Atlassian has released software fixes to address  four critical flaws  in its software that, if successfully exploited, could result in remote code execution. The list of vulnerabilities is below - CVE-2022-1471  (CVSS score: 9.8) - Deserialization vulnerability in  SnakeYAML library  that can lead to remote code execution in multiple products CVE-2023-22522  (CVSS score: 9.0) - Remote code execution vulnerability in Confluence Data Center and Confluence Server (affects all versions including and after 4.0.0) CVE-2023-22523  (CVSS score: 9.8) - Remote code execution vulnerability in Assets Discovery for Jira Service Management Cloud, Server, and Data Center (affects all versions up to but not including 3.2.0-cloud / 6.2.0 data center and server) CVE-2023-22524  (CVSS score: 9.6) - Remote code execution vulnerability in Atlassian Companion app for macOS (affects all versions up to but not including 2.0.0) Atlassian described CVE-2023-22522...

Chipmaker Qualcomm has released more information about three high-severity security flaws that it said came under "limited, targeted exploitation" back in October 2023. The  vulnerabilities  are as follows - CVE-2023-33063  (CVSS score: 7.8) - Memory corruption in DSP Services during a remote call from HLOS to DSP. CVE-2023-33106  (CVSS score: 8.4) - Memory corruption in Graphics while submitting a large list of sync points in an AUX command to the IOCTL_KGSL_GPU_AUX_COMMAND. CVE-2023-33107  (CVSS score: 8.4) - Memory corruption in Graphics Linux while assigning shared virtual memory region during IOCTL call. Google's Threat Analysis Group and Google Project Zero  revealed  back in October 2023 that the three flaws, along with  CVE-2022-22071  (CVSS score: 8.4), have been exploited in the wild as part of limited, targeted attacks. A security researcher named luckyrb, the Google Android Security team, and TAG researcher Benoît Sevens...

The Russia-linked influence operation called Doppelganger has targeted Ukrainian, U.S., and German audiences through a combination of inauthentic news sites and social media accounts. These campaigns are designed to amplify content designed to undermine Ukraine as well as propagate anti-LGBTQ+ sentiment, U.S. military competence, and Germany's economic and social issues, according to a new Recorded Future report shared with The Hacker News. Doppelganger ,  described  by Meta as the "largest and the most aggressively-persistent Russian-origin operation," is a  pro-Russian network  known for spreading anti-Ukrainian propaganda. Active since at least February 2022, it has been linked to two companies named Structura National Technologies and Social Design Agency. Activities associated with the influence operation are known to leverage manufactured websites as well as those impersonating authentic media – a technique called brandjacking – to disseminate adversarial n...

A new "post-exploitation tampering technique" can be abused by malicious actors to visually deceive a target into believing that their Apple iPhone is running in Lockdown Mode when it's actually not and carry out covert attacks. The novel method, detailed by Jamf Threat Labs in a  report  shared with The Hacker News, "shows that if a hacker has already infiltrated your device, they can cause Lockdown Mode to be 'bypassed' when you trigger its activation." In other words, the goal is to implement Fake Lockdown Mode on a device that's compromised by an attacker through other means, such as  unpatched security flaws  that can trigger execution of arbitrary code. Lockdown Mode , introduced by Apple last year with iOS 16, is an  enhanced security measure  that aims to safeguard high-risk individuals from sophisticated digital threats such as mercenary spyware by  minimizing the attack surface . What it doesn't do is prevent the execution of mali...

Microsoft Copilot has been called one of the most powerful productivity tools on the planet. Copilot is an AI assistant that lives inside each of your Microsoft 365 apps — Word, Excel, PowerPoint, Teams, Outlook, and so on. Microsoft's dream is to take the drudgery out of daily work and let humans focus on being creative problem-solvers. What makes Copilot a different beast than ChatGPT and other AI tools is that it has access to everything you've ever worked on in 365. Copilot can instantly search and compile data from across your documents, presentations, email, calendar, notes, and contacts. And therein lies the problem for information security teams. Copilot can access all the sensitive data that a user can access, which is often far too much. On average, 10% of a company's M365 data is open to all employees. Copilot can also rapidly generate  net new  sensitive data that must be protected. Prior to the AI revolution, humans' ability to create and share data ...

New research has found that over 15,000 Go module repositories on GitHub are vulnerable to an attack called repojacking. "More than 9,000 repositories are vulnerable to repojacking due to GitHub username changes," Jacob Baines, chief technology officer at VulnCheck,  said  in a report shared with The Hacker News. "More than 6,000 repositories were vulnerable to repojacking due to account deletion." Collectively, these repositories account for no less than 800,000 Go module-versions. Repojacking , a portmanteau of "repository" and "hijacking," is an attack technique that allows a bad actor to take advantage of account username changes and deletions to create a repository with the same name and the pre-existing username to stage open-source software supply chain attacks. Earlier this June, cloud security firm Aqua  revealed  that millions of software repositories on GitHub are likely vulnerable to the threat, urging organizations that undergo...

A previously undocumented threat actor has been linked to a cyber attack targeting an aerospace organization in the U.S. as part of what's suspected to be a cyber espionage mission. The BlackBerry Threat Research and Intelligence team is tracking the activity cluster as  AeroBlade . Its origin is currently unknown and it's not clear if the attack was successful. "The actor used spear-phishing as a delivery mechanism: A weaponized document, sent as an email attachment, contains an embedded remote template injection technique and a malicious VBA macro code, to deliver the next stage to the final payload execution," the company  said  in an analysis published last week. The network infrastructure used for the attack is said to have gone live around September 2022, with the offensive phase of the intrusion occurring nearly a year later in July 2023, but not before the adversary took steps to improvise its toolset to make it more stealthy in the intervening time perio...

Microsoft on Monday said it detected Kremlin-backed nation-state activity exploiting a now-patched critical security flaw in its Outlook email service to gain unauthorized access to victims' accounts within Exchange servers. The tech giant  attributed  the intrusions to a threat actor it called  Forest Blizzard  (formerly Strontium), which is also widely tracked under the monikers APT28, BlueDelta, Fancy Bear, FROZENLAKE, Iron Twilight, Sednit, Sofacy, and TA422. The security vulnerability in question is  CVE-2023-23397  (CVSS score: 9.8), a critical privilege escalation bug that could allow an adversary to access a user's Net-NTLMv2 hash that could then be used to conduct a relay attack against another service to authenticate as the user. It was patched by Microsoft in March 2023. The goal, according to the Polish Cyber Command (DKWOC), is to obtain unauthorized access to mailboxes belonging to public and private entities in the country. "In the next...

New research has unearthed multiple novel attacks that break Bluetooth Classic's forward secrecy and future secrecy guarantees, resulting in adversary-in-the-middle (AitM) scenarios between two already connected peers. The issues, collectively named  BLUFFS , impact Bluetooth Core Specification 4.2 through 5.4. They are tracked under the identifier  CVE-2023-24023  (CVSS score: 6.8) and were responsibly disclosed in October 2022. The attacks "enable device impersonation and machine-in-the-middle across sessions by only compromising one session key," EURECOM researcher Daniele Antonioli said in a study published late last month. This is made possible by leveraging two new flaws in the Bluetooth standard's session key derivation mechanism that allow the derivation of the same key across sessions. While forward secrecy in key-agreement cryptographic protocols ensures that past communications are not revealed, even if the private keys to a particular exchange are re...
