An anonymous reader writes: A trojan that targeted Drupal sites on Linux servers last May that was incredibly simplistic and laughable in its attempt to install (and fail) web ransomware on compromised websites, has now received a major update and has become a top threat on the malware scene. That trojan, named Rex, has evolved in only three months into an all-around threat that can: (1) compromise servers and devices running platforms like Drupal, WordPress, Magento, Jetspeed, Exarid, AirOS; (2) install cryptocurrency mining in the background; (3) send spam; (4) use a complex P2P structure to manage its botnet; and (5) install a DDoS agent which crooks use to launch DDoS attacks.

Worse is that they use their DDoS capabilities to extort companies. The crooks send emails to server owners announcing them of 15-minute DDoS tests, as a forewarning of future attacks unless they pay a ransom. To scare victims, they pose as a known hacking group named Armada Collective. Other groups have used the same tactic, posing as Armada Collective, and extorting companies, according to CloudFlare.

An anonymous reader writes from a report via Softpedia: There is an insecure IoT smart electrical socket on the market that leaks your Wi-Fi password, your email credentials (if configured), and is also poorly coded, allowing attackers to hijack the device via a simple command injection in the password field. Researchers say that because of the nature of the flaws, attackers can overwrite its firmware and add the device to a botnet, possibly using it for DDoS attacks, among other things. Bitdefender didn't reveal the device's manufacturer but said the vendor is working on a fix, which will be released in late Q3 2016. Problems with the device include a lack of encryption for device communications and the lack of any basic input sanitization for the password field. "Up until now most IoT vulnerabilities could be exploited only in the proximity of the smart home they were serving, however, this flaw allows hackers to control devices over the internet and bypass the limitations of the network address translation," says Alexandru Balan, Chief Security Researcher at Bitdefender. "This is a serious vulnerability, we could see botnets made up of these power outlets."

Mark Wilson, writing for BetaNews: Professional social network LinkedIn is suing 100 anonymous individuals for data scraping. It is hoped that a court order will be able to reveal the identities of those responsible for using bots to harvest user data from the site. The Microsoft-owned service takes pride in the relationship it has with its users and the security it offers their data. Its lawsuit seeks to use the data scrapers' IP addresses and then discover their true identity in order to take action against them. LinkedIn says that a botnet has been used to gain access to user data which is then passed on to third parties. The site has a number of measures in place to prevent this type of data harvesting, but it seems that scrapers have found a way to circumvent these security restrictions. A series of automated tools -- FUSE, Quicksand, Sentinel, and Org Block -- are used to monitor suspicious activity and blocking scraping.

An anonymous reader quotes a report from SiliconBeat: Data thieves used a massive "botnet" against professional networking site LinkedIn and stole member's personal information, a new lawsuit reveals. "LinkedIn members populate their profiles with a wide range of information concerning their professional lives, including summaries (narratives about themselves), job histories, skills, interests, educational background, professional awards, photographs and other information," said the company's complaint, filed in Northern California U.S. District Court (PDF). "During periods of time since December 2015, and to this day, unknown persons and/or entities employing various automated software programs (often referred to as 'bots') have extracted and copied data from many LinkedIn pages." It is unclear to what extent LinkedIn has been able to stymie the attack. A statement from the firm's legal team suggests one avenue of penetration has been permanently closed, but does not address other means of incursion listed in the lawsuit. "Their actions have violated the trust that LinkedIn members place in the company to protect their information," the complaint said. "LinkedIn will suffer ongoing and irreparable harm to its consumer goodwill and trust, which LinkedIn has worked hard for years to earn and maintain, if the conduct continues." LinkedIn says it has more than 128 million U.S. members and more than 400 million worldwide. According to the complaint, the hackers got around six LinkedIn cybersecurity systems, and also manipulated a cloud-services company that was on the company's "whitelist" of "popular and reputable service providers, search engines and other platforms" which interact with LinkedIn under less severe security measures than other third parties. The manipulation allowed the hackers to send requests to LinkedIn servers. "This was not an attack or data breach where confidential data was stolen," LinkedIn's legal team said in a statement. "This suit is about unknown entities using automated systems to scrape and copy data that members have made available on LinkedIn, violating the law and our Terms of Service."

An anonymous reader writes from a report via Softpedia: "The hacking crew [PoodleCorp] that promised to launch DDoS attacks on the Pokemon GO servers on August 1 suffered a major setback, after someone hacked their site, dumped the database, and shared it with data breach index service LeakedSource," reports Softpedia. "PoodleCorp responded to LeakedSource's announcement with what they knew best, a DDoS attack." When that happened, LeakedSource started looking at the leaked data and discovered full names for three of PoodleCorp's members, saying they intend to share it with authorities. Soon after, PoodleCorp stopped the DDoS against LeakedSource and went to annoy Blizzard gamers. "It's a terrible idea to attack a business that knows something about virtually everybody," a LeakedSource spokesperson said.

