An Amazon AWS server believed to contain files on all of California’s registered voters was left exposed this year due to a misconfigured database, according to researchers at the Kromtech Security Center. The database was later stolen by cybercriminals demanding a ransom only payable in bitcoin.

Uber sind bereits vor gut einem Jahr Daten von rund 50 Millionen Fahrgästen gestohlen worden. Der Fahrdienst-Vermittler informierte die Öffentlichkeit aber erst am Dienstag über den Vorfall.

Es gehe um Namen, E-Mail-Adressen und Telefonnummern von Nutzern rund um die Welt, erklärte Uber dem Finanzdienst Bloomberg. Außerdem hätten sich die Angreifer auch Zugriff auf Daten von etwa sieben Millionen Uber-Fahrern verschafft.

Es seien aber keine Kreditkarten-Daten oder Informationen zu Fahrten gestohlen worden, betonte die Firma.

Uber räumte nun ein, dass über die Attacke weder Behörden noch Betroffene informiert worden seien. Stattdessen seien den Hackern 100.000 Dollar (rund 85.000 Euro) bezahlt worden, damit sie die gestohlenen Daten vernichten.

„Nichts davon hätte passieren dürfen“

Uber gehe davon aus, dass die Informationen nicht verwendet worden seien, hieß es. Die Hacker seien durch eine schlecht geschützte Datenbank an die Daten gekommen. Der Uber-Sicherheitschef Joe Sullivan wurde diese Woche entlassen, wie Uber weiter mitteilte.

Uber concealed a hack that affected 57 million customers and drivers, the company has confirmed.

The 2016 breach was hidden by the ride-sharing firm which paid hackers $100,000 (£75,000) to delete the data.
The company's former chief executive Travis Kalanick knew about the breach over a year ago, according to Bloomberg, which first broke the news.

The hackers found 57 million names, email addresses and mobile phone numbers, Uber said.
Within that number, 600,000 drivers had their names and license details exposed. A resource page for those affected has been set up.

Drivers have been offered free credit monitoring protection, but per Uber's statement, affected customers will not be given the same.
"While we have not seen evidence of fraud or misuse tied to the incident, we are monitoring the affected accounts and have flagged them for additional fraud protection," Uber's chief executive Dara Khosrowshahi said.

(Reuters) - Microsoft Corp’s secret internal database for tracking bugs in its own software was broken into by a highly sophisticated hacking group more than four years ago, according to five former employees, in only the second known breach of such a corporate database.

The company did not disclose the extent of the attack to the public or its customers after its discovery in 2013, but the five former employees described it to Reuters in separate interviews. Microsoft declined to discuss the incident.

The database contained descriptions of critical and unfixed vulnerabilities in some of the most widely used software in the world, including the Windows operating system. Spies for governments around the globe and other hackers covet such information because it shows them how to create tools for electronic break-ins.

The Microsoft flaws were fixed likely within months of the hack, according to the former employees. Yet speaking out for the first time, these former employees as well as U.S. officials informed of the breach by Reuters said it alarmed them because the hackers could have used the data at the time to mount attacks elsewhere, spreading their reach into government and corporate networks.

Le cabinet d’audit Deloitte a annoncé avoir été victime d’une attaque informatique ayant visé l’un des serveurs de mails utilisés pour échanger avec ses clients. Plus de 240.000 emails d’employés auraient été potentiellement affectés par l’attaque.

Dans sa communication, la société confirme le piratage annoncé par le Guardian, mais explique que le nombre de victimes est une « fraction » des chiffres avancés dans les médias. Pour l’instant, la portée réelle de l’attaque et le nombre de sociétés touchées restent donc impossibles à déterminer : Deloitte doit sûrement avoir une petite idée, vu que ses équipes enquêtent discrètement sur l’affaire depuis maintenant six mois.

MySpace’s turn

Well, it’s happened again.

This time, the breach is said to come from MySpace, and the number of passwords claimed is an eye-popping 427 million.

Apparently, there are only 360 million users on the list, but some accounts have more than one password listed, for reasons that aren’t explained.

Once again, the passwords allegedly exposed in this breach were simple, unsalted SHA-1 hashes, vulnerable to just the same sort of high-speed try ’em all attack as in the LinkedIn breach of 2012.

According to Leaked Source, lots of passwords have already been cracked, with the top 50 choices so far accounting for more than 6 million passwords, or 1.5% of the total.

Bloomberg reports on what seems to be a security scandal at Uber.

