Top Cyber Stories of the Last Week

Russian Hackers Target IT Supply Chain In Ransomware Attack Leading To Hundreds Of Firms Being Hit

Hackers began a ransomware attack on Friday, hitting at least 200 companies, according to cyber security researchers.

In what appears to be one of the largest supply chain attacks to date, hackers compromised Kaseya, an IT management software supplier, in order to spread ransomware to the managed service providers that use its technology, as well as to their clients in turn.

The attacks have been attributed t=to REvil, the notorious Russia-linked ransomware cartel that the FBI claimed was behind recent crippling attack on beef supplier JBS.

The attack is the latest example of hackers weaponising the IT supply chain in order to attack victims at scale, by breaching just one provider. Last year, it emerged that Russian state-backed hackers had hijacked the SolarWinds IT software group in order to penetrate the email networks of US federal agencies and corporations, for example.

Late on Friday, Kaseya urged those using the compromised “VSA server” tool, which provides remote monitoring and patching capabilities, to shut it down immediately.

71% Of Organisations Experienced BEC Attacks Over The Past Year

Business email compromise (BEC) attacks are one of the most financially damaging cyber crimes and have been on the rise over the past year. This is according to a new report which revealed that spoofed email accounts or websites accounted for the highest number of BEC attack as 71% of organisations acknowledged they had seen one over the past year. This is followed by spear phishing (69%) and malware (24%). Data from 270 IT and cyber security professionals were collected to identify the latest enterprise adoption trends, gaps and solution preferences related to phishing attacks.

Cyber Insurance Isn't Helping With Cyber Security, And It Might Be Making The Ransomware Crisis Worse, Say Researchers

Cyber insurance is designed to protect organisations against the fallout of cyber attacks, including covering the financial costs of dealing with incidents. However, some critics argue that insurance encourages ransomware victims to simply pay the ransom demand that will then be covered by the insurers, rather than have adequate security to deter hackers in the first place. Insurers argue that it's the customer that makes any decision to pay the ransom, not the insurer.

LinkedIn Breach Reportedly Exposes Data Of 92% Of Users, Including Inferred Salaries

A second massive LinkedIn breach reportedly exposes the data of 700M users, which is more than 92% of the total 756M users. The database is for sale on the dark web, with records including phone numbers, physical addresses, geolocation data, and inferred salaries. The hacker who obtained the data has posted a sample of 1M records, and checks confirm that the data is both genuine and up to date. No passwords are included, but as the site notes, this is still valuable data that can be used for identity theft and convincing-looking phishing attempts that can themselves be used to obtain login credentials for LinkedIn and other sites. https://9to5mac.com/2021/06/29/linkedin-breach/

Users Clueless About Cyber Security Risks

Organisations are facing yet another unprecedented threat to their cyber security now that employees are headed back into offices with their personal devices, lax security hygiene and no clue about some of the most catastrophic attacks in history, such as the Colonial Pipeline shutdown. A new survey shows the mountains of work ahead for security teams in not just locking down their organisations’ systems but also in keeping users from getting duped into handing over the keys to the kingdom. 2,000 end users were surveyed in the U.S. and found the dangers to critical infrastructure, utilities and food supplies are not sinking in with the public, despite the deluge of headlines.

Ransomware: Paying Up Won't Stop You From Getting Hit Again, Says Cyber Security Chief

Ireland's Health Service Executive (HSE) has been praised for its response after falling victim to a major ransomware attack and for not giving into cyber criminals and paying a ransom. HSE was hit with Conti ransomware in May, significantly impacting frontline health services. The attackers initially demanded a ransom of $20 million in bitcoin for the decryption key to restore the network. While the gang eventually handed over a decryption key without receiving a ransom, they still published stolen patient data – a common technique by ransomware attackers, designed to pressure victims into paying.

Don’t Leave Your Cyber IR Plan To IT, It’s An Organisational Risk

Phishing attacks, insider threats, denial of service disruptions, malware and ransomware — cyber security incidents like these happen on a daily basis. For most of these incidents, the onsite IT team will remediate based on a pre-developed plan and process. And for many of these incidents, that’s a solid approach. But those incident response plans and strategies are IT oriented and geared toward short-term fixes and single incident responses. Meaning, if an incident accelerates beyond a handful of infected laptops or a compromised server and begins to affect operations of all or even part of the organisation, business itself can be disrupted — or even shut down entirely.

Cyber Crime Never Sleeps

When the Colonial Pipeline fell victim to a ransomware attack, people across the United States were shocked to find that a single episode of cyber crime could lead to widespread delays, gas shortages and soaring prices at the pump. But disruptive ransomware attacks like these are far from rare; in fact, they are becoming more and more frequent. Cyber crime is on the rise, and our cyber security infrastructure desperately needs to keep up. A quick look at the data from the last year confirms that cyber crime is a growing threat. Identity theft doubled in 2020 over 2019.

