Australia’s Privacy Regulator Sues Optus Over Massive 2022 Data Breach

/in /tarafından

Australia’s privacy regulator, the Australian Information Commissioner (AIC), has filed a lawsuit against Optus, the Singapore Telecommunications-owned carrier, alleging violations of the Privacy Act 1988 related to a 2022 cyberattack that compromised personal data of nearly 9.5 million customers.

The lawsuit names both Singtel Optus Pty Ltd and Optus Systems Pty Ltd as defendants. The AIC claims a separate breach for each affected customer, with potential fines up to A$2.2 million per breach. However, the regulator has not disclosed the total fine amount sought. Optus is currently reviewing the claims but has not yet assessed the financial impact.

The September 2022 cyberattack is considered one of the worst data breaches in Australia’s history, exposing sensitive information including home addresses, passport details, and phone numbers. Around 10 million Australians—about 40% of the population—were affected, and many experienced a significant disruption to mobile, broadband, and landline services.

The breach sparked calls from Prime Minister Anthony Albanese for stronger privacy laws and faster breach notifications, especially to banks. Optus has also faced ongoing criticism due to a 12-hour nationwide network outage in 2023, leading to the resignation of then-CEO Kelly Bayer Rosmarin.

In addition to this legal action, Optus was taken to court by Australia’s domestic media regulator earlier in 2024 over the same cyberattack.

Nvidia Denies Backdoors in Chips, Warns US Against Mandating Location Verification

/in /tarafından

Nvidia (NVDA.O) reiterated in a blog post on Tuesday that its chips do not contain backdoors or kill switches, urging U.S. policymakers to avoid proposals that would require embedding location verification technology in advanced chips. Nvidia warned that such measures would effectively be a “gift” to hackers and hostile actors by creating vulnerabilities.

The statement follows a recent meeting between Nvidia and the Chinese government, which expressed concerns about a U.S. proposal to require chipmakers to include tracking and positioning functions in their products sold abroad, aimed at preventing unauthorized sales to restricted countries. While the White House and U.S. Congress have proposed such measures, no formal rules or technical standards have yet been established.

Nvidia emphasized that backdoors—hidden methods to bypass security controls—pose serious risks. The company stressed, “there is no such thing as a ‘good’ secret backdoor—only dangerous vulnerabilities that need to be eliminated,” reinforcing that their products do not allow remote access or control.

The tech giant warned that embedding backdoors or kill switches in chips would undermine global digital infrastructure and damage trust in U.S. technology worldwide.

Global M&A Reaches $2.6 Trillion in 2025, Driven by AI and Growth Ambitions

/in /tarafından

Global mergers and acquisitions (M&A) have hit $2.6 trillion in the first seven months of 2025 — the highest level since the pandemic-era peak of 2021 — as companies prioritize growth and capitalize on opportunities in artificial intelligence (AI). Despite a 16% drop in the number of transactions compared to last year, total deal value rose 28%, fueled by large-scale U.S. transactions exceeding $10 billion.

Key deals include Union Pacific Corp’s proposed $85 billion takeover of Norfolk Southern and OpenAI’s $40 billion funding round led by SoftBank. These transactions mark a shift from early-year hesitation caused by U.S. tariffs and geopolitical uncertainty, as renewed boardroom confidence and a clearer regulatory environment spur activity.

Industry experts say the M&A landscape is now heavily growth-oriented, with AI adoption and regulatory changes prompting companies to move quickly to avoid falling behind. Compared to August 2021’s $3.57 trillion, current activity is still down 27%, but bankers expect more large deals in the second half of 2025 as executives adapt to market volatility and post-election policy direction.

Healthcare dominated post-pandemic dealmaking, but over the past two years, technology and electronics have taken the lead. AI-driven needs, such as data center infrastructure and cybersecurity, are major drivers — highlighted by Samsung’s $1.7 billion purchase of FlaktGroup and Palo Alto Networks’ $25 billion acquisition of CyberArk. Private equity has also re-entered the market, with major bids like Sycamore Partners’ $10 billion move to take Walgreens Boots Alliance private and competing offers from KKR and Advent for UK firm Spectris.

The U.S. remains the world’s largest M&A market, representing more than half of global deals, while Asia Pacific’s activity doubled from last year, surpassing the pace of EMEA growth.
