Microsoft Wants More Security Researchers to Hack Into Its Cloud
Russinovich spoke about protecting the cloud at an academic conference at Microsoft attended by hundreds of Microsoft workers and security engineers from Amazon Web Services, Google, Nike Inc. and others. The event grew out of a trail-running group that includes Microsoft’s Ram Shankar Siva Kumar, who oversees a team of engineers who apply machine-learning to cybersecurity, and peers at AWS and Google. The group would often share techniques and research while on the trail and the idea for a formal conference to exchange ideas was born.

Data-tracking Chrome flaw triggered by viewing PDFs – Naked Security
Researchers have spotted an unusual ‘trackware’ attack triggered by viewing a PDF inside the Chrome browser.

Security company EdgeSpot said it noticed suspicious PDFs, which seem to have been circulating since 2017, sending HTTP POST traffic to the tracking site

The behaviour only happened when a user viewed a PDF using desktop Google Chrome – when opened in Adobe Reader the PDF’s behaviour returned to normal.

Data sent included the user’s IP address, the Chrome and OS versions, and the full path of the PDF on their computer.

USPS Site Exposed Data on 60 Million Users — Krebs on Security
The API in question was tied to a Postal Service initiative called “Informed Visibility,” which according to the USPS is designed to let businesses, advertisers and other bulk mail senders “make better business decisions by providing them with access to near real-time tracking data” about mail campaigns and packages.

In addition to exposing near real-time data about packages and mail being sent by USPS commercial customers, the flaw let any logged-in user query the system for account details belonging to any other users, such as email address, username, user ID, account number, street address, phone number, authorized users, mailing campaign data and other information.

Many of the API’s features accepted “wildcard” search parameters, meaning they could be made to return all records for a given data set without the need to search for specific terms. No special hacking tools were needed to pull this data, other than knowledge of how to view and modify data elements processed by a regular Web browser like Chrome or Firefox.

You dirty DRAC: IT bods uncover Dell server firmware security slip • The Register
Jon Sands and Adam Nielsen discovered and reported via Serve The Home a bug dubbed iDRACula because it involves Dell's iDRAC service. iDRAC is software that runs on the baseband management controller (BMC) inside a PowerEdge system independent of whatever hypervisor, operating system, and applications are running.

It has full control over the hardware. Administrators can connect over the network to a server's iDRAC to diagnose and fix up any problems. It's a lot easier to fire up a web browser, and remotely power cycle the box or reinstall its OS, than locate, pull out, repair, and re-rack a system by hand, for instance.

The weakness is said to be present in 12th and 13th Dell EMC PowerEdge generations. The latest machines, 14th-gen and up, are not vulnerable because they introduced a root-of-trust in the BMC processor, meaning only Dell-authorized code can run on the controller, and not junk injected by hackers.

A Major Bug In Bitcoin Software Could Have Crashed the Currency - Motherboard
On Tuesday, the developers of Bitcoin Core—the software that effectively powers the Bitcoin blockchain—released a new version that patched a vulnerability that allowed a malicious user to crash the network, making everyone’s digital coins effectively useless. The bug has been variously described as “very scary,” “major,” and one of the “top three or four” most serious bugs ever discovered in Bitcoin.
“For less than $80,000, you could have brought down the entire network,” Emin Gün Sirer, an associate professor of computer science at Cornell University told me over the phone. “That is less money than what a lot of entities would pay for a 0-day attack on many systems. There are many motivated people like this, and they could have brought the network down.”

The Tale of SettingContent-ms Files – Posts By SpecterOps Team Members
This is why attackers have resorted to Object Linking and Embedding (OLE), ZIP files, etc. To combat the file delivery vector, Office 2016 introduced blocking all of the “dangerous” file formats from being embedded via OLE by default. This reduces the effectiveness of one of the most relied upon payload delivery methods

I stumbled across the “.SettingContent-ms” file type. This format was introduced in Windows 10 and allows a user to create “shortcuts” to various Windows 10 setting pages. These files are simply XML and contain paths to various Windows 10 settings binaries.

As you can see, with Office 2016’s OLE block rule and ASR’s Child Process Creation rule enabled, .SettingContent-ms files combined with “AppVLP.exe” in the Office folder allow us to circumvent these controls and execute arbitrary commands.

While Office documents are often marked with MOTW and are opened in the Protected View Sandbox, there are file formats that allow OLE and aren’t triggered by the Protected View sandbox. You can find more on that here.

6/4/2018: MSRC responded with a note that the severity of the issue is below the bar for servicing and that the case will be closed.

NPM update changes critical Linux filesystem permissions, breaks everything – Naked Security
For example, JavaScript programs in your browser generally can’t reach out into other tabs, can’t start or stop other programs, can’t access files on your hard disk, can’t read the registry, can’t scan the network, can’t sniff around in memory.

Unlike browser JavaScript, Node.js is augmented by add-on toolkits to do just about anything you can think of: manage processes, run servers, read local files and databases, control the network, perform cryptographic calculations, transcode images and videos, recognise faces, you name it.

You may find you can write a five-line JavaScript program that is elegantly simple, but only if your Node Package Manager drags in tens or even hundreds of thousands of lines of other people’s software.

Automatically. From all over the internet.

I found that a selection of directories in / were owned by a non-root user after running sudo npm and many binaries in /usr/bin stopped working as their permissions were changed. People experiencing this bug will likely have to fully reinstall their system due to this update.