IT, Healthcare And Manufacturing Facing Most Phishing Attacks

Researchers examined more than 905 million emails for the H1 2021 Global Phish Cyber Attack Report, finding that the IT industry specifically saw 9,000 phishing emails in a one month span out of almost 400,000 total emails. Their healthcare industry customers saw more than 6,000 phishing emails in one month out of an average of over 450,000 emails and manufacturing saw a bit less than 6,000 phishing emails out of about 330,000 total emails. Researchers said these industries are ripe targets because of the massive amount of personal data they collect and because they are often stocked with outdated technology that can be easily attacked.

Classified Ministry Of Defence Documents Found At Bus Stop

Classified Ministry of Defence documents containing details about HMS Defender and the British military have been found at a bus stop in Kent. One set of documents discusses the likely Russian reaction to the ship's passage through Ukrainian waters off the Crimea coast on Wednesday. Another details plans for a possible UK military presence in Afghanistan after the US-led NATO operation there ends. The government said an investigation had been launched.

Cabinet Office Increases Cyber Security Training Budget By Almost 500%

The UK’s Cabinet Office increased its cyber security training budget to £274,142.85 in the fiscal year 2021 – a 483% increase from the £47,018 spent in the previous year. In its FOI response, the Cabinet Office detailed the cyber security courses attended by its staff, revealing that the number of booked courses grew from 35 in 2019-20 to 428 in the current fiscal year.

Top Cyber Headlines of the Week

Ryuk gang estimated to have made more than $150 million from ransomware attacks

In a joint report published today, threat intel company Advanced Intelligence and cyber security firm HYAS said they tracked payments to 61 Bitcoin addresses previously attributed and linked to Ryuk ransomware attacks. "Ryuk receives a significant amount of their ransom payments from a well-known broker that makes payments on behalf of the ransomware victims," the two companies said. "These payments sometimes amount to millions of dollars and typically run in the hundreds of thousands range."

China's APT hackers move to ransomware attacks

Security researchers investigating a set of ransomware incidents at multiple companies discovered malware indicating that the attacks may be the work of a hacker group believed to operate on behalf of China. Although the attacks lack the sophistication normally seen with advanced threat actors, there is strong evidence linking them to APT27, a group normally involved in cyber espionage campaigns, also known as TG-3390, Emissary Panda, BRONZE UNION, Iron Tiger, and LuckyMouse.

SolarWinds hack: Amid hardened security, attackers seek softer targets

Reported theories by SolarWinds hack investigators that federal agencies and private companies were too busy focusing on election security to recognize vulnerabilities tied to the software supply chain are unfair and misleading. And yet, those same experts acknowledge that such accusations offer an important cyber security lesson for businesses: organizations must ensure that their entire attack surface receives attention.

Hackney Council files including alleged passport documents leaked online after cyber attack

The council in East London was hit by what it described as a "serious cyber attack" in October. It reported itself to the data watchdog due to the risk criminals accessed staff and residents' data. The council said it was working with the UK's National Cyber Security Centre (NCSC) and the Ministry of Housing to investigate and understand the impact of the incident.

PayPal users targeted in new SMS phishing campaign

Now, at first glance the message may not seem all that suspicious since PayPal may, in fact, impose limits on sending and withdrawing money. The payment provider usually does so when it suspects that an account has been accessed by a third party without authorization, when it has detected high-risk activities on an account, or when a user has violated its Acceptable Use Policy. However, in this case it really is a case of SMS-borne phishing, also known as Smishing. If you click on the link, you will be redirected to a login phishing page that will request your access credentials. Should you proceed to “log in”, your credentials will be sent to the scammers behind the ruse and the fraudulent webpage will attempt to gather further information, including the full name, date of birth address, and bank details.

SolarWinds, top executives hit with class action lawsuit over Orion software breach

SolarWinds and some of its top executives have been hit with a class action lawsuit by stockholders, who allege the company lied and materially misled them about security practices leading up to a massive breach of its Orion management software that has reverberated throughout the public and private sector.

The rise of cyber-mercenaries poses a growing threat for both governments and companies

These days, 21st century mercenaries are as likely to be seated behind a computer screen, wreaking havoc for their paymasters’ enemies as slugging it out on a real-world battlefield. But the rapid rise of cyber-mercenaries - or Private Sector Offensive Actors (PSOAs) - is vexing some of the biggest names in the global technology industry, and for good reason. Globally, the cyber security industry is already vast, raking in an estimated $156bn in revenues in 2019. It is set to nearly double in size by 2027.

Declutter Your Devices to Reduce Security Risks

Everyone should set aside time to review what they’ve installed on their various devices—typically apps, but that can also include games and addons. In fact, this should be an annual cleaning, at minimum.

You’re not just doing this because you want your device to look good. That’s one benefit you get from cleaning up your digital life, but it’s not the most important one. You’re also doing this to bolster your digital security. Yes, security.
