Hackers now pick tools from script kiddies’ toybox – report
Infosec 2012 Hackers are increasingly turning to automated software tools to launch attacks.
According to research from Imperva, more than 60 per cent of SQL injection attacks and as many as 70 per cent of Remote File Inclusion attacks (the two most common attack types) are automated. Remote File Inclusion attacks allows hackers to plant back doors on PHP-based websites.
Tools like Havij and SQLMap are used by miscreants to probe for vulnerabilities and execute SQL injection attacks. These tools also employ techniques to evade detection, such as periodically changing headers or splitting attacks through controlled hosts to avoid black-listing. In the past, using attack tools was purely for script kiddies but these attitudes are changing, according to Rob Rachwald, director of security strategy at Imperva.
Automatic attack tools aren’t just for the clueless anymore, he says. These tools can be used to attack more applications and exploit more vulnerabilities than any manual method possibly could, making them a useful adjunct for even skilled attackers. “Automated tools are becoming better quality. Both experienced and inexperienced hackers use them but experienced hackers use them with more finesse,” Rachwald explained.
By contrast, organisations still struggle to embrace automatic defences, often deploying technologies such as intrusion prevention systems in “alert only” mode. Rachwald argued that too much focus was being placed on attacks based on spear-phishing and malware (ie, advanced persistent threat attacks) at the expense of overlooking more commonplace assaults, such as SQL injection attacks.
Automated attacks have specific traffic characteristics such as rate, rate change and volume, all factors which can be used to fingerprint and block automated attacks. For example, IP addresses associated with automated attacks can be blocked. ®
Havij means “carrot” in Farsi, which is also the slang word for penis in Iran. The tool was developed by an Iranian blackhat with an obvious taste for crude humour. SQLMap, unlike Havij, is a command-line tool.