Keep backups that make a meaningful rollback easy. NPM has caused reliability disasters before, and given its vaguely anarchical nature, will cause them again.
Skip the 5.7.0 version of NPM. NPM version 5.7.1 is supposed to fix this bug.
Don’t autoupdate production or development servers. Prove the latest update in testing first.
Remember that simple software can be immensely complex. Keep that in mind when making time for testing (see 3).

“It wasn’t a case of having to write software to do this. You could literally just cut and paste what they said in the paper and use it. The video of how easy it was to use, that was the thing that clinched it for me—sitting and watching a video of someone just clicking a few buttons and being able to exfiltrate data.”

Bad RSA Library Leaves Millions of Keys Vulnerable | Hackaday
So, erm… good news everyone! A vulnerability has been found in a software library responsible for generating RSA key pairs used in hardware chips manufactured by Infineon Technologies AG. The vulnerability, dubbed ROCA, allows for an attacker, via a Coppersmith’s attack, to compute the private key starting with nothing more than the public key, which pretty much defeats the purpose of asymmetric encryption altogether.

Affected hardware includes cryptographic smart cards, security tokens, and other secure hardware chips produced by Infineon Technologies AG. The library with the vulnerability is also integrated in authentication, signature, and encryption tokens of other vendors and chips used for Trusted Boot of operating systems. Major vendors including Microsoft, Google, HP, Lenovo, and Fujitsu already released software updates and guidelines for mitigation.

The following key length ranges are now considered practically factorizable (time complexity between hours to 1000 CPU years at maximum): 512 to 704 bits, 992 to 1216 bits and 1984 to 2144 bits. Note that 4096-bit RSA key is not practically factorizable now, but may become so, if the attack is improved.

The time complexity and cost for the selected key lengths (Intel E5-2650 v3@3GHz Q2/2014):

512 bit RSA keys – 2 CPU hours (the cost of $0.06);
1024 bit RSA keys – 97 CPU days (the cost of $40-$80);
2048 bit RSA keys – 140.8 CPU years, (the cost of $20,000 – $40,000).

Cutting-edge hack gives super user status by exploiting DRAM weakness | Ars Technica
"The thing that is really impressive to me in what we see here is in some sense an analog- and manufacturing-related bug that is potentially exploitable in software," David Kanter, senior editor of the Microprocessor Report, told Ars. "This is reaching down into the underlying physics of the hardware, which from my standpoint is cool to see. In essence, the exploit is jumping several layers of the stack."

vulnerability works only on newer types of DDR3 memory and is the result of the ever smaller dimensions of the silicon. With less space between each DRAM cell, it becomes increasingly hard to prevent one cell from interacting electrically with its neighbors

Schneider Electric: TRITON/TRISIS Attack Used 0-Day ...
chneider's controller is based on proprietary hardware that runs on a PowerPC processor. "We run our own proprietary operating system on top of that, and that OS is not known to the public. So the research required to pull this [attack] off was substantial," including reverse-engineering it, Forney says. "This bears resemblance to a nation-state, someone who was highly financed."

The attackers also had knowledge of Schneider's proprietary protocol for Tricon, which also is undocumented publicly, and used it to create their own library for sending commands to interact with Tricon, he says.

Forney points out that the malware technically had infected the safety controller, and the "attack itself would come much later" if it had not been found out.

TRITON/TRISIS is an attack framework made up of the two programs: one exploits the Triconex zero-day flaw to escalate user privileges and allowed the attacker to manipulate the firmware in RAM and then implant the RAT, the second program, according to Schneider.

In its customer advisory, Schneider recommends:

Ensure the cybersecurity features in Triconex solutions are always enabled.
Safety systems must always be deployed on isolated networks.
Physical controls should be in place so that no unauthorized person would have access to the safety controllers, peripheral safety equipment or the safety network.
All controllers should reside in locked cabinets and never be left in the “PROGRAM” mode.
All Tristation engineering workstations should be secured and never be connected to any network other than the safety network.
All methods of mobile data exchange with the isolated safety network such as CDs, USB drives, DVD’s, etc. should be scanned before use in the Tristation engineering workstations or any node connected to this network.
Laptops and PCs should always be properly verified to be virus and malware free before connection to the safety network or any Triconex controller.
Operator stations should be configured to display an alarm whenever the Tricon key switch is in the “PROGRAM” mode.

Hackers Start Exploiting Recently Found Flaws in GPON Routers - Security Boulevard
internet gateway devices used for residential gigabit-capable passive optical networks (GPON).

The vulnerabilities were found by a company called vpnMentor and affect GPON routers made by DASAN Networks, a global provider of networking solutions and customer premises equipment used by ISPs.

This incident highlights the risks associated with using ISP-supplied home networking equipment. Custom-branded devices that are used by multiple ISPs from around the world are often made by the same OEM and share the same underlying firmware.

This makes it difficult to identify all vulnerable devices when a security issue is found. It’s also highly unlikely that any patch released by an OEM will ever reach all affected devices, since those patches need to be distributed by every ISP that uses those devices.

Meltdown and Spectre
Meltdown and Spectre exploit critical vulnerabilities in modern processors. These hardware bugs allow programs to steal data which is currently processed on the computer. While programs are typically not permitted to read data from other programs, a malicious program can exploit Meltdown and Spectre to get hold of secrets stored in the memory of other running programs. This might include your passwords stored in a password manager or browser, your personal photos, emails, instant messages and even business-critical documents.

Meltdown and Spectre work on personal computers, mobile devices, and in the cloud. Depending on the cloud provider's infrastructure, it might be possible to steal data from other customers.
