have stylistic oddities and grammatical howlers, which should guard attentive readers. Spelling errors, titles for government agencies that do not sound right and other design issues will function like alarm bells. Another tip is that they obviously come from non-official email addresses. Nevertheless, other schemes are far more difficult to distinguish from the facts and to mimic the look and feel of tax authorities successfully. Whether they are good or bad, “unfortunately, attacks like these do work and that’s why they continue to grow in popularity,” said Carl Wearn, Mimecast’s e-crime boss.
