So what info does WinXP really send to MS?

Germany's tecChannel explains


Germany's tecChannel has launched an English-language version of its site, and has celebrated with a seriously trainspotter analysis of the interaction between Windows XP's product activation and Redmond central control. Despite (or possibly because of) Microsoft's insistence that the WPA process is completely harmless and doesn't send the company any of your personal data, the system has since its introduction been the subject of much paranoid speculation.

The Register has not entirely shared this paranoia, although we do worry about why Windows installations seem to have a general compulsion to chatter with remote systems without entirely sharing the experience with us. And we also reckon the real worry is what Microsoft might do if people really started to trust it. However, the good news for now is that tecChannel's investigation indicates that WPA's not a threat to privacy, and shows that it sends the following: Product ID, derived from the product key entered during installation; system locale (IDs you to the nearest country); product code, which is the first five digits of the product key; hardware hash, which is based on the hardware in the local computer, but which does not give Microsoft information on this computer's hardware; data from the WPA.DBL file, if one has been created by a previous installation; and the product key itself.

Microsoft is clearly getting some data from the above, but none of it is personal, and if the company were to use it for any purpose at all other than WPA policing, the fields would be pretty narrow. If the hardware hash did send information on the local configuration it would certainly be useful for development and marketing purposes, but it's been specifically designed not to do this, just to use the hardware purely as a mechanism for generating an anonymous ID (trust us on this being true, explaining how this works is a lengthy process, and anyway, we've forgotten).

Having established that WPA in its current form isn't much of a privacy threat, tecChannel comes up with some tantalising speculation. There's a possible method that could, depending on how the WPA servers deal with the hack, be used to activate on more than one computer using just one key. Also, the COM component supports, among other request types, DROPLIC. "'Dropping a license'", says tecChannel, "might be Microsoft terminology for deactivating an installation of Windows XP with the same product key on another computer." Does this mean the ability to remove XP and install it onto another computer is there in the system already?

Copious details of how tecChannel went about the analysis, together with a download of the tools used (these come with the PDF version of the article, which you have to pay for) can be had here. The German version is here. The new English site has around 30 articles up at the moment, and tecChannel tells us it intends to translate two to three articles from the German site a week for it. ®

  • Cheers ransomware hits VMware ESXi systems
    Now we can say extortionware has jumped the shark

    Another ransomware strain is targeting VMware ESXi servers, which have been the focus of extortionists and other miscreants in recent months.

    ESXi, a bare-metal hypervisor used by a broad range of organizations throughout the world, has become the target of such ransomware families as LockBit, Hive, and RansomEXX. The ubiquitous use of the technology, and the size of some companies that use it has made it an efficient way for crooks to infect large numbers of virtualized systems and connected devices and equipment, according to researchers with Trend Micro.

    "ESXi is widely used in enterprise settings for server virtualization," Trend Micro noted in a write-up this week. "It is therefore a popular target for ransomware attacks … Compromising ESXi servers has been a scheme used by some notorious cybercriminal groups because it is a means to swiftly spread the ransomware to many devices."

  • Twitter founder Dorsey beats hasty retweet from the board
    As shareholders sue the social network amid Elon Musk's takeover scramble

    Twitter has officially entered the post-Dorsey age: its founder and two-time CEO's board term expired Wednesday, marking the first time the social media company hasn't had him around in some capacity.

    Jack Dorsey announced his resignation as Twitter chief exec in November 2021, and passed the baton to Parag Agrawal while remaining on the board. Now that board term has ended, and Dorsey has stepped down as expected. Agrawal has taken Dorsey's board seat; Salesforce co-CEO Bret Taylor has assumed the role of Twitter's board chair. 

    In his resignation announcement, Dorsey – who co-founded and is CEO of Block (formerly Square) – said having founders leading the companies they created can be severely limiting for an organization and can serve as a single point of failure. "I believe it's critical a company can stand on its own, free of its founder's influence or direction," Dorsey said. He didn't respond to a request for further comment today.

  • Snowflake stock drops as some top customers cut usage
    You might say its valuation is melting away

    IPO darling Snowflake's share price took a beating in an already bearish market for tech stocks after filing weaker than expected financial guidance amid a slowdown in orders from some of its largest customers.

    For its first quarter of fiscal 2023, ended April 30, Snowflake's revenue grew 85 percent year-on-year to $422.4 million. The company made an operating loss of $188.8 million, albeit down from $205.6 million a year ago.

    Although surpassing revenue expectations, the cloud-based data warehousing business saw its valuation tumble 16 percent in extended trading on Wednesday. Its stock price dived from $133 apiece to $117 in after-hours trading, and today is cruising back at $127. That stumble arrived amid a general tech stock sell-off some observers said was overdue.
