Hackers linked to Russia's spy service poisoned websites to reach phones that had missed updates
Swipe up for the story ↑Scroll down for the story ↓
Hackers hid code on real and fake websites to break into iPhones and Android phones that visited.
Mid-October
Sekoia finds the campaign
4 November
Sekoia publishes
Sekoia, a French security firm, found the campaign in mid-October.
APT29
hacking group tied to Russia's foreign spies
Sekoia
the firm that made the link
Sekoia ties it, with moderate to high confidence, to a hacking group called APT29.
The attacks worked only on phones that had missed updates.
The attackers used 8 known flaws across iPhones and Android phones.
Who is involved
Plerdy
a Ukrainian tool that tracks website visits; its script was tampered with for a week
Who is involved
Apple and Google
the makers of iPhone and Android software; both had already fixed every flaw used
Why it matters
Drone-equipment sites
Army sites
Sekoia says several sites are likely to draw important visitors in the war between Russia and Ukraine.
Why it matters
A 2024 APT29 campaign on Mongolian government sites took cookies only for chosen websites.
How it works
Threat analysts call this a watering hole attack: the hackers poisoned websites and waited for visitors' phones to arrive.
How it works
The hidden code reads each phone's software version, so the server picks an attack that still works on it.
Seen it before
A pickpocket waits at the busy station everyone passes through, rather than knocking on each door.
The truth
The link to Russia rests on similar past attacks and overlapping online systems, Sekoia says.
Good news
Sekoia says a phone running up-to-date software is safe from these attacks.
What comes next
US federal agencies have until 18 November to patch that flaw.
Who gains
State hacking groups such as APT29
Sekoia says packaged kits cut the cost and skill needed, so state hackers now reuse them.
Nobody knows yet
How many phones the Russian-linked attackers actually broke into.
Sekoia did not say how many devices were compromised.
Nobody knows yet
Whether the attackers wanted particular people or anyone at all.
Sekoia says it remains unclear whether they aimed at visitors to certain sites or took from as many old phones as they could.

Part 1 of 5 · Who else is involved
CISA
the US cyber-defence agency; it listed one of the flaws as under attack
Part 2 of 5
The attackers used 3 routes to reach visitors.
Part 2 of 5
Ukrainian gas producer
US chemical trade group
First, they put code into real websites, including a Ukrainian gas producer and a US chemical trade group.
Part 2 of 5
Second, they built fake copies that passed along the real pages with code added.

27 August
Plerdy's script is tampered with
3 September
the tampering ends
Third, they tampered with Plerdy, a Ukrainian tool that tracks website visits, from 27 August to 3 September.
Part 2 of 5
That week exposed hundreds of those websites and their visitors to the attacks, Sekoia said.
Part 3 of 5
The hidden code first read each visitor's browser and device.

French bank loses about $133 million to hackers
Swipe up for the story ↑Scroll down for the story ↓
Credit Mutuel Arkea, a big French banking group, confirmed on 4 November that hackers took money from it.
Who is involved
ZachXBT
traces crypto, under a false name
That investigator, ZachXBT, works under a false name and first reported the theft on Monday.
“validate the order of magnitude”
The bank would not confirm the figure, but said it could "validate the order of magnitude".
The hackers went through the platform of a service provider, which the bank has not named.
They then used the bank's own account to send money to other banks.
Why it matters
The bank says customer accounts were not reached and customers' money is safe.
How it works
Risk managers call this third-party risk: Credit Mutuel Arkea's attackers came through a supplier, not the bank's front door.
How it works
The supplier's platform could reach the bank, so taking over that platform carried the attackers inside, the bank says.
Seen it before
Someone holding the office cleaner's keys walks straight past the front desk.
The truth
ZachXBT says the attack ran over several days.
The truth
The bank also disputes French press reports that the way in was Fortuneo, its online bank.
Good news
Some of the converted money has been frozen, and the bank is working to recover the rest.
Why it works on people
Credit Mutuel Arkea says its systems spotted the attack very quickly, and that is reassuring to hear, but the bank gave no dates that would let anyone check it.
Nobody knows yet
How much Credit Mutuel Arkea really lost, and through which supplier.
The bank says the final loss is not established, and it has not named the supplier.

