What are the security hazards of open-sourcing the Twitter algorithm? ...

Elon Musk has announced his intention to open source the Twitter algorithm to increase the length of time it takes for applications to promote or demote posts.

The decision has triggered a heated debate on all sides, as well as in the security industry, where experts are divided on whether open sourcing the algorithm will be a net positive for security or not.

According to critics, Musk''s intention to send Twitter open source might highlight vulnerabilities on the scale of Log4Shell and Spring4Shell. For supporters, the decision could even improve the security of the platforms.

The bad: Attackers may have the option to select entry points.

One of the greatest security risks of allowing the code to open-source is that it provides threat actors with the opportunity to examine it for security limitations.

Open[ing] up Twitter''s recommendation algorithms is a two-edge sword. While having more eyes on the code can increase security, it also opens the door for malicious researchers to gain insights they wouldn''t normally have, according to Mike Parkin, a senior technical engineer at Vulcan Cyber.

Parkin, a cyberrisk management specialist, believes that introducing the recommendation algorithm might help disinformation dissect on the platform even further as interested parties learn to manipulate it and sidestep moderators checks and balances while giving users multiple versions of the platform to patch.

The good: Increased transparency to mitigate issues

Other analysts and security experts discuss the discussion on the other side of the issue. Steering transparency on the platform is a positive, because it gives the platform''s users the possibility to play an important role in vulnerability management.

Instead of Twitter having a small team of researchers coping with problems, opening the code might potentially provide them with support from tens of thousands of users, who can help improve the platform''s security and integrity.

When it comes to discovering vulnerabilities in software, access to source code is similar to that of having access to an MRA when it comes to illness. According to Casey Ellis, the inside-out perspective will always be more useful and complete than one formed by looking only from the outside in.We see this every time in crowdsourced security testing, and the security advantage for Twitter is more thorough feedback from the crowd about issues.

Ellis adds that while it gives attackers an opportunity to discern vulnerabilities, whether security implications are positive or negative will be attributed to Twitter''s ability to invest vulnerability information and rectify flaws before they are exploited.

How enterprises can help mitigate the risks

While it remains unclear what the effects of open sourcing the algorithm will have, there are still a few steps that organizations can take to mitigate the risks.

Tim Mackey, a senior security strategist at Synopsys Software Integrity Group, believes that an open-source governance program will assist in addressing the issues effectively.

Businesses may mitigate some of the risk by identifying which open-source components are influencing the Twitter open-source technologies and then implementing an open-source governance program for them. This is similar to the proactive approach used by some businesses in helping them minimize their exposure to the Log4Shell vulnerability.

Mackey advises firms to create an open-source governance program for open-source components that power Twitters technologies, and to actively monitor for new vulnerability disclosures, so that security teams are prepared to address them.
