 Albabat, Kasseika, Kuiper: New Ransomware Gangs Rise with Rust and Golang

Albabat, Kasseika, Kuiper: New Ransomware Gangs Rise with Rust and Golang

Jan 29, 2024 Ransomware / Malware
Cybersecurity researchers have detected in the wild yet another variant of the Phobos ransomware family known as  Faust . Fortinet FortiGuard Labs, which detailed the latest iteration of the ransomware, said it's being propagated by means of an infection that delivers a Microsoft Excel document (.XLAM) containing a VBA script. "The attackers utilized the Gitea service to store several files encoded in Base64, each carrying a malicious binary," security researcher Cara Lin  said  in a technical report published last week. "When these files are injected into a system's memory, they initiate a file encryption attack." Faust is the latest addition to several ransomware variants from the Phobos family, including Eking, Eight, Elbie, Devos, and 8Base. It's worth noting that Faust was  previously documented  by Cisco Talos in November 2023. The cybersecurity firm described the variant as active since 2022 and "does not target specific industries or re
New CherryLoader Malware Mimics CherryTree to Deploy PrivEsc Exploits

New CherryLoader Malware Mimics CherryTree to Deploy PrivEsc Exploits

Jan 25, 2024 Threat Intelligence / Malware Research
A new Go-based malware loader called  CherryLoader  has been discovered by threat hunters in the wild to deliver additional payloads onto compromised hosts for follow-on exploitation. Arctic Wolf Labs, which discovered the new attack tool in two recent intrusions, said the loader's icon and name masquerades as the legitimate CherryTree note-taking application to dupe potential victims into installing it. "CherryLoader was used to drop one of two privilege escalation tools,  PrintSpoofer  or  JuicyPotatoNG , which would then run a batch file to establish persistence on the victim device," researchers Hady Azzam, Christopher Prest, and Steven Campbell  said . In another novel twist, CherryLoader also packs modularized features that allow the threat actor to swap exploits without recompiling code. It's currently not known how the loader is distributed, but the attack chains examined by the cybersecurity firm show that CherryLoader ("cherrytree.exe") and i

How to Find and Fix Risky Sharing in Google Drive

Mar 06, 2024Data Security / Cloud Security
Every Google Workspace administrator knows how quickly Google Drive becomes a messy sprawl of loosely shared confidential information. This isn't anyone's fault; it's inevitable as your productivity suite is purposefully designed to enable real-time collaboration – both internally and externally.  For Security & Risk Management teams, the untenable risk of any Google Drive footprint lies in the toxic combinations of sensitive data, excessive permissions, and improper sharing. However, it can be challenging to differentiate between typical business practices and potential risks without fully understanding the context and intent.  Material Security, a company renowned for its innovative method of protecting sensitive data within employee mailboxes, has recently launched  Data Protection for Google Drive  to safeguard the sprawl of confidential information scattered throughout Google Drive with a powerful discovery and remediation toolkit. How Material Security helps organ
New iShutdown Method Exposes Hidden Spyware Like Pegasus on Your iPhone

New iShutdown Method Exposes Hidden Spyware Like Pegasus on Your iPhone

Jan 17, 2024 Spyware / Forensic Analysis
Cybersecurity researchers have identified a "lightweight method" called  iShutdown  for reliably identifying signs of spyware on Apple iOS devices, including notorious threats like NSO Group's  Pegasus , QuaDream's  Reign , and Intellexa's  Predator .  Kaspersky, which analyzed a set of iPhones that were compromised with Pegasus, said the infections left traces in a file named "Shutdown.log," a text-based system log file available on all iOS devices and which records every reboot event alongside its environment characteristics. "Compared to more time-consuming acquisition methods like forensic device imaging or a full iOS backup, retrieving the Shutdown.log file is rather straightforward," security researcher Maher Yamout  said . "The log file is stored in a sysdiagnose (sysdiag) archive." The Russian cybersecurity firm said it identified entries in the log file that recorded instances where "sticky" processes, such as

NoaBot: Latest Mirai-Based Botnet Targeting SSH Servers for Crypto Mining

NoaBot: Latest Mirai-Based Botnet Targeting SSH Servers for Crypto Mining

Jan 10, 2024 Server Security / Cryptocurrency
A new Mirai-based botnet called  NoaBot  is being used by threat actors as part of a crypto mining campaign since the beginning of 2023. "The capabilities of the new botnet, NoaBot, include a wormable self-spreader and an SSH key backdoor to download and execute additional binaries or spread itself to new victims," Akamai security researcher Stiv Kupchik said in a report shared with The Hacker News. Mirai , which had its source code leaked in 2016, has been the progenitor of a number of botnets, the most recent being  InfectedSlurs , which is capable of mounting distributed denial-of-service (DDoS) attacks. There are indications that NoaBot could be linked to another botnet campaign involving a Rust-based malware family known as  P2PInfect , which recently received an update to target routers and IoT devices. This is based on the fact that threat actors have also experimented with dropping P2PInfect in place of NoaBot in recent attacks targeting SSH servers, indicating likely at
Researchers Unveil GuLoader Malware's Latest Anti-Analysis Techniques

Researchers Unveil GuLoader Malware's Latest Anti-Analysis Techniques

Dec 09, 2023 Malware / Cyberattack
Threat hunters have unmasked the latest tricks adopted by a malware strain called  GuLoader  in an effort to make analysis more challenging. "While GuLoader's core functionality hasn't changed drastically over the past few years, these constant updates in their obfuscation techniques make analyzing GuLoader a time-consuming and resource-intensive process," Elastic Security Labs researcher Daniel Stepanic  said  in a report published this week. First spotted in late 2019, GuLoader (aka CloudEyE) is an advanced shellcode-based malware downloader that's used to distribute a wide range of payloads, such as information stealers, while incorporating a bevy of sophisticated anti-analysis techniques to dodge traditional security solutions. A  steady stream  of  open-source reporting  into the malware in recent months has revealed the threat actors behind it have continued to improve its ability to bypass existing or new security features alongside other implemented fe
