You Can Now Block People from Adding you to Groups Thanks to this New Whatsapp Privacy Feature

Published

on

Ever get tired of being added to different Whatsapp groups without your permission? Well Whatsapp is finally rolling out a solution for that problem.
Whatsapp announced on Wednesday the introduction of new privacy features that lets users limit who can add them to group chats.

One notable privacy feature is the introduction of an invite system that basically requires a user’s consent before they can be added to groups. Under this system, users will receive an invite link which carries basic information about the group. Users can choose to join the group via that link; otherwise the link expires in 24 hours.

Whatsapp Now Allows You Block People From Adding You To Groups

Even better, Whatsapp has introduced a feature that allows you to block anyone from being able to add you at all.

With the new privacy feature, you can select who can send you group invites.

Options available include “everyone”, “my contacts” or you can choose to block all invites totally using the “Nobody” option. These options are available under Account > Privacy > Groups in the Whatsapp settings.

Whatsapp announced that the new features are part of updates rolled out beginning on Wednesday. Full global rollout is expected to be completed over the next few weeks.View image on Twitter

Whatsapp group is a highly functional and timely feature, but it’s also one of the most abused Whatsapp feature. Without seeking user permission, administrators of different Whatsapp groups annoyingly add users to groups.

Some users immediately choose to leave these groups. But some others may not feel like they can leave. For family groups and groups created by someone they know, users feel guilty leaving or hate it when their exit is announced by Whatsapp. As a result, more Whatsapp users prefer not even joining these groups in the first place.

Whatsapp Using New Groups Privacy Feature To Address Fake News

However beyond this, the latest group restriction plays well in the fight against fake news. In countries like Brazil and India, Whatsapp groups are important points to spread fake and misleading news.

It shows contempt for the voters to seek to exploit their ignorance of the source & context, which in any case was accurate about the past it describes. Unfortunately many are taken in by these lies. BJP is incapable of being ashamed of itself; but why can’t social media act?

I call on those who run @whatsApp, @Facebook & @Twitter in India&who claim to be concerned about the misuse of their platforms by political fake-news peddlers to make an example of this specimen, to start with. The echo-chamber repeating her lies is part of an organised campaign.1,8588:06 PM – Apr 3, 2019Twitter Ads info and privacy533 people are talking about this

Several reports show that in India, some political parties create groups based on caste, income levels and religion. With this classification, they bombard these groups with different reports designed to influence their thinking and conversations.

To address these issues, Whatsapp has already introduced several features. Some include labeling forwarded messages and limiting the number of times a message can be forwarded to five.

The new group invites system and blocking tools will help protect users even further.

2 Companies Ready For a Huge Cybersecurity Opportunity

Published

on

By

It was always there. But it would be naive to say the COVID-19 pandemic hasn’t accelerated the cybersecurity market’s growth pace. With millions of employees still — and perhaps permanently — working from home, many enterprises remain far too vulnerable to hacking and digital security breaches.

The depth of the need for cybersecurity solutions, however, may still not be fully appreciated by investors. That in turn means that cybersecurity providers Palo Alto Networks (NYSE:PANW) and Fortinet (NASDAQ:FTNT) may remain underestimated. Not only are they two of the top names in the business, but each has a security solution available right now for employees connecting to a company’s network from home.

A couple of recent predictions flesh out this opportunity.

Just the beginning

The cybersecurity market is currently worth around $200 billion, according to numbers from Mordor Intelligence, but it’s on pace to grow a bit more than 14% per year through 2025. That’s impressive, particularly compared to other industries’ growth outlooks.

But it’s an estimate that still fails to adequately paint a complete picture of what the right company could do given the opportunity at hand. Even with power players like the aforementioned Fortinet and Palo Alto in place, Mordor says the market remains highly fragmented. Both companies could continue to make acquisitions, achieving economies of scale as they expand.

Even without dealmaking, though, the industry’s rising tide will lift these boats.

