The Five Eyes (FVEY) intelligence alliance has issued a new cybersecurity advisory warning of cyber threat actors exploiting known security flaws in Ivanti Connect Secure and Ivanti Policy Secure gateways, noting that the Integrity Checker Tool (ICT) can be deceived to provide a false sense of security. "Ivanti ICT is not sufficient to detect compromise and that a cyber threat actor may be able to gain root-level persistence despite issuing factory resets," the agencies  said . To date, Ivanti has disclosed five security vulnerabilities impacting its products since January 10, 2024, out of which four have come under active exploitation by multiple threat actors to deploy malware - CVE-2023-46805  (CVSS score: 8.2) - Authentication bypass vulnerability in web component CVE-2024-21887  (CVSS score: 9.1) - Command injection vulnerability in web component CVE-2024-21888  (CVSS score: 8.8) - Privilege escalation vulnerability in web component CVE-2024-21893  ...

GitHub on Thursday announced that it’s enabling secret scanning push protection by default for all pushes to public repositories. “This means that when a supported secret is detected in any push to a public repository, you will have the option to remove the secret from your commits or, if you deem the secret safe, bypass the block,” Eric Tooley and Courtney Claessens  said . Push protection  was  first piloted  as an opt-in feature in August 2023, although it has been under testing since April 2022. It became  generally available  in May 2023. The  secret scanning  feature is designed to identify over  200 token types  and patterns from more than 180 service providers in order to prevent their fraudulent use by malicious actors.  The development comes nearly five months after the Microsoft subsidiary  expanded  secret scanning to include validity checks for popular services such as Amazon Web Services (AWS), Microsof...

Cybersecurity researchers have disclosed a new attack technique called  Silver SAML  that can be successful even in cases where mitigations have been applied against Golden SAML attacks. Silver SAML “enables the exploitation of SAML to launch attacks from an identity provider like Entra ID against applications configured to use it for authentication, such as Salesforce,” Semperis researchers Tomer Nahum and Eric Woodruff  said  in a report shared with The Hacker News. Golden SAML (short for  Security Assertion Markup Language ) was  first documented  by CyberArk in 2017. The attack vector, in a nutshell, entails the abuse of the interoperable authentication standard to impersonate almost any identity in an organization. It’s also similar to the  Golden Ticket attack  in that it grants attackers the ability to gain unauthorized access to any service in a federation with any privileges and to stay persistent in this environment in a stealth...

Threat hunters have discovered a new Linux malware called  GTPDOOR  that’s designed to be deployed in telecom networks that are adjacent to GPRS roaming exchanges ( GRX ) The  malware  is novel in the fact that it leverages the GPRS Tunnelling Protocol ( GTP ) for command-and-control (C2) communications. GPRS roaming allows subscribers to access their GPRS services while they are beyond the reach of their home mobile network. This is facilitated by means of a GRX that transports the roaming traffic using GTP between the visited and the home Public Land Mobile Network ( PLMN ). Security researcher haxrob, who discovered two  GTPDOOR   artifacts  uploaded to VirusTotal from China and Italy, said the backdoor is likely linked to a known threat actor tracked as  LightBasin  (aka UNC1945), which was previously disclosed by CrowdStrike in October 2021 in connection with a series of attacks targeting the telecom sector to steal subscriber infor...

The notorious Lazarus Group actors exploited a recently patched privilege escalation flaw in the Windows Kernel as a zero-day to obtain kernel-level access and disable security software on compromised hosts. The vulnerability in question is  CVE-2024-21338  (CVSS score: 7.8), which can permit an attacker to gain SYSTEM privileges. It was resolved by Microsoft earlier this month as part of  Patch Tuesday updates . "To exploit this vulnerability, an attacker would first have to log on to the system," Microsoft  said . "An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system." While there were no indications of active exploitation of CVE-2024-21338 at the time of the release of the updates, Redmond on Wednesday revised its "Exploitability assessment" for the flaw to "Exploitation Detected."  It’s currently not clear when the attacks took place, but the vulnerability...
