This gives Windows Defender ATP granular control on which actions are more interesting and may require more attention. Every day, memory scanning allows Windows Defender ATP to protect thousands of machines against active high-profile threats like Mimikatz and WannaCry.

With Controlled folder access on Windows 10, Windows Defender ATP does not allow write operations to the boot sector, thus closing a dangerous fileless attack vector used by Petya , BadRabbit , and bootkits in general. Boot infection techniques can be suitable for fileless threats because they can allow malware to reside outside of the file system and gain control of the machine before the operating system is loaded. The use of rootkit techniques, like in the defunct Alureon malware also known as TDSS or TDL-4 , can then render the malware invisible and extremely difficult to detect and remove.

Windows 10 in S mode comes with a preconfigured set of restrictions and policies that make it naturally protected against a vast majority of the fileless techniques and against malware in general. Among the available security features, the following ones are particularly effective against fileless threats:.

For executables : Only Microsoft-verified applications from the Microsoft Store are allowed to run. For macros : Office does not allow the execution of macros in documents from the internet for example, documents that are downloaded or received as attachment in emails from outside the organization. For exploits : Exploit protection and Attack surface reduction rules are also available on Windows 10 in S mode as a consistent barrier against exploitation.

With these restrictions in place, Windows 10 in S mode devices are in a robust, locked down state, removing crucial attack vectors used by fileless malware. As antivirus solutions become better and better at pinpointing malicious files, the natural evolution of malware is to shift to attack chains that use as few files as possible.

While fileless techniques used to be employed almost exclusively in sophisticated cyberattacks, they are now becoming widespread in common malware, too.

At Microsoft, we actively monitor the security landscape to identify new threat trends and develop solutions that continuously enhance Windows security and mitigate classes of threats. We instrument durable generic detections that are effective against a wide range of threats. Through AMSI, behavior monitoring, memory scanning, and boot sector protection, we can inspect threats even with heavy obfuscation. Machine learning technologies in the cloud allow us to scale these protections against new and emerging threats.

Security solutions on Windows 10 integrate into a unified endpoint security platform in Windows Defender Advanced Threat Protection. Windows Defender ATP includes attack surface reduction, next-generation protection, endpoint protection and response, auto investigation and remediation, security posture, and advanced hunting capabilities.

Protections against fileless and other threats are shared across Microsoft , which integrate technologies in Windows, Office , and Azure. Through the Microsoft Intelligent Security Graph, security signals are shared and remediation is orchestrated across Microsoft Questions, concerns, or insights on this story?

The breadth of telemetry, the strength of threat intelligence, and the advanced, automatic detection through machine learning, heuristics, and behavior monitoring delivered comprehensive coverage of attacker techniques across the entire attack chain.

Generically detecting fileless techniques The two aforementioned obfuscated scripts are actual malware detected and blocked in the wild by antivirus capabilities in Windows Defender ATP. Figure 1. After de-obfuscation, the script contains functions typically used in the Sharpshooter technique When the Sharpshooter technique became public, we knew it was only a matter time before it would be used it in attacks.

Figure 4. Windows Defender ATP telemetry shows two Sharpshooter campaigns in June Furthermore, generically detecting the Sharpshooter technique allowed us to discover a particularly sophisticated and interesting attack.

Figure 5. Figure 6. The core component of the malware is decrypted and executed from memory Our investigation into the incident turned up enough indicators for us to conclude that this was likely a penetration testing exercise or a test involving running actual malware, and not a real targeted attack.

Upward trend in fileless attacks and living off the land Removing the need for files is the next progression of attacker techniques. A is abusing mshta. Figure 8. To shed light on this loaded term, we grouped fileless threats into different categories. Figure 9.

Taxonomy of fileless threats We can classify fileless threats by their entry point i. Type I: No file activity performed. A completely fileless malware can be considered one that never requires writing a file on the disk.

