A critical vulnerability affects millions of email servers. A fix has been released but this flaw affects more than half of the Internet's <a href="http://www.hackerschronicle.com/search/label/Email">email servers</a>, and patching the issue will take a couple of days. 
 
The vulnerability in <a href="http://www.hackerschronicle.com/search/label/Exim">Exim, a mail transfer agent</a> (MTA) —software that runs on email servers and which relays emails from senders to recipients.According to a survey conducted in March 2018, 56% of all of the Internet's email servers run Exim, with over 63,36,687 available online at the time.

A Taiwanese security researcher named Meh Chang discovered the bug, which he <a href="https://devco.re/blog/2018/03/06/exim-off-by-one-RCE-exploiting-CVE-2018-6789-en/">reported</a> to the Exim crew on February 2. The Exim team released Exim distribution 4.90.1 on February 10 that fixes the RCE issue. 
 
The bug —tracked as CVE-2018-6789 is categorized as a "pre-auth <a href="http://www.hackerschronicle.com/search/label/Remote%20Code%20Execution">remote code execution</a>," meaning an attacker could trick the Exim email server into running malicious commands before the attacker would need to authenticate on the server. 
 
The actual bug is a one-byte buffer overflow in the base64 decode function of Exim and affects all Exim versions ever released. Chang described the bug in a blog post released earlier today, detailing basic steps for exploiting Exim's SMTP daemon. 
 
In a security advisory, the Exim team publicly acknowledged the issue. "Currently we're unsure about the severity, we believe, an exploit is difficult. A mitigation isn't known," the <a href="https://exim.org/static/doc/security/CVE-2018-6789.txt">Exim team said</a>. 
 
Since Exim 4.90.1's release, updated Exim versions have trickled down to Linux distros used primarily in data centers, but the question remains about the number of unpatched systems that remain online. Taking into account that Exim is by far the most popular mail agent, CVE-2018-6789 opens a large attack surface, and Exim server owners should look into deploying the Exim 4.90.1 update as soon as possible. 
 
At the time of writing, there is no public exploit code for taking advantage of vulnerable Exim servers, but this will likely change in the days following Chang's blog post.

More than 40 models of low-cost Android smartphones are sold already infected with the Triada banking trojan, says Dr.Web, a Russia-based antivirus vendor. The security vendor published today a list of 42 Android models its researchers analyzed and found to be infected with the Android.Triada.231 trojan. 
 
<a href="http://www.hackerschronicle.com/search/label/Triada" target="_blank">Triada </a>is a very powerful Android banking trojan discovered in early 2016. It can root devices and then infect Zygote, a core <a href="http://www.hackerschronicle.com/search/label/Android" target="_blank">Android operating system</a> process, where it's almost impossible to remove without wiping the entire device and reinstalling the OS. Dr.Web says it found the trojan on newly shipped devices from lesser-known brands —mostly based in China— such as Leagoo, Doogee. Vertex, Advan, Cherry Mobile, and others.

"The <a href="http://www.hackerschronicle.com/search/label/Malwares" target="_blank">malware </a>is present in the devices which are sold not only in Russia but globally," a Dr.Web spokesperson told Bleeping Computer earlier today via email. "For instance, in Poland, Indonesia, China, the Checz Republic, Mexico, Kazakhstan and Serbia." 
 
Dr.Web's recent discovery isn't new, but it's a continuation of previous research. Back in July 2017, researchers found the same Triada trojan on four low-cost Android smartphone models —Leagoo M5 Plus, Leagoo M8, Nomu S10, and Nomu S20. Researchers continued to look into the matter and eventually discovered 42 smartphone models that were coming with malware pre-installed out of the box. 
 
Experts say that their discovery over the summer didn't deter whoever was behind this action to stop. For example, they found Triada pre-installed on Leagoo M9 phones, a model launched in December 2017. 
 
The antivirus vendor says it contacted all affected vendors, believing one of their shared resellers was injecting the trojan before shipping devices forward. Instead, researchers figured out that a software developer from Shanghai was most likely the source of the Triada infection. 
 
"This company provided Leagoo with one of its applications to be included into an image of the mobile operating system, as well as with an instruction to add third-party code into the system libraries before their compilation," researchers say. "Unfortunately, this controversial request did not evoke any suspicions from the manufacturer. Ultimately, Android.Triada.231 got to the smartphones without any obstacles." 
 
Researchers say this Triada-infected application developed by the Shanghai company was signed with the same certificate that was seen in another malware infection, in November 2016 —an Android app with over 1 million downloads on the Google Play Store that was infecting users with the Android.MulDrop adware. 
 
