Sainsbury's Bank web pages stuck on crappy 20th century crypto

'Someone there should be beaten to a pulp with a keyboard'


Update Sainsbury's Bank website still relies on insecure cryptography protocols that more security conscious organisations have abandoned as obsolete.

The UK supermarket-owned bank’s "secure" site rates an “F” in tests using the industry standard Qualys’ SSL Labs service – chiefly because of the support for protocols security experts reckon are well past their sell-by date.

“Shocking really: RC4, SHA-1 cert and other issues,” Mal M, the Reg reader who brought the issue to our attention, commented. “Someone there should be beaten to a pulp with a keyboard.”

The practical upshot here is that Sainsbury's Bank is not following industry best practice, creating an added risk as a result, not that customer details have been exposed much less leaked.

The class of security risk here is one that other UK banks among other organisations have had issues with in the past. ®

Updated to add

In response to queries from El Reg, Sainsbury's Bank stated that customers should have no concern because multiple layers of security make the site safe.

Customers visiting the Sainsbury’s Bank website can rest assured that they are protected at all times by multiple layers of online security. We continually act to strengthen the protection of our online customer services through security improvement initiatives.

    Plus: Yandex releases 100-billion-parameter language model for free, and more

    In brief US hardware startup Cerebras claims to have trained the largest AI model on a single device powered by the world's largest Wafer Scale Engine 2 chip the size of a plate.

    "Using the Cerebras Software Platform (CSoft), our customers can easily train state-of-the-art GPT language models (such as GPT-3 and GPT-J) with up to 20 billion parameters on a single CS-2 system," the company claimed this week. "Running on a single CS-2, these models take minutes to set up and users can quickly move between models with just a few keystrokes."

    The CS-2 packs a whopping 850,000 cores, and has 40GB of on-chip memory capable of reaching 20 PB/sec memory bandwidth. The specs on other types of AI accelerators and GPUs pale in comparison, meaning machine learning engineers have to train huge AI models with billions of parameters across more servers.

  • Zendesk sold to private investors two weeks after saying it would stay public
    Private offer 34 percent above share price is just the thing to change minds

    Customer service as-a-service vendor Zendesk has announced it will allow itself to be acquired for $10.2 billion by a group of investors led by private equity firm Hellman & Friedman, investment company Permira, and a wholly-owned subsidiary of the Abu Dhabi Investment Authority.

    The decision is a little odd, in light of the company's recent strategic review, announced on June, which saw the board unanimously conclude "that continuing to execute on the Company's strategic plan as an independent, public company is in the best interest of the Company and its stockholders at this time."

    That process saw Zendesk chat to 16 potential strategic partners and ten financial sponsors, including a group of investors who had previously expressed conditional interest in acquiring the company. Zendesk even extended its discussions with some parties but eventually walked away after "no actionable proposals were submitted, with the final bidders citing adverse market conditions and financing difficulties at the end of the process."

  • Singapore promises 'brutal and unrelentingly hard' action on dodgy crypto players
    But welcomes fast cross-border payments in central bank digital currencies

    In the same week that it welcomed the launch of a local center of excellence focused on crypto-inspired central bank digital currencies, Singapore's Monetary Authority (MAS) has warned crypto cowboys they face a rough ride in the island nation.

    The center of excellence (COE) was established by the Mojaloop Foundation – an open source effort to create payment platforms to make digital financial services accessible to those without access to banks. The COE aims to "accelerate financial inclusion in emerging markets" through hackathons, workshops and pilot projects while examining expanded CBDCs payment capabilities."

    Singapore's sovereign wealth fund has invested in Mojaloop, and MAS chief fintech officer Sopnendu Mohanty serves as a board advisor and the authority provides representatives to the Foundation's working group, alongside folks from the Bill & Melinda Gates Foundation, Google, and more.
