This Week In Security: XRP Poisoned, MCP Bypassed, And More

April 25, 2025 by 7 Comments

Researchers at Aikido run the Aikido Intel system, an LLM security monitor that ingests the feeds from public package repositories, and looks for anything unusual. In this case, the unusual activity was five rapid-fire releases of the xrpl package on NPM. That package is the XRP Ledger SDK from Ripple, used to manage keys and build crypto wallets. While quick point releases happen to the best of developers, these were odd, in that there were no matching releases in the source GitHub repository. What changed in the first of those fresh releases?

The most obvious change is the checkValidityOfSeed() function added to index.ts. That function takes a string, and sends a request to a rather odd URL, using the supplied string as the ad-referral header for the HTML request. The name of the function is intended to blend in, but knowing that the string parameter is sent to a remote web server is terrifying. The seed is usually the root of trust for an individual’s cryptocurrency wallet. Looking at the actual usage of the function confirms, that this code is stealing credentials and keys.

The releases were made by a Ripple developer’s account. It’s not clear exactly how the attack happened, though credential compromise of some sort is the most likely explanation. Each of those five releases added another bit of malicious code, demonstrating that there was someone with hands on keyboard, watching what data was coming in.

The good news is that the malicious releases only managed a total of 452 downloads for the few hours they were available. A legitimate update to the library, version 4.2.5, has been released. If you’re one of the unfortunate 452 downloads, it’s time to do an audit, and rotate the possibly affected keys. Continue reading “This Week In Security: XRP Poisoned, MCP Bypassed, And More” →

This Week In Security: No More CVEs, 4chan, And Recall Returns

April 18, 2025 by 7 Comments

The sky is falling. Or more specifically, it was about to fall, according to the security community this week. The MITRE Corporation came within a hair’s breadth of running out of its contract to maintain the CVE database. And admittedly, it would be a bad thing if we suddenly lost updates to the central CVE database. What’s particularly interesting is how we knew about this possibility at all. An April 15 letter sent to the CVE board warned that the specific contract that funds MITRE’s CVE and CWE work was due to expire on the 16th. This was not an official release, and it’s not clear exactly how this document was leaked.

Many people made political hay out of the apparent imminent carnage. And while there’s always an element of political maneuvering when it comes to contract renewal, it’s worth noting that it’s not unheard of for MITRE’s CVE funding to go down to the wire like this. We don’t know how many times we’ve been in this position in years past. Regardless, MITRE has spun out another non-profit, The CVE Foundation, specifically to see to the continuation of the CVE database. And at the last possible moment, CISA has announced that it has invoked an option in the existing contract, funding MITRE’s CVE work for another 11 months.

This Week In Security: Recall, Modem Mysteries, And Flipping Pages

June 7, 2024 by 6 Comments

Microsoft is racing to get into the AI game as part of Windows 11 on ARM, calling it Copilot+. It’s an odd decision, but clearly aimed at competing with the Apple M series of MacBooks. Our focus of interest today is Recall, a Copilot+ feature that not only has some security problems, but also triggers a sort of visceral response from regular people: My computer is spying on me? Eww.

Yes, it really sort of is. Recall is a scheme to take screen shots of the computer display every few seconds, run them through character recognition, and store the screenshots and results in a database on the local machine hard drive. There are ways this could be useful. Can’t remember what website had that recipe you saw? Want to revisit a now-deleted tweet? Is your Google-fu failing you to find a news story you read last week? Recall saw it, and Recall remembers. But what else did Recall see? Every video you watched, ever website you visited, and probably some passwords and usernames you typed in.
