Many web users in the UK and elsewhere have been the victims of spam attacks and the authorities are doing what they can to tackle the problem.
In a new development, an individual who was involved in a scheme that targeted hundreds of firms with spam containing hidden viruses is facing prison.
Matthew Anderson from Aberdeenshire used his technical knowledge to perform the acts and he operated as a member in a sophisticated international gang of hackers.
The 33-year-old was caught as a result of an investigation by the authorities in Finland and officials from Scotland Yard.
During a hearing at Southwark Crown Court, he pleaded guilty to offences under the Computer Misuse Act.
The criminal activity took place between September 2005 and June 2006.
Along with his accomplices, Mr Anderson had infected computers using viruses attached to unsolicited commercial emails.
Once computers had been affected, he was able to access private and commercial data stored on them and could also activate webcams.
In addition to this, he made copies of private documents, including medical reports, CVs and wills.
Commenting on the gang behind the crimes, Detective Constable Bob Burls from the Met Office’s e-crime unit said: “This organised online criminal network infected huge numbers of computers around the world, especially targeting UK businesses and individuals.
“Matthew Anderson methodically exploited computer users not only for his own financial gain but also violating their privacy. They used sophisticated computer code to commit their crimes.”
However, he went on to say that he would like to reassure the public that the response of the international law enforcement and anti-virus companies is “increasingly sophisticated”.
Indeed, one of the ways in which consumers and businesses can help to protect themselves against attacks of this nature is to invest in spam blockers and other such products.
