+ - Massive DNS Cache Poisoning Hits Brazil-> 1

Submitted by Orome1
Orome1 (1901578) writes "A massive DNS cache poisoning attack attempting to infect users trying to access popular websites is currently under way in Brazil, according to Kaspersky Lab expert Fabio Assolini. Brazil has some big ISPs. Official statistics suggest the country has 73 million computers connected to the Internet, and the major ISPs average 3 or 4 million customers each. If a cybercriminal can change the DNS cache in just one server, the number of potential victims is huge. And that is exactly what has been happening during last week. Users trying to reach Google, YouTube, Facebook and other popular global and local sites were being faced with pop-up windows telling them to install "Google Defence" and similar thematic software or Java applet in order to be able to access the wanted site."

Massive DNS Cache Poisoning Hits Brazil

  • I've been in touch with someone who had a chance to talk with a person from Brazil CERT about this. He shared the view on the types of attacks they've been dealing with, and that the original article was a bit misleading in it's labeling as "cache poisoning." He said it's the same net effect, but a different set of security measures are needed to defend against Kaminsky-style cache-poisoning attempts versus defending against automated cracking of premise routers.