Type II: No files written on disk, but some files are used indirectly. There are other ways that malware can achieve fileless presence on a machine without requiring significant engineering effort. Fileless malware of this type do not directly write files on the file system, but they can end up using files indirectly.

Type III: Files required to achieve fileless persistence. Some malware can have some sort of fileless persistence but not without using files in order to operate. Defeating fileless malware with next-gen protection File-based inspection is ineffective against fileless malware. Figure JAC The payload does not have any obfuscation and is very easy to detect, but it never touches the disk and so could evade file-based detection.

Detections of the PowerShell reverse TCP payload Beyond looking at events by process, behavior monitoring in Windows Defender ATP can also aggregate events across multiple processes, even if they are sparsely connected via techniques like code injection from one process to another i. A technique detected in the wild Recently, we saw a sudden increase in Pyordono.

The obfuscated macro code attempts to run an obfuscated Cmd command which in turns executes an obfuscated Powershell script. They only caught 2 and they never recovered the laptop. No one is going back to the office anytime soon. Maybe ever.

LUKS has 8 slots for decryption keys, so other people can have their access to the same system too. No hibernation. No standby. Of course, once the computer is booted and the storage is unlocked, it is crackable due to normal security faults. With physical access, eventually, someone can get in. My simple mind would have expected the TPM to be mounted on the cpu chip header to avoid bus exposure. This system that was cracked was set up to trust the machine, not the person holding it.

Well, hello? Systems like this are not intended to be secure, they are intended to sell seats for Windows. As per my comments in the Squid topic on models of reasoning this article by Arstechnica is part of the con by Microsoft to sell more product.

The security industry seems very mute both on the log chain of failures by Intel and Microsoft and others who brought us to this point. The software, hardware, and and media industries and, yes, security industry seem to behaving like the wife beater who bought his wife a bunch of flowers from the housekeeping he has been withholding. Something whiffs not just about this article but the timing of this article but more importantly what is said and not said by Arstechnica especially.

The refusal to update a bios to support secure boot or TPM 2. There was also the case of unused payload in one of their firmware or software updates I forget which which could be used by an exploit to reduce its payload size. Then there is the spurious whitelisting of modems in the mini PCIE socket. Without a hacked BIOS who wants that? I am not ruling out legal or political action on any of these fronts whether it involves the courts or regulators or whoever.

I am also not above questioning whether UK government policy and regulation is legal and by this not just one narrow policy area but a broad spectrum of policy areas. Nobody trusts Windows! America has a lot of work to do pulling its socks up with respect of human rights and social policy and I know plenty of Americans agree.

Not that this lets Russia or China or even the UK off the hook. Whilst there are known structured and layered solutions to both 1 and 2 we are only marginally closer than we wwre last century on 3. The first two 2. The other two need to be selected with care in other ways to long to go into here.

The grandiose sum would be more than the annual revenues of Uniloc, company officials said. But Uniloc, which was founded in Australia in and established U. Uniloc today is announcing that it will take its device recognition technology and use it to protect critical infrastructure such as water, power, oil and gas, and chemicals and transportation.

Uniloc's software crawls through a PC or other device to find serial codes on hard drives, mother boards and network cards, and variations in chipsets and components including video and sound cards and RAM.

Because all PCs contain physical imperfections, and many components with unique serial numbers, Uniloc is able to create a fingerprint that can distinguish any PC from any other. Uniloc sells the technology to software and gaming companies under the name SoftAnchor, which helps prevent their products from being used on unauthorized devices.

Sega and Maximum Software are among SoftAnchor's users. Today, Uniloc is announcing the availability of NetAnchor, which uses the same device recognition technology to assign trusted user status to devices that need access to critical infrastructure in oil and gas and other industries.

Any device that hasn't been confirmed as trusted is denied access. One large oil company is already using NetAnchor, Davis says, noting that an oil company might face thousands of attacks every day from hackers attempting to take control of critical assets. With NetAnchor, a hacker could steal loads of usernames and passwords but still be denied access if he's not using a trusted device.