Technology market research firm Gartner supplies one of the clearest reasons to expect that tide to keep rising. Last month it opined that “bring your own PC,” or BYOPC, security will be normalized in five years or less. And within 10 years, secure access service edge, or SASE, will be the norm for enterprise-level organizations.

The terms and their acronyms may not mean much to the layperson, but cybersecurity folk may be nodding their heads in agreement. Bringing-your-own-PC security is exactly what it sounds like. Rather than a tech department issuing devices to workers with security features pre-installed, employees procure their own devices and then — hopefully — take all the necessary steps to ensure cloud-based connections are secure. A secure access service edge is a newer digital security theme that creates a networking environment that allows for, among other things, BYOPC.

In some regards, they’re the next step in the natural evolution of connectivity. Gartner may not be overstating things, however, when it suggests the two technologies “will have transformational impact on global businesses within the next 10 years.” In a post-COVID world, Gartner research director Rob Smith explains, “[Cyber] security leaders should expect the need to support BYOPC to be dependent upon a long-term work-from-home strategy, and also expect to support security tools needed for a BYOPC environment.”

In the same vein, technology market analytics outfit International Data Corp. (IDC) recently predicted that by 2024, 60% of the United States’ employees will work remotely — either at home or out in the field with customers and at project sites. That would push the total number of remote workers to more than 93 million, and subsequently expand the likelihood of cyberattacks.

Already ready

The cybersecurity industry isn’t starting from scratch, however. Both Palo Alto and Fortinet had remote connectivity protection available even before the pandemic took hold.

For Palo Alto Networks, one of those products is Prisma Access, which is a secure access service edge — or SASE — offering that Gartner suggests will become commonplace by 2030. It’s built specifically for mobile users and branch offices that need reliable, safe access to a corporate network. Palo Alto also offers cloud-based SD-WAN, or software-defined wide-area networking, with the help of recently acquired CloudGenix. It’s a testament to the potential of the right sort of dealmaking that allows for bolt-on improvements of the company’s existing capabilities.

As for Fortinet, it’s got a few tools in its mobile cybersecurity toolbox as well, like the FortiGate platform. Among other things, it’s a way of putting a firewall in place, managing virtual private networks that encrypt communications from devices all the way to a company’s servers, and implementing an intrusion prevention system. FortiGate customers also automatically have access to an SD-WAN solution for remote offices or remote employees, and the platform was a key part of last quarter’s growth.

These offerings aren’t exactly brand new, and more are apt to be on the way. What’s new is the sudden, true realization of the need for them. As Gartner’s Rob Smith noted: “Prior to the COVID-19 pandemic, there was little interest in BYOPC. At the start of the pandemic, organizations simply had no other alternative. The urgent need to enable employees to work from home and a lack of available hardware bolstered its adoption globally.” International Data Corp.’s senior research analyst Bryan Bassett expects that adoption has only begun, saying: “To meet the needs of more mobile, remote, and work-from-home workers, U.S. enterprises have indicated that mobile security and mobile management solutions will be top spending priorities going forward.”

Bottom line

While the bullish outlook for these companies is strong, would-be investors in either should note that the predictions from IDC and Gartner are long-term in nature. Gartner’s SASE adoption expectation could take up to 10 years to play out fully. International Data Corp.’s mobile worker outlook looks to the end of 2024. Investors not thinking in multi-year terms may find this opportunity isn’t for them.

Still, the opportunity is real for those willing to wait for it to fully gel. It’s long-term enough, in fact, that investors interested in plugging into it don’t necessarily have to do so today, this month, or even this year.

Emotet Botnet: A Primer for Cybersecurity and IT Pros

Published

on

By

With all that’s going on with COVID-19, work-from-home and economic contraction in the U.S. and globally, it’s easy for cybersecurity experts and other technologists to have missed that one of the most destructive malware strains made a surprise return in late July.

