Cisco Talos examined several frequently used code repositories. We looked specifically at the security afforded to developer accounts, and how difficult it would be for an attacker to take over a developer account.

Cisco Talos examined several frequently used code repositories. We looked specifically at the security afforded to developer accounts, and how difficult it would be for an attacker to take over a developer account.

By Jaeson Schultz. Over the past several years, high-profile software supply chain attacks have increased in frequency. These attacks can be difficult to detect and source code repositories became a key focus of this research. Developer account takeovers present a substantial risk to the software supply chain because attackers who successfully compromise a developer account could conceal malicious code in software packages used by others. Talos analyzed several of the major software repositories to assess the level of developer account security, focusing specifically on whether developer accounts could be recovered by re-registering expired domain names and triggering password resets. Many software repositories have already begun taking steps to enhance the security of developer accounts. Talos has identified additional areas where the security of developer accounts could be improved. Talos worked with vulnerable repositories to resolve issues that we found. Software supply chain att...

From the World Cup in Qatar to robotics manufacturing in east Asia, this incident responder combines experience from multiple arenas  By Jon Munshaw.  Yuri “Jerzy” Kramarz helped secure everything from the businesses supporting the upcoming World Cup in Qatar to the Black Hat security conference and critical national infrastructure.  He’s no stranger to cybersecurity on the big stage, but he still enjoys working with companies and organizations of all sizes in all parts of the world.  “What really excites me is making companies more secure,” he said in a recent interview. “That comes down to a couple things, but it’s really about putting a few solutions together at first and then hearing the customer’s feedback and building from there.”  Yuri is a senior incident response consultant with Cisco Talos Incident Response (CTIR) currently based in Qatar. He walks customers through various exercises, incident response plan creation, recovery in the event of a cyber attack and much more unde...

“You have completely different angles in preparing different customers for defense during major global events depending on their role, technology and function,” Kramarz said.

Cisco Talos has released new coverage to detect and prevent the exploitation of two recently disclosed vulnerabilities collectively referred to as "ProxyNotShell," affecting Microsoft Exchange Servers 2013, 2016 and 2019. One of these vulnerabilities could allow an attacker to execute remote code on the targeted server. Limited exploitation of these vulnerabilities in the wild has been reported. CVE-2022-41040 is a Server Side Request Forgery (SSRF) vulnerability, while CVE-2022-41082 enables Remote Code Execution (RCE) when PowerShell is accessible to the attackers. While no fixes or patches are available yet, Microsoft has provided mitigations for on-premises Microsoft Exchange users on Sept. 29, 2022. Even organizations that use Exchange Online may still be affected if they run a hybrid server. Cisco Talos is closely monitoring the recent reports of exploitation attempts against these vulnerabilities and strongly recommends users implement mitigation steps while waiting for securit...

A vulnerability in the self-healing functionality of Cisco IOS XE Software for Embedded Wireless Controllers on Catalyst Access Points could allow an authenticated, local attacker to escape the restricted controller shell and execute arbitrary commands on the underlying operating system of the access point. This vulnerability is due to improper checks throughout the restart of certain system processes. An attacker could exploit this vulnerability by logging on to an affected device and executing certain CLI commands. A successful exploit could allow the attacker to execute arbitrary commands on the underlying OS as root. To successfully exploit this vulnerability, an attacker would need valid credentials for a privilege level 15 user of the wireless controller.
