A newly-created malicious script has become the source of almost half the drive-by download attacks tracked by one security firm.
JSRedir-R accounts for around 43 per cent of all malicious infections found on websites over the last week, according to a study by net security firm Sophos, published on Thursday. The malware crops up with almost six times the frequency of its nearest rival, iFrame-F (which is recorded in seven per cent of attacks).