An anonymous reader writes from a report via Schneier on Security: Two researchers have discovered over 100 Tor nodes that are spying on hidden services. Cory Doctorow from Boing Boing reports: "These nodes -- ordinary nodes, not exit nodes -- sorted through all the traffic that passed through them, looking for anything bound for a hidden service, which allowed them to discover hidden services that had not been advertised. These nodes then attacked the hidden services by making connections to them and trying common exploits against the server-software running on them, seeking to compromise and take them over. The researchers used 'honeypot' .onion servers to find the spying computers: these honeypots were .onion sites that the researchers set up in their own lab and then connected to repeatedly over the Tor network, thus seeding many Tor nodes with the information of the honions' existence. They didn't advertise the honions' existence in any other way and there was nothing of interest at these sites, and so when the sites logged new connections, the researchers could infer that they were being contacted by a system that had spied on one of their Tor network circuits. No one knows who is running the spying nodes: they could be run by criminals, governments, private suppliers of 'infowar' weapons to governments, independent researchers, or other scholars (though scholarly research would not normally include attempts to hack the servers once they were discovered)." The Tor project is aware of the attack and is working to redesign its system to try and block it. Security firm Bitdefender has issued an alert about a malicious app called EasyDoc that hands over control of Macs to criminals via Tor.

An anonymous reader writes: Security firm Bitdefender has issued an alert about a malicious app that hands over control of Macs to criminals via Tor. The software, called EasyDoc Converter.app, is supposed to be a file converter but doesn't do its advertised functions. Instead it drops complex malware onto the system that subverts the security of the system, allowing it to be used as part of a botnet or to spy on the owner. "This type of malware is particularly dangerous as it's hard to detect and offers the attacker full control of the compromised system," said Tiberius Axinte, Technical Leader, Bitdefender Antimalware Lab. "For instance, someone can lock you out of your laptop, threaten to blackmail you to restore your private files or transform your laptop into a botnet to attack other devices. The possibilities are endless." The malware, dubbed Backdoor.MAC.Eleanor, sets up a hidden Tor service and PHP-capable web server on the infected computer, generating a .onion domain that the attacker can use to connect to the Mac and control it. Once installed, the malware grants full access to the file system and can run scripts given to it by its masters.A report on AppleInsider says that malware can also control the FaceTime camera on a victim's computer. But thankfully, Apple's Gatekeeper security prevents the unsigned app from being installed.

An anonymous reader writes: "A botnet of over 25,000 bots is at the heart of recent DDoS attacks that are ferociously attacking businesses across the world with massive Layer 7 DDoS attacks that are overwhelming Web servers, occupying their resources and eventually crashing websites," reports Softpedia. This botnet's particularity is the fact that attacks never fluctuated and the attackers managed to keep a steady rhythm. This is not a classic botnet of infected computers that go on and off, but of compromised CCTV systems that are always on and available for attacks. The brands of CCTV DVRs involved in these attacks are the same highlighted in a report by a security researcher this winter, who discovered a backdoor in the firmware of 70 different CCTV DVR vendors. These companies had bought unbranded DVRs from Chinese firm TVT. When informed of the firmware issues, TVT ignored the researcher and the issues were never fixed, leading to crooks creating this huge botnet.

An anonymous reader writes: Somebody created a botnet of three million Twitter accounts in one single day, and Twitter staff didn't even flinch -- even if the huge 35.4 registrations/second should have caught the eye of any IT staffer. Another weird particularity is that the botnet was also synchronized to use Twitter usernames similar to Twitter IDs. Couple this with a gap of 168 million IDs before and after the botnet's creation, it appears that someone specifically reserved those IDs. The IDs were reserved in October 2013, but the botnet was registered in April 2014 (except 2 accounts registered in March 2014). It's like Twitter's registration process skipped 168 million IDs, and someone came back a few months later and used them. [Softpedia reports:] "The botnet can be found at @sfa_200xxxxxxx, where xxxxxxx is a number that increments from 0 000 000 to 2 999 999. All accounts have a similar structure. They have "name" instead of the Twitter profile handle, display the same registration date, and feature the text "some kinda description" in the profile bio field. Additionally, there are also two smaller botnets available as well. One can be found between @cas_2050000000 and @cas_2050099999. Sadbottrue says it was registered between March 3 and March 5, 2015. The second is between @wt_2050100000 and @wt_2050199999, and was registered between October 23 and November 22, 2014." Both have 100,000 accounts each. Theoretically, these types of botnets can be used for malware C and C servers, Twitter spam, or to sell fake Twitter followers. At 3 million bots, the botnet accounts for 1% of Twitter's monthly active users.

dkatana writes: The University of Calgary paid C$20,000 ransom this week after an attack on May 28 targeted computers used by staff and faculty members, crippling multiple systems and encrypting data files and email accounts. After determining that they were unable to recover the data the ransom was paid to "protect the quality and nature of the information we generate at the university," said an official in a press release.

