WAV Audio Files Are Now Being Used To Hide Malicious Code

An nameless reader quotes a report from Ars Technica: IBM X-Drive, the corporate’s safety unit, has revealed a report of a brand new type of “wiper” malware related to menace teams in Iran and utilized in a damaging assault towards firms within the Center East. The pattern was found in a response to an assault on what an IBM spokesperson described as “a brand new surroundings within the [Middle East] — not in Saudi Arabia, however one other regional rival of Iran.” Dubbed ZeroCleare, the malware is “a possible collaboration between Iranian state-sponsored teams,” in line with a report by IBM X-Drive researchers. The assaults have been focused towards particular organizations and used brute-force password assaults to achieve entry to community assets. The preliminary part of the assaults was launched from Amsterdam IP addresses owned by a gaggle tied to what IBM refers to because the “ITG13 Group” — also referred to as “Oilrig” and APT34. One other Iranian menace group could have used the identical addresses to entry accounts previous to the wiper marketing campaign.

Along with brute power assaults on community accounts, the attackers exploited a SharePoint vulnerability to drop internet shells on a SharePoint server. These included China Chopper, Tunna, and one other Energetic Server Pages-based webshell named “extensions.aspx,” which “shared similarities with the ITG13 instrument often known as TWOFACE/SEASHARPEE,” the IBM researchers reported. Additionally they tried to put in TeamViewer distant entry software program and used a modified model of the Mimikatz credential-stealing instrument — obfuscated to cover its intent — to steal extra community credentials off the compromised servers. From there, they moved out throughout the community to unfold the ZeroCleare malware. “Whereas X-Drive IRIS can not attribute the exercise noticed in the course of the damaging part of the ZeroCleare marketing campaign,” the researchers famous, “we assess that high-level similarities with different Iranian menace actors, together with the reliance on ASPX internet shells and compromised VPN accounts, the hyperlink to ITG13 exercise, and the assault aligning with Iranian targets within the area, make it doubtless this assault was executed by a number of Iranian menace teams.”
