[Watch Your Back] New Fake Chrome Update Error Attack Targets Your Users
Compromised websites (legitimate sites that have been successfully compromised to support social engineering) are serving visitors fake Google Chrome update error messages.
"Google Chrome users who use the browser regularly should be wary of a new attack campaign that distributes malware by posing as a Google Chrome update error message," Trend Micro warns. "The attack campaign has been operational since February 2023 and has a large impact area."
The message displayed reads, "UPDATE EXCEPTION. An error occurred in Chrome automatic update. Please install the update package manually later, or wait for the next automatic update." A link is provided at the bottom of the bogus error message that takes the user to what\'s misrepresented as a link that will support a Chrome manual update. In fact the link will download a ZIP file that contains an EXE file. The payload is a cryptojacking Monero miner.
A cryptojacker is bad enough since it will drain power and degrade device performance. This one also carries the potential for compromising sensitive information, particularly credentials, and serving as staging for further attacks.
This campaign may be more effective for its routine, innocent look. There are no spectacular threats, no promises of instant wealth, just a notice about a failed update. Users can become desensitized to the potential risks bogus messages concerning IT issues carry with them.
Informed users are the last line of defense against attacks like these. New school security awareness training can help any organization sustain that line of defense and create a strong security culture.

2022-10-06 10:00:00 | 7 Biggest Cybersecurity Threats of the 21st Century (lien direct) | This blog was written by an independent guest blogger. The 21st century has seen a dramatic increase in the number and sophistication of cybersecurity threats. Here are the 7 biggest threats that businesses and individuals need to be aware of. Ransomware as a service In the past few years, ransomware has become one of the most popular tools for cybercriminals. Ransomware as a service (RaaS) is a new business model that allows anyone with little to no technical expertise to launch their own ransomware attacks. All they need is to sign up for a RaaS platform and pay a fee (usually a percentage of the ransom they collect). RaaS is a growing threat because it makes it easy for anyone to launch attacks. Cybercriminals can target any organization, no matter its size or resources. And, because RaaS platforms typically take care of all the technical details, ransomware attacks can be launched with little effort. In the past several years, there have been a number of high-profile ransomware attacks that have made headlines. In May 2017, the WannaCry ransomware attack affected more than 200,000 computers in 150 countries. The attack caused billions of dollars in damage and disrupted critical infrastructure, such as hospitals and banks. In December 2017, the NotPetya ransomware attack hit more than 10,000 organizations in over 60 countries. The attack caused billions of dollars in damage and disrupted critical infrastructure, such as hospitals and banks. Ransomware attacks have become more sophisticated and targeted. Cybercriminals are now using RaaS platforms to launch targeted attacks against specific organizations. These attacks are often called "spear phishing" attacks because they use carefully crafted emails to trick people into clicking on malicious links or opening attachments that install ransomware on their computers. Organizations of all sizes need to be aware of the threat of ransomware and take steps to protect themselves. This includes having a robust backup and recovery plan in place in case of an attack. Internet of Things The Internet of Things (IoT) is a network of physical devices, vehicles, home appliances, and other items that are embedded with electronics, software, sensors, and connectivity enabling these objects to connect and exchange data. The IoT is a growing market with more and more devices being connected to the internet every day. However, this also creates new security risks. Because IoT devices are often connected to the internet, they can be hacked and used to launch attacks. In October 2016, a massive Distributed Denial of Service (DDoS) attack was launched against the Dyn DNS service using a network of IoT devices that had been infected with the Mirai malware. The attack caused widespread internet disruptions and took down major websites, such as Twitter and Netflix. The IoT presents a unique challenge for security because there are so many different types of devices that can be connected to the internet. Each type of device has its own security risks and vulnerabilities. And, as the number of IoT devices continues to grow, so do the opportunities for cybercriminals to exploit them. Cloud security The cloud has become an essential part of business for many organizations. It offers a number of advantages, such as flexibility, scalability, and cost savings. However, the cloud also creates new security risks. One of the biggest security risks associated with the cloud is data breaches. Because data is stored remotely on servers, it is more vulnerable to attack. In addition, cloud service providers often have access to customer data, which creates another potential point of entry for hackers. Another security risk associated with the | Ransomware Malware Threat | NotPetya NotPetya Wannacry Wannacry | |

