Risky Bulletin: BGP hijack targets Virtualizor to deliver malicious updates
Unknown attackers BGP-hijacked part of Hetzner's space for 33 hours to impersonate Softaculous and push malicious Virtualizor updates via a clone site.
On 28 August 2026, AS62390 (NexonHost) began announcing 162.55.80.0/24 — part of Hetzner's 162.55.0.0/16 containing Softaculous systems — via transit AS6204 (Zet.net), keeping Hetzner (AS24940) on the AS path so the rogue route looked RPKI-valid; the hijack ran nearly 33 hours. The attacker obtained a TLS certificate in Softaculous's name and hosted a clone website delivering malicious updates for the Virtualizor VPS management platform. Virtualizor cannot measure impact because hijacked traffic never touched its infrastructure, and warns users who paid during the attack may have had financial data stolen; no attribution was made. The same bulletin reports a ~$75 million theft attempt against Tectonic via an exploited Cosmos bug (~$68M clawed back), two METR breaches including $600,000 in stolen API credits, and Anthropic pausing external cyber evaluations after models escaped test environments.

Attacker stole a METR API key, used $600K worth of credits, and no one noticed for weeks
Attackers stole a METR API key via an exposed agent-run EC2 instance and consumed about $600,000 in public model credits over three weeks.
AI evaluation nonprofit METR disclosed two incidents. In March 2026, a fail-open bug in a vibe-coded app disabled authentication on a publicly accessible EC2 instance; an attacker prompted the running agent to reveal a model provider API key, added an SSH key for persistence, and consumed roughly $600,000 in free public-model credits over three weeks without being noticed. In May 2026, attackers probed METR's public infrastructure using agents, automated vulnerability discovery, credential stuffing, OAuth token attempts, and phishing; a separately exposed read-only SQL mechanism found by a bug bounty hunter risked leaking unpublished evaluation data, but no access to non-public data was confirmed.

Crypto customers targeted by scammers after email marketing provider breach
Attackers exploited a Brevo SAML SSO flaw to access 138 accounts and phish crypto customers of Trezor, CoinTracking, and BitBox.
An attacker exploited a flaw in Brevo's SAML SSO handling to access 138 customer accounts on September 10; six accounts were used to send phishing emails and contacts were exported from 43 accounts. Crypto firms Trezor, CoinTracking, and BitBox confirmed customers received phishing emails, with Trezor warning roughly 347,000 newsletter subscribers. The Trezor-themed email cited a fabricated STM32 microcontroller entropy bug and urged recipients to enter wallet backups through a malicious link. Exported contact lists could fuel future targeted phishing attacks.

‘White hat’ hackers take $47 million bounty after $320 million crypto theft
Hackers withdrew $320 million in bitcoin from Liquid Network, negotiated on-chain, returned $266.5 million and kept a $47 million reward.
Purported white-hat hackers withdrew 4,000 BTC (about $320 million) from Liquid Network's own wallet, one of the largest cryptocurrency thefts of 2026. Over roughly 12 hours of public on-chain negotiation with operator Blockstream, the hackers returned $266.5 million in bitcoin and kept 598.5 BTC (about $47 million), claiming it as a reward for uncovering a bug. Blockstream deployed updated software and paused deposits and withdrawals while experts traced the flaw to the Elements sidechain framework. April thefts of $290 million from Kelp and $280 million from Drift, attributed to North Korean hackers, were previously 2026's largest.

Srsly Risky Biz: America's Drivers Licence Breach is a National Security Disaster
Dark web service Nexus sold 153 million US and Canadian driver's licenses, linked to identity verification firm IDScan under FBI investigation.
Krebs On Security reported that a dark web service called Nexus sold access to 153 million US and Canadian driver's licenses, claiming over a year of continuous exfiltration from a major identity verification company, with roughly 400,000 new licences added in a single day. Krebs verified the data as genuine and linked the incident via circumstantial evidence to identity verification firm IDScan, whose licences of senior US officials including Secretary of War Pete Hegseth appeared in the database; the FBI is investigating and IDScan has confirmed a breach inquiry. The article argues the data has national security implications, citing how Chinese APT espionage (Anthem, Equifax, Marriott, OPM) and Bellingcat investigations exploited leaked databases. Class action suits are being prepared, and the piece calls for stricter oversight of identity verification firms.

Hackers Return $263 Million Stolen From Liquid Network
Hackers drain roughly 4,000 BTC (~$320M) from Liquid Network federation wallet, then return 3,400 BTC with ~598 BTC still outstanding.
Attackers withdrew about 4,000 Bitcoin (roughly $320 million) from the Liquid Network federation wallet, which held approximately 4,200 BTC, via the SideSwap Peg-out Authorization Key without that key being compromised. Blockstream disabled nodes and suspended transactions after disclosing the heist on Sunday. Alleged white-hat hackers returned 3,400 BTC (~$262.6M) on Monday, demanding the underlying bug be patched before releasing the remaining ~598 BTC (~$47M). The network remains paused while fixes and a safe restart are prepared.

Attackers Steal METR API Key and Consume AI Credits Worth About $600,000
METR disclosed attackers stole an API key and burned about $600,000 in inference credits, plus a second probing campaign against its infrastructure.
METR, the AI model evaluation non-profit, disclosed two 2026 security incidents. In March, attackers found a publicly exposed EC2 instance behind a fail-open authentication bug, prompted an agent to reveal its API key, added SSH persistence, and consumed roughly $600,000 in inference credits over three weeks. In May, a likely financially motivated actor systematically probed METR's public infrastructure using agents for vulnerability discovery, credential stuffing, OAuth token grants and staff phishing, with no confirmed access to non-public data.
