China Overtakes US as Top Source of Distributed Denial of Service Attacks

More Distributed Denial of Service (DDoS) attacks originated in China than in any other country, followed by Germany and the United States, according to the Q1 2015 State of the Internet – Security Report by cloud services provider Akamai. China is responsible for 23.45% of the world’s DDoS attacks , malicious attempts to make servers unavailable to users by interrupting the services of a host connected to the Internet, while 17.39% came from Germany and 12.18% from the US. The number of Chinese DDoS has risen 66% in attack source IPs compared with the US, although researchers say it could be attributed to the increase in redirected traffic from Asia. The United States was the origin of 32% of DDoS attacks in Q4 2014, with China at 18%. The percentage drop does not indicate a decline in attacks from these countries, but rather a change in proportions as the number of total DDoS attacks worldwide soars. DDoS attacks have increased 117% quarter-over-quarter and 35% quarter-on-quarter. The quarter set a record for the number of DDoS attacks observed over the Prolexic network, while the attack duration is now 43% longer than in Q1 2014, according to the report. The US was the top source country of attacking IPs, at 52%, followed by China at 11% and Brazil at 6%, among source countries for web application attacks. US-based websites were the most targeted for web application attacks in Q1 2015, receiving 82% of attacks , while no other country was targeted for more than 2% of attacks. Retail, media/entertainment and hotel/travel were the most targeted industries for web application attacks in Q1 2015. This stems from previous attacks on the financial service sector, which hardened its security policy significantly. Meanwhile, retail and media attacks and breaches of 2014 signaled that these industries were softer targets, leading attackers to probe them for vulnerabilities.

Google Chrome extension turned users into a DDoS botnet

Hola turned users’ PCs into a botnet, without their consent. Hola, an online service used for watching blocked videos and TV shows from websites outside of your country, has turned users’ PCs into a botnet without their consent. According to The Verge ,   the free-to-use software – which is available as a Chrome plugin – was secretly selling users’ “idle resources” (bandwidth), allowing anyone to buy traffic and redirect it to any site as a denial-of-service attack. This means that Hola users could have been part of a botnet attack. The reports came to light after sites were affected by the denial-of-service attacks from Hola’s network. Hola’s founder Ofer Vilenski said the site has “always made it clear” how its business model works. However, according to The Verge Hola’s users seem to have been almost universally unaware that their bandwidth was being sold off.

How Visual Basic Broke Modern Python: Welcome to the World of High Orbit Ion Cannon

In 2012, Anonymous introduced HOIC (high orbit ion cannon) as a replacement to LOIC (low orbit ion cannon). Unlike its predecessors, that were built upon C#, and later java. This new DDoS player was built upon the unsuspecting language of Visual Basic. Taught in high school classrooms, Visual Basic was largely seen by the programming community as a means for kids and young programmers to get their feet wet in the experience of programming. Considered by many programmers as grossly inefficient and a memory hog; Visual Basic was an unsuspected carrier for what would become one of the most powerful means of DDoS. One of the popular notions of HOIC has been its ability to randomize variables such as: user agent, referrer and URI, during an attack. In the same manner, an attack tool known as HULK (developed by: Barry Shteiman, 2012), written in Python, was developed in recent history. Within a controlled environment we tested these DDoS tools to judge their effectiveness and total output. In controlled trials the DDoS output of LOIC (Visual Basic on Windows) outperforms the DDoS output HULK (Python on Linux) by +40%. Figure 1: HOIC Test in Stable Windows Environment Figure 2: HULK Test While many of us in the Internet security industry ridicule and downplay the “kiddie hacker;” it is clear that it sometimes only takes a kiddie to build an empire. Lessons in open source economics teach us that in an open access environment, it takes only a small few to bring about radical change and innovation. Today HOIC has become one of the primary tools of groups such as anonymous. From this lesson, we can expect that challenges and sudden changes, will not come from those paid hundreds of thousands a year; but from those small few kiddies, whom are politically motivated and are paid nothing.

