efani – A Comprehensive Guide on Silent SMS Denial of Service (DoS) Attack

When delivered to a mobile handset, silent messages, also known as Silent SMS or Stealth SMS “stealth ping”, or “Short Message Type 0”, are not indicated on the display or by an acoustic alert signal. This guide will concentrate on the technicalities of sending a silent SMS, as well as sending multiple incessant silent SMSs to perform a silent SMS denial of service (DoS) attack. These silent messages are increasingly being sent not only to perform DoS attacks but also to force the constant update of users’ or victims’ location (tracking) information.

What is Silent SMS or Flash SMS?

Silent SMS was originally intended to allow operators to detect whether a mobile phone was turned on and test the network without informing the user. They have, however, proven useful in the tracking down of suspects by police in a number of countries.

Using the GSM Network, silent SMS can pinpoint the exact location of a mobile phone. We can find a user by identifying the three antennas closest to him and then triangulating the distance based on the time it takes for a signal to return. When a person moves, their phone’s location is updated; however, the information is not updated immediately. The location of the mobile is instantly updated when a Silent SMS is sent. This is extremely useful because it allows you to locate someone at a specific time based on the airwaves.

ICYMI – In cellular communication networks, the SS7 (Signaling System No. 7) protocols are critical. Unfortunately, SS7 has a number of flaws that a malicious actor can exploit to launch attacks. Location tracking, SMS interception, and other types of signaling attacks are significant examples of these.

[TIP: EFANI’s Black Seal Protection against such hacks such as SS7, location tracking, DDoS, Silent SMS, IMSI Catchers and so on]

The Silent SMS Denial of Service (DoS) attack is one of the more intriguing attacks. A typical DoS attack floods a network with excessive traffic, rendering its computer resources inaccessible to users. The same concept applies to mobile devices.

The Silent SMS Denial of Service (DoS) attack is one of the more intriguing attacks. A typical DoS attack floods a network with excessive traffic, rendering its computer resources inaccessible to users. The same concept applies to mobile devices. Without the victim’s knowledge, a device can be flooded with silent SMS messages. Texts swamping the victim’s device will utilize the battery abnormally while preventing the device from receiving calls.

Targets Location Tracking

Malefactors who exploit SS7 protocol vulnerabilities frequently target location information and tracking. A silent SMS could be sent to the target mobile device to force it to update the existing (normally the closest) serving base station onto the mobile network in order to identify the target’s location.

The device user will not be notified if a message is received, as in a Silent SMS DoS attack. However, unlike a DoS attack, there are no visible signs that an attack is taking place. As a result, the victim is completely unaware that they are being followed.

SIM cards are also a major target because they use Wireless Internet Browsers (WIB), that are not adequately secured. Telecommunications companies use Over the Air (OTA) technology to communicate with WIBs in order to manage SIM cards.

Evil people can essentially send a silent SMS containing WIB instructions. The instructions are executed once they have been received on the victim’s device. At this point, the malefactor has several options, including obtaining location data, initiating a call, sending an SMS, or even launching a web browser with a particular URL.

The Culprit: Who is behind the Silent SMS attacks?

Though it has reportedly been used by authorities and governments in the past, the decreasing costs of equipment and broadband access have made this attack vector accessible to malefactors with little technical knowledge.

Why are silent SMS attacks so risky?

Cellular attacks that take advantage of the SS7 protocol are nothing new. However, due to the covert nature of silent SMS attacks, it is difficult to detect them before it is too late. As a result, silent SMS attacks are a compliance nightmare. A breach cannot be detected and, as a result, cannot be reported in accordance with the law. Invisible DoS attacks, OTA malware, and unauthorized location tracking are all dangerous, if not disastrous.

It is incumbent to bring this to readers’ attention that not only SS7 attacks are next to impossible to detect when they take place, but they also leave practically no traces in terms of forensics. The forensic investigator has little to no data to extract and analyze from the victim’s device.

This is, of course, unless the victim has an application on their mobile devices that is specifically supposed to detect and triangulate silent SMS.

The investigator may be able to examine the traffic on the cellular network and possibly detect the unprecedented number of messages sent. Sadly, the investigator must have the victim’s mobile in hand to confirm a real-time attack.

Who is vulnerable to a Silent SMS attack?

It is not critical for most users to have their location tracked or to lose wireless access due to a DoS attack. Attackers are most likely to target executives, VIPs, celebrities, crypto enthusiasts, and governments.

Attacks will almost certainly result in significant financial losses for enterprises, whereas national defense is at stake for governments. They must also consider the possible harm that could be accomplished if an attacker is able to install malware on the device by exploiting WIB vulnerabilities on SIM cards.

The much-needed protection

The one and only effective way to identify and prevent such attack vectors is at the network level (speaking of mobile here). This necessitates the use of EFANI’s Black Seal Protection aimed at “plugging” the security vulnerabilities left by the primitive SS7 protocol, which is still in use presently.

