An anonymous reader writes: Imgur has been compromised by attackers looking for an opportunity to direct large volumes of traffic to 4chan. A Reddit thread explains that "when an Imgur image is loaded from /r/4chan [...] imgur loads a bunch of images from 8chan, which causes a DDoS to those sites." Meaning that if a user clicks an Imgur link on /r/4chan, it automatically makes around "500 requests" for one image from imageboard 4chan.org/8chan.

An anonymous reader writes: I have, for a while now, been collecting IP addresses from which email spam has been sent to, or attempted to be relayed through, my email server. I was wondering if I should publish them, so that others can adopt whatever steps are necessary to protect their email servers from that vermin. However, I am facing ethical issues here. What if the addresses are simply spoofed, and therefore branding them as spamming addresses might cause harm to innocent parties? What if, after having been co-opted by spammers, they are now used legitimately? I wonder if there's a market for all the thousands of webmail addresses that send Slashdot nothing but spam.

Lucas123 writes: Eighty-one percent of healthcare IT managers say their organizations have been compromised by at least one malware, botnet or other kind of cyber attack during the past two years, and only half of those managers feel that they are adequately prepared to prevent future attacks, according to a new survey by KPMG. The KPMG survey polled 223 CIOs, CTOs, chief security officers and chief compliance officers at healthcare providers and health plans, and found 65% indicated malware was most frequently reported line of attack during the past 12 to 24 months. Additionally, those surveyed indicated the areas with the greatest vulnerabilities within their organization include external attackers (65%), sharing data with third parties (48%), employee breaches (35%), wireless computing (35%) and inadequate firewalls (27%). Top among reasons healthcare facilities are facing increased risk, was the adoption of digital patient records and the automation of clinical systems.

Mickeycaskill writes: IBM says Tor is increasingly being used to scan organizations for flaws and launch DDoS, ransomware and other attacks. Tor, which provides anonymity by obscuring the real point of origin of Internet communications, was in part created by the US government, which helps fund its ongoing development, due to the fact that some of its operations rely on the network. However, the network is also widely used for criminal purposes. A report by the IBM says administrators should block access to Tor , noting a "steady increase" an attacks originating from Tor exit nodes, with attackers increasingly using Tor to disguise botnet traffic. "Spikes in Tor traffic can be directly tied to the activities of malicious botnets that either reside within the Tor network or use the Tor network as transport for their traffic," said IBM. "Allowing access between corporate networks and stealth networks can open the corporation to the risk of theft or compromise, and to legal liability in some cases and jurisdictions."

msm1267 writes: More than 2,000 websites running WordPress have been compromised and are responsible for a surge this week in traffic from the Neutrino Exploit Kit. Attacks against sites running older versions of the content management system, 4.2 and earlier, were spotted by Zscaler. Those sites are backdoored and redirect a victim's browser through iframes to a landing page hosting the exploit kit where a Flash exploit awaits. The exploits generally target Internet Explorer, Zscaler said, and victims' computers are eventually infected with CryptoWall 3.0 ransomware. This analysis is in line with a similar report from the SANS Institute, which pointed the finger at a particular cybercrime group that had steered away from using the prolific Angler Exploit Kit and moved operations to Neutrino.

Once a botnet has taken root in a large pool of computers, truly expunging it from them may be a forlorn hope. That, writes itwbennett, is: the finding of researchers in the Netherlands who analyzed the efforts of the Conficker Working Group to stop the botnet and find its creators. Seven years later, there are still about 1 million computers around the world infected with the Conficker malware despite the years-long cleanup effort. 'These people that remain infected — they might remain infected forever,' said Hadi Asghari, assistant professor at Delft University of Technology in the Netherlands. The research paper will be presented next week at the 24th USENIX Security Symposium in Washington, D.C. (And "Post-Mortem of a Zombie" is an exciting way to title a paper.)

