Zscaler's ThreatLabz research team is tracking a new botnet dubbed DreamBus that's installing the XMRig cryptominer on powerful, enterprise-class Linux and Unix systems with the goal of using their computing power to mine monero.
Microsoft researchers are offering fresh details on the SolarWinds hackers' extensive efforts to remain hidden, which gave them more time to fully penetrate systems, move laterally through networks and exfiltrate data in follow-on attacks.
Ransomware dominated the cybercrime landscape in 2020 and looks set to do so again this year, as criminals seek fresh new ways to make victims pay. Experts predict gangs will double down on whatever works, which lately includes data exfiltration.
Security firm FireEye has released a free auditing and remediation tool on GitHub that it says can help organizations determine if the hacking group that targeted SolarWinds used similar techniques within their network to gain access to Microsoft Office 365 accounts.
Researchers at Check Point Research are tracking a new botnet dubbed "FreakOut" that's targeting vulnerabilities in Linux systems. The malware is creating a malicious network that has the potential to launch DDoS attacks.
Symantec Threat Intelligence says it's uncovered another malware variant used in the SolarWinds supply chain hack - a loader nicknamed "Raindrop" that apparently was used to deliver Cobalt Strike, a legitimate penetration testing tool, to a handful of targets.
The U.S. Capitol siege and the impeachment of President Trump are being exploited for disinformation purposes ahead of Inauguration Day by Russia, Iran and China, a U.S. joint threat assessment reportedly warns. But in terms of violence, domestic extremists are the principal threat.
A new leaks site claims to be selling data from Cisco, FireEye, Microsoft and SolarWinds that was stolen via the SolarWinds supply chain attack. Security experts question whether the offer is legitimate and note that it parallels previous efforts, including by Russia, designed to foil hack attack attribution.
A recently identified mobile remote access Trojan dubbed "Rogue," which exploits Google's Firebase development platform, targets Android devices to exfiltrate personal data and can deliver other malware, according to Check Point Research. The RAT is being offered for sale or rent in darknet forums.
Investigators probing the supply chain attack that hit SolarWinds say attackers successfully hacked the company's Microsoft Visual Studio development tools to add a backdoor into Orion network monitoring security software builds. They warn that other vendors may have been similarly subverted.
The "Sunburst" backdoor deployed in the breach of SolarWinds' Orion network monitoring tool uses some of the same code found in the "Kazuar" backdoor, which security researchers have previously tied to Russian hackers, the security firm Kaspersky reports.
