Apple on Wednesday rolled out software updates for iOS and iPadOS to remediate a persistent  denial-of-service (DoS) issue  affecting the HomeKit smart home framework that could be potentially exploited to launch ransomware-like attacks targeting the devices. The iPhone maker, in its  release notes  for iOS and iPadOS 15.2.1, termed it as a "resource exhaustion issue" that could be triggered when processing a maliciously crafted HomeKit accessory name, adding it addressed the bug with improved validation. The so-called "doorLock" vulnerability, tracked as CVE-2022-22588, affects HomeKit, the software API for connecting smart home devices to iOS applications. Should it be successfully exploited, iPhones and iPads can be sent into a crash spiral simply by changing the name of a HomeKit device to a string larger than 500,000 characters and tricking the target into accepting a malicious Home invitation. Even worse, since HomeKit device names are backed up to iClou

Follow this real-life network attack simulation, covering 6 steps from Initial Access to Data Exfiltration. See how attackers remain undetected with the simplest tools and why you need multiple choke points in your defense strategy. Surprisingly, most network attacks are not exceptionally sophisticated, technologically advanced, or reliant on zero-day tools that exploit edge-case vulnerabilities. Instead, they often use commonly available tools and exploit multiple vulnerability points. By simulating a real-world network attack, security teams can test their detection systems, ensure they have multiple choke points in place, and demonstrate the value of networking security to leadership. In this article, we demonstrate a real-life attack that could easily occur in many systems. The attack simulation was developed based on the MITRE ATT&CK framework, Atomic Red Team,  Cato Networks ' experience in the field, and public threat intel. In the end, we explain why a holistic secur

Self-described troll and Grey hat AT&T Hacker Andrew "Weev" Auernheimer, 26, has been sentenced to 41 months in prison for exploiting an AT&T security hole three years ago, and releasing thousands of iPad owners email addresses. According to authorities, they obtained the ICC-ID and e-mail address for about 120,000 iPad users. Each charge carried with it a potential prison terms of five years. He will serve 41 months in a federal prison, with concurrent probation for three years. He also owes restitution to the U.S. Treasury to be dispersed to AT&T in the amount of $73,000. In 2010, Auernheimer and Daniel Spitler, discovered that visiting an unsecured AT&T Web server and entering a number associated with the customer's wireless account allowed him to obtain that customer's email address. Computer security researcher Charlie Miller tweeted " We could all go to jail for security research at any moment, and a jury would happily convi

Image via Keeper Right Now, Get 50% Off Keeper, the Most Trusted Name in Password Management. In one way or another, almost every aspect of our lives is online, so it's no surprise that hackers target everything from email accounts to banks to smart home devices, looking for vulnerabilities to exploit. One of the easiest exploits is cracking a weak password. That's why using a strong, unique password for each individual account is so important. But creating and remembering strong, unique passwords for dozens of accounts is nearly impossible – unless you're using  a top-rated password manager like Keeper . The Problem With Weak Passwords Image via Keeper A strong password  should  be a minimum of 12 characters long, with uppercase and lowercase letters, numbers, and one or more special characters. More importantly, it shouldn't contain dictionary words or personal information like birthdays or names. But the average American has  100 passwords . Maybe that's why  66%  of people in

Samba has released software updates to remediate multiple vulnerabilities that, if successfully exploited, could allow an attacker to take control of affected systems. The high-severity flaws, tracked as  CVE-2022-38023, CVE-2022-37966, CVE-2022-37967, and CVE-2022-45141 , have been patched in versions 4.17.4, 4.16.8 and 4.15.13  released  on December 15, 2022. Samba is an open source Windows interoperability suite for Linux, Unix, and macOS operating systems that offers file server, printing, and Active Directory services. A brief description of each of the weaknesses is below - CVE-2022-38023  (CVSS score: 8.1) - Use of weak RC4-HMAC Kerberos encryption type in the  Netlogon Secure Channel   CVE-2022-37966  (CVSS score: 8.1) - An elevation of privilege vulnerability in Windows Kerberos RC4-HMAC CVE-2022-37967  (CVSS score: 7.2) - An elevation of privilege vulnerability in Windows Kerberos CVE-2022-45141  (CVSS score: 8.1) - Use of RC4-HMAC encryption when issuing Kerberos t