Brian Krebs got his start as a reporter at The Washington Post and after having his entire network taken down by the Lion Worm, crime and cybersecurity became his focus. In 2005, Krebs started the Security Fix blog and Krebs On Security in 2009, which remains one of the most popular sources of cybercrime and security news. Brian is credited with being the first journalist to report on Stuxnet and one of his investigative series on the McColo botnet is estimated to have led to a 40-70% decline in junk e-mail sent worldwide. Unfortunately for Krebs, he's also well known to criminals. In 2013 he became one of the first journalists to be a victim of Swatting and a few months later a package of heroin was delivered to his home. Brian has agreed to give us some of his time and answer any questions you may have about crime and cybersecurity. As usual, ask as many as you'd like, but please, one per post.

An anonymous reader writes: New research indicates that Anonymous hacktivists (among other groups) took advantage of lazy security to hijack thousands of routers using remote access and default login credentials. "'For perpetrators, this is like shooting fish in a barrel, which makes each of the scans that much more effective,' the report explains. 'Using this botnet also enables perpetrators to execute distributed scans, improving their chances against commonplace blacklisting, rate-limiting and reputation-based defense mechanisms.'"

An anonymous reader writes: We've been in a malware arms race since the 1990s. Malicious hackers keep building new viruses, worms, and trojan horses, while security vendors keep building better detection and removal algorithms to stop them. Botnets are becoming more powerful, and phishing techniques are always improving — but so are the mitigation strategies. There's been some back and forth, but it seems like the arms race has been pretty balanced, so far. My question: will the balance continue, or is one side likely to take the upper hand over the next decade or two? Which side is going to win? Do you imagine an internet, 20 years from now, where we don't have to worry about what links we click or what attachments we open? Or is it the other way around, with threats so hard to block and DDoS attacks so rampant that the internet of the future is not as useful as it is now?

Trailrunner7 writes: The Obama administration has proposed an amendment to existing United Stated federal law that would give it a more powerful tool to go after botnets such as GameOver Zeus, Asprox and others. In recent years, Justice, along with private security firms and law enforcement agencies in Europe, have taken down various incarnations of a number of major botnets, including GameOver Zeus and Coreflood. These actions have had varying levels of success, with the GOZ takedown being perhaps the most effective, as it also had the effect of disrupting the infrastructure used by the CryptoLocker ransomware.

In order to obtain an injunction in these cases, the government would need to sue the defendants in civil court and show that its suit is likely to succeed on its merits. "The Administration's proposed amendment would add activities like the operation of a botnet to the list of offenses eligible for injunctive relief. Specifically, the amendment would permit the department to seek an injunction to prevent ongoing hacking violations in cases where 100 or more victim computers have been hacked. This numerical threshold focuses the injunctive authority on enjoining the creation, maintenance, operation, or use of a botnet, as well as other widespread attacks on computers using malicious software (such as "ransomware" )," assistant attorney general Leslie Caldwell wrote.

An anonymous reader writes The National Crime Agency's National Cyber Crime Unit worked with law enforcement colleagues in the Netherlands, Italy and Germany, co-ordinated through Europol's European Cybercrime Centre, to shut down command and control servers used by the RAMNIT botnet. Investigators believe that RAMNIT may have infected over three million computers worldwide, with around 33,000 of those being in the UK. It has so far largely been used to attempt to take money from bank accounts.

mpicpp sends word that the FBI and the U.S. State Department have announced the largest-ever reward for a computer hacking case. They're offering up to $3 million for information leading to the arrest of Evgeniy Bogachev, a 31-year-old Russian national. Bogachev is the alleged administrator of the GameOver Zeus botnet, estimated to have affected over a million computers, causing roughly $100 million in damages. "Bogachev has been charged by federal authorities in Pittsburgh, Pennsylvania, with conspiracy, computer hacking, wire fraud, bank fraud and money laundering... He also faces federal bank fraud conspiracy charges in Omaha, Nebraska related to his alleged involvement in an earlier variant of Zeus malware known as 'Jabber Zeus.'"