Currently, most of the defense against silent SMS DoS attacks is left to individuals (going through such emotional stress) and cybersecurity professionals in companies, who (unfortunately) have little or no tools to do so. For telecom companies since this pandemic means taking a global approach to SS7 protection. It thus necessitates the implementation of appropriate safeguards and security mechanisms to prevent their networks and registered user devices from such hacks.

Unfortunately, traditional cell phone companies are not doing much to protect you. But it is not all bad news, there is a cellular phone company named efani that has stepped up and made it more difficult for hackers. efani offers the nation’s most secure mobile service and claims a 100% success rate.

What Is SIM Hacking?
SIM hacking is when a person gets their hands on a new SIM card that’s tied to you. Here’s how they typically operate:

The hacker contacts your mobile provider and requests a new SIM without your permission.

The operator asks questions to verify your identity, which the hacker has obtained from the recent data breach, dark web, or other sources.

Once the hacker has gained control over your SIM/Phone number they can gain access to all of your personal and financial accounts. We are talking about banking accounts, stock accounts, and all of your social media accounts.

SIMSwap.us | Jack Dorsey Twitter (TWTR) CEO Quits Immediately

Twitter CEO Resigns, Jack SIMSwap attacked again?

In his resignation letter, Dorsey said being a founder-led company is ‘severely limiting and a single point of failure.

Jack Dorsey stepped down as CEO of Twitter the social media giant he co-founded in 2006.

Why? In a resignation letter posted on Twitter, Dorsey wrote, “There’s a lot of talk about the importance of a company being ‘founder-led.’ Ultimately, I believe that’s severely limiting and a single point of failure. I’ve worked hard to ensure this company can break away from its founding and failures.”

Dorsey also is the chief executive of the financial and digital payments company Square. Jack’s leadership has been questioned by employees and investors who believed that he was unfocused and spent too much of his time on Square and other passion projects. His departure comes a year and a half after Mr. Dorsey survived an attempted ouster from the activist investor Elliott Management. Chief among Elliott’s concerns was that Mr. Dorsey’s attention was divided between the two companies he led. The firm believed that Twitter had fallen behind social media rivals in increasing its stock price and adding innovative new products.”

In his resignation letter to employees, Dorsey wrote, “I want you all to know that this was my decision and I own it. It was a tough one for me, of course. I love this service and company … and all of you so much. I’m really sad … yet really happy. There aren’t many companies that get to this level. And there aren’t many founders that choose their company over their own ego. I know we’ll prove this was the right move.”

Parag Agrawal, Twitter’s current chief technology officer, will replace Dorsey as the top executive. In a note to staff, Agrawal said he was “honored and humbled” that Dorsey chose to run the company.

Panasonic (PCRFY) discloses 4 months long data breach

Japanese electronics giant Panasonic has disclosed on Friday a major security breach after an unidentified threat actor had gained access to its internal network.

The Osaka-based company said it detected the security breach earlier this month, on November 11.

“As the result of an internal investigation, it was determined that some data on a file server had been accessed during the intrusion,” the company said in a short statement published on Friday.

But while no other details were provided, Japanese news outlets like Mainichi and NHK managed to find out more details about the intrusions, including the fact that attackers managed to gain access to sensitive information such as customer details, employee personal information, Panasonic technical files from the company’s domestic operations.

The two news outlets said the hacker(s) had access to the company’s server for more than four months, from June 22 to November 3, before being discovered by the company following abnormal network traffic.

No other details are currently available, but over the past three years, almost all of Japan’s big tech firms had suffered network intrusions at the hands of Chinese state-sponsored espionage groups, which, while unconfirmed for now, remain the main suspects in this incident too.

efani | Hackers Mine Cryptocurrency Alphabet Inc. (GOOG) GCA

Hackers Using Compromised Google Cloud Accounts to Mine Cryptocurrency

Threat actors are exploiting improperly-secured Google Cloud Platform (GCP) instances to download cryptocurrency mining software to the compromised systems as well as abusing its infrastructure to install ransomware, stage phishing campaigns, and even generate traffic to YouTube videos for view count manipulation.

“While cloud customers continue to face a variety of threats across applications and infrastructure, many successful attacks are due to poor hygiene and a lack of basic control implementation,” Google’s Cybersecurity Action Team (CAT) outlined as part of its recent Threat Horizons report published last week.

Of the 50 recently compromised GCP instances, 86% of them were used to conduct cryptocurrency mining, in some cases within 22 seconds of a successful breach, while 10% of the instances were exploited to perform scans of other publicly accessible hosts on the Internet to identify vulnerable systems, and 8% of the instances were used to strike other entities. About 6% of the GCP instances were used to host malware.

In most cases, the unauthorized access was attributed to the use of weak or no passwords for user accounts or API connections (48%), vulnerabilities in third-party software installed on the cloud instances (26%), and leakage of credentials in GitHub projects (4%).

New Fortnite Chapter 3 Leaked | efani Partner TheNFG.com

New Fortnite Chapter 3 the leak has appeared online before the next chapter of the game and a major season-end 8 event that transforms the free-to-play Battle Royale game. Unfortunately, the leak isn’t as exciting as some of the other leaks in Chapter 3, but it’s said to reveal the next flying animals coming into the game, and it’s an animal that Epic Games has bullied before.

