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.

Trailrunner7 writes The GameOver Zeus malware had a nice run for itself, making untold millions of dollars for its creators. But it was a run that ended with a multi-continent operation from law enforcement and security researchers to disassemble the infrastructure. Now researchers have identified a new variant of the Cridex malware that has adopted some of the techniques that made GOZ so successful in its day.

Researchers at IBM's X-Force research team have seen a new version of Cridex, which is also known as Bugat and Feodo, using some of the same techniques that GOZ used to such good effect. Specifically, the new strain of malware has adopted GOZ's penchant for using HTML injections, and the researchers say the technique is nearly identical to the way that GOZ handled it.

"There are two possible explanations for this. First, someone from the GOZ group could have moved to the Bugat team. This would not be the first time something like this has happened, which we've witnessed in other cases involving Zeus and Citadel; however, it is not very likely in this case since Bugat and GOZ are essentially competitors, while Zeus and Citadel are closely related. The second and more likely explanation is that the Bugat team could have analyzed and perhaps reversed the GOZ malware before copying the HTML injections that made GOZ so highly profitable for its operators," Etay Maor, a senior fraud prevention strategist at IBM, wrote in an analysis of the new malware.

New submitter Rigodi (1000552) writes "The New York Times reported on August 5th that a massive collection of stolen email passwords and website accounts have been accumulated by an alleged Russian "crime ring". Over 1.2 billion accounts were compromised ... the attack scheme is essentially the old and well known SQL injection tactic using a botnet. The Information has been made public to coincide with the Blackhat conference to cause a debate about the classic security account and password system weaknesses, urging the industry to find new ways to perform authentication. What do Black Hat security conference participants have to say about that in Vegas?

An anonymous reader writes "A team of researchers at the TU Berlin and RWTH Aachen presented an analysis of the Internet Census 2012 data set (here's the PDF) in the July edition of the ACM Sigcomm Computer Communication Review journal. After its release on March 17, 2013 by an anonymous author, the Internet Census data created an immediate media buzz, mainly due to its unethical data collection methodology that exploited default passwords to form the Carna botnet. The now published analysis suggests that the released data set is authentic and not faked, but also reveals a rather chaotic picture. The Census suffers from a number of methodological flaws and also lacks meta-data information, which renders the data unusable for many further analyses. As a result, the researchers have not been able to verify several claims that the anonymous author(s) made in the published Internet Census report. The researchers also point to similar but legal efforts measuring the Internet and remark that the illegally measured Internet Census 2012 is not only unethical but might have been overrated by the press."

An anonymous reader writes Bitdefender has discovered that a new variant of the Trojan component, Pushdo, has emerged. 77 machines have been infected in the UK via the botnet in the past 24 hours, with more than 11,000 infections reported worldwide in the same period. The countries most affected so far by the Pushdo variant are India, Vietnam and Turkey. Since Pushdo has resurfaced, the public and private keys used to protect the communication between the bots and the Command and Control Servers have been changed, but the communication protocol remains the same.

msm1267 (2804139) writes "The source code for Tinba, known as the smallest banker Trojan in circulation, has been posted on an underground forum. Researchers say that the files turned out to be the source code for version one of Tinba, which was identified in 2012, and is the original, privately sold version of the crimeware kit. Tinba performs many of the same malicious functions as other banker Trojans, injecting itself into running processes on an infected machine, including the browser and explorer.exe. The malware is designed to steal financial information, including banking credentials and credit-card data and also makes each infected computer part of a botnet. Compromised machines communicate with command-and-control servers over encrypted channels. Tinba got its name from an abbreviation of "tiny banker," and researchers say that it's only about 20 KB in size."

New submitter tylke (621801) writes: "Brian Krebs is reporting that the Gameover ZeuS botnet recently taken down by the U.S. Justice Department in June has re-emerged. The new variant of the Trojan is "stripped of the P2P code, and relies instead on an approach known as fast-flux hosting," a kind of round-robin technique that lets botnets hide phishing and malware delivery sites behind a network of compromised systems. Krebs says, "[T]his variant also includes a 'domain name generation algorithm' or DGA, which is a failsafe mechanism that can be invoked if the botnet’s normal communications system fails. The DGA creates a constantly-changing list of domain names each week (gibberish domains that are essentially long jumbles of letters). In the event that systems infected with the malware can’t reach the fast-flux servers for new updates, the code instructs the botted systems to seek out active domains from the list specified in the DGA. All the botmasters need to do in this case to regain control over his crime machine is register just one of those domains and place the update instructions there." (Disclosure: I work for Malcovery Security, the company credited with identifying the new variant.)

chicksdaddy writes: When it comes to fighting cybercrime, few companies can claim to have done as much as Redmond, Washington-based Microsoft, which spent the last five years as the Internet's Dirty Harry: using its size, legal muscle and wealth to single-handedly take down cyber criminal networks from Citadel, to Zeus to the recent seizure of servers belonging to the (shady) managed DNS provider NO-IP. The company's aggressive posture towards cyber crime outfits and the companies that enable them has earned it praise, but also criticism. That was the case last week after legitimate customers of NO-IP alleged that Microsoft's unilateral action had disrupted their business. There's evidence that those criticisms are hitting home – and that Microsoft may be growing weary of its role as judge, jury and executioner of online scams. Microsoft Senior Program Manager Holly Stewart gave a sober assessment of the software industry's fight against cyber criminal groups and other malicious actors. Speaking to a gathering of cyber security experts and investigators at the 26th annual FIRST Conference in Boston, she said that the company has doubts about the long term effectiveness of its botnet and malware takedowns.

tsu doh nimh (609154) writes "The U.S. Justice Department announced today an international law enforcement operation to seize control over the Gameover ZeuS botnet, a sprawling network of hacked Microsoft Windows computers that currently infects an estimated 500,000 to 1 million compromised systems globally. Experts say PCs infected with Gameover are being harvested for sensitive financial and personal data, and that the botnet is responsible for more than $100 million in losses from online banking account takeovers. The government alleges that Gameover also was rented out to an elite cadre of hackers for use in online extortion attacks, spam and other illicit moneymaking schemes. In a complaint unsealed today, the DOJ further alleges that ZeuS and Gameover are the brainchild of a Russian man named Evgeniy Mikhailovich Bogachev, a.k.a. 'Slavik.'"

An anonymous reader writes "Brian Krebs has a followup to this week's 400 Gbps DDoS attack using NTP amplification. Krebs, as a computer security writer, has often been the target of DDoS attacks. He was also hit by a 200Gbps attack this week (apparently, from a 15-year-old in Illinois). That kind of volume would have been record-breaking only a couple of years ago, but now it's just normal. Arbor Networks says we've entered the 'hockey stick' era of DDoS attacks, as a graph of attack volume spikes sharply over the past year. CloudFlare's CEO wrote, 'Monday's DDoS proved these attacks aren't just theoretical. To generate approximately 400Gbps of traffic, the attacker used 4,529 NTP servers running on 1,298 different networks. On average, each of these servers sent 87Mbps of traffic to the intended victim on CloudFlare's network. Remarkably, it is possible that the attacker used only a single server running on a network that allowed source IP address spoofing to initiate the requests. An attacker with a 1 Gbps connection can theoretically generate more than 200Gbps of DDoS traffic.' In a statement to Krebs, he added, 'We have an attack of over 100 Gbps almost every hour of every day.'"