Hackers set French blood stores to heat up
Swipe up for the story ↑Scroll down for the story ↓
3 of 3
blood service sites hit
Hackers changed settings on cold rooms at 3 sites of France's national blood service on 2 November.
The rooms normally sit at minus 30C, and the setting reportedly went to 110C.
The rooms hold frozen plasma for transfusions and blood samples.
Who is involved
Coolworld
rents out cold rooms
Coolworld, a Dutch fridge rental firm, confirmed an incident with its remote monitoring software.
Shop fridges were also hit this week, in 8 European countries by one count and 10 by another.
Why it matters
Coop in Sweden has also cut its 7 hit shops' fridges off from the internet.
Why it matters
Ahold Delhaize, a Dutch supermarket group, expects October's attack to cut quarterly sales by up to 250 million euros.
How it works
3 of 3
firms running fake fridges
Security researchers call a decoy system a honeypot: 3 firms set up fake fridge software to watch these hackers.
How it works
Decoys run by Lupovis, a Scottish firm, saw probing 10 days before the second wave.
Seen it before
A shop leaves a marked wallet on a table to learn who picks it up.
The truth
Russian hacktivist groups say they hacked Danfoss, a fridge-control maker.
The truth
Coolworld's statement, as reported, names neither the part nor the supplier it says was at fault.
How it works
Why the days an intruder stays decide how many people get hurt
How it works
Incident responders call it dwell time: the longer an intruder stays unseen, the more people pass through what they can reach.
How it works · step 1 of 5
An intruder gets in, and nothing breaks that anyone can see
How it works · step 2 of 5
Ordinary work carries on, so people keep logging in and booking
How it works · step 3 of 5
Each new person adds their details to what the intruder can read
How it works · step 4 of 5
The number of people hurt keeps growing until someone notices
How it works · step 5 of 5
Responders count back to the first day, and the total jumps
The twist
Two attacks can use the same way in. The one that stays longer reaches more people, because new customers keep arriving while it is there.
The picture
How long each intruder had access, rounded to the nearest month or week. Plerdy lasted a week and Amadeus just over 3 years, from dates in the stories above.
Seen the same day
On Japan Airlines' dates, new bookings kept entering the system from August 2023 to September 2026, so every passenger in those years joined what could be read.
Seen the same day
Only people who logged in to the file manager during those months lost a password, so each week added more of them.
Seen the same day
Every player who opened the launcher after 27 September ran the changed files, a researcher says, so each new launch could add a victim.
Seen the same day
A break-in through a supplier was caught in one night, when a technician saw the temperature rise, and no blood was lost.
The catch
Dwell time is known only after the fact, and it counts from the first sign found, so the real first day may be earlier.
The catch
A short stay can still do great harm: an investigator says Credit Mutuel Arkea's money went in days.
The whole
If Japan Airlines' dates are right, a passenger who booked a flight in 2025 could not see that someone was already inside the firm their airline had chosen, and the airline could not see it either.
The whole
Most of us sit in systems like this, and we hear about the break-in from a letter that counts backwards.
What's really going on
France's blood service was the opposite case, because a technician saw a fridge temperature rise overnight and no blood was lost.
Nobody knows yet
Who hacked the fridges at France's blood service and in Europe's shops.
No formal blame has been made, and Sekoia's own report points to both Russian and Iranian actors.
Good news
France's blood service lost no blood or plasma after hackers set its cold rooms to heat up. An on-call technician saw the temperature rise overnight, and staff moved the stock.

