A SaaS Security Challenge: Getting Permissions All in One Place 

A SaaS Security Challenge: Getting Permissions All in One Place
May 08, 2024Attack Surface / SaaS Security
Permissions in SaaS platforms like Salesforce, Workday, and Microsoft 365 are remarkably precise. They spell out exactly which users have access to which data sets. The terminology differs between apps, but each user's base permission is determined by their role, while additional permissions may be granted based on tasks or projects they are involved with. Layered on top of that are custom permissions required by an individual user.  For example, look at a sales rep who is involved in a tiger team investigating churn while also training two new employees. The sales rep's role would grant her one set of permissions to access prospect data, while the tiger team project would grant access to existing customer data. Meanwhile, special permissions are set up, providing the sales rep with visibility into the accounts of the two new employees. While these permissions are precise, however, they are also very complex. Application admins don't have a single screen within these applications th

Critical Patches Released for New Flaws in Cisco, Fortinet, VMware Products
Feb 08, 2024 Cyber Threat / Network Security
Cisco, Fortinet, and VMware have released security fixes for multiple security vulnerabilities, including critical weaknesses that could be exploited to perform arbitrary actions on affected devices. The first set from Cisco consists of three flaws – CVE-2024-20252 and CVE-2024-20254 (CVSS score: 9.6) and CVE-2024-20255 (CVSS score: 8.2) – impacting Cisco Expressway Series that could allow an unauthenticated, remote attacker to conduct cross-site request forgery (CSRF) attacks. All the issues, which were found during internal security testing, stem from insufficient CSRF protections for the web-based management interface that could permit an attacker to perform arbitrary actions with the privilege level of the affected user. "If the affected user has administrative privileges, these actions could include modifying the system configuration and creating new privileged accounts," Cisco  said  about CVE-2024-20252 and CVE-2024-20254. On the other hand, successful exploitatio

AnyDesk Hacked: Popular Remote Desktop Software Mandates Password Reset

AnyDesk Hacked: Popular Remote Desktop Software Mandates Password Reset
Feb 03, 2024 Cyber Attack / Software Security
Remote desktop software maker AnyDesk disclosed on Friday that it suffered a cyber attack that led to a compromise of its production systems. The German company said the incident, which it discovered following a security audit, is not a ransomware attack and that it has notified relevant authorities. "We have revoked all security-related certificates and systems have been remediated or replaced where necessary," the company  said  in a statement. "We will be revoking the previous code signing certificate for our binaries shortly and have already started replacing it with a new one." Out of an abundance of caution, AnyDesk has also revoked all passwords to its web portal, my.anydesk[.]com, and it's urging users to change their passwords if the same passwords have been reused on other online services. It's also recommending that users download the latest version of the software, which comes with a new  code signing certificate . AnyDesk did not disclose

AllaKore RAT Malware Targeting Mexican Firms with Financial Fraud Tricks

AllaKore RAT Malware Targeting Mexican Firms with Financial Fraud Tricks
Jan 27, 2024 Malware / Software Update
Mexican financial institutions are under the radar of a new spear-phishing campaign that delivers a modified version of an open-source remote access trojan called  AllaKore RAT . The BlackBerry Research and Intelligence Team attributed the activity to an unknown Latin America-based financially motivated threat actor. The campaign has been active since at least 2021. "Lures use Mexican Social Security Institute (IMSS) naming schemas and links to legitimate, benign documents during the installation process," the Canadian company  said  in an analysis published earlier this week. "The AllaKore RAT payload is heavily modified to allow the threat actors to send stolen banking credentials and unique authentication information back to a command-and-control (C2) server for the purposes of financial fraud." The attacks appear to be designed to particularly single out large companies with gross revenues over $100 million. Targeted entities span retail, agriculture, publ

Jan 09, 2024 Network Security / Data Protection
A security flaw has been disclosed in Kyocera's  Device Manager  product that could be exploited by bad actors to carry out malicious activities on affected systems. "This vulnerability allows attackers to coerce authentication attempts to their own resources, such as a malicious SMB share, to capture or relay Active Directory hashed credentials if the 'Restrict NTLM: Outgoing NTLM traffic to remote servers' security policy is not enabled," Trustwave  said . Tracked as  CVE-2023-50916 , Kyocera, in an  advisory  released late last month, described it as a path traversal issue that enables an attacker to intercept and alter a local path pointing to the backup location of the database to a universal naming convention (UNC) path. This, in turn, causes the web application to attempt to authenticate the rogue UNC path, resulting in unauthorized access to clients' accounts and data theft. Furthermore, depending on the configuration of the environment, it could be exploited to
