Top Cyber Stories of the Last Week

  • LastPass Admits Attackers have an Encrypted Copy of Customers’ Password Vaults 

Password locker LastPass has warned customers that the August 2022 attack on its systems saw unknown parties copy encrypted files that contain the passwords to their accounts.

In a December 22nd update to its advice about the incident, LastPass brings customers up to date by explaining that in the August 2022 attack “some source code and technical information were stolen from our development environment and used to target another employee, obtaining credentials and keys which were used to access and decrypt some storage volumes within the cloud-based storage service.” Those creds allowed the attacker to copy information “that contained basic customer account information and related metadata including company names, end-user names, billing addresses, email addresses, telephone numbers, and the IP addresses from which customers were accessing the LastPass service.”

The update reveals that the attacker also copied “customer vault” data, the file LastPass uses to let customers record their passwords. That file “is stored in a proprietary binary format that contains both unencrypted data, such as website URLs, as well as fully-encrypted sensitive fields such as website usernames and passwords, secure notes, and form-filled data.” The passwords are encrypted with “256-bit AES encryption and can only be decrypted with a unique encryption key derived from each user’s master password”.

LastPass’ advice is that even though attackers have that file, customers who use its default settings have nothing to do as a result of this update as “it would take millions of years to guess your master password using generally-available password-cracking technology.” One of those default settings is not to re-use the master password that is required to log into LastPass. The outfit suggests you make it a complex credential and use that password for just one thing: accessing LastPass.

LastPass therefore offered the following advice to individual and business users: If your master password does not make use of the defaults above, then it would significantly reduce the number of attempts needed to guess it correctly. In this case, as an extra security measure, you should consider minimising risk by changing passwords of websites you have stored.

LastPass’s update concludes with news it decommissioned the systems breached in August 2022 and has built new infrastructure that adds extra protections.

  • Ransomware Attacks Increased 41% In November

Ransomware attacks rose 41% last month as groups shifted among the top spots and increasingly leveraged DDoS attacks, according to new research from NCC Group.

A common thread of NCC Group's November Threat Pulse was a "month full of surprises," particularly related to unexpected shifts in threat actor behaviour. The Cuba ransomware gang resurged with its highest number of attacks recorded by NCC Group. Royal replaced LockBit 3.0 as the most active strain, a first since September of last year.

These factors and more contributed to the significant jump in November attacks, which rose from 188 in October to 265.

"For 2022, this increase represents the most reported incidents in one month since that of April, when there were 289 incidents, and is also the largest month-on-month increase since June-July's marginally larger increase of 47%," NCC Group wrote in the report.

Operators behind Royal ransomware, a strain that emerged earlier this year that operates without affiliates and utilises intermittent encryption to evade detection, surpassed LockBit 3.0 for the number one spot, accounting for 16% of hack and leak incidents last month.

  • The Risk of Escalation from Cyber Attacks Has Never Been Greater

In 2022, an American dressed in his pyjamas took down North Korea’s Internet from his living room. Fortunately, there was no reprisal against the United States. But Kim Jong Un and his generals must have weighed retaliation and asked themselves whether the so-called independent hacker was a front for a planned and official American attack.

In 2023, the world might not get so lucky. There will almost certainly be a major cyber attack. It could shut down Taiwan’s airports and trains, paralyse British military computers, or swing a US election. This is terrifying, because each time this happens, there is a small risk that the aggrieved side will respond aggressively, maybe at the wrong party, and (worst of all) even if it carries the risk of nuclear escalation.

This is because cyber weapons are different from conventional ones. They are cheaper to design and wield. That means great powers, middle powers, and pariah states can all develop and use them.

More important, missiles come with a return address, but virtual attacks do not. Suppose in 2023, in the coldest weeks of winter, a virus shuts down American or European oil pipelines. It has all the markings of a Russian attack, but intelligence experts warn it could be a Chinese assault in disguise. Others see hints of the Iranian Revolutionary Guard. No one knows for sure. Presidents Biden and Macron have to decide whether to retaliate at all, and if so, against whom … Russia? China? Iran? It's a gamble, and they could get unlucky.

Neither country wants to start a conventional war with one another, let alone a nuclear one. Conflict is so ruinous that most enemies prefer to loathe one another in peace. During the Cold War, the prospect of mutual destruction was a huge deterrent to any great power war. There were almost no circumstances in which it made sense to initiate an attack. But cyber warfare changes that conventional strategic calculus. The attribution problem introduces an immense amount of uncertainty, complicating the decision our leaders have to make.

  • FBI Recommends Ad Blockers as Cyber Criminals Impersonate Brands in Search Engine Ads

The Federal Bureau of Investigation (FBI) this week raised the alarm on cyber criminals impersonating brands in advertisements that appear in search engine results. The agency has advised consumers to use ad blockers to protect themselves from such threats.

