Tectonic attacker sends 2,659 ETH to Tornado Cash, capping a record hack year
The destination is important much beyond Cronos. Tornado Cash is still the biggest mixer in Ethereum-based networks and this makes the transaction of interest to exchanges, investigators and traders who trace stolen cryptocurrency.
The only money the rollback could not touch
When Tectonic, the largest lending platform of Cronos, was depleted on August 30, validators brought the network to a halt in less than no time. Cronos restored the chain to the point prior to the attack and resumed block generation from the block number 90,896,189.
The rollback erased nearly all balances associated with the attacker on Cronos but it could not reverse any funds that had already made their way to Ethereum.
As reported by The Defiant, at the time, the Ethereum balance reached 2,592.2152 ETH, which converted into $6.29 million. The data provided by TRM Labs indicated that the hacker initially moved those funds off Cronos by means of USDC before converting them into about 2,500 ETH.
For this article, the figure of $75 million is used based on what is reported by TRM Labs and on-chain researcher Weilin Li. Peckshield’s figure of around $74 million is the rounded-up value of the funds from the three tracked addresses.
Whereas, the figure of $119.5 million is a result of a larger archive-node reconstruction that includes the contract set up by the hackers before the exploit took place.
A 100x pump that hollowed out Cronos’s biggest lender
The attack targeted a token that lacked significant depth in the market. TRM Labs stated that TONIC only had $305,000 in trading volume in the week before the hack, although it had a 20% collateral ratio.
According to Halborn, the hacker increased the price of TONIC by around 100 times within 20 minutes and used the inflated version of the token to leverage harder assets from nine lending protocols.
Earlier reports by Cryptopolitan indicated that the estimated amount of funds lost had increased from approximately $66 million to around $75 million once a second attacker’s wallet was found by Li. Tectonic total value locked (TVL) dropped from approximately $121.7 million before the hack to around $3 million, according to DeFiLlama.
Why a $6.65 million deposit ripples past Cronos
The Tornado Cash deposit is small compared with the broader crypto market, but its route is significant. TRM Labs reported that Tornado Cash had received more than $700 million in 2026 by June and remained the largest mixer on Ethereum-based networks.
TRM has also documented its use by ransomware groups, cybercriminals and North Korea’s Lazarus Group, while noting that the protocol has legitimate privacy uses. The US Treasury removed Tornado Cash from its sanctions list on March 21, 2025.
Cronos’s response raised another issue: finality. Halborn said the rollback reduced the damage but came with a cost to confidence in ledger immutability. Cryptopolitan reported CRO falling about 10% over 24 hours during the initial fallout, while CoinMarketCap later linked continued weakness to the exploit, halt and rollback.
A record year for price-manipulation attacks
Tectonic fits a broader security trend. PeckShield counted 50 major hacks in August, up 67% from July’s 30, although total losses fell 49.5% to $136.3 million from $270 million. Tectonic was August’s largest incident and ranked as the fourth-largest crypto theft of 2026 at the time.
TRM Labs says price-manipulation exploits have already reached an all-time high in 2026, with 32 recorded so far.
The weakness is not always faulty code. When thinly traded collateral is given meaningful borrowing power, attackers can target the price a protocol trusts. Tectonic shows how quickly that risk can spread—from an illiquid token, to a lending protocol, to a chain rollback, and eventually into the cross-chain laundering ecosystem.