The fact that higher education institutions are now being targeted by ransomware is raising serious questions about their ability to protect their data and critical information systems.
IT World Canada has more details, noting that the university has reported the incident to the police, and that Trend Micro "has seen a 20% uptick in malicious requests to command and control infrastructure from infected machines over the last three months" -- several thousand requests a day.

An anonymous reader writes: The Computer Fraud and Abuse Act is "vague, draconian, and notoriously out of touch with how we use computers today," warns the EFF. But instead of reforming it, two U.S. Senators "are on a mission to make things worse..." The senators' proposed Botnet Prevention Act of 2016 "could make criminals of paid researchers who test access in order to identify, disclose, and fix vulnerabilities," according to the EFF. And the bill would also make it a felony to damage "critical infrastructure," which may include software companies and ISPs (since they're apparently using the Department of Homeland Security's definition).

The harsher penalties would ultimately give prosecutors much more leverage for plea deals. But worst of all, the proposed bill even "empowers government officials to obtain court orders to force companies to hack computer users for a wide range of activity completely unrelated to botnets. What's worse is that the bill allows the government to do this without any requirement of notice to non-suspect or innocent customers or companies, including botnet victims... These changes would only increase -- not alleviate -- the CFAA's harshness, overbreadth, and confusion."
The CFAA was originally written in 1986, and was partly inspired by the 1983 movie "WarGames".

A group of bipartisan senators introduced a bill on Thursday that blocks a pending judicial rule change allowing U.S judges to issue search warrants for remote access to computers in any jurisdiction, even overseas. Associated Press reports: Justice Department officials say that requirement is not practical in complex computer crime cases where investigators don't know the physical location of the device they want to search. In instances when cybercriminals operate on networks that conceal their identity and location, the government wants to ensure that any magistrate in a judicial district where a crime may have occurred can sign off on a search warrant that gives investigators remote access to the computer. The Obama administration says that authority is especially critical in cases involving botnets, which are networks of computers infected with a virus that spill across those districts. As it now stands, federal officials say, they might have to apply for nearly identical warrants in 94 different courthouses to disrupt a botnet.The U.S. Justice Department has pushed for the rule change since 2013. It has assumed it as a "procedural tweak" needed to modernize the criminal code to pursue sophisticated 21st century criminals, reports Reuters. Congress has until Dec 1 to vote to reject, amend or postpone the changes to Rule 41 of the federal rules of criminal procedure. If lawmakers fail to act, the change will automatically take effect, a scenario seen as likely given the short timeline. ZDNet has more details.

Botnet herders have sophisticated "disaster recovery" plans, according to speakers at a recent cybersecurity conference, with many splitting their botnets into smaller herds, making them more resilient. In addition, kierny writes: Researchers say these backup botnets are tough to detect, until gangs have already spooled them up and put them to use in major campaigns... "What we're seeing is the bad guys are starting to learn from this," said Steven Wilson, head of the European Cybercrime Center at Europol -- the EU's law enforcement agency...
Wilson said authorities are now gathering tremendous amounts of data by "sink-holing" -- forcibly redirecting the infected endpoints onto servers controlled by law enforcement. And he also reports that authorities have also successfully mined the blockchains of bitcoin transactions for information. Eamonn Keane, A detective from a cybercrime unit with the Scotland Police, added that authorities are also infiltrating dark net forums to bust bitcoin-using criminals. "Are law enforcement in there? Absolutely... We have a mandate to protect you in the real world; increasingly it's moving into the online environment."

schwit1 quotes a report from ZDNet: A botnet and cyberattack campaign is infecting victims across the globe and appears to be tracking the actions of specially selected targets in sectors ranging from government to engineering. Researchers from Forcepoint Security Labs have warned that the campaign it has dubbed 'Jaku' -- after a planet in the Star Wars universe because of references to the sci-fi saga in the malware code -- is different to and more sophisticated than many botnet campaigns. Rather than indiscriminately infecting victims, this campaign is capable of performing "a separate, highly targeted operation" used to monitor members of international non-governmental organizations, engineering companies, academics, scientists and government employees, the researchers said. The findings are set out in Forcepoint's report on Jaku, which outlines how of the estimated 19,000 unique victims, 42 percent are in South Korea and a further 31 percent in Japan. Both are countries and neighbors of North Korea. A further nine percent of Jaku victims are in China, six percent in the US, with the remainder spread across 130 other countries.