2022-08-18 08:00:00 | Ukraine and the fragility of agriculture security (lien direct) |  By Joe Marshall.The war in Ukraine has had far-reaching global implications and one of the most immediate effects felt will be on the global supply chain for food. This war-induced fragility has exposed the weaknesses of how we feed ourselves globally. Ransomware cartels and other adversaries are well aware of this and are actively exploiting that fragility. For the past six years, Cisco Talos has been actively involved in assisting public and private institutions in Ukraine to defend themselves against state-sponsored actors. Our involvement stretches the gamut from commercial to critical infrastructure, to election security. Our presence has afforded us unique opportunities and observations about cybersecurity in a macro and micro way. Ukraine has been a frequent victim of state-sponsored cyber attacks aimed at critical infrastructures like power and transportation. Talos is proud to stand with our partners in Ukraine and help defend their critical networks and help users there maintain access to necessary services. Now that Russia has invaded Ukraine, those threats have escalated to kinetic attacks that are wreaking havoc on a critical element of our world: agriculture and our global food supply chain. Even worse is the implications this war will have for future cyber attacks, as fragility is considered a lucrative element in deciding victimology by threat actors like ransomware cartels. To truly grasp the implications of the war in Ukraine, we have to examine how vital Ukrainian agriculture feeds the world, the current state of affairs, and what this means for the global cybersecurity posture to protect agricultural assets. Where there is weakness, there is opportunityRansomware cartels and their affiliates are actively targeting the agricultural industry. Moreover, these actors have done their homework and are targeting agricultural companies during the two times of the year where they cannot suffer disruptions: planting and harvesting. Per the published FBI PIN Alert: “Cyber actors may perceive cooperatives as lucrative targets with a willingness to pay due to the time-sensitive role they play in agricultural production.” This is far from unusual for these adversaries - they are shrewd and calculating, and understand their victims' weaknesses and industries.

2022-06-27 02:00:00 | 5 years after NotPetya: Lessons learned (lien direct) | On June 27, 2017, the eve of Ukraine's Constitution Day holiday, a major global cyberattack was launched, infecting more than 80 companies in that country using a brand-new cyber pathogen that became known as NotPetya. NotPetya didn't stay within Ukraine's borders but spilled out to infect and cause havoc for thousands of organizations across Europe and worldwide.NotPetya was so named because it was similar to but different from Petya, a self-propagating ransomware virus discovered in 2016 that, unlike other nascent forms of ransomware at the time, was incapable of being decrypted. In another departure from the earlier forms of ransomware, Petya also overwrote and encrypted master boot records and was, therefore, considered more a form of wiper malware than bona fide ransomware.To read this article in full, please click here | Ransomware Malware | NotPetya NotPetya | |

Windows Vulnerability With New Public Exploits Lets You Become Admin
(published: January 29, 2022)
A new vulnerability, tracked as CVE-2022-21882 was discovered by researcher RyeLv in early January 2022. The exploit is a bypass to a previous vulnerability, CVE-2021-1732, and affects all Windows 10 machines that have not applied January’s Patch Tuesday patch. This vulnerability is a privilege escalation exploit, which grants administrator level privileges and allows for the creation of new admin accounts, as well as lateral movement. The exploit abuses a flaw in the manner in which the kernel handles callbacks, changing the flag ConsoleWindow. This will modify the window type, and tricks the system into thinking tagWND.WndExtra is an offset of the kernel desktop heap, thereby granting administrator level read and write access.
Analyst Comment: Apply patches when they become available to keep your systems and assets protected from the latest attacks and vulnerabilities. This is essential when new vulnerabilities are discovered as threat actors will actively attempt to exploit them. A strong patch management policy combined with an effective asset management policy will assist you in keeping your assets up to date and protected.

