Fixes nobody has installed yet

High ↑

PaperCut published its emergency fixes on 28 August. [1] Organisations were still being broken into through those two flaws twelve days later. [1] Attackers are also exploiting a flaw in Super Forms, a WordPress add-on that collects website forms, which has a fixed version waiting. [4]

Break-ins through people, not software

Building ↑

The law firms Greenberg Traurig and Eckert Seamans both say documents left after someone was tricked, not after their systems were broken. [2] Revolut, a British banking app, handed over copies of customer passports after fake requests arrived from a real government email address. [3] A former phone-shop employee in the United States was jailed for 16 months for moving customers' numbers to criminals' SIM cards. [4]

AI doing the attacker's legwork

High ↑

One person used hundreds of AI helpers to break into 395 organisations. [1] Anthropic says Russia-linked spies used its Claude model to change their tools whenever security products flagged them. [5] Anthropic's report describes misuse across seven kinds of harm. [12]

Rules arriving after the harm

Building ↑

The UK government gave Apple and Google three months to block images of child nudity on phones. [8] That deadline passed on Tuesday and the UK government is now writing a law instead. [8] Researchers found more than 250 further child-abuse advertisements on Meta's platforms since the start of August. [7]

One person's AI helpers broke into 395 organisations. Two hundred of them were schools.

One person broke into at least 395 organisations in 48 countries using hundreds of automatic AI helpers. [1]

the attacker also left some victims alone for days before going further [1]

the fixes went out on 28 August and GreyNoise reported on Wednesday [1]

Who is involved

Who is involved

Why it matters

Watch whether these break-ins turn into ransom demands; GreyNoise says the access may be passed to extortion crews. [1]

What's really going on

One person broke into 395 organisations this week by making copies of an automatic helper.

What's really going on

Every victim was a machine whose owner had not installed a fix published on 28 August.

Who gains

Copies of a helper did the work, so one person now holds access to at least 440 servers that can be sold on. [1]

Who gains

GreyNoise says the access may be handed to affiliates or data-theft groups, who would then not have to find a way in themselves. [1]

Who pays

They run PaperCut on their own servers, so installing the 28 August fix was their job, and break-ins were still landing twelve days later. [1]

Nobody knows yet

What the 395 break-ins are for.

GreyNoise says the attacker left many victims untouched for days and may hand the access on, and no ransom demand has been reported. [1]

Nobody knows yet

Who the attacker is.

GreyNoise infers a Russian speaker only from the list of 28 countries the helpers were told to skip, and no authority has named anyone. [1]

Good news

In at least one of the 395 attacks, Cloudflare's web firewall blocked the attacker before the attack reached the server. PaperCut replaced its emergency fixes with full releases on Thursday.

The whole story, in 12 parts ↓

Part 1 of 12 · Who else is involved

Part 1 of 12 · Who else is involved

Part 2 of 12

Schools and colleges were 204 of the victims.

Part 2 of 12

The United States had 98 and the United Kingdom 59. [1]

Part 3 of 12

The way in was two flaws in PaperCut, printing software that schools, councils and companies run on their own servers. [1]

Part 4 of 12

PaperCut published emergency fixes for both on 28 August, the day after a school-sector customer reported a break-in. [1]

Part 5 of 12

The attacker was not fast at any one break-in.

Part 5 of 12

The helpers ran the same attack side by side, and 11 organisations were compromised in 26 seconds. [1]

Part 6 of 12

At one American high school, the attacker went from first access to full control of the school's accounts in seven minutes. [1]

Part 7 of 12

GreyNoise, the threat-tracking firm that traced the campaign, says the attacker went from an empty workspace to a first real break-in in under four hours. [1]

Part 8 of 12

The person running the helpers told them to skip 28 countries, led by Russia, China, Hong Kong, Thailand and Iran.

Part 8 of 12

Some helpers attacked organisations in those countries anyway. [1]

Part 9 of 12

That skip list is the one criminal crews normally use, which is why GreyNoise thinks the person is likely Russian-speaking. [1]

Part 10 of 12

Nobody knows what the access is for.

