CISA confirms hackers are actively exploiting critical ‘Citrix Bleed 2' bug
Security researchers have dubbed the bug 'Citrix Bleed 2' for its similarity to a 2023 security flaw in Citrix NetScaler, a networking product that large companies and governments rely on for allowing their staff to remotely access apps and other resources on their internal networks. Much like the earlier bug, Citrix Bleed 2 can be remotely exploited to extract sensitive credentials from an affected NetScaler device, allowing the hackers broader access to a company's wider network.
In an alert on Thursday, CISA said it had evidence that the bug was being actively used in hacking campaigns, adding to the raft of research and findings pointing to widespread exploitation, with some reporting hacks dating back as far as mid-June. Akamai said it saw a 'drastic increase' in efforts to scan the internet for affected devices after details of the NetScaler exploit were published earlier this week.
CISA said the NetScaler bug poses a 'significant risk' to the federal government's systems, and ordered federal government agencies to patch any Citrix device affected by the bug by Friday.
For its part, Citrix has not yet acknowledged that the vulnerability is being exploited. The company's security advisory urges customers to update affected devices as soon as possible.
Citrix representatives did not respond to TechCrunch's request for comment.

Tyson Foods hasn't seen 'material' impact from Trump tariffs as consumer protein push lifts results
Tyson Foods (TSN) reported results Monday that were better than expected for its fiscal third quarter. A consumer focus on protein and a lack of immediate impact from President Trump's tariff policies boosted results. "Consumers are prioritizing protein ... over other foods, but they're also prioritizing food as essential versus the non-essential things like apparel, ... bigger ticket items," Tyson Foods CEO Donnie King said. As far as the impact of President Trump's tariffs, King said, "I would not call anything we've seen from tariffs today, not only beef, but in pork, chicken. I don't see a material impact from that at this point." In the quarter, Tyson reported sales grew 4% to $13.88 billion, topping forecasts for revenue to tally $13.55 billion, according to Bloomberg data. Adjusted earnings per share were $0.91 in the quarter, ahead of forecasts for $0.78. The company also said its sales for its fiscal year 2025, which wraps up during the current quarter, will rise 2% to 3% from last year, better than its previous outlook for sales to be flat to up 1%. Tyson Foods stock rose about 3% following the results on Monday. Year to date, the stock remains down over 5%, trailing the S&P 500's roughly 7.5% gain. Read more: Live coverage of corporate earnings Chicken was the company's strongest category during the quarter, with volumes rising 2.4% alongside an average price increase of 1.1%. Consumers leaned into frozen items like Tyson Simple Ingredient nuggets, which have higher protein. Tyson's fresh chicken business grew volume by 2.3%. Tyson now expects its chicken segment to post operating income of $1.3 billion to $1.4 billion for the year, up from the previously expected range of $1 billion to $1.3 billion. "Our chicken business is obviously running a lot better than it has," King said. "This has been a multiyear journey, but it's running more efficiently." King said the company is also seeing the benefit from the closure of four chicken plants two years ago. Its pork business is having a moment too. Volume for that segment grew 1.5% against forecasts for a 2.3% decline. Pork delivered its strongest third quarter adjusted operating income for the company in four years. All the momentum offset a more challenging quarter for its beef business. The average price for beef increased 10%, higher than the 7.3% jump expected. Volumes declined 3.1%, more than the 2% expected, as the tightened cattle supply made fewer available for Tyson to buy and drove costs higher. Still, King said its beef consumer "has been very resilient" in the face of higher prices. For ranchers, higher beef prices have been good news, according to Texas A&M professor David Anderson, as these prices reverse the situation "for ranchers who have dealt with low prices, high costs, and drought in recent years." Fewer imports from Mexico have hit the US cattle supply, however, creating another challenge for Tyson. "I expect the tariff and retaliatory tariffs from China have introduced more struggles in [the ranchers'] business," Anderson said. "I should say it's not just high prices but fewer cattle that make it hard to get enough cattle to operate." Brooke DiPalma is a senior reporter for Yahoo Finance.