DDoS Attack Update: Idaho Teen Faces Felony Charges After Unleashing a DDoS Attack on School District

In May 15, KTVB reported that a student recently launched a cyber-attack on one of Idaho’s largest school districts. The attack, which was identified as a Distributed Denial of Service (DDoS), practically rendered the entire district’s internet unable to function. The attack was so powerful that it caused internet problems for the affected school district for weeks without ceasing. A lot of Idaho students working on achievement tests lost all their data, and some even had to retake the exam multiple times because of the gravity of the attack. Even the administrative network itself, which, unfortunately, included the teachers’ payroll data was compromised. A DDoS attack occurs when multiple systems compromised by a Trojan are used by a host, or in this case, a channel, to target a single host simultaneously causing a denial of service. In simple terms, the attack floods a single network with immeasurable internet traffic until it simply stops dead on its tracks. Most of these attacks exploit problems within the victim computer’s TCP/IP system. Because a DDoS attack comes from hundreds, possibly even thousands of sources at once, it is practically impossible for any program on earth to track down the actual source of the problem. To make matters worse, a DDoS attack makes it impossible to identify actual, legitimate traffic, because everything gets lost in a haze of incoming data. Despite the overwhelming odds, the authorities managed to trace the attacker’s IP address back to the high school student. Today, he faces the possibility of expulsion, as well as 180 days in a juvenile detention center. Authorities say that he might even be facing serious federal charges. Moreover, the culprit’s parents will also be expected to pay any losses that the school district has incurred due to the attacks. A representative for the West Ada School District said that there might be other students within the area who know how to carry out this cyber-attack. Nevertheless, the spokesperson reassured everyone that further attacks will be dealt with more readily. The district also sent a message to parents of students enrolled in their schools, urging them to help keep their children from committing cyber attacks.

South Africa a target for DDoS

South Africa is the most targeted country in Africa when it comes to distributed denial-of-service (DDOS) attacks. This was revealed by Vernon Fryer, chief technology security officer at Vodacom, in a keynote address during ITWeb Security Summit 2015, in Midrand, this morning. In computing, a DDOS attack is an attempt to make a machine or network resource unavailable to its intended users. Such an attack generally consists of efforts to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet. Fryer was speaking with reference to statistics from the Vodacom Cyber Intelligence Centre, which the company established eight years ago to analyse the threat landscape on the African continent. He revealed over the past 18 months, there has been a marked increase in DDOS attacks on the continent, with a typical attack averaging 9Gbps. “There has been about a 150% increase in the number of DDOS [attacks] in the last 18 months in Africa,” he said. In terms of the number of attacks, Kenya, Uganda, Algeria, Nigeria and Tanzania respectively come after SA, said Fryer, pointing to the analysis done by the Vodacom Cyber Intelligence Centre last Thursday. According to Fryer, the majority of in-bound traffic to SA emanated mainly from China, Germany, Brazil, Vietnam, Russia, Cyprus, Turkey, Switzerland, Canada and the US. However, he noted, it was surprising Switzerland and Canada were featuring on the list this year, something never witnessed previously. Another unexpected trend showed traffic coming from Swaziland, he added, pointing out the growing number of Chinese communities in the country could be a reason for this spike. Describing some of the attack vectors cyber criminals were making use of in the region, Fryer pointed to scareware, ransomware, fake anti-virus, as well as TDSS Rootkit, among others. The trending malware included KINS Trojan, Skypot, VirRansom, SpyEye Trojan and the Chameleon Botnet. With regard to ransomware attacks in Africa, Tanzania is the most attacked on the African continent, Fryer said. He also noted the trending hacker groups in Africa include Anonymous, also known as the Lizard Squad, the Syrian Electronic Army, as well as the Yemen Cyber Army. Faced with the rise in the level and sophistication of attacks, Fryer said organisations need to constantly monitor the behaviour of their firewalls. Typically, he said, organisations take about five years without monitoring their firewall. “We need to understand if our firewalls are capable of handling today’s threats. Thus, the performance of firewalls needs to be constantly monitored,” he concluded. Source: http://www.itweb.co.za/index.php?option=com_content&view=article&id=143446:SA-a-target-for-DDOS&catid=234

