"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.

When Russia launched wide-ranging cyber-attacks while its army invaded Ukraine, it also deployed waves of wiper malware to destroy data. The first wave targeted the data on the disks. As Ukraine fortified its defenses in that area, the second wave left the data on the disks alone and went after the metadata. The third wave bypassed the two previous targets and attacked the file systems. As depicted in global news and during sessions of the RSA conference, this was a very methodical and effective approach designed to inflict maximum amounts of damage, and it reflects the methodical, often relentless, attack approaches shaping the threat landscape. In particular, as organizations fortify their defenses, adversaries will continue to focus on trust to gain access, using your partners, your vendors, and your employees against you. What does this mean for enterprise users? As we discussed in our previous post on cyber threats, organizations must find new and novel defenses against adversaries who increasingly shift tactics. As adversaries become more nuanced, we must understand their moves and motivations to try to get one step ahead of them. Let’s Recap: Several high-profile security incidents in the recent past altogether grimly encapsulate the myriad challenges companies now face. NotPetya, the most expensive cyber incident in history, demonstrated how attackers are masquerading their efforts. NotPetya targeted a tax software company in Ukraine in 2017. At first, the effort appeared to be ransomware. However, its intent was purely destructive as it was designed to inflict damage as quickly and effectively as possible. The C Cleaner attack, a few months later, demonstrated how complex and patient actors who were focused on IP level threats had become. The targets were system administrative tools that, if compromised, already had an increased level of access. C Cleaner showed that all software supply chain attacks aren’t created equal. It’s dependent on the level of access of the systems and the users that you’re compromising. Some 3 million versions of the compromised C Cleaner software were downloaded. However, only 50 of the downloaded software received additional payloads. This was an adversary that was willing to compromise more than 3 million systems to just get a foothold into 50. This gives you a clear idea of the challenges that we face as enterprises from these types of sophisticated actors. Attackers are also being more flagrant and doing a better job of covering their tracks. In the past, nation states focused on covert activities. Olympic Destroyer, which targeted the 2018 Olympics in South Korea, showed how attacks are now being brought to the public eye. False flags, tactics applied to deceive or misguide attribution attempts, were also put into Olympic Destroyer. Six months after the attack, it was attributed to multiple different nations, because such care had been put into throwing off attribution. More recently, VPN Filter/Cyber Blink demonstrated how adversaries are targeting different types of equipment. While attacks have historically focused on office equipment, these incidents shifted to home routers, in tandem with the increase in remote work. At home, people often use combination modem routers. These devices challenge detection capabilities. A foothold into home routers also allows actors to analyze all traffic moving in and out of the network. It’s incredibly difficult to detect an attack. You have to treat a home Wi-Fi like a public Wi-Fi at a coffee shop. Threat actors are targeting the foundational infrastructure of the internet as well. Sea T	Malware Tool Threat	NotPetya NotPetya

	2019-12-03 17:12:11	NBlog Dec 3 - infosec driving principles (lien direct)	In an interview for CIO Dive, Maersk's recently-appointed CISO Andy Powell discussed aligning the organization with these five 'key operating principles':"The first is trust. The client has got to trust us with their data, to trust us to look at their business. So we've got to build trust through the cybersecurity solutions that we put in place. That is absolutely fundamental. So client trust, client buy-in has been fundamental to what we tried to drive as a key message. The second is resilience. Because you've got to have resilient systems because clients won't give you business if you're not resilient ... The third really is around the fact that security is everybody's responsibility. And we push that message really hard across the company … be clear about what you need to do and we train people accordingly. ...The fourth one really is accountability of security and I have pushed accountability for cyber risk to the business. ... And the final piece, and this has been one of the big call outs of my team to everybody, is that security is a benefit, not a burden. The reason I say that is people's perception is that security will slow things down, will get in the way ... the reality is that if you involve security early enough, you can build solutions that actually attract additional clients."Fair enough Andy. I wouldn't particularly quarrel with any of them, but as to whether they would feature in my personal top-five I'm not so sure. Here are five others they'd be competing against, with shipping-related illustrations just for fun:Governance involves structuring, positioning, setting things up and guiding the organization in the right overall direction - determining then plotting the optimal route to the ship's ultimate destination, loading up with the right tools, people and provisions. Corporate governance necessarily involves putting things in place for both protecting and exploiting information, a vital and valuable yet vulnerable business asset;Information is subject to risks that can and probably should be managed proactively, just as a ship's captain doesn't merely accept the inclement weather and various other hazards but, where appropriate, actively mitigates or avoids them, dynamically reacting and adjusting course as things change;Flexibility and responsiveness, along with resilience and ro	Tool Guideline	NotPetya

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
