Stroganov was caught back in 2006 and sentenced to six years in prison alongside his associate Gerasim Selivanov, but the two were set free after two years. Selivanov was also arrested as part of this week's bust.

While it's unclear why officials chose to act now, cybercrime discussion forum members believe Stroganov and crew were arrested because they committed a cardinal sin in Russia: they targeted people within the country. While authorities are frequently tolerant of cybercriminals targeting the US (and orchestrate hacks themselves), they may have reached a breaking point with a fraudster on their own soil.

It's not certain that the hacker will get a long sentence. We wouldn't count on this deterring other crime rings, even those targeting Russia. However, it could disrupt attempts to swipe your financial info -- if just for a little while.
