Ransomware continues to grow more sophisticated and lucrative, and now security firm LIFARS says operators have built a Silicon Valley-like VC ecosystem.
SAN FRANCISCO, June 25 (Reuters) — Microsoft (MSFT.O) said on Friday an attacker had won access to one of its customer-service agents and then used information from that to launch hacking attempts against customers.
The company said it had found the compromise during its response to hacks by a team it identifies as responsible for earlier major breaches at SolarWinds (SWI.N) and Microsoft.
Microsoft said it had warned the affected customers. A copy of one warning seen by Reuters said the attacker belonged to the group Microsoft calls Nobelium and that it had access during the second half of May.
The artificial intelligence revolution is just getting started. But it is already transforming conflict. Militaries all the way from the superpowers to tiny states are seizing on autonomous weapons as essential to surviving the wars of the future. But this mounting arms-race dynamic could lead the world to dangerous places, with algorithms interacting so fast that they are beyond human control. Uncontrolled escalation, even wars that erupt without any human input at all.
DW maps out the future of autonomous warfare, based on conflicts we have already seen – and predictions from experts of what will come next.

Rather than steal credentials or hold data for ransom, a recent campaign observed by Sophos prevents people from visiting sites that offer illegal downloads.
The objective of most malware is some kind of gain — financial or otherwise — for the attackers who use it. However, researchers recently observed a unique malware with a single intent: Blocking the infected computers from visiting websites dedicated to software piracy.
The malware (which SophosLabs principal researcher Andrew Brandt called “one of the strangest cases I’ve seen in a while”) works by modifying the HOSTS file on the infected system, in a “a crude but effective method to prevent a computer from being able to reach a web address,” he wrote in a report published Thursday.
A malware called Crackonosh infected 222000 PCs in order to mine $2 million worth of Monero cryptocurrency.
Cybersecurity experts reported the detection of at least four flaws in Dell SupportAsist’s BIOSConnect feature, the exploitation of which would allow threat actors to deploy remote code to affected devices. It should be noted that this software is preinstalled by default on most Dell computers running Windows systems, and BIOSConnect allows remote firmware update and some operating system recovery features.
This set of flaws received a score of 8.3÷10 on the Common Vulnerability Scoring System (CVSS) scale, and its exploitation would allow privileged remote hackers on the target system to impersonate an official Dell service in order to take control of the operating system boot process and thus break any security controls enabled. So far no active exploitation attempts or a functional attack have been detected for the abuse of these flaws.

Microsoft, via its Security Intelligence account on Twitter, has issued a warning to Windows users of a new type of phishing scam that involves emails requesting users to dial a call center. They warn users to not dial the call center because following the instructions given by a human operator can lead to malware infections. The malware scam only works with Windows computers that have Microsoft Excel.
The new threat involves BazarLoader, a type of malware that allows backdoor access to infected computers. BazarLoader works by allowing criminals to sneak in through a hidden backdoor on a user’s computer, which allows them to install viruses or other types of malware. Over the past several years, criminals have used different methods to trick users into carrying out instructions that allow BazarLoader to infect their computer. In this new campaign, Microsoft reports that such criminals are using an email/call center approach.

Cyber criminals are increasingly using virtual machines to compromise networks with ransomware.
By using virtual machines as part of the process, ransomware attackers are able to conduct their activity with additional subtlety, because running the payload within a virtual environment reduces the chances of the activity being discovered – until it’s too late and the ransomware has encrypted files on the host machine.
During a recent investigation into an attempted ransomware attack, cybersecurity researchers at Symantec found the ransomware operations had been using VirtualBox – a legitimate form of open-source virtual machine software – to run instances of Windows 7 to aid the installation of ransomware.