Emotet, a botnet with global reach, resurfaced on July 21 after a nearly five-month absence, according to multiple security firms, including Proofpoint and Malwarebytes. Since that time, researchers have recorded at least 800,000 spam messages associated with the malware in countries all over the world, including in the U.S., U.K., Canada, Austria, Germany, Brazil, Italy and Spain.

Waves of malware tend to come and go, but Emotet has developed a unique reputation over the years as it matured from banking Trojan to full-blown menace. When the U.S. Cybersecurity Infrastructure and Security Agency issued a warning about the botnet in January, the agency’s analysts warned about its destructive potential.

“Emotet continues to be among the most costly and destructive malware affecting [State, Local, Tribal, and Territorial] governments. Its worm-like features result in rapidly spreading network-wide infections, which are difficult to combat. Emotet infections have cost SLTT governments up to $1 million per incident to remediate,” stated the public CISA alert.

With the current Emotet campaign underway, analysts and experts warn that security and IT teams should be on the lookout for the malware and the possible destructive effects it could have on an enterprise. The campaign is also using the COVID-19 pandemic as a lure to get the unsuspecting to click on phishing emails that help power its spread.

“The campaigns usually include various payloads that have evolved over the years, primarily focused on stealing banking information or funds. Since the return of Emotet this summer, we’ve seen it using COVID-19 themes in the social engineering lures, as well as sending to recipients in a wide variety of countries,” Sherrod DeGrippo, senior director of threat research and detection at Proofpoint and well-known expert on Emotet, told Dice.

“The threat group behind Emotet is one that uses timely lures in campaigns that are truly massive in scale. In some Emotet campaigns we’ve seen over a million messages over the course of a few days,” DeGrippo added.

Emotet: A History

Emotet started life as a banking Trojan in 2014 that mainly stole financial and personal data. Over the next few years, however, the malware evolved into more of a botnet with the ability to infect multiple devices and expand its malicious network. Due to its modular nature, its creators have added new features as time went on, and it continues to evolve to this day.

In addition to the botnet, Emotet also has the ability to act as a dropper (or downloader) that can help plant other malware within a compromised device. In 2019, security experts found a triple threat: Emotet delivering another malware called TrickBot to infected endpoints, which would then download a ransomware variant called Ryuk.

These and other features are one of several reasons why warning bells ring whenever Emotet re-emerges. “Emotet is one of the most prolific malware families of the past five years. It has evolved from being specifically a banking Trojan into malware-as-a-service (MAS) with a distributed botnet infrastructure,” Jared Greenhill, director at Crypsis Group, an incident response and risk management firm, told Dice.

In the latest Emotet campaign that started in July, researchers have found that attacks start with a large-scale spam campaign that delivers phishing emails to as many victims as possible. The messages contain either a malicious attachment, a URL in the email body, or an attachment with a link. These attachments and links then deliver the initial malware infection, DeGrippo said.

If the link or attachment is opened, malicious macros are enabled that launch a PowerShell script that eventually installs Emotet within a compromised device. From there, Emotet can then download other malware. In the latest campaign, DeGrippo and others have found that it attempts to install Qbot—a banking Trojan that is known to infect financial institutions and their customers.

In some cases, the Emotet-laced message appears as part of an existing email chain, making it more likely that someone will click on the malicious link or attachments. These types of built-in social engineering techniques are a key reason why Greenhill recommends additional security training for employees to help spot this type of malware lurking in seemingly legitimate messages.

“One of the reasons Emotet is so effective is, like other types of threats, it begins with phishing tactics, and recent approaches have used brand names the recipient would be familiar with or subjects that have urgency, such as past-due notifications,” Greenhill said. “As we often see, much of the success of this malware begins with users making an error—opening a malicious attachment. A very important remedy to this is rigorous end-user training on spotting malicious emails, attachments, links, and senders, even if the sender appears legitimate.”

Fighting Back

While Emotet is more destructive than most other malware, it’s not impossible to fight back and protect people and data alike.

“People can best protect themselves against Emotet by implementing a strong antimalware program within their secure email gateway, in conjunction with user education that reinforces the risks posed by links and attachments,” DeGrippo said.

