Firms using business to business email marketing have been given a further data security warning after over a million addresses were exposed belonging to users of the Washington Post's Jobs web site.
The publication said that the incident took place on June 27th and 28th, with the hackers exploiting a vulnerability in the site.
Personal information or sensitive details were not compromised, however, the breach is a further reminder of the need for businesses to keep on top of their security.
Last month, hacking groups LulzSec and Anonymous were front page news after attacking organizations like Sony and the US Central Intelligence Agency, while the Brazilian Government's website was also targeted.
"We quickly identified the attack and took action to shut it down. We also have implemented additional measures to prevent against a similar attack in the future, and we are pursuing the matter with law enforcement," the Washington Post said in a statement.
