In today's part of our regular column, in which we deal with significant events from the history of technology, we remember the presentation of one of the most important technological inventions - the telephone device. In the second part of the article, we will then recall the spread of an e-mail that promised photos of tennis player Anna Kurnikova, but only spread malicious software.

Alexander Graham Bell demonstrating the telephone (1877)

On February 12, 1877, scientist and inventor Alexander Graham Bell demonstrated the first telephone on the grounds of Salem Lyceum Hall. The telephone patent dated back to February of the previous year and ended up being the highest-grossing patent ever filed. In January 1876, AG Bell called his assistant Thomas Watson from the ground floor to the attic, and in 1878 Bell was already attending the ceremonial opening of the first telephone exchange in Newhaven.

The "Tennis" Virus (2001)

On February 12, 2001, an e-mail containing a photo of the famous tennis player Anna Kournikova began to circulate on the Internet. In addition, the email message also contained a virus created by Dutch programmer Jan de Wit. Users were prompted to open the image in the email, but it was actually a computer virus. The malicious software subsequently attacked the MS Outlook address book after its launch, so that the message was automatically sent to all contacts on the list. The virus was created just one day before it was sent out. Reports on how the perpetrator was apprehended differ from each other - some sources say that de Wit turned himself in to the police, while others say that he was discovered by FBI agent David L. Smith.