Patrick O'Neill quotes a report from The Daily Dot: The FBI team that brought down Silk Road has a new home. After headline-grabbing investigations, arrests, and prosecutions on some of America's highest-profile cybercriminals, five of U.S. law enforcement's most prized cybercrime aces have all left government service for greener pastures -- a titan consulting firm called Berkeley Research Group (BRG). BRG's newly hired gang of five includes former federal prosecutor Thomas Brown, as well as former FBI agents Christopher Tarbell, Thomas Kiernan, and Ilhwan Yum -- names that punctuated many of the biggest cybercrime stories of the last decade including Silk Road, LulzSec, Liberty Reserve, as well as the hacks of Citibank, PNC Bank, and the Rove Digital botnet; and the prosecution of Samarth Agrawal for stealing crucial code for high-frequency trading from the multinational, multibillion dollar bank Societe Generale. "Private industry provides a lot of opportunity," NYPD intelligence chief Thomas Galati told Congress earlier this year. "So I think the best people out there are working for private companies, and not for the government."

An anonymous reader writes: According to Softpedia, "Security researchers from SurfWatch Labs have shut down a secret plan to hack and infect hundreds or possibly thousands of forums and websites hosted on the infrastructure of Invision Power Services, makers of the IP.Board forum platform." The man behind this plan was a hacker known as AlphaLeon, maker of the Thanatos malware-as-a-service platform. AlphaLeon hacked IP.Board's customer hosting platform, and was planning to place an exploit kit that would infect the visitors to these websites with his Thanatos trojan, in order to grow his botnet. Some of the companies using IP.Board-hosted forums include Evernote, the NHL, the Warner Music Group, and Bethesda Softworks (Elder Scrolls, Fallout, Wolfenstein, Doom games).

Warwick Ashford, reporting for ComputerWeekly: Qbot malware will become a potent threat, facilitated by exploit kits for initial infection and automated to gain maximum victim count, warns BAE Systems. The incident response team at BAE Systems is warning of a strain of the virulent Qbot malware that has hit thousands of public sector computers around the world. The malware -- also known as the Qakbot botnet -- first appeared in 2009 and was uploading 2GB of stolen confidential information to its FTP servers each week by April 2010 from private and public sector computers, including 1,100 on the NHS network in the UK. A modified version of the malware has resurfaced that is believed to have infected more than 54,000 PCs in thousands of organisations around the world and added them to its botnet of compromised machines, with 85% of infections in the US.

An anonymous reader shares an article on Ars Technica: A botnet that enslaved about 4,000 Linux computers and caused them to blast the Internet with spam for more than a year has finally been shut down. Sophisticated Mumblehard spamming malware flew under the radar for five years. Known as Mumblehard, the botnet was the product of highly skilled developers. It used a custom "packer" to conceal the Perl-based source code that made it run, a backdoor that gave attackers persistent access, and a mail daemon that was able to send large volumes of spam. Command servers that coordinated the compromised machines' operations could also send messages to Spamhaus requesting the delisting of any Mumblehard-based IP addresses that sneaked into the real-time composite blocking list, or CBL, maintained by the anti-spam service. "There was a script automatically monitoring the CBL for the IP addresses of all the spam-bots," researchers from security firm Eset wrote in a blog post published Thursday. "If one was found to be blacklisted, this script requested the delisting of the IP address. Such requests are protected with a CAPTCHA to avoid automation, but OCR (or an external service if OCR didn't work) was used to break the protection."

The Project Shield initiative allows websites to redirect traffic through Google's existing infrastructure, in order to keep their content online in the face of such attacks. Google will aim to work with smaller sites which do not necessarily have the money or are not fully equipped with strong enough infrastructure to the attacks. However, the Shield tool has also been made available to larger outlets, such as popular news sites and human rights platforms.

An anonymous reader writes: The Linux Mint website was hacked last night and was pointing to malicious ISOs that contained an IRC bot known as TSUNAMI, used as part of an IRC DDoSing botnet. While the Linux Mint team says they were hacked via their WordPress site, security experts have discovered that their phpBB forum database was put up for sale on the Dark Web at around the same time of the hack. Also, it seems that after the Linux Mint team cleaned their website, the hackers reinfected it, which caused the developers to take it down altogether.