The attackers register domains similar to those of legitimate businesses or services, and use those domains to purchase ads from search engine advertisement services, the FBI says in an alert. These nefarious ads are displayed at the top of the web page when the user searches for that business or service, and the user might mistake them for an actual search result.

Links included in these ads take users to pages that are identical to the official web pages of the impersonated businesses, the FBI explains. If the user searches for an application, they are taken to a fake web page that uses the real name of the program the user searches for, and which contains a link to download software that is, in fact, malware.

“These advertisements have also been used to impersonate websites involved in finances, particularly cryptocurrency exchange platforms,” the FBI notes. Seemingly legitimate exchange platforms, the malicious sites prompt users to provide their login and financial information, which the cyber criminals then use to steal the victim’s funds.

“While search engine advertisements are not malicious in nature, it is important to practice caution when accessing a web page through an advertised link,” the FBI says.

Businesses are advised to use domain protection services to be notified of domain spoofing, and to educate users about spoofed websites and on how to find legitimate downloads for the company’s software.

Users are advised to check URLs to make sure they access authentic websites, to type a business’ URL into the browser instead of searching for that business, and to use ad blockers when performing internet searches. Ad blockers can have a negative impact on the revenues of online businesses and advertisers, but they can be good for online security, and even the NSA and CIA are reportedly using them.

  • North Korea-Linked Hackers Stole $626 Million in Virtual Assets in 2022

South Korea’s spy agency, the National Intelligence Service, estimated that North Korea-linked threat actors have stolen an estimated 1.5 trillion won ($1.2 billion) in cryptocurrency and other virtual assets in the past five years.

According to the spy agency, more than half the crypto assets (about 800 billion won ($626 million)) have been stolen this year alone, reported the Associated Press. The Government of Pyongyang focuses on crypto hacking to fund its military program following harsh UN sanctions.

“South Korea’s main spy agency, the National Intelligence Service, said North Korea’s capacity to steal digital assets is considered among the best in the world because of the country’s focus on cyber crimes since UN economic sanctions were toughened in 2017 in response to its nuclear and missile tests.” reported the AP agency. North Korea cannot export its products due to the UN sanctions imposed in 2016 and 1017, and the impact on its economy is dramatic.

The NIS added that more than 100 billion won ($78 million) of the total stolen funds came from South Korea. Cyber security and intelligence experts believe that attacks aimed at the cryptocurrency industry will continue to increase next year. National Intelligence Service experts believe that North Korea-linked APT groups will focus on the theft of South Korean technologies and confidential information on South Korean foreign policy and national security.

Data published by the National Intelligence Service agency confirms a report published by South Korean media outlet Chosun early this year that revealed North Korean threat actors have stolen around $1.7 billion (2 trillion won) worth of cryptocurrency from multiple exchanges during the past five years.

  • UK Security Agency Wants Fresh Approach to Combat Phishing

The UK National Cyber Security Centre (NCSC) has called for a defence-in-depth approach to help mitigate the impact of phishing, combining technical controls with a strong reporting culture.

Writing in the agency’s blog, technical director and principal architect, “Dave C,” argued that many of the well-established tenets of anti-phishing advice simply don’t work. For example, advising users not to click on links in unsolicited emails is not helpful when many need to do exactly that as part of their job.

This is often combined with a culture where users are afraid to report that they’ve accidentally clicked, which can delay incident response, he said. It’s not the user’s responsibility to spot a phish – rather, it’s their organisation’s responsibility to protect them from such threats, Dave C argued.

As such, they should build layered technical defences, consisting of email scanning and DMARC/SPF policies to prevent phishing emails from arriving into inboxes. Then, organisations should consider the following to prevent code from executing:

  • Allow-listing for executables

  • Registry settings changes to ensure dangerous scripting or file types are opened in Notepad and not executed

  • Disabling the mounting of .iso files on user endpoints

  • Making sure macro settings are locked down

  • Enabling attack surface reduction rules

  • Ensuring third-party software is up to date

  • Keeping up to date about current threats

Additionally, organisations should take steps such as DNS filtering to block suspicious connections and endpoint detection and response (EDR) to monitor for suspicious behaviour, the NCSC advised.

  • GodFather Android malware targets 400 banks, crypto exchanges

An Android banking malware named 'Godfather' has been targeting users in 16 countries, attempting to steal account credentials for over 400 online banking sites and cryptocurrency exchanges.

The malware generates login screens overlaid on top of the banking and crypto exchange apps' login forms when victims attempt to log into the site, tricking the user into entering their credentials on well-crafted HTML phishing pages.

The Godfather trojan was discovered by Group-IB analysts, who believe it is the successor of Anubis, a once widely-used banking trojan that gradually fell out of use due to its inability to bypass newer Android defences. ThreatFabric first discovered Godfather in March 2021, but it has undergone massive code upgrades and improvements since then.

