No, criminals are not in love with VPNs, expert insists

Jul 05, 2023

Millions of malicious IP addresses are analyzing the internet daily in an attempt to find security holes in networks.

CrowdSec has recently released a Majority Report looking into the landscape of malicious behavior. The company analyzed data on internet protocol (IP) addresses identified as malicious, and It turns out that the lion’s share of malicious activity is coming from Russia, the US, and India. In each of these countries, 1M+ IP addresses were reported as malicious.

However, CrowdSec emphasized that this number doesn’t necessarily represent the nationality of the attacker but rather a “localization” of a compromised asset.

So, what sort of activity are these malicious IPs conducting?

The majority of malicious activity is attributed to scanning. It means precisely that – a threat actor is actively scanning the internet looking for various flaws they could exploit for unauthorized access, DDoS, or any other type of attacks. We’ve witnessed such exploitation parties with the public disclosure of Log4j or MS Exchange vulnerabilities in the past.

Nearly 60% of malicious IP addresses engage in scanning, while over 23% are trying to exploit known vulnerabilities. CrowdSec believes that this is the most dangerous threat you might encounter.

Brute force is the third most common threat, with threat actors going after the most common and weak passwords – usually set by default.

With the high adoption of IPv6 (Internet Protocol version 6), cybersecurity pundits have started registering increased new threats linked to IPv6 addresses. 20% of reported IPs are now linked to IPv6. Interestingly, the number went up to 35% between May and June, coinciding with the increase in mass scanning.

Interestingly enough, despite concerns that criminals rely on VPNs to throw law enforcement off track, the company said that it’s not really the case.

“VPN’s rise in popularity over the past few years sounded the alarm to many organizations. The joint action by Europol and ten other countries in January 2022 to take down VPNLab.net – a VPN provider whose services were being used in support of serious criminal acts – seemed to reinforce the concern that VPNs are a convenient tool for cybercriminals,” the report reads.

CrowdSec data shows that only 5% of reported IP addresses are flagged as VPN or proxy users.

Security Lapse by Microsoft Employees Exposes Internal Passwords

26 Apr, 2024
In continuation of Microsoft’s series of data security incidents, employees accidentally exposed internal data to the public. The leak exposed an unprotected Azure storage server containing code, scripts, and configuration files. Microsoft has announced that it has fixed a security breach that exposed internal company credentials and files to the open internet. The breach was first discovered by security researchers from cybersecurity firm SOC Radar. According to their report, an internal error resulted in an Azure storage server without password protection being given public access. The exposed data was primarily related to Microsoft’s Bing search engine, including configuration files, code, and scripts that employees used to access a range of internal systems and databases. Consequently, bad actors could identify and access locations for Microsoft's internal data. So far, it has not been made clear how long the data has been exposed.

AT&T experienced data breach that impacted 51 million customers (No one is immune)

26 Apr, 2024
AT&T is notifying 51 million former and current customers, warning them of a data breach that exposed their personal information on a hacking forum. However, the company has still not disclosed how the data was obtained. These notifications are related to the recent leak of a massive amount of AT&T customer data on the Breach hacking forums that was offered for sale for $1 million in 2021. When threat actor ShinyHunters first listed the AT&T data for sale in 2021, the company told BleepingComputer that the collection did not belong to them and that their systems had not been breached. Last month, when another threat actor known as 'MajorNelson' leaked the entire dataset on the hacking forum, AT&T once again told BleepingComputer that the data did not originate from them and their systems were not breached. After BleepingComputer confirmed that the data belonged to AT&T and DirectTV accounts, and TechCrunch reported AT&T passcodes were in the data dump, AT&T finally confirmed that the data belonged to them. While the leak contained information for more than 70 million people, AT&T is now saying that it impacted a total of 51,226,382 customers. "The [exposed] information varied by individual and account, but may have included full name, email address, mailing address, phone number, social security number, date of birth, AT&T account number and AT&T passcode," reads the notification. "To the best of our knowledge, personal financial information and call history were not included. Based on our investigation to date, the data appears to be from June 2019 or earlier." BleepingComputer contacted AT&T as to why there is such a large difference in impacted customers and was told that some of the people had multiple accounts in the dataset. "We are sending a communication to each person whose sensitive personal information was included. Some people had more than one account in the dataset, and others did not have sensitive personal information," AT&T told BleepingComputer. The company has still not disclosed how the data was stolen and why it took them almost five years to confirm that it belonged to them and to alert customers. Furthermore, the company told the Maine Attorney General's Office that they first learned of the breach on March 26, 2024, yet BleepingComputer first contacted AT&T about it on March 17th and the information was for sale first in 2021. While it is likely too late, as the data has been privately circulating for years, AT&T is offering one year of identity theft protection and credit monitoring services through Experian, with instructions enclosed in the notices. The enrollment deadline was set to August 30, 2024, but exposed people should move much faster to protect themselves. Recipients are urged to stay vigilant, monitor their accounts and credit reports for suspicious activity, and treat unsolicited communications with elevated caution. For the admitted security lapse and the massive delay in verifying the data breach claims and informing affected customers accordingly, AT&T is facing multiple class-action lawsuits in the U.S. Considering that the data was stolen in 2021, cybercriminals have had ample opportunity to exploit the dataset and launch targeted attacks against exposed AT&T customers. However, the dataset has now been leaked to the broader cybercrime community, exponentially increasing the risk for former and current AT&T customers.