Another day, another data breach. This time a fast-fashion retailer has fallen victim to payment card breach. American clothes retailer Forever 21 announced on Tuesday that the company had suffered a security breach that allowed unknown hackers to gain unauthorized access to data from payment cards used at a number of its retail locations. The Los Angeles based company, which operates over 815 stores in 57 countries, didn't say which of its stores were affected, but it did note that customers who shopped between March and October this year may be affected. Forever 21 learned of the breach after the retailer received a report from a third-party monitoring service, suggesting there may have been "unauthorized access to data from payment cards that were used at certain FOREVER 21 stores." Besides this, the company also revealed that it implemented encryption and token-based authentication systems in 2015 that are intended to protect transaction data on its point-

The most popular free certificate signing authority Let's Encrypt is going to revoke more than 3 million TLS certificates within the next 24 hours that may have been issued wrongfully due to a bug in its Certificate Authority software. The bug, which Let's Encrypt confirmed on February 29 and was fixed two hours after discovery, impacted the way it checked the domain name ownership before issuing new TLS certificates. As a result, the bug opened up a scenario where a certificate could be issued even without adequately validating the holder's control of a domain name. The Certification Authority Authorization (CAA), an internet security policy, allows domain name holders to indicate to certificate authorities (CAs) whether or not they are authorized to issue digital certificates for a specific domain name. Let's Encrypt considers domain validation results good only for 30 days from the time of validation, after which it rechecks the CAA record authorizing t

" Ransomware " threat is on the rise, but the bad news is that Ransomware campaigns are easier to run, and now a Ransomware kit is being offered by hackers for free for anyone to download and distribute the threat. Ransomware is a type of computer virus that infects a target computer, encrypts their sensitive documents and files, and locks the out until the victim pays a ransom amount, most often in Bitcoins. Sometimes even the best security experts aren't able to unlock them and end up paying off ransom to crooks in order to get their important files back. Tox — Free Ransomware Kit Now, to spread this creepy threat more easily by even a non-tech user, one dark web hacker has released a ransomware-as-a-service kit, dubbed " Tox ," for anyone to download and set up their own ransomware for free. Yes, believe it or not, but Tox is completely free to use . The developers of the online software make money by taking a cut (20%) of any succes

Zeus Trojan is one of the most popular families of Banking Trojan, which was also used in a targeted malware campaign against a Salesforce.com customer at the end of the last month and researchers found that the new variant of Zeus Trojan has web crawling capabilities that are used to grab sensitive business data from that customer's CRM instance. 'GameOver' Banking Trojan is also a variant of Zeus financial malware that spreads via phishing emails. GameOver Zeus Trojan makes fraudulent transactions from your bank once installed in your system with the capability to conduct Distributed Denial of Service, or DDoS, attack using a botnet , which involves multiple computers flooding the financial institution's server with traffic in an effort to deny legitimate users access to the site. TAREGET - EMPLOYMENT WEBSITES Now, a new variant of GameOver Zeus Trojan has been spotted, targeting users of popular employment websites with social engineering attacks , implemented t

The Shadow Brokers who previously stole and leaked a portion of the NSA hacking tools and exploits is back with a Bang! The hacking group is now selling another package of hacking tools, " Equation Group Windows Warez ," which includes Windows exploits and antivirus bypass tools, stolen from the NSA-linked hacking unit, The Equation Group. For those unfamiliar with the topic, The Shadow Brokers is a notorious group of black-hat hackers who, in August 2016, leaked exploits, security vulnerabilities, and "powerful espionage tools" created by The Equation Group. On Saturday, the Shadow Brokers posted a message on their ZeroNet based website, announcing the sale of the entire " Windows Warez " collection for 750 Bitcoin (around US$678,630). The data dump contains many windows hacking tools, categorized as following: Fuzzing tools (used to discover errors and security loopholes) Exploit Framework Network Implants Remote Administration Tools (RAT) Remot

