    A recent report published by Amtrak’s Office of the Inspector General revealed that an employee of the passenger rail company had been selling passenger data for two decades. The buyer of this data was none other than the Drug Enforcement Agency, which paid the employee $854,460 over the period. Iowa’s senior senator, Check Grassley, sent a letter to the DEA raising serious concerns over the incident. The most significant part of this security breach is the fact that this former employee was able to sell ...

    Targeted attacks are designed to circumvent existing policies and solutions within the target network, thus making their detection a big challenge. As we've stressed in our previous entry about common misconceptions about targeted attacks, there is no one-size-fits-all solution against it; enterprises need to arm themselves with protection that can provide sensors where needed, as well as IT personnel equipped enough to recognize anomalies within the network and to act accordingly.

We saw both tech companies and restaurant chains fall victim to data breaches. We saw ...




    Backdoors are an essential part of targeted attacks, as they allow an external threat actor to exercise control over any compromised machines. These allow the threat actor to collect information and move laterally within the targeted organization. Our investigations into various targeted attacks have showed that a wide variety of tactics are used by backdoors to carry out their routines, as well as remain undetected by network administrators and security products. Over time, these techniques have evolved as more sophisticated defenses become available to network ...

    In our efforts around addressing targeted attacks, we often work with IT administrators from different companies in dealing with threats against their network. During these collaborations, we've recognized certain misconceptions that IT administrators -- or perhaps enterprises in general -- have in terms of targeted attacks. I will cover some of them in this entry, and hope that it will enlighten IT administrators on how they should strategize against targeted attacks, also known as APTs. A targeted attack is a one-time effort Some IT ...