Also, Cyble published a report yesterday highlighting a rise in the activity of Godfather, pushing an app that mimics a popular music tool in Turkey, downloaded 10 million times via Google Play. Group-IB has found a limited distribution of the malware in apps on the Google Play Store; however, the main distribution channels haven't been discovered, so the initial infection method is largely unknown.

Almost half of all apps targeted by Godfather, 215, are banking apps, and most of them are in the United States (49), Turkey (31), Spain (30), Canada (22), France (20), Germany (19), and the UK (17).

Apart from banking apps, Godfather targets 110 cryptocurrency exchange platforms and 94 cryptocurrency wallet apps.

  • Companies Overwhelmed by Available Tech Solutions

92% of executives reported challenges in acquiring new tech solutions, highlighting the complexities that go into the decision-making process, according to GlobalDots.

Moreover, some 34% of respondents said the overwhelming amount of options was a challenge when deciding on the right solutions, and 33% admitted the time needed to conduct research was another challenge in deciding.

Organisations of all varieties rely on technology more than ever before. The constant adoption of innovation is no longer a luxury but rather a necessity to stay on par in today’s fast-paced and competitive digital landscape. In this environment, IT and security leaders are coming under increased pressure to show ROIs from their investment in technology while balancing operational excellence with business innovation. Due to current market realities, IT teams are short-staffed and suffering from a lack of time and expertise, making navigating these challenges even more difficult.

The report investigated how organisations went about finding support for their purchasing decisions. Conferences, exhibitions, and online events served as companies’ top source of information for making purchasing decisions, at 52%. Third-party solutions, such as value-added resellers and consultancies, came in second place at 48%.

54% are already using third parties to purchase, implement, or support their solutions, highlighting the value that dedicated experts with in-depth knowledge of every solution across a wide range of IT fields provide.

We are living in an age of abundance when it comes to tech solutions for organisations, and this makes researching and purchasing the right solutions for your organisation extremely challenging.

  • Nine in 10 Third-party Contractors, Freelancers Use Personal, Unmanaged Devices Likely to be Infected

Talon Cyber Security surveyed 258 third-party providers to better understand the state of third-party working conditions, including work models, types of devices and security technologies used, potentially risky actions taken, and how security and IT tools impact productivity.

Looking at recent high-profile breaches, third parties have consistently been at the epicenter, so they took a step back with their research to better understand the potential root causes. The findings paint a picture of a third-party work landscape where individuals are consistently working from personal, unmanaged devices, conducting risky activities, and having their productivity impacted by legacy security and IT solutions.

Here’s what Talon discovered:

  • Most third parties (89%) work from personal, unmanaged devices, where organisations lack visibility and cannot enforce the enterprise’s security posture on. Talon pointed to a Microsoft data point that estimated users are 71% more likely to be infected on an unmanaged device.

  • With third parties working from personal devices, they tend to carry out personal, potentially risky tasks. Respondents note that at least on occasion, they have used their devices to:

    • Browse the internet for personal needs (76%)

    • Indulge in online shopping (71%)

    • Check personal email (75%)

    • Save weak passwords in the web browser (61%)

    • Play games (53%)

    • Allow family members to browse (36%)

    • Share passwords with co-workers (24%)

  • Legacy apps such as Virtual Desktop Infrastructure (VDI) and Desktop-as-a-Service (DaaS) solutions are prominent, with 45% of respondents using such technologies while working for organisations.

  • UK Privacy Regulator Names and Shames Breached Firms

The UK Information Commissioner’s Office (ICO) has taken the unusual step of publishing details of personal data breaches, complaints and civil investigations on its website, according to legal experts.

The data, available from Q4 2021 onwards, includes the organisation’s name and sector, the relevant legislation and the type of issues involved, the date of completion and the outcome.

Given the significance of this development, it’s surprising that the ICO has (1) chosen to release it with limited fanfare, and (2) buried the data sets on its website. Indeed, it seems to have flown almost entirely under the radar.

Understanding whether their breach or complaint will be publicised by European regulators is one of – if not the – main concern that organisations have when working through an incident, and the answer has usually been no. That is particularly the understanding or assumption where the breach or complaint is closed without regulatory enforcement. Now, at least in the UK, the era of relative anonymity looks to be over.

Despite the lack of fanfare around the announcement, this naming and shaming approach could make the ICO one of the more aggressive privacy regulators in Europe. In the future, claimant firms in class action lawsuits may adopt “US-style practices” of scanning the ICO database to find evidence of repeat offending or possible new cases.

The news comes even as data reveals the value of ICO fines issued in the past year tripled from the previous 12 months. In the year ending October 31 2022, the regulator issued fines worth £15.2m, up from £4.8m the previous year. The sharp increase in the value of fines shows the ICO’s increasing willingness selectively to crack down on businesses – particularly those that the ICO perceives has not taken adequate measures to protect customer and employee data.
