Netcraft’s phishing site countermeasures service helps organisations targeted by phishing attacks remove the fraudsters’ forms as quickly as possible.
Recently we became aware that our median times for takedowns are very much better than the industry average calculated by the Anti-Phishing Working Group (APWG) in its most recent Global Phishing Survey. The APWG found that phishing attacks have a median lifetime of 5 hours and 45 minutes. In contrast, banks and other companies using our countermeasures service have experienced a median phishing attack availability of 2 hours and 12 minutes calculated over our most recent 100 takedowns, with the attacks removed in just 38% of the industry average time.
The graph below shows the availability times of our most recent 100 phishing attacks.
The difference between the first and final outages reflect the fact that phishing attacks will sometimes fluctuate up & down on compromised hosts where the fraudster may still have access to the system and be able to replace his content after the site owner removes it. In this scenario it is important to continue monitoring sites for some time after they go offline and restart takedowns if & when the phishing content reappears. For example, 87% of phishing attacks we attended to had their first outage within 24 hours, and 90% had their final outage within 48 hours.
Takedown times do vary significantly from country to country. For example, all of our last 100 takedowns in the US were completed within three days, and 90% had their first outage within 12 hours. In contrast, takedown times in Russia are rather longer, albeit with 90% going down within three days, and 70% having their first outage within twelve hours.
Russia and the US are by no means the long and short of phishing attacks. Phishing attacks we dealt with in the UK & Ireland have a shorter median lifetime than those hosted in the US, whilst phishing attacks we have taken down in Iran have a median lifetime of just under 30 hours, around five times longer than Russia.
In addition to providing fast takedown of the fraudulent content, the countermeasures service is also linked to our phishing site feed, which is licensed by all of the main web browsers, together with many of the largest anti-virus and content filtering products, firewall and network appliance vendors, mail providers, registrars, hosting companies and ISPs. Consequently, as soon as the phishing attack is verified, access to it will be blocked for hundreds of millions of people shortly afterwards, significantly reducing the effectiveness of the attack even before it has been removed.