Shipment-Delivery Scams Become the Favored Way to Spread Malware
(published: January 28, 2022)
Researchers at Cofense and Checkpoint have documented a series of Phishing campaigns throughout Q4 of 2021. The campaign imitates large known delivery brands such as DHL or the US postal service, and aims to abuse the trust these companies have associated with them to manipulate their targets into clicking malicious links or files. The most prominent tactic is to provide a link to a missed package, capitalizing on current global supply chain issues. Once clicked, TrickBot malware is delivered, though other campaigns are delivering as of yet non-attributed trojans. The malicious links in these campaigns are not particularly sophisticated, and are easily identified as false as they lead to domains outside the company they are targeting.
Analyst Comment: Never click on attachments or links from untrustworthy sources, and verify with the legitimate sender the integrity of these emails. Treat any email that attempts to scare, coerce, provide a time limit or force you to click links or attachments with extreme suspicion.

2021-02-28 20:05:19 | We are living in 1984 (ETERNALBLUE) (lien direct) | In the book 1984, the protagonist questions his sanity, because his memory differs from what appears to be everybody else's memory.The Party said that Oceania had never been in alliance with Eurasia. He, Winston Smith, knew that Oceania had been in alliance with Eurasia as short a time as four years ago. But where did that knowledge exist? Only in his own consciousness, which in any case must soon be annihilated. And if all others accepted the lie which the Party imposed-if all records told the same tale-then the lie passed into history and became truth. 'Who controls the past,' ran the Party slogan, 'controls the future: who controls the present controls the past.' And yet the past, though of its nature alterable, never had been altered. Whatever was true now was true from everlasting to everlasting. It was quite simple. All that was needed was an unending series of victories over your own memory. 'Reality control', they called it: in Newspeak, 'doublethink'.I know that EternalBlue didn't cause the Baltimore ransomware attack. When the attack happened, the entire cybersecurity community agreed that EternalBlue wasn't responsible.But this New York Times article said otherwise, blaming the Baltimore attack on EternalBlue. And there are hundreds of other news articles [eg] that agree, citing the New York Times. There are no news articles that dispute this.In a recent book, the author of that article admits it's not true, that EternalBlue didn't cause the ransomware to spread. But they defend themselves as it being essentially true, that EternalBlue is responsible for a lot of bad things, even if technically, not in this case. Such errors are justified, on the grounds they are generalizations and simplifications needed for the mass audience.So we are left with the situation Orwell describes: all records tell the same tale -- when the lie passes into history, it becomes the truth.Orwell continues:He wondered, as he had many times wondered before, whether he himself was a lunatic. Perhaps a lunatic was simply a minority of one. At one time it had been a sign of madness to believe that the earth goes round the sun; today, to believe that the past is inalterable. He might be ALONE in holding that belief, and if alone, then a lunatic. But the thought of being a lunatic did not greatly trouble him: the horror was that he might also be wrong.I'm definitely a lunatic, alone in my beliefs. I sure hope I'm not wrong. Update: Other lunatics document their struggles with Minitrue: When I was investigating the TJX breach, there were NYT articles citing unnamed sources that were made up & then outlets would publish citing the NYT. The TJX lawyers would require us to disprove the articles. Each time we would. It was maddening fighting lies for 8 months.— Nicholas J. Percoco (@c7five) March 1, 2021 |

