Poisoned Adform ad script swapped crypto wallet addresses on customer sites

Attackers compromised a widely used tracking script from advertising firm Adform, turning it into a browser-side tool that rewrites cryptocurrency wallet addresses. The malicious code was appended in obfuscated form to Adform's trackpoint-async.js library, served from the company's own infrastructure, so any site loading it ran the altered script in visitors' browsers. It swapped Bitcoin, Ethereum, and Tron addresses both in the clipboard and in form fields, redirecting transfers to the attacker. Adform detected and removed the code on July 27 and says it did not install software or persist after a page closed, but cached copies may linger. It has not said how many page loads were affected.

Check
Warn people who sent cryptocurrency after visiting sites recently to clear their browser cache and verify every wallet address, and review whether your own sites embed third-party scripts that could be poisoned.
Affected
Anyone who copied or entered a crypto wallet address on a site loading Adform's tracking script on July 27; the swapped address silently redirected funds, and cached copies may still be active.
Fix
Limit and monitor third-party scripts, use subresource integrity where possible, isolate payment and wallet pages from ad and tracking code, and treat any shared external script as a single point of compromise.

Russian actor hides Starland malware in fake WebEx, Zoom, and dev-tool installers

Cisco Talos detailed a financially motivated Russian group, tracked as UAT-11795, that spreads a new backdoor called Starland RAT through trojanized installers for legitimate software including WebEx, Zoom, MobaXterm, DBeaver, and FaceIT. Active since at least mid-2025 and mainly hitting US victims, the campaign likely uses fake verification lures to deliver the installers. Once run, the malware sets up persistence, tries to escalate privileges, and detects sandboxes, then steals browser data and more than 40 kinds of cryptocurrency wallets, profiles the machine, and maps Active Directory. It can take screenshots, run shell commands, inject shellcode, and pull down further payloads, giving the operator broad control.

Check
Remind users to download software, especially collaboration and developer tools, only from official vendor sites, and watch for trojanized installers delivered through fake verification pages or paste-into-terminal style lures.
Affected
Users who install trojanized versions of tools like WebEx, Zoom, MobaXterm, or DBeaver; Starland RAT then steals credentials and crypto wallets, maps Active Directory, and gives the attacker persistent machine control.
Fix
Enforce software installation from trusted sources, use application allow-listing, block known indicators, monitor for suspicious HTA and installer activity and Active Directory reconnaissance, and hunt for Starland's persistence and shellcode behaviors.

THORChain drained for ~$10.8M in coordinated multi-chain exploit across BTC, ETH, BNB Chain, and Base

On-chain investigator ZachXBT flagged a coordinated exploit against THORChain's cross-chain liquidity pools on May 15, 2026, with PeckShield confirming losses of approximately $10.8 million across four blockchains - around 36.85 BTC plus $7 million in assets from Ethereum, BNB Chain, and Base. The attacker funneled funds into two main addresses (BTC bc1ql4u94klk265lnfur2ujk9p6uh52f2a8jhf6f37 and ETH 0xd477b69551f49C0519F9B18c55030676138890Bd). THORChain responded with a global emergency halt of trading and signing - a controversial move given the protocol's permissionless positioning. No official post-mortem has been released. The RUNE token dropped 12-14% on the news; the same protocol was previously used by North Korean operators to launder $175 million.

Check
If your organization custodies or trades THORChain liquidity, RUNE, or assets bridged through THORChain in the May 14-15 window, reconcile on-chain balances against the two known exploiter addresses and check for any user funds in affected pools.
Affected
THORChain liquidity providers, aggregators routing through THORChain, custodians holding RUNE, and wallets that bridged BTC, ETH, BNB Chain, or Base assets through the protocol on May 14-15. DeFi exposure is highest for cross-chain aggregator front-ends.
Fix
Block transfers to the two attacker-controlled addresses (BTC bc1ql4u94klk265lnfur2ujk9p6uh52f2a8jhf6f37 and ETH 0xd477b69551f49C0519F9B18c55030676138890Bd), monitor RUNE deposits to centralized exchanges for laundering attempts, and pause front-end integrations with THORChain until a post-mortem and patched release are published.