In the end, this is just another case when users suffer the consequences of companies that fail to validate their software supply chain.

Over four thousand high profile government websites have been compromised by <a href="http://www.hackerschronicle.com/search/label/Dark%20Web" target="_blank">dark web</a> hackers across the globe, mining virtual currency secretly, and particularly Monero. 
 
<a href="http://www.hackerschronicle.com/search/label/Monero" target="_blank">Monero </a>has become one of the popular cryptocurrency recently especially on the ‘<a href="http://www.hackerschronicle.com/search/label/Dark%20Web" target="_blank">dark web</a>’– a section of the internet that can only be accessed using a special browser which is capable of anonymizing your browsing location as well as identity. Dark web criminals are taking advantage of this anonymity by trading illegal commodities, substances and services using virtual currencies. 
 
4,275 websites including those in the U.K., the U.S., Ireland, Australian and Canada with government websites with hundreds of thousands of visitors were hacked in less than a period of four hours and unwittingly mined for <a href="http://www.hackerschronicle.com/search/label/Cryptocurrency" target="_blank">cryptocurrency </a>exploiting a security breach. Some of the compromised websites include the United States courts online portal, the United States Information Commissioner Office; the National Health Service in the United Kingdom and the Victorian Parliament website in Australia. The attack by a cryptojacking code hit common websites which had the text-to-speech accessibility script Browsealoud for the visually impaired from Texthelp company. 
 
Recently, Monero has grown in popularity with a market capitalization of $4 billion. Its privacy feature has contributed to its momentum on the dark web making it harder to track compared to bitcoin. 
 
The prices of virtual currency in the market skyrocketed recently and as a scheme that has drawn the attention of criminals. <a href="http://www.hackerschronicle.com/search/label/Cyber%20Crime" target="_blank">Cybercrimes </a>increased especially on cryptocurrency as criminals tried to cash in on the skyrocketing crypto prices. The cybercrime industry is recently believed to be overtaking the illegal drug trafficking industry in terms of revenue and hence attracting criminals. 
 
The hacking process involved insertion of a <a href="http://www.hackerschronicle.com/search/label/Malwares" target="_blank">malicious </a>code that takes over a portion of a victim’s computer and central processing. Therefore the hacker has the ability of opening a website using a browser in order to mine virtual currency. 
 
The process of mining digital coins requiring less processing power such as Monero is much easier compared to mining bitcoin from websites as it requires powerful specialized computers and software, making Monero mining a better fit for saving on time and energy, making it a very attractive option to criminals. 
 
The dark web hackers had an easier time as they did not compromise each of the 4,275 websites at once, but rather hacked a globally-used plugin named ‘Browsealoud’ which is capable of reading out text from websites for the blind. 
 
After the Browsealoud code was hacked, CoinHive’s Monero miner was silently and secretly injected. Thereafter, any website using the Browsealoud plugin was automatically compromised. 
 
However the cyber-attack was deemed successful as there were basic regulatory measures and requirements over accessibility of some of these government websites that have not been met.</div>

On Wednesday, developer repository site <a href="http://www.hackerschronicle.com/search/label/GitHub" target="_blank">GitHub </a>was hit with a critical DDoS attack that took the site offline multiple times for a few minutes each time. According to a GitHub incident report, the first portion of the attack against the developer platform peaked at 1.35Tbps, and there was a second 400Gbps spike later. This would make it the biggest <a href="http://www.hackerschronicle.com/search/label/DDoS" target="_blank">DDoS </a>attack recorded so far. Until now, the biggest clocked in at around 1.1Tbps.

According to the <a href="https://githubengineering.com/ddos-incident-report/" target="_blank">incident report</a>, GitHub was offline Wednesday from 17:21 to 17:26 UTC and intermittently unavailable from 17:26 to 17:30 UTC, thanks to the attack. The report noted that user data wasn't at risk during the attack. 
 
The GitHub attack is the latest in a string of incidents where hackers have exploited a vulnerability in the <a href="http://www.hackerschronicle.com/search/label/Memcache" target="_blank">memcached </a>protocol to amplify the impact of such an attack. Memcached is typically used to speed up websites, but an issue with its UDP protocol makes the attack amplification possible, as noted by <a href="http://www.hackerschronicle.com/search/label/CloudFlare" target="_blank">CloudFlare</a>. 
 
Memcached, as is likely inferred by the name, is a tool that uses data caching to help ease the burden on data stores, it's not necessarily meant to be used with systems that are connected to the internet. But, that hasn't stopped attackers from finding a way to use it to launch and accelerate cyberattacks. By mislabeling a victim's IP as a target address, attackers can overload their network with traffic (up to 51,200x more in acceleration) and trigger a denial of service attack.