2020-07-19 17:07:57 | How CEOs think (lien direct) | Recently, Twitter was hacked. CEOs who read about this in the news ask how they can protect themselves from similar threats. The following tweet expresses our frustration with CEOs, that they don't listen to their own people, but instead want to buy a magic pill (a product) or listen to outside consultants (like Gartner). In this post, I describe how CEOs actually think.CEO : "I read about that Twitter hack. Can that happen to us?"Security : "Yes, but ..."CEO : "What products can we buy to prevent this?"Security : "But ..."CEO : "Let's call Gartner."*sobbing sounds*- Wim Remes (@wimremes) July 16, 2020The only thing more broken than how CEOs view cybersecurity is how cybersecurity experts view cybersecurity. We have this flawed view that cybersecurity is a moral imperative, that it's an aim by itself. We are convinced that people are wrong for not taking security seriously. This isn't true. Security isn't a moral issue but simple cost vs. benefits, risk vs. rewards. Taking risks is more often the correct answer rather than having more security.Rather than experts dispensing unbiased advice, we've become advocates/activists, trying to convince people that they need to do more to secure things. This activism has destroyed our credibility in the boardroom. Nobody thinks we are honest.Most of our advice is actually internal political battles. CEOs trust outside consultants mostly because outsiders don't have a stake in internal politics. Thus, the consultant can say the same thing as what you say, but be trusted.CEOs view cybersecurity the same way they view everything else about building the business, from investment in office buildings, to capital equipment, to HR policies, to marketing programs, to telephone infrastructure, to law firms, to .... everything.They divide their business into two parts:The first is the part they do well, the thing they are experts at, the things that define who they are as a company, their competitive advantage.The second is everything else, the things they don't understand.For the second part, they just want to be average in their industry, or at best, slightly above average. They want their manufacturing costs to be about average. They want the salaries paid to employees to be about average. They want the same video conferencing system as everybody else. Everything outside of core competency is average.I can't express this enough: if it's not their core competency, then they don't want to excel at it. Excelling at a thing comes with a price. They have to pay people more. They have to find the leaders with proven track records at excelling at it. They have to manage excellence.This goes all the way to the top. If it's something the company is going to excel at, then the CEO at the top has to have enough expertise themselves to understand who the best leaders to can accomplish this goal. The CEO can't hire an excellent CSO unless they have enough competency to judge the qualifications of the CSO, and enough competency to hold the CSO accountable for the job they are doing.All this is a tradeoff. A focus of attention on one part of the business means less attention on other parts of the business. If your company excels at cybersecurity, it means not excelling at some other part of the business.So unless you are a company like Google, whose cybersecurity is a competitive advantage, you don't want to excel in cybersecurity.

2019-05-29 20:16:09 | Your threat model is wrong (lien direct) | Several subjects have come up with the past week that all come down to the same thing: your threat model is wrong. Instead of addressing the the threat that exists, you've morphed the threat into something else that you'd rather deal with, or which is easier to understand.PhishingAn example is this question that misunderstands the threat of "phishing":Should failing multiple phishing tests be grounds for firing? I ran into a guy at a recent conference, said his employer fired people for repeatedly falling for (simulated) phishing attacks. I talked to experts, who weren't wild about this disincentive. https://t.co/eRYPZ9qkzB pic.twitter.com/Q1aqCmkrWL- briankrebs (@briankrebs) May 29, 2019The (wrong) threat model is here is that phishing is an email that smart users with training can identify and avoid. This isn't true.Good phishing messages are indistinguishable from legitimate messages. Said another way, a lot of legitimate messages are in fact phishing messages, such as when HR sends out a message saying "log into this website with your organization username/password".Recently, my university sent me an email for mandatory Title IX training, not digitally signed, with an external link to the training, that requested my university login creds for access, that was sent from an external address but from the Title IX coordinator.- Tyler Pieron (@tyler_pieron) May 29, 2019Yes, it's amazing how easily stupid employees are tricked by the most obvious of phishing messages, and you want to point and laugh at them. But frankly, you want the idiot employees doing this. The more obvious phishing attempts are the least harmful and a good test of the rest of your security -- which should be based on the assumption that users will frequently fall for phishing.In other words, if you paid attention to the threat model, you'd be mitigating the threat in other ways and not even bother training employees. You'd be firing HR idiots for phishing employees, not punishing employees for getting tricked. Your systems would be resilient against successful phishes, such as using two-factor authentication.IoT securityAfter the Mirai worm, government types pushed for laws to secure IoT devices, as billions of insecure devices like TVs, cars, security cameras, and toasters are added to the Internet. Everyone is afraid of the next Mirai-type worm. For example, they are pushing for devices to be auto-updated.But auto-updates are a bigger threat than worms.Since Mirai, roughly 10-billion new IoT devices have been added to the Internet, yet there hasn't been a Mirai-sized worm. Why is that? After 10-billion new IoT devices, it's still Windows and not IoT that is the main problem.The answer is that number, 10-billion. Internet worms work by guessing IPv4 addresses, of which there are only 4-billion. You can't have 10-billion new devices on the public IPv4 addresses because there simply aren't enough addresses. Instead, those 10-billion devices are almost entirely being put on private ne | Ransomware Tool Vulnerability Threat Guideline | FedEx NotPetya | |

