Microsoft makes CodeQL queries public so security pros can better understand SolarWinds attack

Microsoft has gained praise from security researchers by making its CodeQL queries community so any firm could use the open up supply equipment to assess if they seasoned any vulnerabilities from the SolarWinds hack or related offer chain attacks.

CodeQL queries code as if it ended up info, which allows developers publish a question that finds all the variants of a vulnerability, and then share it with some others.

In a site write-up Thursday that facts how it utilised the CodeQL approach, Microsoft referred to the SolarWinds attack as Solorigate. In this scenario, the attacker bought into the distant management software servers of several corporations and injected a backdoor into the SolarWinds Orion software program update. The attacker modified the binaries in Orion and distributed them by means of earlier reputable update channels. This enable the attacker remotely accomplish malicious functions, this sort of as credential theft, privilege escalation, and lateral movement to steal sensitive facts.

Microsoft explained the SolarWinds incident has reminded organizations to reflect not just on their readiness to answer to innovative attacks, but also the resilience of its have codebases. In the site, Microsoft points out its use of CodeQL queries to examine its resource code at scale and rule out the existence of the code-amount indicators of compromise (IoCs) and coding designs affiliated with Solorigate.

“Note that the queries we go over in this blog site simply just provide to property in on source code that shares similarities with the resource in the Solorigate implant, either in the syntactic features (names, literals) or in features,” the web site explained. “Both can take place coincidentally in benign code, so all results will require assessment to determine if they are actionable. Furthermore, there’s no promise that the malicious actor is constrained to the exact operation or coding fashion in other operations, so these queries might not detect other implants that deviate substantially from the ways noticed in the Solorigate implant.”

Microsoft underscored that security scientists ought to only look at what they outlined in the site as just a element in a mosaic of techniques to audit for compromise.

Security researchers have been quite delighted to master of Microsoft’s conclusion to share its CodeQL queries.

Andrew Barratt, handling principal of remedies and investigations at Coalfire, explained although Microsoft pretty generally gets criticized by areas of the security group, the program maker has shared a further beneficial set of instruments and strategies that incident responders and blue teamers can leverage to even further automate their efforts. Barratt additional that analyzing the SolarWinds compromise, or even just ‘potential’ compromise activity has been a massive aspect of his company’s Q1 activity for clientele and anything at all they can leverage to guidance these initiatives will even more pace-up the evaluation.

“Using CodeQL with some of the added guidance presented by Microsoft could be the start out of building a significantly additional defensive posture when aiming to build safe items,” Barratt said. “It can be built-in into the improvement pipeline, but also has the opportunity to be leveraged as element of the assessment of other 3rd-party code that could have a ‘copycat’ attack. While that’s great in the shorter-phrase, the authentic benefit is the knowledge this will travel throughout the local community just for the reason that of Microsoft’s broad access. This will assistance result in answers to the ‘where do we start’ problem.”

Lamar Bailey, senior director of security investigate at Tripwire, welcomed Microsoft’s transfer, expressing it was a optimistic for the entire cybersecurity marketplace.

“Through better collaboration and partnerships, we will start to see the fight swing in our favor and put an conclude to major cyberattacks like the ones we have witnessed these previous months,” Bailey reported.