Web infrastructure company Cloudflare on Wednesday revealed that threat actors are actively attempting to exploit a  second bug  disclosed in the widely used Log4j logging utility, making it imperative that customers move quickly to install the latest version as a barrage of attacks continues to pummel unpatched systems with a variety of malware. The new vulnerability, assigned the identifier  CVE-2021-45046 , makes it possible for adversaries to carry out denial-of-service (DoS) attacks and follows disclosure from the Apache Software Foundation (ASF) that the original fix for the remote code execution bug — CVE-2021-44228 aka Log4Shell — was "incomplete in certain non-default configurations." The issue has since been addressed in Log4j version 2.16.0. "This vulnerability is actively being exploited and anyone using Log4j should update to version 2.16.0 as soon as possible, even if you have previously updated to 2.15.0," Cloudflare's Andre Bluehs and Gabriel

Google-owned Mandiant said it identified new malware employed by a China-nexus espionage threat actor known as UNC5221 and other threat groups during post-exploitation activity targeting Ivanti Connect Secure VPN and Policy Secure devices. This includes custom web shells such as BUSHWALK, CHAINLINE, FRAMESTING, and a variant of  LIGHTWIRE . "CHAINLINE is a Python web shell backdoor that is embedded in a Ivanti Connect Secure Python package that enables arbitrary command execution," the company  said , attributing it to UNC5221, adding it also detected multiple new versions of  WARPWIRE , a JavaScript-based credential stealer. The infection chains entail a successful exploitation of  CVE-2023-46805 and CVE-2024-21887 , which allow an unauthenticated threat actor to execute arbitrary commands on the Ivanti appliance with elevated privileges. The flaws have been abused as zero-days since early December 2023. Germany's Federal Office for Information Security (BSI)  said

Almost every application contains security vulnerabilities, some of which you may find today, but others would remain invisible until someone else finds and exploits them—which is the harsh reality of cybersecurity and its current state. And when we say this, Signal Private Messenger —promoted as one of the most secure messengers in the world—isn't any exception. Google Project Zero researcher Natalie Silvanovich discovered a logical vulnerability in the Signal messaging app for Android that could allow malicious caller to force a call to be answered at the receiver's end without requiring his/her interaction. In other words, the flaw could be exploited to turn on the microphone of a targeted Signal user's device and listen to all surrounding conversations. However, the Signal vulnerability can only be exploited if the receiver fails to answer an audio call over Signal, eventually forcing the incoming call to be automatically answered on the receiver's device

Two attackers were more than 100,000 e-mail users Apple iPad, including politicians and famous journalists, federal prosecutors said Tuesday notifying the prosecution of men. AT & T has revealed a vulnerability of months ago, and U.S. Attorney Paul Fishman said there was evidence that the two men have used the information obtained for criminal purposes. Authorities warned, however, that information can be dissolved in the hands of spammers and scammers. Daniel Spitler, a guard from the library 26-year-old from San Francisco and Andrew Auernheimer, 25, of Fayetteville, Ark., is accused of fraud and conspiracy to access a computer without authorization. Fishman characterizes men and their cohorts that participation in a "malicious upsmanship, as they sought to impress others and others in the online community. "We do not tolerate crimes committed for street cred," said Fishman. "Hacking is not a competitive sport, and security breaches is not a game."

