The decryptor is of little use to other companies hit in the spate of attacks unleashed before the notorious ransomware group went dark, researchers said.

In one of the largest cryptocurrency hacks to date, cyberattackers reportedly stole millions from the decentralized finance (DeFi) platform Poly Network.

Experts urged enterprises to patch fast: SAP vulnerabilities are being weaponized in a matter of hours.

Cobolt Strike is a security tool, used by penetration testers to simulate network attackers. But it’s also used by attackers — from criminals to governments — to automate their own attacks. Researchers have found a vulnerability in the product.

The main components of the security tool are the Cobalt Strike client — also known as a Beacon — and the Cobalt Strike team server, which sends commands to infected computers and receives the data they exfiltrate. An attacker starts by spinning up a machine running Team Server that has been configured to use specific “malleability” customizations, such as how often the client is to report to the server or specific data to periodically send.

Then the attacker installs the client on a targeted machine after exploiting a vulnerability, tricking the user or gaining access by other means. From then on, the client will use those customizations to maintain persistent contact with the machine running the Team Server.

The link connecting the client to the server is called the web server thread, which handles communication between the two machines. Chief among the communications are “tasks” servers send to instruct clients to run a command, get a process list, or do other things. The client then responds with a “reply.”

Researchers at security firm SentinelOne recently found a critical bug in the Team Server that makes it easy to knock the server offline. The bug works by sending a server fake replies that “squeeze every bit of available memory from the C2’s web server thread….”

It’s a pretty serious vulnerability, and there’s already a patch available. But — and this is the interesting part — that patch is available to licensed users, which attackers often aren’t. It’ll be a while before that patch filters down to the pirated copies of the software, and that time window gives defenders an opportunity. They can simulate a Cobolt Strike client, and leverage this vulnerability to reply to servers with messages that cause the server to crash.

As outlined in Executive Order on Improving the Nation’s Cybersecurity (EO 14028), Section 3: Modernizing Federal Government Cybersecurity, CISA has been tasked with developing a Federal cloud-security strategy to aid agencies in the adoption of a Zero Trust Architecture to meet the EO Requirements. While the government awaits the completion of that effort, I think it’s important to look at the two government reference architectures that have already been published, as they will undoubtedly be considered in the development of CISA’s cloud-security strategy. Both NIST (800-207) and DoD (Version 1.0) have released Zero Trust reference architectures. Both define a Zero Trust telemetry architecture informed by security sensors to dynamically evaluate device and user trust and automatically change access permissions with changes in entity trust. They each accomplish the same goal, even if they take slightly different paths to get there.

Whereas the DoD architecture establishes control planes that each have their own decision point, with data given its own decision point, NIST takes a broader approach to Zero Trust and emphasizes Zero Trust in relation to all resources, not just data. The data control plane within the DoD architecture encompasses data processing resources and applies data-specific context to them. As most networks, applications, storage and services exist to process and store data, it makes sense that access to these resources should be specific to the data contained within them, and not just the access to the resources themselves. Protecting data is central to Zero Trust, and the DoD’s architecture acknowledges this.

Data Centric Enterprise

Today, most Zero Trust efforts seem to focus on defending the applications, networks and services that contain the data but fall short of building data specific protections. And while protecting network, application, and service resources is certainly important and essential to layered protections, improving protection around the data is imperative to successfully adopt Zero Trust architecture. People with alarm systems on their homes still lock up valuables in a safe to guard against failures in controls, or less than trustworthy house guests and hired workers.

The DoD puts data at the center of its reference architecture. User and entity trust is assessed in relation to the data being accessed, and permission levels are dynamically changed specific to individual data resources.  If Zero Trust operates under the assumption that networks and applications are already compromised, then the only logical way to successfully implement Zero Trust is to combine network, application, and service access technologies with a comprehensive data protection platform. In a well-designed Zero Trust architecture, a comprehensive data protection platform serves not only to protect data, but also as a means to inform the analytics layer of potentially malicious insiders or compromised user accounts in order to automatically trigger changes in access permissions.

