Sophos 2019 Threat Report shows the rise of hand-delivered, targeted cyberattacks
Sophos has launched its 2019 Threat Report providing insights into emerging and evolving cybersecurity trends.
The report, produced by SophosLabs researchers, explores changes in the threat landscape over the past 12 months, uncovering trends and how they are expected to impact cybersecurity in 2019.
“The threat landscape is undoubtedly evolving; less skilled cyber criminals are being forced out of business, the fittest among them step up their game to survive and we’ll eventually be left with fewer, but smarter and stronger, adversaries. These new cybercriminals are effectively a cross-breed of the once esoteric, targeted attacker, and the pedestrian purveyor of off-the-shelf malware, using manual hacking techniques, not for espionage or sabotage, but to maintain their dishonorable income streams.” – Joe Levy, CTO, Sophos, as referenced in the SophosLabs 2019 Threat Report
The SophosLabs 2019 Threat Report focuses on these key cybercriminal behaviours and attacks:
- Capitalist cybercriminals are turning to targeted ransomware attacks that are premeditated and reaping millions of dollars in ransom – 2018 saw the advancement of hand-delivered, targeted ransomware attacks that are earning cybercriminals millions of dollars.
- These attacks are different than ‘spray and pray’ style attacks that are automatically distributed through millions of emails. Targeted ransomware is more damaging than if delivered from a bot, as human attackers can find and stake out victims, think laterally, trouble shoot to overcome roadblocks, and wipe out back-ups so the ransom must be paid.
- This “interactive attack style,” where adversaries manually maneuver through a network step-by-step, is now increasing in popularity. Sophos experts believe the financial success of SamSam, BitPaymer and Dharma to inspire copycat attacks and expect more happen in 2019.
- Cybercriminals are using readily available Windows systems administration tools – This year’s report uncovers a shift in threat execution, as more mainstream attackers now employ Advanced Persistent Threat (APT) techniques to use readily available IT tools as their route to advance through a system and complete their mission – whether it’s to steal sensitive information off the server or drop ransomware:
- Turning admin tools into cyberattack tools
In an ironic twist, or Cyber Catch-22, cybercriminals are utilising essential or built-in Windows IT admin tools, including Powershell files and Windows Scripting executables, to deploy malware attacks on users. - Cybercriminals are playing Digital Dominos
By chaining together a sequence of different script types that execute an attack at the end of the event series, hackers can instigate a chain reaction before IT managers detect a threat is operational on the network, and once they break in it’s difficult to stop the payload from executing. - Cybercriminals have adopted newer Office exploits to lure in victims
Office exploits have long been an attack vector, but recently cybercriminals have cut loose old Office document exploits in favour of newer ones.
- EternalBlue becomes a key tool for cryptojacking attacks
Patching updates appeared for this Windows threat more than a year ago, yet the EternalBlue exploit is still a favourite of cybercriminals; the coupling of EternalBlue to cryptomining software turned the activity from a nuisance hobby into a potentially lucrative criminal career.
Lateral distribution on the corporate networks allowed the cryptojacker to quickly infect multiple machines, increasing payouts to the hacker and heavy costs to the user.
- The continued threat of mobile and IoT malware – Malware’s impact extends beyond the organization’s infrastructure as we see the threat from mobile malware grow apace. With illegal Android apps on the increase,2018 has seen an increased focus in malware being pushed to phones, tablets and other IoT devices. As homes and businesses adopt more internet-connected devices, criminals have been devising new ways to hijack those devices to use as nodes in huge botnet attacks. In 2018, VPNFilter demonstrated the destructive power of weaponized malware that affects embedded systems and networked devices that have no obvious user interface.
- Elsewhere, Mirai Aidra, Wifatch, and Gafgyt delivered a range of automated attacks that hijacked networked devices to use as nodes in botnets to engage in distributed denial-of-service attacks, mine cryptocurrency and infiltrate networks.
With Black Friday and Cyber Monday around the corner, we’re entering a high-risk period for cybersecurity.
A recent Sophos report highlights that malicious emails were the second most common root cause of ransomware attacks in critical sectors, responsible for 25% of cases.
During peak shopping days, this threat intensifies.
Here’s what happens: with the surge in online deals, more employees may be shopping from their work computers, feeling that Cyber Monday is a legitimate time to do so.
This increases the risk of them clicking more freely and potentially exposing the organization to malicious links or phishing attacks.
To keep your organization safe, encourage your team to follow these simple tips:
• Use an ad blocker – Advertisements are not only tracking your every movement and collecting enough information on your habits to make the FBI blush, but they are also a major source of malicious links and deceptive content on the internet. Not only is your browsing safer, but also faster and uses less bandwidth. Two of our favorites are uBlock Origin and Ghostery.
• Use private browsing or incognito mode – To prevent your shopping habits and interests from following you around from site to site (and potentially revealing what gifts you might be purchasing to others using your device, bonus!), you should enable private browsing (Firefox) or incognito mode (Chrome). This will block tracking cookies and help the internet forget your travels as the waves wash away your footprints in the sand.
• Make your browser “privacy smart” – The Electronic Frontier Foundation (EFF) provides a browser extension called Privacy Badger designed to automatically make all the right choices around browsing whilst maintaining our privacy and blocking invisible trackers.
• Avoid using one account on multiple services – When logging into an e-commerce site it is often tempting to use the “Sign in with Facebook” or “Sign in with Google” button. While it takes a few more minutes to create a new login, it will provide more privacy as you are not sharing all of the sites you shop at with these tech giants.