A malware campaign has been found targeting iOS devices linked to a wide range of entities, including European defense organizations, governments, and media sectors with dangerous espionage spyware capable of breaching non-jailbroken devices, a recent report claims. The spyware campaign, dubbed " Operation Pawn Storm " by security experts, was first detected on Windows computers late last year, but has now made its way to iOS devices , a report by security researchers at TrendLabs noted. The researchers linked the campaign to the Russian government. XAGENT SPYWARE APP One of the two spywares used in the campaign is actually an application, the firm dubbed the app XAgent, that attempts to install and run on iOS devices. " The XAgent app is fully functional malware ," the researchers noted . " The exact methods of installing these malware is unknown; however, we do know that the iOS device doesn't have to be jailbroken ... We have seen one in

Discovered the biggest Facebook phishing in French Two Days before we publish that Geeks at Security Web-Center Found 25 Facebook phishing sites. Security Web-Center found another biggest Facebook phishing site in French which steal more then 5000 usernames and passwords, using the fake domain www.frfacebook.fr to scam the victims. All phished passwords are stored here Security Web-Center suggests that potential victims: Change all exposed passwords; Contact the company or organization that was being spoofed (Facebook, in this case); Alert it that your personal information was exposed; Ask it to cancel any accounts affected (Note: We don't recommend this for Facebook, obviously, but view it more as a general tip); and If the information provided can be used to access other institutions, such as credit-card companies, contact them, as well.

Banks have tried every effort, from providing Magnetic Stripes based Credit and Debit Cards to Chip-and-Pin Cards , in order to secure its users from credit card cloning and card Skimmers. It has been known from years that Magnetic stripe are incredibly hackable, but  Chip-n-Pin cards have also been hacked and successfully cloned by a group of security researchers. A unit of Canada's Bank of Montreal, BMO Harris Bank is  launching  the U.S.'s biggest cardless ATM network that allows its customers to withdraw cash within seconds, using nothing but their smartphones. NO CARD, NO PIN, JUST YOUR SMARTPHONE According to the bank, there is no need to enter PIN and instead of swiping the card, customers have to sign into mobile banking app " Mobile Cash ", hold their smartphones over the QR code on the ATM screen and the cash gets delivered. This cardless cash withdrawal technology will boost security, speed up transactions and reduce frauds because no card informat

Have to lose $ 2? Then you can buy a stolen credit if you pay in advance and in cash. Or start your own spam campaign by hiring a botnet, with prices starting at $ 15 and up slightly if you want VPN access to control panel botnet for greater anonymity. It says "Black Market Cybercrime: uncovered," the report released Thursday the security software maker Panda Software. Overall, security company has found a thriving black market for stolen data, and provides the tools for an attack. "The credit card can be purchased for as little as $ 2 per card, but this level does not provide additional information or check account balance available," said the report's author, Luis Corrons, technical director of Panda Security. "If the buyer wants a guarantee for the available line of credit account or a bank, the price rises to $ 80 for balances of smaller banks and more than $ 700 for access to accounts with a balance of $ 82,000 guaranteed."

Last month the popular torrent website The Pirate Bay caused some uproar by adding a Javascript-based cryptocurrency miner to its site with no opt-out option, utilizing visitors' CPU power to mine Monero coins in an attempt to gain an extra source of revenue. Now D-Link has been caught doing the same, although there's high chance that its website has been hacked. D-Link's official website for Middle East (www.dlinkmea.com) has been found secretly adding a JavaScript-based cryptocurrency miner, according to a blog post published by security firm Seekurity on Tuesday. Seekurity team was made aware of the issue after Facebook user Ahmed Samir reported that visiting on D-Link Middle East website caused his web browser utilizing a "super high CPU" power usage. As shown in the screenshot below, a separate domain was loaded using a hidden iFrame for each page view, which included the cryptocurrency mining script. Five days after Seekurity team reported th

A Google developer helps Apple to fixed a security flaw in its application store that for years has allowed attackers to steal passwords and install unwanted or extremely expensive applications. Security loophole allowed attacker to hijack the connection, because Apple neglected to use encryption when an iPhone or other mobile device tries to connect to the App Store. Researcher Elie Bursztein revealed on his blog that he had alerted Apple of numerous security issues last July but that Apple had only turned on HTTPS for the App Store last week. An attacker only needs to be on the same network as the person who is using the App Store. From there, they can intercept the communications between the device and the App Store and insert their own commands. The malicious user could take advantage of the unsecure connection to carry out a number of different attacks i.e steal a password, force someone to purchase an app by swapping it with a different app that the buyer actually intende
