      Your Asus router may be compromised – here’s how to tell and what to do

      by

      Elyse Betters Picaro / ZDNETDo you own an Asus router? If so, your device may have been one of thousands compromised in a large campaign waged by cybercriminals looking to exploit it. In a blog post published Wednesday, security firm GreyNoise revealed that the attack was staged by what it suggests is “a well-resourced and highly capable adversary.”Also: Massive data breach exposes 184 million passwords for Google, Microsoft, Facebook, and moreTo gain initial access, the attackers used brute-force login techniques and two different methods to bypass the built-in authentication. They’ve also been able to exploit certain vulnerabilities not yet assigned official CVE numbers. Once they’d accessed the router, they were able to run arbitrary system commands by exploiting a known security flaw identified as CVE-2023-39780.Though no malware was actually installed, the attackers certainly left their mark. More than 9,000 Asus routers affectedBy using built-in Asus settings, they were able to set up SSH access, a secure way to connect to and control a remote device. They also installed a backdoor to return easily to the router’s firmware without worrying about authentication. The backdoor was stored in non-volatile memory (NVRAM), which meant it couldn’t be removed by rebooting the router or updating its firmware. To avoid being caught, the criminals even disabled logging, which would otherwise record their access. Also: Why no small business is too small for hackers – and 8 security best practices for SMBsBased on data from internet scanner Censys, more than 9,000 Asus routers are affected, and that number is growing. However, GreyNoise said that over the past three months, it witnessed only 30 related requests to access the affected routers. That seems to be a sign that the campaign is moving along slowly and quietly. If no malware is installed, what’s the goal behind the attack? “This appears to be part of a stealth operation to assemble a distributed network of backdoor devices — potentially laying the groundwork for a future botnet,” GreyNoise said in its post.And who’s behind it?”The tactics used in this campaign — stealthy initial access, use of built-in system features for persistence, and careful avoidance of detection — are consistent with those seen in advanced, long-term operations, including activity associated with advanced persistent threat (APT) actors and operational relay box (ORB) networks. While GreyNoise has made no attribution, the level of tradecraft suggests a well-resourced and highly capable adversary.” Also: Your old router could be a security threat – here’s why and what to doThe language used by GreyNoise, particularly the reference to APTs, suggests a nation-state or attackers working on behalf of a hostile government. Though GreyNoise didn’t cite any particular adversary, such attacks have been attributed to different countries, including China, Russia, North Korea, and Iran.Using its AI-powered payload analysis tool Sift and its observation grid, GreyNoise discovered the attack on March 18. But the firm said it waited until now to disclose it publicly so it could have time to consult with its government and industry partners. More

Cybersecurity researcher Jeremiah Fowler revealed his discovery of a massive online database containing more than 184 million unique account credentials, in a report published Thursday. Usernames, passwords, emails, and URLs for a host of applications […] More

      7 ways to thwart phone thieves – and avoid China’s infamous ‘stolen iPhone building’

      by

      Sabrina Ortiz/ZDNETA thief who steals your smartphone can try to crack it themselves, sell it locally, or use it to commit fraud. But your stolen phone could also travel as far away as China. A recent investigation by The Financial Times (paywall) found that a particular building in Shenzhen’s Huaqiangbei district is home to a treasure trove of second-hand iPhones, including stolen devices.Though several locations in and around the Huaqiangbei district are hot spots for trading used phones, FT’s investigation focused mostly on the Feiyang Times building. Much of the buying and selling here is for phones that were legitimately traded in by their owners, according to the reporter who covered the action. But at least some of the activity involves stolen phones, leading the Feiyang Times to be known as China’s “stolen iPhone building.” Also: 5 warning signs that your phone’s been hacked – and how to fight backThe Times relates one unfortunate individual whose iPhone 15 Pro was stolen by thieves in London. Using tracking technology, the victim followed the phone to its final destination in the Huaqiangbei district. After sharing his experience on LinkedIn, he discovered that many other people had encountered similar situations. A woman in North Carolina whose phone was stolen tracked it on its journey from Charlotte to Miami and then finally to Shenzhen, according to WRAL News. In this case, the thieves compounded the crime with a spin on the usual ransomware ploy. In texts sent to the woman, they told her that unless she deactivated the stolen phone, they would sell her private information on the black market, meaning the dark web. Phone theft is on the rise, especially in major cities like London, Paris, and New York. In February, the UK’s Metropolitan Police said that phone theft in London is a business that generates £50 million ($67 million) per year. In one week, UK police officials captured 1,000 stolen devices and made 230 arrests, FT reported. More