To fix its own problem, GitHub moved some of its traffic to Akamai for additional capacity at the edge. In its own post <a href="https://blogs.akamai.com/2018/03/memcached-fueled-13-tbps-attacks.html" target="_blank">Akamai</a>, one of the companies who discovered the vulnerability early on, wrote that it predicts "many more, potentially larger attacks in the near future. Akamai has seen a marked increase in scanning for open memcached servers since the initial disclosure." 
 
Josh Shaul, vice president of web security at Akami told, “we modeled our capacity based on five times the biggest attack that the internet has ever seen. So I would have been certain that we could handle 1.3 Tbps, but at the same time we never had a terabit and a half come in all at once.”

Security researchers at SiteLock have discovered that hundreds of websites based on WordPress, Joomla and CodeIgniter have been infected with <a href="http://www.hackerschronicle.com/search/label/Malwares" target="_blank">malware </a>that masquerades as legitimate ionCube-encoded files. 
 
ionCube is an encoding technology used to protect PHP software from being viewed, changed, and run on unlicensed computers. 
 
The experts were analyzing an infected <a href="http://www.hackerschronicle.com/search/label/Wordpress" target="_blank">WordPress </a>website when discovered a number of suspicious obfuscated files – such as “diff98.php” and “wrgcduzk.php” – appearing almost identical to legitimate ionCube-encoded files. Further analysis conducted revealed that hundreds of websites were infected by the same ionCube Malware. 
 
“While reviewing an infected site, the SiteLock Research team found a number of suspiciously named, obfuscated files that appear almost identical to legitimate ionCube-encoded files. We determined the suspicious ionCube files were malicious, and found that hundreds of sites and thousands of files were affected.” reads the analysis published by SiteLock. 
 
“Overall, our investigation found over 700 infected sites, totalling over 7,000 infected files.” 
 
Further analysis revealed that attackers also compromised <a href="http://www.hackerschronicle.com/search/label/Joomla" target="_blank">Joomla </a>and <a href="http://www.hackerschronicle.com/search/label/CodeIgniter" target="_blank">CodeIgniter </a>websites. Threat actors packed their malware in a manner that appears ionCube-encoded files. 
 
The malicious code could theoretically infect any website based on a web server running PHP, once decoded, the fake ionCube files compose the ionCube malware. 
 
“While there’s still some degree of obfuscation, the presence of the $_POST and $_COOKIE superglobals and the eval request at the end of the file reveal its true purpose: to accept and execute remotely supplied code.” continues the analysis. “It looks like the remote code supplied to this file is further obfuscated and there may be some sort of access control implemented, judging by the GUID-formatted string present.” 
 
 
The researchers also provided recommendations to mitigate the ionCube Malware, they suggest administrators check the presence of ionCube-encoded files as an indicator of compromise. 
 
If an infection is detected, the scanning of the entire site is recommended, to completely eliminate the threat, the researchers also suggest the adoption of a web application <a href="http://www.hackerschronicle.com/search/label/Firewall" target="_blank">firewall </a>(WAF). 
 
“If you find indicators of this infection, we strongly recommend having your site scanned for malware as soon as possible, as this malware seldom appears on its own.” concluded the analysis. 
 
“This is especially important if you are using an ionCube-encoded application, as manually differentiating the malicious files from the legitimate ones is difficult, and it is common to see up to 100 slightly different variants of this malware on a single site. “

A security researcher has found that one of the world’s largest <a href="http://www.hackerschronicle.com/search/label/VPN" target="_blank">Virtual Private Network (VPN)</a> providers is leaking users private information. Hotspot Shield, which has been downloaded over half a billion times and has been in operation for over a decade, has a bug which can reveal what country a user is located in, as well as leak the name of the WiFi network they are using. The <a href="http://www.hackerschronicle.com/search/label/Vulnerability" target="_blank">vulnerability </a>in Hotspot Shield’s VPN service was discovered by Paulos Yibelo. Yibelo reported his findings to Beyond Security’s SecuriTeam Secure Disclosure program. 
 
“By <a href="http://www.hackerschronicle.com/search/label/Information%20Disclosure" target="_blank">disclosing information</a> such as WiFi name, an attacker can easily narrow down or pinpoint where the victim is located,” Paulos Yibelo told. When an attacker knows what country a Hotspot Shield VPN user is from, they “can narrow down a list of places” their victim is from, Yibelo said. The vulnerability in Hotspot Shield’s VPN service was tested using a proof-of-concept code that Yibelo wrote. Using Yibelo’s code they were able to identify users WiFi networks, and the vulnerability kept working when tried from different computers and different network. 
 
