CYBER THREATCAST
CYBER THREAT INTELLIGENCE BRIEFING
An attacker exploited The Sandbox bridges on Base and BNB Smart Chain to mint about 14.9 billion unbacked SAND, forcing bridge shutdowns and trading warnings. MoYu also compromised DoFun Android car head units through a legitimate updater, while Coinbase Cartel reportedly expanded its extortion campaign beyond 60 organizations.
The Sandbox exploit involved more than 400 transactions with unbacked SAND. About 14.75 million legitimate SAND was reportedly extracted and converted into roughly 80 ETH, and Blockaid attributed the flaw to the Base minting implementation rather than LayerZero.
BounceBit halted its blockchain after an authorization flaw enabled the transfer of 286.5 million BB tokens, while a Cosmos-EVM exploit stopped MANTRA Chain for about 30 hours. Bridge minting authority, source-account authorization and trusted software updaters merit immediate scrutiny.
Editorial: Recommended Actions
01
PRIORITY
SAND holders, liquidity providers, and trading venues should suspend bridge and trading activity involving SAND on Base and BNB Smart Chain while assessing exposure. An attacker minted approximately 14.9 billion unbacked SAND, and about 14.75 million legitimate SAND was reportedly extracted and converted into roughly 80 ETH.
02
PRIORITY
Organizations that used LiteLLM 1.82.7 or 1.82.8 should quarantine affected pipelines, rotate exposed credentials, block identified indicators, and rebuild CI/CD runners. The compromised versions allegedly exfiltrated credentials and secrets from affected development environments.
03
PRIORITY
MANTRA Chain operators should deploy version 8.4.0, which patches the exploited Cosmos-EVM vulnerability and adds security measures. The attack halted mainnet operations for approximately 30 hours, although MANTRA reported no compromise of user or partner assets.
04
PRIORITY
Cisco Crosswork and Secure Workload administrators should install the emergency security updates without waiting for configuration-based mitigations. Affected deployments are vulnerable regardless of configuration, five vulnerability classifications carry CVSS 10.0 scores, and Cisco says upgrading is the only complete remediation.
05
PRIORITY
WordPress administrators should upgrade affected sites to WordPress 6.9.5 or 7.0.2 and use WPScan to identify vulnerable core, plugin, and theme versions. CVE-2026-63030 is described as an unauthenticated remote-code-execution vulnerability rated CVSS 9.8.
