>Kaspersky Labs was probably compromised

Relevant quote:

"Company officials were unable to provide Ars with an estimate of how many megabytes or gigabytes of data were extracted from their network, in part because the custom network connections Duqu used may have bypassed normal logging procedures. The company hasn't ruled out the possibility the attackers obtained Kaspersky Lab source code, but there are no signs they tried to compromise any of Kaspersky's 400 million users."
