ICT Security-Sécurité PC et Internet

According to the notice posted by T-Mobile on its website, the suspicious activity took place this Monday. Hackers managed to breach a database by exploiting a vulnerable API -- or application programming interface, which is a set of software building blocks that make it easier for developers to access data or technologies when creating an app.

T-Mobile cyber security staff detected the attack a short time after it began. In a statement to Motherboard, a T-Mobile spokesperson said that "less than 3%" of the company's roughly 76 million subscribers was accessed. Limiting the damage to such a small percentage is certainly a positive... but it still means that roughly 2 million T-Mobile customers were impacted.


The company's announcement states that customers' names, billing zip codes, phone numbers, email addresses and account numbers may have been exposed. The particular API that the hackers exploited was not, however, wired in to any payment card data. Social security numbers and passwords were also not accessible via the API.

Sportswear maker Adidas announced a data breach yesterday evening, which the company says it impacted shoppers who used its US website.

The company says it became aware of the breach on Tuesday, June 26, when it learned that an unauthorized party was claiming to have acquired the details of Adidas customers.

"According to the preliminary investigation, the limited data includes contact information, usernames and encrypted passwords," an Adidas spokesperson said.

"Adidas has no reason to believe that any credit card or fitness information of those consumers was impacted," he added.

The company said it's still investigating the breach with law enforcement and security firms.

A few millions impacted

A previously undisclosed flaw in Nike's website allowed anyone with a few lines of code to read server data like passwords, which could have provided greater access to the company's private systems.

An 18-year-old researcher Corben Leo discovered the flaw late last year and contacted Nike through the company's dedicated email address for reporting security flaws, which it advertises on its bug bounty page.

After hearing nothing back for more than three months, Leo contacted ZDNet, which also alerted the company to the vulnerability.

The bug exploited an out-of-band XML external entities (OOB-XXE) flaw that abused how Nike's website parses XML-based files, allowing the researcher to read files directly on the server. OOB-XXE flaws are widely seen as esoteric and difficult to carry out, but can be used to gain deep access to a server's internals.

Gaining access to a server's files can disclose other avenues for exploitation, such as remote code execution or pivoting to other connected servers or databases.

Have you watched a YouTube video lately in a country where English is widely used?

If so, we’re willing to bet that you’ve seen an advert for Grammarly, an online spelling and grammar checker.

In fact, we’ll suggest you’ve seen the Grammarly ad many times, perhaps even very many times – we certainly have.

The ads seem to be working, with the product currently closing in on 1,000,000 installs in Firefox, and already claiming more than 10,000,000 in Chrome.

As the product pitch in the Firefox add-on store explains:

Once you register your new account, you will start to receive weekly emails with personalized insights and performance stats (one of our most popular new features). Working on a large project, an essay, or a blog post? No sweat. You can create and store all of your documents in your new online editor.

In other words, your Grammarly account ends up knowing a lot about you, and holding copies of a lot of what you’ve written.

A security hole in Grammarly could therefore tell crooks much more about you than you’d like them to know.

So praktisch SaaS ist. Das Konzept birgt auch große Risiken, wenn wie jetzt etwa Typeform ein SaaS-Provider das Opfer eines Datendiebstahls wird. Dann sind meist auch die Kunden des Anbieters betroffen.

Viele Unternehmen binden heutzutage immer wieder diverse Online-Umfragen in ihre Web-Seiten ein. Dabei greifen sie gerne auf vorgenerierte Formulare von externen Anbietern zu. Eines dieser Unternehmen, der spanische Software-as-a-Service-Spezialist (SaaS) Typeform, musste nun einen Datendiebstahl eingestehen, bei dem auch zahlreiche Datensätze von Kunden des Unternehmens geklaut worden sein sollen.

Der oder die Angreifer konnten sich laut Typeform Zugriff auf ein Backup von Anfang Mai dieses Jahres verschaffen. Darin enthalten waren API-Keys, Token zum Zugriff auf die von Typeform angebotenen Dienste und Zugangsdaten zu OAuth-Applikationen, aber auch Daten von Kunden, die Online-Formulare ausgefüllt hatten. Um welche Informationen es sich dabei genau handelte, teilte Typeform nicht mit. Laut Medienberichten meldeten sich aber bereits mehrere betroffene Unternehmen wie Fortnum & Mason.

Wie das Londoner Kaufhaus mitteilte, wurden ihm etwa 23.000 Datensätze gestohlen. Sie enthielten E-Mail-Adressen, Antworten auf Fragen und teilweise auch Postadressen sowie andere private Informationen der Nutzer.

A little-known, Florida-based marketing firm called Exactis may be responsible for a significant amount of personal data being exposed. According to a report from Wired, the firm left 340 million individual records on a publicly accessible server that any person could have gotten ahold of.

The leak was discovered earlier this month by security researcher Vinny Troia, founder of the New York-based security firm Night Lion Security. He reported his find to the FBI and Exactis earlier this week, and while the company has since protected the data, it’s unclear just how long it sat exposed.

So just how bad is the leak? It’s pretty bad! The data stored on the server amounts to about two terabytes worth of personal information.

Troia told Wired the database from Exactis appears to have data from “pretty much every US citizen” in it, with approximately 230 million records on American adults and 110 million records on US business contacts. That falls in line with Exactis’ own claim on its website that it has data on 218 million individuals. If the leak is truly as big as estimated, it would make for one of the largest exposures of personal information in recent memory.

Swiss telecoms giant Swisscom has admitted that it suffered a serious security breach in the autumn of 2017 that saw the theft of contact details of approximately 800,000 customers – most of whom were mobile subscribers.

Data exposed during the breach included:

Customers’ first and last names
Customers’ home addresses
Customers’ dates of birth
Customers’ telephone numbers

Interestingly, in a press release, Swisscom pointed a finger of blame at an unnamed third-party sales partner who had been granted “limited access” to the data in order that they could identify and advise customers approaching contract renewal.

That sales partner, Swisscom says, suffered its own security breach – somehow allowing its access keys to Swisscom to fall into criminal hands.

A routine check of Swisscom’s operational activities uncovered the unauthorised data access, and the offending partner’s access rights revoked.

Grammarly has fixed a security bug in its Chrome extension that inadvertently allowed access to a user's account -- including their private documents and data.

Tavis Ormandy, a security researcher at Google's Project Zero who found the "high severity" vulnerability, said the browser extension exposed authentication tokens to all websites.

That means any website can access a user's documents, history, logs, and other data, the bug report said.

"I'm calling this a high severity bug, because it seems like a pretty severe violation of user expectations," said Ormandy, because "users would not expect that visiting a website gives it permission to access documents or data they've typed into other websites."

In proof-of-concept code, he explained how to trigger the bug in four lines of code.

More than 22 million users have installed the grammar-checking extension.

Ormandy filed his bug report Friday, subject to a 90-day disclosure deadline -- as is the industry standard. Grammarly issued an automatic update Monday to fix the issue.

Ormandy has in recent months examined several vulnerable web browser extensions. Earlier this year, he found a remote code execution flaw in the Cisco WebEx Chrome extension, and a data-stealing bug in the popular LastPass password manager.

A spokesperson for Grammarly did not immediately return a request for comment.
