Symantec boffins reckon it's no longer enough to shield e-mail users from malicious email and that spam and phishing over SMS are now worthy of some decent defences. They've even penned a study to back up the proposition, suggesting that SMS spam could be 97 per cent detectable with a false positive rate as low as 0.02 per cent.
The researchers, from Symantec offices in the UK, Ireland and the US, have published their paper at Arxiv saying that although spam detection in SMS is harder than in e-mail, it can be done.
SMS remains popular – even in an era of over-the-top messaging platforms that want to eat the carriers' lunch by shifting their texts to the data channel – and the paper argues that various habits in SMS make spam detection a problem. They cite “lexical variants”, along with contractions, wordplay and other obfuscations as posing challenges for anyone wanting to detect malicious messages.
