Rackspace customers grapple with “devastating” email hosting price hike
Rackspace’s new pricing for its email hosting services is “devastating,” according to a partner that has been using Rackspace as its email provider since 1999.
In recent weeks, Rackspace updated its email hosting pricing. Its standard plan is now $10 per mailbox per month. Businesses can also pay for the Rackspace Email Plus add-on for an extra $2/mailbox/month (for “file storage, mobile sync, Office-compatible apps, and messaging”), and the Archiving add-on for an extra $6/mailbox/month (for unlimited storage).
As recently as November 2025, Rackspace charged $3/mailbox/month for its Standard plan, and an extra $1/mailbox/month for the Email Plus add-on, and an additional $3/mailbox/month for the Archival add-on, according to the Internet Archive’s Wayback Machine.
OpenAI to test ads in ChatGPT as it burns through billions
On Friday, OpenAI announced it will begin testing advertisements inside the ChatGPT app for some US users in a bid to expand its customer base and diversify revenue. The move represents a reversal for CEO Sam Altman, who in 2024 described advertising in ChatGPT as a "last resort" and expressed concerns that ads could erode user trust, although he did not completely rule out the possibility at the time.
The banner ads will appear in the coming weeks for logged-in users of the free version of ChatGPT as well as the new $8 per month ChatGPT Go plan, which OpenAI also announced Friday is now available worldwide. OpenAI first launched ChatGPT Go in India in August 2025 and has since rolled it out to over 170 countries.
Users paying for the more expensive Plus, Pro, Business, and Enterprise tiers will not see advertisements.
Mandiant releases rainbow table that cracks weak admin password in 12 hours
Security firm Mandiant has released a database that allows any administrative password protected by Microsoft’s NTLM.v1 hash algorithm to be hacked in an attempt to nudge users who continue using the deprecated function despite known weaknesses.
The database comes in the form of a rainbow table, which is a precomputed table of hash values linked to their corresponding plaintext. These generic tables, which work against multiple hashing schemes, allow hackers to take over accounts by quickly mapping a stolen hash to its password counterpart. NTLMv1 rainbow tables are particularly easy to construct because of NTLMv1’s limited keyspace, meaning the relatively small number of possible passwords the hashing function allows for. NTLMv1 rainbow tables have existed for two decades but typically require large amounts of resources to make any use of them.
New ammo for security prosOn Thursday, Mandiant said it had released an NTLMv1 rainbow table that will allow defenders and researchers (and, of course, malicious hackers, too) to recover passwords in under 12 hours using consumer hardware costing less than $600 USD. The table is hosted in Google Cloud. The database works against Net-NTLMv1 passwords, which are used in network authentication for accessing resources such as SMB network sharing.

TSMC says AI demand is “endless” after record Q4 earnings
On Thursday, Taiwan Semiconductor Manufacturing Company (TSMC) reported record fourth-quarter earnings and said it expects AI chip demand to continue for years. During an earnings call, CEO C.C. Wei told investors that while he cannot predict the semiconductor industry's long-term trajectory, he remains bullish on AI.
TSMC manufactures chips for companies including Apple, Nvidia, AMD, and Qualcomm, making it a linchpin of the global electronics supply chain. The company produces the vast majority of the world's most advanced semiconductors, and its factories in Taiwan have become a focal point of US-China tensions over technology and trade. When TSMC reports strong demand and ramps up spending, it signals that the companies designing AI chips expect years of continued growth.
"All in all, I believe in my point of view, the AI is real—not only real, it's starting to grow into our daily life. And we believe that is kind of—we call it AI megatrend, we certainly would believe that," Wei said during the call. "So another question is 'can the semiconductor industry be good for three, four, five years in a row?' I'll tell you the truth, I don't know. But I look at the AI, it looks like it's going to be like an endless—I mean, that for many years to come."
