are a class of malware
destined for one specific organization or industry. A type of crimeware
, these threats are of particular concern because they are designed to capture sensitive information. Targeted attacks may include threats delivered via SMTP e-mail, port attacks, zero day attack
vulnerability exploits or phishing
messages. The home user is the most targeted sector. Financial industries are the second most targeted sector, most likely because cybercriminals desire to profit from the confidential, sensitive information the financial industry IT infrastructure houses. Similarly, online brokerage accounts have also been targeted by such attacks.
The impact of targeted attacks can be far-reaching. In addition to regulatory sanctions imposed by HIPAA
, Sarbanes-Oxley, the Gramm-Leach-Bliley Act and other laws, they can lead to the loss of revenue, focus and corporate momentum. They not only expose sensitive customer data, but damage corporate reputations and incur potential lawsuits.
Detection and prevention
In contrast to a widespread spam
attack, which are widely noticed, because targeted attacks are only sent to a limited number of organizations, these crimeware threats tend to not be reported and thus elude malware scanners.
- Multiple-layered pattern scanning
- Traffic-origin scanning. Targets known bad locations or traffic anomalies.
- Behavior observation. Including desktop emulator solutions and virtual machine behavior analysis.
- In one instance, Trojan horses were used as a targeted threat so that Israeli companies could conduct corporate espionage on each other.
- The Hotword Trojan3, the Ginwui4 and the PPDropper Trojans are additional examples of Trojans used for corporate espionage.
- Targeted destination attacks use harvested IP addresses to send messages directly to recipients without an MX record lookup. It aims for specific sites and users by defeating hosted protection services and internal gateways to deliver e-mail with malicious payloads.
