Atlassian Confluence Flaw Being Used to Deploy Ransomware and Crypto Miners

Atlassian Confluence Flaw Being Used to Deploy Ransomware and Crypto Miners

Jun 18, 2022
A recently patched  critical security flaw  in Atlassian Confluence Server and Data Center products is being actively weaponized in real-world attacks to drop cryptocurrency miners and ransomware payloads. In at least two of the Windows-related incidents observed by cybersecurity vendor Sophos, adversaries exploited the vulnerability to deliver Cerber ransomware and a  crypto miner  called z0miner on victim networks. The bug ( CVE-2022-26134 , CVSS score: 9.8), which was  patched  by Atlassian on June 3, 2022, enables an unauthenticated actor to inject malicious code that paves the way of remote code execution (RCE) on affected installations of the collaboration suite. All supported versions of Confluence Server and Data Center are affected. Other notable malware pushed as part of disparate instances of attack activity include Mirai and Kinsing bot variants, a rogue package called  pwnkit , and Cobalt Strike by way of a web shell deployed after gaining an initial foothold into the
New Unpatched Horde Webmail Bug Lets Hackers Take Over Server by Sending Email

New Unpatched Horde Webmail Bug Lets Hackers Take Over Server by Sending Email

Jun 01, 2022
A new unpatched security vulnerability has been disclosed in the open-source Horde Webmail client that could be exploited to achieve remote code execution on the email server simply by sending a specially crafted email to a victim. "Once the email is viewed, the attacker can silently take over the complete mail server without any further user interaction," SonarSource said in a report shared with The Hacker News. "The vulnerability exists in the default configuration and can be exploited with no knowledge of a targeted Horde instance." The issue, which has been assigned the CVE identifier  CVE-2022-30287 , was reported to the vendor on February 2, 2022. The maintainers of the Horde Project did not immediately respond to a request for comment regarding the unresolved vulnerability. At its core, the issue makes it possible for an authenticated user of a Horde instance to run malicious code on the underlying server by taking advantage of a quirk in how the client
How to Find and Fix Risky Sharing in Google Drive

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

Ukrainian Hacker Jailed for 4-Years in U.S. for Selling Access to Hacked Servers

May 16, 2022
A 28-year-old Ukrainian national has been sentenced to four years in prison for siphoning thousands of server login credentials and selling them on the dark web for monetary gain as part of a credential theft scheme. Glib Oleksandr Ivanov-Tolpintsev , who pleaded guilty to his offenses earlier this February, was arrested in Poland in October 2020, before being  extradited to the U.S.  in September 2021. The illegal sale involved the trafficking of login credentials to servers located across the world and personally identifiable information such as dates of birth and Social Security numbers belonging to U.S. residents on a darknet marketplace. The unnamed site purportedly offered over 700,000 compromised servers for sale, including at least 150,000 in the U.S. alone. Believed to have been operational from around October 2014, the underground marketplace was seized by law enforcement authorities on January 24, 2019, according to court documents. This exactly coincides with the dism

Latest Atlassian Confluence Flaw Exploited to Breach Jenkins Project Server

Latest Atlassian Confluence Flaw Exploited to Breach Jenkins Project Server

Sep 07, 2021
The maintainers of Jenkins—a popular open-source automation server software—have disclosed a security breach after unidentified threat actors gained access to one of their servers by exploiting a recently disclosed vulnerability in Atlassian Confluence service to install a cryptocurrency miner. The "successful attack," which is believed to have occurred last week, was mounted against its Confluence service that had been deprecated since October 2019, leading the team to take the server offline, rotate privileged credentials, and reset passwords for developer accounts. "At this time we have no reason to believe that any Jenkins releases, plugins, or source code have been affected," the company  said  in a statement published over the weekend. The disclosure comes as the U.S. Cyber Command  warned  of ongoing mass exploitation attempts in the wild targeting a now-patched critical security vulnerability affecting Atlassian Confluence deployments. Tracked as CVE-2
New APT Hacking Group Targets Microsoft IIS Servers with ASP.NET Exploits

