Source code for proprietary spam bot offered for sale, acts as force multiplier for cybercrime-friendly activity

by

In a professional cybercrime ecosystem, largely resembling that of a legitimate economy, market participants constantly strive to optimize their campaigns, achieve stolen assets liquidity, and most importantly, aim to reach a degree of efficiency that would help them gain market share. Thus, help them secure multiple revenue streams. Despite the increased transparency on the Russian/Easter European underground market — largely thanks to improved social networking courtesy of the reputation-aware cybercriminals wanting to establish themselves as serious vendors — certain newly joining vendors continue being a victim of their market-irrelevant ‘biased exclusiveness’ in terms of the unique value propositon (UVP) presented […]

PHP Backdoor Has Another Backdoor Inside

by

Is there no honor among thieves anymore? The other day I was looking at a remote access Trojan written in the PHP scripting language. The bot loads into memory on a victim’s computer when an unsuspecting user, for example, stumbles upon an iframe pointing to the PHP script embedded in a Web page.
