SIM Hijacking

SIM hijacking — or SIM swapping — is an attack where a fraudster contacts your cell phone provider and convinces them to switch your account to a phone that they control. Since your smartphone often serves as a security measure or backup verification system, this allows the fraudster to take over other accounts of yours. Sometimes this involves people inside the phone companies.

Phone companies have added security measures since this attack became popular and public, but a new study (news article) shows that the measures aren’t helping:

We examined the authentication procedures used by five pre-paid wireless carriers when a customer attempted to change their SIM card. These procedures are an important line of defense against attackers who seek to hijack victims’ phone numbers by posing as the victim and calling the carrier to request that service be transferred to a SIM card the attacker possesses. We found that all five carriers used insecure authentication challenges that could be easily subverted by attackers.We also found that attackers generally only needed to target the most vulnerable authentication challenges, because the rest could be bypassed.

It’s a classic security vs. usability trade-off. The phone companies want to provide easy customer service for their legitimate customers, and that system is what’s being exploited by the SIM hijackers. Companies could make the fraud harder, but it would necessarily also make it harder for legitimate customers to modify their accounts.

US Could Appoint a Cybersecurity Leader for Each State

US Could Appoint a Cybersecurity Leader for Each State

The USA is considering legislation that would protect local governments by requiring the appointment of a cybersecurity leader for each state.

Backers of the Cybersecurity State Coordinator Act of 2020 say the proposed law will improve intelligence sharing between state and federal governments and speed up incident response times in the event of a cyber-attack.

Under the legislation, the director of the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency would be tasked with appointing an employee of the agency in each state to serve as cybersecurity state coordinator. 

Money to create these positions would come from the federal government, which would be required to ring-fence the necessary funding. 

The role of each state coordinator would be multifaceted, combining elements of training, advisory work, and program development.

Each leader would serve as a principal federal cybersecurity risk advisor, coordinating efforts to prepare for, respond to, and remediate cyber-attacks. Another core responsibility would be to raise awareness of the financial, technical, and operational resources available to nonfederal entities from the federal government.

Coordinators would be expected to support training, exercises, and planning for continuity of operations to expedite as swift a recovery as possible from cybersecurity incidents. Furthermore, they would be called on to assist nonfederal entities in developing and coordinating vulnerability disclosure programs consistent with federal and information security industry standards.

“State, local, Tribal, and territorial entities face a growing threat from advanced persistent threat actors, hostile nation states, criminal groups, and other malicious cyber actors,” reads the bill. “There is an urgent need for greater engagement and expertise from the Federal Government to help these entities build their resilience and defenses.”

The bill, which has attracted bi-partisan support, was introduced by Senators Maggie Hassan and Gary Peters and is co-sponsored by senators John Cornyn of Texas and Rob Portman of Ohio.

Portman said: “This bipartisan bill, which creates a cybersecurity state coordinator position, would help bolster state and local governments’ cybersecurity by facilitating their relationship with the federal government to ensure they know what preventative resources are available to them as well as who to turn to if an attack occurs.”

Possessing Ransomware Could Become Illegal in Maryland

Possessing Ransomware Could Become Illegal in Maryland

Lawmakers in the state of Maryland are considering making it a criminal offense to be in possession of ransomware. 

A bill was introduced on Tuesday, January 14, that seeks to penalize Marylanders who knowingly possess the malware and intend to use it to cause harm. The bill also grants victims of a ransomware attack the right to sue the hacker for damages in civil court. 

The state has already outlawed the use of malicious technology to extort money out of victims. Senate Bill 30, which was heard before the Senate Judicial Proceedings Committee last week, would make it a misdemeanor to be in possession of ransomware with the intent to use it in a malicious manner.

Any person convicted of this misdemeanor could face 10 years in prison and/or a fine of up to $10,000. 

The proposed law would not apply to cybersecurity researchers who may be in possession of ransomware for innocent research purposes.

Senator Susan Lee, who is the lead sponsor of the bill, said that it “gives prosecutors tools to charge offenders.”

Assuming a remarkable level of naiveté on the part of cyber-criminals who use ransomware to extort vast sums of money from organizations and individuals, Lee said that it was “important to establish [the bill] so criminals know it’s a crime.”

In January 2019, the Salisbury, Maryland, police department suffered a ransomware attack that prevented officers from accessing the department’s computer network. Four months later, Baltimore, the state’s largest urban conurbation, was hit by a ransomware attack that is estimated to have cost around $18m. 

Possessing ransomware is already a criminal offense in several US states, including Michigan and California. The fight against ransomware was led by Wyoming, which in 2014 became the first state to make it illegal to possess ransomware, spyware, adware, keyloggers, and several other types of malware.