2019-05-28 06:20:06 | Almost One Million Vulnerable to BlueKeep Vuln (CVE-2019-0708) (lien direct) | Microsoft announced a vulnerability in it's "Remote Desktop" product that can lead to robust, wormable exploits. I scanned the Internet to assess the danger. I find nearly 1-million devices on the public Internet that are vulnerable to the bug. That means when the worm hits, it'll likely compromise those million devices. This will likely lead to an event as damaging as WannaCry and notPetya from 2017 -- potentially worse, as hackers have since honed their skills exploiting these things for ransomware and other nastiness.To scan the Internet, I started with masscan, my Internet-scale port scanner, looking for port 3389, the one used by Remote Desktop. This takes a couple hours, and lists all the devices running Remote Desktop -- in theory.This returned 7,629,102 results (over 7-million). However, there is a lot of junk out there that'll respond on this port. Only about half are actually Remote Desktop.Masscan only finds the open ports, but is not complex enough to check for the vulnerability. Remote Desktop is a complicated protocol. A project was posted that could connect to an address and test it, to see if it was patched or vulnerable. I took that project and optimized it a bit, rdpscan, then used it to scan the results from masscan. It's a thousand times slower, but it's only scanning the results from masscan instead of the entire Internet.The table of results is as follows:1447579 UNKNOWN - receive timeout1414793 SAFE - Target appears patched1294719 UNKNOWN - connection reset by peer1235448 SAFE - CredSSP/NLA required 923671 VULNERABLE -- got appid 651545 UNKNOWN - FIN received 438480 UNKNOWN - connect timeout 105721 UNKNOWN - connect failed 9 82836 SAFE - not RDP but HTTP 24833 UNKNOWN - connection reset on connect 3098 UNKNOWN - network error 2576 UNKNOWN - connection terminatedThe various UNKNOWN things fail for various reasons. A lot of them are because the protocol isn't actually Remote Desktop and respond weirdly when we try to talk Remote Desktop. A lot of others are Windows machines, sometimes vulnerable and sometimes not, but for some reason return errors sometimes.The important results are those marked VULNERABLE. There are 923,671 vulnerable machines in this result. That means we've confirmed the vulnerability really does exist, though it's possible a small number of these are "honeypots" deliberately pretending to be vulnerable in order to monitor hacker activity on the Internet.The next result are those marked SAFE due to probably being "pached". Actually, it doesn't necessarily mean they are patched Windows boxes. They could instead be non-Windows systems that appear the same as patched Windows boxes. But either way, they are safe from this vulnerability. There are 1,414,793 of them.The next result to look at are those marked SAFE due to CredSSP/NLA failures, of which there are 1,235,448. This doesn't mean they are patched, but only that we can't exploit them. They require "network level authentication" first before we can talk Remote Desktop to them. That means we can't test whether they are patched or vulnerable -- but neither can the hackers. They may still be exploitable via an insider threat who knows a valid username/password, but they aren't exploitable by anonymous hackers or worms.The next category is marked as SAFE because they aren't Remote Desktop at all, but HTTP servers.