• Use guest login when available – In addition to letting you use an account from other websites, many have an option to use a guest login rather than creating a new account. This is a great option if you don’t expect to need technical support or to do business on a recurring basis. Fewer passwords, fewer personal details, fewer problems if they get hacked.
• Don’t save card details – Many e-commerce sites will default to storing your credit card information in your profile for your “convenience” (or their hope you’ll shop there again). They can’t lose what they don’t have, so tell them not to store your credit card unless it is absolutely necessary.
• Use temporary card numbers – Many financial institutions now offer temporary or one-time use credit card numbers. You can open the app on your phone or in your browser and get a single-use disposable credit card number preventing card fraud and tracking when merchants share card processors. Sometimes you’re even able to specify a card limit per temporary number to further protect your account.
• Use credit, not debit – All of us need to be wary of overspending during the holidays, but it is best to leave the debit card at home. Credit cards offer significantly more protection against online fraud, and you are in the power position in a dispute. You can simply not pay your bill while disputing the charge, rather than having criminals directly drain your bank account of your hard-earned cash.
• Beware of direct messages via social media/chat apps – With modern generative AI technology it is almost trivial to create an entire fake online store and lure people to share their personal information and payment data with you. It’s safest to shop at established sites or those personally recommended to you by friends and family. Many unsolicited messages lead to data collection or theft.
• Don’t click deals in email that look too good to be true or are from businesses you don’t have accounts from – these could be phishing emails hoping to bait you into clicking links to bogus, malicious web sites.
This season, small steps can make a big difference in protecting against cyber threats.

It’s Cybersecurity Awareness Month and Sophos has Some Tips for You!
In the mood of Cybersecurity Awareness Month, Christopher Budd, Director Sophos X-Ops, has compiled some tips for staying secure online.
Cybersecurity Pro Tips:
- Face Scans and Fingerprints are Safer Than Passcodes: Use features like Face ID or fingerprint scans for your devices as much as possible. These are safer than passcodes and devices have good built-in protections for this sensitive information.
- Use Multi-Factor Authentication: Use multi-factor authentication (MFA) whenever possible. This gives an important extra layer of security that makes it harder for cybercriminals to access your accounts. If you can’t use something more secure like secure authenticator applications or physical hardware security keys, use your phone number — it’s safer than using nothing. If you use MFA for only one thing, use it for your email: that’s what attackers want the most.
- Think Before You Share Publicly: Think twice before sharing any information publicly –cybercriminals can use it to access your accounts or to convince someone that they’re you.
- Think about those cute surveys on Facebook with questions about your first car, city you were born in: these are the same kinds of info cybercriminals can use to pretend they’re you and log into and take over your accounts.
- You Don’t Always Need (to keep) the App: Don’t feel pressured to download an app every time: you can often use the service’s website just as well. Apps collect much more data than websites, including your location, your contact list and other info you might not want to share.If you do download an app, think about deleting it when you’re done using it: you can always reinstall it next time you need it.
- Apps from app stores and websites that aren’t the official big names ones like Google Play, Apple’s App Store, Samsung’s Galaxy Store can be very risky. The official stores have security and privacy standards that can identify malicious activity. Always stick to official sources for downloading apps or, if they’re not on the official app stores, download the app from the developer’s official website or use the app’s web version.
- Be On Your Guard for Unexpected Emails and Text Messages: Phishing continues to be one of the most effective tactics cybercriminals use to compromise consumers. If you get an unexpected email or text message, ignore it or at least don’t interact with it (don’t open attachments, don’t click on links). If you think it might be legitimate, reach out directly to who you think sent it and check with them.
- Question Urgency in Emails and Calls: Cybercriminals use urgency to get you to let your guard down and make bad decisions. If someone contacts you saying they’re from a trusted organization like the IRS, police or your bank and need you to take action quickly or something bad will happen, stop and question it. Go to the trusted source like the number on the back of your credit card to independently validate the request.
- Practice Good Password Security: Every account should have its own unique complex password. A strong password is at least 12 characters long with a mix of numbers, upper- and lower-case letters, and punctuation characters. Passwords should not be based on any personal information, and the best ones use a phrase rather than single words. If these passwords are too tough to juggle, try a password manager to stay organized.
- Keep Everything Updated and Run Security Tools. Make sure all your apps and devices are always fully updated. Be sure to have some sort of security software on all of your phones and computers (even if you have a Mac).
- Get Rid of End-of-Life Devices and Software: Everything from operating systems to services to Wi-Fi routers “go stale” and must be replaced eventually. For example, it might surprise you, but your internet router is typically only supported with patches and updates for a few years after you get it. Attackers love out-of-date devices. When something is “out of support” it’s stale: get rid of it and replace it with something fresh.
- Back Up Your Data: While ransomware groups are mostly after businesses that can pay higher ransoms, they still go after people at home. It’s still important to have your data backed up so that you don’t have to consider paying a ransom.
Put Your Mind at Ease Regarding These Cybersecurity Concerns
Part of staying secure requires being able to filter out the noise and prioritize the security actions that matter. Here are things notto worry about. Focus your energy on real risks, not exaggerated threats.
- Public Wi-Fi is Safer Than You Think: Contrary to outdated advice, public Wi-Fi is generally safe due to encryption used by most websites and apps. Use it freely at airports or coffee shops, but avoid sensitive activities.
- Beware of Fearmongering Around New Tech Features: Not every new technology is as risky as it’s made out to be. For example, Apple’s NameDrop feature is generally safe and requires specific conditions to function. However, if you’re concerned, you can easily turn it off in settings.
Stop Stressing Over Public Chargers: The risk of “juice jacking” (data theft from public chargers) is extremely low. Don’t worry about using public phone chargers — just focus on real, more prevalent threats.