There’s no denying that ransomware is causing problems in the United States. In 2019 alone, this particular strain of malware impacted at least 113 state and municipal governments and agencies, 764 healthcare providers, and 89 universities, colleges, and school districts, with estimated costs of $7.5bn. 

According to a ransomware report by cybersecurity firm Emsisoft,”the only way to stop ransomware is to make it unprofitable, and that means the public sector must practice better cybersecurity so that ransoms need not be paid.”

Mitsubishi Electric Discloses Information Leak

Mitsubishi Electric Discloses Information Leak

Japanese company Mitsubishi Electric has today disclosed an information leak that occurred over six months ago. 

The century-old electronics and electrical equipment manufacturing firm announced the breach by issuing a brief statement on its website.

An official internal investigation was launched after suspicious activity was observed taking place on June 28, 2019. The company said that upon noting the unusual behavior on the network, measures were immediately taken to restrict external access. 

According to Nippon.com, hackers accessed servers and computers at Mitsubishi headquarters and other offices belonging to the company in a large-scale cyber-attack. 

Mitsubishi said: “We have confirmed that our network may have been subject to unauthorized access by third parties and that personal information and corporate confidential information may have been leaked to the outside.”

Mitsubishi announced the breach today after it was reported by two newspapers, the Asahi Shimbun and Nikkei. A theory put forward by both local papers is that the attack was initiated by a cyber-espionage group with links to the People’s Republic of China. 

While Nikkei reported that hackers swiped 200 MB of information from Mitsubishi, the manufacturer claims that its investigation of the incident uncovered no evidence that any sensitive data connected to its business partners or government defense contracts had been stolen or misused. 

In a statement no doubt intended to reassure Mitsubishi’s corporate parents, the company wrote: “As a result of an internal investigation, it has been confirmed that sensitive information on social infrastructure such as defense, electric power, and railways, highly confidential technical information, and important information concerning business partners has not been leaked.” 

When announcing the incident, Mitsubishi didn’t explain why it had waited so long after discovering the breach to go public with the news. However, the inclusion of the comment “to date, no damage or impact related to this matter has been confirmed” could imply that the company chose to hold back information until it had a clear idea of what the effects of the breach might be.

Japan’s chief cabinet secretary Yoshihide Suga said the government had been informed of the cybersecurity breach and that there was no leak of information related to defense equipment or to the electric power sector.

€114m in Fines Imposed by Euro Authorities Under GDPR

€114m in Fines Imposed by Euro Authorities Under GDPR

Data protection regulators have imposed €114m ($126m/£97m) in monetary fines under the GDPR for a wide range of infringements, according to new findings from DLA Piper.

Whilst not all fines were related to data breach infringements, DLA Piper’s latest GDPR Data Breach Survey found that more than 160,000 data breach notifications have been reported across the 28 European Union Member States since the GDPR came into force on May 25 2018.

In terms of the total value of fines issued by geographical region, France (€51m), Germany (€24.5m) and Austria (€18m) topped the rankings, whilst the Netherlands (40,647), Germany (37,636) and the UK (22,181) had the highest number of data breaches notified to regulators.

The highest GDPR fine to date was €50m, imposed by the French data protection regulator on Google, for alleged infringements of the transparency principle and lack of valid consent. Earlier this year, the UK ICO published intentions to fine British Airways £183.39m and Marriott £99m following two high profile data breaches, although neither fine has been finalized at the time of writing.

Ross McKean, a partner at DLA Piper specializing in cyber and data protection, said: “GDPR has driven the issue of data breach well and truly into the open. The rate of breach notification has increased by over 12% compared to last year’s report and regulators have been busy road-testing their new powers to sanction and fine organizations.

“The total amount of fines of €114m imposed to date is relatively low compared to the potential maximum fines that can be imposed under GDPR, indicating that we are still in the early days of enforcement. We expect to see momentum build with more multi-million Euro fines being imposed over the coming year as regulators ramp up their enforcement activity.”

Travelex Begins Reboot as VPN Bug Persists

Travelex Begins Reboot as VPN Bug Persists

Under-fire foreign currency firm Travelex has claimed its first customer-facing services in the UK have gone live after a crippling ransomware attack in December, with experts suggesting an unpatched VPN bug may have been to blame.

The London-headquartered business has been slammed by customers after the suspected Sodinokibi (REvil) ransomware struck on December 31, forcing it to take systems offline as a precautionary measure.

Several complained that the foreign currency they ordered and paid for online is unavailable, leaving them out of pocket. The outage affected not just Travelex’s websites but its bricks-and-mortar outlets and services it provides to major UK high street banks such as Barclays and RBS.

However, the firm claimed in an update on Friday it has been working hard this month to restore online and customer-facing systems.

