Researchers have identified functional similarities between a malicious component used in the Raspberry Robin infection chain and a Dridex malware loader, further strengthening the operators' connections to the Russia-based Evil Corp group.   The findings suggest that "Evil Corp is likely using Raspberry Robin infrastructure to carry out its attacks," IBM Security X-Force researcher Kevin Henson said in a Thursday analysis.   Raspberry Robin (aka QNAP Worm), first discovered...

Iranian state-sponsored actors are leaving no stone unturned to exploit unpatched systems running Log4j to target Israeli entities, indicating the vulnerability's long tail for remediation.   Microsoft attributed the latest set of activities to the umbrella threat group tracked as MuddyWater (aka Cobalt Ulster, Mercury, Seedworm, or Static Kitten), which is linked to the Iranian intelligence apparatus, the Ministry of Intelligence and Security (MOIS).   The attacks are notable...

Cyberattackers have compromised the internal systems of LastPass, making off with source code and intellectual property.   The password management company said it detected anomalous activity in its development environment two weeks ago. After digging into the forensic data, investigators determined that someone (or someones) compromised a developer account to gain access to the network, taking "portions of source code and some proprietary LastPass technical information," according...

According to the Cloud Security Alliance's 2021 report, "State of Cloud Security Concerns, Challenges and Incidents," 41% of participants were "unsure" whether they had experienced a cloud security incident in the recent year.   And that percentage doubled since 2019.   Cloud security threats are on the rise, and more organizations are using two or more public cloud providers to meet organizational needs. These cloud environments typically host sensitive...

The malware loader known as Bumblebee is being increasingly co-opted by threat actors associated with BazarLoader, TrickBot, and IcedID in their campaigns to breach target networks for post-exploitation activities.   "Bumblebee operators conduct intensive reconnaissance activities and redirect the output of executed commands to files for exfiltration," Cybereason researchers Meroujan Antonyan and Alon Laufer said in a technical write-up.   Bumblebee first came to light in March 2022 when...

A security feature bypass vulnerability has been uncovered in three signed third-party Unified Extensible Firmware Interface (UEFI) boot loaders that allow bypass of the UEFI Secure Boot feature.   "These vulnerabilities can be exploited by mounting the EFI System Partition and replacing the existing bootloader with the vulnerable one, or modifying a UEFI variable to load the vulnerable loader instead of the existing one," hardware security firm...