7 of 7
airlines reporting so far, at least
At least 7 Asian airlines have now reported data thefts traced to Amadeus, a Spanish firm that runs airline bookings.
6 are Japan Airlines, Cathay Pacific, Korean Air, Asiana, Singapore Airlines and Malaysia Airlines.
Japan Airlines counts 92,000 customers, Cathay Pacific 53,000 records and Singapore Airlines 46,000 records.
10 August 2023
Access begins
23 September 2026
Access ends
Japan Airlines says Amadeus told it the access ran from 10 August 2023 to 23 September 2026.
Passports
Emails
Some records held passports, frequent flyer numbers and email addresses.
How it got here
Amadeus serves over 400 airlines and 210 airport operators.
Why it matters
Passengers
new booking numbers, and scam emails
Singapore Airlines will contact people with upcoming flights to change their exposed booking numbers.
The truth
Amadeus told one airline the intruders used login details for a system account.
How it works
On Japan Airlines' dates, new bookings kept entering the system from August 2023 to September 2026, so every passenger in those years joined what could be read.
The idea, in story 3: Why the days an intruder stays decide how many people get hurt →Who pays
Passengers on airlines using Amadeus
Singapore Airlines passengers with upcoming flights must change their exposed booking numbers, and it has told customers to be wary of malicious emails.
Nobody knows yet
How long the intruders were really inside Amadeus.
Japan Airlines says access ran from August 2023 to September 2026, while Cathay Pacific gives those months for the bookings affected.

White House internet addresses up for rent
Swipe up for the story ↑Scroll down for the story ↓
Anyone could rent internet addresses from the White House network for a few dollars, security firm Layer3 Intel found.
Computers or phones of staff there seem to carry proxy software.
Layer3 counted 236 exits through that network between 5 October and 3 November.
26 of 30
days with traffic, out of 30
The traffic used 6 addresses on 26 of 30 days.
Layer3 found 28 separate proxy services could exit through this network.
Who is involved
Synthient
tracks proxy firms
Infatica
proxy bundled with free apps
Synthient, another tracking firm, linked some to Windows 11 computers running Infatica, a proxy often bundled with free apps.
Who is involved
Vladimir Fomenko
founder of Infatica
Infatica's founder is Vladimir Fomenko, a Russian.
Why it matters
Spur, a tracking service, found such software on nearly 300 government networks and 318 utilities in January.
Why it matters
It also found it at 166 healthcare firms and 141 finance firms.
Why it matters
To a website, the traffic looks as if it comes from the White House network, not from the renter.
How it works
Network security calls this a residential proxy: other people's traffic leaves through a real user's device and address.
How it works
App makers can embed proxy code and earn a small sum per install.
Seen it before
A stranger signs your name at the club door, and staff see only your name.
The truth
Layer3 says it found this by chance, without aiming at the White House network.
Who gains
Sellers of residential proxy access
Some resellers charge as little as 60 cents a gigabyte, and buyers can skip identity checks, Synthient's founder says.
Nobody knows yet
Whose devices at the White House were carrying proxy software, and whether anyone misused them.
The tracking firms report the traffic and the software and name no person, and the White House had not replied.

DreamHost intruder stayed about 2 months
Swipe up for the story ↑Scroll down for the story ↓
August
Intruder gets in
23 October
DreamHost finds it
DreamHost, a US web host, says an intruder was inside its web file manager from August until 23 October.
The intruder took upload logins and passwords from anyone who used that file manager in those months.
Some webmail sessions may have been exposed too, DreamHost says.
A spokesperson says well under 10% of customers were hit.
DreamHost says it found no sign of access to control panel logins or card details.
Why it matters
DreamHost is telling those affected to check website files and email forwarding rules.
How it works
Security engineers call this session hijacking: with a stolen DreamHost session, an intruder can act as that user.
How it works
A session token keeps someone logged in after the password check, so stealing it skips that check.
Seen it before
A festival wristband gets you back in without showing your ticket again.
The truth
DreamHost declined to say why it did not detect the attack until last week, citing the investigation.
How it works
Only people who logged in to the file manager during those months lost a password, so each week added more of them.
The idea, in story 3: Why the days an intruder stays decide how many people get hurt →What's really going on
Several of today's breaches were found long after they began: Japan Airlines says the access at Amadeus ran for just over 3 years, and DreamHost's intruder stayed about 2 months.
Who pays
DreamHost's website owners
They are told to check their own website files and email forwarding rules for unauthorised changes.
Nobody knows yet
How many DreamHost customers lost their login details.
DreamHost says only well under 10% of about 400,000, and left BleepingComputer's questions on the count unanswered.

A fix that did not fix Zyxel switches
Swipe up for the story ↑Scroll down for the story ↓
Zyxel, a maker of network gear, has fixed a new flaw in its GS1900 switches, boxes that link computers.
GreyNoise, a firm that watches attacks, counted 996 switches hacked across 48 countries from around 17 August.
Who is involved
Kapibala
suspected Chinese-speaking group
The hackers took device settings and scrambled administrator passwords.
How it got here
At first GreyNoise and CISA, the US cyber-defence agency, blamed an older flaw Zyxel had fixed in June.

