Three Ways Varonis Helps You Fight Insider Threats

Three Ways Varonis Helps You Fight Insider Threats

Nov 15, 2023 Insider Threat / Risk Management
What do basketball teams, government agencies, and car manufacturers have in common? Each one has been breached, having confidential, proprietary, or private information stolen and exposed by insiders. In each case, the motivations and methods varied, but the risk remained the same: insiders have access to too much data with too few controls. Insider threats  continue to prove difficult for organizations to combat because — unlike an outsider — insiders can navigate sensitive data undetected and typically without suspicion. Cybersecurity is not the first industry to tackle insider threats, however. Espionage has a long history of facing and defending against insiders by using the "CIA Triad" principles of confidentiality, integrity, and availability. Varonis' modern cybersecurity answer to insider risk is the data security triad of "sensitivity, access, and activity." Using these three dimensions of data security, you can help reduce the risk and impact of an insider attack. ...
Alert: OracleIV DDoS Botnet Targets Public Docker Engine APIs to Hijack Containers

Alert: OracleIV DDoS Botnet Targets Public Docker Engine APIs to Hijack Containers

Nov 14, 2023 Cloud Security / Malware
Publicly-accessible Docker Engine API instances are being targeted by threat actors as part of a campaign designed to co-opt the machines into a distributed denial-of-service (DDoS) botnet dubbed  OracleIV . "Attackers are exploiting this misconfiguration to deliver a malicious Docker container, built from an image named 'oracleiv_latest' and containing Python malware compiled as an ELF executable," Cado researchers Nate Bill and Matt Muir  said . The malicious activity starts with attackers using an HTTP POST request to Docker's API to retrieve a malicious image from Docker Hub, which, in turn, runs a command to retrieve a shell script (oracle.sh) from a command-and-control (C&C) server. Oracleiv_latest  purports to be a MySQL image for docker and has been pulled 3,500 times to date. In a perhaps not-so-surprising twist, the image also includes additional instructions to fetch an XMRig miner and its configuration from the same server. That said, the clo...
New Ransomware Group Emerges with Hive's Source Code and Infrastructure

New Ransomware Group Emerges with Hive's Source Code and Infrastructure

Nov 13, 2023 Cyber Threat / Malware
The threat actors behind a new ransomware group called  Hunters International  have acquired the source code and infrastructure from the now-dismantled Hive operation to kick-start its own efforts in the threat landscape. "It appears that the leadership of the Hive group made the strategic decision to cease their operations and transfer their remaining assets to another group, Hunters International," Martin Zugec, technical solutions director at Bitdefender,  said  in a report published last week. Hive, once a prolific ransomware-as-a-service (RaaS) operation, was  taken down  as part of a coordinated law enforcement operation in January 2023. While it's common for ransomware actors to regroup, rebrand, or disband their activities following such seizures, what can also happen is that the core developers can pass on the source code and other infrastructure in their possession to another threat actor. Reports about Hunters International as a possible Hi...

The Hidden Risks of SaaS: Why Built-In Protections Aren't Enough for Modern Data Resilience

The Hidden Risks of SaaS: Why Built-In Protections Aren't Enough for Modern Data Resilience

Jun 26, 2025Data Protection / Compliance
SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...
HelloKitty Ransomware Group Exploiting Apache ActiveMQ Vulnerability

HelloKitty Ransomware Group Exploiting Apache ActiveMQ Vulnerability

Nov 02, 2023 Threat Intelligence / Vulnerability
Cybersecurity researchers are warning of suspected exploitation of a recently disclosed critical security flaw in the Apache ActiveMQ open-source message broker service that could result in remote code execution. "In both instances, the adversary attempted to deploy ransomware binaries on target systems in an effort to ransom the victim organizations," cybersecurity firm Rapid7  disclosed  in a report published Wednesday. "Based on the ransom note and available evidence, we attribute the activity to the HelloKitty ransomware family, whose source code was leaked on a forum in early October." The intrusions are said to involve the exploitation of  CVE-2023-46604 , a remote code execution vulnerability in Apache ActiveMQ that allows a threat actor to run arbitrary shell commands. It's worth noting that the  vulnerability  carries a CVSS score of 10.0, indicating maximum severity. It has been  addressed  in ActiveMQ versions 5.15.16, 5.16.7, 5.17.6, ...
Turla Updates Kazuar Backdoor with Advanced Anti-Analysis to Evade Detection

Turla Updates Kazuar Backdoor with Advanced Anti-Analysis to Evade Detection

Nov 01, 2023 Cyber Threat / Malware
The Russia-linked hacking crew known as Turla has been observed using an updated version of a known second-stage backdoor referred to as Kazuar. The new findings come from Palo Alto Networks Unit 42, which is tracking the adversary under its constellation-themed moniker  Pensive Ursa . "As the code of the upgraded revision of Kazuar reveals, the authors put special emphasis on Kazuar's ability to operate in stealth, evade detection and thwart analysis efforts," security researchers Daniel Frank and Tom Fakterman  said  in a technical report. "They do so using a variety of advanced anti-analysis techniques and by protecting the malware code with effective encryption and obfuscation practices." Pensive Ursa, active since at least 2004, is attributed to the Russian Federal Security Service (FSB). Earlier this July, the Computer Emergency Response Team of Ukraine (CERT-UA)  implicated  the threat group to attacks targeting the defense sector in Ukraine and East...