Imagine a very simple scenario where an organization has classified specific types of data and implemented controls to protect the data. Jane is a contractor, who, because of her contract function, was vetted and cleared for access to critical applications and controlled unclassified data. Jane has a government-issued laptop with data protection software, and she has access to government cloud applications like Office 365 that are protected and governed by the agencies’ CASB solution. Unfortunately, Jane has been having well disguised and undisclosed financial troubles, which have put her in a compromised situation. In order to try to get herself out of it, she has agreed to act as an insider. Jane initially attempts to send sensitive data to herself through her Office 365 email, but the attempt is blocked by the CASB. She then attempts to share the records from SharePoint to an untrusted email domain and again is blocked by the CASB and reported to security. Desperate, she tries to move the data to an external hard drive, and yet again she is blocked. At this point, Jane gives up and realizes the data is well protected.

On the backend of this scenario, each one of these attempts is logged as an incident and reported. These incidents now inform a Zero Trust dynamic access control layer, which determines that Jane’s trust level has changed, resulting in an automatic change to her user access policies and a Security Operations alert. This is one very basic example of how a data protection platform can inform and affect user trust.

What Comprises a Comprehensive Data Protection Platform?

Effectively architecting a comprehensive data protection platform requires a multi-vector and integrated approach.  The platform should be a combination of control points that leverage a common classification mechanism and a common incident management workflow. Data protection enforcement should facilitate enforcement controls across managed hosts, networks, SaaS, and IaaS resources, and whenever possible restrict sensitive data from being placed into areas where there are no controls.

McAfee enables this today through a Unified DLP approach that combines:

• Host Data Loss Prevention (DLP)
• Network Data Loss Prevention (DLP)
• Cloud Access Security Broker (CASB)
• Hybrid Web Gateway – On-Premises and SaaS
• Incident Management

This comprehensive approach enables data protection policies to follow the data throughout the managed environment, ensuring that enterprise data is protected at rest, in transit, and in use. Within the platform, user trust is evaluated conditionally based on policy at each enforcement point, and any change to a user’s group through the Zero Trust architecture automatically modifies policies within the data protection platform.

What Next?

Data protection has long been a challenge for every enterprise. Successful implementation of data protection technologies requires a programmatic effort that includes data owners to accurately and successfully identify and build protections around sensitive information. If not implemented properly, data protection opens the door to user disruptions that many organizations have very little tolerance for. That’s why so many organizations focus their efforts on improving perimeter and access protections. Adversaries know this, which is why compromising user credentials or the supply chain to gain access remains a highly leveraged entry point for threat actors, because perimeter and access control protections fail to guard against people already inside the network with appropriate access. As enterprises plan for Zero Trust architectures, data protection has to take center stage.

By mandating that agencies quantify the type and sensitivity of their unclassified data, the EO appears to be steering Executive Branch agencies down the path of data centricity. The Executive Order focuses on improving the adoption of encryption best practices around data and implementing multifactor authentication in an effort to protect access to sensitive data from malicious outsiders. It falls short, however, of encouraging broad adoption of data loss prevention architectures to protect against accidental and malicious data leakage.

CISA has an opportunity to prioritize data as an enterprise’s central resource in their upcoming cloud-security strategy, which will drive agency adoption of Zero Trust Architecture. They should take this opportunity to emphasize the importance of designing a comprehensive data protection platform to serve as both a trust identifier and a mechanism of protection.

For some, vanquishing aliens, building virtual amusement parks, and online battles royale are an excellent stress reliever. As we all know, over the past year there’s been plenty of stress to relieve and more spare time on our hands in which to revel in our hobbies. There was a 30% jump in online gaming traffic from the first to the second quarter of 2020. 

