A 100,000-Router Botnet Is Feeding On a 5-Year-Old UPnP Bug In Broadcom Chips (arstechnica.com)
An anonymous reader quotes a report from Ars Technica: A recently discovered botnet has taken control of an eye-popping 100,000 home and small-office routers made from a range of manufacturers, mainly by exploiting a critical vulnerability that has remained unaddressed on infected devices more than five years after it came to light. Researchers from Netlab 360, who reported the mass infection late last week, have dubbed the botnet BCMUPnP_Hunter. The name is a reference to a buggy implementation of the Universal Plug and Play protocol built into Broadcom chipsets used in vulnerable devices. An advisory released in January 2013 warned that the critical flaw affected routers from a raft of manufacturers, including Broadcom, Asus, Cisco, TP-Link, Zyxel, D-Link, Netgear, and US Robotics. The finding from Netlab 360 suggests that many vulnerable devices were allowed to run without ever being patched or locked down through other means. Last week's report documents 116 different types of devices that make up the botnet from a diverse group of manufacturers. Once under the attackers' control, the routers connect to a variety of well-known email services. This is a strong indication that the infected devices are being used to send spam or other types of malicious mail. -
MikroTik Routers Are Forwarding Owners' Traffic To Unknown Attackers (bleepingcomputer.com)
Attackers have been exploiting vulnerabilities in MikroTik routers to forward network traffic to a handful of IP addresses under their control. "The bug is in Winbox management component and allows a remote attacker to bypass authentication and read arbitrary files," reports Bleeping Computer. "Exploit code is freely available from at least three sources from at least three sources." From the report: 360Netlab announced in a blog post today that more than 7,500 MikroTik routers across the world are currently delivering their TZSP (TaZmen Sniffer Protocol) traffic to nine external IP addresses. According to the researchers, the attacker modified the device's packet sniffing settings to forward the data to their locations. "37.1.207.114 is the top player among all the attackers. A significant number of devices have their traffic going to this destination," Qihoo experts inform.
The analysis shows that the attacker is particularly interested in ports 20, 21, 25, 110, and 144, which are for FTP-data, FTP, SMTP, POP3, and IMAP traffic. An unusual interest is in traffic from SNMP (Simple Network Management Protocol) ports 161 and 162, which researchers cannot explain at the moment. The largest number of compromised devices, 1,628, is in Russia, followed by Iran (637), Brazil (615), India (594) and Ukraine (544). The researchers say that security outfits in the affected countries can contact them at netlab[at]360.cn for a full list of IPs. -
'Drupalgeddon2' Touches Off Arms Race To Mass-Exploit Powerful Web Servers (arstechnica.com)
Researchers with Netlab 360 warn that attackers are mass-exploiting "Drupalgeddon2," the name of an extremely critical vulnerability Drupal maintainers patched in late March. The exploit allows them to take control of powerful website servers. Ars Technica reports: Formally indexed as CVE- 2018-7600, Drupalgeddon2 makes it easy for anyone on the Internet to take complete control of vulnerable servers simply by accessing a URL and injecting publicly available exploit code. Exploits allow attackers to run code of their choice without having to have an account of any type on a vulnerable website. The remote-code vulnerability harkens back to a 2014 Drupal vulnerability that also made it easy to commandeer vulnerable servers.
Drupalgeddon2 "is under active attack, and every Drupal site behind our network is being probed constantly from multiple IP addresses," Daniel Cid, CTO and founder of security firm Sucuri, told Ars. "Anyone that has not patched is hacked already at this point. Since the first public exploit was released, we are seeing this arms race between the criminals as they all try to hack as many sites as they can." China-based Netlab 360, meanwhile, said at least three competing attack groups are exploiting the vulnerability. The most active group, Netlab 360 researchers said in a blog post published Friday, is using it to install multiple malicious payloads, including cryptocurrency miners and software for performing distributed denial-of-service attacks on other domains. The group, dubbed Muhstik after a keyword that pops up in its code, relies on 11 separate command-and-control domains and IP addresses, presumably for redundancy in the event one gets taken down. -
Massive DDOS Attacks Are Now Targeting Google, Amazon, and the NRA (pcmag.com)
PC Magazine reports: A new way to amplify DDoS attacks has been spotted harassing Google, Amazon, Pornhub and even the National Rifle Association's main website after striking Github last week. The attacks, which exploit vulnerable "memcached servers," have been trying to hose down scores of new targets with a flood of internet traffic, according to Chinese security firm Qihoo 360... Github was the first high-profile victim and suffered a 1.35 Tbps assault -- or what was then the biggest DDoS attack on record. But days later, an unnamed U.S. service provider fended off a separate assault, which measured at 1.7 Tbps. Unfortunately, the amplified DDoS attacks haven't stopped. They've gone on to strike over 7,000 unique IP addresses in the last seven days, Qihoo 360 said in a blog post... Gaming sites including Rockstargames.com, Minecraft.net, and Playstation.net have been among those hit...
The security community is also steadily addressing the linchpin to all the assaults: the vulnerable memcached servers. About 100,000 of these online storage systems were publicly exposed over a week ago. But the server owners have since patched or firewalled about 60,000 of them, Radware security researcher Daniel Smith said. That leaves 40,000 servers open to exploitation. Smith points to how the coding behind the attack technique has started to circulate online through free tools and scripts.
Meanwhile, Slashdot reader darthcamaro shares an article about "the so-call 'kill switch'" that some vendors have been debating: "The 'kill switch' was immediately obvious to everyone who worked on mitigating this DDoS attack," John Graham-Cumming, CTO of CloudFlare said. "We chose not to use or test this method because it would be unethical and likely illegal since it alters the state of a remote machine without authorization." -
New IoT Malware Targets 100,000 IP Cameras Via Known Flaw (csoonline.com)
Researcher Pierre Kim has found a new malware, called Persirai, that has been infecting over 100,000 Chinese-made, internet-connected cameras. According to Trend Micro, the malware has been active since last month and works by exploiting flaws in the cameras that Kim reported back in March. CSO Online reports: At least 1,250 camera models produced by a Chinese manufacturer possess the bugs, the researcher went on to claim. Over a month later in April, Trend Micro noticed a new malware that spreads by exploiting the same products via the recently disclosed flaws. The security firm estimates that about 120,000 cameras are vulnerable to the malware, based on Shodan, a search engine for internet-connected hardware. The Persirai malware is infecting the cameras to form a botnet, or an army of enslaved computers. These botnets can launch DDoS attacks, which can overwhelm websites with internet traffic, forcing them offline. Once Persirai infects, it'll also block anyone else from exploiting the same vulnerabilities on the device. Security firm Qihoo 360 has also noticed the malware and estimated finding 43,621 devices in China infected with it. Interestingly, Persirai borrows some computer code from a notorious malware known as Mirai, which has also been infecting IoT devices, such as DVRs, internet routers, and CCTV cameras, but by guessing the passwords protecting them.
