Vulnerabilities

Digital Oscilloscope comes with backdoor accounts and old software components

  • Oscilloscopes are devices used in laboratories to measure how an electrical signal changes over time by showing waveform representation. Researchers at SEC-Consult found that the SDS 1202X-E Digital Oscilloscope from Siglent lacks authentication for access via the EasyScopeX software, which allows users to retrieve and manipulate waveform data to isolate signals.
  • The SDS 1202X-E Digital Oscilloscope also had two hardcoded backdoor accounts, ‘root’ and ‘siglent’. The two accounts were found in the ‘/etcshadow’ directory by connecting to the oscilloscope via the UART interface.
  • The device has Telnet service turned on, which listens on the default TCP port. If an attacker was connected to the oscilloscope this way then they would be granted rooted access on the local network.

SplitSpectre differs by being easier to execute as it ‘requires a smaller piece of vulnerable code available in the victim’s attack surface’.
  • The research team performed successful attacks using SplitSpectre against Intel Haswell and Skylake CPUs, and AMD Ryzen processors via SpiderMonkey 52.7.4

$100 billion company ran NotPetya like EternalGlue on its network

  • The company exposed it’s IT environment to a worm, dubbed EternalGlue, that operates in a similar way to NotPetya. EternalGlue was created by researchers at NCCGroup and includes the capability to deploy the open source credential stealing tool Mimikatz.
  • Due to the testing environment, EternalGlue also includes telemetry and safeguards so that no lasting Qudamage was inflicted on the infected system. During the first run of the malware, three unpatched machines were discovered and attacked, from which kernel level access was obtained and the network was infected.
  • The test revealed that setting ‘Account is sensitive and cannot be delegated’ stops an account’s credentials from being forwarded to other computers on a network via a trusted application. This limits the scope of attacks that use elevation of privilege activities and in the case of this test, it was discovered that this setting was effective at blocking the spread of EternalGlue across the network.