Then Binarly, a firm that studies code inside devices, found the hackers' tool in an exposed archive.

Advisory
Zyxel confirmed the new flaw on 11 October and released updates on 22 October.
Why it matters
Switch owners
open until October
Switch owners who installed June's fix were still open to this tool until the October update.
How it works
Software engineers call this an incomplete fix: June's Zyxel update added a check, and the attackers got past it.
How it works
The check trusted a counter that the attackers could change first, so the check passed.

OpenAI's AI writes 948 Linux attacks in a test
Swipe up for the story ↑Scroll down for the story ↓
OpenAI says an upcoming AI model produced 948 working attacks on Linux in a 30-hour run in mid-October.
Each lets someone already on a computer as an ordinary user take full control of it.
The run looked at 2,308 possible flaws and reproduced 1,724 of them.
It cost $1,213,430 in AI credits, or $1,279 per attack.
How it got here
Human researchers review each attack and its fix before reporting it to the Linux maintainers, OpenAI says.
Why it matters
Google's threat team says flaws disclosed each month rose from 5,045 in January to 10,740 in August.
Why it matters
Britain's cyber agency says AI tools have almost certainly led to more unknown flaws being found.
How it works
Security researchers call this exploit development: proving a flaw can really be used, as OpenAI's run did 948 times.
How it works
Each proof cost OpenAI $1,279 in AI credits.

Attack wipes servers at big Russian web host
Swipe up for the story ↑Scroll down for the story ↓
Beget, one of Russia's largest web hosts, says attackers erased data across its cloud services overnight on Sunday.
They got into the systems used to manage its computers, then ran scripts built to erase data.
All binary backups of its rented virtual servers were lost as well.
More than 1,000 servers must be checked by hand before they come back, Beget says.
Who is involved
Beget ranks second among registrars of Russian .RU web addresses, with about 540,700, or 14.7%.
How it got here
The European Union sanctioned Beget this year over services to Russian occupation authorities in Ukraine.
Why it matters
Small online shops
Chestny Znak
product labels
Small and mid-sized firms that host online shops on Beget were mainly affected, the newspaper Kommersant reported.
How it works
Disaster-recovery planners keep an offline backup, one copy no main system can touch; Beget lost all its binary backups.
How it works
Beget's file-level backups survived, and it says nearly all shared websites can likely be recovered.
Seen it before
Keeping the only spare house key inside the house does not help when you are locked out.
The truth
Beget found no sign that attackers copied customer data, but it tells customers to change passwords and keys anyway.
Who gains
Beget
It has told customers the attack may count as force majeure under Russian law, which could excuse it from some contract duties.
Who pays
Small Russian firms hosted on Beget
Their online shops depend on servers that must be checked one at a time, and some virtual server data may not return.
Nobody knows yet
Who wiped Beget's servers and how they got in.
Beget has not said how the attackers entered, citing its investigation, and no group has claimed the attack.

Fake nuclear emails from a hacked Ukrainian paper
Swipe up for the story ↑Scroll down for the story ↓
Hackers got into the website system and newsletter service of the Kyiv Independent, a Ukrainian English-language news outlet.
They emailed false messages to subscribers in Russian and English.
Others made up an attack on Zelensky.
Who is involved
The outlet says it has nearly 3 million monthly readers and over 35,000 paying members.
Members' bank details were safe, it says, because outside services process payments.
How it got here
It came days after hackers sent fake nuclear alerts through Ukraine's air raid app.
Why it matters
“an attempt to sow confusion and erode trust”
The editor, Olga Rudenko, called it "an attempt to sow confusion and erode trust".
How it works
Communication researchers call it source credibility: these hackers used a trusted outlet's newsletter to carry a false claim.
How it works
Subscribers had signed up to that newsletter, so the false email came from a name they already read.