In its alert, CISA offers several ways to counter Emotet as well as other malware. These include:

Block: Organizations should block email attachments associated with malware, such as .dll and .exe files, as well as attachments that cannot be scanned by antivirus software, such as .zip files.

Implement: Organizations should implement programs such as antivirus programs and formal patch management processes. CISA also recommends implementing a Domain-Based Message Authentication, Reporting & Conformance (DMARC) validation system to cut down on spoofed emails.

Segment: Organizations should segment networks and functions to keep attacks from spreading across the network.

Limit: Finally, organizations should work to limit lateral movement throughout their network, which can reduce Emotet’s ability to move from device-to-device.

Others have found their own ways to fight back against Emotet. In August, James Quinn, an analyst with security firm Binary Defense, published a blog post that details how he found a “kill switch” in Emotet that helped reduce attacks earlier this year. That’s one of the reasons the botnet disappeared from the scene between February and late July.

Malware gang uses .NET library to generate Excel docs that bypass security checks

Published

on

By

A newly discovered malware gang is using a clever trick to create malicious Excel files that have low detection rates and a higher chance of evading security systems.

Discovered by security researchers from NVISO Labs, this malware gang — which they named Epic Manchego — has been active since June, targeting companies all over the world with phishing emails that carry a malicious Excel document.

But NVISO said these weren’t your standard Excel spreadsheets. The malicious Excel files were bypassing security scanners and had low detection rates.

Malicious Excel files were compiled with EPPlus

According to NVISO, this was because the documents weren’t compiled in the standard Microsoft Office software, but with a .NET library called EPPlus.

Developers typically use this library part of their applications to add “Export as Excel” or “Save as spreadsheet” functions. The library can be used to generate files in a wide variety of spreadsheet formats, and even supports Excel 2019.

NVISO says the Epic Manchego gang appears to have used EPPlus to generate spreadsheet files in the Office Open XML (OOXML) format.

The OOXML spreadsheet files generated by Epic Manchego lacked a section of compiled VBA code, specific to Excel documents compiled in Microsoft’s proprietary Office software.

Some antivirus products and email scanners specifically look for this portion of VBA code to search for possible signs of malicious Excel docs, which would explain why spreadsheets generated by the Epic Manchego gang had lower detection rates than other malicious Excel files.

This blob of compiled VBA code is usually where an attacker’s malicious code would be stored. However, this doesn’t mean the files were clean. NVISO says that the Epic Manchego simply stored their malicious code in a custom VBA code format, which was also password-protected to prevent security systems and researchers from analyzing its content.

But despite using a different method to generate their malicious Excel documents, the EPPlus-based spreadsheet files still worked like any other Excel document.

Active since June

The malicious documents (also called maldocs) still contained a malicious macro script. If users who opened the Excel files allowed the script to execute (by clicking the “Enable editing” button), the macros would download and install malware on the victim’s systems.

The final payloads were classic infostealer trojans like Azorult, AgentTesla, Formbook, Matiex, and njRat, which would dump passwords from the user’s browsers, emails, and FTP clients, and sent them to Epic Machengo’s servers.

While the decision to use EPPlus to generate their malicious Excel files might have had some benefits, in the beginning, it also ended up hurting Epic Manchego in the long run, as it allowed the NVISO team to very easily detect all their past operations by searching for odd-looking Excel documents.

In the end, NVISO said it discovered more than 200 malicious Excel files linked to Epic Manchego, with the first one dating back to June 22, this year.

NVISO says this group appears to be experimenting with this technique, and since the first attacks, they have increased both their activity and the sophistication of their attacks, suggesting this might see broader use in the future.

Nevertheless, NVISO researchers weren’t totally surprised that malware groups are now using EPPlus.

“We are familiar with this .NET library, as we have been using it since a couple of years to create malicious documents (“maldocs”) for our red team and penetration testers,” the company said.
