krb5: Kerberos RC4-HMAC-MD5 Checksum Vulnerability Enabling Message Spoofing via MD5 Collisions

A vulnerability in the MIT Kerberos implementation allows GSSAPI-protected messages using RC4-HMAC-MD5 to be spoofed due to weaknesses in the MD5 checksum design. If RC4 is preferred over stronger encryption types, an attacker could exploit MD5 collisions to forge message integrity codes. This ma...

CVE-2018-17177

An issue was discovered on Neato Botvac Connected 2.2.0 and Botvac 85 1.2.1 devices. Static encryption is used for the copying of so-called "black box" logs event logs and core dumps to a USB stick. These logs are RC4-encrypted with a 9-character password of ^JEd4W!I that is obfuscated by hiding ...

CVE-2017-15997

In the "NQ Contacts Backup & Restore" application 1.1 for Android, RC4 encryption is used to secure the user password locally stored in shared preferences. Because there is a static RC4 key, an attacker can gain access to user credentials more easily by leveraging access to the preferences XML fi...

Since the Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability was disclosed by Microsoft on Nov 8 2022 and per RFC8429 it is assumed that rc4-hmac is weak, Vulnerable Samba Active Directory DCs will issue rc4-hmac encrypted tickets despite the target server supporting better encryption...

Raspberry Robin Worm Evolves to Attack Financial and Insurance Sectors in Europe

Financial and insurance sectors in Europe have been targeted by the Raspberry Robin worm, as the malware continues to evolve its post-exploitation capabilities while remaining under the radar. "What is unique about the malware is that it is heavily obfuscated and highly complex to statically...

The vulnerability of the Kerberos protocol for Windows operating systems allows attackers to increase their privileges.

The vulnerability of the Kerberos protocol for Windows operating systems lies in the use of the cryptographic algorithm RC4-HMAC, which has vulnerabilities. Exploiting this vulnerability can allow a malicious actor to enhance their privileges remotely...

RC4 Is Still Considered Harmful

By James Forshaw, Project Zero I've been spending a lot of time researching Windows authentication implementations, specifically Kerberos. In June 2022 I found an interesting issue number 2310 with the handling of RC4 encryption that allowed you to authenticate as another user if you could either...
