∗∗∗ Colibri Loaders Unique Persistence Technique Using Get-Variable Cmdlet ∗∗∗
---------------------------------------------
Recently there has been a lot of talk on Twitter regarding the Colibri Loader and its persistence mechanism, which somehow uses the Powershell's Get-Variable cmdlet. According to MSDN, Get-Variable is a Powershell cmdlet that gets the PowerShell variables in the current console.
In short, on Windows 10 or later systems, Colibri Loader drops its copy in %APPDATA%\Local\Microsoft\WindowsApps directory with the name Get-Variable.exe. It then creates a scheduled task to run Powershell in a hidden manner using powershell.exe -windowstyle hidden
To the naked eye, it looks that only Powershell is running, but this scheduled task somehow triggers Colibri Loader to run.

Ransomware groups in recent years have ramped up the threats against victims to incentivize them to pay the ransom in return for their stolen and encrypted data. But a new crew is essentially destroying files larger than 2MB, so data in those files is lost even if the ransom is paid.

Despite open source software’s essential role in all software built today, it’s far too easy for bad actors to circulate malicious packages that attack the systems and users running that software. Unlike mobile app stores that can scan for and reject malicious contributions, package repositories have limited resources to review the thousands of daily updates and must maintain an open model where anyone can freely contribute.

After Microsoft patched and went public with CVE-2022-26809, the recent RPC vulnerability, we set up a complete Windows 10 system exposing port 445/TCP "to the world." The system is not patched for the RPC vulnerability. And to keep things more interesting, we are forwarding traffic from a subset of our honeypots to the system. This gives us a pretty nice cross-section and keeps the system pretty busy. Other than not applying the April patches, the system isn't particularly vulnerable and is left in the default configuration (firewall disabled, of course).

∗∗∗ OpenSSL Infinite loop when parsing certificates CVE-2022-0778 ∗∗∗
---------------------------------------------
A vulnerability CVE-2022-0778 was found in OpenSSL that allows to trigger an infinite loop by crafting a certificate that has invalid elliptic curve parameters. Since certificate parsing happens before verification of the certificate signature, any process that parses an externally supplied certificate leads to a DoS (Denial of service) attack. SonicWall is investigating its product line to determine which products and cloud services may be affected by this vulnerability.