Yibelo was able to write his proof-of-concept code very quickly, and it is only a few lines long. The code exploits a vulnerability in the local web server installed by Hotspot Shield. Private information and configuration data are returned when the exploit calls a JavaScript file being hosted on the web server. The private information of Hotspot Shield VPN users could be captured and stored from an infected website. According to Yibelo, he was able to successfully obtain Hotspot Shield VPN users IP addresses, though he was only having mixed results and was not always able to successfully capture real IP addresses. 
 
The developer of Hotspot Shield VPN, AnchorFree, Inc., is strongly denying that any user’s real IP addresses are being leaked through the vulnerability discovered by Paulos Yibelo. “We have reviewed and tested the researcher’s report. We have found that this vulnerability does not leak the user’s real IP address or any personal information, but may expose some generic information such as the user’s country. We are committed to the safety and security of our users, and will provide an update this week that will completely remove the component capable of leaking even generic information,” AnchorFree’s Tim Tsoriev said in a statement. 
 
After Yibelo discovered the vulnerability in Hotspot Shield VPN, he reported it to AnchorFree in December of last year but never received a response from the company. Yibelo then submitted the vulnerability to Beyond Security through their bug bounty program. Beyond Security also did not receive a response from AnchorFree. However, in February, AnchorFree finally addressed the issue with a new version of Hotspot Shield VPN which was recently released. The new version of Hotspot Shield VPN patches the vulnerability discovered by Yibelo. 
 
Last year Hotspot Shield VPN was accused by the Center for Democracy & Technology of selling their customers private information. A formal complaint was filed with the United States Federal Trade Commission (FTC) in which they allege that Hotspot Shield was guilty of employing unfair and deceptive trade practices. AnchorFree claimed that they did not collect any personal information about Hotspot Shield VPN users. Hotspot Shield VPN comes in both a free version, as well as a paid “Elite Version” subscription. The Center for Democracy & Technology discovered that Hotspot Shield VPN was sharing information after analyzing the VPN using Carnegie Mellon University’s Mobile App Privacy Compliance automated system on the free version of the Hotspot Shield VPN service.

Russian computer hackers operating in Colorado and 15 other states used data-mining <a href="http://www.hackerschronicle.com/search/label/Malwares" target="_blank">viruses </a>to steal thousands of <a href="http://www.hackerschronicle.com/search/label/Credit%20Card" target="_blank">credit card</a> numbers from U.S. residents in 20 states and sold them on the <a href="http://www.hackerschronicle.com/search/label/Darknet" target="_blank">darknet </a>for more than $3.6 million, according to federal court documents. 
 
As part of the wide-scale criminal operation, so-called “<a href="http://www.hackerschronicle.com/search/label/Carding" target="_blank">carders</a>” from Russia advertised and sold the numbers to Ukrainian operatives using the Rescator network of websites — named for a Ukranian hacker who specializes in the sale of stolen credit cards. 
 
<a href="http://www.hackerschronicle.com/search/label/Russian%20Hackers" target="_blank">Russian thieves</a> instructed clandestine organizations to pay for batches of stolen credit card numbers using <a href="http://www.hackerschronicle.com/2018/02/western-union-money-transfer-hacked.html" target="_blank">Western Union</a> and MoneyGram International, according to documents filed by federal prosecutors in Denver U.S. District Court. 
 
The documents did not indicate whether anyone has been arrested in connection to the scheme. Agents from the Department of Homeland Security based in Colorado uncovered the operation. The U.S. Attorney’s Office in Colorado filed forfeiture claims Friday against two Colorado bank accounts, the documents reveal. 
 
Criminals use software to access hidden websites and blogs on the <a href="http://www.hackerschronicle.com/search/label/Darknet" target="_blank">darknet </a>so they can operate <a href="http://www.hackerschronicle.com/search/label/Anonymous" target="_blank">anonymously</a>. As part of their investigation, Homeland Security agents made undercover purchases of batches of stolen credit cards. 
 
A web of conspirators in Colorado and 15 other states funneled money back to accounts set up in the Russian Federation. 
 
MoneyGram officials contacted Homeland Security agents in November of 2014 and notified them of 137 wire transfers totaling $170,000. The agents determined in March of 2016 that conspirators wired money to payees in the Ukraine, the documents indicate. In 2015 and 2016, conspirators allegedly sent 3,997 wires totaling $3,598,160, records indicate.</div>