Teen hires attacker to DDoS his school district

A high school boy might have to face state and federal charges for allegedly hiring a third party and launching a DDoS attack against the West Ada school district, Idaho, US. A 17-year old high school student (the name cannot be disclosed because of him being a minor) might be accused of launching a distributed denial of service (DDoS) attack after hiring a third party. The attack crippled operations at more than 50 schools of the district for a week previously this month. DDoS is a type of attack in which the servers of a particular online service are slowed to such an extent that their processing ability gets clogged up. According to KTVB report , the West Ada students suffered assorted misery due to the attack such as they lost their data on the Idaho Standard Achievement tests. Some of the students also had taken the tests multiple times. The attack lasted around a week and during this phase the online classes and textbooks could not be accessed. Moreover, the faculty and staff also experienced problems in accessing business and administrative systems such as payroll. The IP address from where the attack was launched was finally traced by the school district’s IT staff, which led them to the high schooler. The boy has been suspended from Eagle High but school administration suggested that he should be expelled. According to the Sheriff’s Office, the seventeen year old will most likely be charged with computer crime felony, which can send him to a juvenile detention facility for up to 180 days as the teenager paid someone to overwhelm the system with traffic from multiple sources. Additionally, the boy’s family will also be held responsible for a financial restitution for covering the losses since operations at around 50 schools got disrupted due to the attack. This is not the first time when a teenager attacked an educational institution. In April 12, 2015, Domanik Green, a 14-year-old student studying at Florida’s Paul R. Smith Middle School managed to bypass the school’s computer security network using just his computer skills and gained access to the server that contained FCAT (Florida Comprehensive Assessment Test) data.

High schooler allegedly hired third party to DDoS his school district

A 17-year-old high school boy may face state and federal charges for allegedly having paid a third party to launch a distributed denial of service (DDoS) attack that crippled the West Ada school district in Idaho, US, for a week and a half earlier this month. Because he’s a minor, he can’t be named. A DDoS is an attack wherein the servers of a targeted online service are slowed to a crawl with loads of pointless data like email or file uploads that clog up their processing ability. KTVB reports that West Ada students suffered assorted misery because of the attack, including losing their work on the Idaho Standard Achievement tests. Some students had to take the tests multiple times. Meanwhile, online classes and textbooks weren’t available for much of the week, and faculty and staff had problems accessing administrative and business systems, including payroll. The school district’s IT staff eventually traced an IP address back to the 17-year-old, who was suspended from Eagle High. School officials are recommending that he be expelled. The sheriff’s office told the TV station that the boy will likely be charged with a felony charge of computer crime, which is punishable by up to 180 days in a juvenile detention facility. In addition, his family will be responsible for financial restitution to cover costs incurred by the school district. Operations at more than 50 schools were disrupted because of the attack. As of Wednesday, investigators were also looking into whether a younger student – one attending Eagle Middle School – attempted a similar attack this week. School officials sent parents a letter on Friday that urged them to talk with their children about the consequences of committing cyber attacks such as this one. We can assure students and parents that the consequences associated with a DDoS attack are far from trivial. Examples include two online gaming programmers from Poland who were given 5-year jail sentences in December 2013 for DDoS and cyber-extortion of a UK online marketing company and a US internet software company. In that same month, a US man was fined $183,000 (£116,772) after joining, for merely 1 minute, an Anonymous DDoS of the enormous, multinational corporation Koch Industries. When it comes to DDoS, the law doesn’t spare you if you’re a kid. In fact, a 16-year-old London schoolboy was arrested under suspicion of involvement in the 2013 DDoS attack against Spamhaus: an attack of unprecedented ferocity. He pleaded guilty in 2014. Then too, a UK teenager was arrested in January for possibly having a hand in the PlayStation/Xbox Live DDoS that Grinched up gamers’ Christmas day playing. We often hear DDoS’ers trying to justify DDoSes under the premise that really, companies should be thanking the attackers for “raising awareness” of their vulnerability. That’s an old, tired spiel that we got from Lizard Squad members after they ruined Christmas with their XBox Live/PlayStation attack. Or, in the words of a man who claimed to speak for the attackers, they did it … …to raise awareness, to amuse ourselves… But as Naked Security’s Mark Stockley said at the time, a DDoS attack isn’t a skilful hack. You don’t need elite lock-picking skills to pull it off, because you’re not picking a lock. Rather, you’re blocking the door from the outside with as much garbage as you can pile up. Is DDoSing a company, or your school, or any online service, worth the lulz? For an answer, we can ask the LulzSec guys—If they’re out of prison, maybe they can let us know.