Flaws let one virtual computer take over a Xen host
Swipe up for the story ↑Scroll down for the story ↓
Xen is software that runs many virtual computers on one real machine.
That includes dom0, the virtual computer that manages all the others.
Every Xen version from 4.6 on is affected, the Xen Project said on 3 November.
Who is involved
Anthropic
AI company credited with the find
Xen credits Anthropic, an AI company, with finding the flaws using its Claude model.
Qubes OS, a security-focused desktop system, says every supported setup is affected.
Why it matters
XCP-ng, a platform built on Xen, says a single compromised guest can take over the whole host.
How it works
Isolation
each one keeps to its own memory
Operating-systems courses call this isolation: each virtual computer may touch only its own memory, and Xen checks that.
How it works
To save time on a batch of copies, Xen reused checks it had already made.
Seen it before
A guard checks the first badge in a group and waves the rest through.
The truth
Xen 4.6 to 4.16 are affected, yet the advisory has no patch for them.

Flaw in the tool that installs Linux software
Swipe up for the story ↑Scroll down for the story ↓
A flaw in APT, which installs software on Debian and Ubuntu Linux, lets an attacker swap a checked package.
The attacker's code then runs with full control of the computer.
A bad mirror
A bad proxy
The attacker must be able to change the download traffic, as a bad mirror or proxy could.
It relies on APT retrying failed downloads, which it does by default from Debian 12 and Ubuntu 22.04.
4 November
Notices published
Now
Fixes going out
Debian, Ubuntu and APT's developers all published notices on 4 November.
Why it matters
Ubuntu says systems built on Debian and Ubuntu are affected too, without naming them.
How it works
Security engineers call this a chain of trust: APT checks a package before installing, and everything rests on that check.
How it works
This flaw lets the attacker change a package after APT has checked it, which defeats the check.
Seen it before
A teacher marks a test, and someone swaps the paper before it goes in the file.
The truth
APT's developers call the flaw critical, while Ubuntu rates it high at 7.7 out of 10.
The truth
The notices describe the attack over unencrypted web traffic and do not say whether encrypted sources are safe.

- 1this flaw9.8
Ruby on Rails, a toolkit for building websites, has fixed a flaw rated 9.8 out of 10 for danger.
A stranger who uploads a crafted image can write files on the server, with no login.
Database passwords
Outside logins
Apps that keep uploads on their own disk can also have secret files read, including database passwords and outside logins.
3 of 3
conditions, all needed
An app is hit only if 3 things hold.
Rails says the standard ImageMagick rules shipped by Debian and Ubuntu do not block this.
Rails fixed it in new 8.0 and 8.1 versions.
Why it matters
Stored secrets
Connected systems
Those secrets can open the other systems a site connects to, Dark Reading reports.
How it works
Programmers call this unvalidated input: ImageMagick picks how to read a file from its contents, not its name.
How it works
So a file named like a picture can make the tool run a part that reads and writes other files.
Seen it before
A parcel marked socks holds a note telling the post room to open the other parcels.

“not assume it is the only one”
Rails says one attack route was reported to it, but it does "not assume it is the only one".

A lone hacker used stolen app passwords to sign in to Microsoft cloud accounts at IT service firms.

app logins that worked, out of 45
The hacker tried 45 app logins at about 18 organisations and got into at least 33.
That opened 27 organisations, including customers in energy, government and food.
The hacker then downloaded 81 files and reached about 2,300 mailbox items.
95 of 100
sign-ins made by scripts
About 95% of sign-ins came from scripts, with bursts of 24 sign-ins in 10 seconds.
How it got here
Machine accounts can outnumber people by as many as 144 to 1, Entro Labs found by mid-2025.
Why it matters
IT service firms run systems for many customers, so these stolen logins reached firms in other industries.