New APT Hacking Group Targets Microsoft IIS Servers with ASP.NET Exploits

Aug 02, 2021
A new highly capable and persistent threat actor has been targeting major high-profile public and private entities in the U.S. as part of a series of targeted cyber intrusion attacks by exploiting internet-facing Microsoft Internet Information Services ( IIS ) servers to infiltrate their networks. Israeli cybersecurity firm Sygnia, which identified the campaign, is tracking the advanced, stealthy adversary under the moniker "Praying Mantis" or "TG2021." "TG1021 uses a custom-made malware framework, built around a common core, tailor-made for IIS servers. The toolset is completely volatile, reflectively loaded into an affected machine's memory and leaves little-to-no trace on infected targets," the researchers  said . "The threat actor also uses an additional stealthy backdoor and several post-exploitations modules to perform network reconnaissance, elevate privileges, and move laterally within networks."  Besides exhibiting capabilities
Wormable DarkRadiation Ransomware Targets Linux and Docker Instances

Wormable DarkRadiation Ransomware Targets Linux and Docker Instances

Jun 22, 2021
Cybersecurity researchers are sounding the alarm bell over a new ransomware strain called " DarkRadiation " that's implemented entirely in Bash and targets Linux and Docker cloud containers, while banking on messaging service Telegram for command-and-control (C2) communications. "The ransomware is written in  Bash  script and targets Red Hat/CentOS and Debian Linux distributions," researchers from Trend Micro  said  in a report published last week. "The malware uses OpenSSL's AES algorithm with CBC mode to encrypt files in various directories. It also uses Telegram's API to send an infection status to the threat actor(s)." As of writing, there's no information available on the delivery methods or evidence that the ransomware has been deployed in real-world attacks. The findings come from an analysis of a collection of hacking tools hosted on the unidentified threat actor's infrastructure (IP address "185.141.25.168") in a
Researchers Find Vulnerabilities in Microsoft Azure Cloud Service

Researchers Find Vulnerabilities in Microsoft Azure Cloud Service

Oct 08, 2020
As businesses are increasingly migrating to the cloud, securing the infrastructure has never been more important. Now according to the latest research, two security flaws in Microsoft's Azure App Services could have enabled a bad actor to carry out server-side request forgery ( SSRF ) attacks or execute arbitrary code and take over the administration server. "This enables an attacker to quietly take over the App Service's git server, or implant malicious phishing pages accessible through Azure Portal to target system administrators," cybersecurity firm Intezer said in a report published today and shared with The Hacker News. Discovered by  Paul Litvak of Intezer Labs, the flaws were reported to Microsoft in June, after which the company subsequently addressed them. Azure App Service is a cloud computing-based platform that's used as a hosting web service for building web apps and mobile backends. When an App Service is created via Azure, a new Docker env
Cybercriminals Are Using Legit Cloud Monitoring Tools As Backdoor

Cybercriminals Are Using Legit Cloud Monitoring Tools As Backdoor

Sep 09, 2020
A cybercrime group that has previously struck Docker and Kubernetes cloud environments has evolved to repurpose genuine cloud monitoring tools as a backdoor to carry out malicious attacks, according to new research. "To our knowledge, this is the first time attackers have been caught using legitimate third party software to target cloud infrastructure," Israeli cybersecurity firm Intezer said in a Tuesday analysis. Using software called Weave Scope , which is used as a visualization and monitoring tool for Docker and Kubernetes services, the TeamTNT threat actor not only mapped the cloud environment of their victims but also executed system commands without having to deploy malicious code on the target server explicitly. TeamTNT has been active at least since late April this year, directing their attacks on misconfigured Docker ports to install a cryptocurrency mining malware and a Distributed Denial-of-Service (DDoS) bot. Then last month , the crypto-mining gan