The leak will be on the most prominent road on the Internet Fortnite leak and data mining, HypeX, which has also relayed reports in the past and has proven to be a reliable and reputable process. On Twitter, HypeX noted that logs are coming into play with Chapter 3 alongside the tropical / beach area. However, the leaker does not know when this will happen during Chapter 3, although they seem to think it will happen during Season 1.

“Chapter 3 logs as the next flying animals,” said HypeX. “They’re in one of the Chapter 3 concept arts near the tropical / beach area, but I don’t know exactly when they’ll be released, probably season 1.”

As always, take everything here with salt. While that source is good, it doesn’t rule out the fact that this is all unofficial. In addition, even if this unofficial information is correct, it may also change. At the time of release, Epic Games has not addressed any of these. We don’t expect it to do it for many reasons, but if it meets expectations and responds in any way, the story will be updated accordingly.

Fortnite is available through Nintendo Switch, Mobile Devices, PC, PS4, PS5, Xbox One, Xbox Series S, and Xbox Series X.

SIM Swap Scams: How to Protect Yourself from Hackers

Personal Identity Theft and Data security are on the rise. We all seem to take our data security for granted these days, trusting the “big corporations” to protect us. Sadly, we are all at risk. We all have one, use one, and take it everywhere we go, it is called a cell phone or mobile phone. Some say it is an appendage of our body like an arm, leg, or hand. People just cannot imagine life without their phones. Your whole world is reliant on your phone.

Everything from your Twitter, Facebook, LinkedIn, TikTok, and all your other Social Media. Let’s face it, can you go a day let alone a week without it? Likely not. Why? Because all of our life is “secured” by our phones through what is known as two-factor authentication or 2FA. In theory, this secures your account from hackers and “bad actors” that want to cause you harm and steal your life savings from your brokerage account, bank account, or Crypto account.

We have seen data leaks, data breaches, and massive hacker attacks on what we once thought were impenetrable networks and companies. The list is long and includes household names like Facebook, T-Mobile. Here is a list of some of the biggest

1. Yahoo

Date: August 2013
Impact: 3 billion accounts

2. Alibaba

Date: November 2019
Impact: 1.1 billion pieces of user data

3. LinkedIn

Date: June 2021
Impact: 700 million users

4. Facebook

Date: April 2019
Impact: 533 million users

5. Marriott International (Starwood)

Date: September 2018
Impact: 500 million customers

6. Yahoo (again)

Date: 2014
Impact: 500 million accounts

7. Adult Friend Finder

Date: October 2016
Impact: 412.2 million accounts

8. T-Mobile

Date: August 2021
Impact: 54 million accounts

9. Cam4

Date: March 2020
Impact: 10.8 billion records

The breached records included the following

:

  • Full names
  • Email addresses
  • Sexual orientation
  • Chat transcripts
  • Email correspondence transcripts
  • Password hashes
  • IP addresses
  • Payment logs

Many of the exposed email addresses are linked to cloud storage services. If hackers were to launch successful phishing attacks on these users, they could gain deeper access to personal photos and business information.

 

Your cellphone could provide a way for cybercriminals to access your financial accounts.

How does this fraud happen? Through your mobile number.

The fraud is known as a SIM Swap, SIM swapping, SIM hacking, or SIM jacking, and it can be used to take over your financial accounts and wreak havoc over your entire life. SIM swapping relies on phone-based authentication. In a successful SIM swap scam, cybercriminals could hijack your cell phone number and use it to gain access to your sensitive personal data and accounts.

Here’s how it works. You might try to access one of your bank accounts that use text-based two-factor authentication. That means you begin to access your account by entering your user name and password. Your bank then sends an access code to your cellphone for you to complete the log-in process.

But what if fraudsters are able to change the SIM card connected to your mobile number? That would give them control over that number — and they’d receive the access code to your account.

It’s a good idea to learn about SIM card swapping. That way you can help protect yourself against this type of fraud — or recognize if you’ve become a victim.

Robinhood Markets, Inc. (NASDAQ: HOOD) Implications

Robinhood’s Data Breach Could Have Far-Reaching Financial Implications

Robinhood Markets, Inc. (NASDAQ: HOOD) shares have lost roughly half their value since early August. For many stocks, such a correction could suggest a buying opportunity, but other considerations, including the ongoing and very real threat of data breaches and a still sky-high valuation, suggest that investors should continue to exercise caution.

The highly-publicized November 3 hacking incident whereby criminals stole the email addresses of five million Robinhood users, the full names of two million others, and more complete data (name, DOB, and zip code) from 310 users, is an embarrassing breach. Moreover, the hacker is apparently trying to sell the information on the dark web, according to various news services The computer thief alleges the information stolen was richer in quality than Robinhood admitted. (The hacker says the complete personal information for 310 people is not presently for sale.)

The breach highlights perhaps an even more concerning issue for Robinhood.