Hackers are taking advantage of highly trafficked online gaming portals to make a profit on the dark web. The next time you log on to your virtual world of choice, consider these recent video game breaches and up your gamer security, which could include an antivirus for gaming.  

Recent Game Hacks

Between 2019 and 2020, web attacks on gaming companies rocketed up 340%, according to Akamai. Hackers have targeted several high-profile gaming companies recently with various motives. First, game source code was stolen from Electronic Arts to sell on the dark web. Developers shopping the dark web use stolen source codes to reverse-engineer popular games or copy the code into their own game. Capcom and CD Projekt Red were hit by ransomware attacks only a few months apart from each other, one attack focused on company financial information and the other on source code. 

“Titan Fall” and “Apex Legends” have both been hacked to the point where the former is unplayable, according to many gamers. To protest “Titanfall’s” developers’ inaction, gamers took to “Apex Legends,” altering in-game messages. The apparent ease with which hackers can walk into online gaming portals requires that game developers and gamers themselves pay more attention to their security. 

Online PC gaming allows players to use real-world money to purchase valuable upgrades to their characters. These characters receive admiration from some fellow players. Others feel greed. Advanced characters can fetch a lot of money on the dark web, so some cybercriminals practice credential stuffing to force their way into player accounts and steal ownership. Credential stuffing is a type of brute force attack where hackers take informed guesses at username and password combinations. A strong password or passphrase is essential to keeping your account and investment safe from a dark web fate. 

Why Are Video Games Hacked?

Based on the above recent hacks, it is clear that gaming companies host a trove of valuable information. Gamers trust these platforms with their payment information and with the safety of their gaming characters on which they spend thousands of hours and hundreds of dollars upgrading, making gaming a lucrative target for hackers. 

Another way cybercriminals target gamers is through malware disguised as an advantage. Cheat software for online games is common as players strive to be the best out of thousands. Advantage seekers for “Call of Duty: Warzone” were targeted by a malware scam. The malware creators advertised the “cheat software” on YouTube with instructions on how to download it. The video received thousands of views and hundreds of comments, which made it look legitimate. 

One of the steps in installing the “cheat software” was that users had to disable antivirus programs and firewalls. Users let the cybercriminals walk right into their device! From there, the device was infected by an aggressive type of fileless malware called a dropper. A dropper doesn’t download a malicious file onto the device; rather, it creates a direct pathway to deliver an additional payload, such as credential-stealing malware. 

Gamer Security Tips

Competitive gaming is, well, competitive. So, if you invest a lot of real money into your characters, be especially vigilant and follow these five important tips to protect your online accounts. 

1. Do not reveal personal information 
   

It’s common for gamers to use variations of their real names and birthdates in their public-facing usernames. Don’t use your real name or birthdate in your username. Consider using a nickname or a combination of random numbers instead. Along this same vein, don’t reveal personal details about yourself (phone number, birthday, places you visit regularly) on chats or streams. Lurking cybercriminals can gather these personal details to impersonate you. 

2. Edit your privacy settings  
   

On some online PC games, you can join campaigns with gamers from all over the world. While the interconnectivity is great, carefully vet who you allow to follow your online profile. If a stranger sends a friend request out of the blue, be on alert. They could have nefarious motives, such as phishing for valuable personal data. It’s best to customize your privacy settings to make your profile invisible to strangers.  

3. Don’t pirate games or download cheat software

Developers spend a lot of time creating amazing games, so make sure you purchase games legally and play them as they are intended. Be especially wary of free downloads or pirated versions and cheat software, as they’re likely too good to be true. Instead, go for a challenge and have fun with the game as it’s written.  

4. Log in with a VPN

A virtual private network (VPN) scrambles your online data traffic, making it impossible for hackers to access your IP address and spy on your online browsing. 

5. Sign up for gaming antivirus software 

Gaming antivirus software not only makes your online gaming experience more secure, but it can boost your rig’s performance! McAfee Gamer Security detects threats through the cloud and optimizes resources to minimize frame drops.