Louisiana State Government Hit by Ransomware Attack Forcing Server Shutdowns

Nov 19, 2019
Targeted ransomware attacks on banking and finance, government , healthcare , and critical infrastructure are on the rise, with the latest victim being the state government of Louisiana. The state government of Louisiana was hit by a large-scale coordinated ransomware attack yesterday, which forced the state to take several state agency servers offline, including government websites, email systems, and other internal applications, to mitigate the risk of the malware's infection from spreading. The Monday's ransomware attack resulted in the subsequent shutdown of a majority of large state agencies, including the Office of the Governor, the Office of Motor Vehicles, the Department of Health, the Department of Children and Family Services, and the Department of Transportation and Development, among others. Louisiana Gov. John Bel Edwards revealed the incident in a series of tweets, saying that he had activated the state's cybersecurity team in response to the cyber
Multiple Code Execution Flaws Found In PHP Programming Language

Multiple Code Execution Flaws Found In PHP Programming Language

Sep 06, 2019
Maintainers of the PHP programming language recently released the latest versions of PHP to patch multiple high-severity vulnerabilities in its core and bundled libraries, the most severe of which could allow remote attackers to execute arbitrary code and compromise targeted servers. Hypertext Preprocessor, commonly known as PHP, is the most popular server-side web programming language that powers over 78 percent of the Internet today. The latest releases under several maintained branches include PHP version 7.3.9, 7.2.22 and 7.1.32, addressing multiple security vulnerabilities. Depending on the type, occurrence, and usage of the affected codebase in a PHP application, successful exploitation of some of the most severe vulnerabilities could allow an attacker to execute arbitrary code in the context of the affected application with associated privileges. On the other hand, failed attempts at exploitation will likely result in a denial of service (DoS) condition on the affect
New Class of CPU Flaws Affect Almost Every Intel Processor Since 2011

New Class of CPU Flaws Affect Almost Every Intel Processor Since 2011

May 14, 2019
Academic researchers today disclosed details of the newest class of speculative execution side-channel vulnerabilities in Intel processors that impacts all modern chips, including the chips used in Apple devices. After the discovery of Spectre and Meltdown processor vulnerabilities earlier last year that put practically every computer in the world at risk, different classes of Spectre and Meltdown variations surfaced again and again. Now, a team of security researchers from multiple universities and security firms has discovered different but more dangerous speculative execution side-channel vulnerabilities in Intel CPUs. The newly discovered flaws could allow attackers to directly steal user-level, as well as system-level secrets from CPU buffers, including user keys, passwords, and disk encryption keys. Speculative execution is a core component of modern processors design that speculatively executes instructions based on assumptions that are considered likely to be true.

Hackers Found Exploiting Oracle WebLogic RCE Flaw to Spread Ransomware

May 01, 2019
Taking advantage of newly disclosed and even patched vulnerabilities has become common among cybercriminals, which makes it one of the primary attack vectors for everyday-threats, like crypto-mining, phishing, and ransomware. As suspected, a recently-disclosed critical vulnerability in the widely used Oracle WebLogic Server has now been spotted actively being exploited to distribute a never-before-seen ransomware variant, which researchers dubbed " Sodinokibi ." Last weekend, The Hacker News learned about a critical deserialization remote code execution vulnerability in Oracle WebLogic Server that could allow attackers to remotely run arbitrary commands on the affected servers just by sending a specially crafted HTTP request—without requiring any authorization. To address this vulnerability (CVE-2019-2725), which affected all versions of the Oracle WebLogic software and was given a severity score of 9.8 out of 10, Oracle rolled out an out-of-band security update on

