A new report on the Zeus trojan s evolution shows that the malware was moved from harvesting online banking credentials to controlling botnets and launching distributed denial of service attacks. Ever since the Zeus source code leaked in late 2010, criminals have tailored the trojan to meet their own specific needs. Many of the custom varieties of Zeus are still credential-stealers. Instead of stealing banking credentials, many of them seek login information for cloud services. As variations of Zeus continue emerge with obfuscated payloads, the threat becomes more and more difficult to detect.