2019-05-27 19:59:38 | A lesson in journalism vs. cybersecurity (lien direct) | A recent NYTimes article blaming the NSA for a ransomware attack on Baltimore is typical bad journalism. It's an op-ed masquerading as a news article. It cites many to support the conclusion the NSA is to be blamed, but only a single quote, from the NSA director, from the opposing side. Yet many experts oppose this conclusion, such as @dave_maynor, @beauwoods, @daveaitel, @riskybusiness, @shpantzer, @todb, @hrbrmst, ... It's not as if these people are hard to find, it's that the story's authors didn't look.The main reason experts disagree is that the NSA's Eternalblue isn't actually responsible for most ransomware infections. It's almost never used to start the initial infection -- that's almost always phishing or website vulns. Once inside, it's almost never used to spread laterally -- that's almost always done with windows networking and stolen credentials. Yes, ransomware increasingly includes Eternalblue as part of their arsenal of attacks, but this doesn't mean Eternalblue is responsible for ransomware.The NYTimes story takes extraordinary effort to jump around this fact, deliberately misleading the reader to conflate one with the other. A good example is this paragraph: That link is a warning from last July about the "Emotet" ransomware and makes no mention of EternalBlue. Instead, the story is citing anonymous researchers claiming that EthernalBlue has been added to Emotet since after that DHS warning.Who are these anonymous researchers? The NYTimes article doesn't say. This is bad journalism. The principles of journalism are that you are supposed to attribute where you got such information, so that the reader can verify for themselves whether the information is true or false, or at least, credible.And in this case, it's probably false. The likely source for that claim is this article from Malwarebytes about Emotet. They have since retracted this claim, as the latest version of their article points out. In any event, the NYTimes article claims that Emotet is now "relying" on the NSA's EternalBlue to spread. That's not the same thing as "using", not even close. Yes, lots of ransomware has been updated to also use Eternalblue to spread. However, what ransomware is relying upon is still the Wind |

2018-06-27 15:49:15 | Lessons from nPetya one year later (lien direct) | This is the one year anniversary of NotPetya. It was probably the most expensive single hacker attack in history (so far), with FedEx estimating it cost them $300 million. Shipping giant Maersk and drug giant Merck suffered losses on a similar scale. Many are discussing lessons we should learn from this, but they are the wrong lessons.An example is this quote in a recent article:"One year on from NotPetya, it seems lessons still haven't been learned. A lack of regular patching of outdated systems because of the issues of downtime and disruption to organisations was the path through which both NotPetya and WannaCry spread, and this fundamental problem remains." This is an attractive claim. It describes the problem in terms of people being "weak" and that the solution is to be "strong". If only organizations where strong enough, willing to deal with downtime and disruption, then problems like this wouldn't happen.But this is wrong, at least in the case of NotPetya.NotPetya's spread was initiated through the Ukraining company MeDoc, which provided tax accounting software. It had an auto-update process for keeping its software up-to-date. This was subverted in order to deliver the initial NotPetya infection. Patching had nothing to do with this. Other common security controls like firewalls were also bypassed.Auto-updates and cloud-management of software and IoT devices is becoming the norm. This creates a danger for such "supply chain" attacks, where the supplier of the product gets compromised, spreading an infection to all their customers. The lesson organizations need to learn about this is how such infections can be contained. One way is to firewall such products away from the core network. Another solution is port-isolation/microsegmentation, that limits the spread after an initial infection.Once NotPetya got into an organization, it spread laterally. The chief way it did this was through Mimikatz/PsExec, reusing Windows credentials. It stole whatever login information it could get from the infected machine and used it to try to log on to other Windows machines. If it got lucky getting domain administrator credentials, it then spread to the entire Windows domain. This was the primary method of spreading, not the unpatched ETERNALBLUE vulnerability. This is why it was so devastating to companies like Maersk: it wasn't a matter of a few unpatched systems getting infected, it was a matter of losing entire domains, including the backup systems.Such spreading through Windows credentials continues to plague organizations. A good example is the recent ransomware infection of the City of Atlanta that spread much the same way. The limits of the worm were the limits of domain trust relationships. For example, it didn't infect the city airport because that Windows domain is separate from the city's domains.This is the most pressing lesson organizations need to learn, the one they are ignoring. They need to do more to prevent desktops from infecting each other, such as through port-isolation/microsegmentation. They need to control the spread of administrative credentials within the organization. A lot of organizations put the same local admin account on every workstation which makes the spread of NotPetya style worms trivial. They need to reevaluate trust relationships between domains, so that the admin of one can't infect the others.These solutions are difficult, which is why news articles don't mention them. You don't have to know anything about security to proclaim "the problem is lack of patches". It's moral authority, chastising the weak, rather than a proscription of what to do. Solving supply chain hacks and Windows credential sharing, though, is hard. I don't know any universal solution to this -- I'd have to thoroughly analyze your network and business in order to | Ransomware Malware Patching | FedEx NotPetya Wannacry |