Part 10 of 12

Many victims were left untouched for days, and GreyNoise says the access may be handed on to other crews. [1]

Part 11 of 12

In at least one case, Cloudflare's web firewall, which filters traffic before it reaches a server, blocked the attacker. [1]

Part 12 of 12

PaperCut replaced the emergency fixes with full maintenance releases on Thursday. [1]

Law firms robbed through their own lawyers

Swipe up for the story ↑Scroll down for the story ↓

Greenberg Traurig, a US law firm with more than 3,200 lawyers, said on Thursday that an outsider reached a limited number of documents and posted them on the dark web. [2]

It told the state of Vermont that Social Security information was exposed, while insisting its own systems were never broken into. [2]

Eckert Seamans, a Pittsburgh firm, faces two proposed class actions after disclosing that one of its lawyers was tricked into granting access in August. [2]

The law firm BakerHostetler counted nearly 60 law-firm incidents last year, almost double the year before. [2]

Why it matters

Law firms hold other companies' deals, lawsuits and investigations, so one trick reaches clients who never chose the firm's security.

Why it matters

Quinn Emanuel, McDermott Will and Schulte, Herbert Smith Freehills Kramer and Goodwin Procter have all disclosed breaches in recent weeks. [2]

Why it works on people

Saying that a firm's own systems were never broken into is a statement about equipment, and it is heard as a statement about whether anybody's documents left. [2][3]

Who pays

Social Security information and dates of birth were exposed by firms they hired for legal work, not for holding data. [2]

Nobody knows yet

How the Eckert Seamans lawyer was tricked.

The firm has said only that a lawyer was the target of a social engineering attack in August, and it did not answer questions. [2]

Revolut sends passports to fake officials

Swipe up for the story ↑Scroll down for the story ↓

Revolut, a British banking app with no branches, confirmed on Saturday that customer information went to an outsider who sent fraudulent requests. [3]

The requests were sent from the email domain of a real government agency. [3] A message from a government domain is normally taken as official. [3]

The data included dates of birth, postal and email addresses, phone numbers, and copies of passports and driving licences. [3]

Revolut says it blocked the address, alerted the agency, law enforcement and the regulators, and that accounts and money are untouched. [3]

Why it matters

A passport copy cannot be changed the way a password can, so the people affected carry this for years, and Revolut has not said how many there are. [3]

Why it matters

The company is preparing a public share listing at a valuation of up to $200 billion. [3]

What's really going on

The week's other two big data losses needed no flaw at all: a lawyer at Eckert Seamans was tricked into granting access, and Revolut answered fake requests sent from a real government email address.

Who pays

A passport scan cannot be changed after it leaks, and Revolut has not said how many people it sent. [3]

Nobody knows yet

How many Revolut customers lost identity documents.

Revolut gave no number, and the list of what was taken comes from a TechCrunch report rather than from the company. [3]

Claude used for weapons work, Anthropic says

Swipe up for the story ↑Scroll down for the story ↓

Anthropic, the American maker of the Claude AI models, published a report on Thursday on how people misused them. [6]

It says a China-based user built software to rank air-defence targets and model radar jamming, with one simulation holding 12 targets in Taiwan. [6]

A group in northern Yemen used Claude to help write software for a guided rocket and a planned longer-range missile. [6]

Russia-based users worked on control software for swarms of small attack drones. [6]

Anthropic banned the accounts behind the Taiwan work and says it has no evidence the Yemen group fielded a weapon. [6]

Why it matters

China's foreign ministry said it was unaware of the report and opposes smears against the country. [6]

Why it matters

Every part of this account is the company's own, and nobody outside it has seen the accounts. [6]

Nobody knows yet

Whether any weapon in Anthropic's report was ever built.

Anthropic says of the Yemen group that it has no evidence a weapon was fielded and that its safeguards blocked many requests but not all, and nobody outside the company has examined the accounts. [6]

Russian spies used AI to dodge detection

Swipe up for the story ↑Scroll down for the story ↓

Anthropic says a Russia-linked spying group used Claude against more than 20 government, intelligence, diplomatic and defence bodies. [5]

Its methods match Midnight Blizzard, a group Western agencies attribute to Russia's foreign intelligence service. [5]

It got into the mailboxes of two drone-parts makers, then targeted a military drone maker and took a complete software kit for its vision system, which it used Claude to pick apart. [5]

Anthropic says most operations it disrupted were run by AI, with humans as overseers. [11] When security products flagged its tools, it used Claude to change them and put them back. [5]

Why it matters

Anthropic's own conclusion is that this pushes the cost back onto defenders, because a new detection used to slow an attacker down and can now be bypassed faster than defenders ship the next one. [5]

Why it matters

It also published technical fingerprints so other security teams can search their own records. [5]

How it works

Attacks copy themselves. Repairs are installed by hand.

How it works

One attacker set hundreds of automatic helpers on a flaw that was fixed twelve days earlier, and every organisation that had not installed the fix was found within minutes.

