Supporters of BTCPay Server, the open-source bitcoin payments processor that recently disclosed an exploit, have committed to supporting a recovery bounty of 10% of any funds recovered, capped at 3 BTC for full recovery, according to an announcement on Monday.  BTCPay Server announced on Friday that a critical vulnerability was being actively exploited and urged users to update their servers to version 2.4.2. In a security advisory, the firm noted that all BTCPay versions “prior to 2.4.2, including 2.4.2 release candidates” were vulnerable to the attack.  “The vulnerability allowed an attacker to obtain LND admin macaroon credentials from affected instances and use them to access connected LND wallets,” the project wrote on X.

Bitwise CIO: Bitcoin to End Year 'Significantly Higher'

Bitwise CIO Matt Hougan expects Bitcoin to finish the year significantly higher.  Ethereum Price Analysis  “Bad news has stopped moving the market, Hougan said. ”The sellers are gone. When bad news stops moving the market, that marks the bottom, he added.  Hougan also argued that institutional exposure to Bitcoin has continued to grow.  According to the Bitwise executive, the amount of Bitcoin allocated by institutions under a conventional 1% portfolio-allocation framework has effectively risen to between 4% and 5%.  Bitcoins largest holders are accumulating again  In the meantime, data from blockchain analytics platform Santiment shows that the number of wallets holding at least 10,000 BTC is rebounding to a six-month high.  According to Santiment, 90 wallets now hold at least 10,000 BTC, representing a net increase of six such wallets over the past eight weeks, or a 7.1% rise.  At the same time, smaller wallets have been losing their share of Bitcoins supply during August. Santiment attributed some of the resulting retail pessimism to concerns surrounding the recent Coldcard hacks and delays surrounding the Clarity Act.  Bitcoin supply is increasingly moving toward its largest holders, as the data shows.

Hidden Text in PDFs Is Hijacking This AI Assistant

In briefSecurity company PromptArmor says the Rovo AI assistant can be steered to exfiltrate data with no human approval, via hidden instructions in an uploaded file, like PDFs.The trick works even when an org disables Rovos web search, because the URL-opening tool stays live.Atlassian, the maker of Rovo, got the report on May 23 and went quiet; two months on, Rovo “remains vulnerable,” the security firm says.  Remember when black-hat SEOs stuffed web pages with white-on-white keywords—invisible to readers, readable to Google—to game the search rankings? Hackers are doing the same thing with AI models now. The attacker hides instructions inside a PDF document, the model cant tell the difference between the users words and the planted ones, and it obeys.  Per PromptArmors disclosure, Rovo—Atlassians agent that reaches across Jira, Confluence, and the rest of your workspace—can be turned into a data pipeline with a single poisoned file. A victim asks Rovo to organize some tickets, uploads a document, and the document is carrying a concealed prompt (for example an instruction written in transparent color and a font at 1pixel in size).  The eye can‘t see it, but an Agent recognizes that text as another text in the document. That prompt tells Rovo

Tessera brings private B2B settlement to Sui  In an Aug. 10 X thread, Sui presented Tessera as a closed settlement network for businesses. Approved members can settle invoices using a confidential stablecoin without publishing the value of each transaction onchain.  Meet Tessera, a B2B settlement network.

However, the amount appears encrypted to outside observers.  “Institutions wont settle on rails where competitors can see pricing and volume,” Sui said.