Chinese keyboard app used to plant spy tools

Who is involved
ESET
security firm
SlippyNunchucks
the group it named
ESET, a security firm, named the group SlippyNunchucks in research published on 4 November.
The app fetched some settings over an unencrypted connection.
Victims were in Hong Kong, Thailand, Japan, Vietnam, Sri Lanka and Oman.
21 September
Tencent acknowledges it
Late October
New version
Tencent, which owns Sogou, acknowledged the report on 21 September and fixed it in a version released in late October.
Why it matters
ESET says the number and spread of victims first made it suspect a software flaw.
How it works
Network engineers call this DNS hijacking: DNS turns a server's name into an address, here the attackers' address.
How it works
The request was not encrypted, so the app took a wrong server's answer as real.
Seen it before
Someone swaps the sign at a road junction, and drivers follow it to the wrong town.
The truth
ESET says the downloader part still does not check file types or limit where files are saved.
Nobody knows yet
Where the redirect that hijacked the Sogou keyboard app happened.
ESET says it could be routers or an internet provider, and it does not know which.
Good news
Tencent moved the Sogou keyboard's traffic to encrypted connections in a version released in late October, after ESET reported the hijacking.

SonicWall, a maker of network security boxes, has warned of 2 flaws in GMS, its older tool for managing them.
The first lets anyone with network access read internal files, with no login.
The second lets someone with high-level access read or change its database.
SonicWall says no fix will come, because GMS has reached end of life.
Who is involved
Researchers at Pentest-Tools found and reported the flaws.

Abraham Teklu Lemma
US government IT worker, 53
Abraham Teklu Lemma, 53, a US government IT worker, has pleaded guilty to sending classified files to Ethiopia.

Who is involved
National Reconnaissance Office
State Department
Justice Department
He worked for the US National Reconnaissance Office, State Department and Justice Department between 2019 and 2023.
Court papers say he copied from at least 133 intelligence reports without permission to see them.
Prosecutors say he burned files to discs, deleted their secret markings, and walked out with discs in his pocket.
He also deposited more than $66,000 in banks during that time, prosecutors say.
Why it matters
Prosecutors say he sent the files to senior Ethiopian officials through an encrypted app.

NIKKE launcher ran hidden code, a researcher says

The makers of Goddess of Victory: NIKKE say its PC launcher files may have been tampered with.
27 September
4 files changed, the researcher says
4 November
Client update goes out
A researcher called MotherSphere says 4 script files on the publisher's own delivery servers were changed on 27 September.
The researcher says the scripts fetched a remote-access tool whenever a player opened the launcher.
Files and screens
Logins
It could run commands, copy files, take screenshots, and steal game logins and browser data.
Another part could reach crypto wallet recovery phrases, BleepingComputer found.
The researcher says a tampered copy of 1 file was still being served after the update.
Why it matters
The makers issued a client update on 4 November and have since posted steps to check a PC.
How it works
Software security calls this a supply-chain attack: the NIKKE launcher ran whatever its publisher's delivery servers handed it.
How it works
Changing the files at that one source reached every player who opened the launcher afterwards.
Seen it before
Tampering at the bottling plant reaches every shop, without anyone visiting a shop.
The truth
Level Infinite, the publisher, had not answered BleepingComputer about the researcher's findings at publication.

Calendar invites used to steal Google logins

A phishing campaign stole live Google logins from company staff from mid-August, Material Security reports.
Voicemail
Court summons
Missed payment
The messages arrive as Google Calendar invites, often from an organisation the recipient already knows.
Most links point first to Google's own address, so a link checker sees nothing wrong.
A hidden server then sits in front of the real Google sign-in page.
Material says 897 web addresses were taken down in a month.
Why it matters
Drive files
App access
A live session reaches a person's mail and Drive files, and can grant other apps access in their name.
How it works
Security engineers call this a reverse proxy: the attacker's server passes everything between the victim and the real Google.
How it works
The victim approves a real prompt and the operator keeps the logged-in session, so a second check does not help.

Meta pays $1.2 million for Muse AI bugs

Meta has paid about $1.2 million in bug rewards for Muse, its personal AI agent.
Of more than 630 reports since April, 64 were valid.
The top reward, $300,000, went for a flaw found 4 months before launch.
Meta took that service offline, fixed it and stopped treating the local machine as trusted.
Another $90,000 went for a web page that tricked Muse when asked to summarise it.
Why it matters
Accounts
Muse can act in a person's email and accounts, so a tricked agent acts in their name.
How it works
AI security calls that prompt injection: words on a web page got treated as instructions by Muse.

Vercel, a cloud firm that hosts websites and AI agents, is rolling out new protection for logins to its platform.
It ties a login session to one device, using a private key stored in the computer's security chip.
So a stolen session cookie cannot be reused on another device.
