Abstract:

In a persistent threat, the attacker often penetrates a system but exploits information captured there elsewhere at a throttled rate to avoid detection. In some cases, the attacker even takes measures to protect the penetrated system from other attackers to avoid the detailed inspection that often accompanies the detection of a compromise. I will describe one particular kind of situation in which a single point of compromise is used to extract consumer financial information that is then used elsewhere to commit fraud. This kind of attack can be difficult to detect and hard to trace. In fact, however, detailed examination of transaction histories across thousands to millions of accounts can provide a very sensitive indicator of such activity and can often pin-point the original point of compromise. The detection technique that I will describe has very broad applicability across many problems that involve sequences of symbols and has produced state-of-art results in genomics, fraud detection, text analysis, retail recommendations and predicting attrition and profitability. The specific case that I describe in this talk is also interesting since the technique was initially developed using synthetic data which emulated real data closely enough that a fraud ring was detected the first time out.