tsu doh nimh writes: The online attack service launched late last year by the same criminals who knocked Sony and Microsoft's gaming networks offline over the holidays is powered mostly by thousands of hacked home Internet routers, reports Brian Krebs. From the story: "The malicious code that converts vulnerable systems into stresser bots is a variation on a piece of rather crude malware first documented in November by Russian security firm Dr. Web, but the malware itself appears to date back to early 2014. As we can see in that writeup, in addition to turning the infected host into attack zombies, the malicious code uses the infected system to scan the Internet for additional devices that also allow access via factory default credentials, such as 'admin/admin,' or 'root/12345.' In this way, each infected host is constantly trying to spread the infection to new home routers and other devices accepting incoming connections (via telnet) with default credentials.

New submitter juniq writes: As one developer found out, posting your Amazon keys to GitHub on accident can be a costly mistake if they are not revoked immediately.

"When I woke up the next morning, I had four emails from Amazon AWS and a missed phone call from Amazon AWS. Something about 140 servers running on my AWS account. What? How? I only had S3 keys on my GitHub and they where gone within 5 minutes! Turns out through the S3 API you can actually spin up EC2 instances, and my key had been spotted by a bot that continually searches GitHub for API keys. Amazon AWS customer support informed me this happens a lot recently; hackers have created an algorithm that searches GitHub 24 hours per day for API keys. Once it finds one it spins up max instances of EC2 servers to farm itself bitcoins."

An anonymous reader writes: Distributed denial of service attacks have become a big problem. The internet protocol is designed to treat unlimited amounts of unsolicited traffic identically to important traffic from real users. While it's true DDoS attacks can be made harder by fixing traffic amplification exploits (including botnets), and smarter service front ends, there really doesn't seem to be any long term solution in the works. Does anyone know of any plans to actually try and fix the problem?

angry tapir writes An Android Trojan program that's behind one of the longest running multipurpose mobile botnets has been updated to become stealthier and more resilient. The botnet is mainly used for instant message spam and rogue ticket purchases, but it could be used to launch targeted attacks against corporate networks because the malware allows attackers to use the infected devices as proxies, according to security researchers.

An anonymous reader writes New malware targeting Mac machines, opening backdoors on them and roping them into a botnet currently numbering around 17,000 zombies has been spotted. The malware, dubbed Mac.BackDoor.iWorm, targets computers running OS X and makes extensive use of encryption in its routines, Dr. Web researchers noted. What's even more interesting is that it gets the IP address of a valid command and control (C&C) server from a post on popular news site Reddit. The malware is capable of discovering what other software is installed on the machine, opening a port on it, and sending a query to a web server to acquire the addresses of the C&C servers.

Bismillah writes The Bash "Shellshock" bug is being used to spread malware to create a botnet, that's active and attacking Akamai and Department of Defense networks. "The 'wopbot' botnet is active and scanning the internet for vulnerable systems, including at the United States Department of Defence, chief executive of Italian security consultancy Tiger Security, Emanuele Gentili, told iTnews. 'We have found a botnet that runs on Linux servers, named “wopbot", that uses the Bash Shellshock bug to auto-infect other servers,' Gentili said."

An anonymous reader writes Akamai Technologies is alerting enterprises to a high-risk threat of IptabLes and IptabLex infections on Linux systems. Malicious actors may use infected Linux systems to launch DDoS attacks against the entertainment industry and other verticals. The mass infestation of IptabLes and IptabLex seems to have been driven by a large number of Linux-based web servers being compromised, mainly by exploits of Apache Struts, Tomcat and Elasticsearch vulnerabilities. Attackers have used the Linux vulnerabilities on unmaintained servers to gain access, escalate privileges to allow remote control of the machine, and then drop malicious code into the system and run it. As a result, a system could then be controlled remotely as part of a DDoS botnet. The full advisory is available for download only with registration, but the (Akamai-owned) Prolexic page to do so is quite detailed.
