Cisco investigates breach after stolen data for sale on hacking forum

-

 


Cisco has confirmed to BleepingComputer that it is investigating recent claims that it suffered a breach after a threat actor began selling allegedly stolen data on a hacking forum.

"Cisco is aware of reports that an actor is alleging to have gained access to certain Cisco-related files," a Cisco spokesperson told BleepingComputer.

"We have launched an investigation to assess this claim, and our investigation is ongoing."

This statement comes after a well-known threat actor named "IntelBroker" said that he and two others called "EnergyWeaponUser and "zjj" breached Cisco on October 6, 2024, and stole a large amount of developer data from the company.

"Compromised data: Github projects, Gitlab Projects, SonarQube projects, Source code, hard coded credentials, Certificates, Customer SRCs, Cisco Confidential Documents, Jira tickets, API tokens, AWS Private buckets, Cisco Technology SRCs, Docker Builds, Azure Storage buckets, Private & Public keys, SSL Certificates, Cisco Premium Products & More!," reads the post to a hacking forum.


IntelBroker also shared samples of the alleged stolen data, including a database, customer information, various customer documentation, and screenshots of customer management portals.

However, the threat actor did not provide further details about how the data was obtained.

In June, IntelBroker began selling or leaking data from numerous companies, including T-Mobile, AMD, and Apple. Sources familiar with the attack told BleepingComputer it was stolen from a third-party managed services provider for DevOps and software development.

It is unknown if the Cisco breach is related to these June breaches.

BleepingComputer again contacted this third-party vendor to confirm if they suffered a cyberattack but has not received a reply.

Update 10/16/24: Cisco says that they are continuing to investigate the reports but have found no evidence their systems were breached.

"Cisco is investigating reports that an unauthorized actor is alleging to have gained access to certain Cisco data and data of our customers," Cisco told BleepingComputer.

"Cisco takes this allegation seriously and we have engaged law enforcement as part of this investigation."

"To date, our investigation has found no evidence of our systems being impacted. We will notify customers where we confirm that the actor has obtained their confidential information."

  The European Union Agency for Cybersecurity (ENISA) has signed a Working Arrangement with the Cybersecurity and Infrastructure Security Agency (CISA) of the US, in the areas of capacity-building, best practices exchange and boosting situational awareness. Geopolitics have shaped the cyber threat landscape, bringing like-minded partners closer together in the wake of common cyber challenges and advances in digital technologies. Today at the EU-US Cyber Dialogue, ENISA and CISA announced the signing of their Working Arrangement as an important milestone in the overall cooperation between the United States and the European Union in the field of cybersecurity, also following the Joint Statement of European Commissioner Thierry Breton and U.S. Secretary for Homeland Security Alejandro Mayorkas of January 2023. ENISA’s International Strategy directs the Agency to be selective in engaging with international partners and to limit its overall approach in international cooperation to those...

In January 2024, cybersecurity faced a remarkable surge in threats, with a focus on exploiting vulnerabilities in technologies from leading vendors. This spike in cyber attacks highlighted the urgent necessity for robust security posture and swift responses to mitigate these vulnerabilities.  Below is an in-depth analysis of the most critical vulnerabilities targeted during January. CVE-2023-46805 and CVE-2024-21887:   CISA Warns Against Ivanti Zero-Day Vulnerabilities On January 19, 2024, the Cybersecurity and Infrastructure Security Agency (CISA) issued an alert regarding two critical zero-day vulnerabilities discovered in Ivanti products:  CVE-2023-46805 and  CVE-2024-21887.  Assigned CVSS scores of 8.2 (High) and 9.1 (Critical), these vulnerabilities underscore a significant risk to cybersecurity, marked by their capability for arbitrary command execution. This prompted an emergency directive for immediate mitigation within federal agencies, highlighting the...

SmartScreen Vulnerability: CVE-2024-21412 Facts and Fixes

-
Image
On Feb. 13, 2024, Microsoft issued a  patch  for CVE-2024-21412, a  Microsoft Defender SmartScreen  vulnerability revolving around internet shortcuts. Previously, we discovered that an advanced persistent threat (APT) group we track under the name Water Hydra has been exploiting CVE-2024-21412 in a sophisticated campaign targeting financial market traders, allowing the group to bypass Microsoft Defender SmartScreen and infect its victims with the DarkMe remote access trojan (RAT). Threat actors are constantly finding new ways of identifying and exploiting gaps to bypass security measures. We found that the bypass of CVE-2023-36025 (a previously patched SmartScreen vulnerability) led to the discovery and exploitation of CVE-2024-21412. This highlights how threat actors can circumvent patches by identifying new vectors of attack around a patched software component. It is important that organizations are able to identify and mitigate vulnerabilities, especiall...