How it works · step 1 of 5

A flaw is found and a fix is published

How it works · step 2 of 5

The fix has to be installed, machine by machine, by whoever owns each one

How it works · step 3 of 5

The attacker writes one working attack, then makes copies of a helper that runs it

How it works · step 4 of 5

Each copy costs almost nothing, so every machine still missing the fix is reached at once

How it works · step 5 of 5

The owners' side of the work takes as long as it always did

The twist

The attacker did not get better at breaking in.

The twist

He got faster at doing the same break-in four hundred times, and the people installing the fix work at the speed they always worked at.

Seen the same day

the same step repeats: the attacker's side of the loop is now automatic, while a new detection still has to be written and shipped by people

Seen the same day

2.37 million messages a day were generated, and the filter that would catch them is updated by hand

Seen the same day

the adverts were made in bulk by software, and the review that was supposed to stop them is the slow, human part

Seen the same day

the fixed version exists and is being attacked anyway, because each site owner installs it separately

The catch

Speed only helps an attacker where a fix exists and has not been installed.

The catch

The law-firm break-ins and the Revolut requests needed no flaw at all, so nothing about them would have been slower.

The whole

Each of those 204 schools has one or two people who do the updating, alongside everything else they do.

The whole

Almost every machine any of us rely on is patched by somebody in that position, and none of them is told which flaw is being copied this week.

Who gains

Anthropic published technical fingerprints of the Russia-linked campaign, so anyone can search their own records for it. [5]

Good news

Anthropic published the technical fingerprints of the Russia-linked campaign, so any security team can search its own records for the same activity.

Meta ran hundreds more child-abuse adverts

Swipe up for the story ↑Scroll down for the story ↓

Researchers at the Tech Transparency Project found more than 250 further advertisements containing child sexual abuse material on Facebook, Instagram and Threads since the start of August. [7]

Meta had removed about 50 such adverts a month earlier and said new AI tools would catch them. [7]

Some of the new ones used photographs of real children, including one taken from a European royal family's official website. [7] Many led to apps that undress people in pictures. [7]

All were reported to the US centre that collects child-abuse reports. [7]

Why it matters

Meta's own rules say every advert is reviewed before it runs, and these ran anyway. [7]

Why it matters

The researchers say that in some cases Meta took a week to act on an advert they had reported while it was live. [7]

How it works

the adverts were made in bulk by software, and the review that was supposed to stop them is the slow, human part

The idea, in story 5: Attacks copy themselves. Repairs are installed by hand. →

Who gains

The abusive advertisements were paid placements, and they ran until researchers reported them. [7]

Who pays

Researchers identified four real minors, including a teenager with a public account on one of Meta's own platforms. [7]

Nobody knows yet

How many abusive advertisements are still running on Meta's platforms.

The figure of more than 350 since late last year is what the researchers found, not a total, and Meta has published no count. [7]

UK writes a law after Apple and Google miss a deadline

Swipe up for the story ↑Scroll down for the story ↓

In June the UK government gave technology companies three months to make taking, viewing or sharing images of child nudity impossible on their devices. [8]

The deadline passed on Tuesday, and the culture secretary, Lisa Nandy, told lawmakers the work done does not meet the scale of the problem. [8]

Under the planned law, companies that do not build the protections into phones and tablets sold in the UK would face fines, and their bosses could face criminal liability. [8]

Apple says it has shared future plans with officials. [8]

Why it matters

The messaging app Signal accused the UK government in June of using child safety to rush surveillance powers into law. [8]

Why it matters

Nandy says she will reassess the legislation if the companies ship something while it is being drafted. [8]

Who gains

Three months passed with nothing shipped, and the UK government's answer is a law that still has to be written and passed. [8]

Nobody knows yet

Whether Apple and Google will build the child-nudity blocking without a law.

The UK culture secretary says she will reassess the legislation if they do, and neither company has said what it will ship or when. [8]

Huawei goes on trial in New York

Swipe up for the story ↑Scroll down for the story ↓

The US criminal trial of Huawei, a very large Chinese telecommunications company, opened in a Brooklyn federal court on Wednesday. [9]

A Justice Department lawyer told jurors the company stole trade secrets from five American firms, including router software from Cisco and a phone-testing robot arm from T-Mobile. [9]

Huawei's lawyer said the case is about competition rather than conspiracy, and that prosecutors are cherry-picking isolated events. [9]

The case began with a 2018 indictment over sanctions and bank fraud, and is expected to last three months. [9]

Why it matters

The charges include racketeering, which treats the alleged thefts as one long business practice rather than separate incidents by individual staff. [9]

