Cyber criminals don't go on holiday – as security experts at G DATA have noticed in recent years. But what are they targeting? Bank and credit card data are particularly popular: in special underground forums they are monetized or immediately misused for other criminal activities.
"In addition to using security software, anyone not wanting to fall victim to cyber criminals should keep their entire system fully up-to-date at all times. This last point is usually ignored and frequently enables attackers to infect computers through vulnerabilities in installed programs that have not been mitigated," explains Ralf Benzmüller, head of G DATA SecurityLabs. "Holidaymakers should also thoroughly check online offers and verify the reputation of the provider." Spam emails with holiday offers should generally be deleted. Under no circumstances should recipients open file attachments or click on links. The expert also strongly advises against responding to spam email: "By doing so users are indicating to the criminals that the email address is being actively used."