Hackers Destroyed VFEmail Service – Deleted Its Entire Data and Backups

Feb 13, 2019
What could be more frightening than a service informing you that all your data is gone—every file and every backup servers are entirely wiped out? The worst nightmare of its kind. Right? But that's precisely what just happened this week with VFEmail.net, a US-based secure email provider that lost all data and backup files for its users after unknown hackers destroyed its entire U.S. infrastructure, wiping out almost two decades' worth of data and backups in a matter of few hours for no apparent reason. Started in 2001 by Rick Romero, VFEmail provides secure, private email services to companies and end users, both free and paid-for. Describing the attack as "catastrophic," the privacy-focused email service provider revealed that the attack took place on February 11 and that "all data" on their US servers—both the primary and the backup systems—has been completely wiped out, and it's seemingly beyond recovery. "Yes, @VFEmail is effectivel

16-Year-Old Boy Who Hacked Apple's Private Systems Gets No Jail Time

Sep 27, 2018
An Australian teenager who pleaded guilty to break into Apple's private systems  multiple times over several months and download some 90GB of secure files has avoided conviction and will not serve time in prison. An Australian Children's Court has given the now 19-year-old adult defendant, who was 16 at the time of committing the crime, a probation order of eight months, though the magistrate made him understand how serious his offense was. The teen, whose cannot be named under a local law that protects the identity of juveniles, told the court that he hacked into Apple's systems because he was a huge fan of the company and "dreamed of" working for the technology giant. The "Hacky Hack Hack" Folder The teen hacked into Apple's servers not once, but numerous times over the course of more than a year—between June 2015 and November 2016, and in April 2017. As soon as the tech giant detected his presence on their servers, it blocked him and

16-Year-Old Teen Hacked Apple Servers, Stole 90GB of Secure Files

Aug 17, 2018
Well, there's something quite embarrassing for Apple fans. Though Apple servers are widely believed to be unhackable, a 16-year-old high school student proved that nothing is impossible. The teenager from Melbourne, Australia, managed to break into Apple servers and downloaded some 90GB of secure files, including extremely secure authorized keys used to grant login access to users, as well as access multiple user accounts. The teen told the authorities that he hacked Apple because he was a huge fan of the company and "dreamed of" working for the technology giant. What's more embarrassing? The teen, whose name is being withheld as he's still a minor, hacked the company's servers not once, but numerous times over the course of more than a year, and Apple's system administrators failed to stop their users' data from being stolen. When Apple finally noticed the intrusion, the company contacted the FBI, which took the help of the Australian Fede
Over 70,000 Memcached Servers Still Vulnerable to Remote Hacking

Over 70,000 Memcached Servers Still Vulnerable to Remote Hacking

Jul 18, 2017
Nothing in this world is fully secure, from our borders to cyberspace. I know vulnerabilities are bad, but the worst part comes in when people just don't care to apply patches on time. Late last year, Cisco's Talos intelligence and research group discovered three critical remote code execution (RCE) vulnerabilities in Memcached that exposed major websites including Facebook, Twitter, YouTube, Reddit, to hackers. Memcached is a popular open-source and easily deployable distributed caching system that allows objects to be stored in memory. The Memcached application has been designed to speed up dynamic web applications ( for example php-based websites) by reducing stress on the database that helps administrators to increase performance and scale web applications. It's been almost eight months since the Memcached developers have released patches for three critical RCE vulnerabilities (CVE-2016-8704, CVE-2016-8705 and CVE-2016-8706) but tens of thousands of servers

Unpatched Wordpress Flaw Could Allow Hackers To Reset Admin Password

May 04, 2017
WordPress, the most popular CMS in the world, is vulnerable to a logical vulnerability that could allow a remote attacker to reset targeted users' password under certain circumstances. The vulnerability (CVE-2017-8295) becomes even more dangerous after knowing that it affects all versions of WordPress — including the latest 4.7.4 version. The WordPress flaw was discovered by Polish security researcher Dawid Golunski of Legal Hackers last year in July and reported it to the WordPress security team, who decided to ignore this issue, leaving millions of websites vulnerable. "This issue has been reported to WordPress security team multiple times with the first report sent back in July 2016. It was reported both directly via security contact email, as well as via HackerOne website," Golunski wrote in an advisory published today. "As there has been no progress, in this case, this advisory is finally released to the public without an official patch." Golunski
