LTC Latest Hack Target
The Daily Crypto Update for Institutional Investors
In the latest crypto security incident, the Litecoin (LTC) network suffered a denial-of-service attack over the weekend - We examine the incident & discuss LTC in this AM’s note
What happened? The weekend security incident caused a 13-block chain reorganization that reversed roughly 32 minutes of activity. According to public reporting, the attack combined two elements: a consensus bug that allowed an invalid transaction to slip through, and a denial-of-service attack aimed at miners who were operating updated software that would have caught the invalid transaction. This appears to have created a window in which miners running the older version of the software produced a chain containing invalid transactions, while miners that had installed the fix were temporarily taken offline. Once the denial-of-service pressure eased, the valid chain reasserted itself and the network reorganized to the valid chain, reversing the invalid activity. The Litecoin Foundation has not disclosed how much LTC was involved in the invalid transactions.
What is Litecoin? With a market cap of USD 4.27B, LTC is the 22nd largest cryptocurrency. Launched in 2011, Litecoin is one of the earliest cryptocurrency networks, created as a faster, lighter version of BTC, designed to enable low-cost, peer-to-peer digital payments. Some 15 years since LTC’s launch, its pitch to investors is likely much less clear compared to its inception. BTC has developed layer-2 solutions for low-cost peer-to-peer payments. Stablecoins have also emerged as a new payment method beyond just crypto while offering the relative price stability of the US dollar. Moreover, as the aforementioned security incident suggests, LTC is subject to significant technical risks. In this context, despite its seniority in the crypto world, LTC belongs to a cohort of digital assets with highly questionable market caps. While LTC has seen an ~81% correction from its 2021 record of USD 23.17B, the asset does continue to underscore the persistence of questionable market caps in the crypto space.
Crypto investors have proven willing to overlook technical risks: In 2020, we described how ETH Classic, which had a market cap of USD ~1B at the time, had suffered a spate of ‘51% attacks.’ The exploit, which involves gaining control of at least 50% of a network’s hash power, essentially means a blockchain stops acting as a record of truth. We wrote at the time, ‘it is nothing short of shocking that the price has not declined further in ETC.’ This observation has held true for a plethora of assets and security incidents. LTC, for instance, saw no discernible price reaction to the weekend’s event. Moreover, given the limited attention the event received on social media, and the lack of a DeFi ecosystem built on Litecoin, it’s unclear if the attack will garner in-depth analysis like the Kelp DAO exploit. This raises the prospect that Litecoin holders will never fully get a full picture of the incident nor its potential for occurring again in the future.
The crypto space remains characterized by novel security challenges: Recent weeks have seen several unique security incidents in the crypto space. Just the month, beyond the Kelp DAO incident, the Drift Protocol suffered a USD 286M hack and a fake Ledger Live app on Apple’s App Store resulted in the loss of USD 9.5M worth of assets. The LTC attack, whose extent remains unclear, is the latest incident this month underscoring the persistent novel security challenges in the crypto space.