The ride-sharing firm concealed the theft of personal information related to 57 million customers and drivers, and rather than inform the concerned parties "paid hackers $100,000 to delete the data and keep the breach quiet."

The hack which Uber says is said to have happened in October 2016, and included the names, email addresses and phone numbers of 50 million Uber customers across the globe.

Bloomberg has the skinny on how the hack occurred, and it doesn't portray Uber in a good light, being the latest example of careless developers leaving internal login passwords lying around online:

Here’s how the hack went down: Two attackers accessed a private GitHub coding site used by Uber software engineers and then used login credentials they obtained there to access data stored on an Amazon Web Services account that handled computing tasks for the company. From there, the hackers discovered an archive of rider and driver information. Later, they emailed Uber asking for money, according to the company.

Joe Sullivan, Uber's chief security officer (and at one time the main security honcho at Facebook), spearheaded the company's response to the breach alongside one other employee. Both are said to have left their positions at Uber this week.

Uber concealed a massive data breach for more than a year, according to a report by Bloomberg.

Hackers stole names, email addresses, and phone numbers of 57 million Uber riders around the world in a breach dating back to October 2016. Data on more than 7 million drivers was also stolen, including over 600,000 drivers' license records.

Trip records, location data, and social security numbers were not stolen in the breach, the company said.

But instead of alerting users of the breach, the company paid the hackers $100,000 to delete the data and to keep details of the breach quiet.

The company confirmed the breach, in a lengthy statement posted on Tuesday.

"As Uber's CEO, it's my job to set our course for the future, which begins with building a company that every Uber employee, partner and customer can be proud of," said Dara Khosrowshahi. "For that to happen, we have to be honest and transparent as we work to repair our past mistakes."

According to Bloomberg, two hackers broke into a private GitHub repo used by Uber software engineers, and were able to gain access to an Amazon Web Services account that handled and controlled tasks by the ride-sharing service. The hackers found a trove of rider and driver data, downloaded it, and reportedly emailed the company demanding money.

Uber has said, however, that individual riders do not need to take "any action," following the announcement.

The Wild Neutron hacking group gained access to an internal database Microsoft uses to track software vulnerabilities.
David Bisson reports.

On 17 October 2017, five former employees revealed that at the time of the breach Microsoft raised a number of internal alarms signaling that hackers had compromised the database it uses to track patches.

The attack has been blamed on Wild Neutron, a sophisticating hacking group which has targeted Apple, Facebook, and a number of other multi-billion dollar companies.

Even so, the former Microsoft workers said the database was poorly protected by just a single password.

Concerned that the hacking group had stolen details on some of its open vulnerabilities for Windows and other software, Microsoft decided to look at other industry breaches and investigate the timing of those event with respect to when the flaws entered its database.

Deloitte, one of the world's biggest accounting, auditing, and corporate finance consulting firms, has suffered a data breach.

Third hack at a financial institution this month

The company is one of the so-called "Big Four" accounting firms, together with Ernst & Young, KPMG, and PricewaterhouseCoopers. The Big Four provide accounting and other financial services to almost all major businesses across the globe.

The Deloitte hack is the third security breach at a major financial agency this month alone, after similar incidents at Equifax and the US Securities and Exchange Commission (SEC).

Kreditkarten-, Sozialversicherungs- und Ausweisnummern von mehreren Hundert Millionen US-Amerikanern sind in falsche Hände gelangt, als Equifax monatelang gehackt war. Dazu kommen weitere Opfer in Kanada und dem Vereinigten Königreich.

The account details of millions of subscribers to the education platform Edmodo have not only been stolen but witnessed to be for sale on the dark web, according to a post on Motherboard.

The platform is used by more than 78 million teachers, students and parents to compose lesson plans, make homework assignments and other tasks.

Breach notification website LeakBase provided Motherboard with a sample of more than two million records, which included usernames, email addresses and hashed passwords. 
The good news is that the passwords apparently are hashed with the stealthy bcrypt algorithm, and a string of random characters known as a salt, which likely will make it more difficult for hackers to obtain users' login credentials. And, when staffers at Motherboard attempted to open Edmodo accounts using some of the purloined data, they were unsuccessful as the address was already linked to an Edmodo account, the report explained.

The bad news is that at least a portion of the database is up for sale on the dark web marketplace Hansa for $1,000. The seller, going under the name nclay, said s/he was in possession of 77 million accounts. LeakBase reported that 40 million of those come with an email address.
