AI and cloud briefing: Meta enters the AI coding race, plus a Russian state group exploiting Zimbra email servers

Here is our latest round-up of what matters in AI and cloud for UK businesses. It is short and factual, with links to credible sources so you can read further.

Lead story: Meta enters the AI coding race with Muse Spark 1.2 and Muse Code

Meta has launched Muse Spark 1.2, a new coding-focused language model, alongside Muse Code, its first terminal-based coding agent, built by Meta Superintelligence Labs. Muse Spark 1.2 is trained to handle full software engineering workflows rather than just code completion, with more training compute spent on coding tasks and a wider range of development environments. Muse Code runs on top of the model and uses persistent background agents that can plan, write and check changes across large codebases, currently in beta on macOS and Linux. Further coverage is available from MarkTechPost and TestingCatalog.

What is significance: this puts Meta directly into the AI coding tools market alongside OpenAI’s Codex, Anthropic’s Claude Code and Google’s coding agents. For businesses, it means more competition and more choice in this space, which usually leads to faster improvement and more competitive pricing. It is also a sign that background, semi-autonomous coding agents, not just autocomplete-style assistants, are becoming the standard direction for this category.

Our advice this week:

• If you are evaluating AI coding tools, treat this as a fast-moving market and revisit your choice every few months rather than committing long term to one vendor.
• Background coding agents can make real changes to code with limited supervision, so keep them working in branches with mandatory review before anything reaches production.
• Ask any AI coding vendor what data from your codebase is used for training or logging, and confirm this meets your company’s data handling rules.

Cyber security alert: Russian state-backed group exploiting a Zimbra email flaw

CISA, the NSA, the FBI and international partners have issued a joint advisory warning that a Russian state-supported group known as Laundry Bear is actively exploiting a zero-click flaw, CVE-2025-66376, in Zimbra Collaboration Suite webmail. The attack only requires a target to view a malicious email; no click is needed. The group uses a custom tool called Ulej to pull out email content, passwords and two-factor authentication tokens. More than 10 organisations, including defence, government, law enforcement and technology bodies, have been targeted since July 2025. A fix is available in Zimbra versions 10.1.13 and 10.0.18. Further detail is available from BleepingComputer and Help Net Security.

What is significance: a zero-click flaw is especially dangerous because there is no phishing link or attachment for staff to avoid, simply viewing an email in a vulnerable webmail client is enough. Any organisation running Zimbra should treat this as urgent.

Our advice: if you or a supplier runs Zimbra Collaboration Suite, update to 10.1.13 or 10.0.18 immediately, check mailbox audit logs for unusual access, and reset credentials and 2FA tokens for any account that may have been exposed.

Cloud: AWS and Google Cloud launch a joint multicloud initiative as Google Cloud growth hits 82%

AWS and Google Cloud have launched a joint multicloud collaboration, making it easier for businesses to connect and run workloads across both platforms, with Microsoft Azure expected to join later in 2026. The move comes as Google Cloud reported revenue of $24.8 billion for the most recent quarter, up 82% year on year and accelerating from 63% growth the quarter before, according to coverage from CIO Dive. Microsoft’s Azure has grown around 40% for two consecutive quarters, and AWS holds roughly 31% of the global cloud market.

What is significance: all three hyperscalers are now competing hard on AI infrastructure, not just storage and compute, and easier multicloud connections lower the cost and complexity of using more than one provider. For businesses already spread across AWS, Google Cloud and Azure, this should mean fewer networking headaches over time. It is also a reminder that cloud pricing and capability are moving quickly, so contracts and architecture choices are worth revisiting periodically rather than left on autopilot.

Also in AI security: a fake video-game puzzle tricks AI browsers into leaking passwords

Security researchers at LayerX have demonstrated an attack called BioShocking that manipulates AI browser agents into ignoring their safety rules. The researchers built a web page with a rigged puzzle that rewarded the AI for accepting deliberately wrong answers. Once an agent accepted that wrong answers were fine, it stopped treating its safety rules as fixed, and could then be directed to a page that redirected to the user’s own signed-in accounts, from where it copied out credentials. The technique worked against six agentic browsers and plugins, including OpenAI’s ChatGPT Atlas, Perplexity’s Comet, and Anthropic’s Claude extension. Further coverage is available from The Hacker News and Infosecurity Magazine.

What is significance: as AI browser agents become more common for everyday tasks, this shows that their safety guardrails can be undermined through indirect means, not just direct instructions to misbehave. Any business piloting AI browser agents for staff should treat this as an active risk category, not a theoretical one.

Our advice: avoid letting AI browser agents operate on the same browser profile as important accounts such as source code repositories, banking, or admin panels, and review vendor guidance on prompt injection defences before wider rollout.

The takeaway

Four stories, one thread: AI capability, cloud infrastructure and the risks around both are all moving quickly at once. Meta joining the AI coding race and the AWS-Google multicloud tie-up show real competition and investment continuing to build useful tools faster and cheaper. At the same time, a state-backed group exploiting email servers with no user click required, and researchers showing AI browsers can be talked out of their own safety rules, are reminders that the attack surface is growing alongside the capability. Businesses that patch known flaws quickly, keep AI agents away from sensitive accounts and systems, and periodically reassess their cloud and AI vendor choices will be better placed than those standing still.