“On 17 January 2020, we confirmed that the first of our customer-facing systems in the UK were live and that the phased restoration of our systems globally was now firmly underway. We are prioritizing the UK as this is our single largest market,” it said.

Although unconfirmed, security experts believe that an unpatched critical vulnerability in Pulse Secure VPNs (CVE-2019-11510) may have allowed attackers to remotely execute malicious code on Travelex IT systems.

Troy Mursch of Bad Packets claimed to have reached out to the firm in September to flag the software flaw, which has a CVSS score of 10.0, but received no response.

On Friday, he said that there are still over 3000 vulnerable Pulse Secure VPN servers out there. That’s bad news because the bug is seeing “wide exploitation,” despite the fact that a patch has been available since April 2019, according to the US Cybersecurity and Infrastructure Security Agency (CISA).

“A remote, unauthenticated attacker may be able to compromise a vulnerable VPN server. The attacker may be able to gain access to all active users and their plain-text credentials,” CISA said of CVE-2019-11510.

“It may also be possible for the attacker to execute arbitrary commands on each VPN client as it successfully connects to the VPN server.”

Although Travelex maintains that there is “no evidence that any data has left the organization,” the hackers behind the $6 million ransom demand have claimed they exfiltrated 5GB of sensitive customer data last year.

London Councils Lose Nearly 1300 Devices Over Three Years

London Councils Lose Nearly 1300 Devices Over Three Years

The number of London councils reporting lost or stolen mobile computing devices has more than doubled over the past three financial years, according to new Freedom of Information (FOI) data.

Think tank Parliament Street compiled responses from 23 out of the 31 local borough councils that operate across the UK capital.

It found that a total of 1293 devices were lost or stolen over the three financial years from 2016, including laptops, mobile phones and tablets. The figure jumped from 304 in 2016-17 to 635 in 2018-19, a 109% increase.

Phones went missing most often, accounting for 951 lost or stolen devices over the period. The figure rose 122%, from 215 in 2016-17 to 478 in 2018-19.

Laptop losses also almost doubled over the period, from 64 to 124, while tablet losses increased slightly from 26 to 33.

Lambeth was most affected by missing devices, recording 281 losses, 84% of which were mobile phones. Next came Richmond and Wandsworth (123) and Brent (170). Richmond and Wandsworth, which reported together, saw a 666% increase in lost and stolen devices, while the figure stood at 74% in Brent.

Absolute Software EMEA VP, Andy Harcup, warned that the rise of flexible working combined with opportunistic thieves is increasing the risk of confidential public sector data going missing.

“If said device ends up in the wrong hands, these councils and the constituents they serve could be facing severe consequences, including a major data breach with citizen details finding their way onto the dark web,” he added.

“It’s time for all organizations to wake up to the very real risks posed by stolen devices in terms of data security. Every single council should have robust end-point security measures in place to ensure that devices reported missing can be accessed, tracked, deleted and frozen appropriately.”

Citrix Patches ADC Bug as Attacker Hoards Access

Citrix Patches ADC Bug as Attacker Hoards Access

Citrix has begun issuing patches for a serious vulnerability in its Application Delivery Controller (ADC) product which experts have warned is being exploited in the wild.

The tech giant revealed the CVE-2019-19781 bug in ADC and its Citrix Gateway back in December. If successfully exploited, it could allow an unauthenticated attacker to perform arbitrary code execution.

Although the firm announced a series of mitigations to help protect customers as it readied a permanent fix, researchers claimed to have discovered tens of thousands of users that were still exposed, including high value targets across verticals including finance, government and healthcare.

Part of the problem appeared to be that not all of these mitigations worked as intended. The Dutch authorities urged businesses to disable Citrix systems altogether.

With proof-of-concept exploits appearing online in recent days and reports of active attacks, Citrix appeared to accelerate the process of readying patches.

Permanent fixes for ADC versions 11.1 and 12.0 are now ready and it has “moved forward” availability dates for other versions 12.1, 13 and 10.5 to January 24. Its Citrix SD-WAN WANOP product will also be patched on the same day.

The news comes as FireEye warned it had spotted “dozens of successful exploitation attempts” against ADC deployments that had not put in place temporary pre-patch mitigations.

One particular payload, which it named “NotRobin,” appears to be hoarding access to exposed Citrix systems.

“FireEye believes that the actor behind NotRobin has been opportunistically compromising NetScaler devices, possibly to prepare for an upcoming campaign. They remove other known malware, potentially to avoid detection by administrators that check into their devices after reading Citrix security bulletin CTX267027,” FireEye explained.

“NotRobin mitigates CVE-2019-19781 on compromised devices but retains a backdoor for an actor with a secret key. While we haven’t seen the actor return, we’re skeptical that they will remain a Robin Hood character protecting the internet from the shadows.”
