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 ga...

An enterprise-grade surveillanceware dubbed Hermit has been put to use by entities operating from within Kazakhstan, Syria, and Italy over the years since 2019, new research has revealed. Lookout attributed the spy software, which is equipped to target both Android and iOS, to an Italian company named RCS Lab S.p.A and Tykelab Srl, a telecom services provider which it suspects to be a front company. The San Francisco-based cybersecurity firm said it detected the campaign aimed at Kazakhstan in April 2022. Hermit is modular and comes with myriad capabilities that allow it to "exploit a rooted device, record audio and make and redirect phone calls, as well as collect data such as call logs, contacts, photos, device location and SMS messages," Lookout researchers Justin Albrecht and Paul Shunk  said  in a new write-up. The spyware is believed to be distributed via SMS messages that trick users into installing what are seemingly innocuous apps from Samsung, Vivo, and Oppo, w...

It was first the pandemic that changed the usual state of work - before, it was commuting, working in the office & coming home for most corporate employees. Then, when we had to adapt to the self-isolation rules, the work moved to home offices, which completely changed the workflow for many businesses. As the pandemic went down, we realized success never relied on where the work was done. Whether your office is your kitchen, your bedroom, a nearby cafe, or your actual workplace in an office building, it all comes down to the fact that job success has nothing to do with your location.  The role of the office in the hybrid era is also changing - according to the research conducted by  PwC , it now serves the purpose of collaborating with team members and building relationships. From an employee's side, it sounds pretty logical and obvious.  However, if we look at hybrid work with the eyes of an employer, things get complicated. How does one make sure corporate device...

A sophisticated Chinese advanced persistent threat (APT) actor exploited a critical security vulnerability in Sophos' firewall product that came to light earlier this year to infiltrate an unnamed South Asian target as part of a highly-targeted attack. "The attacker implement[ed] an interesting web shell backdoor, create[d] a secondary form of persistence, and ultimately launch[ed] attacks against the customer's staff," Volexity  said  in a report. "These attacks aimed to further breach cloud-hosted web servers hosting the organization's public-facing websites." The zero-day flaw in question is tracked as  CVE-2022-1040  (CVSS score: 9.8), and concerns an authentication bypass vulnerability that can be weaponized to execute arbitrary code remotely. It affects Sophos Firewall versions 18.5 MR3 (18.5.3) and earlier. The cybersecurity firm, which issued a patch for the flaw on March 25, 2022, noted that it was abused to "target a small set of spec...

WordPress websites using a widely used plugin named Ninja Forms have been updated automatically to remediate a critical security vulnerability that's suspected of having been actively exploited in the wild. The issue, which relates to a case of code injection, is rated 9.8 out of 10 for severity and affects multiple versions starting from 3.0. It has been fixed in 3.0.34.2, 3.1.10, 3.2.28, 3.3.21.4, 3.4.34.2, 3.5.8.4, and 3.6.11. Ninja Forms is a  customizable contact form builder  that has over 1 million installations. According to Wordfence, the bug "made it possible for unauthenticated attackers to call a limited number of methods in various Ninja Forms classes, including a method that unserialized user-supplied content, resulting in Object Injection." "This could allow attackers to execute arbitrary code or delete arbitrary files on sites where a separate [property oriented programming] chain was present," Chloe Chamberland of Wordfence  noted . Suc...

Microsoft is warning that the BlackCat ransomware crew is leveraging exploits for  unpatched Exchange server  vulnerabilities to gain access to targeted networks. Upon gaining an entry point, the attackers swiftly moved to gather information about the compromised machines, followed by carrying out credential theft and lateral movement activities, before harvesting intellectual property and dropping the ransomware payload. The entire sequence of events played out over the course of two full weeks, the Microsoft 365 Defender Threat Intelligence Team  said  in a report published this week. "In another incident we observed, we found that a ransomware affiliate gained initial access to the environment via an internet-facing Remote Desktop server using compromised credentials to sign in," the researchers said, pointing out how "no two BlackCat 'lives' or deployments might look the same." BlackCat , also known by the names ALPHV and Noberus, is a relatively n...

A "dangerous piece of functionality" has been discovered in Microsoft 365 suite that could be potentially abused by a malicious actor to mount attacks on cloud infrastructure and ransom files stored on SharePoint and OneDrive. The cloud ransomware attack makes it possible to launch file-encrypting malware to "encrypt files stored on SharePoint and OneDrive in a way that makes them unrecoverable without dedicated backups or a decryption key from the attacker," Proofpoint  said  in a report published today. The infection sequence can be carried out using a combination of Microsoft APIs, command-line interface (CLI) scripts, and PowerShell scripts, the enterprise security firm added. The attack, at its core, hinges on a Microsoft 365 feature called AutoSave that creates copies of older file versions as and when users make edits to a file stored on OneDrive or SharePoint Online. It commences with gaining unauthorized access to a target user's SharePoint Online...
