Ten agencies from seven countries named a Beijing contractor they say enables China-linked hacking on 8 October, and the US gave five old flaws from their advisory three-day federal patch deadlines the same day. Citrix replaced its own NetScaler fix within a week, Microsoft shipped 973 of its own CVEs in one release, and Boston Scientific told the SEC it is unlikely to meet its guidance after a cyber outage.

Key takeaway

Attackers came through edge appliances and impersonated people; US three-day deadlines only address the first.

Citrix said on 27 September that attackers had used two NetScaler flaws before any fix existed. On 4 October it replaced those fixes with builds 14.1-73.41 and 13.1-64.28, after a third flaw turned up in attacks.

Boston Scientific told US regulators on 8 September that a 25 August network outage will likely hurt its third-quarter and full-year results. The medical-device maker expects to miss sales and profit targets it set on 29 July.

It named no attacker. Investors learn on 28 October whether hospital orders were lost to rivals or only delayed. 

An unauthorised push notification went out through the ASOS app on 6 October, and the NCSC told every ASOS customer to assume they are affected.

Hackers sent a rogue alert through the ASOS shopping app on 6 October and reached customers' names and contact details. ASOS says a staff member was tricked into handing over a login.

The UK's National Cyber Security Centre (NCSC) told all ASOS customers to assume exposure. Fraudsters can now send fake ASOS messages that use customers' real names.

Microsoft tied at least 13 phishing waves this year to Star Blizzard, a hacking unit of Russia's Federal Security Service (FSB). More than 100 organisations were targeted, mostly in the US and UK.

The emails posed as event invitations from groups such as Chatham House. Malware came only after a target replied, which slipped past email scanners.

Britain, the US and the Netherlands exposed CHOSEN BRICK on 15 September, Windows spyware that Iranian state hackers use against dissidents and journalists. Some targets live in the UK.

Operators befriend people on WhatsApp and Telegram, then send tailored fakes such as medical scan results. Stolen files have surfaced on pro-Iranian leak sites.

N-able released two fixes for its N-central IT management software on 5 and 6 September. The second closed a flaw letting outsiders run code on the server without logging in.

N-able said it had no confirmed attacks. On 8 September America's cyber defence agency listed the flaw as exploited anyway. Outsourced IT firms use N-central to run their clients' computers.

CISA listed two Check Point flaws scoring 9.8 on 22 September, one in VPN negotiation on Spark firewalls and one on management servers.

Sources profile:This story draws on neutral-leaning sources

Check Point, the Israeli firewall maker, had two flaws rated 9.8 out of 10 listed as exploited by US authorities on 22 September. Federal agencies had until 25 September to fix them.

One hit Spark firewalls through data sent while setting up a remote connection from 12 September. The other hit management servers over port 19009, so each needed its own update.

Microsoft's September Patch Tuesday fixed 973 flaws in its own products, the most in any monthly release since January 2025.

Microsoft fixed 973 flaws in its own products on 8 September, its largest monthly release since at least January 2025. The previous high was 571 in July 2026.

Only two were already under attack, both Windows privilege flaws. US agencies got 14 days for those, a sign that size and danger had come apart.

Cisco reached 100 entries on the US list of exploited software flaws on 30 September. It is the second company to get there, after Microsoft with 389.

All four of Cisco's September listings hit security products: a firewall manager, an email gateway, an access-control system and a network controller. Each listing gave federal agencies three days to patch.

Astrana Health, a US healthcare company, told the stock-market regulator on 23 September that a cyber attack was material. Callers posed as staff and faked its main phone number to get in.

Astrana judged it serious because of patient data, not money. CenterPoint Energy, Veradigm and Conduent reported their incidents under a voluntary section instead. 

Ransomware leak-site claims fell 23 per cent in September on ransomware.live's count, with Qilin's collapse the largest single part of the drop.

Sources profile:This story draws on neutral-leaning sources

Ransomware gangs posted 815 victim claims on their leak sites in September, down from 1,060 in August, according to the tracker ransomware.live. The Gentlemen led with 106.

Qilin's claims more than halved to 74. Most of the fall came from that one crew, and late postings could still lift September's total. 

ENISA's threat report analysed 8,257 incidents from 2025 and found only 23.8 per cent of NoName057(16)'s assessed attack claims held up.

Sources profile:This story draws on neutral-leaning sources

The European Union Agency for Cybersecurity (ENISA) studied 8,257 incidents from 2025 in its 22 September threat report. Some 51.3 per cent were floods of junk traffic that knock websites offline.

The pro-Russian group NoName057(16) carried out 48 per cent of politically driven attacks. Independent checks backed only 23.8 per cent of its claims.

Peers want frontier AI developers to report when their models are used to break into regulated networks, ahead of the cyber bill's Lords report stage on 26 October.

Sources profile:This story draws on neutral-leaning sources

Peers have tabled AI amendments to the UK's Cyber Security and Resilience Bill before its Lords report stage on 26 October. One would make leading AI developers report hacks carried out with their models.

Another would let ministers order data centres or large AI systems shut down in an emergency. The Scottish Parliament gave its consent to the bill on 7 October. 

Closing comments

Up for edge appliances, sideways for ransomware volume. NetScaler took five federal listings between 26 August and 4 October, and the 27 September fix was itself replaced, so a further Citrix bulletin would mark a structural failure rather than a run of bad luck. The next fixed decision point is Phase III of BOD 26-04 on 7 December 2026, when its binding remediation timelines apply; before that, Lords report stage on 26 October decides whether AI model makers enter UK incident reporting.

Different Perspectives
CISA
CISA
CISA gave federal agencies three days to fix five flaws from 2015 to 2023 on the day the China advisory named Integrity Technology Group, and set the same clock on 34 of 43 September listings. It treats a named state-linked operation as reason enough to patch old software within the week.
Check Point
Check Point
Check Point updated its advisory on 20 September to say its 9.8-rated VPN certificate flaw had been exploited on Spark firewalls since 12 September, five days after the advisory first appeared, and shipped fixes including R81.20 Take 166. It told customers using only pre-shared-key VPN communities they were not exposed.
ASOS
ASOS
ASOS said an unauthorised party reached names and contact details on third-party platforms after obtaining an employee's credentials by impersonating a trusted contact. It said it does not believe payment cards or account passwords were affected, and is investigating.
LKA Hamburg
LKA Hamburg
Hamburg's State Criminal Police Office led the operation that took the KillSec leak site on 30 September, with ten countries, Europol and Eurojust. Investigators link the group to around 1,000 suspected attacks, at least 70 in Germany, and the seizure blocks access to at least 110 terabytes of victims' data.
ENISA
ENISA
ENISA's 22 September threat report found only 23.8 per cent of NoName057(16)'s assessed claims were confirmed by independent availability checks, though the group produced 48 per cent of ideology-driven activity. The agency's numbers show public administration taking 31.8 per cent of attacks, mostly ideological DDoS.
