ShapeShift.io, a Bitcoin exchange website, was hit by a security breach on April 7, which forced the website to suspend its operations indefinitely. The breach compromised the website’s server infrastructure which threatened the integrity of all transactions on the platform. ShapeShift decided to suspend all operations in order to replace the server infrastructure and to make sure nothing is amiss. ShapeShift has been working to fix vulnerabilities, patch possible attack vectors, and resolve customer refunds in a timely manner. As of April 19, ShapeShift’s website is still down for maintenance.
ShapeShift also launched an investigation with the help from Ledger Labs into who the actors behind this event were and how they managed to infiltrate ShapeShift’s systems. On April 13, ShapeShift CEO Erik Voorhees posted on Reddit “Since the investigation into the ShapeShift hack last week started, we had suspicion that someone previously on the team was involved, and that this person assisted an outside hacker. We are confident now that is indeed the case.” Voorhees has not released who this former employee is, but is currently in the midst of a civil suit related to this case.
The IBM X-Force research team has uncovered a new hybrid Trojan, dubbed ‘GozNym’, that is a combination of the known Nymaim dropper and Gozi financial Malware. The Malware has been used to attack 24 different banks, credit unions, e-commerce platforms and retail banks in the United States and Canada since the start of April, and purportedly has stolen over $4 million from its victims. This Malware is especially dangerous because it targets the actual customers, lying dormant on their computers until the user logs into their bank account, at which point the Trojan steals their sensitive information. The new hybrid Malware leverages the stealth and persistence of the Nymaim dropper and parts from the Gozi ISFB Malware enable the Trojan to commit fraud via infected Internet browsers.
According to IBM, the ‘GozNym’ sample they investigated can currently be detected by most major antivirus vendors based on its signature. Despite this, it is clear that bad actors are constantly searching for new zero-day exploits to leverage due to the increased number of modifications and variations being observed and the fact that security bypass and antivirus evasion mechanisms are constantly changing.