Invisible characters slip phishing past filters

Swipe up for the story ↑Scroll down for the story ↓

Microsoft says attackers hid invisible characters inside ordinary words, such as funding, in phishing emails. [4]

A filter reads a word that is not the word the person sees, so mail trained to spot money scams does not match. [4]

The campaign ran from February to June and sent as many as 2.37 million messages a day. [4] The same trick is used to smuggle hidden instructions into AI systems. [4]

Why it matters

Microsoft says the trick can disrupt filters that learn from patterns in past mail. [4]

How it works

2.37 million messages a day were generated, and the filter that would catch them is updated by hand

The idea, in story 5: Attacks copy themselves. Repairs are installed by hand. →

Phone-shop worker jailed for SIM swaps

Swipe up for the story ↑Scroll down for the story ↓

Kenneth Carter, a former AT&T employee in the United States, was sentenced to 16 months in prison for moving customers' phone numbers onto criminals' SIM cards. [4]

A SIM swap moves a phone number onto a new card, so texts sent to that number reach whoever holds the new card.

The criminals used that to take over bank accounts. [4] Three victims faced intended losses of nearly $600,000. [4]

Carter was typically paid $1,000 to $2,000 for each swap. [4]

Why it matters

Carter abused his role at a phone store, which is the place a number gets moved to a new card. [4]

Who gains

They paid $1,000 to $2,000 a time for account takeovers that no software flaw would have given them. [4]

Who pays

Three faced intended losses of nearly $600,000 after their phone numbers were moved onto cards the criminals held. [4]

Good news

Kenneth Carter, who moved customers' phone numbers onto criminals' SIM cards for $1,000 to $2,000 a time, was sentenced to 16 months in a US prison.

Water plant controllers sit outside every scan

Swipe up for the story ↑Scroll down for the story ↓

Intruders reached water and wastewater treatment equipment across the United States in July, and the US cyber-defence agency counted more than 100 compromised systems. [10]

Most of that equipment was reachable over public mobile networks rather than the city's own network, so no city asset list or network scan included it. [10]

A pump station in Clayton County, Georgia failed at about 1am on 27 July, and the boil-water notice was lifted the next day. [10]

Waco's former chief information officer wrote that those mobile links appear nowhere except the phone bill. [10]

Why it matters

He argues that in a typical city nobody is accountable for the whole shared network, and that the plant answers to public works rather than to an IT department. [10]

Why it matters

He now advises a company selling the technology he bought while he ran the city's systems, and the article says so. [10]

Who pays

A pump station failed at about 1am on 27 July and a boil-water notice ran until the next day. [10]

Nobody knows yet

Who broke into the US water systems in July.

No federal agency has attributed those incidents to anyone, and the advisory that names Iranian-linked actors covers a separate set of intrusions. [10]

FBI warns of permission scams that need no password

Swipe up for the story ↑Scroll down for the story ↓

The FBI, the United States' federal police force, warned that attackers are getting lasting access to accounts without stealing a password. [4]

They impersonate someone the target trusts and send them to an app that asks permission to read their email and files. [4]

The permissions look normal because real apps ask for the same ones. [4] The FBI calls the access persistent, meaning it keeps working after the first sign-in. [4]

Why it matters

The FBI says no password is stolen in this, so the account's own password was never the thing protecting it. [4]

WordPress add-on flaw under attack

Swipe up for the story ↑Scroll down for the story ↓

Attackers are exploiting a flaw in Super Forms, an add-on that collects contact and order forms on WordPress websites. [4]

The flaw lets a stranger with no account upload a file to the site. [4] That can hand over control of the whole website. [4]

A fixed version, 6.3.314, is available, and whoever runs the site has to install it. [4]

Why it matters

The advice is to update to 6.3.314, and until each site's owner does that, the site stays open to it. [4]

How it works

the fixed version exists and is being attacked anyway, because each site owner installs it separately

The idea, in story 5: Attacks copy themselves. Repairs are installed by hand. →

Devices made to leak sound by radio

Swipe up for the story ↑Scroll down for the story ↓

Researchers demonstrated an attack they call InjectEave, in which a radio signal aimed at an ordinary device makes its electronics leak information. [4]

They tested 11 commercial products, including headphones, office phones, smart fans and lamps. [4]

They recovered private audio in some cases, and in others could tell whether an appliance was switched on. [4] Nothing had to be touched or modified. [4]

Why it matters

The researchers showed it in tests on their own equipment, and it describes a way in that no software update would close. [4]

That's the whole Cyber day.