Analyst downgrades top S&P 500 stock after disappointing earnings
Analyst downgrades top S&P 500 stock after disappointing earnings originally appeared on TheStreet. Compass Point has lowered Coinbase's (Nasdaq: COIN) price target from $330 to $248 and downgraded the rating from "Neutral" to "Sell" after the crypto exchange reported disappointing financial results for the second quarter of 2025. The investment firm indicated receding retail interest, poor Q2 records, weak prospects for recurring revenue lines like subscriptions and custody services the next quarter, and more competition from stablecoin and decentralized finance (DeFi) platforms as the reasons it downgraded the COIN stock's rating. Compass Point also warned of Coinbase's retail trading under pressure despite a bullish crypto market. Notably, retail trading is Coinbase's main profit are two other factors that the firm highlighted as possible risks for Coinbase. One is a potential delay in the CLARITY Act, which deals with classifying the financial status of crypto assets. Another is Coinbase trailing Robinhood (Nasdaq: HOOD) and Kraken in launching stock trading. 'We see limited support for COIN's valuation if crypto markets sell off further,' said Compass Point. Founded in 2012, Coinbase is the largest crypto exchange in the U.S. The company, which went public in April 2021, joined the S&P 500 list in May 2025 — the only crypto stock to be included in the hotly contested list so far. During Q2 2025, the exchange generated $1.5 billion in total revenue, $1.4 billion in net income, and earnings per share (EPS) of $5.14 in Q2. The exchange held 11,776 Bitcoin worth $1.3 billion by the end of the quarter. The COIN stock is trading at $319.55 at the time of writing, up 1.54% a day.

Former Obama adviser quips that Trump is ‘combing Fox News' for new Labor Stats chief after firing
After Donald Trump's pledge to nominate a new Bureau of Labor Statistics commissioner in the next few days, former Obama adviser David Axelrod joked that the president is 'probably combing Fox News' for a replacement. Following a weak jobs report Friday that found not only did the U.S. economy add only 73,000 jobs in July but that the 258,000 fewer jobs were created in the previous two months, the president announced that he had axed the chief labor statistician Erika McEntarfer. 'I believe the numbers were phony, just like they were before the election, and there were other times,' the president told reporters over the weekend when pressed on his decision. Since then, Trump has repeatedly and baselessly claimed that the jobs report 'was RIGGED' and that McEntarfer – who was appointed by his predecessor Joe Biden – had manipulated the numbers to make him 'look bad.' While the president has faced some criticism from Republican lawmakers for firing McEntarfer, who was overwhelmingly confirmed by the Senate last year, White House officials were tasked over the weekend with justifying and defending Trump's rash move. Their efforts were met with mockery and ridicule from cable news outlets and editorial boards. The Wall Street Journal labeled the president's economic adviser the 'bureau of labor denial' while Morning Joe host Joe Scarborough claimed that Trump's aides had to 'put on their Baghdad Bob hat this weekend because there was no justification for' the firing. Axelrod, who now works as a CNN senior political commentator, took a decidedly snarky tone over the news that Trump would soon offer up a replacement for McEntarfer. Sharing a New York Times article that noted the president had told reporters he'd announce a new BLS commissioner 'over the next three or four days,' Axelrod tweeted Sunday: 'He's probably combing Fox News right now for a qualified replacement.' Of course, Axelrod – who served as a senior advisor to former President Barack Obama and helped run his two presidential campaigns – was referencing Trump's penchant for using the conservative cable giant to staff up his administration. Trump created a revolving door between Fox News and the White House during his first term in office, and his second term has seen roughly two dozen former Fox News employees take on roles in the administration – with several of them filling Cabinet-level jobs. Axelrod wasn't the only one who jokingly suggested that the president would look for a loyalist to lead the Bureau. George Conway, the former GOP lawyer who has become a leading anti-Trump critic in recent years, created a fake White House press release announcing that the president had named former Trump Organization CFO Allen Weisselberg to be the next Labor Stats chief. Weisselberg pleaded guilty to charges of grand larceny, criminal tax fraud and falsifying business records in 2022. He also later pleaded guilty to perjury charges for lying under oath in a New York civil trial. In his newsletter, The Atlantic contributing writer Derek Thompson argued that Trump was waging a war against reality, adding that weak job growth wasn't 'the only inconvenient statistic that the Trump administration has tried to suppress in its first seven months.' As Thompson pointed out, the administration has also dismissed scientists in charge of vaccine evaluations at the CDC and gotten rid of experts who put together national climate assessments so insurance companies can gauge risk, not to mention the firing of McEntarfer. In a wild post on Truth Social Monday morning, Trump claimed that he was the victim of 'FAKE' numbers that were meant to hide the economic success of his tariff policies. 'Last weeks Job's Report was RIGGED, just like the numbers prior to the Presidential Election were Rigged. That's why, in both cases, there was massive, record setting revisions, in favor of the Radical Left Democrats,' he wrote. 'Those big adjustments were made to cover up, and level out, the FAKE political numbers that were CONCOCTED in order to make a great Republican Success look less stellar!!! I will pick an exceptional replacement. Thank you for your attention to this matter. MAGA!'