Updated: Delta Air Lines warns that as fuel prices hit profits, airline capacity will tighten further
Delta Airlines lowers its annual profit forecast due to an expected increase in fuel costs to $6 billion. The CEO stated that ticket prices have risen by about 20% this year, with limited passenger resistance. Analysts warn that maintaining high ticket prices in 2027 is critical for improving profitability. The article includes comments from the earnings call and analyst remarks. Rajesh Kumar Singh/Shivansh Tiwary, Reuters Chicago, October 9 - Delta Airlines (DAL.N) said on Friday that, despite strong travel demand and rising ticket prices, soaring fuel costs have forced it to cut its 2026 profit expectations by nearly a quarter. So, the airline industry may need to further limit flight growth next year to protect profitability. This warning highlights the increasingly tough challenges faced by U.S. airlines. While strong demand and restricted seat growth have allowed airlines to significantly raise ticket prices and offset higher fuel costs, aggressively increasing flights to capture more demand may intensify competition, making it harder to maintain high fares and protect profits. Based in Atlanta, Delta now expects its annual fuel expenditure to increase by about $6 billion compared to last year—about $2 billion higher than its July forecast—due to the Iran war (link) causing global jet fuel prices to spike. Airlines worldwide are preparing for a prolonged fuel shock. Michael O’Leary, CEO of Ryanair Group RYA.I, said Thursday that high jet fuel prices could persist for another 12-18 months (link), adding more pressure on airlines to raise fares and control costs. https://www.reuters.com/graphics/AUTOMATED-20261008/A4A-JET-FUEL-DAILY-1Y/xmpjwjnmbvr/chart.png “In a high-cost environment, you can’t simply grow your way out,” Delta CEO Ed Bastian said on the earnings call. He noted that the industry has already taken steps to restrict capacity, but more measures will be needed next year to improve profitability. Bastian said Delta raised ticket prices about 20% this year, and passenger resistance has been limited. He is confident that even if fuel costs eventually drop, the high fares can still be maintained. Delta lowered its adjusted annual earnings per share forecast from the July prediction of $6.50-$7.50 to $5.10-$5.60. According to LSEG data, the midpoint of the new range is below analysts’ average expectation of $5.46. Third-quarter adjusted earnings per share were $1.72, four cents below analysts’ average forecast. In midday trading, shares of Delta dropped 1.7%, United Airlines UAL.O fell 1.4%, and both American Airlines AAL.O and Southwest Airlines LUV.N were down about 1%. Delta partly shields itself from rising fuel costs by owning a refinery outside Philadelphia (link), which is expected to generate over $700 million in profits this year. Even with this buffer, the airline expects its fourth-quarter fuel price to rise from $3.61 per gallon in Q3 to $4.25 per gallon. Delta forecasts adjusted fourth-quarter earnings per share to be between $1.15-$1.65, with the $1.40 midpoint roughly matching analysts’ average expectation of $1.39. Fare increases Government data shows that in the first eight months of 2026, U.S. airlines spent $42.9 billion on fuel, an increase of $13.2 billion compared to the same period last year despite slightly reduced consumption. According to the U.S. Bureau of Labor Statistics, strong demand and limited seat growth pushed average U.S. airline ticket prices up by about 25% year-on-year between April and August. https://www.reuters.com/graphics/USA-AIRLINES/FUEL/lbpgdnbzwvq/chart.png Analysts at Melius Research said that despite surging fuel costs, Delta’s ability to raise fares helps keep second-half profits roughly stable. Still, they warn that the company’s profit margin has struggled to improve over the years. “It is critical for margin improvement to maintain or raise fares in 2027,” they wrote in their research report. With industry capacity growth expected to accelerate in Q4, this challenge will likely become even tougher. Deutsche Bank analysts expect the proportion of fuel costs recouped through revenue measures to fall in Q4 and predict full recovery won’t happen until early 2027. Bastian noted that low industry returns are another reason for limiting capacity growth. He said Delta will be cautious with its 2027 capacity plan until the fuel price outlook becomes clearer. He added that international routes may account for a larger share of Delta’s capacity expansion compared to domestic routes. Currently, Delta says its premium cabins and corporate travel business remain strong, and its economy cabin business is gradually improving. With Q4 ticket bookings already exceeding 60%, Delta expects revenue to increase about 20% year-on-year, despite limited capacity growth. Executives said early booking trends for Q1 2027 are also encouraging. (For the convenience of non-native English speakers, Reuters automatically translates its reports into several
