Possess God’s Peace
“Until the Spirit is poured on us from on high, and the wilderness becomes a fruitful field, and the fruitful field is considered a forest. Then justice will dwell in the wilderness; and righteousness will remain in the fruitful field. The work of righteousness will be peace; and the effect of righteousness, quietness and confidence forever.” (Isaiah 32:15-17 WEB)
This prophecy declared by the prophet Isaiah is in the process of partial fulfillment. The Spirit has been poured out on us from on high ever since the Day of Pentecost when Jesus first sent His Spirit to baptize the disciples in Jerusalem.
The wilderness represents Israel which has become a fruitful field (the place where salvation starts spreading from), and will eventually become full of life as a forest, during the future Millennial reign of Christ.
Through Jesus’ work of righteousness at the cross, we already have peace with God.
Since we have become the righteousness of God in Christ Jesus, we have an everlasting quietness and confidence in our spirit.
There is no need to struggle or strive to justify ourselves before God or anyone else. We know that the payment has been completed and that God has fully accepted us.
Born-again believers ought to be the most peaceful and quietly-confident people on earth, exuding the kind of regality that Jesus has. This confidence comes from knowing that you are God’s child, lacking nothing and having everything.
This shalom is your portion. Possess this inheritance that the world cannot give. No amount of pills, therapy, or chemicals can produce the peace that is freely ours in Christ.
Today, declare and believe: “I am full of shalom peace, for I was re-created in the image of the Prince of Peace. I possess the peace of God right now, and allow it to flood my soul, body, and life; setting everything right, perfectly integrated with nothing lacking or missing. I receive this in Jesus’ name, Amen!”
Keep studying God’s word and growing in your understanding of His ways. Our Patreon community is currently on a Bible study series called “My Faith Declarations” which looks at the Spirit-inspired utterances of the authors of the Psalms. They wrote about the trials and tribulations they experienced, so the book of Psalms is very relatable.
By turning their faith declarations into our own, we can learn how to overcome similar circumstances in life through faith in the Lord! Become a “God Every Morning” tier or above patron on Patreon to receive this reward, daily devotionals by email, and also all my eBooks.

📜 [專欄新文章] 技術解析台灣交易所BitoPro駭客攻擊

重演2014年的 Partial Payment 漏洞利用,罪咎誰當?
背景
台灣加密貨幣交易所 BitoPro 於台灣時間2019年4月28日上架 Ripple 瑞波幣(XRP)開放交易,並於台灣時間2019年5月1日遭到駭客利用 Partial Payment 特徵進行漏洞攻擊,可能損失達6300萬台幣 (根據 BlockTempo 報導)
漏洞在哪?
漏洞來自於 Ripple 支付的特別功能
Ripple 早期推出多種有別於傳統支付 (Payment) 的交易格式,包含非默認路徑支付 (NoDirectRipple)、部分支付 (PartialPayment)、限定匯率支付 (LimitQuality),並採用特定的支付標籤 (Transaction Flag) 作為標記:
https://developers.ripple.com/payment.html#payment-flags
部分支付:容易忽略的危險設計
部分支付的目的主要用於回彈所有目的未知的付款 (Boucing Payments),有點類似於以太坊智能合約常見的 fallback-revert 功能:
function () { revert();}
對 Ripple 而言,一般常見的支付交易 (Payment) 格式如下:
{ "TransactionType" : "Payment", "Account" : "rf1BiGeXwwQoi8Z2ueFYTEXSwuJYfV2Jpn", "Destination" : "ra5nK24KXen9AHvsdFTKHSANinZseWnPcX", "Amount" : { "currency" : "USD", "value" : "100", "issuer" : "rf1BiGeXwwQoi3Z2ueFYTEXSwuJYfV2Jpn" }, "Fee": "12", "Flags": 2147483648, "Sequence": 2,}
上面的 Amount 欄位用來紀錄此筆紀錄總共涉及多少價值。
而特殊的部分交易 (Partial Payment) 格式則會多出一個欄位 delivered_amount,並取代原先 Amount 來紀錄真正涉及的價值。
"delivered_amount": { "currency": "USD", "value": "1", "issuer": "rf1BiGeXwwQoi3Z2ueFYTEXSwuJYfV2Jpn"}
也就是說,如果交易所或任何機構在接受 Partial Payment 時忘記使用新欄位 delivered_amount,而仍然使用舊的 Amount,就有機會受害…
攻擊發生了
駭客使用部分支付進行攻擊
根據 XRPSCAN 上這筆對 BitoPro 的存入支付,可以看出攻擊者將 Amount 設定在 330,000 XRP (約330萬元台幣),不過實際支付的金額只有右側 Delivered 欄位的 0.003255 XRP (約0.03元台幣),甚至低於此筆支付的手續費 0.005 XRP。
706E3FEC8F44CECB6E85FBE749AD5BC4C9C50BA75A280DCCD211696BE17F64B4
若 BitoPro 接受此轉帳並讀取 Amount 作為存入金額,則駭客將憑空製造330萬元台幣,而這筆錢由誰買單?…就將會是交易所自己。
漏洞無人知曉?
2014年Justcoin交易所遭駭
2014年10月8日挪威的 Justcoin 交易所遭到駭客利用部分支付漏洞攻擊。
Stellar 已改善此功能
源自於 Ripple 設計的恆星幣 Stellar 因具有與 Ripple 同樣的部分支付設計,但在觀察到其帶來的實作風險時,已在Justcoin遭駭後三天內改善此功能。
Ripple 持續使用此功能
部分支付是個特徵而不是個錯誤。
“It is not a bug. It’s a feature.”
只能由官網上看到幾篇提醒使用者的說明:[1] 與 [2]。
今後如何預防
每天詳讀 Ripple 的特徵公佈欄
加強 KYC 與 Sanity Checks
閱讀大量區塊鏈攻防新聞:XRP Chat, BlockTempo, ZyCrypto, SlowMist, 與 BlockThreat
